One supplier quoted a TZ and another quoted an NSa. Which one is right for us?

It comes down to three things - how many people sit behind it, how fast your internet line is, and whether anything is hosted in your own building. TZ models are built for small offices, shops and branches on ordinary broadband or fibre. NSa models are for head offices, factories and anywhere with several hundred staff, more than one link, or servers that outsiders connect into. If you land on the borderline, take the larger one: moving up later means buying a whole new appliance, not slotting in a card.

The datasheet quotes an enormous speed. Will we actually get that?

No, and anyone promising you that figure is quoting the wrong line of the datasheet. Headline throughput is measured with the security features switched off; turn on virus scanning, intrusion prevention and inspection of encrypted sites and the real number falls a long way, often to a fraction of the top figure. The number worth reading is the one marked for threat prevention or deep inspection. We size against that, with headroom for the faster internet line you will buy in two years, which is why our recommendation sometimes looks a size bigger than you expected.

What happens to an attachment that nobody has ever seen before?

It is held at the gateway and opened first in a cloud test-room, where several engines run it and watch what it tries to do (Capture ATP). The part that catches current ransomware is the memory check: malware that only unpacks itself while running is caught in the act inside processor memory, which a signature scanner never gets to see (RTDMI). If the file behaves, it is released to the recipient in about a minute; if not, it is blocked and logged with the sender's details. You choose whether to hold every file until the verdict or deliver first and alert afterwards - the first is safer, the second keeps a sales team happier.

Our new branch opens next month and there is no IT person there. How does the firewall get set up?

We register the unit to your account at our bench, then courier it to the branch, where somebody plugs in power and the internet cable and it downloads its own settings and comes online - nothing technical is typed at the far end (zero-touch deployment). That removes an engineer's travel and hotel from the bill for every new site you open. One condition: the broadband at the branch must genuinely be live on the day the box arrives, and telecom activation is the thing that slips most often. For a complicated branch with its own server or two internet lines, we still prefer to send an engineer.

If the internet at one shop goes down, do the billing counters stop?

Not if there is a second path in place. The unit will take a broadband line and a 4G SIM together, watch the quality of both, and shift traffic to the healthy one by itself when the main link fails (SD-WAN failover). Billing, card machines and cloud accounting carry on over the backup - slower, but working, which is the difference between a poor hour and a closed shop. Two honest caveats: the switchover takes several seconds, so a video call may drop once, and mobile data is billed at whatever your operator charges, which for a chain across Kolkata is worth checking before you enable it everywhere.

Our CCTV recorder has to be viewable from outside. Can that be done safely?

Yes, though not the way it is usually done. The common shortcut is opening a port straight through to the recorder, and those recorders are among the most attacked devices on the internet - default passwords, firmware nobody has touched in years. The safer arrangement is a VPN login for the handful of people who need to view, or the camera maker's own cloud relay, with the recorder kept in an isolated lane of its own. Where a direct port is genuinely unavoidable we restrict it to named source addresses and put intrusion prevention in front of it, and we will still ask you to change that recorder's password first.

Does it stop staff copying files onto a pen drive?

No. A USB stick never touches the network, so the firewall simply cannot see it. What it can do is stop the same file leaving by webmail, a personal cloud drive or a file-sharing site, and keep a record of who attempted it, which covers the routes people actually use. Locking USB ports properly needs software on each computer or a Windows policy, and we are happy to set that up as a separate piece of work. Anyone claiming a firewall on its own prevents data walking out of the building is overselling it.

How long will this box last before we have to buy another?

Expect several years of working life, governed by two published dates rather than by wear: end-of-sale and end-of-support for that particular model. Hardware seldom dies of old age in a ventilated rack; what forces the change is a model dropping off the support list, or your internet becoming fast enough that the appliance turns into the bottleneck. We check both dates before quoting, so nobody gets sold something already halfway through its life. When replacement day does arrive, settings export and import, so it is an evening's work and not a rebuild from scratch.

Will this protect laptops once they leave the office?

Only partly, and it is worth being blunt about that. Traffic that comes back through the office, whether over the VPN or from a device physically in the building, is inspected; a laptop sitting on hotel WiFi is on its own. Some customers set the VPN to connect on its own so travelling staff always come home through the firewall, which works well but adds a little delay to everything. For a genuinely mobile team you still want antivirus on the machine itself - this is not a replacement for it.

Can the same box run our office WiFi?

Yes. The firewall doubles as the wireless controller, and the access points feed off your existing network cabling. Because one unit is doing the security work as well, guest WiFi, staff WiFi and the billing network each get their own lane and their own rules from a single screen, instead of a row of home routers that nobody manages. Coverage is still a physical matter, though: thick walls, a mezzanine floor or a metal-clad godown will need more access points than a plasterboard office of the same area. We walk the floor around Kodalia before quoting and give you the honest number.

Why buy through Microtech Solutions rather than the cheapest listing online?

Because you are not just buying a box - you are buying a licence registered to somebody's name, and cheap online stock is often registered elsewhere, imported without local warranty, or sold with a bundle far shorter than the listing implies. We register both the hardware and the subscription to your company, keep the paperwork where you can find it at audit time, and are the people who turn up when the link drops. You also get the sizing conversation before the money is spent instead of a return request afterwards. Compare the total of hardware, bundle, installation and support across Kolkata, not the sticker price on its own.

Can we manage the switches and access points from the same screen too?

Yes, and it saves more time than people expect. Supported switches and wireless access points are adopted by the firewall and appear inside the same console, so a new lane for the CCTV recorder, or a change to the guest WiFi password, is done once and pushed out everywhere (SonicOS management). One login, one place to look when something misbehaves, instead of three web pages and three forgotten passwords. Older third-party switches will not join in - those carry on being managed separately, and we say so at the site survey rather than after the invoice.

Head office wants to see every branch on one screen. Is that possible?

Yes. Every unit reports into one cloud dashboard, so each site's status, alerts and firmware level sit in a single list (Network Security Manager). Policy templates are pushed from the same place, which means a newly blocked category or a changed password reaches thirty branches in one action rather than thirty separate logins. Reports come per branch or rolled up for the whole group, which is normally what auditors and franchise head offices want to see. The console is a licensed extra, so include it when you compare quotes for a multi-site rollout - it is a common omission.

The quote shows the box on one line and three more charges underneath. What are those?

Those extra lines are the subscriptions, and they are the part buyers most often miss when comparing two quotes. The hardware price alone gets you a working router and firewall; the other lines buy virus scanning, website categories, the cloud test-room for unknown files and the right to phone support, sold together as a security bundle for one, three or five years. Suppliers package these differently, so a cheaper-looking quote usually has a thinner bundle or a shorter term hiding inside it. Ask anyone quoting you - including us - to show hardware, bundle and term as three separate numbers.

Nobody here knows networking. Who manages it after you leave?

We can, and most of our customers choose exactly that - the firewall goes onto a yearly support contract and they simply ring us. That covers rule changes, renewals, firmware, the occasional wrongly blocked website and somebody answering when the link dies late at night. If you would rather keep it in-house, we train whoever is nearest to it on the four or five things they will realistically need: adding a user, unblocking a site, reading the monthly report, taking a config backup. What we will not do is hand over an appliance that nobody in your company can log into.

SonicWALL Business Network Security & Failover Setup near Kodalia

A franchise operator with eleven outlets asked us to connect the lot without sending an engineer to every town. We prepared the units at our own bench, couriered them out, and each shop manager plugged in power and the internet cable while the box pulled its own settings down and joined the private network on its own (Zero-Touch Deployment). Nine sites were live by that afternoon; two waited on a broadband fault the ISP had yet to clear. That is how a chain grows without hiring IT in every city.

💼 Buying SonicWALL UTM Firewall Appliance for Branch and Head Office Without the Guesswork in Kodalia

Boxed appliance opened on a table with its power adapter and mounting kit near Kodalia

The owner is convinced the office spends half the afternoon on video, the staff insist the internet is simply slow, and neither side has any evidence. Category filtering closes the obvious time sinks during working hours only, while per-person reports show who actually used what. Most of the argument disappears in the first week, usually because the real culprit turns out to be a machine nobody was sitting at. Rules can be softer for management and stricter for the shop floor, with nobody maintaining a spreadsheet.

The lease is signed, the outlet opens in three weeks, and your one IT person is already booked at head office that fortnight. A SonicWALLUTM Firewall Appliance for Branch and Head Office can be registered here, couriered to the site and brought online by whoever is standing there with a plug and an internet cable. The rules, the Wi-Fi settings and the tunnel back to head office arrive by themselves once it powers up. Chains adding shops around Kodalia use this so opening dates stop depending on somebody's travel calendar (Zero-Touch Deployment).

🤝 What You Get That Cheaper Options Skip in Kodalia

Nobody enjoys finding out, halfway through a bad week, that the security subscription lapsed in March. We put the hardware, the bundle and the renewal date on one page in writing, and say plainly which services an office like yours will actually use. If a service in the bundle would never earn its keep in your office, we say so rather than let it pad the invoice. Businesses around Kodalia usually find the licence conversation more useful than the hardware one.

The commonest firewall mistake is not buying the wrong brand, it is buying one model too small and then switching features off to keep it comfortable. We size against your real headcount, your internet speed and what you expect to add over the next two or three years, then leave headroom above that. A TZ suits a shop or a branch anywhere in Kolkata; an NSa suits a head office carrying branch tunnels and remote staff. Getting that choice right once costs far less than replacing the box in year two.

Design Studios Moving Very Large Files across Kolkata

A multi-brand car dealership on the outskirts of Kolkata ran the showroom, the workshop tablets and the spares counter on one flat network, and the dealer management system stalled whenever the service team uploaded job photographs. We separated the three areas and reserved a fixed share of the line for the dealer system and the phones. Customer Wi-Fi in the lounge now sits on its own lane and cannot reach anything internal. The service manager has stopped keeping a paper copy of every job card.

🛡️ RACK WORK, LABELLING AND CABLE ORDER

Who Comes to Site and What They Do

Most of the money wasted on firewalls is wasted at the sizing stage. We ask how many people are online together, how much of that traffic you intend to inspect, and whether branches are joining in - then quote the model that survives a bad Monday. Equally, if the smaller TZ is genuinely enough, we say so, because selling you an NSa you do not need is a short win and a long problem.

These are the tasks we are usually called in for:

▪Moving Off Your Old Firewall Without Downtime

▪Logins That Follow the Person: Directory Sign-On Setup

▪Site-to-Site and Work-from-Home VPN Setup

▪A Standby Box So One Failure Does Not Stop Work

*On scope: questions raised after the settling-in period become a paid engagement with us, not a ticket on the vendor's helpdesk.*

💡 Engineering Fact: Two internet lines are never identical, and the firewall knows it. It measures delay and lost packets on each one continuously, so your calls can sit on the steady line while big downloads go over the other.

🧰 SUPPORT & SPARES

A dead gateway on a Saturday is not the moment to start hunting for a phone number. Yearly support covers a stated response time, firmware patching and a standby unit for sites around Kodalia.

See What Support Covers →

🧾 Available Options and Typical Fit in Kolkata

Failover support, wireless capacity and switch limits are listed too:

TZ Desktop Firewalls for a Shop or Single Branch

The small box that sits on a shelf behind the counter and guards one or two internet lines. Right for a showroom, a clinic, a site office or any team of roughly five to fifty people.

🔹 WIFI BUILT IN

Several models carry their own wireless, which saves buying a separate access point in a one-room office.

🔹 BEST FOR

A single location of about five to fifty staff - one showroom, one clinic, one small factory office.

🔹 WHEN YOU GROW

A rack tray is available later, for the day the box has to move off the shelf and into a cabinet.

NSa Rack Firewalls for a Head Office or Campus

One-rack-unit NSa gateways for the main office of a company, a nursing home group or a college - anywhere a few hundred people share the same line from morning to night. Built to bolt into the cabinet you already own.

🔹 WORKING PACE

Virus scanning, intrusion checks and encrypted-site inspection can all run together while the branch tunnels stay usable.

🔹 RULES FOLLOW THE PERSON

Because the firewall reads who signed in to Windows, a manager gets manager access from any desk in the building (Single Sign-On).

🔹 HEAT

A warm server room is survivable. A sealed one with a dead AC is not, and heat is what shortens the life of every unit in that cabinet.

Heavy 2U Units for Data Centres and Big Campuses

The two-rack-unit NSa and NSsp appliances, for data centres, multi-building campuses and networks carrying tens of thousands of connections at once. Anything that can fail comes doubled.

🔹 NOISE

Nobody enjoys sitting next to one of these. Plan for a real server room, not a cabin behind the accounts desk.

🔹 PORT SPEEDS

Twenty-five and forty-gigabit fibre sockets are on offer, which keeps the security check from becoming a queue between server rows.

🔹 BOTH UNITS WORKING

A pair can run live together rather than leaving one idle, which at this price is a better use of the money (Active-Active clustering).

Branch Boxes That Set Themselves Up (Zero-Touch SD-WAN)

For the extra showroom, the godown office, the site cabin. You courier the unit, somebody local plugs in power and internet, and it pulls down its own settings and joins the head office network.

🔹 BUILD

Metal case, low power draw, and it copes with a dusty stores room far better than the plastic router the ISP left behind.

🔹 JOINING SITES

Encrypted tunnels build themselves between locations, instead of every branch hair-pinning its traffic through the main office.

🔹 COST NOTE

A branch unit and its subscription usually work out below a leased line to the same location, which is the whole argument for SD-WAN.

SonicWave WiFi Access Points for Full Floor Coverage

SonicWave units screwed to the ceiling so the signal reaches the far end of the floor. For any building where the WiFi works near the router and nowhere else.

🔹 CABLE POWER

One cable does both jobs, signal and electricity, which is why mounting height stops being an electrical problem (PoE).

🔹 WHERE IT SUITS

Factory floors, hostels, showrooms with roaming billing tablets, and offices that have run out of desk network points.

🔹 VISITORS

Guests get their own name, their own login page and an expiry, kept well away from the machines running your accounts.

Managed Switches on the Same Console as the Firewall

Switches that report to the same screen as the firewall, so ports, cameras and phones are handled from one login. For offices past the stage of stacking small unmanaged boxes under a desk.

🔹 WHAT IT'S FOR

Replacing the chain of little unmanaged switches that has grown under the desks, one added per problem over five years.

🔹 SUITS

Warehouses, hospitals and any premises where the camera count has quietly doubled since the cabling was first laid.

🔹 POWER OVER THE CABLE

Cameras, IP phones and access points draw electricity from the network cable, so no adaptor sits stranded above a ceiling tile (PoE).

Cloud Edge: Office Access for Staff Working from Home

Lets a person reach the one office server they need from home, a hotel or a client's site, without their laptop landing inside everything you own. Bought per person, not per building.

🔹 HOW IT DIFFERS

Rather than putting a laptop inside everything, each person is handed only the servers and applications they have been cleared for.

🔹 NO BOX AT HOME

The service runs from the cloud, so somebody who joins today is not waiting for hardware to be couriered to their flat.

🔹 RECORDS

Who connected, when, and to which server - the report exists whether or not anybody ever asks to see it.

Network Security Manager: Every Branch on One Screen

A cloud console that shows all your firewalls together - rules, alerts, firmware and reports. Worth it once you have more than two or three locations to keep an eye on.

🔹 FIRMWARE

Updates get scheduled for a Sunday night across the whole estate, rather than done one branch at a time over a month.

🔹 AUDIT TRAIL

Every configuration change is recorded against a name and a time, which settles most arguments before they properly start.

🔹 ALERTS

A branch losing its line, or a licence coming up for expiry, reaches you by mail before the branch manager rings.

Security Bundles and Licence Renewals

Firewalls are sold with a subscription behind them: threat updates, filtering, sandbox checks and vendor support. This is how those are bought, bundled and renewed without leaving a gap.

🔹 WHAT YOU ARE PAYING FOR

Not the metal box. You are paying for current threat information, category lists, and somebody to call when it misbehaves.

🔹 WHEN A RENEWAL IS THE WRONG ANSWER

If headcount has doubled since you bought, ask for a comparison against a larger unit before you sign anything.

🔹 BUYING PIECE BY PIECE

Individual modules can be added one at a time, which suits a site that only wants filtering, but the dates then drift apart and one always gets missed.

🗒️ Capacity, Limits and Sizing Guide in Kodalia

Two numbers govern sizing beyond raw speed: how many connections the unit holds at once, and how many remote users can be signed in together. A shop in Kodalia with ten machines and a camera recorder uses more connections than people expect, and a work-from-home week doubles the second figure. Give us your peak rather than your average and the model we quote will have room in it.

The appliance is one buy and the protection is another. On its own the box joins your offices together, decides who can reach what, and carries staff in over a VPN. The yearly subscription is what scans for viruses, blocks intrusions and unwanted websites, and tests unknown files in the cloud. When a subscription lapses the unit keeps routing traffic and quietly stops learning about anything new.

🏆 CORE PARAMETER🔹 How it scansThe whole stream is reassembled and read, with no cap on file size (RFDPI)

🔹 If the box diesActive-Standby or Active-Active pair with stateful failover

🔹 Where you manage itSonicOS web screen, command line, or Network Security Manager in the cloud

🔹 Network socketsCopper 1GbE on every model, 2.5GbE multi-gig on the TZ 570 and 670, and 10GbE SFP+ fibre on the larger rack units - the mix depends on the model ordered

🔹 Linking your branchesIPsec site-to-site tunnels, SSL VPN for staff, Secure SD-WAN across lines

SonicWALL Factory Checks Before a Box Is Sealed

Wireless access points and managed switches are administered from the same interface as the firewall. Network policy, guest access and port power are handled in one place, which removes both a controller appliance and a separate management server from the site.

If one internet line dies at eleven in the morning, your billing counter should not. Two or three connections, a mobile modem included, are measured all the time and traffic is moved onto whichever is behaving; when the dead line returns, your branch tunnels come back on their own without anyone travelling to site (Secure SD-WAN).

⚙️ SYSTEM EVALUATION & CHECKLIST

Turnkey UTM Firewall Appliance for Branch and Head Office Metrics Checklist near Kodalia

🛠️ Workflow Setup

Day one is a survey and nothing else. An engineer spends an hour or two counting users and devices, finding where the internet really lands, and checking the cabinet for room and power. Nothing on your network is touched.

⚠️ Pitfalls to Avoid

Ignoring alert mails for a month teaches everybody that alerts do not matter. Quieten the noisy ones in the first fortnight instead of muting the lot.

🔌 Guidelines & Sizing

Check the fibre module matches what your switch expects before it ships. Two modules can look identical and be built for different distances, and the wrong one links up and then drops packets in a way that looks exactly like an internet fault.

📈 Upgrade Triggers

Somebody has started keeping a list of which sites to try when the internet feels stuck, and restarting the router at three in the afternoon has become part of the job.

📄 How Issues Are Logged, Tracked and Closed in Kodalia

Type of Business	What the Work Covers	Typical Lead Time
Business Centres and Shared Office Floors	A private lane and a fair slice of the line for each tenant, with no way to browse into the company at the next desk	Survey first, cutover on an agreed weekend
Small Factories and Fabrication Units	Machines, cameras and office computers on separate lanes, plus a link to the sales office that holds through the shift	Around three working days in most service areas
Franchise Outlets and Brand Stores	One rule set built once and copied to every new outlet, so a store opening in another city works the day its box is plugged in	Usually within a week of the order, subject to stock

WHAT WORKS IN DAILY USE SUMMED UP

WHO IT DOES NOT SUIT - BEFORE YOU SIGN

✓When the fibre drops in the middle of billing, the second line picks the traffic up on its own rather than waiting for someone to notice (Secure SD-WAN).

—The smaller desktop models run off an external adapter. If that adapter fails, the site stays down until a replacement physically arrives.

✓A camera recorder chattering all day used to drag the billing counter down with it; each now sits in its own lane, and a compromised device has nowhere to travel (zone-based VLANs).

—Single sign-on only names people whose accounts live in your directory. Contractors and shared machines will still appear as bare IP addresses in the report.

✓Ransomware written last week matches nothing on a signature list, so suspicious files are watched while they run instead of being judged on what they look like (RTDMI).

—A proper cabinet with front-to-back airflow is expected for the 1U and 2U models. Balanced on a shelf above a photocopier, they run hot and age fast.

✓The audit question - who reached what, and when - is answered from the reports instead of from memory.

—Firmware upgrades drop live sessions for a moment. On a single appliance that means an after-hours window agreed with whoever works late.

✓Half the trouble in a small office starts with one shared login that everybody knows. Once each person signs in as themselves, the report finally names who did what (Single Sign-On with Active Directory).

—Rack units are loud. Put one in the corner of an open office and you will hear about it within a fortnight.

💡 Engineering Fact: An attachment nobody in the world has seen before is held back for a couple of minutes and opened inside a cloud test room first. If it starts encrypting files there, your accounts team never receives it (Capture ATP).

Read the power and earthing points twice - far more units die from a bad supply than from anything arriving over the internet.

📌 Power and Backup - Our Standards for busy workplaces

🔹Set a reliable time source on the appliance before go-live. Logs carrying the wrong timestamp are useless during an audit and worse during an incident.
🔹Certificate warnings on every second website are the usual first-week complaint. Push the inspection certificate to company machines through your office login system (Group Policy) before go-live, and leave banking and health sites off the inspection list altogether.
🔹Register the appliance and switch the security subscriptions on before cutover night at your office in Kodalia - a unit downloading its first threat update while thirty people wait is an avoidable delay.

👀 What Our Team Sees on Site in Kodalia

Design the zones before you write a single rule. I still find installations across Kolkata where cameras, accounts machines and guest Wi-Fi all sit in one zone called LAN, which means every future rule has to be an exception to something. Half a day of zone planning at the start saves a rule table nobody dares touch three years later.

Cloud-only filtering works on a laptop that has the agent installed and an internet connection. It does nothing between two machines standing in the same shop, and nothing at all for equipment that can never carry an agent.

A shop-grade wireless router with the word firewall printed on the carton gives you no user identity, no separation between the guest and the till, and a weekly reboot as its maintenance plan.

💡 Engineering Fact: When a hole is discovered in Windows or in your ERP server, the official fix takes weeks to test and apply. Meanwhile the firewall can recognise and block the attack that uses it, which is what buys you those weeks (intrusion prevention).

Frequently Asked Questions

Q. What happens when the subscription expires - does it just stop protecting us?

It keeps passing traffic quite normally, so nobody notices a thing on the morning it lapses, and that is exactly the danger. Virus definitions stop updating, newly malicious websites stop being categorised, and unknown attachments stop being tested in the cloud, leaving you defended against last year's threats. Firmware updates and support calls fall away too, which matters most on the day something breaks. Most bundles allow a short grace period, but treat the expiry as a hard date - we send the renewal quote about two months ahead so it is never a surprise.

Q. Will my staff notice anything on the day you install it?

Very little. There is a short gap while your internet line is moved across to the new unit, done before opening or after closing, and after that the visible changes are small - a block page on certain sites, and a one-time sign-in so each person's rules follow them to any desk. On day one we keep the filtering deliberately loose and tighten it over the following week, because blocking something the accounts team genuinely needs is the quickest way to make everyone resent a new firewall. Do warn us in advance about odd software; old accounting packages and machine-control PCs sometimes need a rule written specially for them.

Q. We already have a firewall from another brand and it still works. Why change now?

Very often you should not, and we will say so. Keep it if it is still in support, still receiving updates and still comfortable with your line speed. The reasons that do justify a change are specific: the model has gone end-of-life so no firmware arrives any more, your internet is now faster than the box can inspect, staff numbers have doubled, or the renewal on the old brand costs more than a new appliance with a fresh bundle. Look up the end-of-support date on your current model - plenty of offices around Kodalia are running one that quietly stopped getting updates two years ago.

Q. We have eleven shops - do I need one of these in every shop?

Yes, one at each shop, but they need not all be the same size or the same price. A small outlet with four billing counters runs happily on an entry-level SonicWALL TZ unit, while the head office, where everything comes together, takes the larger NSa. What the shops share is the rulebook and the licence, so a website blocked at head office is blocked at shop eleven without anyone driving there. Cost-wise the shop units are the cheap part; the head-office box and the yearly subscriptions are where the money actually sits.

Q. How does it scan a file for viruses without holding up the traffic?

It reads the data as it streams past instead of collecting the whole file into memory first, which is where older gateways lose both time and RAM (Reassembly-Free Deep Packet Inspection). With nothing sitting in a buffer there is no practical file-size limit, and thousands of connections can be checked side by side. Day to day that is why downloads and browsing feel ordinary with scanning switched on. The one place you will notice a pause is a genuinely unknown attachment being sent up to the cloud test-room, which adds a few seconds.

💡 Engineering Fact: Your manager gets manager-level internet access from any desk in the building because the firewall reads who signed in to Windows and applies rules to the person rather than to the machine (Single Sign-On).
