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.

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.

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.

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.

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 Baranagar are running one that quietly stopped getting updates two years ago.

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.

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.

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.

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.

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.

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 Baranagar before quoting and give you the honest number.

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.

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.

SonicWALL UTM Firewall Appliance for Branch and Head Office Sizing, Licensing & Onsite Support near Baranagar

Festival shutdown week is my favourite time to swap a firewall, because the floor is quiet and nobody loses a day of billing. It is also the week I discover how many sites are running on one unprotected broadband line, with the modem balanced on a UPS that stopped holding charge two years ago. Voltage swings and dusty back rooms finish off cheap routers; a properly mounted appliance on clean power simply keeps going. We plan those changeovers around your calendar, anywhere in Kolkata.

💼 SonicWALL Deployment, Migration and Handover in Baranagar

Underside label of the appliance showing its serial number and model name

An invoice arrives from a supplier you deal with every week, and the attachment is new enough that no scanner recognises it yet. Rather than guess, the firewall holds that file and opens it inside a test room in the cloud, releasing it only once it has behaved itself. Nothing lands in the accounts mailbox until the verdict comes back. For offices in Kolkata that pay against emailed attachments daily, that short pause is worth far more than it costs (Capture ATP).

Three people share the counter machine on rotation, so the network log tells you what the computer did but never who did it. Joining the firewall to your existing office logins means each rule and each line of the report carries a name instead of an address. A temporary hand gets the temporary set of permissions, wherever he happens to sit. When he leaves, one account is disabled and every branch honours it within minutes (Single Sign-On with Active Directory).

🤝 What You Get That Cheaper Options Skip in Baranagar

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 Baranagar 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:

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

▪Access Point and Managed Switch Setup from One Console

▪Automatic Switching between Two Internet Lines (SD-WAN)

▪Sending a Pre-Set Box to a New Branch (Zero-Touch)

*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: 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).

See What Support Covers →

🧾 Available Options and Typical Fit for first-time buyers

Ports, speeds and bundle options for every size are set out below:

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.

🔹 BEST FOR

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

🔹 TWO INTERNET LINES

Fibre and a broadband backup stay plugged in together and the box quietly uses whichever one is behaving (Secure SD-WAN).

🔹 SOCKETS

Six to ten network points, some of them 2.5-gigabit, with a fibre slot on the larger models for a leased line.

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.

🔹 SEVERAL ISP LINES

More than one connection terminates on the same unit and it decides what travels where (BGP, OSPF and dynamic SD-WAN routing).

🔹 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).

🔹 FIBRE UPLINKS

Ten-gigabit fibre ports land straight on the core switch, which keeps a media converter off the list of things that can fail (SFP+).

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.

🔹 AIRFLOW

Fan trays are changed without a shutdown, and the front-to-back path has to stay clear - no cartons leaning against the cabinet.

🔹 WHO BUYS THIS

Hosting providers, university campuses and large manufacturers running a proper data centre floor of their own.

🔹 MEMORY-LEVEL CHECKS

Unknown files are watched while they actually run in memory, which catches the tricks written to fool an ordinary scanner (RTDMI).

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.

🔹 IF A UNIT DIES

Courier a replacement. It collects the same configuration by itself, so the branch is usually back on the same day.

🔹 BUILD

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

🔹 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.

🔹 MANAGED FROM

The firewall itself acts as the wireless controller, so there is no second box and no second console to log into.

🔹 VISITORS

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

🔹 CROWDED ROOMS

WiFi 6 units are designed to serve many devices politely at the same moment, and that is what a full training room actually needs.

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.

🔹 FINDING THE FAULT

When one machine floods the network, the guilty port is named on screen and closed from there, instead of by pulling cables one at a time.

🔹 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.

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.

🔹 WHAT IT COSTS

Priced by the person by the month, so a team of six is paid for as six and not as the entire company.

🔹 HOW IT DIFFERS

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

🔹 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.

🔹 ALERTS

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

🔹 AUDIT TRAIL

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

🔹 ONE CHANGE, EVERY SITE

A new blocking rule reaches twenty branches at once, instead of being typed twenty times with the twentieth forgotten.

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.

🔹 WHEN IT EXPIRES

No alarm sounds and nothing goes dark. The unit simply stops learning about anything new while everyone assumes it is still working.

🔹 MULTI-YEAR TERMS

Paying for three years at once holds the price still and removes two more rounds of quotations, approvals and reminder calls.

🔹 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.

🛠️ Workflow Setup

Then everything is tried in front of you: browsing, email, Tally, the card machine, the camera app on your phone, a call over the internet. That takes roughly an hour, and your staff do the testing rather than us.

⚠️ Pitfalls to Avoid

Do not point rules at anything and everything just to get the office working before lunch. Temporary rules of that kind outlive the engineer who wrote them.

🔌 Guidelines & Sizing

Register the serial number in your own company's name rather than the integrator's. If you change vendors later, a unit sitting in somebody else's account is a genuine headache to move.

📈 Upgrade Triggers

Your insurer's renewal form asks whether internet traffic is filtered and logged, and nobody in the office knows what to write.

BENEFITS YOU WILL NOTICE SUMMED UP

COMMON COMPLAINTS - BEFORE YOU SIGN

✓Nobody has to remember to press update: the known-bad list refreshes on its own schedule, so cover does not quietly age between service visits.

—Somebody has to own the rule list. Without that, the temporary allow-rules added before last Diwali are still open and nobody remembers who asked for them.

✓Three logins for a firewall, a switch stack and a wireless controller become one, because the switches are configured from the same screen (SonicOS switch management).

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

✓Large engineering drawings and installer files are not skipped for being too big, because there is no size cut-off on the scan (RFDPI).

—Reading inside encrypted sites means pushing a certificate onto every company machine first. Phones brought from home will keep throwing warnings until somebody decides how to handle them.

✓An older box simply passed https pages along unread, and that is precisely where the trouble hides today; those sessions are opened and checked, with banking and health sites left alone by policy (TLS deep inspection).

—Sandboxing, filtering and threat feeds sit inside a subscription bundle. Let it lapse and the box carries on routing, but the checks you bought it for quietly stop.

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

—Real redundancy needs two identical appliances, not one box and a spare in the cupboard. The second unit is a second buy, and its licence position needs confirming before you order.

💡 Engineering Fact: A cheap router glances at the first few pieces of a download and waves the rest through. This one reads the file all the way from first byte to last as it arrives, which is why a virus split across several packets still gets caught (RFDPI).

⚙️ Site Survey & Planning - A Timeline around Baranagar

🔹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 Baranagar - a unit downloading its first threat update while thirty people wait is an avoidable delay.
🔹Add up the wattage of the access points before hanging them off a switch. A power budget that looks generous on paper runs out quickly once ceiling units and a couple of cameras are drawing from it.

🗒️ Capacity, Limits and Sizing Guide in Baranagar

Throughput is published several ways and only one of them matters to you. Ask for the figure measured with intrusion prevention and encrypted inspection both running, because that is the state the appliance will actually work in day to day. The larger number on the front of a brochure is measured with almost everything switched off.

Port layout decides what has to change in your rack. Copper gigabit ports handle desks and switch links, some models bring power-over-Ethernet ports for access points and cameras, and fibre cages are there when the core switch or the leased line handoff needs them. A USB socket takes a mobile modem for backup internet.

🏆 CORE PARAMETER🔹 Shapes it comes inFanless desktop TZ, 1U rack NSa, 2U rack NSa and NSsp

How to Tell a Grey-Market Box From a Genuine One in Baranagar

Nobody in your office receives an attachment the world has not seen before on trust alone; it is opened in a sealed test room in the cloud first and released only when the verdict comes back. Files are also watched while they run in live memory, which is how malware written to look harmless to an ordinary scanner gets caught (Real-Time Deep Memory Inspection).

Most infections now ride inside encrypted pages, so those pages get opened and read - and you decide which categories, banking and health among them, are left untouched. On the larger models that checking runs in hardware, so you can keep it switched on through the busiest hours instead of turning it off to buy speed.

👀 Common Failures and How We Fix Them in Baranagar

A mobile modem on the back of the unit is only a backup if the SIM has balance and validity. I have reached sites in Kolkata where the failover worked perfectly and the data pack had expired eight months earlier. Put the recharge on the same reminder as the licence renewal, and test the switchover once a quarter.

Upgrading to a bigger internet line rarely fixes slowness, because the line was rarely the problem. A gateway that shows which application is eating the connection usually costs less than a single year of the faster plan.

An open-source firewall built by a talented employee runs beautifully until he changes jobs. After that nobody can log in, nobody knows what the rules mean, and no vendor is obliged to ship you a replacement.

💡 Engineering Fact: Guest WiFi cannot reach your accounting server, and the reason is not the password. The two sit in separate zones with no rule joining them, so nothing crosses unless someone deliberately writes that rule.

Frequently Asked Questions

Q. 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.

Q. 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.

Q. 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.

Q. 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.

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: Padlock icons stopped meaning safe a long while ago - the padlock only hides what is travelling. The firewall opens that envelope, reads what is inside and seals it again, doing the heavy maths in dedicated hardware so nobody notices the pause.
