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.

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.

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.

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.

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 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.

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 Central before quoting and give you the honest number.

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.

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.

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.

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 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.

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.

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.

Genuine SonicWALL TZ & NSa Firewall Installation in Central

Buying the biggest model the budget allows is the mistake I meet most often, and it is a costly one. A TZ carries a busy branch comfortably, an NSa suits a head office with servers and staff dialling in from home, and NSsp is data-centre kit that a forty-seat firm has no business paying for. What really decides it is how many people are online together, whether you want encrypted traffic inspected, and how many branch tunnels you need. Give me those three answers and the model picks itself.

Engineer with a laptop working at an open network cabinet during setup in Kolkata

Somebody switched the scanning off years ago because the network slowed to a crawl, and nobody has switched it back on since. This appliance examines traffic as it streams past instead of holding whole files in memory first, which is why the checks can stay on through your busiest hour. Large downloads, backups and cloud accounting sessions all keep moving. It is a different way of reading traffic, and it is the reason a modest unit inspects far more than you would expect (Reassembly-Free Deep Packet Inspection).

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).

👍 Why Owners Stop Worrying About This close to Central

The awkward moment in most audits is the question about which staff can open the accounting system, and from which machines. Because rules are written against your office logins, the answer comes out of the console as a list of names rather than a promise from memory. Reports can be scheduled so the evidence already exists before anyone asks for it. Firms dealing with banks, exporters and listed customers get asked this far more often than they expect.

Very few businesses stay the size they were when they bought their last firewall. One operating system covers every model, so whoever learns the branch box can already work the rack appliance at head office, and the configuration travels up with you. Extra branches, remote staff and a second internet line become settings rather than new equipment. You are buying something to grow into instead of a box you will outgrow.

Lending Branches Where Every Action Needs a Name on It

A packaging printer with a design studio in Kolkata and a plant an hour away moved artwork files of several gigabytes between the two, and every transfer strangled everything else on the line. The new gateway gives file transfers whatever bandwidth is spare but never the share reserved for calls, mail and the ERP. Two internet lines are now used together, with the heavy traffic pushed onto the cheaper one. Nobody in accounts can tell any more when a job is being sent.

🛡️ MULTI-BRANCH DEPLOYMENT PRACTICE

Standards We Hold Ourselves to in the Rack

It is worth being blunt about who we are: an independent supplier and integrator, not the manufacturer's helpdesk. Our team racks the unit, cables it into your switches, and proves the standby really does take over by unplugging the primary in front of you rather than quoting a datasheet line. If a fault turns out to be hardware, we open the warranty case with SonicWALL and keep chasing it, though the replacement clock is theirs.

A short menu of what customers ask us to take off their hands:

▪Yearly Support Contracts with Agreed Response Times

▪Moving Off Your Old Firewall Without Downtime

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

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

*For clarity: licence renewals are billed at the applicable rate for the term you choose, and our handling of that paperwork is itself a chargeable service.*

💡 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).

🗂️ Pick the Right Variant Without Overspending in and around Central

Here is what each model handles, in numbers you can compare:

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.

🔹 SPEED

Scanning happens on the same multi-core chip that moves the traffic, so switching virus and web filtering on does not turn browsing into a crawl.

🔹 POWER DRAW

Modest enough that a small UPS carries the firewall, the modem and the switch straight through a cut.

🔹 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.

🔹 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.

🔹 SIZE

One rack unit in a standard 19-inch cabinet, with airflow running front to back, so the rear of the unit must never be boxed in.

🔹 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).

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.

🔹 WHO BUYS THIS

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

🔹 NOISE

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

🔹 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.

🔹 IF A UNIT DIES

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

🔹 REPORTING

Head office can see each branch's uptime and how its line is performing, which ends the argument about whose internet is at fault.

🔹 WHAT STAFF NOTICE

Nothing, ideally. Billing, the shared drive and the ERP screen open at the same pace as they do at head office.

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.

🔹 WHERE IT SUITS

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

🔹 WALKING AND TALKING

The handover from one unit to the next is quick enough that a call carries on while somebody walks from the store room back to the billing counter.

🔹 MANAGED FROM

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

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.

🔹 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.

🔹 LOST LAPTOP

One click ends that person's access. Nobody has to change a shared VPN password and then explain it to forty people.

🔹 TEMPORARY PEOPLE

A software vendor can be let in to one machine for a week, with the access closing on its own rather than being forgotten.

🔹 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.

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.

🔹 REPORTS

Monthly summaries of what was blocked and where the day's bandwidth went, in a shape a director will actually read.

🔹 WHAT IT WILL NOT DO

It does not replace somebody reading the reports. The console tells you; it does not decide for you.

🔹 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.

🔹 HOW WE TRACK IT

Microtech Solutions holds the expiry dates and raises them early, so nobody is chasing a renewal on the last working afternoon.

🔹 HARDWARE COVER

How fast a failed unit is replaced depends on the support level you chose. Decide that on a calm day, not on the morning it dies.

🔹 MULTI-YEAR TERMS

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

⚙️ SYSTEM EVALUATION & CHECKLIST

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

🛠️ Workflow Setup

Internal lanes come next, accounts, guest WiFi, cameras and production kept apart, and computers pick up their new settings by themselves. Nobody walks desk to desk.

⚠️ Pitfalls to Avoid

Never leave guests and staff sharing a WiFi password. Whoever printed it on the menu card has effectively given the accounts server a public entrance.

🔌 Guidelines & Sizing

Use a patch panel and cut the leads to the length the run actually needs. A cabinet stuffed with three-metre cables is impossible to trace, and tracing is what you end up paying for at midnight.

📈 Upgrade Triggers

Every new outlet costs an engineer a full day on site to set up, and four more are opening this year.

🛠️ Mounting Access Points and Getting the PoE Sums Right

Branch sites rarely have a proper rack, so these notes assume a wall cabinet, a counter and one plug point in Central.

🧰 User Training & Handover - What to Expect near Central

🔹Install the single sign-on agent on an ordinary member server using a read-only service account, then confirm that a shared counter machine shows the correct user name in the log before you write any person-based rules.
🔹Give the appliance its own management address on a separate VLAN and turn administration off from the internet side completely; reach it over the VPN when you are away from the office.
🔹Point the failover probes at something outside your provider's network, such as a public DNS address. Probing the provider's own gateway means a dead upstream link still looks perfectly healthy.

🧠 Advice We Give Before Anyone Buys throughout Kolkata

Roll out encrypted-traffic inspection one department at a time and keep an exclusion list from day one. Banking portals, health sites and a handful of applications that refuse to work through inspection all need listing, and that is normal rather than a failure. Done gradually you will field three support calls instead of thirty.

Buying web filtering from one vendor, VPN from another and antivirus from a third leaves three renewal dates in the diary, three consoles to learn, and nobody to call when they disagree with each other.

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.

💡 Engineering Fact: Generator changeover is harder on network equipment than the power cut itself. The spike as the load transfers is a common reason a power supply gives up, and an online UPS in between is the cheapest insurance in the room.

📃 How Much It Handles Before It Slows Down around Central

The range is easier to understand than the model numbers suggest. TZ units are desktop boxes for a shop, a clinic or a branch of twenty to fifty people; NSa models are rack appliances for a head office or a busy campus; NSsp sits above that for data centre work. Most businesses we quote in Kolkata end up with a TZ at each branch and one NSa at head office, and that combination behaves as a single network.

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.

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

🔌 Second power supplyOptional on smaller rack models, standard and hot-swappable on the large ones

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

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

🔹 Temperature it toleratesRated for 0°C to 40°C ambient (32°F to 104°F)

Signed Firmware and Secure Startup: SonicWALL Practice

Nothing waits in a queue while a scanner collects a whole file first, so a large drawing or a software installer arrives at the pace your line allows and is still checked on the way in. You never have to set a maximum file size and hope nothing bigger turns up, because traffic is read as it flows (Reassembly-Free Deep Packet Inspection).

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).

WHERE IT SHINES - THE SHORT VERSION

ONGOING EFFORT NEEDED WITHOUT THE SALES PITCH

✓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.

—Central management and cloud reporting need a stable outbound line. At a site with a flaky connection, expect holes in the dashboard rather than a full picture.

✓A salesman on hotel WiFi can reach the office system with nothing installed on his laptop and no port left open to the whole internet (SSL VPN with a second login check).

—Renewal is not a small line item. Budget for it every year or two alongside the hardware, because a firewall with an expired bundle is not far off an expensive router.

✓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).

—Running BGP or OSPF is serious network work. Bring in someone who has done a cutover before instead of learning on a live site.

✓Redundancy is usually the first thing struck off a quotation on price. The second unit is licensed as a high-availability partner rather than as a full second appliance, which is what keeps the pair affordable to own.

—Without a UPS behind it, every power cut becomes an unplanned restart. Repeat that twice a day through a bad week and you are gambling with the hardware, not just the uptime.

✓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).

—In-depth logs fill internal storage if rotation is left at default and nothing is being shipped off the device.

💡 Engineering Fact: Your whole office looks like one address from the outside, with dozens of machines sharing it. That is also why a camera recorder plugged straight into the internet, with no firewall in front, gets found by automated scanners within hours.

Frequently Asked Questions

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

Q. 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.

Q. 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.

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. 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.

💡 Engineering Fact: In a two-firewall setup the standby is kept fully briefed on every open connection, which is why a takeover finishes in a fraction of a second and the call in progress carries on. The pair gossip over their own cable, not the office switch.
