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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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 UTM Firewall Appliance for Branch and Head Office Sizing, Licensing & Onsite Support near Dutta Bagan

How much of your own network can you actually see from where you sit? For an owner running four outlets the honest answer is usually none of it: every shop has its own router, its own password and its own problem. Put a SonicWALL unit at each site and they all report into one dashboard, so the outlet and the warehouse appear on the same screen (Network Security Manager). Opening a fifth shop then becomes a form to fill in rather than a trip out of town.

🧭 SonicWALL UTM Firewall Appliance for Branch and Head Office Supply, Setup and Support at multi-branch offices

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

Head office finds out a branch is down when the branch manager rings, which is usually well after the customers noticed. Every appliance across Kolkata reports into one cloud console, so you can see which site is offline, which line is flapping and which firmware is behind, from a browser anywhere. A rule change is written once and pushed to all sites instead of typed out eleven times. Reports for the whole network arrive on schedule rather than being assembled by hand (Network Security Manager).

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.

🔑 Why Businesses Pick SonicWALL UTM Firewall Appliance for Branch and Head Office when budgets are tight

Connecting four or five branches across Kolkata to head office used to mean a leased line to each one, which most businesses could never justify. Ordinary broadband at every site, joined by encrypted tunnels through these appliances, gives you a single network for a small fraction of that. Staff at a depot open the same software they would open at head office, at whatever speed the local line allows. Adding the sixth site later is an afternoon's work, not a fresh project.

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 Dutta Bagan usually find the licence conversation more useful than the hardware one.

Depots and Godowns on Whatever Connection the Town Offers

A sweets and namkeen chain with fourteen outlets across Kolkata was opening two more before the festival season and had nobody free to travel. We registered both appliances here, couriered them out, and the shop staff plugged them into power and the broadband socket. Each unit pulled down its own rules, its guest Wi-Fi settings and the tunnel back to head office without an engineer on site. The second shop was billing on its opening morning, which had not happened with the previous three openings.

🛡️ SUPPORT ONCE THE INVOICE IS SETTLED

How We Plan a Firewall Rollout

A rollout across many branches is a logistics job as much as a technical one. Boxes are staged and pre-registered at our bench, shipped to each outlet, and brought online by the local manager plugging in two cables while an engineer watches the console. For a chain spread across Kolkata, that removes most of the travel and nearly all of the guesswork.

Here is the work we take on, all of it quoted before anyone starts:

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

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

▪Yearly Support Contracts with Agreed Response Times

▪Supply, Configuration and Go-Live of the Appliance

*Terms: engineer hours, travel and any parts fitted are invoiced under a private service agreement that stands apart from the product warranty.*

💡 Engineering Fact: That inspection has one visible side effect: browsers complain about certificates. Installing the firewall's own certificate on office machines during setup is a ten-minute job, and skipping it earns you a week of complaints.

📚 Ranges Sorted by Office Size for offices in Dutta Bagan

Compare the branch boxes against the head office models here:

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.

🔹 WIFI BUILT IN

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

🔹 COMMON MISTAKE

Sizing by staff count alone. Count the cameras, IP phones and card machines too - every one of them holds connections open all day.

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.

🔹 TWO POWER FEEDS

Fit the second supply and run it from another circuit. The day an electrician isolates one board, the network stays up.

🔹 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.

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.

🔹 PORT SPEEDS

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

🔹 AIRFLOW

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

🔹 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.

🔹 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.

🔹 SETUP

Nobody technical travels. The unit is registered before it leaves us and fetches its own configuration the first time it is switched on (Zero-Touch Deployment).

🔹 IF THE LINE DROPS

A second broadband connection, or a 4G or 5G dongle, carries that branch until the main link comes back.

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.

🔹 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.

🔹 PLANNING

Signal is eaten by brick walls, lift shafts and steel racking, so units get placed by the building's layout rather than by floor area.

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.

🔹 BETWEEN BUILDINGS

Copper stops being useful at about ninety metres. Past that the uplink goes on fibre, and these units take fibre directly.

🔹 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).

🔹 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.

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.

🔹 WHEN NOT TO BOTHER

If everyone works in one building and nobody travels, put the money into the firewall instead.

🔹 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.

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.

🔹 WHO IT SUITS

Retail chains, franchise groups, NBFCs with branch offices, and hospital groups running four or five units across Kolkata.

🔹 ALERTS

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

🔹 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.

🔹 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.

🔹 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.

🔹 AUDITS

Show an assessor a lapsed subscription and it goes straight into the report as a finding, whatever the firewall itself is doing.

🧮 Key Figures Every Buyer Should Check for larger offices

Redundancy comes in layers and you can buy them one at a time. A second internet connection is the cheapest, a mobile modem behind it is cheaper still, and a paired second appliance covers the unit itself failing. Rack models take two power supplies, which matters in buildings where the generator changeover is not gentle.

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.

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

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

🔹 The chip insideMulti-core system-on-chip running SonicOS 7

🔹 Encrypted site scanningTLS 1.3 inspection with hardware acceleration (DPI-SSL)

🔹 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

🔹 Brand-new threatsLive memory inspection plus the Capture ATP cloud sandbox (RTDMI)

How These Units Are Built and Tested

SonicWALL builds this range for organisations whose people are spread over many small sites rather than gathered in one building. The same operating system runs on a desktop unit in a single shop and on a rack appliance at head office, so a policy written once can be applied everywhere without translation.

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).

🗒️ Engineer Notes From Real Installations for demanding workloads

Spend the extra hour joining the firewall to your Windows login system at installation, even if nobody asked for it. Once rules and reports carry a person's name instead of an address, every argument about who did what stops being a debate. I put the agent on a member server rather than the area controller, using an account that can only read, which keeps your IT team and your auditor equally comfortable.

“We already have antivirus on every computer” covers the computers. The weighing machine, the barcode printer, the camera recorder and the visitor's phone cannot run antivirus, and they all sit on the same network.

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.

💡 Engineering Fact: Zoom, YouTube and your banking site all look identical from outside - encrypted traffic on the same port. The firewall recognises them by how each one talks, which is how a video call gets priority while streaming gets capped.

✅ How It Performs on a Normal Working Day when the office is busiest

CLEAR ADVANTAGES - IN PLAIN WORDS

COSTS BEYOND THE QUOTE SPELLED OUT UPFRONT

✓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).

—Hardware faults are settled under the manufacturer's warranty. We can raise the case and chase it, but the replacement timeline belongs to them, not to us.

✓Stock figures that reach head office a day late are usually a tunnel problem rather than a software one; every shop links back over one encrypted connection (site-to-site IPsec).

—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.

✓One click on a convincing invoice page is how most incidents begin; fake payment pages and spoofed download sites are blocked before the click matters (content filtering).

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

✓An ageing core switch and a new 10G uplink can end on the same appliance, so the network does not have to be replaced in one go (RJ45, 2.5GbE and SFP+ on larger models).

—There is no fail-open relay inside these units, so a failed appliance means a dead link rather than one that keeps passing traffic. Where a production line cannot tolerate that, budget for a second unit as a failover pair instead of assuming a bypass exists.

✓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).

—Turning on full inspection cuts the headline throughput figure. Size the model against the traffic you actually intend to scan, or the first busy morning will show it up.

💡 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.

🔧 Configuration & Testing - The Plan for small and mid-sized teams

🔹Add the serial number to the cloud console before the box is couriered to a branch, whether that branch is across Kolkata or three states away, so staff there only have to connect power and the internet cable.
🔹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.

🛠️ Workflow Setup

On the day itself the box goes in, power comes off two separate points where the room allows, and your line is shifted over from the old router. That old one stays wired for the twenty minutes it takes to be sure.

⚠️ Pitfalls to Avoid

Turning on every scanning feature at once on day one guarantees complaints. Bring them up in stages and give the office time to get used to each one.

🔌 Guidelines & Sizing

Insist on solid copper Cat6 with the maker's marking printed on the jacket. The cheap copper-clad aluminium sold under the same name heats up, loses signal over distance, and produces faults everyone blames on the provider.

📈 Upgrade Triggers

Half the staff now work from home part of the week through a remote desktop port that was opened in a hurry and has never been closed since.

Frequently Asked Questions

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.

Q. 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.

Q. 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 Dutta Bagan before quoting and give you the honest number.

Q. 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.

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.

💡 Engineering Fact: A reply from a website is allowed back in because the firewall remembers you asked the question. It holds a live table of every conversation in fast memory, and anything arriving that answers a question nobody asked is quietly discarded.
