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.

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

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.

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.

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.

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.

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.

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 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.

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.

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 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.

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.

Multi-Site SonicWALL UTM Firewall Appliance for Branch and Head Office Deployment & SD-WAN in Basunagar

Guest WiFi in the waiting area, staff WiFi upstairs, card machines on their own lane and CCTV kept well away from all of it. That is four networks, and most places run them as four separate headaches with four sets of wires. When the access points and switches answer to the same firewall, you set that separation once and it holds everywhere, so a visitor gets internet without ever seeing the accounts server (VLANs from one console). We do this for clinics, showrooms and co-working floors around Basunagar.

✅ SonicWALL UTM Firewall Appliance for Branch and Head Office Supply, Setup and Support anywhere in Kolkata

Two broadband routers and the firewall placed side by side on a rack shelf

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.

🧠 What Changes in the First Month with a growing team

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.

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.

Plant Machinery That Should Never Meet the Open Internet

A fuel retailer with card-payment terminals standing unattended at several forecourts needed those terminals kept well away from the office computers at the same sites. Each forecourt now runs one appliance with the payment equipment in an isolated zone, reachable only by the payment processor's own connection. Staff machines, the camera recorder and the office printer sit in separate lanes on the same box. Head office pushed one policy change to every site last month in a single afternoon.

🛡️ CUTOVER PLANNING AND FALLBACK

Sizing Honestly, Even When It Costs Us the Sale

Dropping a SonicWALL appliance into a network that is already carrying live work begins with an inventory, not a toolkit. We write down what actually runs at your site in Basunagar - the Tally server, the biometric reader, the CCTV recorder, the second broadband line nobody documented - before a single rule is typed. Only then is a switchover slot agreed, usually after closing time, with a tested way back if something misbehaves.

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

▪A Standby Box So One Failure Does Not Stop Work

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

▪Access Point and Managed Switch Setup from One Console

*Notice: charges for cabling, commissioning and policy review are shared before we start. We do not act as the vendor's support line.*

💡 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.

🏷️ Product and Licence Line-Up near Basunagar

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.

🔹 TWO INTERNET LINES

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

🔹 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.

🔹 SIZE AND NOISE

Book-sized, fanless on the smaller models, quiet enough to live on a reception shelf without anyone noticing it is there.

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.

🔹 CHECK THIS FIRST

Cabinet depth and free rack units. More installations get delayed by a shallow cabinet than by anything technical.

🔹 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).

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.

🔹 WEIGHT

A two-person lift, on rails rated for the load. An appliance this heavy resting on cabinet ledges will sag and take its ports with it.

🔹 NOISE

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

🔹 LOGS ON BOARD

Internal SSDs hold traffic history on the appliance itself, so a question about last month does not need a separate log server.

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.

🔹 WHO IT SUITS

Franchise chains, multi-store retail and companies opening two or three locations a year in towns they have never staffed before.

🔹 BUILD

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

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.

🔹 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.

🔹 THE PROBLEM IT SOLVES

WiFi that is fine beside the cabin and useless at the other end of the same floor.

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).

🔹 WHAT IT'S FOR

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

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.

🔹 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.

🔹 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.

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.

🔹 FIRMWARE

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

🔹 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.

🔹 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.

🔹 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.

🔹 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.

💡 Engineer Notes From Real Installations after years of site visits

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: The clever part of that test is not the testing, it is the holding. The mail waits in the queue until a verdict comes back, so nobody has to be trusted to remember not to click.

Go through these before the delivery date, not on the day an engineer is standing in your server room with a screwdriver.

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

🔹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.
🔹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.

📋 Feature List and Technical Detail for small teams

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.

Management is a browser page on the unit itself, plus a cloud console for anyone running more than one site. Logs and reports can sit on the appliance for recent activity or be sent off it when you need months of history for an audit. Configuration exports are small files and should live somewhere other than the same building.

How These Units Are Built and Tested

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).

Hardware is specified for continuous operation in ordinary commercial premises. Compact models run without fans for quiet, dust-tolerant service at a counter or in a small office, while rack models offer redundant power and pairing for sites that cannot tolerate an outage.

🚦 How It Performs on a Normal Working Day in day-to-day use

CLEAR ADVANTAGES - FOR BUYERS

COSTS BEYOND THE QUOTE - A QUICK LIST

✓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.

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

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

—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.

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

—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.

✓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).

—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.

✓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.

💡 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).

⚠️ Pitfalls to Avoid

Never hang the firewall off the same strip as an air conditioner or a laser printer. The surge when either starts is enough to restart it, usually mid-morning.

🔌 Guidelines & Sizing

Have the rack and the incoming telecom line properly earthed before installation day. Most equipment written off as lightning damage in this country was really killed by a missing earth.

The last virus scare was cleaned up by rebuilding three machines over a weekend, and to this day nobody can explain how it got in.

Frequently Asked Questions

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 Basunagar 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. 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 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.

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: 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.
