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.

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.

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.

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.

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.

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.

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.

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.

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.

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 Kolkata 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.

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

Does it stop staff copying files onto a pen drive?

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

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

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

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.

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

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 Kolkata.

📞 Sizing, Licensing and Ordering SonicWALL UTM Firewall Appliance for Branch and Head Office close to Kolkata

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

Your ERP vendor wants remote access, your CCTV company wants remote access, and right now both hold the same password as your accountant. Each can instead be given an encrypted login that reaches exactly one machine on one port, with a second check at sign-in and a record of every session. Access can be switched on for the afternoon and off again by evening. That is a far smaller opening than the remote-desktop port most small offices in Kolkata leave facing the internet.

The security box in your rack still shows a green light, which is the most misleading thing about it. Once the subscription lapsed it stopped receiving new threat information, and it was never built to look inside the encrypted traffic that now carries almost everything. We read the old rules, rebuild only the ones still in use on a current SonicWALLUTM Firewall Appliance for Branch and Head Office, and switch over in the evening at your office in Kolkata. The old unit stays racked and powered off for a week in case anybody misses something.

👍 Why Owners Stop Worrying About This close to Kolkata

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

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 Kolkata - 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.

Delivered on site or remotely, with rates agreed in advance:

▪Testing Unknown Files Before They Reach Staff (Capture ATP)

▪Keeping Guest WiFi, Cameras and Billing Apart (VLAN Zones)

▪Access Point and Managed Switch Setup from One Console

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

*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: Post a branch box to a town where you have nobody technical and it still works. On first power-up it calls home, proves which unit it is, downloads its settings and is carrying traffic before the local staff finish their tea.

🗂️ Product and Licence Line-Up near Kolkata

Included accessories are marked, so nothing surprises you at delivery:

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.

🔹 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.

🔹 WHEN YOU GROW

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

🔹 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.

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.

🔹 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.

🔹 IF IT FAILS

Keep a matched second unit powered beside it. The changeover takes a fraction of a second and a phone call does not drop (High Availability pair).

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.

🔹 NOISE

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

🔹 WHO BUYS THIS

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

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.

🔹 JOINING SITES

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

🔹 IF THE LINE DROPS

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

🔹 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.

🔹 MANAGED FROM

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

🔹 THE PROBLEM IT SOLVES

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

🔹 VISITORS

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

Managed Switches on the Same Console as the Firewall

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

🔹 SEPARATE LANES

A camera recorder and a staff laptop can share cabling and still be unable to see each other, which is what setting up VLANs properly buys you.

🔹 ONE LOGIN

The switch shows up in the same management console as the firewall, so ports and security rules are dealt with together.

🔹 POWER OVER THE CABLE

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

Cloud Edge: Office Access for Staff Working from Home

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

🔹 HOW IT DIFFERS

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

🔹 SIGNING IN

People use the office credentials they already know, and a second check on their phone means a stolen password on its own is not enough.

🔹 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.

🔹 SETTINGS BACKUP

Configurations are held in the cloud, so a replacement unit at a distant branch is rebuilt from the last known-good copy.

🔹 ONE CHANGE, EVERY SITE

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

🔹 WHAT IT'S FOR

Companies with several sites, where logging into each firewall separately has stopped being realistic.

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.

🔹 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.

🔹 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.

🧠 Questions Customers Ask Us Most throughout Kolkata

If you are buying a pair for high availability, make sure both units are registered together and the licensing is associated correctly, or the standby will come up without its protection services running. Test the failover once in a planned window and note how long a live call takes to come back. A pair nobody has ever tested is an assumption, not a plan.

The router that came with your connection belongs, in every practical sense, to the internet company: they set the password, they update it when they feel like it, and it knows nothing about who in your office did what.

A security box bought around 2015 will still boot happily. Its threat feed stopped the day the licence did, and its processor was never designed for traffic that is now almost entirely encrypted.

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

📃 Feature List and Technical Detail around Kolkata

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.

SonicWALL Quality Control and Field Return Handling

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.

🏢 Configuration & Testing - Explained Simply anywhere in Kolkata

🔹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.

Next the unit is registered and licensed in your name and your rules are loaded before it leaves us. That takes a day or so at our end and saves a couple of hours at yours.

⚠️ 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.

📈 Upgrade Triggers

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.

🔍 Behaviour on a Slow Internet Line close to Kolkata

Two branch links watched for a week, one of them a shaky broadband line.

WHAT YOU GET FOR THE MONEY - THE SHORT VERSION

REAL LIMITS WITHOUT THE SALES PITCH

✓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).

—Branch VPN speed is capped by whatever upload your local line delivers. No appliance can create bandwidth the ISP is not providing.

✓Running thirty sites the way you ran three stops working around site number six; head office sees every outlet in one list instead of ringing each manager (Network Security Manager).

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

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

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

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

—Zero-touch rollout still needs a live internet connection at the branch and the right serial registered in the portal. Get either wrong and the box sits there blinking.

✓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).

—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: 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.

Frequently Asked Questions

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. 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. 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. 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.

Q. 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.

💡 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.

🌐 Industries We Support around Kolkata

📍 Kolkata

Securing a massive commercial or residential footprint across the historic capital lanes of Kolkata requires structural component selections calibrated for intense day-to-day ground realities. As the primary transport, retail, and institutional hub of West Bengal, properties across this sprawling metro experience heavy foot traffic, sudden voltage fluctuations, and harsh seasonal monsoon weather shifts that quickly degrade cheap standalone security cameras.

Deploying standard UTM Firewall Appliance for Branch and Head Office options from SonicWALL provides local storefronts, large-scale warehouses, corporate workspaces, and family residences with a hardened monitoring grid engineered to hold steady video data throughput round the clock. This high-resolution surveillance network minimizes blind zones elegantly across complex layout coordinates, delivering trace-free structured data cabling protection that keeps you fully informed of real-time movement.

Whether you are coordinating multi-channel recording loops inside dense market hubs or tracking private entries off busy transit junctions in Kolkata, standardizing your security infrastructure on a machine-tested framework eliminates technical vulnerabilities, ensuring your data retention logs remain locked safely on local drives.
