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 Bankra.
✅ SonicWALL Deployment, Migration and Handover anywhere in Kolkata
An invoice arrives from a supplier you deal with every week, and the attachment is new enough that no scanner recognises it yet. Rather than guess, the firewall holds that file and opens it inside a test room in the cloud, releasing it only once it has behaved itself. Nothing lands in the accounts mailbox until the verdict comes back. For offices in Kolkata that pay against emailed attachments daily, that short pause is worth far more than it costs (Capture ATP).
Three people share the counter machine on rotation, so the network log tells you what the computer did but never who did it. Joining the firewall to your existing office logins means each rule and each line of the report carries a name instead of an address. A temporary hand gets the temporary set of permissions, wherever he happens to sit. When he leaves, one account is disabled and every branch honours it within minutes (Single Sign-On with Active Directory).
🧠 What 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
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:
▪A Standby Box So One Failure Does Not Stop Work
▪Supply, Configuration and Go-Live of the Appliance
▪Automatic Switching between Two Internet Lines (SD-WAN)
▪Keeping Guest WiFi, Cameras and Billing Apart (VLAN Zones)
*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: 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.
🧯 SOMETHING GOT IN
Files renamed overnight, or one machine behaving very strangely? Call before you pay anybody anything - we will read what the network can tell us and contain it first, for businesses in Bankra.
Ports, speeds and bundle options for every size are set out below:
TZ Desktop Firewalls for a Shop or Single Branch
The small box that sits on a shelf behind the counter and guards one or two internet lines. Right for a showroom, a clinic, a site office or any team of roughly five to fifty people.
🔹 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.
🔹 TWO INTERNET LINES
Fibre and a broadband backup stay plugged in together and the box quietly uses whichever one is behaving (Secure SD-WAN).
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.
🔹 WORKING PACE
Virus scanning, intrusion checks and encrypted-site inspection can all run together while the branch tunnels stay usable.
🔹 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.
🔹 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.
🔹 MEMORY-LEVEL CHECKS
Unknown files are watched while they actually run in memory, which catches the tricks written to fool an ordinary scanner (RTDMI).
🔹 WHO BUYS THIS
Hosting providers, university campuses and large manufacturers running a proper data centre floor of their own.
🔹 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.
🔹 IF THE LINE DROPS
A second broadband connection, or a 4G or 5G dongle, carries that branch until the main link comes back.
🔹 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.
🔹 VISITORS
Guests get their own name, their own login page and an expiry, kept well away from the machines running your accounts.
🔹 WHERE IT SUITS
Factory floors, hostels, showrooms with roaming billing tablets, and offices that have run out of desk network points.
🔹 CROWDED ROOMS
WiFi 6 units are designed to serve many devices politely at the same moment, and that is what a full training room actually needs.
Managed Switches on the Same Console as the Firewall
Switches that report to the same screen as the firewall, so ports, cameras and phones are handled from one login. For offices past the stage of stacking small unmanaged boxes under a desk.
🔹 CHANGING A DESK
Moving somebody from accounts to sales becomes a setting, not a trip to the rack with a screwdriver and a torch.
🔹 WHAT IT'S FOR
Replacing the chain of little unmanaged switches that has grown under the desks, one added per problem over five years.
🔹 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.
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.
🔹 WHAT IT'S FOR
The accounts person finishing a return from home, and the sales engineer who needs the price list while sitting in a client's office.
🔹 WHEN NOT TO BOTHER
If everyone works in one building and nobody travels, put the money into the firewall instead.
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.
🔹 WHAT IT WILL NOT DO
It does not replace somebody reading the reports. The console tells you; it does not decide for you.
🔹 WHAT IT'S FOR
Companies with several sites, where logging into each firewall separately has stopped being realistic.
🔹 AUDIT TRAIL
Every configuration change is recorded against a name and a time, which settles most arguments before they properly start.
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.
🔹 WHAT YOU ARE PAYING FOR
Not the metal box. You are paying for current threat information, category lists, and somebody to call when it misbehaves.
🔹 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.
🔹 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.

📋 Key Figures Every Buyer Should Check 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 to Tell a Grey-Market Box From a Genuine One in Bankra
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.
✉️ SUPPORT DESK
Coordinate custom hardware configurations, AMC maintenance contracts, and site engineering visits directly with authorized integration desks.
💡 Common Failures and How We Fix Them after years of site visits
A mobile modem on the back of the unit is only a backup if the SIM has balance and validity. I have reached sites in Kolkata where the failover worked perfectly and the data pack had expired eight months earlier. Put the recharge on the same reminder as the licence renewal, and test the switchover once a quarter.
Upgrading to a bigger internet line rarely fixes slowness, because the line was rarely the problem. A gateway that shows which application is eating the connection usually costs less than a single year of the faster plan.
An open-source firewall built by a talented employee runs beautifully until he changes jobs. After that nobody can log in, nobody knows what the rules mean, and no vendor is obliged to ship you a replacement.
💡 Engineering Fact: 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.

Go through these before the delivery date, not on the day an engineer is standing in your server room with a screwdriver.
🏢 Data Migration & Cutover - A Timeline around Bankra
🔹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.

BENEFITS YOU WILL NOTICE - FOR BUYERS
COMMON COMPLAINTS - A QUICK LIST
✓A separate wireless controller is one more box to buy, power and patch. The access points here register with the firewall and take their settings from it.
—Firmware upgrades drop live sessions for a moment. On a single appliance that means an after-hours window agreed with whoever works late.
✓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).
—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.
✓The eleven o'clock slowdown is rarely the internet line. The traffic report names the application eating it, and that one habit can be held back without touching anyone's work.
—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.
✓The audit question - who reached what, and when - is answered from the reports instead of from memory.
—Branch VPN speed is capped by whatever upload your local line delivers. No appliance can create bandwidth the ISP is not providing.
✓When the fibre drops in the middle of billing, the second line picks the traffic up on its own rather than waiting for someone to notice (Secure SD-WAN).
—The smaller desktop models run off an external adapter. If that adapter fails, the site stays down until a replacement physically arrives.
💡 Engineering Fact: Firewall firmware is not a phone update you can put off for two years. Fixes for holes that are already being exploited arrive in it, and a unit three versions behind is doing rather less than its owner believes.

🛠️ Workflow Setup
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.
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 Bankra before quoting and give you the honest number.
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. 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.
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. 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.
💡 Engineering Fact: Some malware behaves perfectly while it is being scanned and only turns nasty half an hour later. To catch that habit, unknown files are run in a controlled patch of memory and watched for what they actually do (RTDMI).
