Festival shutdown week is my favourite time to swap a firewall, because the floor is quiet and nobody loses a day of billing. It is also the week I discover how many sites are running on one unprotected broadband line, with the modem balanced on a UPS that stopped holding charge two years ago. Voltage swings and dusty back rooms finish off cheap routers; a properly mounted appliance on clean power simply keeps going. We plan those changeovers around your calendar, anywhere in Kolkata.
🏢 Sizing, Licensing and Ordering SonicWALL UTM Firewall Appliance for Branch and Head Office in and around Joygachi
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.
🎯 Good Reasons to Move Off Your Current Setup in and around Joygachi
Most protection still works by recognising something it has seen before, which is no help on the morning a brand-new variant reaches your accounts mailbox. This platform watches unfamiliar code while it runs in live memory, so behaviour gives it away even when no signature exists yet, and anything still unknown goes to a cloud test room before release. The practical effect is that your safety no longer depends on being late in the queue of victims. That is the part of the subscription we would argue hardest against dropping (Real-Time Deep Memory Inspection).
The real question with security hardware is not what it does on installation day but who answers the phone eleven months later. You get a named engineer, a stated response time and a replacement arrangement instead of a ticket number in a queue. Firmware updates are planned with you, in a window that suits your billing cycle, rather than pushed at random. For firms near Joygachi with no IT department of their own, that arrangement is usually why the equipment stays healthy.
Pharmacy and Grocery Counters Where Billing Cannot Stop
A formulation plant in an industrial estate near Joygachi had laboratory instruments running software the supplier stopped updating years ago, sitting on the same network as email and the internet. We fenced those machines into a zone that can talk only to the one server they report into, and nothing else. Office traffic, the plant network and the camera system now run in separate lanes through a single appliance. When the quality auditor asked how the instruments were protected, the answer was a rule list rather than a promise.
🛡️ LICENCE TRACKING AND RENEWAL DISCIPLINE
Switchover Night, and the Way Back
Licences are where firewall projects quietly fall over. We keep the expiry dates for the security bundle at every site, warn you well ahead of renewal, and spell out which checks stop working the day a subscription ends. Nobody gains from a customer finding out that on a Monday morning.
Everything below is chargeable and priced before we begin:
▪Supply, Configuration and Go-Live of the Appliance
▪Sending a Pre-Set Box to a New Branch (Zero-Touch)
▪Testing Unknown Files Before They Reach Staff (Capture ATP)
▪Yearly Support Contracts with Agreed Response Times
*Disclaimer: migrations, rule audits and branch rollouts are charged per job or under a contract. Hardware warranty claims continue to run through the manufacturer's channels.*
💡 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.
📦 NEW BRANCH, NO TRAVEL
A new outlet does not have to wait for an engineer's calendar. The unit is registered before it is couriered and the shop staff only have to plug it in - for openings anywhere near Joygachi.
📋 Complete List of What We Supply for first-time buyers
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.
🔹 WIFI BUILT IN
Several models carry their own wireless, which saves buying a separate access point in a one-room office.
🔹 SIZE AND NOISE
Book-sized, fanless on the smaller models, quiet enough to live on a reception shelf without anyone noticing it is there.
🔹 POWER DRAW
Modest enough that a small UPS carries the firewall, the modem and the switch straight through a cut.
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.
🔹 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.
🔹 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.
🔹 POWER
Both supplies come fitted. Feed them from separate circuits and one failed input turns into a log entry instead of an outage.
🔹 NOISE
Nobody enjoys sitting next to one of these. Plan for a real server room, not a cabin behind the accounts desk.
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.
🔹 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).
🔹 BUILD
Metal case, low power draw, and it copes with a dusty stores room far better than the plastic router the ISP left behind.
🔹 COST NOTE
A branch unit and its subscription usually work out below a leased line to the same location, which is the whole argument for SD-WAN.
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.
🔹 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.
🔹 THE PROBLEM IT SOLVES
WiFi that is fine beside the cabin and useless at the other end of the same floor.
🔹 WALKING AND TALKING
The handover from one unit to the next is quick enough that a call carries on while somebody walks from the store room back to the billing counter.
Managed 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.
🔹 WHAT IT'S FOR
Replacing the chain of little unmanaged switches that has grown under the desks, one added per problem over five years.
🔹 SUITS
Warehouses, hospitals and any premises where the camera count has quietly doubled since the cabling was first laid.
🔹 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.
🔹 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.
🔹 RECORDS
Who connected, when, and to which server - the report exists whether or not anybody ever asks to see it.
🔹 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.
🔹 SETTINGS BACKUP
Configurations are held in the cloud, so a replacement unit at a distant branch is rebuilt from the last known-good copy.
🔹 WHO IT SUITS
Retail chains, franchise groups, NBFCs with branch offices, and hospital groups running four or five units across Kolkata.
🔹 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.
🔹 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.
🔹 AUDITS
Show an assessor a lapsed subscription and it goes straight into the report as a finding, whatever the firewall itself is doing.

💬 Questions Customers Ask Us Most in and around Joygachi
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: 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.

🛠️ Workflow Setup
Then everything is tried in front of you: browsing, email, Tally, the card machine, the camera app on your phone, a call over the internet. That takes roughly an hour, and your staff do the testing rather than us.
⚠️ Pitfalls to Avoid
Do not point rules at anything and everything just to get the office working before lunch. Temporary rules of that kind outlive the engineer who wrote them.
🔌 Guidelines & Sizing
Register the serial number in your own company's name rather than the integrator's. If you change vendors later, a unit sitting in somebody else's account is a genuine headache to move.
📈 Upgrade Triggers
Your insurer's renewal form asks whether internet traffic is filtered and logged, and nobody in the office knows what to write.

WHAT YOU GET FOR THE MONEY AT A GLANCE
REAL LIMITS SET OUT PLAINLY
✓Opening a branch in a town where you know nobody used to mean sending an engineer for two days. The box is couriered instead and the shop manager plugs it in (Zero-Touch Deployment).
—In-depth logs fill internal storage if rotation is left at default and nothing is being shipped off the device.
✓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).
—Reading inside encrypted sites means pushing a certificate onto every company machine first. Phones brought from home will keep throwing warnings until somebody decides how to handle them.
✓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).
—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.
✓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).
—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.
✓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).
—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.
💡 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.

🔹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.
🔹Register the appliance and switch the security subscriptions on before cutover night at your office in Joygachi - a unit downloading its first threat update while thirty people wait is an avoidable delay.
🔹Add up the wattage of the access points before hanging them off a switch. A power budget that looks generous on paper runs out quickly once ceiling units and a couple of cameras are drawing from it.
🔎 Licence Tiers and What Each One Covers for businesses in Kolkata
Throughput is published several ways and only one of them matters to you. Ask for the figure measured with intrusion prevention and encrypted inspection both running, because that is the state the appliance will actually work in day to day. The larger number on the front of a brochure is measured with almost everything switched off.
Port layout decides what has to change in your rack. Copper gigabit ports handle desks and switch links, some models bring power-over-Ethernet ports for access points and cameras, and fibre cages are there when the core switch or the leased line handoff needs them. A USB socket takes a mobile modem for backup internet.

SonicWALL Quality Control and Field Return Handling
Nobody in your office receives an attachment the world has not seen before on trust alone; it is opened in a sealed test room in the cloud first and released only when the verdict comes back. Files are also watched while they run in live memory, which is how malware written to look harmless to an ordinary scanner gets caught (Real-Time Deep Memory Inspection).
Most infections now ride inside encrypted pages, so those pages get opened and read - and you decide which categories, banking and health among them, are left untouched. On the larger models that checking runs in hardware, so you can keep it switched on through the busiest hours instead of turning it off to buy speed.
✉️ SUPPORT DESK
Coordinate custom hardware configurations, AMC maintenance contracts, and site engineering visits directly with authorized integration desks.
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. 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. 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.
Q. 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.
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.
💡 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.
