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.

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.

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 Selimpur before quoting and give you the honest number.

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.

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.

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.

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.

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.

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.

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.

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 Selimpur 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.

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 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.

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.

Authorized SonicWALL UTM Gateway Sales & Maintenance in Selimpur

Here is the part the datasheet leaves out: the appliance is the cheaper half. Security services come as bundles, they expire on a date nobody wrote down, and a firewall with a lapsed subscription is a router with a good logo on it. We put the hardware, the bundle and the support term on one quote with a single renewal date, and we say in ordinary words what each line pays for. Nobody should learn that their cover ended by watching a threat walk in.

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

Firewall fixed inside a wall-mounted cabinet with a UPS sitting below it

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

The owner is convinced the office spends half the afternoon on video, the staff insist the internet is simply slow, and neither side has any evidence. Category filtering closes the obvious time sinks during working hours only, while per-person reports show who actually used what. Most of the argument disappears in the first week, usually because the real culprit turns out to be a machine nobody was sitting at. Rules can be softer for management and stricter for the shop floor, with nobody maintaining a spreadsheet.

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

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

Nobody enjoys finding out, halfway through a bad week, that the security subscription lapsed in March. We put the hardware, the bundle and the renewal date on one page in writing, and say plainly which services an office like yours will actually use. If a service in the bundle would never earn its keep in your office, we say so rather than let it pad the invoice. Businesses around Selimpur usually find the licence conversation more useful than the hardware one.

Depots and Godowns on Whatever Connection the Town Offers

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

🛡️ SUPPORT ONCE THE INVOICE IS SETTLED

How We Plan a Firewall Rollout

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

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

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

▪Licence Renewal Tracking and Bundle Reviews

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

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

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

💡 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.

👥 LOGINS, NOT IP ADDRESSES

Shared counters, shift staff and an audit trail full of machine names? We tie firewall rules to your office login system so reports read as people, across every site you run from Selimpur.

📚 Ranges Sorted by Office Size for Selimpur

Compare the branch boxes against the head office models here:

TZ Desktop Firewalls for a Shop or Single Branch

The small box that sits on a shelf behind the counter and guards one or two internet lines. Right for a showroom, a clinic, a site office or any team of roughly five to fifty people.

🔹 SPEED

Scanning happens on the same multi-core chip that moves the traffic, so switching virus and web filtering on does not turn browsing into a crawl.

🔹 POWER DRAW

Modest enough that a small UPS carries the firewall, the modem and the switch straight through a cut.

🔹 BEST FOR

A single location of about five to fifty staff - one showroom, one clinic, one small factory office.

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.

🔹 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).

🔹 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.

🔹 FIBRE UPLINKS

Ten-gigabit fibre ports land straight on the core switch, which keeps a media converter off the list of things that can fail (SFP+).

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.

🔹 PORT SPEEDS

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

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.

🔹 WHO IT SUITS

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

🔹 IF THE LINE DROPS

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

🔹 IF A UNIT DIES

Courier a replacement. It collects the same configuration by itself, so the branch is usually back on the same day.

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.

🔹 WHERE IT SUITS

Factory floors, hostels, showrooms with roaming billing tablets, and offices that have run out of desk network points.

🔹 VISITORS

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

🔹 CHECK BEFORE ORDERING

Where the network cabling already runs. Pulling fresh cable through a finished ceiling costs more than the access point does.

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.

🔹 POWER BUDGET

Ports and watts are two different limits. A switch can have sockets to spare and still run out of power for the cameras plugged into them.

🔹 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.

🔹 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.

🔹 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.

🔹 AUDIT TRAIL

Every configuration change is recorded against a name and a time, which settles most arguments before they properly start.

🔹 FIRMWARE

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

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 THE BUNDLE COVERS

Gateway antivirus, intrusion prevention, web and application control, the cloud sandbox and firmware support, usually under one name and one date.

🔹 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.

🔹 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.

✅ Warranty, Spares and Replacement Cover for single-office teams

Type of Business	What the Work Covers	Typical Lead Time
Small Factories and Fabrication Units	Machines, cameras and office computers on separate lanes, plus a link to the sales office that holds through the shift	Around three working days in most service areas
Franchise Outlets and Brand Stores	One rule set built once and copied to every new outlet, so a store opening in another city works the day its box is plugged in	Usually within a week of the order, subject to stock
Car and Two-Wheeler Dealerships	Showroom counters, service bay tablets and the workshop system kept apart, all visible from the group's head office	Roughly two working days per branch

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

CLEAR ADVANTAGES - IN PLAIN WORDS

COSTS BEYOND THE QUOTE SPELLED OUT UPFRONT

✓A salesman on hotel WiFi can reach the office system with nothing installed on his laptop and no port left open to the whole internet (SSL VPN with a second login check).

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

✓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).

—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.

✓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.

✓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).

—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.

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

—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.

💡 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.

🧮 Key Figures Every Buyer Should Check for larger offices

Wireless is part of the same product rather than a separate buy. Some models carry radios inside the unit itself; on the rest you add access points that the firewall adopts and manages, with no controller box or licence server sitting in the rack. One set of Wi-Fi settings then covers every floor and every branch.

Two numbers govern sizing beyond raw speed: how many connections the unit holds at once, and how many remote users can be signed in together. A shop in Selimpur with ten machines and a camera recorder uses more connections than people expect, and a work-from-home week doubles the second figure. Give us your peak rather than your average and the model we quote will have room in it.

How These Units Are Built and Tested

New sites can be brought online without an engineer travelling to them. An appliance registered to the account contacts the cloud service on first power-up, downloads its configuration and joins the organisation's network on its own.

Wireless access points and managed switches are administered from the same interface as the firewall. Network policy, guest access and port power are handled in one place, which removes both a controller appliance and a separate management server from the site.

🛠️ Shops, Counters and the Cabinet Behind the Billing Desk

If the appliance is going into a plant, a godown or a kitchen, dust and heat matter more than anything printed in the datasheet.

✅ Server Room Housekeeping - The Plan for small and mid-sized teams

🔹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.
🔹Install the single sign-on agent on an ordinary member server using a read-only service account, then confirm that a shared counter machine shows the correct user name in the log before you write any person-based rules.
🔹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.

🗒️ Engineer Notes From Real Installations for demanding workloads

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

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

Cloud-only filtering works on a laptop that has the agent installed and an internet connection. It does nothing between two machines standing in the same shop, and nothing at all for equipment that can never carry an agent.

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

🛠️ Workflow Setup

Finally the paperwork: logins, rule list, port labels and licence dates, handed over properly. A fortnight later somebody goes back through the logs and turns down whatever has been over-alerting.

⚠️ Pitfalls to Avoid

Do not buy the smallest model assuming features can be added later. Adding a licence is easy; adding capacity means buying the box a second time.

🔌 Guidelines & Sizing

Keep one spare patch lead of every type you use inside the cabinet, copper, fibre and the direct-attach sort. A faulty lead at nine at night should be a two-minute swap, not a drive across town.

📈 Upgrade Triggers

Nobody can tell you how many devices are on the network. The honest guess is somewhere between forty and a hundred and twenty.

Frequently Asked Questions

Q. 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.

Q. 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.

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. 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.

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.

💡 Engineering Fact: Padlock icons stopped meaning safe a long while ago - the padlock only hides what is travelling. The firewall opens that envelope, reads what is inside and seals it again, doing the heavy maths in dedicated hardware so nobody notices the pause.
