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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 Durgapur before quoting and give you the honest number.

Buy SonicWALL Network Security Gateway for Branches in Durgapur

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 Durgapur.

🏢 SonicWALL UTM Firewall Appliance for Branch and Head Office Supply, Setup and Support in and around Durgapur

Green and amber indicator lamps glowing along the front edge of the running appliance

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.

🎯 Good Reasons to Move Off Your Current Setup in and around Durgapur

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 Durgapur 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 Durgapur 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

Most of the money wasted on firewalls is wasted at the sizing stage. We ask how many people are online together, how much of that traffic you intend to inspect, and whether branches are joining in - then quote the model that survives a bad Monday. Equally, if the smaller TZ is genuinely enough, we say so, because selling you an NSa you do not need is a short win and a long problem.

These are the tasks we are usually called in for:

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

▪Moving Off Your Old Firewall Without Downtime

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

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

*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: Blocking a whole category like gambling does not mean somebody sat and typed out a list of websites. The firewall asks a cloud rating service what category the address belongs to, and the answer comes back faster than the page loads.

📦 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 Durgapur.

📋 Available Options and Typical Fit near Durgapur

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.

🔹 WIFI BUILT IN

Several models carry their own wireless, which saves buying a separate access point in a one-room office.

🔹 BEST FOR

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

🔹 SOCKETS

Six to ten network points, some of them 2.5-gigabit, with a fibre slot on the larger models for a leased line.

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.

🔹 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.

🔹 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.

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.

🔹 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.

🔹 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).

🔹 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.

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.

🔹 THE PROBLEM IT SOLVES

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

🔹 WHERE IT SUITS

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

🔹 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.

🔹 SUITS

Warehouses, hospitals and any premises where the camera count has quietly doubled since the cabling was first laid.

🔹 WHAT IT'S FOR

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

🔹 FINDING THE FAULT

When one machine floods the network, the guilty port is named on screen and closed from there, instead of by pulling cables one at a time.

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.

🔹 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.

🔹 WHEN NOT TO BOTHER

If everyone works in one building and nobody travels, put the money into the firewall instead.

🔹 LOST LAPTOP

One click ends that person's access. Nobody has to change a shared VPN password and then explain it to forty people.

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.

🔹 FIRMWARE

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

🔹 ALERTS

A branch losing its line, or a licence coming up for expiry, reaches you by mail before the branch manager rings.

🔹 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.

🔹 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.

🔹 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.

🧰 Who You Call at Nine in the Evening for offices in Durgapur

Type of Business	What the Work Covers	Typical Lead Time
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
Business Centres and Shared Office Floors	A private lane and a fair slice of the line for each tenant, with no way to browse into the company at the next desk	Survey first, cutover on an agreed weekend
Cold Storage and Cold-Chain Depots	Chamber monitoring and dispatch stay connected when the main line drops, because the backup connection takes over on its own	Planned around loading hours, generally mid-week

⏱️ How It Performs on a Normal Working Day in and around Durgapur

CLEAR ADVANTAGES AT A GLANCE

COSTS BEYOND THE QUOTE SET OUT PLAINLY

✓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).

—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.

✓At a site you cannot simply switch off, a failed power supply on the rack models is replaced while the box keeps running (hot-swap PSU).

—Fibre ports arrive empty. Transceivers or DAC cables are ordered separately, and a mismatched part will simply refuse to come up.

✓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).

—Firmware upgrades drop live sessions for a moment. On a single appliance that means an after-hours window agreed with whoever works late.

✓Half the trouble in a small office starts with one shared login that everybody knows. Once each person signs in as themselves, the report finally names who did what (Single Sign-On with Active Directory).

—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.

✓Stock figures that reach head office a day late are usually a tunnel problem rather than a software one; every shop links back over one encrypted connection (site-to-site IPsec).

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

💡 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.

🛠️ 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.

💬 Engineer Notes From Real Installations in and around Durgapur

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: Two internet lines are never identical, and the firewall knows it. It measures delay and lost packets on each one continuously, so your calls can sit on the steady line while big downloads go over the other.

🔎 Capacity, Limits and Sizing Guide for businesses in 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.

How These Units Are Built and Tested

If one internet line dies at eleven in the morning, your billing counter should not. Two or three connections, a mobile modem included, are measured all the time and traffic is moved onto whichever is behaving; when the dead line returns, your branch tunnels come back on their own without anyone travelling to site (Secure SD-WAN).

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

🏢 Installation & Setup - The Plan for small and mid-sized teams

🔹Give the appliance its own management address on a separate VLAN and turn administration off from the internet side completely; reach it over the VPN when you are away from the office.
🔹Point the failover probes at something outside your provider's network, such as a public DNS address. Probing the provider's own gateway means a dead upstream link still looks perfectly healthy.
🔹Add the serial number to the cloud console before the box is couriered to a branch, whether that branch is across Kolkata or three states away, so staff there only have to connect power and the internet cable.

Frequently Asked Questions

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

Q. 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.

Q. 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.

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.

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.

💡 Engineering Fact: If you ever have to prove what left your network on a particular Tuesday afternoon, the answer comes off the firewall's own storage. Logs are written to an internal SSD, which is why on-box storage matters to anyone facing an audit.
