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.

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.

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.

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.

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.

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.

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.

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 Dhakuria before quoting and give you the honest number.

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.

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.

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.

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.

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.

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.

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.

SonicWALL Business Network Security & Failover Setup near Dhakuria

How much of your own network can you actually see from where you sit? For an owner running four outlets the honest answer is usually none of it: every shop has its own router, its own password and its own problem. Put a SonicWALL unit at each site and they all report into one dashboard, so the outlet and the warehouse appear on the same screen (Network Security Manager). Opening a fifth shop then becomes a form to fill in rather than a trip out of town.

🤝 SonicWALL Deployment, Migration and Handover around Dhakuria

Boxed appliance opened on a table with its power adapter and mounting kit near Dhakuria

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).

✅ Benefits Your Accounts Team Will Notice throughout Kolkata

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 Dhakuria with no IT department of their own, that arrangement is usually why the equipment stays healthy.

The awkward moment in most audits is the question about which staff can open the accounting system, and from which machines. Because rules are written against your office logins, the answer comes out of the console as a list of names rather than a promise from memory. Reports can be scheduled so the evidence already exists before anyone asks for it. Firms dealing with banks, exporters and listed customers get asked this far more often than they expect.

Guest Wi-Fi in Hotels Without Touching the Booking System

A distributor of agricultural inputs, with a head office near Dhakuria and six godowns, ran each depot on whatever connection its town offered, and stock entries were often typed twice because the link dropped mid-save. Each depot now runs a small unit linked back to head office through an encrypted tunnel, with mobile data waiting behind the wired line. Stock movements are entered once and reach the central system while the storekeeper is still at the desk. During the sowing rush that alone removed a week of reconciliation work.

🛡️ WHAT GETS DOCUMENTED AND HANDED OVER

Reaching Us After the Job Is Done

Dropping a SonicWALL appliance into a network that is already carrying live work begins with an inventory, not a toolkit. We write down what actually runs at your site in Dhakuria - the Tally server, the biometric reader, the CCTV recorder, the second broadband line nobody documented - before a single rule is typed. Only then is a switchover slot agreed, usually after closing time, with a tested way back if something misbehaves.

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

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

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

▪Supply, Configuration and Go-Live of the Appliance

▪Licence Renewal Tracking and Bundle Reviews

*Important: night-time switchovers and same-day emergency visits are priced separately and confirmed with you first. None of it counts as manufacturer support.*

💡 Engineering Fact: A cheap router glances at the first few pieces of a download and waves the rest through. This one reads the file all the way from first byte to last as it arrives, which is why a virus split across several packets still gets caught (RFDPI).

📡 WI-FI AND SWITCHES TOO

📁 Product and Licence Line-Up for offices in Dhakuria

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.

🔹 TWO INTERNET LINES

Fibre and a broadband backup stay plugged in together and the box quietly uses whichever one is behaving (Secure SD-WAN).

🔹 WHEN YOU GROW

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

🔹 WIFI BUILT IN

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

🔹 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.

🔹 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).

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).

🔹 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.

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.

🔹 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.

🔹 WHO IT SUITS

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

🔹 REPORTING

Head office can see each branch's uptime and how its line is performing, which ends the argument about whose internet is at fault.

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.

🔹 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.

🔹 CHECK BEFORE ORDERING

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

🔹 CABLE POWER

One cable does both jobs, signal and electricity, which is why mounting height stops being an electrical problem (PoE).

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.

🔹 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.

🔹 BETWEEN BUILDINGS

Copper stops being useful at about ninety metres. Past that the uplink goes on fibre, and these units take fibre directly.

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.

🔹 NO BOX AT HOME

The service runs from the cloud, so somebody who joins today is not waiting for hardware to be couriered to their flat.

🔹 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.

🔹 ONE CHANGE, EVERY SITE

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

🔹 WHAT IT'S FOR

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

Security Bundles and Licence Renewals

Firewalls are sold with a subscription behind them: threat updates, filtering, sandbox checks and vendor support. This is how those are bought, bundled and renewed without leaving a gap.

🔹 MULTI-YEAR TERMS

Paying for three years at once holds the price still and removes two more rounds of quotations, approvals and reminder calls.

🔹 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.

🔹 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.

🧾 Feature List and Technical Detail in and around Dhakuria

Redundancy comes in layers and you can buy them one at a time. A second internet connection is the cheapest, a mobile modem behind it is cheaper still, and a paired second appliance covers the unit itself failing. Rack models take two power supplies, which matters in buildings where the generator changeover is not gentle.

The range is easier to understand than the model numbers suggest. TZ units are desktop boxes for a shop, a clinic or a branch of twenty to fifty people; NSa models are rack appliances for a head office or a busy campus; NSsp sits above that for data centre work. Most businesses we quote in Kolkata end up with a TZ at each branch and one NSa at head office, and that combination behaves as a single network.

🏆 CORE PARAMETER🔌 Second power supplyOptional on smaller rack models, standard and hot-swappable on the large ones

🔹 Brand-new threatsLive memory inspection plus the Capture ATP cloud sandbox (RTDMI)

🔹 Shapes it comes inFanless desktop TZ, 1U rack NSa, 2U rack NSa and NSsp

🔹 If the box diesActive-Standby or Active-Active pair with stateful failover

🔹 Network socketsCopper 1GbE on every model, 2.5GbE multi-gig on the TZ 570 and 670, and 10GbE SFP+ fibre on the larger rack units - the mix depends on the model ordered

🔹 Linking your branchesIPsec site-to-site tunnels, SSL VPN for staff, Secure SD-WAN across lines

🔹 How it scansThe whole stream is reassembled and read, with no cap on file size (RFDPI)

How to Tell a Grey-Market Box From a Genuine One in Dhakuria

SonicWALL builds this range for organisations whose people are spread over many small sites rather than gathered in one building. The same operating system runs on a desktop unit in a single shop and on a rack appliance at head office, so a policy written once can be applied everywhere without translation.

Nothing waits in a queue while a scanner collects a whole file first, so a large drawing or a software installer arrives at the pace your line allows and is still checked on the way in. You never have to set a maximum file size and hope nothing bigger turns up, because traffic is read as it flows (Reassembly-Free Deep Packet Inspection).

🛠️ Workflow Setup

On the day itself the box goes in, power comes off two separate points where the room allows, and your line is shifted over from the old router. That old one stays wired for the twenty minutes it takes to be sure.

⚠️ Pitfalls to Avoid

Turning on every scanning feature at once on day one guarantees complaints. Bring them up in stages and give the office time to get used to each one.

🔌 Guidelines & Sizing

Insist on solid copper Cat6 with the maker's marking printed on the jacket. The cheap copper-clad aluminium sold under the same name heats up, loses signal over distance, and produces faults everyone blames on the provider.

BENEFITS YOU WILL NOTICE IN ONE LIST

COMMON COMPLAINTS - THE SHORT 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.

—Rack units are loud. Put one in the corner of an open office and you will hear about it within a fortnight.

✓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).

—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.

✓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.

✓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.

—Somebody has to own the rule list. Without that, the temporary allow-rules added before last Diwali are still open and nobody remembers who asked for them.

✓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).

—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: The number on a firewall's spec sheet that runs out first is usually not speed but the count of simultaneous connections. Fifty cameras and a hundred IP phones hold thousands of them open all day while doing very little.

🔧 Labelling & Documentation - A Timeline around Dhakuria

🔹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.
🔹Set a reliable time source on the appliance before go-live. Logs carrying the wrong timestamp are useless during an audit and worse during an incident.
🔹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.

📖 Common Failures and How We Fix Them around Dhakuria

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: 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.

Frequently Asked Questions

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. 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. What happens to an attachment that nobody has ever seen before?

It is held at the gateway and opened first in a cloud test-room, where several engines run it and watch what it tries to do (Capture ATP). The part that catches current ransomware is the memory check: malware that only unpacks itself while running is caught in the act inside processor memory, which a signature scanner never gets to see (RTDMI). If the file behaves, it is released to the recipient in about a minute; if not, it is blocked and logged with the sender's details. You choose whether to hold every file until the verdict or deliver first and alert afterwards - the first is safer, the second keeps a sales team happier.

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

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: 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.
