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 Prince Anwar Shah Road before quoting and give you the honest number.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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 Prince Anwar Shah Road are running one that quietly stopped getting updates two years ago.

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.

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.

Buy SonicWALL Network Security Gateway for Branches in Prince Anwar Shah Road

The call almost always starts the same way: the billing software has gone sluggish, the CCTV feed stutters, and nobody can say which one is causing the other. Nine times out of ten the box at the door is an ISP router doing a job it was never built for. A SonicWALL UTM Firewall Appliance for Branch and Head Office reads the whole of a file as it arrives instead of sampling the first few pieces, so a disguised download does not get waved through (RFDPI). We size it against your real staff count and line speed, never against the number of ports on the front panel.

🤝 Local Engineers for SonicWALL UTM Firewall Appliance for Branch and Head Office around Prince Anwar Shah Road

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

Your branch has exactly one broadband line, and the morning it is cut by road work the branch stops billing. Add a second connection - even a 4G modem on the back of the unit - and the appliance watches both, moving billing and voice onto whichever one is healthy. Nobody has to phone head office to make that happen. Depots and small outlets across Kolkata run this way for roughly the price of a data pack (Secure SD-WAN).

Your ERP vendor wants remote access, your CCTV company wants remote access, and right now both hold the same password as your accountant. Each can instead be given an encrypted login that reaches exactly one machine on one port, with a second check at sign-in and a record of every session. Access can be switched on for the afternoon and off again by evening. That is a far smaller opening than the remote-desktop port most small offices in Kolkata leave facing the internet.

✅ 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 Prince Anwar Shah Road 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 Prince Anwar Shah Road 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

Licences are where firewall projects quietly fall over. We keep the expiry dates for the security bundle at every site, warn you well ahead of renewal, and spell out which checks stop working the day a subscription ends. Nobody gains from a customer finding out that on a Monday morning.

Everything below is chargeable and priced before we begin:

▪Licence Renewal Tracking and Bundle Reviews

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

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

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

*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: 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.

📁 Complete List of What We Supply across Kolkata

Throughput figures are shown with inspection on, which is the honest number:

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.

🔹 SIZE AND NOISE

Book-sized, fanless on the smaller models, quiet enough to live on a reception shelf without anyone noticing it is there.

🔹 BEST FOR

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

🔹 COMMON MISTAKE

Sizing by staff count alone. Count the cameras, IP phones and card machines too - every one of them holds connections open all day.

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.

🔹 SEVERAL ISP LINES

More than one connection terminates on the same unit and it decides what travels where (BGP, OSPF and dynamic SD-WAN routing).

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.

🔹 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.

🔹 BOTH UNITS WORKING

A pair can run live together rather than leaving one idle, which at this price is a better use of the money (Active-Active clustering).

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.

🔹 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.

🔹 WHO IT SUITS

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

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.

🔹 CHECK BEFORE ORDERING

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

🔹 PLANNING

Signal is eaten by brick walls, lift shafts and steel racking, so units get placed by the building's layout rather than by floor area.

🔹 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.

🔹 ONE LOGIN

The switch shows up in the same management console as the firewall, so ports and security rules are dealt with together.

🔹 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.

🔹 SUITS

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

Cloud Edge: Office Access for Staff Working from Home

Lets a person reach the one office server they need from home, a hotel or a client's site, without their laptop landing inside everything you own. Bought per person, not per building.

🔹 WHAT IT'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.

🔹 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 COSTS

Priced by the person by the month, so a team of six is paid for as six and not as the entire company.

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.

🔹 ONE CHANGE, EVERY SITE

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

🔹 SETTINGS BACKUP

Configurations are held in the cloud, so a replacement unit at a distant branch is rebuilt from the last known-good copy.

🔹 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.

🔹 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.

🔹 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.

⚙️ SYSTEM EVALUATION & CHECKLIST

Turnkey UTM Firewall Appliance for Branch and Head Office Metrics Checklist near Prince Anwar Shah Road

🛠️ Workflow Setup

A cutover slot is agreed with you, normally after closing or on a Sunday morning. Expect the internet to be down for about half an hour, and expect us to say so plainly rather than promise otherwise.

⚠️ Pitfalls to Avoid

Do not let the installer keep the only copy of the admin password. It happens constantly, and it turns a ten-minute change into a factory reset two years down the line.

🔌 Guidelines & Sizing

Find out what your generator does at changeover. If power drops for even a few seconds when it takes over, the firewall needs a UPS in front of it or it will reboot every single time the mains flickers.

📈 Upgrade Triggers

The VPN somebody set up years ago only lets two people in at a time, so the third person waits until one of them finishes.

🛠️ Patch Leads, Port Maps and the Photograph Nobody Takes

Small appliances get treated casually - put on a shelf, under a plant, behind a UPS - and are then blamed for being unreliable.

🛠️ Network Setup & Cabling - A Walkthrough across Kolkata

🔹Register the appliance and switch the security subscriptions on before cutover night at your office in Prince Anwar Shah Road - a unit downloading its first threat update while thirty people wait is an avoidable delay.
🔹Add up the wattage of the access points before hanging them off a switch. A power budget that looks generous on paper runs out quickly once ceiling units and a couple of cameras are drawing from it.
🔹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.

PRACTICAL GAINS IN ONE LIST

PREPARATION YOU WILL NEED - THE SHORT LIST

✓Running thirty sites the way you ran three stops working around site number six; head office sees every outlet in one list instead of ringing each manager (Network Security Manager).

—Single sign-on only names people whose accounts live in your directory. Contractors and shared machines will still appear as bare IP addresses in the report.

✓An ageing core switch and a new 10G uplink can end on the same appliance, so the network does not have to be replaced in one go (RJ45, 2.5GbE and SFP+ on larger models).

—Turning on full inspection cuts the headline throughput figure. Size the model against the traffic you actually intend to scan, or the first busy morning will show it up.

✓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).

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

✓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).

—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.

✓The audit question - who reached what, and when - is answered from the reports instead of from memory.

—Reading inside encrypted sites means pushing a certificate onto every company machine first. Phones brought from home will keep throwing warnings until somebody decides how to handle them.

💡 Engineering Fact: An attachment nobody in the world has seen before is held back for a couple of minutes and opened inside a cloud test room first. If it starts encrypting files there, your accounts team never receives it (Capture ATP).

📖 Where the Datasheet and Reality Differ around Prince Anwar Shah Road

In a crowded market street or a mall around Prince Anwar Shah Road, the 2.4GHz band is already full of everybody else's Wi-Fi and adding power does not help. Push what you can onto 5GHz, keep the older band for barcode scanners that genuinely need it, and place access points for coverage rather than for the convenience of the cable route.

Comparing one next-generation firewall versus another is less about the datasheet than about what you live with afterwards: how many sites a single console genuinely covers, whether the licence bundle is one line on the renewal or five, and what year three costs. Ask both vendors those three questions and the difference usually shows up in the answers rather than the throughput chart.

The router that came with your connection belongs, in every practical sense, to the internet company: they set the password, they update it when they feel like it, and it knows nothing about who in your office did what.

💡 Engineering Fact: Zoom, YouTube and your banking site all look identical from outside - encrypted traffic on the same port. The firewall recognises them by how each one talks, which is how a video call gets priority while streaming gets capped.

🧾 Licence Tiers and What Each One Covers in and around Prince Anwar Shah Road

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.

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.

Board Layout, Shielding and Heat Paths Inside the Case

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.

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.

Frequently Asked Questions

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. 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.

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. 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. 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.

💡 Engineering Fact: Your manager gets manager-level internet access from any desk in the building because the firewall reads who signed in to Windows and applies rules to the person rather than to the machine (Single Sign-On).
