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.

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.

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.

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 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.

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.

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.

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 Howrah Maidan 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.

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.

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 Howrah Maidan 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.

Original SonicWALL Firewall Appliance Setup & Support in Howrah Maidan

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 Supply and Aftercare for Business Buyers near Howrah Maidan

Larger NSa model fitted into a rack between a network switch and a patch panel

The lease is signed, the outlet opens in three weeks, and your one IT person is already booked at head office that fortnight. A SonicWALLUTM Firewall Appliance for Branch and Head Office can be registered here, couriered to the site and brought online by whoever is standing there with a plug and an internet cable. The rules, the Wi-Fi settings and the tunnel back to head office arrive by themselves once it powers up. Chains adding shops around Howrah Maidan use this so opening dates stop depending on somebody's travel calendar (Zero-Touch Deployment).

Somebody switched the scanning off years ago because the network slowed to a crawl, and nobody has switched it back on since. This appliance examines traffic as it streams past instead of holding whole files in memory first, which is why the checks can stay on through your busiest hour. Large downloads, backups and cloud accounting sessions all keep moving. It is a different way of reading traffic, and it is the reason a modest unit inspects far more than you would expect (Reassembly-Free Deep Packet Inspection).

🌟 Reasons This Works for Small Offices near Howrah Maidan

The commonest firewall mistake is not buying the wrong brand, it is buying one model too small and then switching features off to keep it comfortable. We size against your real headcount, your internet speed and what you expect to add over the next two or three years, then leave headroom above that. A TZ suits a shop or a branch anywhere in Kolkata; an NSa suits a head office carrying branch tunnels and remote staff. Getting that choice right once costs far less than replacing the box in year two.

A firewall that arrives as a sealed carton and a PDF is not much help to a business with no IT team. Every unit is configured, updated and run in at our Kolkata bench before it ships, carrying your addressing, your rules and your Wi-Fi settings already. Ports are labelled, the configuration file is saved, and the handover includes a diagram rather than a login and good luck. If a unit fails inside warranty we handle the replacement and put the saved settings straight back on it.

Unmanned Sites and Payment Terminals in and around Howrah Maidan

A pharmacy chain with counters in several towns kept losing billing whenever the local cable connection dipped, and each shop had a different person guessing at the router. Every counter now runs the same small appliance with a mobile data connection standing behind the wired one. When a line drops, billing carries on over the backup while the alert reaches the head-office desk. Nobody at shop level has been asked to reboot anything since the changeover.

🛡️ STRAIGHT SIZING ADVICE, INCLUDING NO

Keeping Track of Licences and Renewal Dates

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:

▪Supply, Configuration and Go-Live of the Appliance

▪A Standby Box So One Failure Does Not Stop Work

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

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

*Fair notice: attendance outside your contracted window attracts a call-out fee, agreed before dispatch, and it has no bearing on manufacturer service.*

💡 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).

🔖 Available Options and Typical Fit for offices in Howrah Maidan

Scan the details, then ask us which one suits your line speed:

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.

🔹 POWER DRAW

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

🔹 WHEN YOU GROW

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

🔹 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.

🔹 TWO POWER FEEDS

Fit the second supply and run it from another circuit. The day an electrician isolates one board, the network stays up.

🔹 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.

🔹 WORKING PACE

Virus scanning, intrusion checks and encrypted-site inspection can all run together while the branch tunnels stay usable.

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).

🔹 NOISE

Nobody enjoys sitting next to one of these. Plan for a real server room, not a cabin behind the accounts desk.

🔹 AIRFLOW

Fan trays are changed without a shutdown, and the front-to-back path has to stay clear - no cartons leaning against the cabinet.

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.

🔹 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.

🔹 COST NOTE

A branch unit and its subscription usually work out below a leased line to the same location, which is the whole argument for SD-WAN.

SonicWave WiFi Access Points for Full Floor Coverage

SonicWave units screwed to the ceiling so the signal reaches the far end of the floor. For any building where the WiFi works near the router and nowhere else.

🔹 VISITORS

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

🔹 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.

🔹 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.

🔹 BETWEEN BUILDINGS

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

🔹 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.

🔹 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.

🔹 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.

🔹 LOST LAPTOP

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

🔹 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.

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.

🔹 REPORTS

Monthly summaries of what was blocked and where the day's bandwidth went, in a shape a director will actually read.

🔹 WHO IT SUITS

Retail chains, franchise groups, NBFCs with branch offices, and hospital groups running four or five units across Kolkata.

🔹 AUDIT TRAIL

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

Security Bundles and Licence Renewals

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

🔹 WHAT 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 A RENEWAL IS THE WRONG ANSWER

If headcount has doubled since you bought, ask for a comparison against a larger unit before you sign anything.

🔹 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.

🛠️ Handing the Site Over: What the Customer Should Get

Most of what follows costs nothing and takes ten minutes; the alternative is a callback during your busiest week of the month.

🔧 Server Room Housekeeping - How It Works in Howrah Maidan

🔹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.

📌 Honest Pros and Cons From the Bench near Howrah Maidan

Check which mode the cloud file analysis is set to. In one setting the file is delivered to the user and you are told afterwards that it was bad; in the other it is held until the verdict arrives. For anything reaching accounts or buy mailboxes I set it to hold - a few seconds of delay is not a business problem, and the alternative certainly is.

A shop-grade wireless router with the word firewall printed on the carton gives you no user identity, no separation between the guest and the till, and a weekly reboot as its maintenance plan.

Buying web filtering from one vendor, VPN from another and antivirus from a third leaves three renewal dates in the diary, three consoles to learn, and nobody to call when they disagree with each other.

💡 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).

📌 Contract Terms Without the Small Print near Howrah Maidan

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
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
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

🖥️ What Happens When Everyone Logs In at Once near Howrah Maidan

Both columns are worth reading before you settle on a model.

EVERYDAY WINS IN BRIEF

WHAT NEEDS SETTING UP FIRST IN ONE PLACE

✓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).

—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.

✓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.

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

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

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

✓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).

—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.

✓Renewals arrive as one date rather than four, since filtering, sandboxing and the threat feed sit in a single bundle registered against the serial number.

—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.

💡 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.

🛠️ 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.

📈 Upgrade Triggers

Half the staff now work from home part of the week through a remote desktop port that was opened in a hurry and has never been closed since.

📌 Capacity, Limits and Sizing Guide near Howrah Maidan

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.

What Happens on the Production Line

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).

Frequently Asked Questions

Q. 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.

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. 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. 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.

Q. 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.

💡 Engineering Fact: Firewall firmware is not a phone update you can put off for two years. Fixes for holes that are already being exploited arrive in it, and a unit three versions behind is doing rather less than its owner believes.
