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 South City Mall are running one that quietly stopped getting updates two years ago.

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.

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.

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 South City Mall before quoting and give you the honest number.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

SonicWALL UTM Firewall Appliance for Branch and Head Office Sizing, Licensing & Onsite Support near South City Mall

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 South City Mall.

📍 Sizing, Licensing and Ordering SonicWALL UTM Firewall Appliance for Branch and Head Office across Kolkata

Underside label of the appliance showing its serial number and model name

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.

The security box in your rack still shows a green light, which is the most misleading thing about it. Once the subscription lapsed it stopped receiving new threat information, and it was never built to look inside the encrypted traffic that now carries almost everything. We read the old rules, rebuild only the ones still in use on a current SonicWALLUTM Firewall Appliance for Branch and Head Office, and switch over in the evening at your office in Kolkata. The old unit stays racked and powered off for a week in case anybody misses something.

💡 The Case for Doing It Properly Once across Kolkata

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.

Hotels, restaurants and showrooms in South City Mall that hand out Wi-Fi to customers are expected to know who used it, and a password written on a card tells you nothing. The same appliance can put a login page in front of guest Wi-Fi, keep a record of who connected and when, and expire that access by itself at closing time. Visitors get their internet, your working network stays out of reach, and there is a list if anybody official ever asks for one. It is the sort of thing nobody thinks about until the day they must.

Franchise Outlets That Open Faster Than Anyone Can Travel

A hotel group running three properties around Kolkata had guests, the front-desk booking system and the restaurant billing machine sharing one network and one password. We split guest Wi-Fi away from the working network entirely, gave each property access points managed from the firewall, and put reception on a lane of its own. Guests still connect in one tap from the lobby to the top floor. The group answered its booking partner's security questionnaire with a network diagram instead of an apology.

🛡️ HOW A ROLLOUT ACTUALLY RUNS

The Paperwork You Get at Handover

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:

▪Encrypted Traffic Inspection and Certificate Rollout

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

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

▪Moving Off Your Old Firewall Without Downtime

*Note: every survey, configuration change and site visit listed above is a paid service, quoted before work begins, and separate from any assistance you receive directly from the manufacturer.*

💡 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.

📦 Available Options and Typical Fit near South City Mall

Included accessories are marked, so nothing surprises you at delivery:

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.

🔹 TWO INTERNET LINES

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

🔹 BEST FOR

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

NSa Rack Firewalls for a Head Office or Campus

One-rack-unit NSa gateways for the main office of a company, a nursing home group or a college - anywhere a few hundred people share the same line from morning to night. Built to bolt into the cabinet you already own.

🔹 TWO POWER FEEDS

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

🔹 WORKING PACE

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

🔹 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.

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.

🔹 WEIGHT

A two-person lift, on rails rated for the load. An appliance this heavy resting on cabinet ledges will sag and take its ports with it.

🔹 LOGS ON BOARD

Internal SSDs hold traffic history on the appliance itself, so a question about last month does not need a separate log server.

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.

🔹 CABLE POWER

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

🔹 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.

🔹 CHECK BEFORE ORDERING

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

Managed Switches on the Same Console as the Firewall

Switches that report to the same screen as the firewall, so ports, cameras and phones are handled from one login. For offices past the stage of stacking small unmanaged boxes under a desk.

🔹 SUITS

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

🔹 ONE LOGIN

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

🔹 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.

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.

🔹 WHEN NOT TO BOTHER

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

🔹 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.

🔹 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.

🔹 FIRMWARE

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

🔹 SETTINGS BACKUP

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

🔹 WHAT IT WILL NOT DO

It does not replace somebody reading the reports. The console tells you; it does not decide for you.

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.

🔹 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.

🔹 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.

🔹 HOW WE TRACK IT

Microtech Solutions holds the expiry dates and raises them early, so nobody is chasing a renewal on the last working afternoon.

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.

📊 Capacity, Limits and Sizing Guide for offices in South City Mall

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.

SonicWALL Quality Control and Field Return Handling

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.

🛠️ Choosing a Spot for the Gateway on a Small Site

Go through these before the delivery date, not on the day an engineer is standing in your server room with a screwdriver.

🏢 Network Setup & Cabling - Explained Simply anywhere in Kolkata

🔹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.

WHAT YOU GET FOR THE MONEY - THE HIGHLIGHTS

REAL LIMITS - THE HONEST VERSION

✓An older box simply passed https pages along unread, and that is precisely where the trouble hides today; those sessions are opened and checked, with banking and health sites left alone by policy (TLS deep inspection).

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

✓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.

—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.

✓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.

—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.

✓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).

—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.

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

—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.

💡 Engineering Fact: Generator changeover is harder on network equipment than the power cut itself. The spike as the load transfers is a common reason a power supply gives up, and an online UPS in between is the cheapest insurance in the room.

📝 Questions Customers Ask Us Most across Kolkata

If you are buying a pair for high availability, make sure both units are registered together and the licensing is associated correctly, or the standby will come up without its protection services running. Test the failover once in a planned window and note how long a live call takes to come back. A pair nobody has ever tested is an assumption, not a plan.

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.

A security box bought around 2015 will still boot happily. Its threat feed stopped the day the licence did, and its processor was never designed for traffic that is now almost entirely encrypted.

💡 Engineering Fact: Guest WiFi cannot reach your accounting server, and the reason is not the password. The two sit in separate zones with no rule joining them, so nothing crosses unless someone deliberately writes that rule.

Frequently Asked Questions

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. 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.

Q. 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.

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. 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.

💡 Engineering Fact: The clever part of that test is not the testing, it is the holding. The mail waits in the queue until a verdict comes back, so nobody has to be trusted to remember not to click.
