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

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

SonicWALL UTM Firewall Appliance for Branch and Head Office Hardware Sizing & Licence Desk in Garifa

Buying the biggest model the budget allows is the mistake I meet most often, and it is a costly one. A TZ carries a busy branch comfortably, an NSa suits a head office with servers and staff dialling in from home, and NSsp is data-centre kit that a forty-seat firm has no business paying for. What really decides it is how many people are online together, whether you want encrypted traffic inspected, and how many branch tunnels you need. Give me those three answers and the model picks itself.

🧭 Local Engineers for SonicWALL UTM Firewall Appliance for Branch and Head Office at multi-branch offices

Product photo of the UTM Firewall Appliance for Branch and Head Office on a plain white background, seen from an angle

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.

🔑 Why Businesses Pick SonicWALL UTM Firewall Appliance for Branch and Head Office when budgets are tight

Connecting four or five branches across Kolkata to head office used to mean a leased line to each one, which most businesses could never justify. Ordinary broadband at every site, joined by encrypted tunnels through these appliances, gives you a single network for a small fraction of that. Staff at a depot open the same software they would open at head office, at whatever speed the local line allows. Adding the sixth site later is an afternoon's work, not a fresh project.

Nobody enjoys finding out, halfway through a bad week, that the security subscription lapsed in March. We put the hardware, the bundle and the renewal date on one page in writing, and say plainly which services an office like yours will actually use. If a service in the bundle would never earn its keep in your office, we say so rather than let it pad the invoice. Businesses around Garifa usually find the licence conversation more useful than the hardware one.

Depots and Godowns on Whatever Connection the Town Offers

A sweets and namkeen chain with fourteen outlets across Kolkata was opening two more before the festival season and had nobody free to travel. We registered both appliances here, couriered them out, and the shop staff plugged them into power and the broadband socket. Each unit pulled down its own rules, its guest Wi-Fi settings and the tunnel back to head office without an engineer on site. The second shop was billing on its opening morning, which had not happened with the previous three openings.

🛡️ SUPPORT ONCE THE INVOICE IS SETTLED

How We Plan a Firewall Rollout

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 Garifa - 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:

▪Encrypted Traffic Inspection and Certificate Rollout

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

▪Yearly Support Contracts with Agreed Response Times

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

*Terms: engineer hours, travel and any parts fitted are invoiced under a private service agreement that stands apart from the product warranty.*

💡 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.

👥 LOGINS, NOT IP ADDRESSES

Shared counters, shift staff and an audit trail full of machine names? We tie firewall rules to your office login system so reports read as people, across every site you run from Garifa.

📚 Product and Licence Line-Up in and around Garifa

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.

🔹 SOCKETS

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

🔹 SIZE AND NOISE

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

🔹 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.

🔹 TWO POWER FEEDS

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

🔹 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.

🔹 FIBRE UPLINKS

Ten-gigabit fibre ports land straight on the core switch, which keeps a media converter off the list of things that can fail (SFP+).

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.

🔹 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).

🔹 NOISE

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

🔹 PORT SPEEDS

Twenty-five and forty-gigabit fibre sockets are on offer, which keeps the security check from becoming a queue between server rows.

Branch Boxes That Set Themselves Up (Zero-Touch SD-WAN)

For the extra showroom, the godown office, the site cabin. You courier the unit, somebody local plugs in power and internet, and it pulls down its own settings and joins the head office network.

🔹 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.

🔹 SETUP

Nobody technical travels. The unit is registered before it leaves us and fetches its own configuration the first time it is switched on (Zero-Touch Deployment).

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.

🔹 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.

🔹 WHERE IT SUITS

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

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.

🔹 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.

🔹 WHAT IT'S FOR

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

🔹 FINDING THE FAULT

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

Cloud Edge: Office Access for Staff Working from Home

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

🔹 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.

🔹 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.

🔹 WHAT IT'S FOR

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

🔹 AUDIT TRAIL

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

🔹 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.

🔹 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.

🔹 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.

✅ Service Levels in Plain Language for single-office teams

Type of Business	What the Work Covers	Typical Lead Time
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
Engineering and Degree Colleges	Hostel WiFi kept well away from accounts and examination systems, with heavy streaming held back during class hours	Scheduled inside a semester break
Nursing Homes and Multi-Speciality Hospitals	Patient records and billing separated from the reception counter, and consultants reading reports from home without opening the whole network	Priority slot for contract sites, otherwise next available

PRACTICAL GAINS - IN PLAIN WORDS

PREPARATION YOU WILL NEED SPELLED OUT UPFRONT

✓Nobody has to remember to press update: the known-bad list refreshes on its own schedule, so cover does not quietly age between service visits.

—Real redundancy needs two identical appliances, not one box and a spare in the cupboard. The second unit is a second buy, and its licence position needs confirming before you order.

✓Ransomware written last week matches nothing on a signature list, so suspicious files are watched while they run instead of being judged on what they look like (RTDMI).

—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.

✓Large engineering drawings and installer files are not skipped for being too big, because there is no size cut-off on the scan (RFDPI).

—Zero-touch rollout still needs a live internet connection at the branch and the right serial registered in the portal. Get either wrong and the box sits there blinking.

✓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).

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

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

—Hardware faults are settled under the manufacturer's warranty. We can raise the case and chase it, but the replacement timeline belongs to them, not to us.

💡 Engineering Fact: That inspection has one visible side effect: browsers complain about certificates. Installing the firewall's own certificate on office machines during setup is a ten-minute job, and skipping it earns you a week of complaints.

🗒️ Where the Datasheet and Reality Differ for demanding workloads

In a crowded market street or a mall around Garifa, 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: 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.

🛠️ Shops, Counters and the Cabinet Behind the Billing Desk

Branch sites rarely have a proper rack, so these notes assume a wall cabinet, a counter and one plug point in Garifa.

🧰 On-Site Work - A Walkthrough across Kolkata

🔹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.
🔹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.

🧮 Feature List and Technical Detail for larger offices

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.

Throughput is published several ways and only one of them matters to you. Ask for the figure measured with intrusion prevention and encrypted inspection both running, because that is the state the appliance will actually work in day to day. The larger number on the front of a brochure is measured with almost everything switched off.

Board Layout, Shielding and Heat Paths Inside the Case

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).

Nobody in your office receives an attachment the world has not seen before on trust alone; it is opened in a sealed test room in the cloud first and released only when the verdict comes back. Files are also watched while they run in live memory, which is how malware written to look harmless to an ordinary scanner gets caught (Real-Time Deep Memory Inspection).

⚙️ SYSTEM EVALUATION & CHECKLIST

Turnkey UTM Firewall Appliance for Branch and Head Office Metrics Checklist near Garifa

🛠️ Workflow Setup

Internal lanes come next, accounts, guest WiFi, cameras and production kept apart, and computers pick up their new settings by themselves. Nobody walks desk to desk.

⚠️ Pitfalls to Avoid

Never leave guests and staff sharing a WiFi password. Whoever printed it on the menu card has effectively given the accounts server a public entrance.

🔌 Guidelines & Sizing

Use a patch panel and cut the leads to the length the run actually needs. A cabinet stuffed with three-metre cables is impossible to trace, and tracing is what you end up paying for at midnight.

📈 Upgrade Triggers

Every new outlet costs an engineer a full day on site to set up, and four more are opening this year.

Frequently Asked Questions

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. 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. Does it stop staff copying files onto a pen drive?

No. A USB stick never touches the network, so the firewall simply cannot see it. What it can do is stop the same file leaving by webmail, a personal cloud drive or a file-sharing site, and keep a record of who attempted it, which covers the routes people actually use. Locking USB ports properly needs software on each computer or a Windows policy, and we are happy to set that up as a separate piece of work. Anyone claiming a firewall on its own prevents data walking out of the building is overselling it.

Q. 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 Garifa before quoting and give you the honest number.

Q. 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.

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