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 Shibpur.
💼 SonicWALL Supply and Aftercare for Business Buyers in Shibpur
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 Shibpur 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).
🤝 What You Get That Cheaper Options Skip in Shibpur
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 Shibpur usually find the licence conversation more useful than the hardware one.
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.
Design Studios Moving Very Large Files across Kolkata
A multi-brand car dealership on the outskirts of Kolkata ran the showroom, the workshop tablets and the spares counter on one flat network, and the dealer management system stalled whenever the service team uploaded job photographs. We separated the three areas and reserved a fixed share of the line for the dealer system and the phones. Customer Wi-Fi in the lounge now sits on its own lane and cannot reach anything internal. The service manager has stopped keeping a paper copy of every job card.
🛡️ RACK WORK, LABELLING AND CABLE ORDER
Who Comes to Site and What They Do
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:
▪A Standby Box So One Failure Does Not Stop Work
▪Access Point and Managed Switch Setup from One Console
▪Sending a Pre-Set Box to a New Branch (Zero-Touch)
▪Moving Off Your Old Firewall Without Downtime
*On scope: questions raised after the settling-in period become a paid engagement with us, not a ticket on the vendor's helpdesk.*
💡 Engineering Fact: Your whole office looks like one address from the outside, with dozens of machines sharing it. That is also why a camera recorder plugged straight into the internet, with no firewall in front, gets found by automated scanners within hours.
🧰 SUPPORT & SPARES
A dead gateway on a Saturday is not the moment to start hunting for a phone number. Yearly support covers a stated response time, firmware patching and a standby unit for sites around Shibpur.
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.
🔹 WHEN YOU GROW
A rack tray is available later, for the day the box has to move off the shelf and into a cabinet.
🔹 WIFI BUILT IN
Several models carry their own wireless, which saves buying a separate access point in a one-room office.
🔹 POWER DRAW
Modest enough that a small UPS carries the firewall, the modem and the switch straight through a cut.
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.
🔹 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).
🔹 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.
🔹 TWO POWER FEEDS
Fit the second supply and run it from another circuit. The day an electrician isolates one board, the network stays up.
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.
🔹 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.
🔹 MEMORY-LEVEL CHECKS
Unknown files are watched while they actually run in memory, which catches the tricks written to fool an ordinary scanner (RTDMI).
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.
🔹 IF A UNIT DIES
Courier a replacement. It collects the same configuration by itself, so the branch is usually back on the same day.
🔹 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.
🔹 BUILD
Metal case, low power draw, and it copes with a dusty stores room far better than the plastic router the ISP left behind.
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.
🔹 MANAGED FROM
The firewall itself acts as the wireless controller, so there is no second box and no second console to log into.
🔹 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.
Managed Switches on the Same Console as the Firewall
Switches that report to the same screen as the firewall, so ports, cameras and phones are handled from one login. For offices past the stage of stacking small unmanaged boxes under a desk.
🔹 CHANGING A DESK
Moving somebody from accounts to sales becomes a setting, not a trip to the rack with a screwdriver and a torch.
🔹 SEPARATE LANES
A camera recorder and a staff laptop can share cabling and still be unable to see each other, which is what setting up VLANs properly buys you.
🔹 WHAT IT'S FOR
Replacing the chain of little unmanaged switches that has grown under the desks, one added per problem over five years.
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.
🔹 RECORDS
Who connected, when, and to which server - the report exists whether or not anybody ever asks to see it.
🔹 WHEN NOT TO BOTHER
If everyone works in one building and nobody travels, put the money into the firewall instead.
🔹 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.
🔹 REPORTS
Monthly summaries of what was blocked and where the day's bandwidth went, in a shape a director will actually read.
🔹 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.
🔹 WHEN IT EXPIRES
No alarm sounds and nothing goes dark. The unit simply stops learning about anything new while everyone assumes it is still working.
🔹 MULTI-YEAR TERMS
Paying for three years at once holds the price still and removes two more rounds of quotations, approvals and reminder calls.
🔹 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.

📌 What Happens When Everyone Logs In at Once in Shibpur
Both columns are worth reading before you settle on a model.
EVERYDAY WINS SUMMED UP
WHAT NEEDS SETTING UP FIRST - BEFORE YOU SIGN
✓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.
—Fibre ports arrive empty. Transceivers or DAC cables are ordered separately, and a mismatched part will simply refuse to come up.
✓Opening a branch in a town where you know nobody used to mean sending an engineer for two days. The box is couriered instead and the shop manager plugs it in (Zero-Touch Deployment).
—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.
✓Large engineering drawings and installer files are not skipped for being too big, because there is no size cut-off on the scan (RFDPI).
—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).
—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.
✓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).
—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: 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.

🏢 Labelling & Documentation - How It Works in Shibpur
🔹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.
🗒️ Capacity, Limits and Sizing Guide in Shibpur
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.
🏆 CORE PARAMETER🔹 Network socketsCopper 1GbE on every model, 2.5GbE multi-gig on the TZ 570 and 670, and 10GbE SFP+ fibre on the larger rack units - the mix depends on the model ordered
🔹 Threat updatesAutomatic feeds from the vendor's threat network, nothing to download by hand
🔹 If the box diesActive-Standby or Active-Active pair with stateful failover
🔹 Encrypted site scanningTLS 1.3 inspection with hardware acceleration (DPI-SSL)
🔌 Second power supplyOptional on smaller rack models, standard and hot-swappable on the large ones
🔹 How it scansThe whole stream is reassembled and read, with no cap on file size (RFDPI)
🔹 Linking your branchesIPsec site-to-site tunnels, SSL VPN for staff, Secure SD-WAN across lines
What Happens on the Production Line
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.
✉️ SUPPORT DESK
Coordinate custom hardware configurations, AMC maintenance contracts, and site engineering visits directly with authorized integration desks.
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: 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.

🛠️ Workflow Setup
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.
Frequently Asked Questions
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 Shibpur before quoting and give you the honest number.
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. 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. 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. 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: 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.
