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 Garia.
📍 SonicWALL Supply and Aftercare for Business Buyers across Kolkata
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 Garia 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).
💡 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 Garia 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
It is worth being blunt about who we are: an independent supplier and integrator, not the manufacturer's helpdesk. Our team racks the unit, cables it into your switches, and proves the standby really does take over by unplugging the primary in front of you rather than quoting a datasheet line. If a fault turns out to be hardware, we open the warranty case with SonicWALL and keep chasing it, though the replacement clock is theirs.
A short menu of what customers ask us to take off their hands:
▪Automatic Switching between Two Internet Lines (SD-WAN)
▪Access Point and Managed Switch Setup from One Console
▪Testing Unknown Files Before They Reach Staff (Capture ATP)
▪Keeping Guest WiFi, Cameras and Billing Apart (VLAN Zones)
*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.

📦 Pick the Right Variant Without Overspending near Garia
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.
🔹 WIFI BUILT IN
Several models carry their own wireless, which saves buying a separate access point in a one-room office.
🔹 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.
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.
🔹 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+).
🔹 RULES FOLLOW THE PERSON
Because the firewall reads who signed in to Windows, a manager gets manager access from any desk in the building (Single Sign-On).
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.
🔹 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.
🔹 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.
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.
🔹 IF THE LINE DROPS
A second broadband connection, or a 4G or 5G dongle, carries that branch until the main link comes back.
🔹 IF A UNIT DIES
Courier a replacement. It collects the same configuration by itself, so the branch is usually back on the same day.
SonicWave WiFi Access Points for Full Floor Coverage
SonicWave units screwed to the ceiling so the signal reaches the far end of the floor. For any building where the WiFi works near the router and nowhere else.
🔹 CHECK BEFORE ORDERING
Where the network cabling already runs. Pulling fresh cable through a finished ceiling costs more than the access point does.
🔹 PLANNING
Signal is eaten by brick walls, lift shafts and steel racking, so units get placed by the building's layout rather than by floor area.
🔹 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.
🔹 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.
🔹 ONE LOGIN
The switch shows up in the same management console as the firewall, so ports and security rules are dealt with together.
🔹 BETWEEN BUILDINGS
Copper stops being useful at about ninety metres. Past that the uplink goes on fibre, and these units take fibre directly.
Cloud Edge: Office Access for Staff Working from Home
Lets a person reach the one office server they need from home, a hotel or a client's site, without their laptop landing inside everything you own. Bought per person, not per building.
🔹 WHAT IT'S FOR
The accounts person finishing a return from home, and the sales engineer who needs the price list while sitting in a client's office.
🔹 RECORDS
Who connected, when, and to which server - the report exists whether or not anybody ever asks to see it.
🔹 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.
🔹 WHAT IT WILL NOT DO
It does not replace somebody reading the reports. The console tells you; it does not decide for you.
🔹 WHAT IT'S FOR
Companies with several sites, where logging into each firewall separately has stopped being realistic.
🔹 ONE CHANGE, EVERY SITE
A new blocking rule reaches twenty branches at once, instead of being typed twenty times with the twentieth forgotten.
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 YOU ARE PAYING FOR
Not the metal box. You are paying for current threat information, category lists, and somebody to call when it misbehaves.
🔹 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.
🔹 AUDITS
Show an assessor a lapsed subscription and it goes straight into the report as a finding, whatever the firewall itself is doing.

🛠️ 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.
📝 Honest Pros and Cons From the Bench across Kolkata
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 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.

EVERYDAY WINS - THE HIGHLIGHTS
WHAT NEEDS SETTING UP FIRST - THE HONEST VERSION
✓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).
—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.
✓The eleven o'clock slowdown is rarely the internet line. The traffic report names the application eating it, and that one habit can be held back without touching anyone's work.
—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.
✓One click on a convincing invoice page is how most incidents begin; fake payment pages and spoofed download sites are blocked before the click matters (content filtering).
—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.
✓At a site you cannot simply switch off, a failed power supply on the rack models is replaced while the box keeps running (hot-swap PSU).
—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.
✓When the fibre drops in the middle of billing, the second line picks the traffic up on its own rather than waiting for someone to notice (Secure SD-WAN).
—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.
💡 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.

📊 How Much It Handles Before It Slows Down for offices in Garia
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.

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.

🏢 On-Site Work - How It Works in Garia
🔹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.
Frequently Asked Questions
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. 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 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. 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. 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.
💡 Engineering Fact: The number on a firewall's spec sheet that runs out first is usually not speed but the count of simultaneous connections. Fifty cameras and a hundred IP phones hold thousands of them open all day while doing very little.
