Work out what one day of a stopped office actually costs you: salaries paid for nothing, dispatches missed, a GST filing that slides past its date. Set that beside the price of a properly sized firewall and the argument tends to finish itself. Ransomware rarely arrives looking like an attack; it walks in through an encrypted website nobody inspected, spreads sideways, and locks the accounts server on a Saturday night. The Next-Gen Firewall for Business Networks looks inside those encrypted sessions and pulls an infected machine off the network by itself, within seconds.
📍 Annual Maintenance and Renewal for Sophos Next-Gen Firewall for Business Networks across Kolkata
Your guest Wi-Fi password has been on a whiteboard for two years, and the camera recorder shares a network with the accounts computer. This appliance splits one flat office network into separate lanes - staff, guests, cameras, production machines - so trouble in one lane cannot wander into another (VLAN zone policies). Visitors still get internet; they simply cannot see your servers. It is the cheapest tidy-up available to most offices and it takes an afternoon.
An unsupported firewall is a locked door whose key everyone has already copied - from the outside it still looks fine. Moving to a current SophosNext-Gen Firewall for Business Networks puts you back on supported firmware, live protection updates and a warranty you can actually claim. We copy your existing rules across, remove the dead ones, and do the switch in the evening so the morning shift finds nothing changed. Offices across Kolkata usually get a rule-by-rule handover document before the old unit leaves the rack.
💡 The Case for Doing It Properly Once across Kolkata
Some businesses can lose an hour. A dispatch desk, a hospital front office or a trading room cannot. Two units can be paired so the standby picks up the live sessions the instant the first one stops, fast enough that a call in progress stays up (Active-Passive HA). Most customers start with one unit and add the second at the next budget cycle, and the pairing is designed to be added later.
Running four branches used to mean four different people making four different mistakes. Every unit reports into one console, so you push the same rules everywhere, see which branch has which problem, and update firmware overnight from your own desk. A new site can be sent the box, plugged into power and internet by anyone on site, and configured remotely. Retail chains and diagnostic labs spread across Kolkata are the usual beneficiaries.
Keeping Four Branches on the Same Rules across Kolkata
A school with roughly nine hundred students found its online exam portal timing out every afternoon, which turned out to be a hostel's worth of video streaming on the same line. We deployed a SophosNext-Gen Firewall for Business Networks with separate staff, student and guest networks, and capped entertainment traffic during school hours only. The very next assessment week finished on time. The IT teacher now changes the rules himself from a browser rather than phoning anyone.
🛡️ HOW WE WORK ON SITE
How We Set Up and Hand Over a Firewall
We expect a few calls in the first fortnight after handover, and we plan for them. A blocked website, a vendor VPN that needs an exception, a printer that stopped talking to the accounts machine - all normal, all part of the commissioning period rather than billed as fresh visits. Past that window, support runs under whichever contract you have chosen.
What you can hand over to us, on a per-job or annual contract basis:
▪A Bouncer for Your Website and Mail Server (WAF)
▪Firewall Supply, Setup and Commissioning
▪Fibre Links Between Buildings, Fitted and Terminated (10GbE Transceivers)
▪Quarterly Rule Review and Clean-Up of Dead Policies
*Note: every site visit, configuration change and troubleshooting session listed here is a paid service, quoted in advance, and separate from any support you receive directly from the manufacturer.*
💡 Engineering Fact: On the larger models, two power packs share the load, and if one input dies the other takes the whole thing on instantly. In practice that input usually dies because of a tripped circuit or a wrongly pulled plug.

📦 Available Options and Typical Fit for growing companies
The table below covers sizes, interfaces and what fits which office:
Desktop Firewalls for Small Offices and Shops
Small, silent boxes that sit on a shelf and guard the internet line of a five to fifty person office. Suits clinics, showrooms, CA practices and single-branch businesses.
🔹 NOISE
No fan inside. It can live in a reception area or a director's cabin and nobody hears it.
🔹 WHAT IT'S FOR
Offices, clinics and showrooms of roughly five to fifty people sharing one or two internet lines.
🔹 GUEST WIFI
Visitors and staff run on different networks, so a guest laptop never sees the accounts machine (VLAN).
Rack-Mount Firewalls for Head Offices
One-rack-unit appliances for a head office, hospital or college where a few hundred people are on the network all day. Built to sit in the server cabinet you already have.
🔹 SPARE POWER
A second power supply can be fitted and fed from a different circuit, so one tripped MCB does not take the office offline.
🔹 LOAD
Antivirus, intrusion checks and encrypted-site scanning can all run together without the branch tunnels slowing to a crawl.
🔹 IF IT FAILS
Two units run as a pair with one on standby, and the handover is fast enough that a video call carries on (HA cluster).
Large Firewalls for Data Centres and Campuses
The heavy two-rack-unit units, for data centres, big campuses and companies pushing tens of thousands of connections at once. Everything that can fail is doubled up.
🔹 WHO IT SUITS
Data centres, large campuses and companies holding tens of thousands of live connections at peak hour.
🔹 VERY FAST PORTS
Twenty-five and forty-gigabit fibre sockets, so the firewall is never the narrow point between server rows.
🔹 SIZE
Two rack units, considerably heavier, and it needs proper rails in a full-depth cabinet rather than a shelf.
Easy to set up Branch Boxes (RED) for Small Sites
For the two-person sales office, the godown, the site cabin. You courier the box, somebody plugs it in, and that location joins the head office network by itself.
🔹 SETUP
Nobody technical travels. The box is couriered, a local hand plugs in power and internet, and it fetches its own settings.
🔹 WHAT STAFF SEE
Tally, the shared folder and the head office printer open exactly the way they do at the main location.
🔹 IF IT FAILS
Swap the unit. The replacement pulls the same configuration down on its own, so there is nothing to set up again.
Managed Network Switches for the Server Room
For offices that have outgrown cheap unmanaged switches and want to see which port is causing the trouble. They also feed power to cameras, phones and access points down the same cable.
🔹 WHAT'S EXTRA
Check the total watts on offer before ordering. Thirty cameras on one switch will use up a small power budget quickly.
🔹 LANES
Cameras, billing machines, guest WiFi and staff laptops stay apart on the same physical cabling (VLANs).
🔹 POWER DOWN THE CABLE
Access points, IP phones and cameras run off the network cable itself, so no adaptor is needed at ceiling height (PoE).
WiFi Access Points for Offices, Schools and Warehouses
Ceiling-mounted units that give a whole floor usable WiFi instead of one router struggling from a corner. Made for buildings where dozens of devices connect at the same time.
🔹 COVERAGE
Plan by walls, not by wattage. A brick partition or a lift shaft eats more signal than most people expect.
🔹 WHERE IT'S MANAGED FROM
One cloud console shows every unit, who is connected and which one is the busiest.
🔹 GUEST WIFI
Visitors get their own name and password, on their own lane, with a login page and a daily expiry if you want one.
Secure Remote Access for Staff Working from Home
Lets a person open the one office application they need - from home, from a client site, from a hotel - without dropping their laptop inside your whole network.
🔹 WHAT'S EXTRA
Licensed by number of users, so a five-person accounts team is paid for as five, not as the whole staff.
🔹 WHAT IT'S FOR
Staff at home, on the road or at a client site who need the office server without the office network being wide open.
🔹 WHO IT SUITS
CA firms in filing season, sales teams, and any business whose auditor asks who opened what and when.
Antivirus for Laptops and Servers That Talks to the Firewall
Protection on the machines themselves, wired to the firewall so the two act together. Useful for any office where staff install their own software or carry pen drives in.
🔹 THE PART PEOPLE LIKE
If a machine gets infected, the firewall drops it off the network within seconds, without waiting for anyone to notice (Synchronized Security).
🔹 WHAT IT'S FOR
Guarding the laptops, desktops and servers themselves, rather than only the door they sit behind.
🔹 WHAT IT REPLACES
The free antivirus that quietly expired two years ago and the paid one nobody renewed after the IT person left.
Licence Renewals and Support Subscriptions
The yearly subscription that keeps the threat updates, web filtering and support alive. This is the part most buyers forget until the day it lapses.
🔹 WHAT PEOPLE REGRET
Letting it run dry for a couple of months to save money, then paying for reinstatement plus the clean-up afterwards.
🔹 BUNDLES
One combined subscription covers most of the protection at a better rate than buying the modules one by one.
🔹 AUDITS
An auditor checking your security controls will ask for proof the subscription is live. A lapsed one is a finding.

📝 Lessons From Deployments That Went Wrong across Kolkata
The number to size on is throughput with inspection running, not the large figure on the front of the brochure. I have replaced plenty of perfectly good firewalls that were simply one model too small, and the symptom is always identical: features disabled one at a time until the thing is an expensive router. Ask for the figure with intrusion prevention and encrypted inspection both enabled, then leave headroom above it.
Buying separate boxes for web filtering, remote access and intrusion prevention leaves you with three renewal dates, three consoles and three vendors pointing at each other. One appliance with one policy list is easier to run and much easier to hand over.
An internet provider's optional security add-on filters at their end, on their terms, with no report you can put in front of an auditor and little control over what is allowed for whom. Owning the box means owning the rules and the logs.
💡 Engineering Fact: Fibre between two buildings works by shining a laser down glass thinner than a hair. The common short-range module reaches about 300 metres, and picking the wrong one for a longer run is the cheapest mistake in networking.

TIME AND MONEY SAVED - THE HIGHLIGHTS
WATCH-OUTS - THE HONEST VERSION
✓The fake invoice from a supplier's hijacked mail account arrives over https, and a gateway that cannot open encrypted pages hands it straight to your accounts desk - this one opens it (TLS 1.3 inspection).
—Traffic pushed through anonymising proxies or unmanaged tunnels sits outside these controls, so policy alone will not stop a determined employee.
✓Hosting your own website or mail server is what turns your office address into a target; a filter in front of it absorbs the standard break-in attempts before they reach the server (Web Application Firewall).
—A proper 19-inch rack with front-to-back airflow is expected. A firewall balanced on a cupboard shelf runs hot and dies early.
✓Selected rack models keep the wire connected even if the appliance loses power, so a production line does not halt (bypass ports).
—The browser-based remote access screen leans on the user's own laptop and connection. On an old machine over patchy mobile data it feels sluggish.
✓Branches join the head office over an encrypted tunnel, so a shared ERP behaves as if everyone sat in one building (site-to-site IPsec).
—Central cloud reporting needs a working outbound connection. At a site with a flaky line, expect gaps in the dashboards.
✓Threat lists refresh on their own through the day, so protection never depends on somebody remembering to update it.
—Web application firewall rules need tuning in the first fortnight, or they will block a legitimate in-house script and the firewall will get the blame.
💡 Engineering Fact: Your office has one public address on the internet and dozens of machines behind it. The firewall rewrites addresses on the way in and out to keep that straight, which is also why putting a camera recorder directly online is asking for trouble.

📊 Capacity, Limits and Sizing Guide for offices in Malda
Rack models take two power supplies and can be paired with a second appliance, so neither a failed power feed nor a failed unit has to stop the office. Failover carries the live sessions across, which is the difference between a blip and a room full of dropped calls. Desktop models trade that redundancy for size and price, and for a single office in Kolkata that is usually the right trade.
On the software side you get web and application filtering, intrusion prevention, mail scanning, a cloud test room for unknown files, and a filter that can sit in front of your own web or mail server. All of it is configured in one place rather than across five separate products. Rules can be written per user group, which is what keeps them readable a year later.
🏆 CORE PARAMETER🔹 Room temperature it tolerates0°C to 40°C (32°F to 104°F)
🔹 Speed with scanning onA dedicated chip does the inspection, so the drop is far smaller than on an ordinary router - we size the model against the traffic you will actually scan
🔹 If the main unit failsStandby takes over - Active-Passive or Active-Active HA cluster
🔹 Sockets on the boxgigabit copper as standard, with 2.5-gigabit copper and 10-gigabit fibre on the models that offer them - we confirm the port list against the model you order
💾 Log storage on boardGood for large-scale setups SSD for local reporting and audit trails
🔹 If a laptop gets infectedFirewall isolates it on its own - Synchronized Security heartbeat
Why the Same Model Behaves the Same Everywhere
If a computer in your office starts behaving like an infected one, you should not have to wait for somebody to raise a ticket. The protection software on the machine and the gateway talk to each other continuously, so an unhealthy machine is cut back within seconds and the alert names both the machine and the person using it (Synchronized Security).
Open one login and you see every site you run, with the same rules, the same scheduled firmware updates and a stored copy of each configuration. A new branch joins the network without an engineer travelling there to type anything in, which is the difference between a week and an afternoon when you open shop number five (cloud console).

The points below cover where the unit sits, how it is powered and how it is wired, in roughly the order an engineer would work through them.
📋 Rollout Across Branches - Site Rules for offices in Malda
🔹Before switching on inspection of encrypted sites, push the firewall's certificate out to every company computer through Group Policy. Do that first and you save yourself a morning of browser warnings.
🔹Rack it with a gap. Leave a clear 1U above and below the appliance so hot air can escape - in the unventilated cabinets common around Malda, a unit wedged between two servers will throttle by May whatever the datasheet promises.
🔹Reserve bandwidth for the phones and for Tally or your ERP before you open general internet access; loosening a limit later is far easier than explaining choppy calls.

🛠️ Workflow Setup
If you bought a standby unit, we connect the pair, pull the power from the main one deliberately, and let you watch the second take over while you are standing there.
⚠️ Pitfalls to Avoid
Nobody writes the passwords down, and then the engineer who set it up changes jobs. Get credentials in writing and keep them somewhere two people can reach.
🔌 Guidelines & Sizing
Buy solid copper Cat6, not the cheaper copper-clad aluminium sold under the same label. The thin stuff heats up and resists current, and the drops it causes look exactly like an internet fault.

Your bank, your largest customer or an auditor has begun asking for a written network security policy and logs that back it up.
Frequently Asked Questions
Q. Can guest WiFi, CCTV and accounts be kept apart?
Yes, and it is one of the more valuable things to do. The network is split into separate lanes so a visitor's phone, the camera recorder and the accounts server cannot see one another, with the firewall inspecting anything that crosses between them (VLAN segmentation). This is what stops a single infected machine from wandering across the whole office. Cameras and other smart devices deserve their own lane in particular, because they are rarely updated. It needs some planning of the switch layout, which is why we ask for a site visit first.
Q. How do we connect branch offices back to head office?
Two ways, depending on the branch. A small outlet gets a compact plug-in unit that dials home by itself the moment it has any internet - no engineer trip, no configuration done at the branch (Remote Ethernet Device). A larger branch with its own firewall gets a permanent encrypted link between the two sites instead. Either way the branch is treated as another wing of your network, so head-office filtering and rules apply there too, whether it is one shop or twenty across Kolkata.
Q. What happens if it stops working on a Sunday?
Ring the support number and we start on it the same day, usually remotely, and for most faults we can talk someone through a temporary bypass so Monday morning is not a write-off. If the hardware itself has died, replacement runs through the manufacturer warranty, and the speed of that depends entirely on which support pack you bought - a next-business-day pack and a plain return-to-base pack are very different waits. We hold common spares on the shelf, but we will not pretend a unit can be at your gate within two hours. If a few hours offline is genuinely unaffordable, the honest answer is a standby unit, not a faster courier.
Q. How long does installation take, and will the office be shut?
A single-site install is generally a one-day job, and the only real interruption is the ten to twenty minutes when your internet connection moves across to the new box. We do that changeover early morning, after hours, or on a Saturday - whichever hurts least. Sites with several floors, more than one internet line, or a big pile of existing rules take two or three days, because rules have to be rebuilt and tested rather than copied over blindly. The cutover window is agreed with you in writing before anyone turns up in Malda.
Q. Our internet keeps dropping. Will this fix it?
It will not repair a bad line, but it can stop the drop from stopping work. Connect two links - a fibre leased line and a broadband or 4G backup, say - and the box watches both and shifts traffic onto the healthy one on its own (SD-WAN). Calls, Tally sessions and cloud apps ride whichever link is cleanest at that moment. If a single line is dropping five times a day, the real fix is a conversation with your ISP; this only makes the drops survivable.
💡 Engineering Fact: After the first few packets of a video call or a cloud ERP session, the firewall recognises the conversation and waves the rest through at full speed instead of re-checking every packet of a stream it has already cleared.
