Why does the office internet crawl every afternoon, even though you pay for a fast line? Nine times out of ten the firewall is the bottleneck, because it starts checking encrypted traffic and runs out of processing power by mid-day. The Sophos Next-Gen Firewall for Business Networks splits that work across two chips, so routine traffic flows straight through while the security scanning happens alongside it. We size and install these for offices in and around Ichapur, and we run the speed test in front of you before we hand the box over.
🧭 Annual Maintenance and Renewal for Sophos Next-Gen Firewall for Business Networks at multi-branch offices
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.
🔑 Why Businesses Pick Sophos Next-Gen Firewall for Business Networks when budgets are tight
Very few offices stay the same size for the working life of a firewall. Start with one internet line and forty users, and the same unit will later carry a second line, branch tunnels, remote staff and a guest network - licensed features rather than extra boxes. We size for headroom instead of for today's headcount, which is why our quotes for sites in Ichapur usually look one step ahead. When you do outgrow it, the configuration exports into a larger model rather than being retyped.
Ask any office that has owned a firewall for three years what they switched off. The honest answer is usually the scanning, because everything got slow - which leaves an expensive box doing the work of a router. The SophosNext-Gen Firewall for Business Networks keeps a second processor purely for routine traffic, so the main one is always free for the checks (Xstream architecture). Businesses around Ichapur buy the protection once and it stays switched on.
Export Houses and the Fake-Invoice Email Problem
A 60-machine garment unit near Ichapur shared one internet line between design, accounts and the camera recorder, and everything crawled from about eleven in the morning. We put in a SophosNext-Gen Firewall for Business Networks, fenced the camera recorder and the design machines off from each other and held back a fixed slice of the line for the ERP and the phones. The cameras kept recording and stopped competing with the billing team for bandwidth. The owner's summary a month later was that nobody had rung him about the internet since.
🛡️ SUPPORT AFTER THE INVOICE IS PAID
What Happens When Our Team Arrives
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:
▪Out-of-Hours Switchover from Your Old Firewall
▪Separate Lanes for Guest WiFi, CCTV and Accounts (VLANs)
▪Fibre Links Between Buildings, Fitted and Terminated (10GbE Transceivers)
▪Encrypted Website Scanning and Certificate Rollout
*Terms: labour, commissioning and after-hours attendance are billed items under a private service agreement, distinct from the product warranty.*
💡 Engineering Fact: Switch full security scanning on in most routers and the whole office slows down. This one avoids that by handing routine, already-checked traffic to a second chip while the main processor does the inspecting.

📚 Available Options and Typical Fit across Kolkata
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.
🔹 SIZE
About as big as a thick hardback book, so it fits on a shelf or inside a small wall cabinet.
🔹 POWER
Draws little enough that a small office UPS carries it and the modem straight through a cut.
🔹 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.
🔹 HEAT
Front-to-back cooling copes with a warm server room, though we still insist on a working AC and a clean filter.
🔹 IF THE POWER GOES
Some models carry bypass sockets that physically join the two sides on power loss, keeping the line alive until you get there.
🔹 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.
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.
🔹 VERY FAST PORTS
Twenty-five and forty-gigabit fibre sockets, so the firewall is never the narrow point between server rows.
🔹 WHO IT SUITS
Data centres, large campuses and companies holding tens of thousands of live connections at peak hour.
🔹 STORAGE
A pair of internal SSDs keep logs on the box itself, so a question about traffic from last month is answered from the appliance.
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.
🔹 WHAT STAFF SEE
Tally, the shared folder and the head office printer open exactly the way they do at the main location.
🔹 WHAT IT IS NOT
This is not a standalone firewall. It leans on the main appliance, so budget for both together.
🔹 BACKUP LINE
A second connection, including a 4G or 5G dongle, can be attached where the local broadband is unreliable.
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.
🔹 IF A PORT MISBEHAVES
You can spot the guilty port and shut it from the screen, instead of unplugging cables one at a time.
🔹 WHERE IT'S MANAGED FROM
The same cloud dashboard as the firewall, so one login covers both instead of two separate systems.
🔹 IF SOMEONE MAKES A LOOP
Plugging both ends of one cable into the same switch normally floods the whole office; the switch spots it and shuts that port.
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.
🔹 POWER
The network cable carries power up to the ceiling, so no electrician and no plug point above the false ceiling (PoE).
🔹 WALKING AROUND
Handover between units is quick enough that a call on WiFi survives a walk from the cabin to the shop floor.
🔹 WHO IT SUITS
Schools with tablets, hotels, co-working floors, and warehouses running handheld barcode scanners.
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.
🔹 WHO IT SUITS
CA firms in filing season, sales teams, and any business whose auditor asks who opened what and when.
🔹 IF A LAPTOP IS LOST
Access is cut from the dashboard in a minute. Nobody has to change the VPN password for the whole company.
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.
🔹 REPORTING
One list of every machine, whether its updates are current, and which computer is the repeat offender.
🔹 IF SOMETHING GETS THROUGH
A timeline shows where it came from - the attachment, the pen drive or the website - so the same door gets shut.
🔹 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).
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.
🔹 IF THE HARDWARE DIES
Support levels differ in how fast a failed unit is replaced. Choose that before you need it, not on the morning you do.
🔹 MULTI-YEAR TERMS
A three-year term fixes the cost and removes two rounds of buy orders, approvals and chasing.
🔹 WHAT PEOPLE REGRET
Letting it run dry for a couple of months to save money, then paying for reinstatement plus the clean-up afterwards.

🛠️ Workflow Setup
We agree the cutover window in advance, usually a Saturday evening or the hour after closing, and we tell you honestly how long the internet will be down. Twenty to forty minutes is typical.
⚠️ Pitfalls to Avoid
Do not run the standby unit's heartbeat cable through a switch. It goes straight from one box to the other, or both units will eventually decide they are in charge.
🔌 Guidelines & Sizing
Two power supplies only help if they are on two different circuits. Both plugged into one strip is a decorative feature, not redundancy.
📈 Upgrade Triggers
Someone in accounts opened a fake invoice email, and the only thing that saved you was that the attachment happened to be broken.
🧮 Capacity, Limits and Sizing Guide for larger offices
The family runs from small desktop units for one office up to rack appliances built for a head office of several hundred people and multiple internet lines. The operating system is the same across the range, so what your team learns on a small unit still applies on a large one. Growing is a change of model, not a change of habits.
Hardware and subscription are separate line items, and it is worth knowing which is which before you sign anything. The box keeps routing traffic when a subscription lapses, but the protection updates stop - a quiet failure rather than a loud one. We put the renewal date in writing and remind you well before it arrives.
🏆 CORE PARAMETER🔹 Sizes you can buyFanless desktop, 1U rackmount, 2U rackmount
🔹 Room temperature it tolerates0°C to 40°C (32°F to 104°F)
🔹 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
🔹 Unknown attachmentsOpened in a cloud sandbox before they reach a user
🔹 If a laptop gets infectedFirewall isolates it on its own - Synchronized Security heartbeat
🔹 If the main unit failsStandby takes over - Active-Passive or Active-Active HA cluster
Why the Same Model Behaves the Same Everywhere
If you pay for two internet connections, both should be earning their keep. Each one is measured continuously for loss, delay and wobble, and sessions move between them according to rules you set, so voice and billing get the healthy one. Branch tunnels rebuild themselves after a cut is repaired, with nobody logging in (SD-WAN).
Nearly everything your staff open now arrives encrypted, and a firewall that cannot look inside it is guarding a door somebody has propped open. That is the problem this range was built around: one processor does the inspecting while a second waves already-checked video, voice and cloud traffic through at full speed (dual-processor design).

TIME AND MONEY SAVED - IN PLAIN WORDS
WATCH-OUTS SPELLED OUT UPFRONT
✓"We turned virus scanning off because everything crawled" is the most common thing we hear when taking over an old box; here that switch can stay on for good (Xstream FastPath offload).
—Firmware updates drop sessions briefly. On a single unit that means a late-night window agreed with the people who actually work late.
✓Every branch firewall is configured and watched from one browser login, which starts to matter past the third site (Sophos Central).
—Automatic laptop isolation only works where the matching security agent is installed. Machines without it stay invisible to the firewall.
✓The Saturday-night infection that used to reach eight machines by Monday gets stopped at the first one, with nobody in the building (Synchronized Security heartbeat).
—Desktop models run on an external adapter with no second supply, so a failed adapter takes the office offline until a replacement reaches you.
✓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).
—VPN speed between branches is capped by the upload speed your ISP gives you. No firewall can invent bandwidth the line does not have.
✓You can see which application is eating the bandwidth at 3pm and cap just that one, without blocking the whole internet.
—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.
💡 Engineering Fact: A firewall remembers conversations, not just packets. Because it noted your request going out, the reply is allowed back in - and a packet claiming to answer a question nobody asked is dropped without ceremony.

🗒️ Lessons From Deployments That Went Wrong for demanding workloads
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: The settings screen and the traffic handling run as separate parts of the same system. That split is why saving a new rule at eleven in the morning does not interrupt the people already working.
🛠️ Fibre, Copper and What Plugs into What
A firewall usually fails for physical reasons long before it fails for security ones - heat, dust, bad power, or a cable somebody tugged while pulling out a server.
🛠️ Power and Backup - Site Rules for offices in Ichapur
🔹Give the HA pair its own cable. Run the heartbeat link directly between the two appliances on a dedicated port, never through a switch that somebody might reboot.
🔹Schedule the configuration backup on day one and send an encrypted copy off the site - the day you need that file is the day the box is dead.
🔹Feed the two power supplies from two different circuits, both behind an online UPS, so a single trip during the usual evening voltage swings does not take the gateway down with it.
Frequently Asked Questions
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. We are a 20-person office. Is this overkill for us?
Not really - the model matters far more than the brand. A small office on an entry-level unit gets the same scanning engine as a large one; it simply handles fewer users and less traffic. Overkill is buying a rack-sized box with modules you will never switch on, which does happen. Tell us your staff count, your line speed, whether you host anything in-house, and how many branches there are, and we will point at the smallest thing that fits comfortably.
Q. Who owns the settings and passwords afterwards?
You do. At handover you get the admin login, the licence details, the configuration backup file, and a written note of what was set up and why. We keep a copy so we can help you quickly, but the equipment and the manufacturer account stay in your name, and nothing is tied to us if you move to another vendor later. Ask for exactly this in writing from whoever you buy from - a surprising number of small offices cannot get into their own firewall.
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 Ichapur.
💡 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.
