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 Girish Park, and we run the speed test in front of you before we hand the box over.
📍 Onsite Installation and Staff Training for Sophos across Kolkata
The auditor asked who can reach the accounting server and from where, and nobody could answer in writing. This gateway records every connection with the user's name attached, so the answer becomes a report instead of a guess. Policies are written per group - accounts, sales, guests, visitors - which keeps them readable a year later by whoever inherits them. That paperwork is what turns a two-week audit scramble into an afternoon.
Almost every site your staff open is now encrypted, and an older firewall waves that traffic straight through unopened. A SophosNext-Gen Firewall for Business Networks can look inside those sessions for hidden malware and still keep pages loading quickly, because the decryption work is done in hardware (TLS 1.3 inspection). You choose what gets opened and what stays private, so banking and medical sites can be left alone. Without it, most of what enters your office is never examined at all.
💡 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 are an independent integrator, not the manufacturer's helpdesk, and it is worth being clear about that up front. Our engineers configure the appliance, connect it to your switches, test the failover by pulling a cable rather than trusting the manual, and stay reachable the next working morning. Anything that cannot be fixed in software goes to Sophos through the proper channel, and you are told exactly where it stands.
Services delivered on site and remotely, priced up front:
▪Fibre Links Between Buildings, Fitted and Terminated (10GbE Transceivers)
▪Encrypted Website Scanning and Certificate Rollout
▪Infected Laptops Cut Off Automatically (Synchronized Security)
▪Annual Maintenance Contracts and Response-Time Cover
*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: 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.

📦 Pick the Right Variant Without Overspending across Kolkata
Read across for chassis size, power options and fibre support:
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.
🔹 POWER
Draws little enough that a small office UPS carries it and the modem straight through a cut.
🔹 SIZE
About as big as a thick hardback book, so it fits on a shelf or inside a small wall cabinet.
🔹 TWO INTERNET LINES
Keep fibre and a broadband backup plugged in together; when one drops, the switch across happens on its own (SD-WAN).
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.
🔹 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.
🔹 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).
🔹 ROOM TO GROW
A slot on the front accepts an add-on module - more copper ports, faster ones, or fibre - when the network expands (Flexi Port).
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.
🔹 BUSY NETWORKS
Sized for the case where thousands of people, cameras and machines all hold connections open at the same moment.
🔹 WHO IT SUITS
Data centres, large campuses and companies holding tens of thousands of live connections at peak hour.
🔹 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.
🔹 WHAT IT IS NOT
This is not a standalone firewall. It leans on the main appliance, so budget for both together.
🔹 WHAT IT'S FOR
Very small sites - a warehouse office, a godown, a two-person branch - that still need to be on the head office network.
🔹 BUILD
Metal body, low power draw, no fan, so it survives a dusty stores room far better than a plastic consumer router.
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.
🔹 WHO IT SUITS
Schools, hotels, hospitals and factories - anywhere the camera and phone count keeps climbing.
🔹 WHAT'S EXTRA
Check the total watts on offer before ordering. Thirty cameras on one switch will use up a small power budget quickly.
🔹 LONG RUNS
Fibre uplinks reach an upper floor or a second building without the speed loss a long copper run brings.
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.
🔹 WHERE IT'S MANAGED FROM
One cloud console shows every unit, who is connected and which one is the busiest.
🔹 WALKING AROUND
Handover between units is quick enough that a call on WiFi survives a walk from the cabin to the shop floor.
🔹 SPEED
Newer WiFi 6 units are about serving many devices at once rather than one device very fast, and that is the difference a crowded office actually feels.
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.
🔹 RECORDS
Each session is logged by person and by application, which is normally the exact evidence an audit wants.
🔹 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.
🔹 WHAT THE USER DOES
Signs in with the usual office email and password, plus a code on the phone as a second step.
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.
🔹 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.
🔹 WHAT'S EXTRA
Mail and mobile device protection are separate add-ons and are worth pricing at the same time.
🔹 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.
🔹 WHEN YOU OUTGROW IT
Ask before you renew if headcount has doubled. Sometimes a bigger unit with a fresh term works out better than renewing the old one.
🔹 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.
🔹 AUDITS
An auditor checking your security controls will ask for proof the subscription is live. A lapsed one is a finding.

📝 Field Testing and What It Told Us across Kolkata
The first thing I check on an inherited firewall is whether encrypted traffic is being inspected at all. Nine times out of ten it was turned off because the old box could not cope, which means every https download for the last three years went in unopened. On the SophosNext-Gen Firewall for Business Networks the decryption work sits on dedicated silicon, so you can switch it back on and still have people in Girish Park saying browsing feels the same. Start with one department, watch for complaints, then widen it.
Older security appliances did every job on one general-purpose processor, which is why switching scanning on used to halve the speed. Moving routine traffic onto a separate chip is the main practical difference you will actually feel day to day.
Antivirus on each computer only acts once a file has already landed on the machine. A gateway checks it on the way in, and also covers the printers, cameras and shop-floor equipment that cannot run antivirus at all.
💡 Engineering Fact: Between the firewall and the switch, a short direct-attach cable beats a copper 10-gigabit port on all three counts: it costs less, adds almost no delay, and runs far cooler in a crowded cabinet.

FEWER HEADACHES - THE HIGHLIGHTS
WHERE IT FALLS SHORT - THE HONEST VERSION
✓Threat lists refresh on their own through the day, so protection never depends on somebody remembering to update it.
—Central cloud reporting needs a working outbound connection. At a site with a flaky line, expect gaps in the dashboards.
✓Audit questions get answered with readable summaries of who went where, not a pile of raw log files.
—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.
✓An ageing core switch and a new fibre run can both plug into the same box, so nobody is forced into replacing the switch in the same month (port mix varies by model).
—In-depth logging fills the internal disk if nobody sets rotation or ships the logs off the box.
✓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).
—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.
✓Login names come from your existing Microsoft accounts, so reports name people instead of IP addresses (Active Directory, LDAP, SAML 2.0).
—Running BGP or OSPF routing is genuine network engineering. Budget for a competent hand on cutover day instead of treating it as a weekend experiment.
💡 Engineering Fact: Protected laptops send the firewall a one-line health note every few seconds. The moment one of those notes turns red, the firewall stops that machine talking to anyone else on the network.

🛠️ Where the Box Should Actually Sit: Rack and Room Notes for Girish Park
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.
🛠️ Go-Live Day Step by Step for growing offices
🔹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.
📊 How Much It Handles Before It Slows Down for offices in Girish Park
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.

Optical Port Assembly and High-Speed Board Tolerances
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).

🛠️ 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.
Frequently Asked Questions
Q. We already have antivirus on every computer - why do we need this too?
Antivirus acts once something has already landed on a machine; this stops a good deal of it further back, at the office door. It also does jobs antivirus cannot: blocking the sites that hand out malware, controlling what staff can download, and cutting an infected laptop off from everyone else. Where the two talk to each other, a red flag raised by the laptop makes the firewall separate that machine within seconds (Synchronized Security). They are layers, not alternatives.
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 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 Girish Park.
Q. Do we have to keep paying every year?
Yes, and it is fair to know that before you sign. The box is bought once, but the protection running on it - virus updates, web filtering categories, the sandbox, the right to call support - renews annually or in multi-year blocks. Let it lapse and the firewall still passes traffic, but it stops learning about anything new, which is close to useless against a current threat. A three-year bundle bought up front usually works out cheaper per year than renewing one year at a time.
Q. Someone in accounts opened a bad attachment last year. Would this have caught it?
Very likely, though no one honest says always. Unknown files arriving from outside are opened first inside a sealed test space away from your network, and if the file starts encrypting things or calling home, it never reaches the mailbox (sandboxing). What it cannot do is stop a staff member typing the company bank password into a convincing fake login page - that is staff training and two-factor login, not hardware. Think of it as removing most of the risk, not all of it.
💡 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.
