The throughput figure printed on a datasheet is measured with almost every security feature switched off. Real numbers land far lower once virus scanning, intrusion prevention and encrypted traffic checks all run together, which is exactly how you will be running it. We keep units on the bench and load them properly before quoting, so the model we recommend has room to grow rather than a marketing number behind it. That single habit has saved a fair few clients from a box they would have outgrown inside a year.
🤝 Sophos Supply and Aftercare for Business Buyers around Kamarhati
The video call freezes every time somebody in accounts starts a large upload, and by four in the afternoon nobody trusts the internet at all. A SophosNext-Gen Firewall for Business Networks sits between your office and your internet line and decides what gets priority, so meetings and accounting traffic go first while bulk downloads wait their turn. The security checks run on a separate chip, which is why speed does not collapse the moment you switch scanning on (Xstream FastPath offload). We size the unit against your real user count and install it for offices in and around Kamarhati.
One salesman's laptop picked up something from a pen drive, and by lunchtime three other machines were behaving strangely. The firewall talks continuously to the protection software on each computer, so a machine that starts misbehaving is cut off the network within seconds (Synchronized Security). Nobody has to notice it, ring IT and wait - the box does that part on its own. That single behaviour is why most of our customers in Kolkata stop treating antivirus as the whole plan.
✅ Benefits Your Accounts Team Will Notice throughout Kolkata
You already own a Windows login system, a set of switches and possibly a Wi-Fi controller you would rather not replace. This gateway reads your existing office logins, so rules follow the person rather than whichever machine they sat at, and it drops into your current switch layout without re-cabling the floor. Nothing else has to be ripped out on day one. That is what makes a firewall change a one-evening job for most sites in Kolkata instead of a project.
A firewall that cannot be reached at nine at night is not really protecting anything. Our engineers configure and burn in each unit on our own bench before it ships, so what arrives on site already carries your rules and your addressing. If a unit fails inside warranty we arrange the replacement and put the saved configuration back on it. You get a named engineer to call, not a ticket number in a queue.
Patient Records, Imaging and Visitor Wi-Fi on One Line
A logistics operator running two warehouses outside Kamarhati lost its dispatch system for most of a day whenever roadworks cut the fibre. Both sites now bring two lines into one appliance, and the system moves to the backup line without anyone logging in to make it happen. The most recent cut was noticed only because somebody saw the alert email. Dispatch has not stopped since the changeover.
🛡️ NETWORK SECURITY WORK, DONE PROPERLY
Support You Can Reach After Installation
Putting a next-generation firewall into a working office in Kamarhati is mostly planning, not screwdriver work. We start by listing what actually runs on your network - Tally, the CCTV recorder, the biometric machine, the two broadband lines nobody documented - before a single rule gets written. Only then do we agree a cutover slot, usually after hours, with an agreed way back if something misbehaves.
Our engineers cover the following, across offices in and around Kolkata:
▪Out-of-Hours Switchover from Your Old Firewall
▪Firewall Supply, Setup and Commissioning
▪Infected Laptops Cut Off Automatically (Synchronized Security)
▪Unknown-Attachment Checks and Quarantine Rules
*Important: fees apply to survey visits, cutover nights and emergency call-outs. Nothing on this page forms part of a factory support entitlement.*
💡 Engineering Fact: An attachment nobody has seen before is opened first inside a throwaway computer in the cloud. If it starts encrypting files or hiding from the operating system, it is never delivered to your staff.

Below you will find sizing guidance alongside the technical ratings:
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.
🔹 SPEED
A second chip handles ordinary traffic while the main one runs the security checks, which is why browsing does not crawl once scanning is on (Xstream FastPath).
🔹 NOISE
No fan inside. It can live in a reception area or a director's cabin and nobody hears it.
🔹 SIZE
About as big as a thick hardback book, so it fits on a shelf or inside a small wall cabinet.
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.
🔹 LOAD
Antivirus, intrusion checks and encrypted-site scanning can all run together without the branch tunnels slowing to a crawl.
🔹 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.
🔹 POWER
Two power packs come fitted as standard, and a dead one slides out and gets replaced while the rest keeps running.
🔹 WHAT'S EXTRA
Rails, fibre modules and the right cables are quoted per site - we confirm cabinet depth before anything is dispatched.
🔹 VERY FAST PORTS
Twenty-five and forty-gigabit fibre sockets, so the firewall is never the narrow point between server rows.
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 IT IS NOT
This is not a standalone firewall. It leans on the main appliance, so budget for both together.
🔹 WHO CONTROLS IT
Every rule stays at head office. The branch cannot change a thing, which is usually the whole point.
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.
🔹 WHERE IT'S MANAGED FROM
The same cloud dashboard as the firewall, so one login covers both instead of two separate systems.
🔹 WHAT IT'S FOR
Turning one network point into eight, twenty-four or forty-eight, with a proper record of what is plugged where.
🔹 WHAT'S EXTRA
Check the total watts on offer before ordering. Thirty cameras on one switch will use up a small power budget quickly.
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.
🔹 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.
🔹 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 THE USER DOES
Signs in with the usual office email and password, plus a code on the phone as a second step.
🔹 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.
🔹 RANSOMWARE
It watches for a program that suddenly starts encrypting files, stops it, and puts the changed files back.
🔹 SERVERS
The Tally server, ERP box and file server get settings tuned so the month-end run does not slow to a crawl.
🔹 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.
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.
🔹 BUNDLES
One combined subscription covers most of the protection at a better rate than buying the modules one by one.
🔹 WHAT PEOPLE REGRET
Letting it run dry for a couple of months to save money, then paying for reinstatement plus the clean-up afterwards.
🔹 AUDITS
An auditor checking your security controls will ask for proof the subscription is live. A lapsed one is a finding.

🧾 Feature List and Technical Detail in and around Kamarhati
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.
Remote access is part of the base capability, not a separate box. Depending on model, the appliance carries anywhere from a few dozen to several hundred simultaneous encrypted connections, counting staff at home, branch tunnels and travelling users together. If you are planning for a work-from-home week, tell us the peak number and the sizing will allow for it.
🔹 Room temperature it tolerates0°C to 40°C (32°F to 104°F)
🔹 What's insideMulti-core processor plus a separate Xstream security chip (NPU)
🔹 Unknown attachmentsOpened in a cloud sandbox before they reach a user
🔌 Spare power supplyOptional on the smaller rack models, fitted as standard and hot-swappable on the larger ones
🔹 If the main unit failsStandby takes over - Active-Passive or Active-Active HA cluster
🔹 Where it's managed fromWeb browser, command line, or the Sophos Central cloud console
What Enterprise Grade Means on a Production Line
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).
New threats appear faster than anybody can keep up with by hand, so the web categories, application signatures and known-bad addresses refresh on their own through the day. A file nobody has a verdict on yet is examined in Sophos's cloud analysis service before it reaches the person waiting for it. Nothing on your side depends on somebody remembering to update anything.

EVERYDAY WINS IN ONE LIST
WHAT NEEDS SETTING UP FIRST - THE SHORT LIST
✓You can see which application is eating the bandwidth at 3pm and cap just that one, without blocking the whole internet.
—Rackmount units are audibly loud under load. Put one in an open office and somebody will complain by the second week.
✓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.
✓The steel case is shaped to pull air front to back, which is what keeps the unit alive in a warm, dusty cabinet.
—In-depth logging fills the internal disk if nobody sets rotation or ships the logs off the box.
✓Office WiFi points are managed from the same screen as the firewall, which saves buying a separate controller.
—Firmware updates drop sessions briefly. On a single unit that means a late-night window agreed with the people who actually work late.
✓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).
—VPN speed between branches is capped by the upload speed your ISP gives you. No firewall can invent bandwidth the line does not have.
💡 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.

Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Kamarhati
🛠️ Workflow Setup
Handover is a folder, not a handshake. Passwords, rule list, port labels, licence dates and the number to call. Two weeks later we read the logs again and quieten anything that is over-alerting.
⚠️ Pitfalls to Avoid
Switching off every alert because the first week was noisy leaves you with an expensive box that watches carefully and tells absolutely no one.
🔌 Guidelines & Sizing
Put the firewall on an online UPS rather than the ordinary backup kind. The changeover gap on a cheap unit is long enough to reboot the box, and a reboot at eleven in the morning is not a small event.
📈 Upgrade Triggers
Twenty people became sixty, the WiFi now has three extenders hanging off it, and nobody can say which device on the network is which.
📖 Honest Pros and Cons From the Bench around Kamarhati
Do not leave office computers pointing at whatever DNS the ISP handed out. Point them at your own server, have it forward through the firewall, and you can suddenly filter and log every area lookup - which is how you notice a machine quietly talking to something it should not. When ransomware is preparing itself, DNS is usually where it shows up first.
A plastic desktop security box is fine until the day it is not: no second power supply, no standby unit, no fibre port, and a fan that gives up in a warm room. The metal rack units are designed for continuous running.
Software firewalls installed on a Windows server share that server's fate. When it needs a reboot, fills its disk or catches something, your perimeter goes with it - a separate appliance simply keeps working.
💡 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.
🛠️ Fitting the Appliance into a Rack That Is Already Full near Kamarhati
Plant floors, clinics and open-plan offices each throw up a different mounting problem; here is how our teams handle the common ones across Kolkata.
✅ Configuration & Testing - How It Works in Kamarhati
🔹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.
🔹Clean fibre ends with an optical pen before seating them in SFP+ slots. Most links that flap every few minutes on dusty sites near Kamarhati are carrying a speck of dust, not a faulty module.
Frequently Asked Questions
Q. Can we block YouTube for some staff but not others?
Yes, because rules follow the person rather than the machine. The firewall reads your office login system, so it knows who is sitting there and applies their rules to whichever desk they use (Active Directory or SAML sign-on). Marketing keeps YouTube, the shop floor does not, and a shared computer behaves correctly for each person. You can also cap instead of block - give streaming a thin slice of bandwidth and protect the rest for work.
Q. Is one enough, or do we need two?
One is enough for most offices. Two is worth it when a few hours offline would genuinely cost money or safety - a production line, a hospital, a call centre, a trading desk. The second unit sits quiet and takes over inside a second when the first one fails, so nobody on a call notices anything (Active-Passive HA). It roughly doubles the hardware spend, so do the sum honestly: what does one lost day actually cost you?
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. 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. Will this slow down our internet?
In normal use you should not notice it at all. The appliance carries a second chip that handles routine traffic while the main chip does the security checks, so the scanning and the routing happen side by side rather than queueing (Xstream FastPath). Slowdowns creep in when a unit is undersized for the number of staff, or when every last rule is set to deep-scan everything. We size the box against your headcount and your line speed, and we tell you which settings cost speed before you switch them on.
💡 Engineering Fact: Branch tunnels send each other a small hello at regular intervals. When a branch link dies, that silence is noticed and the tunnel rebuilds itself, instead of sitting dead until someone at that branch phones to complain.
