A firewall with half its features switched off is not a firewall. That is what usually happens in practice: someone turns on virus scanning, the network slows to a crawl, and within a week the setting is quietly disabled again. The XGS boxes carry a separate chip for ordinary traffic, which is the whole reason the protection can stay on all the time. At Microtech Solutions we commission them with everything running, then show you the throughput figures so you know nothing was traded away.

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 Science City.
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.
⭐ Where Sophos Next-Gen Firewall for Business Networks Earns Its Keep around Science City
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.
Firewall pricing confuses people because the hardware and the subscriptions are two separate things. We put both on one page: what the box costs, which protection bundle your kind of office genuinely needs, what renews and on what date. If something in a bundle is of no practical use to you, we will say so rather than sell it. Nobody enjoys finding out an expired licence in the middle of an incident, least of all in a busy office near Science City.
A School Network That Survives Exam Week
A footwear chain with eleven counters across Kolkata kept losing card payments whenever the shop Wi-Fi filled up with customer phones. A firewall at each store now keeps the payment terminals on their own lane with priority on the line, and the guest network cannot see them at all. Queue times at the till stopped being an internet problem. Head office also gained one screen showing which store's connection is misbehaving today.
🛡️ FIELD EXPERIENCE AND ENGINEERING PRACTICE
Why We Write Everything Down
Putting a next-generation firewall into a working office in Science City 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:
▪Annual Maintenance Contracts and Response-Time Cover
▪Infected Laptops Cut Off Automatically (Synchronized Security)
▪Two or Three Internet Lines Used Together, Switching by Themselves (SD-WAN)
▪Emergency Hardware Replacement and Config Restore
*Please read: we are an independent service provider. Our engineering time is billable, and it is neither a substitute for nor connected to Sophos's own warranty helpdesk.*
💡 Engineering Fact: Two units can be paired so that if the working one dies, the spare picks the traffic up fast enough that a call in progress usually survives it. It manages that because it has been quietly kept up to date on every open connection all along.
⚡ SWITCHOVER AFTER HOURS
Replacing a firewall that is still carrying live traffic in Science City? We plan the cutover for after hours, leave the old unit racked until the morning passes quietly, and hand over the rollback steps in writing.
🛒 Product and Licence Line-Up for offices in Science City
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.
🔹 NOISE
No fan inside. It can live in a reception area or a director's cabin and nobody hears it.
🔹 PORTS
Six to eight network sockets, with a fibre slot on the bigger models for a leased line.
🔹 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).
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.
🔹 FIBRE PORTS
Ten-gigabit fibre sockets go straight into your core switch with no converter box in the middle (SFP+).
🔹 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.
🔹 POWER
Two power packs come fitted as standard, and a dead one slides out and gets replaced while the rest keeps running.
🔹 SIZE
Two rack units, considerably heavier, and it needs proper rails in a full-depth cabinet rather than a shelf.
🔹 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.
🔹 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.
🔹 HOW IT CONNECTS
An encrypted tunnel back to the main firewall makes the branch behave like another room at head office.
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 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.
🔹 IF A PORT MISBEHAVES
You can spot the guilty port and shut it from the screen, instead of unplugging cables one at a time.
🔹 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.
🔹 WHO IT SUITS
Schools with tablets, hotels, co-working floors, and warehouses running handheld barcode scanners.
🔹 WHERE IT'S MANAGED FROM
One cloud console shows every unit, who is connected and which one is the busiest.
🔹 COVERAGE
Plan by walls, not by wattage. A brick partition or a lift shaft eats more signal than most people expect.
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.
🔹 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.
🔹 WHAT IT NEEDS
A small agent on the laptop and the gateway running on your firewall or from the cloud console.
🔹 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.
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.
🔹 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.
🔹 WHO IT SUITS
Any office where users are local administrators, or where pen drives still move between machines daily.
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.
🔹 AUDITS
An auditor checking your security controls will ask for proof the subscription is live. A lapsed one is a finding.
🔹 WHAT PEOPLE REGRET
Letting it run dry for a couple of months to save money, then paying for reinstatement plus the clean-up afterwards.

🔍 Honest Pros and Cons From the Bench for offices in Science City
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: 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.

📈 What Happens When Everyone Logs In at Once for offices in Science City
Read the good and the awkward together before you shortlist a model.
EVERYDAY WINS ON ONE PAGE
WHAT NEEDS SETTING UP FIRST - WORTH READING FIRST
✓Office WiFi points are managed from the same screen as the firewall, which saves buying a separate controller.
—The sandbox, web filtering and threat feeds are subscription items. When the term ends those checks stop, and renewal is a real line in next year's budget.
✓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).
—Bypass ports exist only on certain rack models. If your line needs that behaviour, it has to be confirmed before the buy order, not after delivery.
✓Mail carrying an unknown attachment is held back while it is checked, and the person expecting it gets a note explaining the delay instead of silence (cloud sandbox quarantine).
—In-depth logging fills the internal disk if nobody sets rotation or ships the logs off the box.
✓Every branch firewall is configured and watched from one browser login, which starts to matter past the third site (Sophos Central).
—To read inside encrypted sites, a certificate has to be pushed to every company laptop first. Personal and unmanaged devices will keep throwing warnings until that is sorted.
✓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).
—Traffic pushed through anonymising proxies or unmanaged tunnels sits outside these controls, so policy alone will not stop a determined employee.
💡 Engineering Fact: During a call, the firewall holds a large file download back by a fraction of a second so the voice packets go first. That tiny delay is why the download still finishes and nobody sounds like a robot.

Everything below comes from actual site visits rather than from a manual, so treat it as the checklist your installer ought to be working through.
🔧 Installation & Setup - How It Works in Science City
🔹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 Science City, 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.
🔹Save yourself an argument with the routing table next year: put the LAN gateway address on a real physical port rather than inside a bridge group, because every VLAN you add later has to live with that decision.
📈 Feature List and Technical Detail across Kolkata
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.
Specification sheets are written for engineers, so here is the short version. The appliance runs two kinds of processing side by side: one part moves ordinary traffic at full speed, the other does the inspection work, which is why throughput holds up once features are switched on. For an office in Science City, the figure that matters is not the headline number but the throughput with inspection running, and that is the one we quote.
🏆 CORE PARAMETER🔹 What's insideMulti-core processor plus a separate Xstream security chip (NPU)
🔹 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
🔹 Where it's managed fromWeb browser, command line, or the Sophos Central cloud console
🔹 If the main unit failsStandby takes over - Active-Passive or Active-Active HA cluster
🔌 Spare power supplyOptional on the smaller rack models, fitted as standard and hot-swappable on the larger ones
🔹 Sizes you can buyFanless desktop, 1U rackmount, 2U rackmount
What Enterprise Grade Means on a Production Line
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).
Your unit will probably not live in a data centre. It may well live in a cupboard behind reception with the door shut, so the hardware assumes that: continuous-duty fans, power circuitry that tolerates a wobbly supply, and a steel case that bolts into a rack or sits on a shelf. On the rack models a second power supply makes a lost feed an annoyance rather than an outage.

🛠️ Workflow Setup
On the day, the box goes into the rack, power comes off two circuits wherever the room allows, and the internet cable moves across from the old router. The old one stays connected and ready to go back.
⚠️ Pitfalls to Avoid
Rolling out encrypted-traffic checking before the certificate has reached every computer is the fastest possible way to have the whole office declare the new firewall broken.
🔌 Guidelines & Sizing
Label every cable at both ends before the cabinet door closes. The half hour you spend now is the half hour nobody spends at midnight guessing which lead goes where.
📈 Upgrade Triggers
The firewall you have stopped getting updates a couple of years ago and the manufacturer's site now lists it as end-of-life.
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 our staff still work from home?
Yes, and for many buyers that is half the reason for buying it. Staff install a small app, sign in with their office username plus a second factor, and then work as though they were at their desk (IPsec or SSL VPN). For anyone who cannot install software there is a browser-based route into a remote desktop or a shared folder. One limit worth naming: home broadband quality still sets the speed, and no firewall can make a weak line at somebody's house behave.
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. 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. 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.
💡 Engineering Fact: Some models carry a relay that clicks the incoming and outgoing ports together the instant power is lost. Traffic keeps flowing, unprotected but flowing, which buys you the hours until someone reaches the site.
