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.
✅ Sophos Next-Gen Firewall for Business Networks Supply, Setup and Support anywhere in Kolkata
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.
Buying a firewall two sizes too big is expensive; buying one size too small is worse, because features get switched off one by one until it is just a router. We size the SophosNext-Gen Firewall for Business Networks against your actual staff count, your internet speed and the branches you plan to add. The range runs from a small desktop unit for one office to rack appliances with fibre ports for a head office. Tell us where you expect to be in three years and the quote for your site in Kolkata will be built for that, not for today.
🧠 What Changes in the First Month with a growing team
Owners rarely want to read firewall logs. They want three answers: is anything getting in, who is eating the internet line, and are we exposed anywhere obvious. Scheduled reports arrive by email in plain tables a manager can read without a translator, and the technical detail stays underneath for whoever needs it. When an insurer or a customer's compliance team asks about your controls, you have something real to send.
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 Serampore usually look one step ahead. When you do outgrow it, the configuration exports into a larger model rather than being retyped.
Retail Counters, Card Machines and a Line That Keeps Choking
A trading house near Serampore could never close month-end billing on time, partly because the accounts server was reachable from every machine in the building, including two riddled with adware. We fenced that server behind its own rules, tied access to office logins rather than to machines, and put web filtering in front of the general staff network. The month-end run finished on schedule for the first time in over a year. Two infected desktops turned up in the first week's report and were cleaned the same day.
🛡️ TESTING, CUTOVER AND ROLLBACK DISCIPLINE
How We Size, Quote, and Sometimes Say No
Every install ends with a written handover: the rule list, the VLAN plan, admin credentials passed on securely, and a one-page sheet covering what to do if. Offices near Serampore often have three people who each know a piece of the network and nobody who knows all of it. That document exists so the network does not turn into a problem the day someone resigns.
A short list of what we are usually called in for:
▪Fibre Links Between Buildings, Fitted and Terminated (10GbE Transceivers)
▪Infected Laptops Cut Off Automatically (Synchronized Security)
▪Out-of-Hours Switchover from Your Old Firewall
▪Emergency Hardware Replacement and Config Restore
*Notice: rates for on-site engineering, cabling and rule audits are shared before work starts. We do not act as, and are not an extension of, the manufacturer's support desk.*
💡 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.

🏷️ Complete List of What We Supply for offices in Serampore
What comes in the box, what costs extra, and what we add on site:
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).
🔹 WHAT'S EXTRA
A bracket kit is sold separately if you later want it screwed into a rack instead of standing on a table.
🔹 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.
🔹 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).
🔹 HEAT
Front-to-back cooling copes with a warm server room, though we still insist on a working AC and a clean filter.
🔹 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.
🔹 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.
🔹 WHO IT SUITS
Data centres, large campuses and companies holding tens of thousands of live connections at peak hour.
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.
🔹 HOW IT CONNECTS
An encrypted tunnel back to the main firewall makes the branch behave like another room at head office.
🔹 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.
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.
🔹 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.
🔹 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.
🔹 WHO IT SUITS
CA firms in filing season, sales teams, and any business whose auditor asks who opened what and when.
🔹 HOW IT DIFFERS FROM A VPN
An old-style VPN puts the laptop inside everything. This opens only the application that person is allowed to touch (ZTNA).
🔹 RECORDS
Each session is logged by person and by application, which is normally the exact evidence an audit wants.
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.
🔹 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.
🔹 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.
🔹 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
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.

CLEAR ADVANTAGES - FOR BUYERS
COSTS BEYOND THE QUOTE - A QUICK LIST
✓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).
—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.
✓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).
—Central cloud reporting needs a working outbound connection. At a site with a flaky line, expect gaps in the dashboards.
✓You can see which application is eating the bandwidth at 3pm and cap just that one, without blocking the whole internet.
—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.
✓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).
—True redundancy means buying two identical appliances. One box with a spare in the cupboard is not the same thing, and the second unit costs what the first one did.
✓Audit questions get answered with readable summaries of who went where, not a pile of raw log files.
—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: Files arrive split into pieces that often turn up out of order. The firewall reassembles them in memory before scanning, because half a virus in one packet and half in another would otherwise sail past untouched.

📋 Licence Tiers and What Each One Covers for small teams
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 Serampore, the figure that matters is not the headline number but the throughput with inspection running, and that is the one we quote.

How Sophos Actually Builds These Units
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.

🛠️ Sophos Gateway Installation Checklist for Site Engineers in Kolkata
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.
🔧 Network Setup & Cabling - The Plan for small and mid-sized teams
🔹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 Serampore, 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.
💡 Engineer Notes From Real Installations after years of site visits
Run the HA heartbeat straight between the two appliances. I have seen split-brain clusters caused by nothing more than an intermediate switch rebooting during a power event, after which both units believe they are in charge. A one-metre direct cable removes that entire class of problem. It is the cheapest reliability decision on the whole installation.
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.
Cloud-only filtering protects users while they are online through that service, but traffic between machines inside your own office never passes through it - and internal spread is exactly how ransomware travels once it is in.
💡 Engineering Fact: Every minute or so the box quietly tests each internet line by pinging a known point and timing the reply. When one line starts dropping packets, calls shift to the other before anybody in the office complains.
Frequently Asked Questions
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. 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. 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. 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. 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: 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.
