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 Supply and Aftercare for Business Buyers at multi-branch offices
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 Chandra Pally.
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.
🔑 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 Chandra Pally 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 Chandra Pally buy the protection once and it stays switched on.
Export Houses and the Fake-Invoice Email Problem
A 60-machine garment unit near Chandra Pally 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 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.

📚 Pick the Right Variant Without Overspending for offices in Chandra Pally
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.
🔹 GUEST WIFI
Visitors and staff run on different networks, so a guest laptop never sees the accounts machine (VLAN).
🔹 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.
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).
🔹 LOAD
Antivirus, intrusion checks and encrypted-site scanning can all run together without the branch tunnels slowing to a crawl.
🔹 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.
🔹 IF IT FAILS
Runs as a pair, and some sites run both units live so neither one sits idle (Active-Active clustering).
🔹 VERY FAST PORTS
Twenty-five and forty-gigabit fibre sockets, so the firewall is never the narrow point between server rows.
🔹 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.
🔹 HOW IT CONNECTS
An encrypted tunnel back to the main firewall makes the branch behave like another room at head office.
🔹 IF IT FAILS
Swap the unit. The replacement pulls the same configuration down on its own, so there is nothing to set up again.
🔹 WHAT IT IS NOT
This is not a standalone firewall. It leans on the main appliance, so budget for both together.
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.
🔹 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).
🔹 LANES
Cameras, billing machines, guest WiFi and staff laptops stay apart on the same physical cabling (VLANs).
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.
🔹 WHAT PEOPLE GET WRONG
Buying two very powerful units instead of five ordinary ones. Spread beats strength almost every time.
🔹 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.
🔹 WHO IT SUITS
CA firms in filing season, sales teams, and any business whose auditor asks who opened what and when.
🔹 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 NEEDS
A small agent on the laptop and the gateway running on your firewall or from the cloud console.
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.
🔹 SERVERS
The Tally server, ERP box and file server get settings tuned so the month-end run does not slow to a crawl.
🔹 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 IT LAPSES
The box keeps passing traffic and the lights stay green, but new threats stop being recognised. That gap is where the trouble walks in.
🔹 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 IT'S FOR
Keeping virus updates, web filtering, sandbox checks and vendor support current on a firewall you already own.

🔧 Site Survey & Planning - How It Works in Chandra Pally
🔹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 Chandra Pally, 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.

EVERYDAY WINS - IN PLAIN WORDS
WHAT NEEDS SETTING UP FIRST SPELLED OUT UPFRONT
✓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).
—Automatic laptop isolation only works where the matching security agent is installed. Machines without it stay invisible to the firewall.
✓"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).
—Desktop models run on an external adapter with no second supply, so a failed adapter takes the office offline until a replacement reaches you.
✓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.
✓The second unit costs money and does nothing on most days, which is rather the point - it earns its keep on the one afternoon the first one dies (HA cluster).
—Traffic pushed through anonymising proxies or unmanaged tunnels sits outside these controls, so policy alone will not stop a determined employee.
✓Two power supplies mean a dead PSU is a spare-part job on Monday rather than an office shutdown on Friday (hot-swap redundant PSU).
—Without a UPS, every power cut becomes an unplanned reboot. Repeat that through a monsoon week and you are risking the hardware, not just the uptime.
💡 Engineering Fact: Hosting your own website or mail server means the world can knock on your door. The firewall can stand in front of it, reading each request and turning away the standard tricks attackers try first.

Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Chandra Pally
🛠️ 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.
🗒️ Honest Pros and Cons From the Bench for demanding workloads
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: 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.
🧮 How Much It Handles Before It Slows Down for larger offices
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 Chandra Pally, the figure that matters is not the headline number but the throughput with inspection running, and that is the one we quote.
🏆 CORE PARAMETER🔹 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
🔹 What's insideMulti-core processor plus a separate Xstream security chip (NPU)
🔌 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
💾 Log storage on boardGood for large-scale setups SSD for local reporting and audit trails
🔹 Joining your branchesSite-to-site IPsec, SSL VPN and plug-in RED devices
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.
✉️ SUPPORT DESK
Coordinate custom hardware configurations, AMC maintenance contracts, and site engineering visits directly with authorized integration desks.
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. 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. What does it cost to renew, and can the price go up later?
Renewal is priced by model and by the bundle you are on, so it moves if you change hardware or add modules. Vendor list prices are revised from time to time and we do not control that, so nobody should promise you a number frozen for life. What we can do is quote a multi-year renewal at the time of buy, which fixes the rate for that stretch. We also send the renewal quote well before expiry rather than the week after it lapses.
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.
💡 Engineering Fact: Log writing happens off to one side rather than in the middle of the traffic path. That is deliberate: recording what happened should never be the reason a packet takes longer to get through.
