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 Deployment, Migration and Handover throughout Kolkata
Every second monsoon the fibre to your branch goes down and the branch simply stops billing. Put a second, cheaper broadband line into the same SophosNext-Gen Firewall for Business Networks and it watches both, shifting traffic to the healthy one before staff notice anything (SD-WAN link steering). Voice and billing get the clean line; backups and updates take whatever is left. For a branch near Salkia that used to sit idle until the line came back, that is the difference between a lost day and a slow hour.
Your guest Wi-Fi password has been on a whiteboard for two years, and the camera recorder shares a network with the accounts computer. This appliance splits one flat office network into separate lanes - staff, guests, cameras, production machines - so trouble in one lane cannot wander into another (VLAN zone policies). Visitors still get internet; they simply cannot see your servers. It is the cheapest tidy-up available to most offices and it takes an afternoon.
⭐ Where Sophos Next-Gen Firewall for Business Networks Earns Its Keep around Salkia
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 Salkia.
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
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:
▪Firewall Supply, Setup and Commissioning
▪Branch-to-Branch and Work-from-Home VPN Setup
▪Unknown-Attachment Checks and Quarantine Rules
▪Separate Lanes for Guest WiFi, CCTV and Accounts (VLANs)
*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: 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.
⚡ SWITCHOVER AFTER HOURS

🛒 Pick the Right Variant Without Overspending for offices in Salkia
Compare ports, speed and licence options before you decide:
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.
🔹 GUEST WIFI
Visitors and staff run on different networks, so a guest laptop never sees the accounts machine (VLAN).
🔹 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.
🔹 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).
🔹 FITS
One rack unit high in a standard 19-inch cabinet, with cool air drawn in at the front and pushed out at the back.
🔹 HEAT
Front-to-back cooling copes with a warm server room, though we still insist on a working AC and a clean filter.
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.
🔹 POWER
Two power packs come fitted as standard, and a dead one slides out and gets replaced while the rest keeps running.
🔹 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.
🔹 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.
🔹 BACKUP LINE
A second connection, including a 4G or 5G dongle, can be attached where the local broadband is unreliable.
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.
🔹 LANES
Cameras, billing machines, guest WiFi and staff laptops stay apart on the same physical cabling (VLANs).
🔹 WHAT'S EXTRA
Check the total watts on offer before ordering. Thirty cameras on one switch will use up a small power budget quickly.
🔹 IF A PORT MISBEHAVES
You can spot the guilty port and shut it from the screen, instead of unplugging cables one at a time.
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.
🔹 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.
🔹 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.
🔹 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 IT NEEDS
A small agent on the laptop and the gateway running on your firewall or from the cloud console.
🔹 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).
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.
🔹 WHAT IT'S FOR
Guarding the laptops, desktops and servers themselves, rather than only the door they sit behind.
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.
🔹 AUDITS
An auditor checking your security controls will ask for proof the subscription is live. A lapsed one is a finding.
🔹 BUNDLES
One combined subscription covers most of the protection at a better rate than buying the modules one by one.
🔹 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.

🔍 Common Failures and How We Fix Them for offices in Salkia
Turn reporting on from day one, even if nobody reads it for months. A log is only ever valuable in hindsight - the week you need to answer when this started and who was on that machine, a log that began yesterday is worth nothing. I set a weekly summary for the owner and a monthly detail report for whoever handles IT in Salkia. It also turns out to be the easiest way to justify the renewal.
Every serious next-gen brand blocks much the same set of threats, so the choice usually turns on three practical things: the throughput figure with encrypted inspection switched on, how many sessions the model holds at your busiest hour, and whether you want depth at one large site or light boxes at many small ones. Ask each vendor for the inspected number rather than the headline one and the shortlist tends to write itself.
Buying separate boxes for web filtering, remote access and intrusion prevention leaves you with three renewal dates, three consoles and three vendors pointing at each other. One appliance with one policy list is easier to run and much easier to hand over.
💡 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.
⚙️ SYSTEM EVALUATION & CHECKLIST
Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Salkia
🛠️ 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.
🛠️ Power, UPS and Earthing - Don't Skip This
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.
🔧 Server Room Housekeeping - A Timeline around Salkia
🔹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 Salkia, 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.

BENEFITS YOU WILL NOTICE ON ONE PAGE
COMMON COMPLAINTS - WORTH READING FIRST
✓Selected rack models keep the wire connected even if the appliance loses power, so a production line does not halt (bypass ports).
—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).
—Traffic pushed through anonymising proxies or unmanaged tunnels sits outside these controls, so policy alone will not stop a determined employee.
✓Office WiFi points are managed from the same screen as the firewall, which saves buying a separate controller.
—Fibre ports ship empty. Transceivers or DAC cables are a separate buy, and the wrong part simply will not link up.
✓Nothing has to be installed on a personal laptop, which matters when the person using it is a contractor you will not see again after March (clientless HTML5 portal with MFA).
—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.
✓Threat lists refresh on their own through the day, so protection never depends on somebody remembering to update it.
—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: 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 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 Salkia, the figure that matters is not the headline number but the throughput with inspection running, and that is the one we quote.

Firmware Signing and Secure Boot: Sophos Standards
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. 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. What happens if it stops working on a Sunday?
Ring the support number and we start on it the same day, usually remotely, and for most faults we can talk someone through a temporary bypass so Monday morning is not a write-off. If the hardware itself has died, replacement runs through the manufacturer warranty, and the speed of that depends entirely on which support pack you bought - a next-business-day pack and a plain return-to-base pack are very different waits. We hold common spares on the shelf, but we will not pretend a unit can be at your gate within two hours. If a few hours offline is genuinely unaffordable, the honest answer is a standby unit, not a faster courier.
Q. How does it check encrypted sites without making browsing slow?
Nearly all web traffic is https today, so a firewall that cannot look inside encrypted sessions is blind to most of what arrives. Dedicated crypto hardware inside the appliance does the decryption maths, inspects the contents, and re-encrypts, instead of borrowing the main processor for the work (hardware-accelerated TLS 1.3 inspection). Day to day, browsing feels ordinary. Two caveats: a handful of banking and government sites have to be left out of inspection, and every office device needs the firewall's certificate installed or browsers will throw warnings.
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. What paperwork does this give us at audit time?
Logs and reports showing who went where, what was blocked, and when someone changed a rule - which is usually what an ISO, RBI or customer security audit is really asking to see. Reports can be scheduled and mailed to a named person every month, so nobody has to remember. Bear in mind that keeping logs for a long period needs storage, either on the appliance or on a central reporting service, and that is a decision better made before the auditor arrives than after. We set the reporting up during installation.
💡 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.
