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.
✅ From Quotation to Go-Live with Sophos anywhere in Kolkata
An unsupported firewall is a locked door whose key everyone has already copied - from the outside it still looks fine. Moving to a current SophosNext-Gen Firewall for Business Networks puts you back on supported firmware, live protection updates and a warranty you can actually claim. We copy your existing rules across, remove the dead ones, and do the switch in the evening so the morning shift finds nothing changed. Offices across Kolkata usually get a rule-by-rule handover document before the old unit leaves the rack.
When two hundred students discover the same streaming site, the exam portal is the first thing to suffer. Application-aware rules let you cap entertainment traffic and hold back a fixed slice of the line for the things that matter - exams, fee payments, the office. Staff and student networks stay apart, each with its own filtering profile. Schools and colleges in Kolkata run all of this on a single SophosNext-Gen Firewall for Business Networks without needing a full-time network person.
🧠 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 Halisahar 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 Halisahar 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
Sizing is where most firewall purchases go wrong. We ask how many people are online at once, how much of the traffic is encrypted, whether you intend to inspect it, and whether branches will be joined in - then quote the model that survives that load, even when a smaller one looks better on price. If the honest answer is that you do not need the bigger box, we say so.
The work we take on, listed plainly - all of it chargeable and quoted before anyone starts:
▪Separate Lanes for Guest WiFi, CCTV and Accounts (VLANs)
▪Out-of-Hours Switchover from Your Old Firewall
▪Firewall Supply, Setup and Commissioning
▪Infected Laptops Cut Off Automatically (Synchronized Security)
*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: 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.

🏷️ Ranges Sorted by Office Size for offices in Halisahar
Scan the hardware details, then tell us your user count and line speed:
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.
🔹 WHAT'S EXTRA
A bracket kit is sold separately if you later want it screwed into a rack instead of standing on a table.
🔹 POWER
Draws little enough that a small office UPS carries it and the modem straight through a cut.
🔹 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.
🔹 HEAT
Front-to-back cooling copes with a warm server room, though we still insist on a working AC and a clean filter.
🔹 LOAD
Antivirus, intrusion checks and encrypted-site scanning can all run together without the branch tunnels slowing to a crawl.
🔹 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).
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.
🔹 SIZE
Two rack units, considerably heavier, and it needs proper rails in a full-depth cabinet rather than a shelf.
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'S FOR
Very small sites - a warehouse office, a godown, a two-person branch - that still need to be on the head office network.
🔹 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.
🔹 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).
🔹 WHERE IT'S MANAGED FROM
The same cloud dashboard as the firewall, so one login covers both instead of two separate systems.
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.
🔹 COVERAGE
Plan by walls, not by wattage. A brick partition or a lift shaft eats more signal than most people expect.
🔹 WALKING AROUND
Handover between units is quick enough that a call on WiFi survives a walk from the cabin to the shop floor.
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.
🔹 CONTRACTORS
A vendor can be given one server for a fixed number of days, after which the access simply stops.
🔹 RECORDS
Each session is logged by person and by application, which is normally the exact evidence an audit wants.
🔹 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.
🔹 WHAT IT REPLACES
The free antivirus that quietly expired two years ago and the paid one nobody renewed after the IT person left.
🔹 SERVERS
The Tally server, ERP box and file server get settings tuned so the month-end run does not slow to a crawl.
🔹 RANSOMWARE
It watches for a program that suddenly starts encrypting files, stops it, and puts the changed files back.
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.
🔹 WHAT IT'S FOR
Keeping virus updates, web filtering, sandbox checks and vendor support current on a firewall you already own.
🔹 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.
🔹 HOW WE HANDLE IT
Microtech Solutions flags the expiry date well in advance, so the paperwork is not being run around on the last afternoon.

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.
🔧 User Training & Handover - What We Do in and around Halisahar
🔹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 Halisahar, 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.

WHAT OWNERS LIKE - FOR BUYERS
COMPROMISES TO ACCEPT - A QUICK LIST
✓Selected rack models keep the wire connected even if the appliance loses power, so a production line does not halt (bypass ports).
—Central cloud reporting needs a working outbound connection. At a site with a flaky line, expect gaps in the dashboards.
✓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.
✓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).
—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.
✓An ageing core switch and a new fibre run can both plug into the same box, so nobody is forced into replacing the switch in the same month (port mix varies by model).
—Rackmount units are audibly loud under load. Put one in an open office and somebody will complain by the second week.
✓The steel case is shaped to pull air front to back, which is what keeps the unit alive in a warm, dusty cabinet.
—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.
💡 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.

🛠️ 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.
📋 Key Figures Every Buyer Should Check 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 Halisahar, 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
🔹 If a laptop gets infectedFirewall isolates it on its own - Synchronized Security heartbeat
💾 Log storage on boardGood for large-scale setups SSD for local reporting and audit trails
🔹 If the main unit failsStandby takes over - Active-Passive or Active-Active HA cluster
🔹 Sockets on the boxgigabit copper as standard, with 2.5-gigabit copper and 10-gigabit fibre on the models that offer them - we confirm the port list against the model you order
🔹 Room temperature it tolerates0°C to 40°C (32°F to 104°F)
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.

💡 Practical Findings After a Year in Service after years of site visits
Pushing the inspection certificate to company laptops is straightforward; personal phones are where it gets untidy. My advice is to keep personal and guest devices on a network where encrypted inspection is off but category filtering is on. You get most of the benefit and none of the certificate-warning support calls. Save full inspection for machines the company actually owns.
An internet provider's optional security add-on filters at their end, on their terms, with no report you can put in front of an auditor and little control over what is allowed for whom. Owning the box means owning the rules and the logs.
Compared with leaving remote staff on shared passwords and an open remote-desktop port, giving each person an encrypted tunnel with a second login check removes the single most common way small companies get broken into.
💡 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.
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 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. 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.
Q. How long does installation take, and will the office be shut?
A single-site install is generally a one-day job, and the only real interruption is the ten to twenty minutes when your internet connection moves across to the new box. We do that changeover early morning, after hours, or on a Saturday - whichever hurts least. Sites with several floors, more than one internet line, or a big pile of existing rules take two or three days, because rules have to be rebuilt and tested rather than copied over blindly. The cutover window is agreed with you in writing before anyone turns up in Halisahar.
💡 Engineering Fact: On the larger models, two power packs share the load, and if one input dies the other takes the whole thing on instantly. In practice that input usually dies because of a tripped circuit or a wrongly pulled plug.
