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 throughout 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.
⭐ Where Sophos Next-Gen Firewall for Business Networks Earns Its Keep around Joygachi
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 Joygachi.
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
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 Joygachi 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:
▪Unknown-Attachment Checks and Quarantine Rules
▪Emergency Hardware Replacement and Config Restore
▪Quarterly Rule Review and Clean-Up of Dead Policies
▪Encrypted Website Scanning and Certificate Rollout
*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 Joygachi? 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.
🛒 Complete List of What We Supply for offices in Joygachi
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.
🔹 SIZE
About as big as a thick hardback book, so it fits on a shelf or inside a small wall cabinet.
🔹 GUEST WIFI
Visitors and staff run on different networks, so a guest laptop never sees the accounts machine (VLAN).
🔹 WHAT'S EXTRA
A bracket kit is sold separately if you later want it screwed into a rack instead of standing on a table.
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.
🔹 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.
🔹 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.
🔹 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.
🔹 BUSY NETWORKS
Sized for the case where thousands of people, cameras and machines all hold connections open at the same moment.
🔹 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.
🔹 BUILD
Metal body, low power draw, no fan, so it survives a dusty stores room far better than a plastic consumer router.
🔹 WHAT STAFF SEE
Tally, the shared folder and the head office printer open exactly the way they do at the main location.
🔹 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.
🔹 IF A PORT MISBEHAVES
You can spot the guilty port and shut it from the screen, instead of unplugging cables one at a time.
🔹 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.
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.
🔹 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.
🔹 WALKING AROUND
Handover between units is quick enough that a call on WiFi survives a walk from the cabin to the shop floor.
🔹 WHERE IT'S MANAGED FROM
One cloud console shows every unit, who is connected and which one is the busiest.
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'S EXTRA
Licensed by number of users, so a five-person accounts team is paid for as five, not as the whole staff.
🔹 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'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.
🔹 SERVERS
The Tally server, ERP box and file server get settings tuned so the month-end run does not slow to a crawl.
🔹 REPORTING
One list of every machine, whether its updates are current, and which computer is the repeat offender.
🔹 WHAT'S EXTRA
Mail and mobile device protection are separate add-ons and are worth pricing at the same time.
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.
🔹 MULTI-YEAR TERMS
A three-year term fixes the cost and removes two rounds of buy orders, approvals and chasing.
🔹 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.

🔧 Server Room Housekeeping - What We Do in and around Joygachi
🔹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 Joygachi, 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.
📈 Licence Tiers and What Each One Covers 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 Joygachi, the figure that matters is not the headline number but the throughput with inspection running, and that is the one we quote.
🏆 CORE PARAMETER🔹 Unknown attachmentsOpened in a cloud sandbox before they reach a user
🔌 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
🔹 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)
🔹 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
🔹 Where it's managed fromWeb browser, command line, or the Sophos Central cloud console
Built to Run Non-Stop, Not Nine to Five
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.
🔍 Practical Findings After a Year in Service for offices in Joygachi
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: 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.

WHAT OWNERS LIKE ON ONE PAGE
COMPROMISES TO ACCEPT - WORTH READING FIRST
✓A cheap second broadband connection stops being a spare cable in a drawer and becomes real insurance, because the box moves traffic onto it without anyone logging in (SD-WAN).
—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.
✓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).
—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.
✓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).
—Encrypted scanning costs throughput. Size the box for the traffic you intend to inspect, not the headline number on the brochure, or users will feel it.
✓Threat lists refresh on their own through the day, so protection never depends on somebody remembering to update it.
—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.
✓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 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.
💡 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.

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.
Q. Why should Microtech Solutions install it instead of our own IT person?
You can absolutely do it yourself, and a capable in-house IT person can manage an entry-level unit without drama. What tends to go wrong on self-installs is rule ordering, the certificate never reaching every PC, a standby pair that was never actually tested, and a segmentation plan nobody drew. Those show up months later as sluggish browsing, or as an infection that spread further than it should have. We size the unit, build the rules alongside you, test the failover, hand over the documentation - and we are the number you ring at 9pm anywhere in Kolkata.
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. 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.
💡 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.
