Monsoon week is when the weak links show themselves. One broadband line drops, and half the office stops working until somebody notices. Plug two or three connections into the same firewall and the traffic simply moves to whichever line is alive, quickly enough that a video call survives the switch. I set the rules so billing and phone calls get first claim on the bandwidth, and general browsing takes what is left over.
🤝 From Quotation to Go-Live with Sophos around Itna Colony
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.
✅ Benefits Your Accounts Team Will Notice throughout Kolkata
You already own a Windows login system, a set of switches and possibly a Wi-Fi controller you would rather not replace. This gateway reads your existing office logins, so rules follow the person rather than whichever machine they sat at, and it drops into your current switch layout without re-cabling the floor. Nothing else has to be ripped out on day one. That is what makes a firewall change a one-evening job for most sites in Kolkata instead of a project.
A firewall that cannot be reached at nine at night is not really protecting anything. Our engineers configure and burn in each unit on our own bench before it ships, so what arrives on site already carries your rules and your addressing. If a unit fails inside warranty we arrange the replacement and put the saved configuration back on it. You get a named engineer to call, not a ticket number in a queue.
Patient Records, Imaging and Visitor Wi-Fi on One Line
A logistics operator running two warehouses outside Itna Colony lost its dispatch system for most of a day whenever roadworks cut the fibre. Both sites now bring two lines into one appliance, and the system moves to the backup line without anyone logging in to make it happen. The most recent cut was noticed only because somebody saw the alert email. Dispatch has not stopped since the changeover.
🛡️ NETWORK SECURITY WORK, DONE PROPERLY
Support You Can Reach After Installation
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:
▪Annual Maintenance Contracts and Response-Time Cover
▪Encrypted Website Scanning and Certificate Rollout
▪Out-of-Hours Switchover from Your Old Firewall
▪Fibre Links Between Buildings, Fitted and Terminated (10GbE Transceivers)
*Important: fees apply to survey visits, cutover nights and emergency call-outs. Nothing on this page forms part of a factory support entitlement.*
💡 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.

📁 Pick the Right Variant Without Overspending for first-time buyers
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.
🔹 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).
🔹 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.
🔹 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).
🔹 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.
🔹 POWER
Two power packs come fitted as standard, and a dead one slides out and gets replaced while the rest keeps running.
🔹 IF IT FAILS
Runs as a pair, and some sites run both units live so neither one sits idle (Active-Active clustering).
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.
🔹 WHAT IT IS NOT
This is not a standalone firewall. It leans on the main appliance, so budget for both together.
🔹 WHO CONTROLS IT
Every rule stays at head office. The branch cannot change a thing, which is usually the whole point.
🔹 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.
🔹 LONG RUNS
Fibre uplinks reach an upper floor or a second building without the speed loss a long copper run brings.
🔹 IF A PORT MISBEHAVES
You can spot the guilty port and shut it from the screen, instead of unplugging cables one at a time.
🔹 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.
🔹 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.
🔹 WHAT IT'S FOR
WiFi that holds up when twenty phones and laptops crowd into one meeting room.
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.
🔹 IF A LAPTOP IS LOST
Access is cut from the dashboard in a minute. Nobody has to change the VPN password for the whole company.
🔹 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.
🔹 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.
🔹 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.
🔹 WHAT IT REPLACES
The free antivirus that quietly expired two years ago and the paid one nobody renewed after the IT person left.
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.
🔹 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.

🛠️ Fitting the Appliance into a Rack That Is Already Full near Itna Colony
Spend ten extra minutes on mounting, airflow and labelling and you buy years of not having to think about the appliance at all.
⚙️ Power and Backup - What We Do in and around Itna Colony
🔹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.
🔹Give the HA pair its own cable. Run the heartbeat link directly between the two appliances on a dedicated port, never through a switch that somebody might reboot.
🔹Schedule the configuration backup on day one and send an encrypted copy off the site - the day you need that file is the day the box is dead.
📖 Practical Findings After a Year in Service around Itna Colony
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: 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
Then the checks: browsing, email, Tally, the card machine, the CCTV app on the owner's phone. We do not pack up until somebody from your side has confirmed each one works.
⚠️ Pitfalls to Avoid
Putting your busiest internal rule at the bottom of a long list costs speed for no reason at all, because the box reads from the top down every single time.
🔌 Guidelines & Sizing
Buy through a proper distribution channel and keep the invoice with the serial number on it. Both the warranty claim and the licence renewal start from that piece of paper, and grey-market units fail that test.
📈 Upgrade Triggers
Video calls break up whenever the sales team pulls a report, and each department is quite certain the other one is at fault.

WHAT OWNERS LIKE IN ONE LIST
COMPROMISES TO ACCEPT - THE SHORT LIST
✓Every branch firewall is configured and watched from one browser login, which starts to matter past the third site (Sophos Central).
—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.
✓You can see which application is eating the bandwidth at 3pm and cap just that one, without blocking the whole internet.
—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.
✓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).
—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.
✓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).
—Rackmount units are audibly loud under load. Put one in an open office and somebody will complain by the second week.
✓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).
—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: 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.

🧾 How Much It Handles Before It Slows Down in and around Itna Colony
Port layout decides how the box fits your building. Models arrive with ordinary gigabit copper ports for desks and switches, faster multi-gigabit ports for busy uplinks, and fibre slots where the cable run is long or the core switch is 10G. A leased line handed off on fibre and a broadband line on copper can end on the same unit without an extra media converter.
Rack models take two power supplies and can be paired with a second appliance, so neither a failed power feed nor a failed unit has to stop the office. Failover carries the live sessions across, which is the difference between a blip and a room full of dropped calls. Desktop models trade that redundancy for size and price, and for a single office in Kolkata that is usually the right trade.

One screen covers the rules, the address translation, the routing, what gets scanned and what gets reported, instead of five consoles that disagree with each other. Whoever inherits your network can read a single line per rule and see who it applies to, what it allows and what is being checked (one policy list).
If a computer in your office starts behaving like an infected one, you should not have to wait for somebody to raise a ticket. The protection software on the machine and the gateway talk to each other continuously, so an unhealthy machine is cut back within seconds and the alert names both the machine and the person using it (Synchronized Security).

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. 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. 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. 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. 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.
💡 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.
