A trading firm called us because their accounts staff could not open the bank portal while the design team was uploading artwork. One internet line, no priority rules, everyone fighting over the same pipe. We put in a Sophos Next-Gen Firewall for Business Networks, gave banking and Tally traffic first claim on the bandwidth, and pushed the backup uploads to run after closing time. Same connection, same monthly bill, and the complaints stopped that week.
🤝 Local Engineers for Sophos Next-Gen Firewall for Business Networks around Dum Dum Park
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.
Half your team now works from home two days a week, and remote access currently means a shared password and some optimism. The SophosNext-Gen Firewall for Business Networks gives every person an encrypted tunnel of their own with a second login check on top, so a leaked password by itself opens nothing (SSL VPN with multi-factor login). A contractor can be given browser-only access to one application and nothing else. When somebody resigns, one click ends their access everywhere, which matters to any growing firm in Dum Dum Park.
✅ 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 Dum Dum Park 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
Rules are tested before they go live, not after. Where the site allows it we run the new policy alongside the old gateway, watch what breaks inside a controlled window, and keep the previous configuration exported so a rollback takes minutes. For manufacturing units around Dum Dum Park, where a stopped line costs real money, that rehearsal is not optional.
Typical assignments, from a first install to a 2am hardware swap:
▪Branch-to-Branch and Work-from-Home VPN Setup
▪Firewall Supply, Setup and Commissioning
▪Annual Maintenance Contracts and Response-Time Cover
▪Infected Laptops Cut Off Automatically (Synchronized Security)
*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: Fibre between two buildings works by shining a laser down glass thinner than a hair. The common short-range module reaches about 300 metres, and picking the wrong one for a longer run is the cheapest mistake in networking.
🔍 YEARLY SUPPORT & SPARES
Who do you call at nine at night when the gateway stops passing traffic? Ask about yearly support with a defined response time, firmware patching and a replacement unit held ready for sites across Kolkata.
Every model, its port layout and its rack requirement, listed together:
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).
🔹 POWER
Draws little enough that a small office UPS carries it and the modem straight through a cut.
🔹 NOISE
No fan inside. It can live in a reception area or a director's cabin and nobody hears it.
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.
🔹 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.
🔹 IF THE POWER GOES
Some models carry bypass sockets that physically join the two sides on power loss, keeping the line alive until you get there.
🔹 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.
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.
🔹 IF IT FAILS
Swap the unit. The replacement pulls the same configuration down on its own, so there is nothing to set up again.
🔹 BUILD
Metal body, low power draw, no fan, so it survives a dusty stores room far better than a plastic consumer router.
🔹 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.
🔹 WHAT'S EXTRA
Check the total watts on offer before ordering. Thirty cameras on one switch will use up a small power budget quickly.
🔹 LONG RUNS
Fibre uplinks reach an upper floor or a second building without the speed loss a long copper run brings.
🔹 WHAT IT'S FOR
Turning one network point into eight, twenty-four or forty-eight, with a proper record of what is plugged where.
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.
🔹 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.
🔹 WHAT IT NEEDS
A small agent on the laptop and the gateway running on your firewall or from the cloud console.
🔹 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.
🔹 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.
🔹 RANSOMWARE
It watches for a program that suddenly starts encrypting files, stops it, and puts the changed files back.
🔹 WHAT'S EXTRA
Mail and mobile device protection are separate add-ons and are worth pricing at the same time.
🔹 SERVERS
The Tally server, ERP box and file server get settings tuned so the month-end run does not slow to a crawl.
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.
🔹 MULTI-YEAR TERMS
A three-year term fixes the cost and removes two rounds of buy orders, approvals and chasing.
🔹 WHAT IT'S FOR
Keeping virus updates, web filtering, sandbox checks and vendor support current on a firewall you already own.
🔹 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.

🛠️ Fitting the Appliance into a Rack That Is Already Full near Dum Dum Park
Before anybody unwraps the appliance, walk the room once with this list and confirm that power, earth and rack space are genuinely ready.
📌 Data Migration & Cutover - A Walkthrough across Kolkata
🔹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.
🔹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.
📖 Where the Datasheet and Reality Differ around Dum Dum Park
Before you touch a working firewall, export the configuration and write the rules down in ordinary language. I have walked into offices where the only person who understood the rule set left two years ago and every change since has been made by guessing. A one-page document naming each rule and why it exists is worth more than most support contracts. Keep it with the backup file, stored somewhere off the site.
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.
The router your internet provider supplied is built to give you a connection, not to inspect what travels over it. It will not open an encrypted site, cannot tell you which machine is infected, and has no way to join your branches together.
💡 Engineering Fact: Files arrive split into pieces that often turn up out of order. The firewall reassembles them in memory before scanning, because half a virus in one packet and half in another would otherwise sail past untouched.
🧾 What the Numbers Mean for Your Office in and around Dum Dum Park
Remote access is part of the base capability, not a separate box. Depending on model, the appliance carries anywhere from a few dozen to several hundred simultaneous encrypted connections, counting staff at home, branch tunnels and travelling users together. If you are planning for a work-from-home week, tell us the peak number and the sizing will allow for it.
Day-to-day management is a browser page, and the same page exists in the cloud for anyone running more than one site. Reports can be scheduled by email - heaviest users, blocked threats, which application is eating the line. Configuration backups run automatically and can be sent off-site, which is exactly what you will want on the day a unit has to be changed in Kolkata.

Sophos Thermal Design and Internal Board Layout
New threats appear faster than anybody can keep up with by hand, so the web categories, application signatures and known-bad addresses refresh on their own through the day. A file nobody has a verdict on yet is examined in Sophos's cloud analysis service before it reaches the person waiting for it. Nothing on your side depends on somebody remembering to update anything.
Working from home is treated as normal here rather than something bolted on later. Your staff get an encrypted tunnel of their own, or browser-only access to a single application, with a second check at login - so the same rules apply whether somebody is at a desk or at a kitchen table (multi-factor remote access).

PRACTICAL GAINS IN ONE LIST
PREPARATION YOU WILL NEED - THE SHORT LIST
✓The fake invoice from a supplier's hijacked mail account arrives over https, and a gateway that cannot open encrypted pages hands it straight to your accounts desk - this one opens it (TLS 1.3 inspection).
—VPN speed between branches is capped by the upload speed your ISP gives you. No firewall can invent bandwidth the line does not have.
✓Threat lists refresh on their own through the day, so protection never depends on somebody remembering to update it.
—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.
—Desktop models run on an external adapter with no second supply, so a failed adapter takes the office offline until a replacement reaches you.
✓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).
—Automatic laptop isolation only works where the matching security agent is installed. Machines without it stay invisible to the firewall.
✓Office WiFi points are managed from the same screen as the firewall, which saves buying a separate controller.
—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.
💡 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.

🛠️ Workflow Setup
Site survey first, an hour or two at most. We count users and devices, look at where your internet lands, and check the cabinet for space and power. Nothing on your network changes that day.
⚠️ Pitfalls to Avoid
Sizing on price alone catches up with you in month three, when encrypted checking gets turned on and the unit that looked adequate starts to struggle.
🔌 Guidelines & Sizing
If fibre runs between the firewall and the core switch, order the transceivers and patch leads together and matched. A mismatched pair will link up happily and then drop packets quietly for weeks.
📈 Upgrade Triggers
The internet feels slow every afternoon and restarting the router has quietly become somebody's daily job.
Frequently Asked Questions
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. 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. Our internet keeps dropping. Will this fix it?
It will not repair a bad line, but it can stop the drop from stopping work. Connect two links - a fibre leased line and a broadband or 4G backup, say - and the box watches both and shifts traffic onto the healthy one on its own (SD-WAN). Calls, Tally sessions and cloud apps ride whichever link is cleanest at that moment. If a single line is dropping five times a day, the real fix is a conversation with your ISP; this only makes the drops survivable.
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. 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.
💡 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.
