Five branches, five separate internet bills, and no single place to see what any of them is doing. That is the state most growing retail and clinic chains are in by the time they ring us. Once every site runs a firewall from the same family, the branches join into one private network over the internet and you watch the lot from a single screen. A new shop then takes an afternoon to bring online instead of a week, and we handle the sizing, the licences and the on-site commissioning across Kolkata.
🤝 Sophos Deployment, Migration and Handover around Khanna
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 Khanna 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.
✅ 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 Khanna 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
Putting a next-generation firewall into a working office in Khanna is mostly planning, not screwdriver work. We start by listing what actually runs on your network - Tally, the CCTV recorder, the biometric machine, the two broadband lines nobody documented - before a single rule gets written. Only then do we agree a cutover slot, usually after hours, with an agreed way back if something misbehaves.
Our engineers cover the following, across offices in and around Kolkata:
▪Separate Lanes for Guest WiFi, CCTV and Accounts (VLANs)
▪Emergency Hardware Replacement and Config Restore
▪A Bouncer for Your Website and Mail Server (WAF)
▪Unknown-Attachment Checks and Quarantine Rules
*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: Nearly every website is encrypted now, and so is most of the malware arriving through them. The firewall briefly unwraps that encryption to look inside, and does the heavy maths in dedicated hardware so browsing stays quick.
🔍 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.
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.
🔹 POWER
Draws little enough that a small office UPS carries it and the modem straight through a cut.
🔹 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.
🔹 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.
🔹 LOAD
Antivirus, intrusion checks and encrypted-site scanning can all run together without the branch tunnels slowing to a crawl.
🔹 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.
🔹 FANS
Cooling modules also pull out from the front without a shutdown, which matters the night a bearing starts whining.
🔹 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.
🔹 WHO CONTROLS IT
Every rule stays at head office. The branch cannot change a thing, which is usually the whole point.
🔹 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.
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).
🔹 WHO IT SUITS
Schools, hotels, hospitals and factories - anywhere the camera and phone count keeps climbing.
🔹 IF SOMEONE MAKES A LOOP
Plugging both ends of one cable into the same switch normally floods the whole office; the switch spots it and shuts that port.
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 IT'S FOR
WiFi that holds up when twenty phones and laptops crowd into one meeting room.
🔹 WALKING AROUND
Handover between units is quick enough that a call on WiFi survives a walk from the cabin to the shop floor.
🔹 POWER
The network cable carries power up to the ceiling, so no electrician and no plug point above the false ceiling (PoE).
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.
🔹 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).
🔹 WHAT IT NEEDS
A small agent on the laptop and the gateway running on your firewall or from the cloud console.
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.
🔹 WHO IT SUITS
Any office where users are local administrators, or where pen drives still move between machines daily.
🔹 SERVERS
The Tally server, ERP box and file server get settings tuned so the month-end run does not slow to a crawl.
🔹 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 PEOPLE REGRET
Letting it run dry for a couple of months to save money, then paying for reinstatement plus the clean-up afterwards.
🔹 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.
🔹 MULTI-YEAR TERMS
A three-year term fixes the cost and removes two rounds of buy orders, approvals and chasing.

📖 Common Failures and How We Fix Them around Khanna
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 Khanna. 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: 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.
🧾 Feature List and Technical Detail in and around Khanna
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.
The family runs from small desktop units for one office up to rack appliances built for a head office of several hundred people and multiple internet lines. The operating system is the same across the range, so what your team learns on a small unit still applies on a large one. Growing is a change of model, not a change of habits.

Firmware Signing and Secure Boot: Sophos Standards
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).
If you pay for two internet connections, both should be earning their keep. Each one is measured continuously for loss, delay and wobble, and sessions move between them according to rules you set, so voice and billing get the healthy one. Branch tunnels rebuild themselves after a cut is repaired, with nobody logging in (SD-WAN).

⚡ Handling Peak Load at Month-End for businesses in Kolkata
Checked while a hundred staff browsed https sites at the same moment.
BENEFITS YOU WILL NOTICE IN ONE LIST
COMMON COMPLAINTS - THE SHORT LIST
✓You can see which application is eating the bandwidth at 3pm and cap just that one, without blocking the whole internet.
—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).
—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.
✓Selected rack models keep the wire connected even if the appliance loses power, so a production line does not halt (bypass ports).
—A proper 19-inch rack with front-to-back airflow is expected. A firewall balanced on a cupboard shelf runs hot and dies early.
✓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.
✓"We turned virus scanning off because everything crawled" is the most common thing we hear when taking over an old box; here that switch can stay on for good (Xstream FastPath offload).
—Firmware updates drop sessions briefly. On a single unit that means a late-night window agreed with the people who actually work late.
💡 Engineering Fact: The settings screen and the traffic handling run as separate parts of the same system. That split is why saving a new rule at eleven in the morning does not interrupt the people already working.

Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Khanna
🛠️ Workflow Setup
The unit is built and tested on our bench before it ships, with your rules, users and branch links already in it, so what arrives is shaped like your business rather than the factory default.
⚠️ Pitfalls to Avoid
Skipping the MTU check on a new leased line produces a fault that shows only on big files and only over the branch link, which is days of blame before anyone finds it.
🔌 Guidelines & Sizing
Leave a blank vented panel above and below a rack unit. Heat is what actually kills these boxes through an Indian summer, far more often than the electronics failing on their own.
📈 Upgrade Triggers
You bought a second internet line for backup, and switching to it still means a person crawling under a desk to move a cable while everyone waits.
🛠️ Fitting the Appliance into a Rack That Is Already Full near Khanna
Read these before the cutover date is fixed. Most of them are far cheaper to get right now than to fix later with a rack full of live cables in Khanna.
🏢 Data Migration & Cutover - A Timeline around Khanna
🔹Clean fibre ends with an optical pen before seating them in SFP+ slots. Most links that flap every few minutes on dusty sites near Khanna are carrying a speck of dust, not a faulty module.
🔹Before switching on inspection of encrypted sites, push the firewall's certificate out to every company computer through Group Policy. Do that first and you save yourself a morning of browser warnings.
🔹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 Khanna, a unit wedged between two servers will throttle by May whatever the datasheet promises.
Frequently Asked Questions
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. 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 Khanna.
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. 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.
💡 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.
