Why does the office internet crawl every afternoon, even though you pay for a fast line? Nine times out of ten the firewall is the bottleneck, because it starts checking encrypted traffic and runs out of processing power by mid-day. The Sophos Next-Gen Firewall for Business Networks splits that work across two chips, so routine traffic flows straight through while the security scanning happens alongside it. We size and install these for offices in and around Mirzapur, and we run the speed test in front of you before we hand the box over.
🏢 Annual Maintenance and Renewal for Sophos Next-Gen Firewall for Business Networks in and around Mirzapur
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.
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.
🎯 Good Reasons to Move Off Your Current Setup in and around Mirzapur
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 Mirzapur.
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.
Factory Floor and Office Traffic, Kept Apart near Mirzapur
A 40-bed hospital in Kolkata ran patient records, an imaging machine and visitor Wi-Fi over a single flat network, which its insurer had begun asking questions about. We separated the three, put the appointment portal behind an application filter and restricted the records system to staff logins only. Visitors still get Wi-Fi in the waiting area, fenced off from everything clinical. The insurer's questionnaire was answered with a network diagram instead of a promise.
🛡️ WHAT WE DOCUMENT AND HAND OVER
Our Approach to Rules, Testing and Rollback
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:
▪A Bouncer for Your Website and Mail Server (WAF)
▪Two or Three Internet Lines Used Together, Switching by Themselves (SD-WAN)
▪Infected Laptops Cut Off Automatically (Synchronized Security)
▪Out-of-Hours Switchover from Your Old Firewall
*Disclaimer: installation, migration and audit work is charged on a per-job or contract basis. Warranty claims on the hardware continue to run through the manufacturer's own channels.*
💡 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.
🛡️ TWO LINES, ONE GATEWAY
Tired of a branch going dark every time one line is cut? Our engineers design multi-line and branch-to-branch links for businesses in and around Mirzapur.
📋 Pick the Right Variant Without Overspending across Kolkata
The table below covers sizes, interfaces and what fits which office:
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.
🔹 PORTS
Six to eight network sockets, with a fibre slot on the bigger models for a leased line.
🔹 POWER
Draws little enough that a small office UPS carries it and the modem straight through a cut.
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.
🔹 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.
🔹 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.
🔹 SIZE
Two rack units, considerably heavier, and it needs proper rails in a full-depth cabinet rather than a shelf.
🔹 WHO IT SUITS
Data centres, large campuses and companies holding tens of thousands of live connections at peak hour.
🔹 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.
🔹 WHAT STAFF SEE
Tally, the shared folder and the head office printer open exactly the way they do at the main location.
🔹 WHAT IT IS NOT
This is not a standalone firewall. It leans on the main appliance, so budget for both together.
🔹 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.
🔹 WHERE IT'S MANAGED FROM
The same cloud dashboard as the firewall, so one login covers both instead of two separate systems.
🔹 LONG RUNS
Fibre uplinks reach an upper floor or a second building without the speed loss a long copper run brings.
🔹 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.
🔹 COVERAGE
Plan by walls, not by wattage. A brick partition or a lift shaft eats more signal than most people expect.
🔹 GUEST WIFI
Visitors get their own name and password, on their own lane, with a login page and a daily expiry if you want one.
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 THE USER DOES
Signs in with the usual office email and password, plus a code on the phone as a second step.
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.
🔹 IF SOMETHING GETS THROUGH
A timeline shows where it came from - the attachment, the pen drive or the website - so the same door gets shut.
🔹 THE PART PEOPLE LIKE
If a machine gets infected, the firewall drops it off the network within seconds, without waiting for anyone to notice (Synchronized Security).
🔹 REPORTING
One list of every machine, whether its updates are current, and which computer is the repeat offender.
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.
🔹 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.
🔹 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.
🔹 AUDITS
An auditor checking your security controls will ask for proof the subscription is live. A lapsed one is a finding.

🔎 How Much It Handles Before It Slows Down for businesses 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.
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.
🏆 CORE PARAMETER🔹 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

🔹 If a laptop gets infectedFirewall isolates it on its own - Synchronized Security heartbeat
Why the Same Model Behaves the Same Everywhere
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).
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).
✉️ SUPPORT DESK
Coordinate custom hardware configurations, AMC maintenance contracts, and site engineering visits directly with authorized integration desks.
🛠️ Cabling, Labels and the Ports You Will Regret Not Marking
A firewall usually fails for physical reasons long before it fails for security ones - heat, dust, bad power, or a cable somebody tugged while pulling out a server.
🛠️ Power and Backup - Site Rules for offices in Mirzapur
🔹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.
🔹Feed the two power supplies from two different circuits, both behind an online UPS, so a single trip during the usual evening voltage swings does not take the gateway down with it.

Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Mirzapur
🛠️ Workflow Setup
We agree the cutover window in advance, usually a Saturday evening or the hour after closing, and we tell you honestly how long the internet will be down. Twenty to forty minutes is typical.
⚠️ Pitfalls to Avoid
Do not run the standby unit's heartbeat cable through a switch. It goes straight from one box to the other, or both units will eventually decide they are in charge.
🔌 Guidelines & Sizing
Two power supplies only help if they are on two different circuits. Both plugged into one strip is a decorative feature, not redundancy.
📈 Upgrade Triggers
Someone in accounts opened a fake invoice email, and the only thing that saved you was that the attachment happened to be broken.
💬 Lessons From Deployments That Went Wrong in and around Mirzapur
The number to size on is throughput with inspection running, not the large figure on the front of the brochure. I have replaced plenty of perfectly good firewalls that were simply one model too small, and the symptom is always identical: features disabled one at a time until the thing is an expensive router. Ask for the figure with intrusion prevention and encrypted inspection both enabled, then leave headroom above it.
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.
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.
💡 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.

TIME AND MONEY SAVED AT A GLANCE
WATCH-OUTS SET OUT PLAINLY
✓The camera recorder nobody has updated since 2019 is the usual way in, so it gets fenced off from the Tally server instead of sharing a flat network with it (VLAN segmentation).
—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).
—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.
✓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).
—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 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).
—Automatic laptop isolation only works where the matching security agent is installed. Machines without it stay invisible to the firewall.
✓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).
—Traffic pushed through anonymising proxies or unmanaged tunnels sits outside these controls, so policy alone will not stop a determined employee.
💡 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.

Q. How do we connect branch offices back to head office?
Two ways, depending on the branch. A small outlet gets a compact plug-in unit that dials home by itself the moment it has any internet - no engineer trip, no configuration done at the branch (Remote Ethernet Device). A larger branch with its own firewall gets a permanent encrypted link between the two sites instead. Either way the branch is treated as another wing of your network, so head-office filtering and rules apply there too, whether it is one shop or twenty across Kolkata.
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. 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 Mirzapur.
Q. How are firmware updates done without taking the office offline?
New firmware installs onto a spare partition and the unit switches over on reboot, so a bad update rolls back to the previous version instead of leaving you stranded. Where a standby pair is running, we update the quiet unit first, move traffic onto it, then update the other, and nobody upstairs notices. On a single unit there is one reboot, a few minutes, which we schedule outside working hours. We also do not push a brand-new release the week it appears - it is allowed to settle first.
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.
💡 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.
