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 Kanthi (Contai), 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 Kanthi (Contai)
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 Kanthi (Contai)
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 Kanthi (Contai).
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 Kanthi (Contai)
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
Putting a next-generation firewall into a working office in Kanthi (Contai) 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:
▪Firewall Supply, Setup and Commissioning
▪A Bouncer for Your Website and Mail Server (WAF)
▪Encrypted Website Scanning and Certificate Rollout
▪Branch-to-Branch and Work-from-Home VPN Setup
*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 Kanthi (Contai).
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.
🔹 WHAT'S EXTRA
A bracket kit is sold separately if you later want it screwed into a rack instead of standing on a table.
🔹 TWO INTERNET LINES
Keep fibre and a broadband backup plugged in together; when one drops, the switch across happens on its own (SD-WAN).
🔹 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).
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.
🔹 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.
🔹 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).
🔹 FIBRE PORTS
Ten-gigabit fibre sockets go straight into your core switch with no converter box in the middle (SFP+).
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.
🔹 FANS
Cooling modules also pull out from the front without a shutdown, which matters the night a bearing starts whining.
🔹 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.
🔹 WHO CONTROLS IT
Every rule stays at head office. The branch cannot change a thing, which is usually the whole point.
🔹 WHAT STAFF SEE
Tally, the shared folder and the head office printer open exactly the way they do at the main location.
🔹 IF IT FAILS
Swap the unit. The replacement pulls the same configuration down on its own, so there is nothing to set up again.
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 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.
🔹 WHAT IT'S FOR
Turning one network point into eight, twenty-four or forty-eight, with a proper record of what is plugged where.
🔹 LANES
Cameras, billing machines, guest WiFi and staff laptops stay apart on the same physical cabling (VLANs).
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.
🔹 WHO IT SUITS
Schools with tablets, hotels, co-working floors, and warehouses running handheld barcode scanners.
🔹 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.
🔹 WHAT THE USER DOES
Signs in with the usual office email and password, plus a code on the phone as a second step.
🔹 WHO IT SUITS
CA firms in filing season, sales teams, and any business whose auditor asks who opened what and when.
🔹 CONTRACTORS
A vendor can be given one server for a fixed number of days, after which the access simply stops.
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.
🔹 WHAT IT REPLACES
The free antivirus that quietly expired two years ago and the paid one nobody renewed after the IT person left.
🔹 WHAT'S EXTRA
Mail and mobile device protection are separate add-ons and are worth pricing at the same time.
🔹 RANSOMWARE
It watches for a program that suddenly starts encrypting files, stops it, and puts the changed files back.
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.
🔹 AUDITS
An auditor checking your security controls will ask for proof the subscription is live. A lapsed one is a finding.
🔹 MULTI-YEAR TERMS
A three-year term fixes the cost and removes two rounds of buy orders, approvals and chasing.
🔹 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.

TIME AND MONEY SAVED AT A GLANCE
WATCH-OUTS SET OUT PLAINLY
✓Office WiFi points are managed from the same screen as the firewall, which saves buying a separate controller.
—This is not a easy to set up device. Someone has to own the rule set, review it, and clear out the rules that were added temporarily two years ago.
✓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).
—Firmware updates drop sessions briefly. On a single unit that means a late-night window agreed with the people who actually work late.
✓The steel case is shaped to pull air front to back, which is what keeps the unit alive in a warm, dusty cabinet.
—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.
—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.
✓Login names come from your existing Microsoft accounts, so reports name people instead of IP addresses (Active Directory, LDAP, SAML 2.0).
—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: Protected laptops send the firewall a one-line health note every few seconds. The moment one of those notes turns red, the firewall stops that machine talking to anyone else on the network.

Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Kanthi (Contai)
🛠️ 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.
🛠️ 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.
🛠️ Data Migration & Cutover - Site Rules for offices in Kanthi (Contai)
🔹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.
🔎 Feature List and Technical Detail 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.

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).

💬 Lessons From Deployments That Went Wrong in and around Kanthi (Contai)
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.
Frequently Asked Questions
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.
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. What paperwork does this give us at audit time?
Logs and reports showing who went where, what was blocked, and when someone changed a rule - which is usually what an ISO, RBI or customer security audit is really asking to see. Reports can be scheduled and mailed to a named person every month, so nobody has to remember. Bear in mind that keeping logs for a long period needs storage, either on the appliance or on a central reporting service, and that is a decision better made before the auditor arrives than after. We set the reporting up during installation.
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: Switch full security scanning on in most routers and the whole office slows down. This one avoids that by handing routine, already-checked traffic to a second chip while the main processor does the inspecting.
