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 Purbalaya, and we run the speed test in front of you before we hand the box over.
🏢 Local Engineers for Sophos Next-Gen Firewall for Business Networks in and around Purbalaya
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 Purbalaya.
🎯 Good Reasons to Move Off Your Current Setup in and around Purbalaya
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 Purbalaya.
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 Purbalaya
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 expect a few calls in the first fortnight after handover, and we plan for them. A blocked website, a vendor VPN that needs an exception, a printer that stopped talking to the accounts machine - all normal, all part of the commissioning period rather than billed as fresh visits. Past that window, support runs under whichever contract you have chosen.
What you can hand over to us, on a per-job or annual contract basis:
▪Fibre Links Between Buildings, Fitted and Terminated (10GbE Transceivers)
▪Two or Three Internet Lines Used Together, Switching by Themselves (SD-WAN)
▪Firewall Supply, Setup and Commissioning
▪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: 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.
🛡️ 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 Purbalaya.
📋 Available Options and Typical Fit 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.
🔹 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.
🔹 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.
🔹 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.
🔹 LOAD
Antivirus, intrusion checks and encrypted-site scanning can all run together without the branch tunnels slowing to a crawl.
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.
🔹 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.
🔹 IF IT FAILS
Swap the unit. The replacement pulls the same configuration down on its own, so there is nothing to set up again.
🔹 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.
🔹 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).
🔹 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.
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.
🔹 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'S EXTRA
Licensed by number of users, so a five-person accounts team is paid for as five, not as the whole staff.
🔹 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.
🔹 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.
🔹 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).
🔹 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.
🔹 BUNDLES
One combined subscription covers most of the protection at a better rate than buying the modules one by one.
🔹 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.

💬 Where the Datasheet and Reality Differ in and around Purbalaya
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: Hosting your own website or mail server means the world can knock on your door. The firewall can stand in front of it, reading each request and turning away the standard tricks attackers try first.
🛠️ 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.
🛠️ Rollout Across Branches - A Walkthrough across Kolkata
🔹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.
🔎 Capacity, Limits and Sizing Guide 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.

Sophos Thermal Design and Internal Board Layout
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).

Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Purbalaya
🛠️ 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.

PRACTICAL GAINS AT A GLANCE
PREPARATION YOU WILL NEED SET OUT PLAINLY
✓Hosting your own website or mail server is what turns your office address into a target; a filter in front of it absorbs the standard break-in attempts before they reach the server (Web Application Firewall).
—VPN speed between branches is capped by the upload speed your ISP gives you. No firewall can invent bandwidth the line does not have.
✓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).
—Without a UPS, every power cut becomes an unplanned reboot. Repeat that through a monsoon week and you are risking the hardware, not just the uptime.
✓Threat lists refresh on their own through the day, so protection never depends on somebody remembering to update it.
—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.
✓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).
—In-depth logging fills the internal disk if nobody sets rotation or ships the logs off the box.
✓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).
—Fibre ports ship empty. Transceivers or DAC cables are a separate buy, and the wrong part simply will not link up.
💡 Engineering Fact: Every minute or so the box quietly tests each internet line by pinging a known point and timing the reply. When one line starts dropping packets, calls shift to the other before anybody in the office complains.
⚡ SYSTEM DEPLOYMENT ARCHITECTURE
Ready to secure your premises in Purbalaya?
Get comprehensive structured network setups, professional hardware alignment, and authorized warranty support allocations natively.
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. 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. 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. We are a 20-person office. Is this overkill for us?
Not really - the model matters far more than the brand. A small office on an entry-level unit gets the same scanning engine as a large one; it simply handles fewer users and less traffic. Overkill is buying a rack-sized box with modules you will never switch on, which does happen. Tell us your staff count, your line speed, whether you host anything in-house, and how many branches there are, and we will point at the smallest thing that fits comfortably.
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.
💡 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.
