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.
📍 Buying Sophos Next-Gen Firewall for Business Networks Without the Guesswork across Kolkata
Buying a firewall two sizes too big is expensive; buying one size too small is worse, because features get switched off one by one until it is just a router. We size the SophosNext-Gen Firewall for Business Networks against your actual staff count, your internet speed and the branches you plan to add. The range runs from a small desktop unit for one office to rack appliances with fibre ports for a head office. Tell us where you expect to be in three years and the quote for your site in Kolkata will be built for that, not for today.
The video call freezes every time somebody in accounts starts a large upload, and by four in the afternoon nobody trusts the internet at all. A SophosNext-Gen Firewall for Business Networks sits between your office and your internet line and decides what gets priority, so meetings and accounting traffic go first while bulk downloads wait their turn. The security checks run on a separate chip, which is why speed does not collapse the moment you switch scanning on (Xstream FastPath offload). We size the unit against your real user count and install it for offices in and around Kolkata.
💡 The Case for Doing It Properly Once across Kolkata
Some businesses can lose an hour. A dispatch desk, a hospital front office or a trading room cannot. Two units can be paired so the standby picks up the live sessions the instant the first one stops, fast enough that a call in progress stays up (Active-Passive HA). Most customers start with one unit and add the second at the next budget cycle, and the pairing is designed to be added later.
Running four branches used to mean four different people making four different mistakes. Every unit reports into one console, so you push the same rules everywhere, see which branch has which problem, and update firmware overnight from your own desk. A new site can be sent the box, plugged into power and internet by anyone on site, and configured remotely. Retail chains and diagnostic labs spread across Kolkata are the usual beneficiaries.
Keeping Four Branches on the Same Rules across Kolkata
A school with roughly nine hundred students found its online exam portal timing out every afternoon, which turned out to be a hostel's worth of video streaming on the same line. We deployed a SophosNext-Gen Firewall for Business Networks with separate staff, student and guest networks, and capped entertainment traffic during school hours only. The very next assessment week finished on time. The IT teacher now changes the rules himself from a browser rather than phoning anyone.
🛡️ HOW WE WORK ON SITE
How We Set Up and Hand Over a Firewall
Every install ends with a written handover: the rule list, the VLAN plan, admin credentials passed on securely, and a one-page sheet covering what to do if. Offices near Kolkata often have three people who each know a piece of the network and nobody who knows all of it. That document exists so the network does not turn into a problem the day someone resigns.
A short list of what we are usually called in for:
▪A Bouncer for Your Website and Mail Server (WAF)
▪Infected Laptops Cut Off Automatically (Synchronized Security)
▪Emergency Hardware Replacement and Config Restore
▪Encrypted Website Scanning and Certificate Rollout
*Note: every site visit, configuration change and troubleshooting session listed here is a paid service, quoted in advance, and separate from any support you receive directly from the manufacturer.*
💡 Engineering Fact: A firewall remembers conversations, not just packets. Because it noted your request going out, the reply is allowed back in - and a packet claiming to answer a question nobody asked is dropped without ceremony.
📋 FIREWALL SIZING
Not sure which model suits an office of your size in Kolkata? Send us your user count and internet speed and we will come back with a size, a price, and the reasoning behind both.
Model-by-model details, including cluster support and licence tiers:
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.
🔹 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.
🔹 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.
🔹 HEAT
Front-to-back cooling copes with a warm server room, though we still insist on a working AC and a clean filter.
🔹 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.
🔹 IF IT FAILS
Runs as a pair, and some sites run both units live so neither one sits idle (Active-Active clustering).
🔹 BUSY NETWORKS
Sized for the case where thousands of people, cameras and machines all hold connections open at the same moment.
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.
🔹 BUILD
Metal body, low power draw, no fan, so it survives a dusty stores room far better than a plastic consumer router.
🔹 HOW IT CONNECTS
An encrypted tunnel back to the main firewall makes the branch behave like another room at head office.
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.
🔹 WHAT IT'S FOR
Turning one network point into eight, twenty-four or forty-eight, with a proper record of what is plugged where.
🔹 IF A PORT MISBEHAVES
You can spot the guilty port and shut it from the screen, instead of unplugging cables one at a time.
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.
🔹 WHERE IT'S MANAGED FROM
One cloud console shows every unit, who is connected and which one is the busiest.
🔹 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.
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.
🔹 RECORDS
Each session is logged by person and by application, which is normally the exact evidence an audit wants.
🔹 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.
🔹 SERVERS
The Tally server, ERP box and file server get settings tuned so the month-end run does not slow to a crawl.
🔹 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.
🔹 BUNDLES
One combined subscription covers most of the protection at a better rate than buying the modules one by one.
🔹 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.
🔹 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.

Rule order matters more than people expect. Put the busy, trusted flows - internal routing, your ERP, your voice traffic - near the top of the policy list so those packets reach the fast path early instead of walking the whole table. On a busy site this shows up as lower processor load and fewer complaints, without weakening a single security setting. Reordering is a ten-minute job that most inherited configurations badly need.
Cloud-only filtering protects users while they are online through that service, but traffic between machines inside your own office never passes through it - and internal spread is exactly how ransomware travels once it is in.
A plastic desktop security box is fine until the day it is not: no second power supply, no standby unit, no fibre port, and a fan that gives up in a warm room. The metal rack units are designed for continuous running.
💡 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.

WHAT WORKS IN DAILY USE - THE HIGHLIGHTS
WHO IT DOES NOT SUIT - THE HONEST VERSION
✓You can see which application is eating the bandwidth at 3pm and cap just that one, without blocking the whole internet.
—Web application firewall rules need tuning in the first fortnight, or they will block a legitimate in-house script and the firewall will get the blame.
✓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).
—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.
✓"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).
—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.
✓Selected rack models keep the wire connected even if the appliance loses power, so a production line does not halt (bypass ports).
—Firmware updates drop sessions briefly. On a single unit that means a late-night window agreed with the people who actually work late.
✓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).
—Rackmount units are audibly loud under load. Put one in an open office and somebody will complain by the second week.
💡 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.

🛠️ Where the Box Should Actually Sit: Rack and Room Notes for Kolkata
Before anybody unwraps the appliance, walk the room once with this list and confirm that power, earth and rack space are genuinely ready.
📌 User Training & Handover - Our Standards for busy workplaces
🔹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.
📊 Licence Tiers and What Each One Covers for offices in Kolkata
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.
🏆 CORE PARAMETER💾 Log storage on boardGood for large-scale setups SSD for local reporting and audit trails
🔹 What's insideMulti-core processor plus a separate Xstream security chip (NPU)
🔹 Sizes you can buyFanless desktop, 1U rackmount, 2U rackmount
🔌 Spare power supplyOptional on the smaller rack models, fitted as standard and hot-swappable on the larger ones
🔹 Unknown attachmentsOpened in a cloud sandbox before they reach a user
🔹 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
Factory Testing Before the Box Ships
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).

Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Kolkata
🛠️ 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. 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. 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. 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. Can guest WiFi, CCTV and accounts be kept apart?
Yes, and it is one of the more valuable things to do. The network is split into separate lanes so a visitor's phone, the camera recorder and the accounts server cannot see one another, with the firewall inspecting anything that crosses between them (VLAN segmentation). This is what stops a single infected machine from wandering across the whole office. Cameras and other smart devices deserve their own lane in particular, because they are rarely updated. It needs some planning of the switch layout, which is why we ask for a site visit first.
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.
💡 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.
