Work out what one day of a stopped office actually costs you: salaries paid for nothing, dispatches missed, a GST filing that slides past its date. Set that beside the price of a properly sized firewall and the argument tends to finish itself. Ransomware rarely arrives looking like an attack; it walks in through an encrypted website nobody inspected, spreads sideways, and locks the accounts server on a Saturday night. The Next-Gen Firewall for Business Networks looks inside those encrypted sessions and pulls an infected machine off the network by itself, within seconds.
📌 Annual Maintenance and Renewal for Sophos Next-Gen Firewall for Business Networks near Rajarhat Newtown
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.
🌟 Reasons This Works for Small Offices near Rajarhat Newtown
Power in and around Rajarhat Newtown does what it likes: a dip at three, a full cut at seven, a surge when the generator hands back. These appliances are built for continuous duty, and the rack models take two power supplies so you can feed them from two different circuits. We insist on an online UPS and a genuine earth connection before handover, because far more firewalls die of bad power than of hackers. It is a boring detail that quietly decides how long the box lasts.
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.
Warehouse and Dispatch Sites Where Downtime Costs Orders
A CA firm of about thirty staff called us in the week after a partner's laptop encrypted itself during filing season. The replacement gateway opens unknown attachments in a sealed cloud test room before they reach a mailbox, and any machine that starts behaving oddly is pulled off the network automatically. Nothing similar has reached a second computer since. The firm also picked up the access log its bank's audit team had been asking for.
🛡️ STRAIGHT ANSWERS BEFORE YOU COMMIT
Planning, Cutover and What We Leave Behind
Sizing is where most firewall purchases go wrong. We ask how many people are online at once, how much of the traffic is encrypted, whether you intend to inspect it, and whether branches will be joined in - then quote the model that survives that load, even when a smaller one looks better on price. If the honest answer is that you do not need the bigger box, we say so.
The work we take on, listed plainly - all of it chargeable and quoted before anyone starts:
▪Fibre Links Between Buildings, Fitted and Terminated (10GbE Transceivers)
▪Firewall Supply, Setup and Commissioning
▪Branch-to-Branch and Work-from-Home VPN Setup
▪A Bouncer for Your Website and Mail Server (WAF)
*Fair warning: emergency attendance outside contracted hours carries a call-out charge, quoted first, and it remains separate from any manufacturer service line.*
💡 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.
💬 NOT SURE WHERE TO START
Describe the problem in your own words - slow internet, a virus scare, an auditor's question - and we will tell you honestly whether a firewall is even the right answer for your office in Kolkata.
🔖 Ranges Sorted by Office Size for growing companies
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.
🔹 GUEST WIFI
Visitors and staff run on different networks, so a guest laptop never sees the accounts machine (VLAN).
🔹 POWER
Draws little enough that a small office UPS carries it and the modem straight through a cut.
🔹 SIZE
About as big as a thick hardback book, so it fits on a shelf or inside a small wall cabinet.
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.
🔹 FIBRE PORTS
Ten-gigabit fibre sockets go straight into your core switch with no converter box in the middle (SFP+).
🔹 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).
🔹 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.
🔹 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.
🔹 VERY FAST PORTS
Twenty-five and forty-gigabit fibre sockets, so the firewall is never the narrow point between server rows.
🔹 SIZE
Two rack units, considerably heavier, and it needs proper rails in a full-depth cabinet rather than a shelf.
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.
🔹 WHO CONTROLS IT
Every rule stays at head office. The branch cannot change a thing, which is usually the whole point.
🔹 SETUP
Nobody technical travels. The box is couriered, a local hand plugs in power and internet, and it fetches its own settings.
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.
🔹 LONG RUNS
Fibre uplinks reach an upper floor or a second building without the speed loss a long copper run brings.
🔹 WHAT IT'S FOR
Turning one network point into eight, twenty-four or forty-eight, with a proper record of what is plugged where.
🔹 WHERE IT'S MANAGED FROM
The same cloud dashboard as the firewall, so one login covers both instead of two separate systems.
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.
🔹 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.
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.
🔹 WHAT IT NEEDS
A small agent on the laptop and the gateway running on your firewall or from the cloud console.
🔹 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.
🔹 RANSOMWARE
It watches for a program that suddenly starts encrypting files, stops it, and puts the changed files back.
🔹 WHAT IT'S FOR
Guarding the laptops, desktops and servers themselves, rather than only the door they sit behind.
🔹 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.
🔹 BUNDLES
One combined subscription covers most of the protection at a better rate than buying the modules one by one.
🔹 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.
🔹 AUDITS
An auditor checking your security controls will ask for proof the subscription is live. A lapsed one is a finding.

📌 Lessons From Deployments That Went Wrong near Rajarhat Newtown
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: During a call, the firewall holds a large file download back by a fraction of a second so the voice packets go first. That tiny delay is why the download still finishes and nobody sounds like a robot.
📌 Key Figures Every Buyer Should Check near Rajarhat Newtown
Rack models take two power supplies and can be paired with a second appliance, so neither a failed power feed nor a failed unit has to stop the office. Failover carries the live sessions across, which is the difference between a blip and a room full of dropped calls. Desktop models trade that redundancy for size and price, and for a single office in Kolkata that is usually the right trade.
On the software side you get web and application filtering, intrusion prevention, mail scanning, a cloud test room for unknown files, and a filter that can sit in front of your own web or mail server. All of it is configured in one place rather than across five separate products. Rules can be written per user group, which is what keeps them readable a year later.
🏆 CORE PARAMETER🔹 Where it's managed fromWeb browser, command line, or the Sophos Central cloud console
🔹 If a laptop gets infectedFirewall isolates it on its own - Synchronized Security heartbeat
🔹 Speed with scanning onA dedicated chip does the inspection, so the drop is far smaller than on an ordinary router - we size the model against the traffic you will actually scan
🔹 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
If a computer in your office starts behaving like an infected one, you should not have to wait for somebody to raise a ticket. The protection software on the machine and the gateway talk to each other continuously, so an unhealthy machine is cut back within seconds and the alert names both the machine and the person using it (Synchronized Security).
Open one login and you see every site you run, with the same rules, the same scheduled firmware updates and a stored copy of each configuration. A new branch joins the network without an engineer travelling there to type anything in, which is the difference between a week and an afternoon when you open shop number five (cloud console).

TIME AND MONEY SAVED IN BRIEF
WATCH-OUTS IN ONE PLACE
✓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).
—A proper 19-inch rack with front-to-back airflow is expected. A firewall balanced on a cupboard shelf runs hot and dies early.
✓Selected rack models keep the wire connected even if the appliance loses power, so a production line does not halt (bypass ports).
—Rackmount units are audibly loud under load. Put one in an open office and somebody will complain by the second week.
✓The steel case is shaped to pull air front to back, which is what keeps the unit alive in a warm, dusty cabinet.
—The browser-based remote access screen leans on the user's own laptop and connection. On an old machine over patchy mobile data it feels sluggish.
✓A cheap second broadband connection stops being a spare cable in a drawer and becomes real insurance, because the box moves traffic onto it without anyone logging in (SD-WAN).
—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.
✓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).
—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.
💡 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.

📋 Configuration & Testing - Site Rules for offices in Rajarhat Newtown
🔹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 Rajarhat Newtown, a unit wedged between two servers will throttle by May whatever the datasheet promises.
🔹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.

🛠️ Workflow Setup
If you bought a standby unit, we connect the pair, pull the power from the main one deliberately, and let you watch the second take over while you are standing there.
⚠️ Pitfalls to Avoid
Nobody writes the passwords down, and then the engineer who set it up changes jobs. Get credentials in writing and keep them somewhere two people can reach.
🔌 Guidelines & Sizing
Buy solid copper Cat6, not the cheaper copper-clad aluminium sold under the same label. The thin stuff heats up and resists current, and the drops it causes look exactly like an internet fault.

Your bank, your largest customer or an auditor has begun asking for a written network security policy and logs that back it up.
Frequently Asked Questions
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. 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.
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.
💡 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.
