Five branches, five separate internet bills, and no single place to see what any of them is doing. That is the state most growing retail and clinic chains are in by the time they ring us. Once every site runs a firewall from the same family, the branches join into one private network over the internet and you watch the lot from a single screen. A new shop then takes an afternoon to bring online instead of a week, and we handle the sizing, the licences and the on-site commissioning across Kolkata.
🗺️ Sophos Next-Gen Firewall for Business Networks Supply, Setup and Support throughout Kolkata
Almost every site your staff open is now encrypted, and an older firewall waves that traffic straight through unopened. A SophosNext-Gen Firewall for Business Networks can look inside those sessions for hidden malware and still keep pages loading quickly, because the decryption work is done in hardware (TLS 1.3 inspection). You choose what gets opened and what stays private, so banking and medical sites can be left alone. Without it, most of what enters your office is never examined at all.
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.
⭐ Where Sophos Next-Gen Firewall for Business Networks Earns Its Keep around Tala Park
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.
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 Tala Park.
A School Network That Survives Exam Week
A footwear chain with eleven counters across Kolkata kept losing card payments whenever the shop Wi-Fi filled up with customer phones. A firewall at each store now keeps the payment terminals on their own lane with priority on the line, and the guest network cannot see them at all. Queue times at the till stopped being an internet problem. Head office also gained one screen showing which store's connection is misbehaving today.
🛡️ FIELD EXPERIENCE AND ENGINEERING PRACTICE
Why We Write Everything Down
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:
▪Encrypted Website Scanning and Certificate Rollout
▪Standby Unit That Takes Over When One Fails
▪Emergency Hardware Replacement and Config Restore
▪Two or Three Internet Lines Used Together, Switching by Themselves (SD-WAN)
*Please read: we are an independent service provider. Our engineering time is billable, and it is neither a substitute for nor connected to Sophos's own warranty helpdesk.*
💡 Engineering Fact: After the first few packets of a video call or a cloud ERP session, the firewall recognises the conversation and waves the rest through at full speed instead of re-checking every packet of a stream it has already cleared.
⚡ SWITCHOVER AFTER HOURS
Replacing a firewall that is still carrying live traffic in Tala Park? We plan the cutover for after hours, leave the old unit racked until the morning passes quietly, and hand over the rollback steps in writing.
What comes in the box, what costs extra, and what we add on site:
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.
🔹 NOISE
No fan inside. It can live in a reception area or a director's cabin and nobody hears it.
🔹 PORTS
Six to eight network sockets, with a fibre slot on the bigger models for a leased line.
🔹 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.
🔹 WHO IT SUITS
Head offices, hospitals and colleges where two hundred to a thousand people share the connection.
🔹 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.
🔹 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.
🔹 FANS
Cooling modules also pull out from the front without a shutdown, which matters the night a bearing starts whining.
🔹 POWER
Two power packs come fitted as standard, and a dead one slides out and gets replaced while the rest keeps running.
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 IT'S FOR
Very small sites - a warehouse office, a godown, a two-person branch - that still need to be on the head office network.
🔹 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.
🔹 WHERE IT'S MANAGED FROM
The same cloud dashboard as the firewall, so one login covers both instead of two separate systems.
🔹 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).
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.
🔹 WHERE IT'S MANAGED FROM
One cloud console shows every unit, who is connected and which one is the busiest.
🔹 COVERAGE
Plan by walls, not by wattage. A brick partition or a lift shaft eats more signal than most people expect.
🔹 WHO IT SUITS
Schools with tablets, hotels, co-working floors, and warehouses running handheld barcode scanners.
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.
🔹 WHAT IT NEEDS
A small agent on the laptop and the gateway running on your firewall or from the cloud console.
🔹 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).
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.
🔹 WHO IT SUITS
Any office where users are local administrators, or where pen drives still move between machines daily.
🔹 WHAT'S EXTRA
Mail and mobile device protection are separate add-ons and are worth pricing at the same time.
🔹 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.
🔹 WHAT PEOPLE REGRET
Letting it run dry for a couple of months to save money, then paying for reinstatement plus the clean-up afterwards.
🔹 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.

🏢 On-Site Work - The Plan for small and mid-sized teams
🔹Clean fibre ends with an optical pen before seating them in SFP+ slots. Most links that flap every few minutes on dusty sites near Tala Park are carrying a speck of dust, not a faulty module.
🔹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 Tala Park, a unit wedged between two servers will throttle by May whatever the datasheet promises.
🔍 Engineer Notes From Real Installations for offices in Tala Park
Run the HA heartbeat straight between the two appliances. I have seen split-brain clusters caused by nothing more than an intermediate switch rebooting during a power event, after which both units believe they are in charge. A one-metre direct cable removes that entire class of problem. It is the cheapest reliability decision on the whole installation.
Antivirus on each computer only acts once a file has already landed on the machine. A gateway checks it on the way in, and also covers the printers, cameras and shop-floor equipment that cannot run antivirus at all.
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.
💡 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.
📈 Key Figures Every Buyer Should Check across Kolkata
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.
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.
🏆 CORE PARAMETER🔹 If the main unit failsStandby takes over - Active-Passive or Active-Active HA cluster

How Sophos Actually Builds These Units
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).
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).

Turnkey Next-Gen Firewall for Business Networks Metrics Checklist near Tala Park
🛠️ Workflow Setup
The unit is built and tested on our bench before it ships, with your rules, users and branch links already in it, so what arrives is shaped like your business rather than the factory default.
⚠️ Pitfalls to Avoid
Skipping the MTU check on a new leased line produces a fault that shows only on big files and only over the branch link, which is days of blame before anyone finds it.
🔌 Guidelines & Sizing
Leave a blank vented panel above and below a rack unit. Heat is what actually kills these boxes through an Indian summer, far more often than the electronics failing on their own.
📈 Upgrade Triggers
You bought a second internet line for backup, and switching to it still means a person crawling under a desk to move a cable while everyone waits.

CLEAR ADVANTAGES ON ONE PAGE
COSTS BEYOND THE QUOTE - WORTH READING FIRST
✓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).
—Automatic laptop isolation only works where the matching security agent is installed. Machines without it stay invisible to the firewall.
✓You can see which application is eating the bandwidth at 3pm and cap just that one, without blocking the whole internet.
—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.
✓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).
—Fibre ports ship empty. Transceivers or DAC cables are a separate buy, and the wrong part simply will not link up.
✓Login names come from your existing Microsoft accounts, so reports name people instead of IP addresses (Active Directory, LDAP, SAML 2.0).
—Central cloud reporting needs a working outbound connection. At a site with a flaky line, expect gaps in the dashboards.
✓"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).
—To read inside encrypted sites, a certificate has to be pushed to every company laptop first. Personal and unmanaged devices will keep throwing warnings until that is sorted.
💡 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.

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 Tala Park.
Q. What cabling, rack space and power does it need?
Smaller models are desktop-sized and live happily on a shelf; mid-range and larger ones are 1U or 2U and want a standard rack, a clean power feed, and clear air at the front and back. For 10G links inside one rack, short direct-attach copper leads are simplest and cheapest; between floors or cabinets you move to fibre with matching modules at both ends. Heat and dust do more damage in Indian server rooms than anything else, so we check ventilation and, on generator or inverter supply, the power quality too. Everything needed is listed in the quote, so install day holds no surprises.
Q. Can we block YouTube for some staff but not others?
Yes, because rules follow the person rather than the machine. The firewall reads your office login system, so it knows who is sitting there and applies their rules to whichever desk they use (Active Directory or SAML sign-on). Marketing keeps YouTube, the shop floor does not, and a shared computer behaves correctly for each person. You can also cap instead of block - give streaming a thin slice of bandwidth and protect the rest for work.
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.
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: 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.
