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.
✅ Buying Sophos Next-Gen Firewall for Business Networks Without the Guesswork anywhere in 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 Dighi Road.
🧠 What Changes in the First Month with a growing team
Owners rarely want to read firewall logs. They want three answers: is anything getting in, who is eating the internet line, and are we exposed anywhere obvious. Scheduled reports arrive by email in plain tables a manager can read without a translator, and the technical detail stays underneath for whoever needs it. When an insurer or a customer's compliance team asks about your controls, you have something real to send.
Very few offices stay the same size for the working life of a firewall. Start with one internet line and forty users, and the same unit will later carry a second line, branch tunnels, remote staff and a guest network - licensed features rather than extra boxes. We size for headroom instead of for today's headcount, which is why our quotes for sites in Dighi Road usually look one step ahead. When you do outgrow it, the configuration exports into a larger model rather than being retyped.
Retail Counters, Card Machines and a Line That Keeps Choking
A trading house near Dighi Road could never close month-end billing on time, partly because the accounts server was reachable from every machine in the building, including two riddled with adware. We fenced that server behind its own rules, tied access to office logins rather than to machines, and put web filtering in front of the general staff network. The month-end run finished on schedule for the first time in over a year. Two infected desktops turned up in the first week's report and were cleaned the same day.
🛡️ TESTING, CUTOVER AND ROLLBACK DISCIPLINE
How We Size, Quote, and Sometimes Say No
We are an independent integrator, not the manufacturer's helpdesk, and it is worth being clear about that up front. Our engineers configure the appliance, connect it to your switches, test the failover by pulling a cable rather than trusting the manual, and stay reachable the next working morning. Anything that cannot be fixed in software goes to Sophos through the proper channel, and you are told exactly where it stands.
Services delivered on site and remotely, priced up front:
▪Unknown-Attachment Checks and Quarantine Rules
▪Annual Maintenance Contracts and Response-Time Cover
▪Branch-to-Branch and Work-from-Home VPN Setup
▪Infected Laptops Cut Off Automatically (Synchronized Security)
*Notice: rates for on-site engineering, cabling and rule audits are shared before work starts. We do not act as, and are not an extension of, the manufacturer's support desk.*
💡 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.

🏷️ Pick the Right Variant Without Overspending for growing companies
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.
🔹 PORTS
Six to eight network sockets, with a fibre slot on the bigger models for a leased line.
🔹 TWO INTERNET LINES
Keep fibre and a broadband backup plugged in together; when one drops, the switch across happens on its own (SD-WAN).
🔹 GUEST WIFI
Visitors and staff run on different networks, so a guest laptop never sees the accounts machine (VLAN).
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 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).
🔹 LOAD
Antivirus, intrusion checks and encrypted-site scanning can all run together without the branch tunnels slowing to a crawl.
🔹 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.
🔹 IF IT FAILS
Runs as a pair, and some sites run both units live so neither one sits idle (Active-Active clustering).
🔹 VERY FAST PORTS
Twenty-five and forty-gigabit fibre sockets, so the firewall is never the narrow point between server rows.
🔹 WHO IT SUITS
Data centres, large campuses and companies holding tens of thousands of live connections at peak hour.
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.
🔹 HOW IT CONNECTS
An encrypted tunnel back to the main firewall makes the branch behave like another room at head office.
🔹 BACKUP LINE
A second connection, including a 4G or 5G dongle, can be attached where the local broadband is unreliable.
🔹 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.
🔹 LANES
Cameras, billing machines, guest WiFi and staff laptops stay apart on the same physical cabling (VLANs).
🔹 WHAT IT'S FOR
Turning one network point into eight, twenty-four or forty-eight, with a proper record of what is plugged where.
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.
🔹 GUEST WIFI
Visitors get their own name and password, on their own lane, with a login page and a daily expiry if you want one.
🔹 POWER
The network cable carries power up to the ceiling, so no electrician and no plug point above the false ceiling (PoE).
🔹 WHAT IT'S FOR
WiFi that holds up when twenty phones and laptops crowd into one meeting room.
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.
🔹 WHO IT SUITS
CA firms in filing season, sales teams, and any business whose auditor asks who opened what and when.
🔹 WHAT'S EXTRA
Licensed by number of users, so a five-person accounts team is paid for as five, not as the whole staff.
🔹 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.
🔹 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.
🔹 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.
🔹 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.
🔹 WHAT IT'S FOR
Keeping virus updates, web filtering, sandbox checks and vendor support current on a firewall you already own.

🛠️ 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.
📈 Upgrade Triggers
Your bank, your largest customer or an auditor has begun asking for a written network security policy and logs that back it up.
📋 How Much It Handles Before It Slows Down for small teams
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.
💾 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)
🔹 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
🔹 If a laptop gets infectedFirewall isolates it on its own - Synchronized Security heartbeat
🔹 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
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).

📋 Site Survey & Planning - Our Standards for busy workplaces
🔹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 Dighi Road, 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.
💡 What Our Team Sees on Site after years of site visits
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: An attachment nobody has seen before is opened first inside a throwaway computer in the cloud. If it starts encrypting files or hiding from the operating system, it is never delivered to your staff.

WHAT WORKS IN DAILY USE - FOR BUYERS
WHO IT DOES NOT SUIT - A QUICK LIST
✓The camera recorder nobody has updated since 2019 is the usual way in, so it gets fenced off from the Tally server instead of sharing a flat network with it (VLAN segmentation).
—In-depth logging fills the internal disk if nobody sets rotation or ships the logs off the box.
✓Selected rack models keep the wire connected even if the appliance loses power, so a production line does not halt (bypass ports).
—VPN speed between branches is capped by the upload speed your ISP gives you. No firewall can invent bandwidth the line does not have.
✓An ageing core switch and a new fibre run can both plug into the same box, so nobody is forced into replacing the switch in the same month (port mix varies by model).
—Running BGP or OSPF routing is genuine network engineering. Budget for a competent hand on cutover day instead of treating it as a weekend experiment.
✓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).
—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.
✓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).
—Firmware updates drop sessions briefly. On a single unit that means a late-night window agreed with the people who actually work late.
💡 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.
⚡ SYSTEM DEPLOYMENT ARCHITECTURE
Ready to secure your premises in Dighi Road?
Get comprehensive structured network setups, professional hardware alignment, and authorized warranty support allocations natively.
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. Can our staff still work from home?
Yes, and for many buyers that is half the reason for buying it. Staff install a small app, sign in with their office username plus a second factor, and then work as though they were at their desk (IPsec or SSL VPN). For anyone who cannot install software there is a browser-based route into a remote desktop or a shared folder. One limit worth naming: home broadband quality still sets the speed, and no firewall can make a weak line at somebody's house behave.
Q. How do we connect branch offices back to head office?
Two ways, depending on the branch. A small outlet gets a compact plug-in unit that dials home by itself the moment it has any internet - no engineer trip, no configuration done at the branch (Remote Ethernet Device). A larger branch with its own firewall gets a permanent encrypted link between the two sites instead. Either way the branch is treated as another wing of your network, so head-office filtering and rules apply there too, whether it is one shop or twenty across Kolkata.
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 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: The reason a visitor on your guest WiFi cannot reach the accounts server is that the firewall treats them as separate neighbourhoods with no road between them, even though both use the same cabling.
