Firewall or antivirus — what does a small office actually need?
Where endpoint protection stops being enough, and what changes when you have more than ten people.
A home PC can live on antivirus and luck. An office cannot.
The moment you have shared files, a router, a CCTV recorder, and staff who click links on their phone, one infected laptop is no longer “that one machine.” It can become a path into the rest of the network.
Many small offices in Goa buy a consumer antivirus, tick a box and assume they are covered. That may be enough for one or two computers. Once the business starts growing, the gaps become harder to ignore.
Start with the basics
Every Windows PC should have a current endpoint protection solution, regular security updates and real-time scanning enabled.
If a machine is still running a trial antivirus that expired months ago, treat it as unprotected.
But endpoint protection only protects the device itself. It does not control what is allowed into the network in the first place.
Then add the door
That is where a firewall comes in.
A firewall sits between your internal network and the internet. It controls what traffic is allowed in and out, helping separate your business network from the wider internet.
For a small office, this becomes particularly useful when you have multiple users, shared resources, remote access, guest Wi-Fi, CCTV, servers or a NAS.
The goal is not simply to install a firewall because a checklist says you should. It is to reduce unnecessary exposure and control how your network communicates.
What we typically check on a first visit
Before recommending anything, we look at how the network is actually being used.
- Are all PCs on the same network with file sharing wide open?
- Is the CCTV recorder reachable from the internet simply for convenience?
- Do staff use shared Wi-Fi credentials for work and personal devices?
- Is guest Wi-Fi separated from business systems?
- Are backups stored separately from the computers they are protecting?
- Is the network equipment kept somewhere secure?
These questions often tell us more than the number of computers on the desk.
A simple rule
Under ten people, a properly configured endpoint protection solution, current software, secure Wi-Fi and basic network controls can often provide a sensible starting point.
As the business grows — or if you start handling sensitive data, running servers, using cloud applications heavily, providing remote access or connecting multiple locations — your security requirements change too.
The answer is not always “buy a bigger firewall.”
It is about understanding what needs protecting, where the risks are and how your systems are connected.
Start with what you have
If you want to understand where your office currently stands, start with the basics.
Check your computers, router or firewall, Wi-Fi setup, CCTV access, backups and software updates. A simple review can often identify weaknesses before they become expensive problems.
If you want this checked for your office, send us your current setup and we can help you understand what needs attention.
