Firewall
Keeping your business safe from online threats by controlling who and what can access your network.
A Firewall is a security tool that monitors and controls the data traffic coming into and leaving your network. It acts like a digital barrier, protecting your business systems from unauthorised access, viruses, and cyber threats.
There are two main types:
- Hardware Firewalls – Physical devices that protect your network
- Software Firewalls – Programmes installed on individual computers or servers
Firewalls use rules to decide what data is safe and what should be blocked. They help prevent hackers, malware, and unauthorised users from accessing your systems.
Why it matters: A firewall is one of the most important defences in your cybersecurity setup. It ensures your sensitive business data stays secure and helps you comply with data protection regulations.
