What should a firewall protect against?
A firewall should help your team get on with their day-to-day work while keeping your business safe from threats like unauthorised access, ransomware and data loss.
It should act as a barrier between your network and the internet and helps keep unwanted traffic out while allowing legitimate activity through.
But the key is getting the balance right for how your business actually works.
If the rules are too relaxed, you leave the door open to potential threats. If the rules are too restrictive, you could end up disrupting everyday tasks like video calls, payment processing or remote access.
It’s about protecting your business without making everyday work harder than it needs to be.
