What is a Firewall and why your business still needs one in 2025
Firewalls are not glamourous. They rarely make headlines, and when they work well you barely notice them. Yet in 2025, when your business depends on cloud apps, remote users, and always-on services, the humble firewall still carries a lot of weight. Think of your network like a building. You have doors, corridors, lifts, and a steady stream of visitors. A firewall is the front desk and the security team. It lets the right people in, keeps the wrong people out, and spots odd behaviour before it becomes a problem.
