A Firewall is a security system that monitors and controls incoming and outgoing network traffic. It acts like a digital barrier between your internal network and external threats, such as hackers, viruses, or unauthorized access. Used by businesses and individuals, firewalls help protect sensitive data, prevent cyberattacks, and ensure safe internet use. They can be hardware-based, software-based, or cloud-managed, and are essential for maintaining strong cybersecurity in any connected environment.
