Firewalls are an essential part of cybersecurity, serving as barriers between trusted internal networks and untrusted external sources, such as the internet. By monitoring incoming and outgoing traffic, firewalls can block malicious activity, such as hacking attempts, malware, and unauthorized access to sensitive data.
Firewalls come in different forms, including hardware, software, and cloud-based solutions, and they can be customized to suit the needs of individual organizations. In addition to protecting networks, firewalls play a key role in ensuring compliance with security regulations and safeguarding personal and business information.
