Network Firewalls
Network firewalls are essential security devices designed to protect computer networks from unauthorized access, cyber threats, and malicious attacks. They act as a barrier between trusted internal networks and untrusted external networks, such as the internet. Firewalls monitor and filter incoming and outgoing traffic based on predefined security rules, allowing legitimate data to pass through while blocking potentially harmful traffic. By implementing network firewalls, organizations can safeguard sensitive information, ensure data integrity, and maintain a secure and compliant IT infrastructure. Whether deployed as hardware appliances, software solutions, or cloud-based services, firewalls play a critical role in maintaining network security and resilience.
