Description: A redundant firewall is a network security configuration that uses multiple firewalls to ensure service continuity and data protection. This strategy is based on the idea that by implementing several firewalls in parallel, the risk of individual failures can be mitigated. If one firewall fails or is compromised, the others can continue to operate, ensuring that the network remains protected. Redundant firewalls can be configured in different modes, such as active-active, where both firewalls operate simultaneously, or active-passive, where one is on standby to take over in case the other fails. This redundancy not only improves system availability but also allows for greater flexibility in managing network traffic and implementing security policies. In various environments, where information security is critical, redundant firewalls are essential for protecting digital assets and maintaining trust. Additionally, their implementation can be part of a broader strategy for high availability and disaster recovery, making them a key tool in modern network architecture.
