1. Overhead: HTTP firewalls can be resource-intensive, requiring significant processing power and memory to inspect and analyze HTTP traffic. This can impact network and application performance.
1. False Positives: HTTP firewalls may also generate false positives when attempting to identify malicious traffic. These false positives can lead to legitimate traffic being blocked or slowed down, which can have a negative impact on business operations.
1. Bypassing: Attackers have become adept at bypassing HTTP firewalls using a variety of techniques, including encryption, obfuscation, and tunneling. This means that an HTTP firewall may not be sufficient on its own to protect the network against advanced threats.
1. Complexity: Setting up and configuring an HTTP firewall can be a complex and time-consuming process. This can result in delays and errors, particularly for organizations with limited IT resources.
1. Cost: The cost of deploying and maintaining an HTTP firewall can be significant. This may not be practical or feasible for smaller organizations or those with limited budgets.
