How often should WAF security rules be updated?

Organizations should update WAF security rules continuously to keep pace with emerging threats. The frequency of updates depends on several factors, including the organization's threat landscape, the criticality of the protected applications, and the agility of threat actors. Ideally, WAF providers or security teams should update the rules at least weekly or as soon as they identify new vulnerabilities or exploits. Automating updates and integrating threat intelligence feeds can help ensure that the WAF always equips itself to handle the latest threats.
