According to best practices, what does Palo Alto Networks recommend regarding EDLs?

Palo Alto Networks emphasizes the importance of reviewing EDL (External Dynamic List) capacities and consolidating them as needed to ensure optimal performance and manageability. EDLs are used to dynamically update policies with external information such as IP addresses, URLs, and domains, which contribute to security postures.

Regular review of EDLs allows organizations to identify any lists that may be outdated or overlapping, which can lead to unnecessary complexity and potential performance degradation. By consolidating EDLs, an organization can reduce the number of lists they manage, streamline their operations, and enhance the efficiency of their firewall policies, thus improving overall network performance and security.

Staying within recommended EDL capacities also helps to avoid performance bottlenecks that can occur if too many dynamic lists are processed simultaneously. Therefore, consolidating EDLs is a best practice to maintain scalability and effectiveness in data center operations.
