According to dynamic updates best practices, what is the recommended threshold value for content updates...

For a mission-critical network, it is recommended to configure the content update threshold to 8 hours. This ensures that the network is protected with the latest threat intelligence, updates to signatures, and other critical content, minimizing the exposure to newly discovered vulnerabilities and threats.

Regular content updates are crucial in mission-critical environments to ensure the firewall is up-to-date with the latest protections. 8 hours is considered an optimal balance between timely updates and network performance.
