Maintenance¶

This section covers maintenance, monitoring, and upgrades for the Wallarm Node — the main filtering component customers install in their own infrastructure. The Node powers API protection from Wallarm API Security and also runs passive vulnerability detection and Threat Replay Testing from Wallarm API Security Testing. Wallarm AI Hypervisor and Wallarm Infrastructure Discovery (both AWS-only) have their own maintenance flows and are not covered here.
