# REL AI: Remediation Execution Layer > Autonomous, human-authorized containment and remediation. REL micro-segments the network around a threat, applies the fix, validates it, and rolls back automatically if it fails. Every action is reversible and recorded in a tamper-evident audit log. REL AI is an ElasticD3M, LLC Agent-as-a-Service product. It deploys into the customer's environment under the customer's authorization model and kill switch, in United States regions. ## What it does 1. Contain: micro-segment the network around a threat and isolate affected systems. 2. Remediate: apply the approved fix (patch, configuration, access control, encryption, policy). 3. Validate: confirm the remediation held. 4. Reverse: automatic rollback to prior state on any failed remediation (zero-fail design target). Every action is write-ahead logged with cryptographic chain of custody. ## Control model - The customer authorizes every action that changes their environment; nothing runs without sign-off, and the customer holds a hard stop (kill switch). - Pairs with Eject AI™, which forensically removes the contained artifact and confirms the attack vector is closed. ## Engagement REL is deployed, not self-serve. To engage: hello@ai4rel.ai. Onboarding configures your authorization model and kill switch before any action runs. ## Notes Human-in-the-loop on every environment-changing action. All operations in United States regions.
