The integration between Trust Lifecycle Manager (TLM) and Imperva Web Application Firewall (WAF) enables organizations to centrally govern the full certificate lifecycle—issuance, renewal, and revocation—via TLM, and then automatically deploy the certificates to web applications secured by Imperva WAF for continuous, compliant TLS protection.
