Security Intelligence
💡 API Abuse and Enumeration
Modern attacks increasingly target APIs rather than traditional web interfaces. Attackers enumerate endpoints, test for broken authentication, and exploit excessive data exposure. API attacks are harder to detect as they mimic legitimate programmatic access patterns.
💡 TLS Certificate Misconfigurations
Expired, self-signed, or misconfigured TLS certificates create security vulnerabilities and trust issues. Certificate monitoring, automated renewal through ACME protocols, and proper certificate chain configuration prevent both security gaps and service disruptions.
