Security Intelligence

💡 HTTP Header Analysis for Threat Detection

Examining HTTP headers beyond User-Agent reveals attack tools and automated scripts. Missing standard headers, unusual ordering, non-standard values, and inconsistencies with claimed client identity all serve as reliable detection signals.

💡 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.
