Security Intelligence

💡 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.

💡 Vulnerability Scanning Explained

Vulnerability scanning is the automated process of probing web applications for known weaknesses. Attackers use tools like Nuclei, Nikto, and ZAP to test thousands of hosts per hour, looking for exposed configuration files, outdated software, and default credentials.
