Security Intelligence

💡 SQL Injection Campaigns

SQL injection remains one of the most common web attack vectors. Attackers inject malicious SQL code through input fields to extract database contents, modify data, or gain administrative access. Automated scanners test for SQLi vulnerabilities at massive scale.

💡 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.
