Defen.so

Defen.so is a security platform for developers that combines a managed web application firewall (WAF), vulnerability scanning, and uptime monitoring. The platform blocks SQL injection, cross-site scripting (XSS), and malicious bots, while automatically discovering API endpoints and applying rate limits. It integrates directly with development workflows and AI coding tools using Model Context Protocol (MCP) tools, CLI tools, and software development kits (SDKs). It also features automated repository and code scanning to detect exposed secrets, API keys, and vulnerable code structures. Additional features include active deception tools that serve fake data to attackers, domain and SSL certificate expiry alerts, and compliance logs exportable to CSV for SOC 2 and GDPR audits.
