Hardenize moved to $5K+/year enterprise. Here's the self-serve alternative.

Hardenize, a popular web security posture monitoring tool, moved to enterprise-only pricing ($5K+/year) after being acquired by Red Sift, eliminating its self-serve tier. Guardr positions itself as a self-serve alternative covering the same monitoring surface—security headers, TLS/SSL certificates, DNS security, cookie attributes, and exposure path detection—plus uptime monitoring and platform-specific fix instructions. It offers a free URL scanner with letter grading and continuous monitoring for agencies and developers.
