HerdSecurity

HerdSecurity watches every file on a customer's web server and raises an alert as soon as something is added, changed or deleted. Its optional File Lock puts tampered files straight back, which stops malware injections and backdoors before they do damage. It works on shared hosting, VPS, Docker and WordPress.

Highlights

• Four agent types: single PHP file, Docker, SSH daemon and WordPress plugin
• Scan results encrypted end to end with RSA-2048 and AES-256-GCM
• File Lock auto-revert, with a framework-aware mode for CMS updates
• Side-by-side diff viewer and heartbeat alerts when an agent goes quiet
• Free forever plan for an individual site
