Ask HN: What do you use to monitor website security (vulns, uptime, etc.)?

I recently built [PenZen](https://penzen.app). It scans websites for real vulnerabilities (not just SSL checks) using OWASP Zap under the hood and sends prioritized alerts with AI-powered remediation suggestions.

I made it because I was tired of tools that alert me about issues I don't understand or can’t do anything about. Curious: What are you using to monitor website security?

And more importantly: What actually makes you trust a report or take action on it?
