Certificate and TLS monitoring for every internet-facing service.
Certificates are both a security control and a discovery signal. An expired certificate can create an outage; an unexpected certificate can expose a forgotten deployment or an impersonation attempt. TUT1 helps teams monitor certificate posture across authorized external assets.
1.Keep certificate problems visible
Review certificate validity, expiry, hostname coverage, trust-chain issues, weak keys and legacy protocol support. Use discovered certificates to identify previously unknown hosts and subdomains.
2.Improve web posture with evidence
Combine TLS findings with HTTP security headers, exposed services and hostname data. The result is a clearer picture of which public services need a configuration fix and why.
3.Monitor change, not just expiry
New or changed certificates can reveal new infrastructure, configuration drift or impersonation risk. Continuous monitoring makes that change visible to the team responsible for the domain.
•Frequently asked questions
- Does TLS monitoring replace certificate management?
- No. It provides external validation and complements internal certificate lifecycle management.
- Can a valid certificate still be risky?
- Yes. Validity does not prove correct ownership, configuration or business purpose.
- What should we do about an unexpected certificate?
- Confirm ownership, inspect the associated host and domain, then investigate or remediate according to policy.
