TLS and SSL Certificate Monitoring — Continuous Visibility Across Every Endpoint
CertControl automatically scans all your TLS and SSL certificates — internet-facing and internal — and alerts you before problems occur. Not once. Continuously.

Full TLS visibility — not just expiry dates
Most teams know when a certificate expires. Fewer know whether the chain is valid, whether OCSP validation works, or whether the server still offers deprecated TLS 1.0. CertControl covers all of it.
Expiry dates and renewal windows
Automatic tracking of all certificate expiry with configurable alerts at 60, 30, 14, 7 and 1 day. With 47-day certificates arriving in 2029, this is critical infrastructure.
Certificate chain and OCSP
Full chain validation from leaf to root. OCSP status checks that detect revoked certificates before they cause browser warnings or connection failures.
TLS protocols and cipher suites
Detection of deprecated protocols (TLS 1.0/1.1, SSLv3) and weak cipher suites. A+ to F grading per endpoint — like Qualys SSL Labs but automated and continuous.
SAN validation and domain coverage
Verification that a certificate's Subject Alternative Names actually cover the domains they are supposed to — including wildcard expansion and potential gaps.
Certificate Transparency logs
Monitoring CT logs to detect certificates issued to your domains that you do not know about. Critical for detecting unauthorised issuances and shadow IT.
Internal networks via on-premise agent
The CertControl agent scans internal endpoints behind your firewall and sends results securely to the platform. Complete visibility — no exceptions for internal systems.
Most outages start internally
Internet-facing certificates are visible. Internal certificates — on AD, intranets, mail servers, CI/CD pipelines, and internal API communication — are the ones that most often surprise teams, because nobody knew they existed.
Internet-facing scanning
- Direct scanning from the CertControl platform
- Full TLS protocol analysis and grading
- HTTP headers (HSTS, CSP, X-Frame-Options)
- Automatic subdomain discovery via CT logs
- Supplier certificates on your domains
Internal network scanning (agent)
- On-premise agent deployed in your network
- Outbound connections only — no inbound required
- Works behind firewalls and NAT
- Same certificate data as internet-facing scanning
- Unified view in the CertControl platform
Alerts that actually reach the right people
An alert sent to a shared inbox is the same as no alert. CertControl sends to specific recipients, on the channels they use, with enough context to act immediately.
Configurable thresholds
Set alerts at exactly the right points for your renewal process — 60, 30, 14, 7, and 1 day before expiry. Separate thresholds for critical systems.
Email and webhooks
Notifications via email to named recipients and webhooks to Slack, Microsoft Teams, PagerDuty, or any system accepting HTTP POST.
Escalation and backup recipients
Configure escalation rules so critical certificates never depend on a single person. Backup recipients activate automatically when needed.
Frequently asked questions
What is TLS certificate monitoring?
TLS certificate monitoring is continuous automated scanning of your endpoints to detect certificate expiry, weak cipher suites, chain errors, and other TLS issues — before they cause outages or security gaps.
What is the difference between TLS and SSL monitoring?
SSL is the predecessor to TLS. Today all SSL certificates are in practice TLS certificates. TLS/SSL monitoring covers both terms — the certificates that secure HTTPS connections.
Can CertControl monitor internal systems behind a firewall?
Yes. The CertControl agent is deployed in your network and scans internal endpoints. The agent communicates outbound only to the CertControl platform — no inbound ports need to be opened.
What does TLS grading mean?
TLS grading assigns each endpoint a letter grade from A+ to F based on protocol versions, cipher suites, chain health, and security headers. CertControl grades every endpoint automatically and continuously — flagging anything below a B as a finding.
Does CertControl support ACME/automated renewal?
Yes. CertControl integrates with the ACME protocol (Let's Encrypt and other CAs) and can fully automate certificate renewal — so you never need to react to an expiry alert again.
