SSL/TLS Certificate Monitoring
Topscan delivers TLS certificate monitoring, certificate health monitoring, and automatic certificate discovery across your domains and subdomains.

Challenges & Solutions
Certificate expiration monitoring catches failures early, supports downtime prevention, and stops issues before they reach users.
Challenges
- Certificates expire on domains you forgot you had
- Calendar certificate renewal reminders get missed or skipped entirely
- A valid certificate can still be misconfigured
- New cloud resources never make it onto the monitoring list
- Sharing certificate status requires handing out platform access
Solutions
- Topscan uses automatic certificate discovery across all subdomains via Asset Discovery
- Certificate expiry alerts at 30, 14, and 7 days - delivered through email notifications or Slack
- Health checks cover weak cipher suites, outdated TLS version issues, and untrusted certificate chain problems
- Cloud-connected accounts are included automatically - no manual registration needed
- Share the centralized certificate dashboard with your team or auditors without granting platform access (coming soon)

Step 1. Automatic Certificate Discovery
Topscan scans every domain and subdomain in your external perimeter - including assets added recently or connected through cloud accounts. No spreadsheet. No manual entry.
- Discovers certificates through automatic certificate discovery without a curated list
- Covers cloud-connected accounts automatically
- New subdomains enter SSL certificate monitoring without any additional action from your team

Step 2. Expiration and Health Tracking
Each discovered certificate is tracked by certificate expiration date and certificate health monitoring - not just when it runs out, but whether it's safe right now.
- Certificate expiration date tracked with staged advance alerts
- Checks for weak cipher suites and deprecated TLS version issues (1.0, 1.1)
- Detects mismatched or untrusted certificate chain issues and self-signed certificates in production
- Maintains SSL certificate tracking for active and newly discovered assets

Step 3. Configurable Alerts Before Expiration
Alerts go out early enough to support renewal before expiration - not in a fire-drill at midnight. Set configurable warning windows and let the platform handle the rest.
- Warning thresholds at 30, 14, and 7 days - or all three simultaneously
- Delivered to Slack, email, or your team's preferred channel
- No need to log in and check manually

Step 4. Centralized Certificate Dashboard
Every certificate in one view: status, expiration date, health signal. Filter by domain, date, or configuration state. Sharing with your team or an auditor without giving them full platform access is coming soon.
- Status labels: valid, expiring soon, expired
- Filters by domain, expiration date, and health status
- Centralized certificate dashboard sharing without full account access (coming soon) - practical for audits and team reporting
Features & Capabilities
Automatic Certificate Discovery
Finds SSL/TLS certificates across all subdomains and cloud-connected assets - no manual list required.
Expiry Alerts with Configurable Warning Windows
Staged alerts at 30, 14, and 7 days before a certificate expires - tuned to your certificate renewal workflow.
Certificate Health Checks
Detects weak cipher suites, deprecated TLS version issues, mismatched chains, and self-signed certificates in production.
Full External Footprint Coverage
Monitoring extends to every subdomain from Asset Discovery and every cloud account connected to the platform.
Centralized Certificate Dashboard
One view for all certificate statuses - valid, expiring soon, expired - with filters and auditor-safe sharing (coming soon).
No Manual Registration Required
Newly added domains and subdomains enter monitoring automatically. Coverage keeps pace with your infrastructure and monitors SSL certificates.
Who Topscan is Built For
DevOps and Infrastructure Teams
Uptime for production services is your responsibility. Topscan tracks every certificate across your external perimeter - including ones added after your last manual audit. Alerts arrive before expiration, not during an incident.
CTOs and Engineering Managers at Growing Companies
Hiring a dedicated security engineer isn't always the right move at your stage. Topscan delivers certificate visibility and control without adding headcount - so an expired certificate doesn't become a leadership conversation you weren't prepared for.
Teams Preparing for SOC 2 or ISO 27001
Certificate health is part of what auditors look for. Topscan collects that evidence as a natural output of daily monitoring - no separate report to prepare when the audit window opens.
Teams Using Let's Encrypt or Automated Issuance
Automated issuance is a solid starting point. But it doesn't confirm that certificate renewal ran correctly, that new subdomains are covered, or that the certificate authority chain is valid. Topscan monitors the actual state - not just whether issuance is configured.

About Topscan
Topscan gives DevOps and engineering teams continuous visibility into their external attack surface - without the overhead of enterprise security tooling.
SSL & TLS certificate monitoring is one layer of a broader security platform that covers domains, subdomains, cloud assets, and infrastructure endpoints in a single view.
