Alternative Notification Channels
Receive certificate expiry, availability, and change alerts through the channels your team already uses β Microsoft Teams, Slack, WhatsApp, PagerDuty, and more β in addition to or instead of email.
Full CLM Support for Let's Encrypt Certificates
Add-on support for automation to renew and deploy Let's Encrypt certificates directly from our site.
MSSQL deep TLS audit
Bring the full TLS hardening audit β protocol acceptance, cipher strength, forward secrecy, and more β to Microsoft SQL Server endpoints. Today MSSQL gets basic certificate monitoring (expiry, change detection, hostname match) but not the deep audit panel.
Distrusted CA detection
Warn when a certificate's issuer matches a CA that has been distrusted by major browsers or hit a publicly known incident.
Opt-In Certificate Industry News Emails
Stay informed about CA incidents, root certificate changes, and industry events that could affect your certificates β opt in to receive occasional advisory emails from the CertTracker team.
Monitor In-House Certificate Authorities
Track certificates issued by your own internal CA alongside public certificates β get the same expiry alerts, change detection, and inventory visibility for your private PKI.
Origin Certificate Monitoring (Behind CDN)
Monitor the certificate on your origin server directly, bypassing CDN edge nodes β so you can track both what your users see and what's running underneath.
Custom SNI Hostname Override
Specify a different hostname for the TLS handshake than the one being resolved β useful for staging environments, internal servers, and shared-IP hosts where DNS doesn't point where you need it.
RADIUS / EAP-PEAP certificate monitoring
Track the server certificate your RADIUS servers present to Wi-Fi and 802.1X clients β the cert that, when it expires, locks everyone out of the network.
iOS app
Native iOS app with push notifications for cert changes and expirations.
Azure certificate discovery
Connect your Azure tenant and automatically discover and monitor certificates across Key Vault, app registrations, and web services β no per-host setup.
Android app
Native Android app with push notifications for cert changes and expirations.
AWS certificate discovery
Bring the same automatic cloud discovery to AWS β ACM certificates, IAM server certificates, and ACM Private CA β via a read-only role.
CES/CEP enrollment (authenticated internal-CA issuance)
Issue from a Microsoft internal CA via Certificate Enrollment Web Services (CES/CEP) β fully authenticated automated enrollment, no single-use SCEP challenge password.
DNS-01 TXT Automation
Let CertTracker create and remove the _acme-challenge DNS record for you through your existing DNS provider, so renewal testing β and, later, renewals themselves β need no manual DNS edits.
Certificate Transparency presence
Cross-check certificates against Certificate Transparency logs to detect missing entries and β more usefully β unexpected ones.
RC4 cipher detection
Detect endpoints that still accept the long-broken RC4 cipher β including cases a standard scan can miss.
Choose your own theme
Pick the look that suits you β a bright light theme, the classic dark, or a warmer palette β right from the header. Your choice follows your account on every device.
Free website TLS check
Run a free, one-time SSL/TLS health check on any site you control β expiry, issuer, chain trust, protocols, ciphers, and hardening β right from our site, no account needed.
Free offline network scanner
Download a free Windows app that finds the certificates across your own network β entirely on your machine, nothing uploaded β so you can see what you have before you commit to anything.
Revocation status (OCSP)
Check each certificate's revocation status via OCSP and surface revoked or unknown results.
Chain validation & self-signed detection
Surface whether a certificate would validate against a normal browser trust store, separately from whether the handshake succeeded.
Proper Scanner GUI
A native desktop UI for the Network Discovery Scanner β paste your API token, type a CIDR, pick port profiles via checkboxes, watch live progress, click "Add selected" to create monitors. Same engine as the CLI today, friendlier shell.
Certificate inventory view (by certificate)
See your certificates listed one row per certificate β not per endpoint β with everywhere each one is deployed, so you can plan renewals and rotations at a glance.
Automated issuance & renewal DNS health
Verify the DNS records that let your certificates auto-issue and auto-renew are set up correctly β and alert you if they get changed or removed after the fact.
Expanded service coverage β mail, LDAP & database TLS
Monitor certificates on services that upgrade to TLS in-band (STARTTLS) rather than serving it on a dedicated port β starting with mail, directory, and database servers.
IP Range Scanning
Scan Range of IP for hidden Certs
Network Discovery Scanner
Sweep an IP range for TLS-bearing services and one-click add the new endpoints as monitors β the fastest way to onboard a network you didn't build.
Mobile-responsive web app
Full mobile layout for dashboard, monitor detail, and change history on viewports under 768px.
API access for integration to NMS Sytems
Allow monitor status and summary information via API calls to allow integration with customer in house or cloud NMS.
Key size & algorithm strength
Detect certificates using undersized or deprecated keys: RSA below 2048 bits, ECDSA below P-256, DSA at any size.
TLS session resumption support
Detect session-id and session-ticket resumption support. Purely informational metadata for performance-conscious admins.
Server cipher preference
Detect whether the server enforces its own cipher preference order. Important for ensuring strong ciphers actually get picked when modern clients connect.
CAA DNS record check
Confirm the monitored domain has a CAA record restricting which Certificate Authorities can issue for it. Closes a quiet mis-issuance vector.
TLS compliance profile rollup (PCI DSS 4.0 / NIST 800-52r2)
Single pass/fail per monitor against PCI DSS 4.0 and NIST 800-52r2 TLS requirements, derived from the granular checks. Particularly valuable for MSPs serving regulated clients.
HSTS header audit
Check for HTTP Strict Transport Security headers on HTTPS endpoints. Validates max-age length, includeSubDomains, and preload-list membership.
OCSP stapling check
Verify the server delivers a stapled OCSP response in the TLS handshake β faster certificate validation and better client privacy than client-side OCSP lookups.
Forward secrecy enforcement
Detect whether the server requires ephemeral-key ciphers (DHE/ECDHE). Without forward secrecy, past traffic can be decrypted if the long-term key is later compromised.
Monitor Intermediate Certificates
Detect when intermediate certificates in your chain are approaching expiry or have changed β not just the leaf certificate β so a bad chain rotation doesn't catch you off guard.
Cipher suite enumeration
List every cipher suite the server will accept, sorted by strength. Reveals weak ciphers still on the list even when stronger ones are preferred.
TLS protocol acceptance probe
Enumerate which TLS versions the server actually accepts β not just the one we negotiate. Surfaces deprecated protocols still enabled alongside modern ones.
Export All Account Records
Export all the account and logs for an account.
Account Data Purge
Purge all account data and replace with a confirmation date record
Excessive validity period detection
Flag certificates issued for longer than the 398-day maximum browsers enforce.
Hostname mismatch alerts
Email alert when a monitor's hostname stops matching the certificate's Subject CN or any SAN entry.
Weak signature algorithm detection
Flag certificates signed with SHA-1, MD5, or other broken signature algorithms.
Weak cipher & deprecated protocol alerts
Email alerts when a monitor negotiates a weak cipher or deprecated TLS version, on top of the existing in-app warnings.
Send Test Notification
Administrators can send a test email for any notification type β expiry warning, certificate change, availability alert, or recovery β directly from the Administration page, so you can verify delivery and formatting before a real event fires.
Custom Monitor Tags
Create and assign your own tags to monitors β group them by environment, team, application, or anything that makes sense for your organization β then filter the inventory by tag to focus on exactly the monitors you care about.
Certificate element change tracking or highlighting.
Highlight content or fields that have changed or been updated.
MSP Company Access
Companies can designate themselves as an MSP and then their customers can grant them access to manage their accounts.
Hostname / certificate CN mismatch detection
Flag monitors where the certificate's Common Name or SANs don't match the hostname being monitored.
Monitor Filter & Sort Bar
A filter bar above the monitor table lets you narrow the list by domain, polling interval, status, or availability, and sort by priority or days until certificate expiration β making it fast to find what you're looking for in large inventories.
Community wiki
A collaborative knowledge base where users can share configuration tips, integration guides, and troubleshooting solutions.
Reseller workflow improvements
Audit and polish the full reseller journey: referral visibility, commission tracking, and payout reporting.
Priority Reorder β Number Input Shifts Full List
Typing a priority number into the input field now correctly repositions that monitor and renumbers all affected rows, matching the behavior of drag-and-drop reorder.
Per-monitor alert frequency
Set different alert cadences per recipient on the same monitor β immediate for on-call, daily digest for managers.
Support ticket system
In-app ticket submission so customer issues are tracked and never lost in email.
Offsite database backups
Daily blob backups of both the primary and replica databases for point-in-time restore capability.
Feature request portal
