An expiry date is the easy half of certificate monitoring. TrackSSL is built around the harder half: noticing when a certificate changes unexpectedly, when one is issued that you did not ask for, and when the certificate living on an internal host is about to lapse where no public scanner can see it.

Is TrackSSL worth it?
Yes, if certificate change is a thing you genuinely need to know about. Expiry monitoring is a solved problem available free in several places, so TrackSSL earns its price on the things around it — change detection, issuance monitoring and private certificates. Judged purely on expiry dates per pound, the ladder gets steep quickly: $17 a month for 20 domains is a lot next to free tiers that cover far more.
TrackSSL checks your certificates on a schedule and alerts on expiry, but its distinguishing work is noticing change. When certificate details are updated, when the infrastructure behind a domain shifts, or when a certificate is issued for your domain that you did not expect, it tells you.
That last one matters more than it sounds. An unexpected certificate for your domain can mean a misconfiguration, or it can mean somebody is impersonating you, and neither shows up in an expiry date.
It also handles certificates that public scanners cannot reach. Internal hosts, private networks and self-signed certificates are explicitly supported, which rules out most of the free competition on its own.
The parts of certificate monitoring that are not just a countdown.
Alerts when certificate details or the infrastructure behind them change, not only when a date approaches. A certificate that was silently replaced is worth knowing about.
Flags certificates issued for your domains that you were not expecting, which is a security signal rather than an operational one.
Monitoring for hosts that are not publicly reachable, plus self-signed certificates. Available on the Growth tier and above.
Email, Slack, Microsoft Teams, SMS and webhooks, with Slack included even on the free tier.
Programmatic access from $35 a month, which matters if certificates are managed by tooling rather than by people.
Two certificates free forever with Slack alerts. Small, but enough to try the product properly.
Five paid tiers, priced per domain, with a month free on annual billing.
| Plan | Price (annual) | Domains | Notes |
|---|---|---|---|
| Free | $0 | 2 | 1 user, expiry and change monitoring, Slack |
| Starter | $17/mo | 20 | $19 billed monthly. Teams and webhook integrations |
| Growth | $35/mo | 80 | 2 users, API access, private certificate monitoring |
| Complete | $72/mo | 200 | 3 users |
| Scale | $136/mo | 500 | 5 users |
Monitoring vendors change plan limits and prices frequently and without announcement. Every figure here carries a "verify on their site" caveat and you should take it seriously before making a decision on cost.
TrackSSL does two things we do not do at all. It monitors internal and self-signed certificates, where we can only see what is reachable over public HTTPS; and it watches for unexpected certificate issuance, which is a security function we have never claimed. If either of those is the reason you are shopping, we are not a substitute and the rest of this section will not change that.
Where we compare well is scope and price. Our Starter plan is $5 a month for 25 monitors, and a monitor can be a certificate, an uptime check, a domain expiry watch, a page change watch or a cron heartbeat. Their Starter is $17 a month for 20 certificates and nothing else. Our expiry window is configurable from 1 to 60 days, and we alert both when a certificate has already expired and when the check itself fails.
The honest split: certificate security, internal hosts, issuance monitoring — theirs. One bill covering certificates alongside everything else that can take a site down — ours.
Every recorded change is compared word by word and kept with a before-and-after image. This is the real output, shown with worked example data.
Price fell from $49 to $39, and an annual discount was added.
The item is available again and the basket button returned.
A new subprocessor was added in another jurisdiction.
The free plan sends to one email address. Every paid plan adds the chat and webhook channels below, with 2 to 10 destinations depending on the plan. However many alerts you receive, the price does not change — nothing here is metered or charged per alert.
There are no voice calls and no SMS. If a phone call at 3am is a hard requirement, say so before you subscribe — we would rather tell you now than refund you later.
There is a free tier covering 2 certificates with Slack alerts and no expiry date on the plan itself. Paid plans start at $17 a month billed annually for 20 domains. Verify current pricing on their site.
Updates to certificate details and changes in the infrastructure behind a domain. A certificate that was replaced without anyone mentioning it is exactly the kind of thing an expiry-only checker will never surface.
Yes, including private networks and self-signed certificates. That capability sits on the Growth plan at $35 a month and above.
Yes, from the Growth tier at $35 a month. The $17 Starter tier does not include it.
No. It is a dedicated certificate tool and does not check whether your site is actually up.
One on Free and Starter, two on Growth, three on Complete and five on Scale. Worth checking against your team size before committing.
No, and it does not try to be. Red Sift Certificates Lite covers 250 certificates for nothing. TrackSSL is priced for change and issuance monitoring and internal certificate support, which free tools do not provide.
For internal certificates and issuance monitoring, theirs — we do neither. For covering certificates alongside uptime, domains, page changes and heartbeats on one $5 plan, ours.
