Add a domain and Acumen Logs pulls the certificate straight away: issuer, expiry date, and chain. Then it keeps checking, and tells you 30, 14, and 7 days before anything runs out, or the moment a certificate stops being trusted.
No credit card. Set up in under 60 seconds.
No OpenSSL commands and no spreadsheet of renewal dates. Paste a domain and the certificate details appear in seconds.
A main domain, a subdomain, a wildcard, or an API endpoint. The certificate is read immediately.
Alerts go out 30, 14, and 7 days before expiry. That is enough time to renew without a rush.
Email on every plan. Slack, Microsoft Teams, desktop, and webhooks from the $5 Solo plan.
Issuer, expiry date, and chain show up as soon as you add the domain.
Browsers do not only check the date. Acumen Logs validates the whole certificate, so you find out about a trust problem before a customer sees a full-page warning.
The certificate is valid until next year.
It was issued for www.northline.example, not shop.northline.example. Browsers block the mismatch.
The padlock shows on your laptop.
The server is missing an intermediate certificate, so some phones and older browsers refuse the connection.
A partner’s API answers over HTTPS.
The certificate is self-signed. Your integration fails the moment it validates properly.
Nothing has changed on your side.
The certificate authority revoked the certificate. Every visitor now sees a security warning.
Every endpoint shows the details you would otherwise dig out by hand. Clear, readable, and always current.
Expires in 12 days. The 14-day reminder went to #ops on 20 Oct.
Hosting reminders often fail silently, or go to someone who left last year. Acumen Logs sends renewals to the channels your team actually reads.
shop.northline.example expires on 3 Nov 2026. Issuer: Let’s Encrypt R11.
Ten domains or thousands of subdomains, they all sit on one dashboard. No more tracking renewals in a spreadsheet.
Check the certificate your users actually receive, wherever it terminates.
Watch *.yourdomain and the subdomains that depend on it.
Custom endpoints and partner APIs, not just the website.
Certificates managed by an agency, a host, or a vendor you rely on.
SSL checks share an allowance with uptime and WHOIS checks. No credit card to start.
Need more checks or longer history? Essentials and Pro are on the pricing page.
See every plan →SSL is one of the quiet things that take sites down. The same dashboard watches the others.
Know before a domain lapses, or its registrar or name servers change.
Check that the site responds, every minute, from multiple regions.
Keep customers informed with a page that updates itself.
Check any certificate right now, without an account.

“Love the support we got from Acumen Logs! Highly recommended.”
30, 14, and 7 days before it expires, so there is time to renew without a scramble.
Self-signed certificates, revoked certificates, certificates issued for the wrong domain, and missing intermediate certificates in the chain.
