One expired cert becomes a support ticket

Across dozens of client environments, a single missed certificate or domain renewal turns into an outage, a ticket, and an awkward call. SSLCanary watches them all from one place and routes alerts into the channels your team already lives in.

Is it OK right now?

Plain status: valid, expiring, expired, or not secure — no jargon.

SSL and domain, together

Common questions

Can I keep each client's domains separate?
Yes. Group domains by client and, where you want, give a client a read-only login scoped to just their group — clean multi-tenant separation.
Where do the alerts go?
Wherever your team works: email, Slack, Microsoft Teams, Discord, Telegram, or a generic webhook into your own tooling. Every alert is logged with its delivery status.
Does it watch domain expiry as well as SSL?
Yes — SSL certificate expiry and domain-name renewal are both first-class, so neither slips through on a client site.
Will it scale to all our clients?
Yes. Start free with 5 domains and scale to 25, 100, 500, or 1000 across every client, with bulk import to onboard them fast.
Do we install an agent on client machines?
No. Checks run from the outside over the public internet — nothing to deploy or maintain on client infrastructure.

Add your sites, choose your alerts, and let SSLCanary watch every certificate and domain for you.
