Platform · Certificate Discovery

Find every certificate, everywhere it lives.

MachineCert discovers certificates across the public internet, every cloud, and your internal network — then unifies them into one risk-scored inventory in under 60 seconds.

The problem

You can’t secure
what you can’t see.

Organizations lose visibility because certificates are spread across dozens of systems, clouds, teams, and environments. Discovery has to be continuous, complete, and automatic.

Unknown certificates

You can’t protect what you can’t see. Shadow and forgotten certs expire without warning.

Spreadsheets fall behind

Manual tracking can’t keep up with 8× the renewal cadence of the 47-day era.

Multi-cloud sprawl

Certs live across AWS, Azure, GCP, Kubernetes, and on-prem with no single view.

Single-CA blind spots

CA portals only show their own certs — not the ones issued everywhere else.

How it works

From zero to a complete
inventory in 60 seconds.

1
Connect

Add cloud accounts and CAs, or drop the agent on your network. Read-only, minutes to set up.

2
Discover

CT logs, DNS, active scans, cloud connectors, and agents find every certificate continuously.

3
Unify

Deduplicated into one inventory, enriched with owner, chain, crypto, and exposure.

4
Score & act

Each cert is risk-scored and routed to monitoring and automated renewal.

Outcomes

Visibility that prevents
the outage.

Complete visibility

Public, cloud, and internal — nothing hides.

Prevent outages

Catch expirations weeks before they break production.

Risk-scored from day one

Every cert ranked by exposure, crypto, and expiry.

Find shadow PKI

Surface unowned and rogue issuance automatically.

47-day ready

Continuous discovery keeps pace with short lifetimes.

No keys leave your network

Metadata only; the agent never exfiltrates secrets.

FAQ

Certificate discovery,
answered.

For public and cloud-facing certificates, MachineCert reads Certificate Transparency logs, performs DNS resolution and active TLS scans, and connects read-only to cloud provider APIs. No agent is required to inventory anything reachable from the internet or your cloud accounts.
A lightweight agent runs inside your network and reads certificate metadata from servers, Active Directory Certificate Services, Kubernetes, HashiCorp Vault, keystores, and the Windows certificate store. It reports metadata only — private keys never leave your environment.
A first inventory typically completes in under 60 seconds for public and cloud sources. Internal agent scans complete within minutes depending on network size, then run continuously.
AWS, Azure, and Google Cloud certificate stores, plus CAs and tools including DigiCert, Sectigo, Let’s Encrypt, ZeroSSL, HashiCorp Vault, and Kubernetes cert-manager — 12 native sources today.
Yes. By correlating CT log issuance against your known inventory, MachineCert surfaces certificates issued for your domains that nobody registered — including shadow PKI and potential mis-issuance.
Discovery collects certificate metadata: subject, issuer, validity, key type, chain, and host. It does not collect or transmit private keys.
Cloud connectors sync on a schedule, CT log monitoring is real-time, and the agent scans continuously — so new and rotated certificates appear in the inventory automatically.
Shorter lifetimes mean roughly 8× more renewals. Continuous, complete discovery is the foundation — you can’t automate renewal for certificates you don’t know exist.
