Platform · Renewal Automation

Automate renewals before they become outages.

By Updated

MachineCert renews ahead of expiry through ACME and every major CA, deploys to the endpoint, and verifies it’s live — with zero downtime and full blast-radius awareness.

The problem

Renewal is where
certificates fail.

Discovery and monitoring tell you what’s coming. Only automation makes sure the renewal actually happens — every time, on time.

Manual renewals don’t scale

Calendar reminders and runbooks break the moment volume spikes.

47-day cadence

Shorter lifetimes mean ~8× more renewals — humans can’t keep up.

A miss is an outage

One forgotten renewal becomes a P1 and an emergency page.

Scripts rot

Home-grown automation drifts out of sync as infrastructure changes.

How it works

Detect, renew, deploy, verify.

1
Detect

Monitoring flags certs approaching expiry and queues them.

2
Renew

Re-issue via ACME or the right CA, automatically.

3
Deploy

Push the new cert to the endpoint and reload gracefully.

4
Verify

Confirm the new cert is live before retiring the old one.

Architecture

A closed renewal loop.

Hands-off renewal

Certificates renew themselves, end to end.

Zero downtime

Deploy and verify before retiring the old cert.

Any CA, any protocol

ACME, ACM, Key Vault, DigiCert, private CAs.

Blast-radius safe

Renew knowing the downstream impact.

47-day ready

Automation scales with shrinking lifetimes.

Alerts only on exceptions

You hear about it only if something needs you.

FAQ

Renewal automation,
answered.

It’s the process of renewing certificates without human intervention — detecting upcoming expiry, re-issuing through a CA or ACME, deploying the new certificate to the endpoint, and verifying it’s live, all automatically.
It deploys the new certificate alongside the old one, reloads the service gracefully, and verifies the new cert is serving before retiring the previous one — so there’s never a gap.
ACME (DNS-01 and HTTP-01), AWS ACM, Azure Key Vault, and CAs including DigiCert, Sectigo, Let’s Encrypt, ZeroSSL, and private/internal CAs.
To AWS ACM, Azure Key Vault, Kubernetes secrets, NGINX, Apache, IIS, F5, and load balancers — then it reloads or hot-swaps the service as needed.
Yes. Through the Machine Trust Graph, MachineCert knows what depends on each certificate, so it can sequence renewals safely and verify dependents stay healthy.
MachineCert retries, keeps the existing valid certificate in place, and alerts the owner with full context — there’s no silent failure or surprise outage.
You’re alerted on exceptions — a failed renewal or a cert that needs human input — rather than for every routine renewal.
Roughly 8× more renewals per year is unmanageable manually. Full automation makes the increased cadence a non-event.
