Platform · ACME Automation

Standards-based certificate automation.

By Updated

MachineCert speaks ACME natively — ACME v2 with DNS-01 and HTTP-01 challenges — to request, validate, issue, and deploy certificates from Let’s Encrypt, ZeroSSL, and any ACME-capable CA, fully hands-off.

The problem

ACME is powerful —
and easy to get wrong.

The ACME protocol enables automation, but stitching it together yourself across providers and challenge types is brittle work that fails quietly.

Hand-rolled ACME

Home-grown ACME clients and cron jobs break and drift over time.

DNS validation pain

DNS-01 across many providers is fiddly and error-prone by hand.

Many CAs, many flows

Each CA and tool has its own quirks to manage separately.

Silent failures

A failed challenge often goes unnoticed until the cert expires.

How it works

Order, validate,
issue, deploy.

1
Order

MachineCert places the ACME order with the chosen CA.

2
Validate

Completes DNS-01 or HTTP-01 challenges automatically.

3
Issue

The CA issues the certificate once validation passes.

4
Deploy

The new cert is installed and the service reloaded.

Outcomes

ACME done right,
at scale.

Native ACME v2

Full protocol support, not a fragile wrapper.

DNS-01 everywhere

Automated TXT challenges across DNS providers.

HTTP-01 ready

Well-known path validation when DNS isn’t an option.

Any ACME CA

Let’s Encrypt, ZeroSSL, and private ACME.

Robust retries

Failures are retried and surfaced, never silent.

Fully hands-off

Issuance and renewal without human steps.

FAQ

ACME automation,
answered.

ACME (Automated Certificate Management Environment) is an open standard protocol for automating certificate issuance and renewal. It lets software request, validate, and obtain certificates from a CA without manual steps — it’s what powers Let’s Encrypt.
They are two ways to prove domain control. DNS-01 places a TXT record in your DNS; HTTP-01 serves a token at a well-known path on your web server. DNS-01 works for wildcards and internal hosts; HTTP-01 is simple for public web servers.
Any ACME-compatible CA, including Let’s Encrypt and ZeroSSL, as well as private and enterprise ACME endpoints — alongside non-ACME CAs like DigiCert through direct integrations.
No. MachineCert provides native ACME automation, so you don’t have to build, run, or maintain your own ACME client or cron jobs.
It automates the creation and cleanup of the required TXT records across supported DNS providers, then completes validation — no manual record editing.
MachineCert retries with backoff, keeps any existing valid certificate in place, and alerts the owner with context, so a failed challenge never results in a silent expiry.
Yes. Wildcard certificates require DNS-01 validation, which MachineCert automates, so wildcard issuance and renewal are fully hands-off.
ACME automation is the issuance engine behind renewal: when a certificate approaches expiry, MachineCert re-runs the ACME flow and deploys the new certificate automatically.
