Certificate automation
Set it up once. Never chase a renewal again.
Certificate automation issues, renews, deploys, and verifies your SSL certificates without
manual steps, so a certificate never expires because someone forgot. You point one DNS
record at CertKit, and the whole cycle runs on its own from then on.

The manual way doesn't scale
Managing certificates by hand is a standing chore: a spreadsheet of expiry dates, calendar
reminders, an OpenSSL command you look up every time, and a renewal job on each server that
someone has to babysit. It works until it doesn't, usually at 2am, usually while the person
who set it up is on vacation.
It gets harder every year. The 200-day maximum is already in effect, and 47-day
certificates are coming by 2029. A renewal that used to happen once a year will happen
roughly eight times a year, on every certificate, on every server. At that cadence, manual
renewal stops being a process and becomes a liability.

How certificate automation works
CertKit acts as a central ACME
client for all your domains. You add your domains and point one
delegated DNS CNAME record at CertKit. After
that, CertKit requests and renews every certificate on its own, and the CertKit Agent
deploys each one to your servers and appliances and confirms it is being served.
That one record is everything required to automate SSL certificate renewal across your fleet.

Set it up once. CertKit issues, deploys, monitors, and renews on schedule, with no human in the loop.
No scripts. No cron jobs. No ACME client to install on each box. No 2am alerts when
something expires.
Works with your certificate authority
CertKit automates issuance and renewal from the public CAs teams use most. Move to a free CA
like Let's Encrypt or Google Trust Services once renewal is automated, or stay with the
commercial CA you already have. You are never locked in.

Automation is one stage of the lifecycle
Certificate renewal automation is the stage that removes the most work, but it is one part of
certificate lifecycle management. CertKit
also discovers the certificates you forgot about and
monitors every one, so nothing slips through, and
it deploys to your servers and appliances automatically.

Frequently asked questions
Do I have to run an ACME client or script on each server?
No. CertKit issues and renews every certificate centrally. The CertKit Agent then deploys
each one to your servers and appliances, so there is no ACME client, renewal script, or
cron job to maintain on each box.
Why servers shouldn't need ACME
Can I automate the certificates I already have?
Yes. You reissue them through CertKit for the same domains. That is free and does not
invalidate your current certificates, so they keep working until you switch over. From
then on, CertKit renews and deploys them automatically.
What happens if an automated renewal fails?
CertKit monitors every certificate and alerts you before an expiry becomes an outage, so a
failed renewal is something you hear about early, not after a site goes down.
About certificate monitoring
Do I have to switch certificate authorities?
No. CertKit works with Let's Encrypt, your current CA, or any ACME-compatible authority.
Most teams move to free Let's Encrypt certificates once renewal is automated, but you
don't have to.
