Solutions · Prevent Outages

Know before certificates become outages.

By Updated

Expired certificates are one of the most common, most preventable causes of downtime. MachineCert catches them weeks early, maps the blast radius, and renews before anything breaks.

Why outages happen

Most certificate outages
are preventable.

They almost always trace back to a cert nobody saw, nobody owned, or nobody renewed in time. Each gap is solvable.

Unknown certificates

You can’t renew a cert you never knew existed — until it expires.

Missed renewals

A reminder slips, an owner leaves, and the window quietly closes.

Shared-cert fan-out

One expired certificate can take down many services at once.

No clear owner

When it breaks, the first half hour is spent finding who’s responsible.

The early-warning system

Catch it weeks before
it breaks.

1
Detect early

Monitor every cert and flag expiry weeks in advance.

2
Map impact

See exactly what breaks if it expires, via the Trust Graph.

3
Route to owner

Notify the right team and on-call automatically.

4
Auto-renew

Renew and deploy before the window ever closes.

Escalation flow

Escalation before expiration.

FAQ

Outage prevention,
answered.

Almost always because a certificate expired unexpectedly — it wasn’t discovered, wasn’t monitored, had no clear owner, or its renewal was missed. The certificate itself works fine until the moment it expires, then dependent services fail.
It discovers every certificate, monitors expiry continuously, maps the blast radius of each one, routes alerts to the right owner well before the deadline, and — where enabled — renews and deploys automatically so the certificate never expires.
MachineCert flags upcoming expirations weeks in advance and escalates as the deadline approaches, so there’s ample time to act before anything is urgent.
It’s knowing exactly which applications, services, and load balancers depend on a certificate. If a cert is about to expire, you immediately see everything that would go down — and prioritize accordingly.
Ownership is derived from tags, accounts, namespaces, and directory data, then mapped to teams and on-call rotations — so alerts always reach someone accountable.
Yes — Slack, Microsoft Teams, email, PagerDuty, Opsgenie, ServiceNow, Jira, and webhooks, so warnings land where your team already works.
MachineCert detects high-fan-out certificates — those presented by many services — and prioritizes them, since their expiry would cause the widest outage.
Automation is the strongest protection, but even monitoring, ownership, and early alerts dramatically reduce outage risk. MachineCert supports both monitored and fully automated renewal.
