# Problem: cert renewals still cause outages because the “ticket → action” gap is real

SSL/TLS certificate expirations are still a classic SEV-1 trigger: monitoring fires, users report “connection not private,” and the service desk scrambles to find the owner, the right runbook, and the right place to deploy the renewed cert. A recent incident write-up shows how quickly this turns into multi-system thrash (renewal attempt, rate limits, CDN cache, nginx reload, etc.). ([devseatit.com](https://devseatit.com/incidents/?utm_source=openai))

The hard part isn’t _knowing_ what to do—AI can suggest “renew cert + deploy + purge CDN + reload.” The hard part is executing safely:

- AI is probabilistic and can hallucinate the wrong target, wrong environment, or wrong change window.
- Certificate deployment is a **change** with real blast radius.
- You need **deterministic execution** , approvals, and an audit trail.

This is where Autom Mate should sit: the execution + control layer between “insight” and “action,” orchestrating the exact steps across ITSM + infra + comms with governance.

* * *

# Proposed end-to-end workflow (Autom Mate as the execution layer)

## 1) Trigger

- **Trigger A (preferred):** Monitoring tool detects cert expiry within N days (or detects active expiry) and opens/updates an ITSM ticket.
- **Trigger B:** ServiceNow incident/change created with category = “Certificate” and CI = affected endpoint.

Autom Mate starts an Autom from the ticket/event trigger and pulls the ticket context (CI, environment, service owner, urgency). Autom Mate is designed to create/update incidents and orchestratelows across ITSM platforms.

## 2) Validation (context + policy checks)

Autom Mate performs deterministic checks before any action:

- Confirm the CI maps to a known cert object (CN/SANs, issuer, renewal method).
- Confirm environment (prod vs non-prod) and allowed change windows.
- Confirm ownership (service owner / app team) and escalation path.
- Confirm renewal path:
  - ACME/Let’s Encrypt vs internal PKI vs vendor-managed
  - If ACME: check for rate-limit risk and whether a fallback cert exists

Implementation notes:

- Use **Autom Mate library** actions where available for ITSM + messaging.
- Use **REST/HTTP/Webhook action** for internal PKI APIs, load balancer APIs, CDN purge endpoints, etc. Autom Mate supports REST-driven execution and backend vali run.

## 3) Approval (human or rule-based)

Because cert deployment is a change, require explicit approval unless it’s a pre-approved standard change:

- If “expires in \< 24h” or “already expired” → route to **Emergency/Expedited** approval path.
- Otherwise → normal change approval.

Approval experience:

- Send an approval card/message to the change authority in **Microsoft Teams**.
- Capture approver identity + timestamp back into the ITSM record.

Autom Mate supports orchestrating approvals through Teams/Slack and keeping workflows inside the existing governance mministic execution across systems

After approval, Autom Mate executes a fixed, versioned runbook:

- **Step 1:** Request/renew certificate
  - Internal PKI: REST call to issue/renew
  - ACME: call your ACME automation endpoint (or a controlled runner)

- **Step 2:** Deploy certificate to the right termination point
  - Load balancer / ingress / app gateway API (REST/HTTP/Webhook action)

- **Step 3:** Reload/restart where required (nginx/ingress reload)
- **Step 4:** Purge CDN / edge cache if applicable
- **Step 5:** Post-change validation
  - External HTTPS check
  - Confirm new expiry date and chain

- **Step 6:** Update ITSM
  - Add work notes with what was changed
  - Attach evidence (expiry before/after, endpoints touched)
  - Move incident/change to resolved/implemented

Autom Mate’s execution model distributes actions to library microservices, supports real-time monitoring, and records execution details—useful for auditability and post-incident review.

## 5) Loggifull chain:

- Trigger payload + ticket IDs
- Validation results (what was checked, what was blocked)
- Approval decision (who/when)
- Exact actions executed + responses
- Autom version executed (so you can prove which runbook version ran)

Autom Mate supports monitoring and execution traceability, including execution version tracking for stronger audit readiness.

## 6) Exception handling / rollbaodes and deterministic handling:

- Renewal fails (e.g., ACME rate limit) → switch to fallback cert path + require emergency approval if not pre-approved.
- Deploy succeeds but validation fails → rollback to last-known-good cert, reload, revalidate.
- CDN purge fails → retry with backoff; if still failing, notify on-call and keep ticket in “Mitigating.”

# Two mini examples

## Mini example 1: “Cert expires in 7 days” (planned)

- Trigger: daily check finds cert expiry \< 7 days.
- Autom Mate opens a **standard change** and posts a Teams approval to the service owner.
- After approval, Autom Mate renews via internal PKI API (REST/HTTP/Webhook action), deploys to the load balancer, validates, and closes the change with evidence.

## Mini example 2: “Cert already expired” (incident + emergency change)

- Trigger: monitoring + user reports create a P1 incident.
- Autom Mate enriches the incident with endpoint, current expiry, and likely remediation steps.
- Autom Mate requests ECAB approval in Teams, then executes: deploy fallback cert → reload → purge CDN → validate → update incident timeline.

This mirrors real-world incident patterns where expiry + cache + reload steps are often missed under pressure. ([devseatit.com](https://devseatit.com/incidents/?utm_source=openai))

# Why this needs governance (not just an AI agent)

- AI can _recommend_ “renew and deploy,” but it should not directly push certs to prod.
- Autom Mate provides the deterministic, approval-gated execution layer so actions are consistent, reviewable, and reversible.

# Questions for the community

1. For cert renewals, do you treat deployment as a **standard change** (pre-approved) or always require explicit approval for prod?
2. What’s your most common cert failure mode: ownership/visibility, renewal mechanism, deployment target confusion, or post-deploy validation gaps?
