After an AI-built prototype goes live, monitor five things: newly disclosed vulnerabilities in its dependencies, authentication failures, unusual error rates, use of its keys and tokens, and any drift between what is deployed and what was reviewed. Launch is not the end of the review, because the world keeps changing around fixed code.
Why launch day is not the finish line
A package that was clean on Friday can have an advisory on Tuesday. A prototype that nobody expected to be popular can attract attackers who probe for common mistakes. Monitoring turns surprises into alerts you can act on.
The five signals
1. New vulnerabilities in dependencies. Your code did not change, but the facts about it did. Rescan on a schedule and whenever a major advisory appears, and subscribe the owner to alerts. GitHub's Dependabot alerts are one example of a source that tells you when a dependency has a known vulnerability.
2. Authentication failures. A burst of failed logins or token errors can mean guessing or a broken client. Log failures without recording the secrets used.
3. Error rates and odd requests. Spikes in server errors, requests for paths that do not exist and unusual input sizes often show up before a real incident.
4. Key and token use. Watch your provider dashboards for usage from unexpected places or at unusual volume. A leaked key often shows up first as a bill.
5. Drift. Confirm that what runs in production matches the reviewed commit. Unexplained differences mean someone changed something outside the process.
Make alerts reach a person
An alert that nobody reads is decoration. Send each signal to the named owner, set a response time you can keep, and write a short runbook: what to check first, how to disable the feature, who to call.
| Signal | Alert goes to | First action |
|---|---|---|
| New dependency advisory | Owner | Check reachability, plan fix |
| Login failure burst | Owner and on-call | Check source, consider rate limits |
| Error spike | On-call | Check recent deploy, roll back if needed |
| Odd key usage | Owner | Revoke and rotate |
| Drift | Owner | Find the change, redeploy from reviewed commit |
Do not log what you should not store
Logs help incidents, but logs with passwords, tokens or personal data create their own risk. Decide what is excluded, and review logs for it early.
Review the monitoring itself
After the first month, ask which alerts fired, which were useful and which were noise. Tune, then repeat quarterly.
Where Safeguard fits
Safeguard offers continuous monitoring of dependencies and SBOMs, reachability analysis, and gates for changes, so new advisories against a promoted app reach you without a manual rescan. Run a free scan at gold.safeguard.sh/scan.
Try it yourself
Click through it at your own pace, or open it full screen. Watch how a new advisory appears against software that was already scanned.
Quick check
Who should receive the alerts?
The named owner, with a backup. Alerts sent to a shared inbox with no owner tend to be ignored.
