SSL cert monitoring - boring, essential. Does it without fuss.

SSL cert monitoring is table stakes. Works fine. Would want alerting hooks before trusting it in a real ops workflow.

Marcus Webb2026-03-27

3.0 / 5

SSL and domain registration monitoring. Covers the basics, nothing more.

Cert expiry and domain registration checks in one tool. Solid for asset inventory. Missing alert threshold configuration and wildcard cert…

Does cert expiry monitoring but the description says nothing about alert thresholds or integrations with existing tooling. Thin docs on a c…

03SECURITYWHAT WE CHECKED

Security flags foundOur static scan found signals worth reviewing before you trust this with an agent. See exactly what, per check, below.

Telemetry disclosureUndisclosed egress detected.Static checks found network calls the docs do not mention. Disclosed telemetry is common and fine, silent telemetry is the finding.

Security tierTier 1, Contained.No network access and no credentials. Runs entirely on its own. What tiers mean

Install-time hooks & dependenciesno flags

Code that runs when you install it, before you ever call a tool.

Runs code / shell commandsno flags

Whether the server can execute commands on your machine.

Secrets & credentialsno flags

How it reads, logs, or transmits keys and tokens. Scam/wallet-drainer patterns land here.

Network calls out3 findings

MEDIUMsrc/index.ts:166 — Hardcoded external endpoint 'data.iana.org'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

MEDIUMsrc/tests/domain-lookup.test.ts:84 — Hardcoded external endpoint 'icann.org'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

MEDIUMsrc/tests/domain-lookup.test.ts:151 — Hardcoded external endpoint 'httpbin.org'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

Prompt-injection passthroughno flags

Whether it pipes untrusted external content back as agent instructions.

Permission scope breadthno flags

How much access it asks for versus what its job needs.

How to read this: these are static checks over the source at a point in time. They catch the patterns above, not everything. Absence of a flag is not absence of danger, and a tool that runs cleanly can still behave differently once installed. We do not call any tool simply "safe". Runtime-behavior checks are the next layer we are adding.
