Certpatrol

pip install cognis-certpatrol
certpatrol scan .            # → prioritized findings in seconds

🔎 Example output

Real, reproducible output from the tool — runs offline:

$ certpatrol-emit --version
certpatrol 0.1.0

$ certpatrol-emit --help
usage: certpatrol [-h] [--version] {watch} ...

TLS cert lifecycle & rogue-issuance watch via Certificate Transparency.

positional arguments:
  {watch}
    watch     Analyze a CT export against a watchlist.

options:
  -h, --help  show this help message and exit
  --version   show program's version number and exit

Blocks above are real certpatrol output — reproduce them from a clone.

Sample result format (illustrative values — run on your own data for real findings):

    ]
}

Usage — step by step

certpatrol watches TLS certificate lifecycle and rogue issuance by checking a Certificate-Transparency export against a watchlist.

1. Install:

   pip install -e .
   

2. Run a watch against a CT export (JSON / NDJSON) and a watchlist file:

   certpatrol watch --certs ct-monitor.ndjson --watchlist watchlist.json
   

3. Read the output as JSON for alerting:

   certpatrol watch --certs ct-monitor.ndjson --watchlist watchlist.json --format json
   

4. Use the exit code — the command returns non-zero when watchlist violations (e.g. rogue issuance) are found.
5. Automate in cron/CI:

   certpatrol watch --certs ct-monitor.ndjson --watchlist watchlist.json --format json > findings.json

Why certpatrol?

TLS cert lifecycle & rogue-issuance watch via Certificate Transparency — without standing up heavyweight infrastructure.

certpatrol is single-purpose, scriptable, and self-hostable: point it at a target, get prioritized results in the format your workflow already speaks (table · JSON · SARIF), gate CI on it, and let agents drive it over MCP.

Features

• ✅ Days Until
• ✅ Name Covered
• ✅ Parse Certs
• ✅ Load Watchlist
• ✅ Analyze
• ✅ Runs on Linux/macOS/Windows · Docker · devcontainer
• ✅ Ports in Python, JavaScript, Go, and Rust (ports/)

Quick start

pip install cognis-certpatrol
certpatrol --version
certpatrol scan .                       # scan current project
certpatrol scan . --format json         # machine-readable
certpatrol scan . --fail-on high        # CI gate (non-zero exit)

Example

$ certpatrol scan .
  [HIGH    ] CER-001  example finding             (./src/app.py)
  [MEDIUM  ] CER-002  another signal              (./config.yaml)

Use it from any AI stack

certpatrol is interoperable with every popular way of using AI:

• MCP server — certpatrol mcp (Claude Desktop, Cursor, Cognis.Studio, uncensored-fleet)
• OpenAI-compatible / JSON — pipe certpatrol scan . --format json into any agent or LLM
• LangChain · CrewAI · AutoGen · LlamaIndex — wrap the CLI/JSON as a tool in one line
• CI / scripts — exit codes + SARIF for non-AI pipelines

How it compares

	Cognis certpatrol	sslmate
Self-hostable, no account	✅	varies
Single command, zero config	✅	⚠️
JSON + SARIF for CI	✅	varies
MCP-native (AI agents)	✅	❌
Polyglot ports (JS/Go/Rust)	✅	❌
Open license	✅ COCL	varies

Built in the spirit of sslmate/certspotter, re-framed the Cognis way. Missing a credit? Open a PR.

Integrations

Pipes into your stack: SARIF for code-scanning, JSON for anything, an MCP server (certpatrol mcp) for AI agents, and a webhook forwarder for SIEM/Slack/Jira. See docs/INTEGRATIONS.md.
