Artemis is a modular vulnerability scanner that checks website security aspects and builds easy-to-read reports to send to scanned organizations.
Summary
Artemis is an open-source, self-hosted modular vulnerability scanner built by CERT PL to check various aspects of website security and turn the results into easy-to-read reports for the organizations being scanned. It runs as a set of separate microservices, one per scanning module, so pieces can be scaled independently as load grows, which points it at teams doing large-scale or nation-level scanning rather than a single-target pentest. It is aimed at CERT teams and organizations running attack-surface or vulnerability-scanning programs across many domains at once, not at individual bug hunters. The documentation calls it experimental, under active development, and warns it doesn't yet proxy requests, so it should be run with that risk in mind. With 50 contributors, over 850 commits in the past year, and presentations at BlackHat USA and Europe, it is under active, visible development.

How Artemis helps
Which of our domains have exposed vulnerabilities that need attention right now?
runs the configured scanning modules against the domain list and reports what each one found, flagged by severity so the worst issues surface first
Which of the organizations we scan need to be notified, and with what wording?
turns raw findings into human-readable messages per organization, so a team can send them on without re-writing technical output by hand
Can our scanning workload keep up as we add more domains?
runs each scanning check as its own microservice, so the modules under the heaviest load can be scaled up independently instead of the whole scanner being rebuilt
What kinds of website weaknesses are we actually checking for across our scope?
applies its set of scanning modules to each target, each one covering a different aspect of website security, and reports what it detects module by module
Is scanning traffic going to expose the scanning infrastructure's own IP address to the targets?
sends requests directly without proxying, so targets and their logs will see the scanning host's real address rather than an intermediary
Are we running a scanner mature and active enough to depend on for ongoing, large-scale work?
is not answered by the tool itself, since this is a question about the project rather than something a scan run reports back

Nine scores for Artemis, each built from the releases, notes and API history this site tracks — and, on Researcher and Business, where it stands among every measured tool in its category and how that has moved.
Score cards are part of every paid plan.

Blank means never measured; nothing here is a filled-in zero.
Peer standings are included with Researcher and Business. See how this tool ranks against its competitors, using data we don't publish anywhere else.
See plans →Each score is 0–100 on a published rubric, derived from data this site already shows. A dimension we cannot measure says so — it is never scored 0 and never enters a rank.
How this is scored
- Shipping velocity — releases a month over the last 12 months, on a log scale where 16 a month scores 100. Needs 3 releases in the window.
- Documentation quality — the release-notes rubric published on the analytics page, unchanged.
- Breaking-change discipline — the share of releases carrying a breaking change (none scores 100, half or more scores 0). Only projects that label breaking changes are measured: a clean record cannot be told from an unlabelled one.
- Maintenance risk — quiet time measured against the tool's own release cadence (quiet longer than 90 days and three typical gaps scores 0), plus the number of active maintainers and whether contributors are growing, where known. Higher is lower risk.
- Innovation & surface — new capabilities in the feature ledger this year, API and MCP operations added, and the share of commits that are features: the mean of whichever we hold.
- Community health (open-source tools only) — each is a direction, not a size: contributors this year against last, the bus factor now against a year ago, and issues closed per issue opened, where steady scores 50, doubled 100 and halved 0; plus the median time to a maintainer's first reply (an hour scores about 100, a month or more 0). A commercial card has no repository and carries none of the four.
- Documented delivery (commercial tools) — when a vendor's documented new capabilities have slowed against its own baseline, that counts against the overall standing as heavily as two low dimensions. Steady delivery, or too little history to judge, leaves the standing alone; it is never a sixth score.
- Open-source tools are scored on repository signals; commercial tools on their published changelog. Ranks compare tools within one category and one profile and need at least five measured peers; the overall standing needs three ranked dimensions. Best-in-breed or consolidator is a shape, not a quality, and is never scored.

Nothing first seen in this window. That doesn't mean Artemis shipped nothing, only that we found no record of it.
How we count
Read from 1 of 19 release notes and docs updates we hold for Artemis. "First seen" is the earliest note that names something; "last" is the latest. Our history may start partway through Artemis's life, so an old integration can show a recent first-seen date.
Each change counts once: "added 40 checks" is one line, so the numbers measure how often coverage moves, not how big the catalogue is or how well it detects.
