Read by an AI model from open-systems.com’s own pages. What the vendor says it does, not independently verified.
IntegrationsUI-12 — integration graphDetected from this vendor's own published integration/partner pages by the enrichment loop — each entry links the exact page it was found on. Directional: "integrates with" is claimed by this vendor; "integrated by" is claimed by the other vendor's site. Coverage grows as the scan progresses.
Trust profileHow to read thisFive separate questions a buyer actually asks, each answered with its own evidence and a link to the source. There is deliberately no overall score: a single number invites comparison it cannot support, and would mostly reflect how much of Open Systems we have managed to scan rather than anything about the vendor.
Not checked means we have not looked yet, and is never counted against a vendor. Limited means we did look, but found only one line of evidence — enough to report, not enough to corroborate.

Security & trust signalsAbout these signalsCertifications are labeled by how well evidenced each one is — confirmed in a public registry, stated by the vendor, or merely detected on a page — and every claim links to its source. Security headers are checked live against the vendor's homepage, re-checked every 90 days. These are independent signals and are not blended into a single score.

Exploitation riskProbably exploitedHow this is measuredCombines four public sources, each answering a different question. CVSS (NVD) scores how bad exploitation would be. KEV (CISA) confirms exploitation is happening. EPSS (FIRST) estimates the chance of exploitation in the next 30 days. LEV (NIST CSWP 41) compounds a CVE's own EPSS history into the chance it has already been exploited. “Elevated” means EPSS at or above 10%; LEV is counted as material at 10%. LEV and EPSS are statistical estimates about a vulnerability, not findings about this vendor — and LEV is a stated lower bound, so “10%” means “at least 10%”, never “probably happened”. The underlying CVEs are matched to this vendor by name, not by exact product/version, so check each linked NVD record before drawing conclusions.

1 CVE has an estimated 10%-or-higher chance of having already been exploited despite not appearing on CISA's KEV catalog. KEV is a curated record of confirmed cases rather than a complete census, so this is where its coverage is likely thinnest — an estimate from EPSS history, not a finding. Based on a median of 5 EPSS observations per CVE.
Known CVEs (1)About this listSourced from the public NVD database, matched by vendor name. This is a name-based match, not exact version tracking — always check the linked NVD record for affected versions before drawing conclusions. “New” means published within the last 30 days. “Actively exploited” means CISA's Known Exploited Vulnerabilities (KEV) catalog confirms real-world exploitation, not just a theoretical severity score. An “EPSS” chip appears at 10% and above: that is FIRST's estimated chance of exploitation in the next 30 days, which measures likelihood rather than impact and so can differ sharply from the severity beside it. See the Exploitation risk panel above for the full picture.

Data coverage: 29/100What this measures (and doesn't)
Not a quality rating or endorsement — a measure of how much verified, disclosed data we actually have about this vendor. A low score usually means "we don't have much verified information yet," not "this is a bad vendor." Never used to sort or rank vendor lists.
The platform admin controls the formula's weights.
Data coverage profileHow to read thisThe same four components behind the data coverage score above, shaped instead of listed — a vendor strong on verification but thin on buyer feedback looks visibly different from one that's the other way around. Security and feedback plot at the neutral midpoint (50) when there's no data yet (no products tracked, no reviews), matching how the actual score itself treats missing data — not a guess either way.
