Artefaktum Security Workspace

When first-line diagnostics are no longer enough.

Move from individual technical signals to structured security assessment.

The Artefaktum Security Workspace provides advanced tools for domain security, supplier exposure, technical hygiene, network segmentation and defensible security decisions.

Legal / Safe Use

Useful diagnostics. Controlled boundaries.

These utilities are intended for administration, configuration review and first-line technical diagnostics. Public-data queries are passive. Browser-local tools process the supplied values in your browser. Do not use any active test against a third-party system unless you have explicit authorisation.

Passive firstDNS and RDAP queries use public registration or resolver data.
Local where possibleHashes, JWT decoding, subnet calculations and format conversions run in-browser.
No vulnerability exploitationThis workspace does not provide intrusive scanning or exploit functionality.
Point-in-time signalsResults are technical indicators, not a formal security assessment.
