Everything here is free to use, and every download below belongs to the current release. The current materials are available under the owner’s permitted-use terms; availability is not an open-source grant, and the difference matters, so it is stated rather than implied. No account, no email address, no sales call.
Which release do you need?
Current release
TID-CMM model 1.6.0 · documents v1.6
The current model, the current white paper and workbooks, and the current assessment. This is the version to cite, and the only assessment supported online.
Previous release and historical documents
TID-CMM model 1.5.0 · documents v1.4 · site state 20 August 2026
Superseded — historical use only. Preserved so that a report produced under the previous version can be reproduced, an older citation can be checked, and an earlier historical assessment can be understood. It is not a second supported assessment.
Everything below this point is the current release.
Licence and permitted use
TID-CMM is free to use under the permissions on the licence page. Assess your own organisation, assess clients for a fee, cite and quote with attribution, and link to the project — none of that needs permission. Republishing the model or the datasets, publishing a derivative, embedding it in another product, rebranding the tool or redistributing the offline build does need written permission, and it is a conversation rather than a refusal.
Free to use does not mean open source, public domain, or permission to redistribute, rebrand or create derivative products. The assessment and site implementation is copyright, all rights reserved. MITRE ATT&CK® content inside the datasets stays governed by MITRE’s own terms. Model 1.5.0 and documents v1.4 keep the licence they were released under.
