Terms of use

This website is provided for information. By using it you accept these terms. We may revise them; the version published here is the one in force. Continued use after a change constitutes acceptance.

Published material

The Archive, research and technology pages, and material describing our sites and programmes are published by Sentinel Research Group. Dates, measurements and reference numbers are those of the originating record. Citation of released material should retain the document identifier and the date of release.

No advice, no warranty

Nothing here constitutes engineering, security, legal, medical or financial advice, and nothing should be relied upon in the design or operation of a system on which people depend. The site is provided as is. We make no warranty that it will be available, accurate or free of error, and we exclude liability for loss arising from its use to the extent the law allows.

Independence

Sentinel Research Group is an independent, privately endowed research institution. It is not affiliated with, endorsed by, or acting on behalf of any government, military, intelligence, regulatory or law enforcement body in any jurisdiction, and it holds no public authority of any kind. Where our writing uses handling markings such as “restricted” or “controlled”, those describe our own internal publication conventions and correspond to no national or international classification scheme.

Intellectual property

All text, documents, branding, illustration, layout and source code on this site are the original work of Sentinel Research Group and remain its property. You may read, link to and quote from the material with attribution. You may not republish it wholesale, present it as your own, or reproduce it in a way that implies endorsement.

Personnel and third parties

Names of staff and of third parties are withheld or replaced with internal designations where a release would identify an individual without a corresponding operational need. Enquiries about a specific designation should go to [email protected].

Third-party assets

The typeface is Space Grotesk, used under the SIL Open Font License. It is the only third-party asset the site loads. There are no advertising, analytics or tracking components — see Privacy for what that means in practice.

Security

Vulnerabilities in this website should be reported under our coordinated disclosure policy, which sets out scope, expectations and safe harbour.

Contact

Legal enquiries, including any concern about the material published here, should go to [email protected]. We read what arrives and reply to what warrants a reply.
