Sentinel

Sentinel is a verified web directory organised by subject desk, carrying 832 confirmed listings across 22 categories. It operates in the wire-service tradition: factual, on-the-record, and maintained continuously.

Yes. Sentinel does not charge submission or listing fees. Every verified entry appears in its subject desk on the same footing as all other filings — no paid tiers, no premium placement.

Listings are grouped into 22 subject desks — from the Gaming Bureau and Health Brief to the Digital Desk and Technology Wire. Each desk covers a distinct sector of the web, making it straightforward to locate operators in a given field.

Use the Add a Site form available from any page. Provide your domain, a short title, a brief description, and select the most relevant desk category. Submitted sites are reviewed before publication.

Most submissions are processed shortly after filing. The desk confirms the domain resolves and places the entry in the appropriate category. Submissions with a domain that is not yet live at the time of filing may be delayed.

Contact Sentinel through the Add a Site page with your domain and the correction or removal request. Updates are processed on the same basis as new submissions.

Sentinel lists any operator with a live, resolving web presence across its 22 subject desks. Listings are filed without editorial endorsement or quality assessment — readers consult the directory and deal with operators directly.
