Field Guides

Practitioner references for the work security teams actually do. Cloud security detection, digital forensics and incident response, and the adversary tradecraft that informs both. Every guide is built to be used on the job, not skimmed once. No account needed.

Cloud Security

10 guides

Detecting and defending Microsoft 365 and Entra ID. The detection reference anchors this set, with deeper guides on the query language, the identity plane, and the engineering discipline behind production detection.

DFIR

Digital forensics and incident response. Artifact references, native command guides, and the searchable investigation tools a responder keeps open on the second monitor. Guides marked Interactive are searchable apps rather than reading references.
