Security and Access Control
Practical file security for teams: access control and least privilege, credential handling, link hygiene, retention and deletion, breach response, and what to check before trusting a vendor with client material. These pages describe what a control does rather than which certificate it satisfies. Fast.io provides encryption in transit and at rest, scoped API keys, granular permissions, workspace isolation, and an append-only audit log, on certified infrastructure partners.
The pages assume a small team with no security function, so they lead with the controls that remove the most risk for the least effort: revoking access when someone leaves, keeping links from outliving their purpose, and being able to establish what happened after the fact. Vendor questions are framed as things to verify for yourself rather than logos to look for on a page.
