Encryption model & independent audits
How this is scored
What the vendor can prove about its security design: end-to-end encryption with named algorithms and key derivation, which fields are encrypted on the device and which are not, independent audits and penetration tests with published results, a bug bounty, and incident history disclosed.
0 — Vault contents are readable by the vendor by its own description: server-side encryption with keys the vendor holds, or no encryption of stored credentials.
3 — Client-side or end-to-end encryption described with the algorithms named; key derivation, audits and the scope of what is encrypted are basic or not described.
5 — A published security whitepaper or security page naming algorithms, key derivation and the client-side encryption model, and an independent audit, penetration test or certification (ISO 27001, SOC 2) named.
8 — A stated list of which fields are and are not encrypted (including URLs and metadata), recurring independent penetration tests or code audits with dates and reports or summaries published, a public bug bounty or vulnerability disclosure policy, past security incidents documented with their impact, and open-source clients or cryptography that can be reviewed.
10 — The design is verifiable end to end: full source or cryptographic design public, every field encrypted client-side including metadata, audits by named firms repeated yearly with full reports, a threat model that states what a compromise of the vendor's servers would expose, and incident post-mortems published.
The DevOps Engineer
The cloud security page names real examinations — SOC 2 Type 2 and ISO 27001 for the environment — plus third-party penetration tests, source-code review, and a customer's right to run their own penetration test once a calendar year with notice. The cryptography story stops at transport and appliance storage: TLS 1.2 with older versions disableable, and an encryption page managing session recordings behind a secret store. We found no public information on the algorithm or key derivation protecting stored vault credentials, published audit reports, or open-source clients I could review myself. 1 2 10
