Read this page as one judge. Each weighs the same scores by what they care about.

The Compliance Auditor

Weighted verdict

Prepares the ISO 27001 and NIS2 evidence and has to show who could see the firewall admin password last March. Wants event logs that cover views and copies, export to the SIEM, enforceable policies, and the contracting entity, hosting and subprocessors named.

Same scores as the panel view — this lens weights them the way this judge cares.

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 — Security described in adjectives ("bank-grade", "military encryption") with no architecture, no audit and no statement of what the vendor can read.

3 — Encryption algorithms named and "zero knowledge" claimed, but no whitepaper, no statement of which fields stay unencrypted, and audits mentioned without dates, auditors or results.

5 — A published security whitepaper naming algorithms, key derivation and the client-side encryption model, a stated list of what is and is not encrypted (including URLs and metadata), and a named independent audit or certification (ISO 27001, SOC 2) with its date.

8 — Recurring independent penetration tests or code audits with 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.

Report an error

The Compliance Auditor

The captured security pages name the cryptography — vaults encrypted with 256-bit AES-GCM, OpenPGP with Curve25519 — and state that every field including usernames, web addresses and notes is encrypted and that the vendor has no technical means to read contents, backed by open-source clients and a public bug bounty. We found no public information on independent audits or penetration tests with named auditors, dates or published results, and none on disclosed past incidents, so for ISO 27001 purposes the design claims stand largely on the vendor's own description. 5 7 3

Sharing, roles & recovery

How this is scored

How credentials are shared and governed across a company: shared vaults or collections, role-based permissions, view-only and time-limited access, admin account recovery, emergency access, and what happens to shared items when an employee leaves.

0 — Personal vaults only, or sharing by sending a password to another user with no permissions and no record.

3 — Shared folders with all-or-nothing access, no roles, and no stated process for recovering an account or reclaiming credentials from a departing employee.

5 — Shared vaults or collections with read, edit and manage permissions, groups and admin roles, an admin recovery mechanism documented with its key model, and offboarding that transfers a leaver's shared items.

8 — Granular permissions down to hiding the password while allowing autofill, time-limited and one-time sharing with external parties, emergency access with a waiting period, delegated administration per team or location, and approval workflows for sensitive items.

10 — Access is governed and provable: least-privilege defaults, recovery and emergency access designed so the vendor never holds a key and stated so, periodic access reviews supported in the product, and every grant, change and revocation attributable to a person.

Report an error

The Compliance Auditor

Vault sharing with selectable access levels, single-item or whole-vault sharing, and secure links for outsiders with expiry and view limits are documented, alongside emergency access on paid plans and organisation-wide toggles for individual-item sharing and sharing outside the organisation. The access levels themselves are never enumerated, and we found no public information on an admin recovery mechanism and its key model or on how a leaver's shared items are reclaimed. 7 8 1 11

Report an error

SSO, directory sync & provisioning

How this is scored

How the vault fits into the company's identity stack: SSO with Entra ID, Okta or Google, and the key model behind an SSO unlock; SCIM or directory sync for joiners and leavers; MFA options including hardware keys; and passkey support for users and the vault itself.

0 — Each user creates an account by email; no SSO, no directory sync and no MFA beyond an app code.

3 — SSO available only to sign in to the admin console or on the top tier with no description of how the vault is then decrypted, and users provisioned by CSV invite.

5 — SSO with named identity providers (Entra ID, Okta, Google) documented with how the vault key is derived or released, SCIM or directory sync for provisioning and deprovisioning, and MFA including FIDO2 or hardware keys.

8 — SSO unlock designed so the vendor cannot derive the vault key and stated so, group sync driving vault permissions, automated suspension on deprovisioning, conditional access or device policies, and passkeys stored and used across platforms.

10 — Identity is integrated without trust shortcuts: the SSO key model published and independently reviewed, deprovisioning that revokes vault access and shared items immediately with a log entry, passwordless vault unlock with passkeys, and support for the customer's own key-management or trusted-device approval.

Report an error

The Compliance Auditor

SCIM provisioning is documented step by step for Okta and Microsoft Entra with create and deactivate actions plus groups, passkeys are supported across all devices, and two-factor authentication can be enforced by policy. We found no public information on how the vault key is derived or released under single sign-on, on hardware security keys, or on conditional access and device policies. 9 10 5 11

Report an error

Audit logs, policies & reporting

How this is scored

What an administrator and an auditor can see and enforce: event logs of access and changes, password health and breach reports, enforceable policies (master password, MFA, sharing, export), SIEM integration, and reports an ISO 27001 or NIS2 audit can use.

0 — No audit log and no admin policies; the administrator sees a user list.

3 — A basic activity list and a password-strength score, but no exportable log, no enforceable policies, and no record of who viewed or copied a shared credential.

5 — Event logs covering logins, item access, sharing and admin changes, exportable or available through an API, enforceable policies for master password and MFA, and password health and breach-monitoring reports.

8 — Native SIEM integration with named targets (Splunk, Microsoft Sentinel, Elastic or syslog), policies for sharing, export and browser-extension behaviour, log retention stated, and compliance reports aligned to ISO 27001, NIS2 or BSI IT-Grundschutz.

10 — Auditability is complete: every view, copy, autofill and permission change logged with user and device, logs tamper-evident and retained for a configurable period, alerting on anomalous access, and an auditor role that can read logs without access to secrets.

Report an error

The Compliance Auditor

Team policies are real and enforceable — two-factor authentication, data export, sharing outside the organisation, vault creation and password-generator rules — and Sentinel gives admins organisation-wide sign-in events with location, ISP and device, plus password health and breach-monitoring reports. We found no public information on logs of item views or copies, on exporting logs to a SIEM, on log retention periods, or on reports an ISO 27001 or NIS2 audit could rely on. 11 12 5 1

Report an error

Hosting choice, offline access & export

How this is scored

Where and how the vault runs and how the data leaves it: cloud region choice, a self-hosted or on-premises option, offline access during a vendor outage, client coverage across operating systems and browsers, and a complete, documented export and import path.

0 — Cloud only in an unstated region, no offline access, and no export or an export that drops attachments and shared items.

3 — Cloud with a region named, apps for common platforms, and an export in CSV only that leaves out attachments, folders, TOTP seeds or custom fields.

5 — An EU region or self-hosted option, offline read access on desktop and mobile, clients for Windows, macOS, Linux, iOS, Android and the major browsers, and an export that covers all item types including attachments.

8 — Both EU cloud and self-hosted or on-premises deployment documented, a status page with incident history, encrypted full-fidelity export and import from named competitors, and vault access continuing during an outage of the vendor's service.

10 — The customer can run and leave the vault on their own terms: self-hosting with documented high availability and backup, an open or documented export format that preserves structure, permissions and history, and a stated procedure for continued access if the vendor ends the service.

Report an error

The Compliance Auditor

Clients cover Windows, macOS, Linux, Android, the major browsers and a web app, and export offers a PGP-encrypted JSON archive with import documented from a dozen named competitors, under an SLA targeting 99.95% monthly uptime with service credits. We found no public information on self-hosting or a selectable data region, on offline access during a vendor outage, or on a status page with incident history, and the captured client lists show no iOS. 1 14 13 4

European sovereignty

How this is scored

Who the contracting entity and the parent company are, where vault data and metadata are hosted, and who the subprocessors are. Independently sourced by the sovereignty pipeline; end-to-end encryption narrows what a foreign authority could compel, but metadata, logs and the update channel for the client software remain in the vendor's hands, so the chain still counts.

0 — Non-EU vendor and contracting entity, hosting unstated, and subprocessors unnamed.

3 — An EU data region offered while the contracting entity and parent are non-EU without a stated safeguard, or the subprocessor list is absent.

5 — EU hosting as standard or selectable and an EU contracting entity, but the parent company or parts of the chain (support, analytics, email, client distribution) are non-EU.

8 — EU hosting on named infrastructure, EU contracting entity, subprocessor list published with locations, a DPA covering vault metadata and logs, and a self-hosted option that removes the vendor from the data path.

10 — Sovereign end to end and evidenced: European ownership, entity, hosting and every subprocessor, certifications published (ISO 27001, BSI C5 or equivalent), and source code or builds verifiable so the client update channel is not a blind trust in the vendor.

Report an error

The Compliance Auditor

The contracting entity presents itself as Swiss and states it sits outside US and EU jurisdiction. We found no public information on where vault data and metadata are actually hosted, on the ownership chain, or on any subprocessor, so the chain from metadata and logs to the client update channel cannot be assessed from public pages. 5 4 1

Report an error

Pricing transparency

How this is scored

Whether a buyer can compute the real annual cost from public pages alone: price per user and tier, which features (SSO, SCIM, SIEM, self-hosting) sit in which tier, minimum seats, add-ons, and the minimum term.

0 — No public prices at all; every tier is a sales conversation.

3 — A starting price exists, but which business features (SSO, SCIM, audit logs) sit in which tier is unclear — the invoice is unknowable.

5 — Per-user tier prices public with the main features per tier, but at least one commonly needed piece (SSO, SIEM integration, self-hosting, minimum seats) is unpriced or "on request".

8 — Every tier priced publicly with its feature set and seat minimum, add-on prices listed, self-hosted licensing stated, minimum term and VAT treatment given.

10 — Complete price computability: annual invoice derivable for a given number of users, with every add-on, self-hosting licence, support level and renewal condition published.

Report an error

The Compliance Auditor

The captured pricing page lays out tier features with seat minimums and the user counts that unlock phone support or a dedicated account manager, but shows no per-user price figures. We found no public information on prices or tier placement for single sign-on, SCIM and audit logging, on add-ons, or on minimum terms, and the business trial itself runs through contacting the sales team. 2 1
