Chronum
Security & compliance

Built to pass the review, not just the demo.

Chronum's architecture is built around the questions a security team actually asks: tenant isolation, identity, encryption, evidence, and where your data physically lives.

The pillars

Six things a security review asks about

Each is a property of the architecture rather than a setting someone has to remember to switch on.

Tenant isolation

Every tenant is isolated at four independent layers: database row-level security, ORM-level tenant scoping, token scope validation, and resolver-level authorization with object-level ownership checks before any read or write.

Identity & access

SSO/SAML, enforced multi-factor authentication, session controls, IP allowlisting, and role-based access control with custom roles — administered from a single console with full audit visibility.

Encryption

Data is encrypted in transit and at rest. Desktop capture is queued locally in an encrypted store before sync, so activity data never sits unprotected on an endpoint.

Audit spine

Every approval, correction, policy change, export, and access denial is recorded continuously to a tamper-evident audit trail — evidence is a property of how the system operates, not a project you run before an audit.

Data governance

GDPR access, export, and erasure workflows; configurable data residency; consent records; legal hold; and retention policy defined per data category, not applied as a single blunt setting.

Deployment flexibility

SaaS, single-tenant SaaS, hybrid with a customer-managed data plane, or fully on-premise and air-gapped — the same platform, so a deployment requirement doesn't force a different product.

The audit spine

Evidence as a by-product

Most organisations assemble compliance evidence after the fact, from systems that were never designed to produce it. Chronum records every user action, system action and configuration change into an append-only spine as it happens — so the evidence already exists when someone asks.

Append-only
UPDATE and DELETE are blocked at the database constraint level — inserts only.
Hash-chained
Each record carries the SHA-256 hash of the previous one, so tampering breaks the chain.
Externally checkpointed
Merkle root checkpoints are written to immutable object storage for third-party verification.
Fully attributed
Actor, tenant, action, entity, before/after state hashes and UTC timestamp on every record.
Queryable
Filter by actor, action type, entity, entity ID and date range; paginated CSV/JSON export.
Role-restricted
Spine access is limited to the Auditor and Admin roles; the Auditor role holds zero write privileges.

Access control

Four roles, four different views of the same record

Scope is enforced server-side on every request, not just reflected in what the interface chooses to show.

Employee transparency

The half most tracking tools skip

A monitoring product that employees cannot inspect is a product they will resist, and a record nobody can challenge is a weak one. Chronum gives every person a Transparency Panel over their own data, and a correction path that reaches a human rather than a void.

  • See every activity entry, screenshot and log that exists about you
  • Export up to 90 days of your own data as JSON or CSV
  • Challenge any entry through the correction workflow
  • Request human review of any AI decision that affected you
  • Personal Time is excluded from productivity and wellness analytics

Frameworks

Controls mapped to what your auditors ask for

Chronum implements the control set these frameworks require and produces the evidence continuously. Certification is an audit your organisation runs — we supply the artefacts it needs.

SOC 2 — control set & evidenceGDPR — access, export, erasure, consentHIPAA readiness packFedRAMP Moderate readiness packISO 27001-aligned controlsDORA incident reportingEU AI Act — feature inventory & oversight

Readiness packs are structured checklists of the technical and administrative controls each framework requires, mapped to the Chronum features that satisfy them and flagging any gaps — available from the Compliance & Trust Center.
