Sensitive hiring data.Clear boundaries.

Cernor gives models the context required for the current evaluation.

Source records, access, the locked Standard, policy, retention and final hiring authority stay outside model control.

01 · Data & model boundary

Your data stays separate from the judgment it produces.

Source records remain independently readable. Cernor scopes the context used for evaluation, stores model judgment separately and keeps access, policy, retention and final authority outside model control.

The judgment can change.The source record does not.

Source records — role inputs, candidate material and Follow-Up responses — remain independently readable. A model pass receives only the context required for the current evaluation: relevant role context, the candidate evidence being judged and the locked Standard. The judgment comes back and is stored separately, source-linked, versioned and receipted, and does not replace the source record. The flow passes through model processing. Source identity, access, the locked Standard, policy, retention and the final human decision do not: they stay outside model control.

02 · Security foundation

Security starts before the model call.

Encryption, tenant isolation, access control, secrets management, monitoring, recovery and secure development protect the application independently of model behavior.

Security foundation Implemented controls
Data protection

Encryption

Protected in transit and across production storage.

Tenant isolation

Workspace and project boundaries enforced server-side.

Access & secrets

Access control

Sensitive candidate and administrative actions require authorized access.

Secrets & credentials

Production and provider credentials stay server-side.

Operations

Monitoring & recovery

Operational events are recorded; candidate and project records are backed up and recoverable.

Secure development & releases

Production changes move through controlled environments and dependency checks.

03 · Data lifecycle

Retention is a policy, not a side effect.

Retention follows your organization’s policy where retention rules are available. Scoped deletion can be requested for candidate or project records and is reflected in system state.

Retention authority

Your organization

  1. Active project

    Follow the current organization retention policy.

  2. Closed project

    Continue under the configured workspace policy.

  3. Scoped deletion

    Candidate or project records can be explicitly removed.

Operational exceptions

Security, billing or legally required records may follow separately documented rules.

04 · Accountability

Every consequential change keeps a history.

Who locked the Standard. Which version governed the evaluation. What changed later.

Cernor appends new state instead of rewriting history.

At 09:14 the Hiring Lead locked Standard v3 with nine criteria and two must-haves. At 14:42 the decision updated from Current Fit 61.0 to 68.0 under policy v30 and was recorded. The next day the Hiring Lead created Standard v4 with commercial ownership elevated, and three dependent decisions were reopened; v4 is the current version and v3 is preserved and still readable under the version that produced it.

05 · Security review

Security review starts with clear answers.

Architecture, data flow, subprocessors, privacy terms and implemented controls, organized for direct security review.

Common questions
Does Cernor use customer data to train models?

No. Cernor does not use candidate or role data to train or fine-tune generalized foundation models, and does not intentionally opt it into third-party generalized model training. Production AI processing is selected and configured against documented data-handling restrictions covering training and retention.

What data is sent to model providers?

Only the context required for the current evaluation: the role, the candidate evidence being judged and the locked Standard, sent through the approved production model path.

How is customer data protected?

Candidate and role data is protected in transit and across production storage, with authenticated workspace and project boundaries enforced server-side.

Who can access candidate information?

Access follows workspace and project permissions. Sensitive administrative and consequential actions are attributable to the person who took them.

How long is data retained?

Retention follows your organization's policy where retention rules are available. Scoped deletion can be requested for candidate or project records and is reflected in system state.

Where is data processed?

Production hosting and processing locations are shared through the security review process. Contact us for current deployment details.

Is Cernor SOC 2 or ISO 27001 certified?

Not currently. We don’t claim certifications we haven’t earned. We can provide our current architecture, data flow, subprocessors and implemented controls for review.
