GxP Copilot · Real e-signatures, not just checkboxes

Signed means signed. Frozen means frozen.

Electronic signatures require the ceremony 21 CFR Part 11 demands — including re-authentication, meaning, name, timestamp and content binding. Authors cannot approve their own drafts. Signed versions cannot be silently edited. Regulators get real Part 11 posture, not checkbox posture.

GxP Copilot: FDA 21 CFR Part 11 Compliance

Anchored to requirementsLinked as it is drafted

Human reviewBefore anything is approved

In short

21 CFR Part 11 compliance means electronic records and signatures an inspector can rely on. GxP Copilot re-authenticates the signer at every signature, records the signature's meaning, binds it to the exact content signed, freezes the signed version so it cannot be altered, and keeps an append-only audit trail whose integrity can be verified on demand.

The problem

Approve buttons that call themselves signatures

A great many systems describe a button labelled Approve as an electronic signature. The user is already logged in, nothing is re-authenticated, the record of the approval sits beside the document rather than bound to it, and the document stays editable afterwards.

None of that satisfies Part 11, and the gap usually surfaces during an inspection rather than during procurement, because the vendor's compliance page said the words and nobody tested what the button actually did.

How GxP Copilot handles it

A signature that behaves like one

Signing requires the signer to re-authenticate, not merely to be logged in. The signature records who signed, their role, the meaning — authored, reviewed, approved — and the time in UTC, and those appear on screen and in the exported record rather than only in a log.

The signature is bound to the exact content that was signed. Afterwards that version is frozen: its content, hash, version and file cannot change, it cannot be deleted, and it cannot be returned to an editable state.

What 21 CFR Part 11 asks an electronic signature to show: the signer’s printed name, the date and time, and what the signature means (§11.50). The signer re-enters their credentials at the moment of signing (§11.200).

Separation the system enforces

An author cannot approve their own record. Reviewer and approver are distinct from the author and from each other across the cycle, and nobody can witness their own execution. These hold because the system enforces them, not because a procedure asks people to remember.

Where several records are signed together, the batch requires a full re-authentication and produces one signature per record, rather than one signature covering a list.

An audit trail you can verify

The trail is append-only and tamper-evident, captures the change and its audit entry together, and its integrity can be checked rather than asserted. The standard inspection question about whether records could have been altered becomes a check with a result instead of a description of controls.

Exports carry evidence with its metadata, so a printed record retains what makes it meaningful rather than becoming an undated screenshot.

What makes an electronic signature Part 11 compliant?

Under §11.50 the signed record must carry the signer's printed name, the date and time, and the meaning of the signature. Under §11.70 the signature must be permanently linked to the record so it cannot be copied or transferred. Under §11.200 a non-biometric signature uses two components with re-authentication at signing.

Is an Approve button an electronic signature?

Not on its own. If the user is not re-authenticated, if the meaning is not recorded, if the approval is not bound to the exact content signed, or if the record remains editable afterwards, it does not meet Part 11. This gap is common and usually surfaces during an inspection rather than during procurement.

Does using GxP Copilot make our system Part 11 compliant?

It provides the controls Part 11 requires for the records it holds, and supplier evidence toward your own assessment. It does not replace your validation of the platform for your intended use, nor your own procedures — training, accountability policies and the FDA certification letter under §11.100(c) remain yours.

AI Classification Engine

A guided intake — accelerated by AI, decided by your team — produces GxP impact, GAMP category and composite risk, along with the exact reasoning behind each result. Instead of week-long assessments, you get a classification you can defend to an inspector on the same day. The AI accelerates the input; the classification itself is transparent and controlled.

Learn more about AI Classification Engine Risk-Based Validation Scoping

The Strategy Engine picks the applicable deliverable set for each GAMP category and scales test rigor to per-requirement risk under CSA — choosing between scripted testing, unscripted verification, and leveraged supplier evidence. The output is a validation plan sized to reality, easy to defend, and quick to execute.

Learn more about Risk-Based Validation Scoping AI Risk Assessment

Every requirement is scored against an ICH Q9 lens for severity, probability and detectability. That score drives the test strategy, the traceability coverage and the inspection-readiness view — so risk stops being a compliance formality and starts sizing your actual work.

Learn more about AI Risk Assessment Document Control & Versioning

Every document version is fingerprinted and tagged with its provenance and any AI assistance used. Data-driven sections stay canonical across every deliverable — so what you sign is what you keep, and what you keep is what you show an auditor.

Learn more about Document Control & Versioning AI Validation Document Drafting

The Documentation Engine drafts your validation deliverables in the style of the templates your organisation already uses — with confidence checks, review gates, and a fully functional fallback when the AI is unavailable. Your team stays in control; the platform removes the drudge work.
