The risk doesn't end at signing
A freshly signed contract often contains pricing, personal data, and proprietary terms — and it stays sensitive for the entire retention period, which can be a decade or more. Treating executed documents as "done" is how breaches and compliance failures happen.
Encryption, in transit and at rest
- In transit: every document and audit event moves over TLS. No exceptions.
- At rest: documents encrypted with strong, regularly rotated keys.
- Key management: keys stored separately from the data they protect, with access logged.
Access control that matches reality
Not everyone who can log in should see every contract.
- Role-based access. Sales sees their deals; legal sees all; finance sees executed agreements with values.
- Per-organization isolation. In a multi-tenant system, one customer's documents must be cryptographically and logically inaccessible to another.
- Least privilege by default. New users get the minimum, and access is granted explicitly.
- Access logging. Every view of a sensitive document is itself an auditable event.
Retention and disposition
Keeping everything forever is a liability, not safety.
- Set retention schedules by document type and governing law.
- Automate disposition so documents are deleted (or anonymized) when their retention period ends.
- Keep the audit trail's integrity record even after content is disposed, where law allows.
Over-retention is a quiet risk: every document you keep past its required period is data that can be subpoenaed, breached, or leaked — with no offsetting benefit.
Verifying integrity over time
Storage isn't passive. Periodically re-verify document hashes against the audit trail so silent corruption or tampering is caught early. A signed document you can't prove is intact five years later is barely better than no document at all.
