PrivateWiki vs. Public Wiki: Why Privacy Matters for Internal Knowledge

PrivateWiki Features to Protect Sensitive Company Knowledge

Access Control

• Role-based permissions: Grant read/edit/admin rights by role to limit who can view or change content.
• Granular page-level controls: Restrict access to specific pages or folders for sensitive projects.

Authentication & Identity

• Single Sign-On (SSO): Integrate with SAML/OAuth providers (Okta, Azure AD, Google Workspace) to enforce corporate identity policies.
• Multi-factor authentication (MFA): Require an additional verification factor to reduce account compromise risk.

Encryption

• Encryption in transit: TLS/HTTPS for all data transfers.
• Encryption at rest: AES-256 (or equivalent) to protect stored content and attachments.
• Optional end-to-end encryption (E2EE): Only clients hold decryption keys so server operators cannot read content.

Audit Logs & Monitoring

• Comprehensive audit trails: Record who accessed, viewed, edited, or deleted content with timestamps.
• Change history & versioning: Preserve prior versions and allow rollback to detect and recover from malicious or accidental edits.
• Alerting & anomaly detection: Notify admins of unusual access patterns or bulk exports.

Data Loss Prevention (DLP) & Content Controls

• Content classification & labels: Tag pages with sensitivity labels (Confidential, Internal, Public).
• Automated DLP scanning: Detect and block secrets (API keys, SSNs, credit card numbers) via pattern matching or regex.
• Watermarking & copy restrictions: Prevent screenshots/printing or apply visible watermarks on sensitive pages.

Backup & Recovery

• Encrypted backups: Regular, automated backups stored securely.
• Point-in-time restore: Recover content to a specific timestamp after data loss or corruption.

Collaboration Safety

• Secure sharing links: Time-limited, password-protected links with limited scopes (view-only, comment).
• Approval workflows: Require review/approval before publishing sensitive pages to wider audiences.

Integrations & API Security

• Scoped API keys: Limit third-party access to necessary scopes with expirations.
• Outbound data controls: Restrict integrations that can exfiltrate sensitive data.

Compliance & Governance

• Retention policies: Configure deletion or archiving schedules to meet legal requirements.
• Compliance certifications: Support for SOC 2, ISO 27001, GDPR, HIPAA considerations where applicable.
• Legal hold: Preserve specified content during investigations or litigation.

Usability & Admin Controls

• Admin dashboards: Centralized controls for permission management, audits, and security settings.
• Onboarding/offboarding automation: Automatically provision/revoke access based on HR directory events.

Best Practices (brief)

• Use SSO + MFA, apply least-privilege access, enable audit logging, run DLP scans, and maintain encrypted backups.
