Compliance Checklist

What Businesses Should Verify Now

1. Is your privacy policy updated for the latest amendments?
2. Are purposes of use sufficiently specific?
3. Do security measures cover all four categories?
4. Is a breach response manual in place?
5. Is employee training conducted regularly?
6. For cross-border transfers, have you verified destination-country protections?
7. For under-16 data, do you have parental consent mechanisms?

Secure Sharing of Compliance Documents

Data audit reports, breach incident records, and vendor contracts contain highly sensitive information. LOCK.PUB lets you store these in password-protected encrypted memos and share them only with authorized parties. Unlike email attachments, LOCK.PUB requires a password to access, significantly reducing the risk of accidental exposure.
