How Cevro helps

  • Maps UK GDPR to the rest of your compliance program, so evidence collected for SOC 2 or ISO 27001 also counts here where it overlaps.
  • Counts your automated technical checks as evidence toward the security duty in Art. 32.
  • Gives every failing control a specific fix and a way to re-check it.
