Article 33 of the GDPR states that organisations must have robust procedures in place to detect and investigate personal data breaches as well as report them within 72 hours.
Without extensive visibility across your network and endpoints, it can take months to identify a breach and know whether personal data has been compromised.
The cost of conducting post-event investigations will far outweigh the investment in a GDPR monitoring service, which will help to minimise security risk and provide the intelligence needed to quickly identify, remediate and report breaches to compliance standards.
