Risk insight: This is a critical compliance failure. GDPR Art. 33(2) requires processors to notify the controller 'without undue delay,' and controllers must report to the regulator within 72 hours. A discretionary, post-investigation timeline defeats that obligation.
Safer rewrite: DataNexus shall notify the Controller without undue delay and in any event within 24 hours of becoming aware of a personal data breach, and shall provide all information reasonably necessary for the Controller to meet its own notification obligations, including the nature of the breach, categories and approximate number of data subjects, likely consequences, and remediation measures.
Law ref: GDPR Art. 33(2); India DPDP Act 2023 §8(6)
Worst case: A breach is discovered weeks after the fact; the Controller misses its 72-hour window and faces a regulatory penalty plus reputational harm.
