One of the most common incidents in businesses does not stem from sophisticated cyberattacks, but from everyday operational errors: sending the wrong file, attaching the wrong document, selecting the wrong email recipient, or misconfiguring access permissions. Precisely because these incidents seem “simple,” organizations often respond too slowly or handle them in an overly administrative manner.

From a compliance perspective, the first few hours after an incident are typically the most critical. Without prompt action, data may continue to spread, response actions may not be properly documented, and internal teams may struggle to accurately assess the impact. At this stage, what businesses need is not just to fix the mistake, but to activate a minimum incident response process with clearly assigned responsibility.

A practical tip for incident response:

Businesses should prepare a 24-hour incident response checklist for personal data incidents—even if a full incident response playbook is not yet in place.

Mini-checklist:

• Immediately stop further dissemination if still possible;

• Identify what data was mistakenly shared, with whom, and to what extent;

• Promptly notify the designated legal, IT, or information security contact;

• Record the full timeline, including actions taken, involved parties, and key timestamps;

• Conduct a preliminary assessment to determine whether escalation or further action is required.

An organization’s compliance capability is not measured by the absence of incidents, but by its ability to respond quickly, appropriately, and in a controlled manner when incidents occur.

Legal reference: Law on Personal Data Protection No. 91/2025/QH15 and its implementing regulations, including provisions on personal data security, risk management, and the handling of personal data breaches or threats thereof.
