Watchpoints 2025–2026
Enforcement escalation
PDPC enforcement wave
The PDPC began public enforcement actions in 2024. Each publicised fine (max $144,928) generates a compliance-advisory demand spike, particularly in sectors with public consumer data exposures.
Market saturation
Initial-compliance spend fading
Initial PDPA compliance projects (2022–2024) are complete for most large corporates. Recurring work now centres on DPO services, consent-platform maintenance, and incident-response retainers.
AI data governance
GenAI and PDPA intersection
Thai corporates deploying generative AI face new personal-data processing questions. PDPA advisory firms are developing AI-governance practices; PDPC is expected to issue guidance in 2025–2026.
