Overview
A Data Protection Impact Assessment (DPIA) is the structured analysis you run before launching any processing activity that is likely to result in high risk to the rights and freedoms of data subjects. PDPL Article 25 and its Implementing Regulation make DPIAs mandatory for specific scenarios — and recommended as best practice for any non-routine processing. This guide gives you the decision tree, the 12-section template, the retention schedule, and how to evidence it for SDAIA inspection.
When a DPIA is mandatory
DPIA is required when at least one of the following is true:
- Large-scale processing of sensitive personal data (health, biometrics, financial, religion, criminal, children).
- Systematic monitoring of a publicly accessible area on a large scale (CCTV with facial recognition, public Wi-Fi tracking).
- Automated decision-making producing legal or similarly significant effects (credit decisions, AI-driven hiring, KYC denial).
- New technologies whose privacy implications are not yet well understood (LLM-based customer service, behavioural biometrics).
- Cross-border transfer to non-adequate jurisdictions.
- Combination of datasets from different sources.
Decision tree
Is the processing new or substantially changed since last DPIA?
├── No → no DPIA needed; re-check annually
└── Yes ↓
Does it match any mandatory trigger above?
├── Yes → DPIA required
└── No ↓
Does it involve any of:
- children's data
- profiling for marketing
- innovative use of existing tech
- public-interest processing
├── Yes → DPIA recommended (and prudent for SDAIA audit)
└── No → record reason and exit
The 12-section DPIA template
1. Identification
- DPIA reference.
- Date initiated.
- Author.
- Sign-off holders (DPO, business owner, security).
- Status (draft / approved / superseded).
2. Description of processing
- Plain-language description.
- Process flow diagram.
- Systems involved.
- Number of data subjects expected per year.
- Geographic scope.
3. Data inventory
| Category | Source | Mandatory? | Retention |
| Full name | Customer form | Yes | 7 years |
| National ID | Customer form | Yes | 7 years |
| Mobile | Customer form | Yes | 7 years |
| Geolocation | Mobile app | No | 12 months |
| Device fingerprint | Mobile app | No | 24 months |
| Behavioural score | Internal model | No | 12 months |
4. Lawful basis
For each purpose: which PDPL Article 6 lawful basis, and why it is the most appropriate.
5. Necessity and proportionality
Why is each data element needed? Is there a less-invasive way? Where are minimisation opportunities?
6. Risks to data subjects
| Risk | Likelihood | Severity | Inherent | |---|---|---|---| | Unauthorised access to ID + mobile | Possible | Significant | High | | Re-identification from behavioural profile | Unlikely | Significant | Medium | | Discriminatory automated decision | Possible | Severe | High |
7. Mitigations
| Risk | Mitigation | Residual | |---|---|---| | Unauthorised access | KMS + IAM least-privilege + access reviews | Low | | Re-identification | Pseudonymisation + 90-day data deletion | Low | | Discriminatory decision | Human-in-the-loop review + model bias audit quarterly | Medium |
8. Cross-border analysis
If any element transfers outside KSA: which mechanism (adequacy / SCC / BCR / derogation), which supplementary measures.
9. Data subject rights
How will rights be honoured for this processing (access, correction, erasure, objection)?
10. Consultation
Were any stakeholders consulted (security, legal, ethics committee, sample of data subjects)? Document the consultation.
11. Outcome
- Proceed.
- Proceed with conditions (list).
- Pause and redesign.
- Reject.
12. Review schedule
Re-assess every 12 months or upon material change.
Retention schedule
| Artefact | Retention | |---|---| | Approved DPIA | Lifetime of processing + 3 years after retirement | | Consultation evidence | Same as DPIA | | Periodic review notes | 3 years |
How SDAIA evidences DPIAs
In an inspection SDAIA may request:
- DPIA register.
- A sample of three DPIAs covering different risk levels.
- Evidence the DPO signed off.
- Evidence mitigations have been implemented.
- Evidence the 12-month review was performed for matured DPIAs.
Common gotchas
- DPIA written after go-live — fundamentally undermines the assessment.
- DPIA marked "low risk" without justification.
- DPIA never updated despite a material change.
- DPIA owner is the security team only — must include the business owner.
Conclusion
A DPIA is the strongest evidence you have that you took privacy seriously by design, not retrofitted. Spend a day on a real one rather than a week on three superficial ones — quality over quantity wins audits.
