Privacy Impact Assessments: Managing Risks, Building Trust

Privacy. As children, we are taught to respect it by knocking before entering, not reading someone else’s diary, and keeping secrets when trusted. But some time along the way, things get messy. We live in a world where people share more than ever—location check-ins, fitness information, late-night Google searches—so it’s tempting to believe privacy is incompatible. 

However, most businesses get it wrong: privacy is about more than just what people disclose; it also includes what firms collect, keep, and utilize without complete openness. Customers may readily share their lives online, but that does not imply they have consented to unregulated tracking, secret data-sharing, or ambiguous retention policies.

This is why Privacy Impact Assessments (PIAs) exist. This is going to be a lengthy read, so hold on. I hope we don’t lose your attention. 

TL;DR 

Privacy Impact Assessments (PIAs) help businesses identify and mitigate privacy risks by evaluating how personal data is collected, processed, and stored—ensuring compliance with regulations like GDPR, CCPA, and HIPAA.

Conducting a PIA involves mapping data flows, assessing risks, and implementing safeguards to prevent overcollection, security vulnerabilities, and improper data sharing. DPIAs, a stricter version under GDPR, are required for high-risk data processing.

PIAs differ from DPIAs, which are mandatory under GDPR for high-risk processing (e.g., AI-driven decisions, large-scale profiling), while PIAs are a broader best practice for privacy risk management.

What is a Privacy Impact Assessment (PIA)?

A Privacy Impact Assessment (PIA) is both a process and a formal document that helps you evaluate how your organization collects, uses, stores, shares, and disposes of personal data. It’s designed to spot privacy risks early, ensure compliance with regulations, and put safeguards in place before issues turn into liabilities.

A PIA serves three key purposes:

1. It ensures your data-handling practices align with laws like GDPR, CPRA, and GLBA, as well as internal policies and industry standards.
2. It maps out how personally identifiable information (PII) moves through your systems and identifies risks at every stage—from collection to disposal.
3. It helps you evaluate existing privacy protections and find better ways to handle data that minimize exposure and strengthen compliance. 

A PIA builds a defensible privacy posture. But outside of this, are there any tangible benefits to your business?

Why are Privacy Impact Assessments important for businesses

One of the primary advantages of a PIA is risk mitigation. It forces you to evaluate how personal data moves through your organization, allowing you to uncover gaps, weaknesses, and compliance blind spots. Whether it’s insufficient encryption, excessive data collecting, or third-party threats, a well-executed PIA guarantees your firm isn’t exposed to unwanted risks. 

From a compliance standpoint, PIAs assist firms in staying ahead of new rules such as GDPR, CPRA, and GLBA, which demand organizations to examine and document their data management processes. Whether it’s insufficient encryption, excessive data collecting, or third-party threats, a well-executed PIA guarantees your firm isn’t exposed to unwanted risks. 

If your company handles customer or partner data, a properly documented PIA can act as a competitive advantage, proving that you take data protection seriously and making it easier to secure deals, especially in regulated industries.

And lastly, this is something you cannot quantify but is equally important, if not more. It helps you protect your brand’s trust. Do it right, and you’re golden; rush through it and you’re defeating its purpose. 

Conducting a Privacy Impact Assessment for your business

The process of conducting a PIA can seem daunting and complicated, but like all things, taking it one step at a time helps reduce the feeling of overwhelm.

Here are the five steps you can take to conduct a privacy impact assessment: 

Understand when a PIA is required 

Before launching a new project or data process, determine if a PIA is needed. Generally, a PIA is required when an initiative involves heightened privacy risk – for example, collecting sensitive personal data or using data in new, potentially intrusive ways​. 

Key triggers include:

1. New or changed data collection
2. Use of sensitive data or novel technology 
3. Monitoring UBA or automated decision-making
4. Regulatory mandates 

Identify and map data flows 

Once you’ve decided to conduct a PIA, the first major step is to map out all personal data flows involved. 

1. Take inventory of personal data: List all the types of personal information the project or system will handle (e.g., names, emails, IP addresses, health info, etc.). For each type, note how it’s collected and the systems or databases where it’s stored. Often, this is done using a spreadsheet or template where you enumerate data fields and attributes (also known as a Records of Processing Activities, or ROPA, under GDPR). 
2. Map the data lifecycle: Create a simple flowchart or diagram. For example, the Customer fills out an online form -> data enters the CRM database -> used by support team -> shared with a third-party shipping vendor -> stored in cloud archive -> deleted after 1 year. This visualization helps everyone see where data travels through your organization. 
3. Include purpose: For each data flow or dataset, record why you are collecting/using that data (the purpose) and, under GDPR, the legal basis for processing (e.g., consent, legitimate interest, contract necessity).
4. Document data attributes:  For each system or process, note details like how long data is retained, what security measures protect it (encryption, access controls), and how data is deleted. This complete data lifecycle view ensures you cover collection, usage, sharing, and end-of-life.

Pro  Tip – Leverage available tools to streamline data mapping. You can start with simple tools like flowchart software or Excel, but as your business grows consider privacy management software (OneTrust, TrustArc, etc.) which often include data mapping modules​. 

Assess privacy risks and compliance gaps 

In this phase, you scrutinize each aspect of the data flow against privacy principles and legal requirements (GDPR, CPRA, etc.) to spot potential issues.

1. Evaluate risks at each stage: Go through the data flow and ask, “What could go wrong here for privacy?”. For collection points, is there a risk of collecting too much data or not being transparent (no proper notice or consent)?
   1. Common privacy risk examples include: unencrypted sensitive data, using data for a new purpose without user consent, lack of an easy way to fulfill deletion requests, or vendors receiving data without proper contracts.
2. Identify compliance gaps: Cross-check your data practices against regulations like GDPR and CPRA. Are you meeting the GDPR principles of purpose limitation, data minimization, and storage limitation?
   1. For instance, a compliance gap might be that you have no defined retention period (violating storage limitation) or you’re collecting personal data without a clear legal basis (violating lawfulness under GDPR).
3. Assess likelihood and impact: For each identified risk, estimate the likelihood of it happening and the severity if it did. This helps prioritize which risks are most urgent. A simple risk matrix should (low/medium/high) work.
4. Common vulnerabilities:  One is incomplete data inventory – not knowing where personal data resides, which can lead to surprises (regulators expect you to know this​. Another is insufficient security for personal data (e.g., lacking encryption weak passwords), which can lead to breaches​.

Identify risk mitigation measures 

This is where you integrate “privacy by design” into the project by building safeguards and controls. Engage both technical staff and policymakers in crafting solutions – often, effective mitigation is a mix of technology, process changes, and documentation.

1. Prioritize and plan: If the risk is “unencrypted personal data in the database,” the mitigation might be to “enable encryption at rest on the database and restrict access – IT team to implement by X date.” If a risk cannot be entirely eliminated, plan how to reduce it to an acceptable level
2. Implement Privacy Enhancing Technologies or PETs: Encryption is one of the most powerful PETs – encrypt personal data both in transit (HTTPS, SSL/TLS) and at rest in databases or devices​. That way, even if data is intercepted or stolen, it remains unreadable. Consider pseudonymization or anonymization if feasible: replace identifiers with codes or aggregate data so individuals aren’t easily identified.
3. Policy and process improvements: Not all solutions are technical – many privacy risks are mitigated by organizational policies and procedures.
   1. To handle user rights, set up a procedure for DSARs – who will receive requests (e.g., an online portal or dedicated email), and how you will verify identity and respond within legal timeframes.

Document and review the PIA  

It’s essential to compile everything into a formal PIA report. This document serves both as an internal record and, if needed, evidence to regulators that you carried out a thorough assessment. 

Determine who in your organization needs to approve the PIA findings. Typically, the project owner or business leader and the compliance or privacy officer should sign off that the PIA is complete and the risk level is acceptable.

Make PIAs a regular part of your project and product development cycle. With each assessment, your team will get better at embedding privacy by design, and your organization will thrive knowing it can innovate while respecting individual privacy.

As privacy laws continue to evolve, regulators expect businesses to demonstrate accountability by proactively assessing data protection risks and taking corrective actions before issues arise.

This is where compliance requirements come into play. Regulations like GDPR, CPRA, HIPAA, and GLBA mandate risk assessments for high-risk data processing activities, making PIAs a critical tool for legal compliance. 

Compliance requirements related to PIAs 

Under GDPR, organizations must conduct a Data Protection Impact Assessment (DPIA) when processing activities are likely to result in high privacy risks—such as large-scale profiling, processing sensitive data, or using surveillance technology. 

CCPA/CPRA requires businesses handling sensitive personal information to conduct regular risk assessments, especially if they engage in targeted advertising, automated decision-making, or large-scale data collection.

HIPAA governs healthcare data and mandates risk assessments to protect Protected Health Information (PHI) and ensure it’s processed securely. Similarly, GLBA requires financial institutions to assess risks associated with customer financial data.

Common privacy risks identified under PIA 

A well-executed PIA helps identify common privacy risks that could lead to compliance violations, data breaches, or reputational harm. 

 Some of the most frequent risks include:

1. Overcollection of data (gathering more personal information than necessary)
2. Lack of transparency (unclear or missing privacy notices)
3. Inadequate security controls (unencrypted data, excessive access permissions)
4. Improper data sharing (third-party vendors processing data without contracts or safeguards)
5. Excessive data retention (keeping personal information longer than required)

While Privacy Impact Assessments (PIAs) help businesses identify and mitigate data privacy risks, certain regulations impose stricter assessment requirements for high-risk processing activities. 

Key differences between PIA and DPIA

A Privacy Impact Assessment (PIA) is a broad evaluation of privacy risks associated with data processing, applicable across various frameworks and industries. In contrast, a Data Protection Impact Assessment (DPIA) is a specific GDPR requirement for processing activities that pose a high risk to individuals’ rights and freedoms. 

GDPR, for instance, requires a Data Protection Impact Assessment (DPIA) in specific scenarios—such as when businesses engage in large-scale profiling, AI-driven decision-making, or biometric data processing. 

Manually tracking privacy risks, mapping data flows, and ensuring compliance with evolving regulations like GDPR, CPRA, and HIPAA can quickly become overwhelming. Which is why we might need tools.
