Safeguarding PII: Risks, Penalties, and Proven Protection Strategies

Personal data is a prime target for cybercriminals. Mishandled data opens the door to costly consequences.

Today’s most common threats include:

• Phishing attacks: These attacks trick employees into revealing login credentials or clicking malicious links that install malware. Attackers often impersonate trusted sources, such as company executives or well-known vendors, making phishing one of the most successful entry points for data breaches.
• Insider threats: These risks can stem from both malicious insiders seeking to steal data and well-meaning employees who make costly mistakes, such as sending sensitive files to the wrong person. These threats are difficult to detect and often go unnoticed until the damage is done.
• Ransomware: Attackers encrypt critical files and demand payment in exchange for restoring access, often targeting sensitive PII to pressure organizations into compliance. Beyond immediate operational disruption, ransomware attacks can lead to long-term data exposure and reputational harm.
• Shadow IT: When employees use unauthorized apps or tools (file-sharing platforms, messaging apps), they create security blind spots. These unmonitored systems often lack proper encryption or access controls, increasing the risk of data leaks and non-compliance with data protection laws.

Beyond external threats, simply storing or sharing PII incorrectly can result in severe reputational damage, lost business, and regulatory fines. As data privacy laws evolve and individuals become more informed, organizations face greater pressure to ensure compliance and maintain trust.

From a compliance perspective, regulations require proactive risk management. Government agencies now expect organizations to establish proactive controls and demonstrate accountability from data collection to disposal.

A data breach doesn’t just affect your systems; it affects your bottom line, reputation, and legal standing. Even a single incident can damage years of brand trust and prompt increased regulatory scrutiny.

What Qualifies as a Breach?

A breach occurs when PII is accessed, disclosed, or used without authorization, whether through hacking, misconfigured systems, or employee mistakes. Regardless of the cause, the consequences can be severe, ranging from legal penalties to long-term reputational harm.

Financial Penalties:

GDPR: Up to €20 million or 4% of global annual revenue.

These penalties are designed to be dissuasive and reasonable to the organization’s level of non-compliance with data protection or reporting requirements

HIPAA: Up to $50,000 per violation, with annual caps in the millions.

Fines vary based on the level of negligence and can escalate quickly if corrective actions are not taken promptly.

CCPA: Up to $7,500 per intentional violation.

In addition to state enforcement, businesses may also face civil lawsuits from affected consumers in the event of a data breach.

Compliance Incidents

• British Airways (2018): Fined £20M ($26M) for failing to protect personal and payment data of 400,000 customers.
• Anthem Inc. (2015): Paid $16M to settle HIPAA violations after hackers accessed nearly 80 million records.
• Meta (2023): Received a €1.2B ($1.4B) fine under GDPR for transferring personal data of EU users to the U.S. without sufficient protections in place, making it the largest fine issued under the regulation to date.

Non-compliance with data privacy regulations is beyond an operational shortcoming. It represents a significant business risk with legal, financial, and reputational consequences.

Data mishandling can happen in various ways, often with serious consequences. To illustrate this, let’s examine two real-world examples.

Scenario 1: Healthcare Clinic & Indirect PII

A clinic published de-identified patient data for research. However, the dataset included ZIP codes, birthdates, and gender, which are classic indirect PII identifiers. When combined with public records, researchers were able to re-identify patients.

What went wrong: Failure to recognize that indirect PII can still lead to identification.

How to prevent it: Use stronger anonymization techniques and understand the re-identification risks of indirect data.

Scenario 2: Unencrypted Email Storage

An established SME (Small or Medium-sized Enterprise) stored years of unencrypted customer emails containing names, addresses, and payment details, which are direct PII identifiers. After a phishing attack, those messages were leaked and sold on the dark web.

What went wrong: Lack of encryption, weak access controls, and outdated data retention.

How to prevent it: Encrypt sensitive data, apply retention policies, and use archiving solutions that support compliance and security.

Reducing the risk of exposing Personally Identifiable Information (PII) requires a proactive and structured approach.

The following best practices can help organizations strengthen data protection and maintain regulatory compliance:

• Audit Regularly: Know what PII you have, where it’s stored, and who has access.
• Limit Access: Limit access exclusively to personnel with a validated business need
• Purge Redundant Data: Remove outdated, duplicate, or unnecessary data.
• Build a Security Culture: Train employees on recognizing threats such as phishing and social engineering.

These actions can aid in reducing the risk of a data breach. In addition, they also support compliance with data minimization and retention principles outlined in regulatory laws (GDPR, HIPAA)

A strong privacy program requires a layered defense.

Think of your strategy as a triangle of Prevention, Detection, and Response. Each layer plays a critical role in reducing risk and ensuring swift action when incidents occur.

• Prevention: Limit data collection, implement access controls, and encrypt data. Proactively reducing the amount of data you collect and securing it at every touchpoint minimizes the risk of exposure.
• Detection: Use monitoring tools and audit logs to track abnormal activity. Early detection enables faster containment of threats and reduces the potential impact of a breach.
• Response: Have a documented breach response plan, including regulatory notification timelines. A well-rehearsed plan ensures your organization can act quickly, maintain compliance, and preserve trust during a security incident.

Other best practices include:

• Enforcing multi-factor authentication (MFA)
• Requiring strong password policies and regular updates
• Ensuring team members understand the difference between PII identifiers and how they must be handled

Together, these practices create a resilient foundation for safeguarding PII and building long-term trust with customers, partners, and regulators.

Protecting PII requires the right tools, policies, and practices, specifically when it comes to how data is collected, stored, and accessed.

Data Minimization

Collect personal data that is necessary for your intended purpose. For example, collect an email address to send a confirmation, not a home address or date of birth, unless it’s essential for business operations or compliance. Asking for extra information when it’s not required increases risk and regulatory exposure.

Practicing data minimization mitigates your overall data footprint and simplifies compliance with privacy laws.

Encryption

Encrypt PII both in transit and at rest to ensure that sensitive data remains unreadable to unauthorized users. Even if systems get breached, encryption acts as a final safeguard by rendering the stolen information useless.

This protective measure strengthens and reinforces both data protection and regulatory compliance.

Access Control

Apply strict access controls and ensure all user activity is logged for accountability. Use role-based access to limit internal risk, and set automatic expiration policies for data that is no longer needed.

Regularly review permissions to ensure access remains aligned with users’ responsibilities and business needs.

These key measures establish a strong foundation for a secure data environment, meet the standards established by HIPAA and GDPR, and reflect an organization’s commitment to privacy and regulatory compliance.

The data landscape is evolving rapidly, and new risks are emerging from powerful technologies. Organizations must stay proactive by continuously updating their privacy strategies to address these evolving challenges.

AI & Machine Learning

AI can derive sensitive information from benign data, causing the line between direct and indirect PII to blur. For instance, algorithms can predict a person’s health risks from shopping habits or browsing data.

Predictive Profiling & Inferred Data

This type of derived personal information is not always classified as personal data under existing regulations, yet it carries comparable risks. While legislation may eventually address these gaps, forward-thinking organizations should already treat such data with the same level of sensitivity and protection.
