Why Data Privacy Isn't the Same as Data Security

-



Failing to distinguish between data privacy and data security leaves businesses vulnerable to regulatory scrutiny and the kinds of breaches that erode consumer trust overnight.

Too often, organizations treat data privacy and data security as interchangeable concepts. Privacy and security are not the same, and failing to distinguish between them leaves businesses vulnerable to regulatory scrutiny and the kinds of breaches that erode consumer trust overnight and can lead to compliance gaps, security failures, and lasting reputational damage. 

Privacy and Security Are Not the Same

At its core, data privacy is about individual control over personal information. It ensures that companies collect, store, and use data ethically and transparently, with explicit consent from consumers. Privacy laws such as the European Union's General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), and the California Consumer Privacy Act (CCPA) set data access, sharing, and deletion rules to protect individuals' rights. 

Data security, on the other hand, focuses on protecting information from unauthorized access, breaches, and fraud. It involves proactive protections like encryption, fraud detection, firewalls, and security audits to safeguard sensitive data. While privacy regulations impose legal obligations, security decisions require businesses to make ongoing investments in risk management. 

Many companies assume that following privacy laws means their data is secure. But compliance alone does not prevent unauthorized access. A company can check every regulatory box yet still lack the protections necessary to keep sensitive information secure. 

Privacy and Security Require Different Strategies

Because privacy and security serve distinct purposes, they demand separate approaches. Privacy compliance ensures companies meet legal obligations under frameworks like GDPR, HIPAA, and CCPA. It focuses on data governance policies, consent management, and ethical data use to maintain transparency and consumer trust. 

Security is about active defense and applicable safeguards. It follows technical standards such as those set by the National Institute of Standards and Technology (NIST) and ISO 27001, relying on encryption, fraud detection, penetration testing, and real-time monitoring to prevent breaches and thwart malicious activity. Unlike privacy, which is about following rules, security is about staying ahead of evolving threats. 

Organizations that assume privacy compliance as a security strategy risk turning it into a regulatory checkbox exercise, leaving critical vulnerabilities unaddressed. 

Who Is Responsible for Privacy and Who Manages Security?

Another consequence of blurring privacy and security is confusion over roles and responsibilities. Without clear separation, businesses create gaps that attackers can exploit. 

Privacy oversight typically falls to compliance teams, legal officers, and data protection professionals. They ensure companies meet regulatory and ethical obligations related to consumer data. On the other hand, security is led by chief information security officers (CISOs), IT security teams, and fraud prevention professionals. These teams focus on risk assessments, access controls, and breach response. 

When these responsibilities are not clearly defined, accountability becomes blurred, response times slow, and vulnerabilities increase. Security threats require immediate action, but if security and compliance teams operate under the same umbrella, incidents may be treated as legal issues rather than urgent threats. Recognizably, this separation of duty isn't always achievable within smaller organizations, making it important to staff combined teams with succinct objectives covering both categories.

The Cost of Getting It Wrong

Failing to separate privacy and security leads to tangible business risks. Companies that mishandle privacy face regulatory penalties, lawsuits, and consumer distrust. A single misstep in data handling can trigger litigation battles and long-term brand damage. 

Security failures, on the other hand, lead to fraud, operational disruptions, and financial losses. The DOGE case is a prime example of how weak access controls can expose millions to identity theft and fraud. Regulatory compliance may reduce legal risk but does not protect businesses from cybercriminals taking advantage of poor security practices. 

A Smarter Approach to Privacy and Security

To avoid costly mistakes, businesses must separate their privacy and security strategies by doing the following:      

  • Clearly define responsibilities so privacy teams focus on compliance and ethical data use, while security teams prioritize threat detection and prevention. 

  • Ensure privacy policies do not overshadow security investments. Compliance with GDPR does not prevent breaches, but encryption, fraud detection, and security audits do. 

  • Regularly test privacy and security frameworks through scenario-based exercises that reveal vulnerabilities before a breach occurs. 

  • Improve collaboration between privacy and security teams. Cross-functional training ensures each team understands where their roles overlap and where they do not. 

The Bottom Line

Confusing privacy with security creates unnecessary risk for businesses. Regulatory compliance is important, but even the most well-regulated data can be exposed without strong security protections. By prioritizing privacy and security collectively, companies can preserve consumer trust, prevent costly breaches, and ensure data remains secure before it becomes the next headline.

Critical Vulnerability in Veeam Backup & Replication Exposes Enterprises to Remote Code Execution By : Rei Ibraima A newly discovered critical vulnerability in Veeam’s Backup & Replication software, designated as CVE-2025-23120, poses a significant security risk to enterprise environments. The flaw allows authenticated domain users to execute arbitrary code remotely, potentially leading to full compromise of backup infrastructures. About CVE-2025-23120 The vulnerability arises from an insecure deserialization issue within Veeam Backup & Replication components—particularly in the .NET classes Veeam.Backup.EsxManager.xmlFrameworkDs and Veeam.Backup.Core.BackupSummary. Improper input validation in these components allows attackers to inject malicious serialized objects that are executed on the server side, resulting in Remote Code Execution (RCE). This issue affects systems where Veeam Backup & Replication is deployed in a domain-joined configuration, which—while common—is...

  Diicot, previously known as Mexals, is a relatively new threat group that possesses extensive technical knowledge and has a broad range of objectives. Diicot shares its new name with the Romanian anti-terrorism policing unit and uses the same style of messaging and imagery. Researchers from Cado Labs reported that an emerging Romanian threat actor called Diicot is utilizing unique TTPs (Tactics, Techniques, and Procedures) and an interesting attack pattern to target victims. The researchers noted that the group has been using brute-force malware whose payloads have neither been publicly reported nor appeared in common repositories.
