Ask most people in a security team what “data protection” means and they will likely describe a set of technical controls: encryption, access management, DLP tools, firewalls. Ask someone in a legal or compliance team the same question and they will describe consent frameworks, data subject rights, retention schedules, and lawful basis for processing. Both answers are correct. Neither is complete. And the gap between them is where a significant amount of regulatory exposure now lives.
Data security and data privacy are related disciplines, but they are not the same thing — and in 2026, the cost of treating them as interchangeable is rising fast. GRC professionals are increasingly being asked to bridge this gap, building frameworks that satisfy both the technical demands of security teams and the rights-based expectations of privacy regulators. That is a harder job than it looks.
Defining the Distinction
The starting point is definitional clarity. Data security is about protecting data from unauthorised access, theft, corruption, or loss. It asks: is this data safe? The tools it reaches for are technical — encryption, access controls, monitoring, incident response. Its concern is with the integrity and confidentiality of data as an asset.
Data privacy, by contrast, refers to the protection of personal information and ensuring that data is collected, processed, stored, and shared in accordance with legal and ethical standards. It asks: should we have this data at all, and are we using it in ways that individuals would reasonably expect? Its tools are legal and procedural — consent mechanisms, data minimisation, subject access requests, impact assessments.
A company can have excellent data security and still be in serious breach of privacy law. An organisation with robust encryption, tight access controls, and a mature SOC can still be collecting data it was never entitled to, sharing it with third parties without adequate consent, or retaining it long past the point of legitimate purpose. The controls work. The governance doesn’t. Regulators see both — and increasingly, they are penalising the governance failures just as hard as the security ones.
The Enforcement Reality
This distinction matters practically because enforcement is now explicitly targeting structural governance failures, not just breach outcomes.
Regulators are increasingly penalising structural control deficiencies — weak vendor management, missing encryption, inadequate logging — rather than waiting for a breach to occur. Enforcement is moving from “what happened” to “what controls were you missing when it happened.”
GDPR enforcement has reached €7.1 billion in cumulative fines, with €1.2 billion levied in 2025 alone. France’s CNIL issued €486.8 million in 2025, frequently targeting cookies, employee monitoring, and data security failures.
The pattern emerging from this enforcement activity is instructive. Seven common privacy failures now routinely trigger enforcement: over-collection of personal data, unclear or bundled consent, weak vendor management, neglect of employee data protections, poor cross-border safeguards, treating privacy as a one-off project, and failing to industrialise data subject access request handling. Each of these is simultaneously a privacy compliance failure and a data governance failure — and none of them are solved by a firewall.
The Regulatory Complexity Explosion
The compliance landscape for privacy has become, in the bluntest possible terms, overwhelming — and it is getting worse.
The United States now has more than 20 comprehensive state privacy laws on the books, with no federal solution in sight. Organisations are spending 30–40% more on privacy compliance than in 2023, and the cost keeps climbing.
During 2025, several new comprehensive state privacy laws became effective in the US alone. These laws share common elements — consumer rights to access, delete, and opt out of certain processing — but vary significantly in applicability thresholds, definitions of sensitive data, consent standards, and requirements for data protection assessments. A national organisation cannot apply a single compliance template and call it done.
Globally, data protection authorities are gaining stronger enforcement powers, higher penalty ceilings, and broader definitions of personal and sensitive data. Regional data sovereignty and localisation rules are increasingly prescriptive, affecting cloud strategy and vendor selection for any organisation operating across borders.
For GRC teams already managing cybersecurity frameworks, sector-specific regulations, and operational risk programs, this expansion of privacy law is not an addendum — it is a major workstream in its own right, demanding specialist expertise that most security-focused GRC functions do not yet have.
Where GRC Sits in the Middle
The natural response to growing complexity is to assign data security to the security team and data privacy to the legal team, and hope the two talk to each other. In most organisations, that is more or less what happens. It rarely works well.
Privacy cannot remain a standalone legal function. Regulators expect organisations to show how policies map to real controls, how incidents are detected and managed, and how rights requests and assessments rely on actual data discovery and classification. This is driving closer collaboration between IT security, GRC, legal, and privacy stakeholders.
GRC is the function best positioned to make that integration work. It already sits at the intersection of policy, control, and evidence. The challenge is that traditional GRC frameworks were built primarily around security and compliance frameworks — ISO 27001, NIST, PCI-DSS — and often lack the native vocabulary for privacy governance: lawful basis, data subject rights, consent lifecycle management, privacy impact assessments, and retention schedules.
Privacy compliance remains one of the most critical and closely scrutinised areas of enterprise risk management. According to PwC’s Global Compliance Study 2025, 82% of companies plan to invest more in technology to drive compliance activities, with cybersecurity and data protection identified among the top compliance risk priorities.
The investment intention is there. The structural integration, in most organisations, is not.
The Data Governance Foundation
Both data security and data privacy depend on something that many organisations still lack: a comprehensive, accurate, and current understanding of what data they hold, where it is, how it flows, and who can access it. Without that foundation, security controls are applied inconsistently, privacy assessments rest on assumptions, and audit responses become exercises in retrospective reconstruction.
When looking to introduce or improve a legal GRC strategy, creating a data inventory is key — determining where the data is, who owns it and has access to it (including third parties such as vendors), whether their certifications are commensurate with their access, and which regulations apply.

This is unglamorous work. It does not generate the kind of visible security wins that drive budget conversations, and it lacks the urgency of a breach response. But it is the precondition for almost everything else. An organisation that cannot answer basic questions about its own data — where customer records are stored, how long they are retained, which third parties process them, and under what legal basis — cannot credibly demonstrate compliance with either security standards or privacy law.
Enterprises are moving away from separate point tools for data subject access requests, records of processing activities, data loss prevention, and incident response. They are looking for integrated platforms that orchestrate privacy workflows, map them to regulatory requirements, and consume data-layer intelligence from security controls — so they can demonstrate compliance consistently across multiple jurisdictions.
The AI Complication
The tension between security and privacy is being sharpened by the rapid deployment of AI systems throughout organisations. AI introduces a set of data governance challenges that cut across both domains simultaneously — and that most GRC frameworks are not yet equipped to handle.
From a security perspective, AI systems introduce new attack surfaces, model integrity risks, and data pipeline vulnerabilities. From a privacy perspective, they raise questions about the lawfulness of training data, the transparency of automated decision-making, and the rights of individuals whose data has been used to train models they may never have consented to.
New AI regulations, including the EU AI Act, are tightly linked to data protection obligations. How enterprises train, deploy, and monitor AI systems is becoming a privacy question as much as a security one.
For GRC leaders, this means that AI governance cannot be treated as a separate workstream. It must be integrated into the same framework that governs data security and privacy — with clear policies on training data sourcing, model documentation, access controls, and the rights of affected individuals.
What Good Integration Looks Like
Organisations that have made meaningful progress in integrating data security and privacy within their GRC programs tend to share a few characteristics.
They have moved away from treating privacy as a legal checkbox exercised at the point of a new product launch or data breach, and toward continuous privacy risk assessment embedded in change management and procurement processes. Privacy by design — embedding privacy considerations into information systems and business practices from the outset — is increasingly a regulatory expectation rather than an aspiration, particularly under GDPR’s requirement for data protection by default and by design.
They have built clear ownership at the intersection of security and privacy. The CISO understands that technical controls must map to privacy outcomes, not just security outcomes. The Data Protection Officer or privacy counsel understands that their regulatory obligations cannot be met without operational input from security, IT, and GRC.
And they have invested in the data foundation: the inventory, the classification scheme, the records of processing activity, and the vendor due diligence processes that make everything else auditable.
In 2026, privacy and data protection have become visible indicators of trust — and resilience is assessed by an organisation’s ability to continue operating through disruption, not simply recover after the fact.
The Bottom Line
Data security keeps bad actors out. Data privacy ensures you are doing the right thing with what you have. Both matter. Both have regulatory teeth. And neither can substitute for the other.
GRC professionals who understand both disciplines — who can translate the technical language of security controls into the rights-based vocabulary of privacy law, and back again — are among the most valuable people in the field right now. The organisations that invest in building that capability, rather than leaving security and privacy in separate silos hoping they will align at audit time, will be the ones that navigate the next wave of regulatory enforcement with confidence
