16 Best GDPR Compliance Companies in Europe (2026)

At Gilzor, we develop custom software for companies operating in Europe, with GDPR requirements considered during product planning, design, development, testing, and ongoing support. Our work covers web and mobile applications that collect or process personal information, including customer accounts, contact forms, internal tools, payment-related workflows, and user-facing platforms. We look at what data the product needs, where it is stored, who can access it, and how unnecessary collection can be avoided.

GDPR compliance is handled as part of the software itself. We can build consent controls, privacy settings, access permissions, data deletion workflows, and processes for responding to user requests. Our team also reviews security and performance risks during quality assurance.

DPO Europe provides GDPR and data privacy support to companies operating in Europe and across several international markets. They combine consulting, staff training, outsourced Data Protection Officer services, and compliance tools within one service model. Their work also covers privacy rules outside the EU, which can be useful for businesses handling personal data across several regions.

Alongside GDPR support, they help organisations prepare for the EU AI Act and build internal processes for responsible AI use. DPO Europe also assists with audits, compliance checks, privacy documentation, and long-term workflows rather than treating compliance as a one-time review.

Obelis provides GDPR consultancy with a clear focus on medical devices and other regulated products in Europe. They help companies understand whether they act as data controllers or processors, choose lawful grounds for processing, and handle personal data in line with EU and EEA requirements.

Their approach connects GDPR work with quality management and regulatory processes such as MDR and IVDR compliance. This matters when personal data appears in clinical evaluations, customer feedback, post-market surveillance, or connected medical technology. Obelis also helps companies review applicable privacy laws and update internal compliance processes as regulations change.

Crowe offers ongoing GDPR compliance monitoring for companies in Europe, including organisations that do not have an internal Data Protection Officer. They also support in-house DPOs who need help following legal changes, deadlines, and recurring privacy obligations. Rather than relying only on periodic audits, Crowe tracks updates that may affect each client's business area.

The service includes reminders, notifications, internal training, and records of GDPR-related tasks and risks. Crowe can also assist with technical and organisational controls, privacy documentation, data subject requests, regulatory inspections, and the use of GDPR rules within IT systems.

Glocert International delivers independent GDPR assessments for organisations working in Europe or processing the personal data of EU residents. They review how data is collected, stored, used, shared, and deleted, then compare those processes with the main requirements of the regulation. The service is also available to companies based outside the EU when their products or services fall within the GDPR's reach.

Their process starts with defining the scope of compliance and mapping personal data across the organisation. Glocert International then carries out a gap assessment, reviews privacy documents, supports corrective work, and completes an independent assessment of the organisation's compliance position.

IRM Consulting supports businesses with GDPR compliance, data management, and information governance. They assess current processes, identify compliance gaps, and create an action plan based on how the organisation actually handles personal data.

Their work covers privacy notices, internal policies, data retention, records of processing activities, and procedures for responding to subject access requests. IRM Consulting can also help implement encryption, access controls, secure document storage, and monitoring measures. Once the main changes are in place, they review the outcome and identify areas that still need attention. This gives companies a more structured way to maintain GDPR compliance rather than relying on a single audit.

UnderDefense connects GDPR compliance with day-to-day security operations. They use continuous monitoring, managed detection and response, and incident handling to produce evidence that technical controls are actually working. This supports requirements around secure data processing, breach response, and privacy risk assessment without relying only on policy documents.

Their platform brings security data from different tools into one compliance record, which can make audit preparation less manual. UnderDefense also helps companies document incident response steps, maintain evidence for regulatory reviews, and support breach notification workflows.

Oski Solutions provides software development, security, and compliance services for companies operating in Europe. They build GDPR controls into the design, development, and operation of digital systems, rather than treating compliance as a separate task after launch.

Access management, encryption, audit logging, vulnerability testing, and real-time monitoring form the technical side of their GDPR work. Oski Solutions can also review gaps in existing systems and introduce clearer security policies across teams. Their approach fits companies that need both product development and stronger control over how sensitive data is accessed and protected.

FTI Consulting supports organisations with complex GDPR programmes that involve legal, IT, compliance, HR, and business teams. They assess how the regulation applies, identify gaps across people, processes, and technology, and turn the findings into a practical action plan.

The scope can extend from data mapping and subject access requests to employee training, privacy impact assessments, contract reviews, and cybersecurity controls. FTI Consulting also works on breach preparation, sensitive data cleanup, and independent audits of existing GDPR programmes. This makes their service suitable for larger or multinational organisations where personal data moves through many systems and departments.

DataGuard combines GDPR consultancy with a platform for managing privacy tasks. They support companies in Europe with compliance reviews, gap assessments, policy implementation, and ongoing monitoring. Consultants from legal and IT backgrounds work with internal teams to define an acceptable privacy risk level and organise the steps needed to reduce compliance gaps.

The platform keeps audits, incidents, data mapping, risk assessments, and subject requests in one place. DataGuard also provides outsourced DPO support, breach assistance, cookie management, and consent tracking. Companies can use the consulting service for interpretation and planning while the software handles much of the documentation and follow-up work.

DocuWare offers document management and workflow automation software that can support GDPR compliance for organisations in Europe. They focus on the personal data stored in emails, contracts, scanned files, and other structured or unstructured documents. Their system helps teams find this information, control access to it, and manage how long it remains in storage.

Document-based requests can be handled through search, export, correction, restriction, and deletion functions. DocuWare can also support the right to erasure by helping organisations remove personal information from managed records when there is no lawful reason to retain it. Paper files are part of the same compliance problem, so digitisation and controlled document workflows can make records easier to track than disconnected filing cabinets and shared folders.

DPO Consulting works directly with organisations that need to establish or maintain GDPR compliance in Europe. They begin by reviewing the existing privacy programme, identifying gaps, and preparing an action plan based on the organisation's structure, industry, and data processing activities. The service can cover a single compliance issue or an ongoing external privacy function.

For companies without an internal privacy team, DPO Consulting provides outsourced DPO support and representation in the EU or UK. They also handle impact assessments, employee training, documentation, and regulatory monitoring. Their myDPO software gives internal teams a place to organise compliance tasks and follow progress, which is more manageable than tracking every obligation through separate spreadsheets and email threads.

A-LIGN provides GDPR audit and advisory services for organisations that process the personal data of people in Europe. They work with companies at different stages, from early readiness checks to formal gap assessments and ongoing compliance work. Their process looks at how personal data enters the organisation, where it is stored, how it is used, and when it should be deleted.

A-LIGN also uses its A-SCEND platform to organise audit requests, documents, and review steps in one place. Workshops can help internal teams understand GDPR terms and responsibilities before deeper assessment begins. For businesses working across several regulatory frameworks, they can connect GDPR work with broader privacy and security requirements rather than running each review separately.

Deloitte supports GDPR compliance through a multidisciplinary team covering law, process management, technology, and information security. Their Czech and Slovak consulting practice works with organisations that need to understand how privacy requirements affect internal documents, business processes, and IT systems. They can review an existing compliance setup or help build one where responsibilities and controls are still fragmented.

Technology changes can quickly make older procedures less useful, especially when new systems or data sources are introduced. Deloitte helps companies update GDPR programmes, review regulatory and reputational risks, and bring compliance tasks into more organised digital workflows. Their involvement can cover policy-level decisions as well as the way personal data is protected inside operational systems.

SecurityWall offers GDPR compliance and cybersecurity services for organisations operating in Europe or processing the personal data of EU residents. They assess consent practices, privacy notices, internal records, data subject procedures, and the technical controls used to protect information.

Beyond the initial assessment, SecurityWall supports policy development, staff training, DPO responsibilities, and recurring compliance audits. Their dashboard can be used to track unresolved gaps and monitor progress over time. Since the company also works in penetration testing, cloud security, and digital forensics, they can examine whether documented privacy controls are supported by the actual security setup.

PwC advises organisations on how GDPR affects the collection, use, transfer, retention, and deletion of personal data. Their support is aimed at companies based in Europe as well as businesses elsewhere that sell to European customers or monitor the online activity of people in the region. They work with both controllers and processors that need to understand their responsibilities and show that privacy obligations are being managed across the organisation.

The work can involve reviewing governance, operating processes, data handling practices, and the systems used to respond to individual rights requests. PwC can also help organisations build a more consistent privacy programme, clarify accountability, and prepare evidence for regulators. Their broader risk and technology capabilities allow GDPR requirements to be considered alongside digital transformation and regulatory change.
