How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- OneTrust is the enterprise default for full privacy programs, but its modular pricing means costs stack as you add consent, DSAR and vendor risk modules.
- Mid-market teams should compare DataGrail, Osano and Transcend: all three automate the painful work of data mapping and subject requests without enterprise sales cycles.
- If cookie consent is the whole job, Cookiebot (free for sites up to 50 subpages, per its own site) or Osano's free tier solve it without a platform purchase.
- WireWheel was acquired by Osano, so evaluate the combined offering rather than treating them as separate vendors.

The best GDPR software
GDPR compliance is not a banner on your website. It is knowing what personal data you hold, where it lives, who you share it with, and proving you can delete it on request. Privacy software automates the parts humans cannot do at scale: data mapping, consent records, subject requests and vendor tracking. Eight platforms across the maturity curve.

OneTrust is the platform most enterprises buy when privacy becomes a board-level program. Its modules cover data mapping, assessments, consent and preferences, subject rights requests, vendor risk and incident response, now extending into AI governance. The DataGuidance regulatory content keeps legal teams current across jurisdictions.
The cost structure is the conversation. Modules are priced separately, so the "platform" price grows with each capability you add, and implementations typically involve services. Smaller companies will find it more than they need. OneTrust fits large organizations that want one vendor for the entire privacy and governance program.
What we like- Broadest module coverage from consent to AI governance
- Strong regulatory intelligence content
- Proven at the largest global enterprises
Watch out for- Modular pricing stacks up fast
- Implementation is heavy and consultant-assisted

DataGrail focuses on the two jobs mid-market privacy teams dread: keeping the data map current and fulfilling subject requests. Its integration library connects to the SaaS apps where personal data actually lives, so the record of processing stays accurate without manual spreadsheets, and the request manager automates verification and fulfillment.
It is narrower than OneTrust by design. If you need full GRC, ethics and ESG alongside privacy, look elsewhere. DataGrail suits growth-stage companies that need credible GDPR and CCPA operations quickly, with engineering-light deployment.
What we like- Nearly 2,000 prebuilt integrations keep the data map live automatically
- Purpose-built DSR automation
- Faster to deploy than enterprise suites
Watch out for- Depth beyond DSR and mapping is thinner
- Pricing is quote-based with no public entry point

Osano
Best for: Approachable privacy for growing companies

Free planYes
Osano grew from the world's most deployed cookie consent tool into a full privacy platform. It now covers consent management, vendor risk monitoring, data mapping and subject rights in one interface designed for teams without dedicated privacy engineers. The free tier handles basic consent needs, which makes starting frictionless.
Large enterprises with complex data estates will find the discovery and governance depth lighter than the enterprise suites. Osano's acquisition of WireWheel added preference management strength. Osano fits mid-size companies that want one approachable vendor for the whole privacy program.
What we like- Free tier covers basic cookie consent
- Unified platform from consent to subject rights
- B Corp positioning resonates with values-driven buyers
Watch out for- Enterprise depth trails OneTrust and Securiti
- Advanced data discovery is lighter

Transcend treats privacy as infrastructure. Its platform fulfills access and deletion requests programmatically across your systems and vendors through APIs, rather than routing tickets to humans. The consent management and data inventory pieces follow the same philosophy: code-driven, automated, auditable.
That design assumes engineers are in the loop. Privacy teams without development resources will move slower here than on a no-code platform. Transcend suits tech companies with engineering capacity that want privacy operations embedded in systems rather than bolted on as process.
What we like- API-first design fits engineering-led organizations
- Privacy requests execute against live systems, not tickets
- Strong documentation for custom builds
Watch out for- Requires engineering involvement to get full value
- Less hand-holding for non-technical privacy teams

Securiti approaches privacy from the data side: discover and classify sensitive data across cloud and on-premises systems, then run privacy workflows on that foundation. The same intelligence powers data security posture management, making it attractive to CISOs and DPOs who want one data intelligence layer serving both security and compliance.
The breadth is also the cost. Evaluations take longer, implementations touch more systems, and pricing reflects the enterprise positioning. Securiti fits large organizations where privacy, security and data governance are converging under one mandate.
What we like- Unifies data security posture with privacy operations
- Deep discovery and classification
- AI governance modules for the new regulatory wave
Watch out for- Platform breadth means longer evaluations and implementations
- Pricing is enterprise-grade

TrustArc brings the longest history in the group, evolving from TRUSTe certifications into a full privacy management platform. Its strength is programmatic: assessments, cookie consent, data mapping and subject requests guided by methodology refined over decades. The certification heritage still carries weight with partners and customers doing diligence.
Newer competitors move faster on automation and developer experience. TrustArc suits organizations that value proven methodology and third-party certification signals, particularly those with long-standing privacy programs rather than greenfield builds.
What we like- Decades of privacy program methodology built in
- TRUSTe certifications add third-party credibility
- Strong in assessments and cookie compliance
Watch out for- Interface and pace of innovation trail newer API-first rivals
- Pricing is quote-based

Cookiebot, part of Usercentrics since the 2021 acquisition, does one thing exceptionally well: cookie consent. Its scanner finds and categorizes the trackers on your site automatically, the banner handles GDPR, ePrivacy and CCPA requirements, and Google certification keeps Consent Mode working for advertisers. The free tier covers small sites up to 50 subpages, per the company's own site.
It is not a privacy platform. Data mapping, DSRs and vendor risk live elsewhere. Cookiebot fits businesses whose GDPR exposure is primarily the website: publishers, marketers, SMBs and anyone who needs compliant consent without buying a suite.
What we like- Patented scanner auto-detects cookies and trackers
- Free tier for sites up to 50 subpages
- Google-certified for Consent Mode
Watch out for- It solves consent, not the wider privacy program
- Larger sites move to paid tiers quickly

WireWheel built its reputation on preference management and privacy operations for complex enterprises, with strengths in consent orchestration and data inventory. Its acquisition by Osano means new buyers should evaluate the combined offering and roadmap rather than the product as it existed standalone.
For existing WireWheel customers the question is migration path; for new buyers the question is whether the Osano platform now covers the need directly. Listed here for completeness since the brand still appears in evaluations, but shortlist Osano and ask how WireWheel's capabilities carry forward.
What we like- Strong preference and consent management for complex programs
- Enterprise-grade data governance features
- Now backed by Osano's platform
Watch out for- Acquired by Osano, so evaluate the combined roadmap, not the standalone product
- Standalone pricing is enterprise-level
What to check before you buy
Scope the actual legal obligation first. A marketing site needs consent management; a SaaS company holding customer data needs mapping, DSR automation and vendor tracking; a global enterprise needs all of it plus assessments and AI governance. Buying a platform for a banner problem wastes a year.
Then verify the integration reality. Data mapping is only as good as its connectors: check that your actual systems (the CRM, warehouse, marketing tools and databases you run) are covered, not just the logo wall. Test DSR fulfillment end to end during evaluation, since that workflow is where weak products collapse. Finally, confirm who operates the tool day to day: engineering-led platforms need engineers, and methodology-heavy platforms need privacy staff.
How we chose
We selected privacy platforms with live GDPR-relevant products and real customer bases, from consent specialists to enterprise suites, using vendor documentation, pricing pages and public reviews. We list starting prices as See website where we could not verify a current figure on the vendor's own pricing page. We did not conduct legal reviews or test DSR fulfillment.
Data mapping: the unglamorous foundation
Every GDPR program rests on a data map: what personal data you hold, where it came from, where it lives, who can access it and when it gets deleted. It is tedious work, and skipping it makes everything else theater. You cannot fulfill a deletion request for data you do not know you have.
Start with the obvious systems (CRM, marketing platform, support desk, HR) and then hunt the shadows: spreadsheets with customer lists, the analytics tool nobody remembers installing, backups, the founder's laptop. Shadow data is where breaches and failed DSARs come from.
For each data store, record the lawful basis, the retention period and the deletion method. "We keep it forever just in case" is not a retention policy. Tie retention to purpose: marketing consents last until withdrawn, transaction records last as long as tax law requires, and everything else should have an expiry.
Review the map twice a year. Systems change constantly; the map decays fast. Assign an owner per system (usually the team that uses it) and make the review part of an existing cycle. A data map is a living document or it is fiction.
Frequently asked questions
Is a cookie banner enough for GDPR compliance?
No. Consent is one requirement among many. You also need records of processing, data subject request handling, vendor agreements, breach procedures and security measures. A banner without the program behind it is decoration.
What is a data subject request (DSR)?
It is a request from an individual to access, correct, delete or port their personal data. GDPR gives individuals these rights, and companies must respond within strict timelines. Automation matters because manual fulfillment does not scale.
How much does GDPR software cost?
Cookie consent tools start free for small sites. Mid-market privacy platforms are quote-based but typically run to tens of thousands annually. Enterprise suites cost far more once modules stack. Always get the modular quote in writing.
Do US companies need GDPR software?
If you process personal data of people in the EU or UK, yes, regardless of where your company sits. Many US companies also face CCPA and state privacy laws, which these same platforms cover.
What is the difference between consent management and a privacy platform?
Consent management handles website and app permission banners. A privacy platform adds data mapping, subject requests, vendor risk, assessments and governance. Most companies need the first immediately and grow into the second.
Can these tools replace a privacy lawyer?
No. Software automates operations; it does not give legal advice. You still need counsel for interpretation, DPIAs and regulatory strategy. The tools make the lawyer's program executable.
