The best GDPR compliance software depends on your size. Enterprises with a privacy team need a broad platform like OneTrust or TrustArc. Small and mid-sized SaaS companies usually get more done with a focused tool that handles the day-to-day work: consent, data subject requests, DPAs and vendor records.
We make ComplyDog, so we're one of the tools on this list. We've tried to be fair about where each tool fits, including where ComplyDog is not the right choice. Pricing and features were checked on each vendor's own website in November 2026 and can change, so confirm before you buy.

What GDPR compliance software should actually do
GDPR is mostly ongoing operational work, not a one-off project. Good software takes that work off your plate. Look for these five things:
- Consent management. A cookie banner that blocks non-essential scripts until the visitor agrees, stores proof of consent, and supports Google Consent Mode v2.
- Data subject requests. A way to receive, verify, track and answer access and deletion requests within the one-month deadline in Article 12.
- Records of processing. The Article 30 record of what data you process, why, and who you share it with.
- Vendor and DPA management. A list of your subprocessors and signed data processing agreements under Article 28.
- Evidence. An audit trail you can show a customer's security review or a regulator.
If a tool only does some of these, you'll need others to cover the rest. That's fine, as long as you know it going in.
How we picked
We compared tools on coverage of the five jobs above, how long setup takes without a consultant, who the product is built for, and how open the pricing is. We left out pure data governance and security tools such as Collibra, BigID and Microsoft Purview. They are strong products, but they solve a different problem from GDPR compliance for most companies.
The 8 tools
1. ComplyDog: best for SaaS and small teams
ComplyDog is built for companies that need to be GDPR compliant but don't have a privacy department. It gives you a compliance portal on your own domain where customers can submit access, deletion and correction requests, request and e-sign your DPA through DocuSign or Dropbox Sign, and see your current subprocessor list. It also includes a cookie consent banner and a security page for customer reviews. Setup takes about 30 minutes.
- Good fit if: you're a SaaS or SMB team, you get DPA and data requests from customers, and you want published pricing.
- Not the best fit if: you need data mapping, records of processing or custom workflows across dozens of privacy laws and business units. OneTrust, TrustArc or DataGrail will suit you better.
- Pricing: Solo $49/month, Teams $99/month, Agency $199/month. 14-day free trial, no credit card needed.

2. OneTrust: best for large enterprises
OneTrust is the broadest privacy platform on the market, covering consent, DSARs, data mapping, vendor risk and assessments across many jurisdictions.
- Good fit if: you have a dedicated privacy team and complex, multi-country requirements.
- Not the best fit if: you're a small team. Pricing is quote-based on annual contracts, and setup and ongoing management usually need dedicated staff.
Comparing the two? See ComplyDog vs OneTrust.
3. TrustArc: best for assessments and certification
TrustArc pairs a governance suite (PrivacyCentral, data mapping and an assessment manager for PIAs and DPIAs) with consent and data subject rights tools. It also runs the TRUSTe certification programs.
- Good fit if: you want structured assessments and an external certification to show customers.
- Not the best fit if: your main need is a cookie banner and request handling. Pricing is by quote only.
4. Osano: best mid-market all-rounder
Osano combines cookie consent with data subject request handling, vendor privacy risk monitoring, data mapping and assessments.
- Good fit if: you're mid-sized and want consent and requests from one vendor, with room to grow into a fuller privacy program.
- Not the best fit if: you need more than consent on a small budget. The free plan covers cookie consent only, and the privacy program plans are quote-based.
5. Usercentrics (Cookiebot): best for consent only
Usercentrics, which owns Cookiebot, specializes in consent management. Cookiebot scans your site, categorizes trackers and supports Google Consent Mode and the IAB TCF. It has a free plan for one small site, and paid plans priced by the number of pages.
- Good fit if: consent is your only gap.
- Not the best fit if: you also need DSARs, DPAs and records. You'll need another tool for those.
6. iubenda: best for policies on a small budget
iubenda is known for its privacy and cookie policy generator, with a cookie banner and consent records alongside. Plans are priced per site and by pageviews.
- Good fit if: you run a small site and mainly need policies and a banner.
- Not the best fit if: you handle regular DSARs or B2B customer security reviews. The DSAR tool is only in the top plan.
7. DataGrail: best for automating requests across many systems
DataGrail automates data subject requests by connecting to the systems where personal data lives, with hundreds of integrations. Its Live Data Map keeps a system inventory and generates records of processing.
- Good fit if: you get a high volume of requests across many SaaS tools.
- Not the best fit if: you get a handful of requests a year. Pricing is by quote.
8. Vanta: best if you also need SOC 2
Vanta is a security compliance automation platform for SOC 2, ISO 27001 and others. Its GDPR product adds a data inventory, records of processing, DPIAs and automated evidence collection.
- Good fit if: SOC 2 or ISO 27001 is your main goal and GDPR comes second.
- Not the best fit if: GDPR is your priority. Vanta doesn't provide a cookie banner or a customer-facing request process, so you'll still need those. See ComplyDog vs Vanta.
How to choose
- Under 50 people, no privacy team: a focused tool such as ComplyDog, or iubenda if you only need policies.
- Consent is the only gap: Usercentrics or Cookiebot.
- High request volume across many systems: DataGrail or Osano.
- Enterprise, many jurisdictions: OneTrust or TrustArc.
- SOC 2 first: Vanta, plus a consent and DSAR tool.
FAQ
Do I need GDPR compliance software?
No law requires software. But if you have EU users, you need a lawful cookie banner, a way to answer data subject access requests within a month, records of processing and DPAs with your vendors. Software is usually cheaper than doing all of that by hand.
What is the cheapest way to become GDPR compliant?
Start with a free cookie banner and checker, then add DSAR and DPA tooling as requests and customer reviews come in. Try our free cookie consent banner and cookie checker.
Is a cookie banner enough for GDPR?
No. A banner covers consent for cookies under the ePrivacy rules. GDPR also covers how you handle requests, document processing, manage vendors and report breaches. Read our guide to GDPR cookie consent banners for what a banner itself must do.
Does GDPR software make me compliant automatically?
No tool does. Software handles the repeatable work and keeps evidence, but you still decide your lawful basis for each purpose and keep your records accurate.
