Data mapping and Records of Processing Activities (ROPA) automation
Data Subject Access Request (DSAR) workflow and fulfillment automation
Data Protection Impact Assessment (DPIA) templates and workflows
Breach detection and 72-hour notification management
Vendor and third-party risk assessment for data processors
Integration with your website, CRM, and marketing tools

Where PoliWriter Fits
PoliWriter serves as the documentation layer of your GDPR compliance program. While platforms like OneTrust and Cookiebot handle consent management and technical controls, PoliWriter generates the written policies and legal documents your program requires — privacy notices, data processing agreements, data protection impact assessment templates, records of processing activities, and internal data handling policies. Many organizations spend thousands on consultants or law firms to draft these documents. PoliWriter produces customized, audit-ready GDPR documentation at a fraction of that cost, complementing whatever technical privacy tools you already use.
Frequently Asked Questions
What is the best GDPR compliance software for small businesses?
For small businesses, Osano ($199/month) offers a good balance of features and affordability, while Cookiebot provides a free tier for cookie consent on smaller websites. PoliWriter ($49/month) is the most affordable option for generating GDPR policies and documentation. The right choice depends on whether you primarily need consent management, data mapping, or policy documentation.
Is a cookie consent banner enough for GDPR compliance?
No. Cookie consent is just one requirement of GDPR. Full compliance also requires a privacy notice, records of processing activities, data subject access request processes, data processing agreements with vendors, data protection impact assessments for high-risk processing, and breach notification procedures. Cookie tools like Cookiebot handle one piece of the puzzle.
How much does GDPR compliance software cost?
Costs vary dramatically. Cookie consent tools start at $12/month. Mid-market privacy platforms like Osano cost $199-$999/month. Enterprise platforms like OneTrust and BigID can cost $15,000-$200,000+/year. Policy generation tools like PoliWriter start at $49/month. Your total cost depends on your organization size, data volume, and which compliance activities you need to automate.
Do I need OneTrust for GDPR compliance?
OneTrust is the most comprehensive option but is overkill for most small and mid-size organizations. You only need OneTrust if you are managing privacy compliance across multiple jurisdictions with complex data processing operations. Smaller organizations can achieve GDPR compliance with a combination of a consent tool (Cookiebot or Osano), a policy generator (PoliWriter), and internal processes for DSARs and breach response.
Can I handle GDPR compliance without software?
Technically yes, but it is extremely difficult and risky. You would need to manually create and maintain policies, track consent records, manage DSARs with spreadsheets, and conduct DPIAs without templates. For very small businesses processing minimal personal data, this might be feasible. For any organization of meaningful size, software dramatically reduces the risk of missing requirements and facing fines of up to 4% of global annual revenue.
What is the difference between a CMP and a privacy management platform?
A Consent Management Platform (CMP) like Cookiebot focuses specifically on managing cookie consent and tracking on websites. A privacy management platform like OneTrust or TrustArc covers the full range of privacy operations including data mapping, DSARs, DPIAs, vendor management, and consent. CMPs solve one problem well; privacy platforms aim to be comprehensive but cost significantly more.
Does PoliWriter replace OneTrust or Cookiebot?
No. PoliWriter complements these tools. Cookiebot manages your cookie consent banners, OneTrust handles consent, DSARs, and data mapping, and PoliWriter generates the policy documents and legal notices that your privacy program requires. Many organizations use PoliWriter alongside their technical privacy tools to handle the documentation layer affordably.
