DataTrue – is a great complement to OneTrust and BigID for privacy engineers who want real time privacy checking and auditing of consent, providing proof of due diligence.
While at the 2025 IAPP conference recently in San Diego there were several privacy compliance vendors, possibly the two most well known were OneTrust and BigID, and since these two vendors are appearing also at the 2025 ANZ IAPP conference in Sydney its helpful to set out how they compare and where DataTrue contrasts and complements these Privacy Compliance market leaders.
In today’s digital landscape, where data privacy regulations are becoming increasingly stringent, larger enterprises must prioritize their online privacy practices. One crucial aspect of this is conducting real time tag and cookie checks to ensure they are in line with the privacy policy consent level agreed with your customers, and DataTrue offers a powerful solution to streamline this process when using OneTrust, BigID, or similar platforms.
OneTrust and BigID are enterprise-grade data privacy compliance platforms with wide adoption, but they have distinct focuses and features compared to DataTrue. Below is a detailed feature comparison with clear differences:
OneTrust vs BigID: Feature Overview
- OneTrust:
* Extensive privacy, risk, and compliance management platform.
* Core strengths: privacy governance, data mapping, consent and preference management, DPIAs, cookie compliance, vendor risk, ESG, and audit tools.
* Deep integrations and modules for GRC, ethics, and sustainability.
* Survey-based and API-driven data inventories.
* Supports global privacy law compliance (GDPR, CCPA, etc.).
* Heavy enterprise focus; noted for complex setup and long contracts. (Refer captain compliance) - BigID:
* Data-centric platform with machine learning-powered discovery, classification, and automated governance of personal and sensitive data.
* Key focus: Identity-centric, AI-powered data discovery across cloud, on-premise, and hybrid environments.
* Excels in automated DSAR (data subject access request), records of processing activities (RoPA), and RoPA+ (for mapping processing to actual discovered data).
* Emphasizes data protection, lifecycle management, and proactive risk identification.
* Slightly narrower in regulatory coverage but offers deeper analytics and automation in data discovery.(Refer enzuzo) - DataTrue:
* Specializes in automated testing and monitoring of data collection (cookies, tags, tracking pixels) on websites and apps.
* Key features: continuous tag/cookie monitoring, automated cookie audits, real-time privacy leak detection for PII, and validation of consent policy adherence.
* AI-driven leak alerts and customizable workflows for privacy risk prevention.
* Easy integration into web/app development pipelines to ensure ongoing compliance as sites and apps update.
* Integration support with other platforms, including OneTrust, for holistic privacy reporting and quality assurance.(Refer Datatrue)

Key Differences
- OneTrust and BigID are deep, enterprise privacy governance platforms, while DataTrue is laser-focused on ensuring that all digital data collection complies with privacy and consent policies in real time.(Refer Datatrue).
- DataTrue’s unique positioning is in automated validation, monitoring, and leak detection—making it especially valuable for businesses looking to monitor analytics and consent enforcement without deploying full-scale GRC solutions.(Refer here).
- OneTrust and BigID excel in audits, legal workflows, data mapping, DPIA, DSAR, and regulatory coverage on a global scale, while DataTrue provides practical, easy-to-integrate solutions for digital assurance and ongoing compliance monitoring, including real-time tracking of PII leaks.(Refer capterra).
This makes DataTrue a strong complement or alternative for organizations with substantial digital assets, dynamic marketing, or high-volume tag/cookie changes, or those that need practical tools to check consent and minimize data leakage risk on a continuous basis.
Competitive Positioning – DataTrue vs. BigID vs. OneTrust
| Capability Area | DataTrue | BigID Consent | OneTrust Cookie Consent | DataTrue Advantage |
| Primary Focus |
✅ Quality assurance + compliance testing – Continuous validation that consent mechanisms work as intended – Technical verification of implementation |
🔵 Discovery + consent banner deployment – Cookie inventory and CMP platform – IAB/Google certified framework |
🔵 Consent platform + preference management – Banner creation and deployment – 45M+ cookie database |
Testing-First Philosophy: DataTrue validates that OTHER platforms (including BigID/OneTrust banners) actually work correctly |
| Consent Validation Testing |
✅ Core capability – Tests if tags fire before consent – Verifies banner blocking functionality – QA testing in dev environments – Consent manager error detection |
⚠️ Limited testing capability – Focuses on scanner classification – Relies on automatic categorization – Manual verification needed |
⚠️ Limited testing capability – Banner deployment and management – A/B testing for opt-in rates – No automated blocking verification |
DataTrue catches configuration errors that lead to fines (Honda $632K, Todd Snyder $345K) – testing that banners actually block tags, not just deploying banners |
| Third-Party Tag Monitoring |
✅ Advanced detection – Identifies unauthorized pixels – Detects session replay tools
– Search term sharing audits |
🔵 Discovery-focused – Identifies cookies, beacons, scripts – Classification by type – Vendor identification |
🔵 Database-driven categorization – Pre-categorized cookie library – Vendor information – Purpose grouping |
DataTrue monitors actual behavior (what data moves where) vs. just identifying what’s present – critical for Healthline-type violations ($1.55M for unexpected SPI sharing) |
| GPC Signal Compliance |
✅ Active testing – Simulates GPC signals – Validates banner response – Tests opt-out enforcement – Regional GPC testing |
🔵 Framework support – GPC integration capability – IAB TCF v2.2 certified – Google Consent Mode v2 support |
🔵 Geolocation rules – Regional banner variation – State-level consent models – 250+ language support |
DataTrue tests if GPC actually works – Tractor Supply paid $1.35M for failing to honor GPC; DataTrue prevents this with automated testing |
