Integration and technical compatibility:
Sirdata is a French company specializing in personal data compliance and digital tracking performance. Its product suite covers three main areas: consent management via a CMP (Consent Management Platform), server-side tracking via GTM Server Side, and audience analysis in compliance with the GDPR. The entire platform is hosted on 100% European infrastructure.
The CMP ABconsent is the platform’s flagship product. It allows you to deploy a consent banner that complies with the GDPR, ePrivacy, and CCPA on any website in just a few minutes, without requiring advanced technical knowledge. The CMP manages processing purposes by category, automatically blocks third-party scripts until consent is obtained, and ensures the transmission of consent signals via TCF 2.2 (IAB Europe’s Transparency & Consent Framework). It supports over 16 languages, automatically adapts to applicable regulations based on the visitor’s geolocation, and is compatible with all major CMS environments (WordPress, Shopify, etc.) as well as Google Tag Manager.
CMP natively supports Google Consent Mode V2, which means that Google tags (Analytics, Ads, Floodlight) adapt their behavior based on user preferences, allowing for partial measurement through conversion modeling even in cases of opt-out. Integration with Microsoft Clarity is also natively supported through the Sirdata interface.
Third-party script management is a core feature: without writing a single line of code, site administrators can make any script contingent on user consent, directly from the dashboard.
Server-Side GTM (sGTM) is the second pillar of the offering. It allows the execution of measurement and advertising tags to be moved from the user’s browser to a Sirdata server hosted in Europe. The benefits are numerous: improved website loading performance, bypassing ad blockers and browser ITP/ETP restrictions, extending the lifespan of first-party cookies, and better control over data transmitted to third-party partners. Sirdata has developed GTM-Helper, a proprietary overlay that automates several tasks: rewriting script URLs to bypass blockers, reordering the dataLayer, and batch loading the CMP and Consent Mode.
Sirdata Analytics Helper is a complementary tool that enables you to collect audience data even without consent, using a cookie-free method based on legitimate interest and pseudonymization. It integrates with Google Analytics 4 to provide compliant audience measurement without requiring explicit consent for the measurement purpose.
Finally, Sirdata offers audience- and context-based targeting solutions for advertisers and publishers, leveraging first-party data collected with consent.
Sirdata offers different pricing models depending on the product. Both CMP ABconsent and GTM Server Side are billed on a pay-as-you-go basis, with a sliding scale based on traffic volume. A 14-day free trial is available for both products, with no credit card required. A discount applies for annual subscriptions.

1️⃣ If you are a freelancer or consultant:
For an entrepreneur agency that deploys client websites and is looking for a consent solution that’s easy to integrate and maintain, Axeptio is a direct alternative—very popular in France—with a design-first approach and a user experience that boosts consent rates. It has a very low learning curve and an affordable pricing model. Cookiebot (now part of the Usercentrics ecosystem) is also widely used by agencies, featuring native integration with WordPress and automatic cookie scanning that simplifies the initial audit. Termly rounds out this overview for entrepreneurs English-language or international websites, offering a solution entrepreneurs combines a consent banner with automatic privacy policy generation.
2️⃣ If you are a startup:
Startups in the growth phase that are beginning to see significant traffic often need to go beyond a simple consent banner. Axeptio remains a valuable tool at this stage due to its ease of deployment and its integration with Google Consent Mode. For startups that want to directly address server-side tracking to improve their ad performance and audience measurement, solutions like Addingwell or Stape allow for simplified deployment of GTM Server Side without needing a third-party provider. These tools are less comprehensive than the Sirdata ecosystem but more technically accessible for early-stage teams.
3️⃣ If you are a small business or an SME:
At this level, GDPR compliance becomes a structured operational challenge. Axeptio’s Business version is designed for websites with moderate traffic volumes that require a customized consent experience. For SMEs whose marketing teams rely heavily on digital advertising and GA4, server-side tracking becomes critical: signal loss due to ad blockers and browser restrictions can directly impact campaign ROAS. In this case, Sirdata remains a market leader in France, particularly due to its European hosting and the team’s regulatory expertise. For organizations seeking an all-in-one compliance solution that also includes data subject rights management (DSARs), platforms like Didomi or OneTrust offer an additional layer of data governance that Sirdata does not natively cover.
Otherwise, these other software programs may also be a good alternative to Sirdata.
