CookieBeam is a self-serve consent engine with 5-layer script blocking, connection-level enforcement, and server-side depth. Here's how they compare for 2026 buyers. ## Enterprise Platform vs Self-Serve Engine Didomi is an enterprise consent and preference management platform, French-headquartered, and after a busy 2025 it's bigger than ever. In April 2025 it acquired Addingwell (server-side tracking infrastructure), and on July 8, 2025 it acquired Sourcepoint, a publisher-focused CMP with more than 200 enterprise customers. Both deals were backed by Marlin Equity Partners. So a 2026 evaluation of Didomi is really an evaluation of Didomi plus Sourcepoint plus Addingwell: consent, publisher messaging, and server-side under one roof. CookieBeam plays a different game. It's a self-serve consent platform you sign up for and configure yourself, with plan-based pricing with included sites and per-site add-ons, and it includes 5-layer script blocking, connection-level consent enforcement, server-side tagging, regional rules, and A/B testing without an enterprise contract. The question for a buyer is whether you need a large, omni-channel enterprise platform with preference management and CTV reach, or a transparent self-serve engine that covers the core consent job well. This guide lays out both. If you're comparing the biggest enterprise names, our [CookieBeam vs OneTrust](https://cookiebeam.com/guides/cookiebeam-vs-onetrust-comparison-2026) guide covers the other end of that market. ## What Didomi Brings At the enterprise end, Didomi is a serious platform, and its 2025 acquisitions widened it further. **Preference management, beyond consent.** Didomi goes past a cookie banner into full preference centers and user privacy journeys, letting large organizations manage granular choices across products and channels. That's a category above what most SMB tools attempt. **Omni-channel reach.** Consent experiences span web, mobile, in-app, and, especially after the Sourcepoint acquisition, OTT and connected TV, plus publisher messaging like subscription and consent walls. For a media company or a large advertiser, that breadth is the point. **Every major standard.** Didomi supports IAB TCF 2.2 (and tracks newer versions), the Global Privacy Platform (GPP), Google Consent Mode v2, Microsoft UET consent, and AWS consent mode, and it's a Google-certified Gold partner. It reports processing billions of consents a month. **Server-side, via Addingwell.** The Addingwell acquisition brought server-side tracking infrastructure into the fold, so Didomi can now speak to server-side tagging as well. Pricing is sales-led and not publicly listed. Plans are customized (Didomi markets tiers like Consent Essentials, Core Privacy UX, and Privacy UX Plus), and any dollar figures floating around third-party sites should be treated as unverified. Expect a quote and a contract. ## Where CookieBeam Is Different CookieBeam doesn't try to be an omni-channel preference platform. It focuses on doing web consent blocking and measurement well, self-serve. **Transparent, flat pricing, no sales cycle.** You sign up and pay a plan-based rate with included sites and per-site add-ons. There's no quote, no negotiation, and no annual minimum, which matters when you want to start this quarter rather than next. **5-layer automatic script interception.** CookieBeam's blocking engine automatically blocks classified third-party scripts loaded after the loader; inline and first-party scripts require inert markup. It intercepts scripts automatically using scan-derived script maps: createElement overrides, DOM insertion hooks, a MutationObserver fallback, Web Worker blocking, and anti-tamper protection that prevents neutralized scripts from being reverted. Blocked scripts are held in a queue and revived in order when consent is granted. Two compliance modes: Learning mode (default) allows unknown scripts while you build inventory, Strict mode blocks everything unclassified. **Connection-level blocking.** On top of script blocking, CookieBeam wraps five browser APIs (fetch, XMLHttpRequest, sendBeacon, WebSocket, EventSource) to block unconsented network requests at the connection level, category-aware. This goes beyond what most CMPs enforce. It catches tracking that happens via API calls, not script loading. Same-site requests and infrastructure hosts are auto-excluded. **3-type drift detection, continuous.** A client-side monitor runs in every visitor's browser and reports cookie drift, script drift, and connection drift to dedicated tables. Unknown items auto-promote to inventory after 5 sightings. This isn't periodic scanning; it's real-time. **GPC and DNT enforcement with per-region overrides.** Privacy signal handling is built into the blocking engine. In the EU, GPC sets default deny; explicit banner opt-in overrides it. In US opt-out states, CookieBeam follows CPRA 7025(b)(3): a privacy signal opt-out requires a deliberate, right-specific in-banner opt-in to override, not a generic Accept All. **Shield placeholders for blocked content.** When an iframe is blocked by consent rules, CookieBeam renders a visual placeholder explaining why the content isn't loading. Consent unlocks the real embed. **Server-side tagging, built in and self-serve.** CookieBeam hosts your server-side Google Tag Manager as a metered add-on, gated by consented purpose. Didomi reaches server-side through Addingwell as part of an enterprise engagement; CookieBeam bundles it into a self-serve product. See [server-side consent enforcement](https://cookiebeam.com/guides/server-side-consent-enforcement-2026). **A/B consent testing and purpose-level analytics** to measure and lift consent rates directly. See [consent-rate optimisation without dark patterns](https://cookiebeam.com/guides/consent-rate-optimization-without-dark-patterns-2026). Where Didomi is clearly ahead: enterprise preference management, OTT/CTV and publisher messaging, and the scale and account support a global media organization needs. CookieBeam doesn't compete on those. ### CookieBeam vs Didomi (as of mid-2026) | | Aspect | CookieBeam | Didomi | | --- | --- | --- | --- | | **Target buyer** | Self-serve teams and growing businesses | Enterprises, media companies, large advertisers | | | **Buying model** | Self-serve, plan-based pricing with included sites and per-site add-ons (EUR) | Sales-led, customized enterprise contracts | | | **Scope** | Web consent + 5-layer script blocking + connection-level blocking + server-side tagging | Consent + preference management, omni-channel (web/app/OTT/CTV) | | | **Standards** | GPP, Consent Mode v2, GPC/DNT enforcement with per-region overrides (not an IAB-registered TCF CMP) | TCF 2.2, GPP, Consent Mode v2, Microsoft UET, AWS; Google Gold partner | | | **Publisher / CTV messaging** | Not a focus | Yes, strengthened by the 2025 Sourcepoint acquisition | | | **Scanning** | Cookies + scripts + connections; continuous 3-type drift detection (cookie, script, connection) with auto-promote at 5 sightings | Enterprise vendor and consent monitoring | | | **Server-side tagging** | Hosted server-side GTM, self-serve metered add-on | Via Addingwell (acquired 2025), enterprise engagement | | | **Signature extra** | Connection-level blocking (unique), Shield placeholders, A/B testing, purpose-level analytics, Learning/Strict compliance modes | Preference centers, omni-channel journeys, enterprise scale | | ## Pick Didomi If... Didomi is the right platform when the requirements are genuinely enterprise: - **You need preference management, beyond a banner.** Preference centers and cross-channel privacy journeys are core Didomi territory. - **You're a publisher or media company.** OTT/CTV consent and publisher messaging, deepened by the Sourcepoint acquisition, are built for you. - **You run consent across web, apps, and connected devices** and need one platform to span them. - **Procurement expects an enterprise vendor** with a Gold Google partnership, GPP, and dedicated account support. The trade-offs: sales-led, opaque pricing, a contract cycle, and more platform than a straightforward web-consent job needs. ## Pick CookieBeam If... CookieBeam fits teams that want enterprise-grade consent mechanics without the enterprise buying motion: - **You want to start now,** self-serve, with transparent flat pricing and no negotiation. - **Your scope is web consent and measurement,** not OTT/CTV or a full preference platform. - **You need real blocking, not just tag management.** 5-layer script interception plus connection-level blocking (fetch, XHR, beacon, WebSocket, EventSource) catches tracking that other CMPs miss. - **Server-side tagging matters** and you'd rather have it bundled and self-serve than as part of an enterprise engagement. See [server-side GTM explained](https://cookiebeam.com/guides/server-side-gtm-explained-2026). - **You want continuous drift detection and GPC enforcement** with per-region legal overrides and Shield placeholders out of the box. Where CookieBeam isn't the pick: enterprise preference management, connected-TV consent, or a global media portfolio that needs Didomi's omni-channel scope and account team. ## The Fast Answer (Quick Pick) **Enterprise preference management, OTT/CTV, publisher messaging, omni-channel scope?** Didomi (now with Sourcepoint and Addingwell), and budget for a sales-led contract. **Web consent with 5-layer script blocking, connection-level enforcement, drift detection, GPC/DNT support, and server-side tagging, self-serve?** CookieBeam. For the other enterprise heavyweight, compare [CookieBeam vs OneTrust](https://cookiebeam.com/guides/cookiebeam-vs-onetrust-comparison-2026) too. ## The Bottom Line Didomi is a full enterprise privacy platform, and its 2025 acquisitions of Sourcepoint and Addingwell pushed it further into publisher, CTV, and server-side territory. If you need preference management and omni-channel consent across a large portfolio, it's built for exactly that, and priced accordingly through sales. CookieBeam covers web consent self-serve with transparent flat pricing, 5-layer script interception, connection-level blocking (unique in the market), continuous 3-type drift detection, GPC/DNT enforcement with per-region overrides, Shield placeholders, server-side tagging, and A/B testing. Match the tool to the scope: an omni-channel enterprise program points to Didomi, a focused web-consent-and-blocking setup points to CookieBeam. **Primary sources:** [Didomi CMP](https://www.didomi.io/consent-management-platform) and the acquisition announcement, [Didomi and Sourcepoint join forces](https://www.didomi.io/blog/didomi-sourcepoint) (July 8, 2025), corroborated by [Marlin Equity Partners](https://www.marlinequity.com/news/marlin-portfolio-company-didomi-acquires-sourcepoint/).
