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 flat per-domain pricing, and it includes server-side tagging, connection scanning, 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 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 and measurement well, self-serve.
Transparent, flat pricing, no sales cycle. You sign up and pay a flat per-domain rate. There's no quote, no negotiation, and no annual minimum, which matters when you want to start this quarter rather than next.
Connection scanning with drift detection. CookieBeam records outbound network connections and loaded scripts, beyond the cookies a page sets, and flags drift when something new shows up, catching cookieless tracking and later tag additions.
Server-side tagging that's 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.
A/B consent testing and purpose-level analytics to measure and lift consent rates directly. See consent-rate optimisation without dark patterns.
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.

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.
- 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.
- You want connection scanning and A/B testing to catch drift and improve consent rates.
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
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 done well, self-serve, with server-side tagging, connection scanning, and A/B testing? CookieBeam.
For the other enterprise heavyweight, compare CookieBeam vs OneTrust 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 the core web-consent job self-serve, with transparent flat pricing and server-side tagging, connection scanning, and A/B testing included. Match the tool to the scope: an omni-channel enterprise program points to Didomi, a focused web-consent-and-measurement setup points to CookieBeam.
