Many discussions about DRM complexity focus on the player side: device fragmentation, codec support, CDM quirks across platforms. That's fair. The player is where things visibly break.

But every pain point on the player side has a counterpart on the license server side. Security level enforcement, multi-key encryption strategy, token lifecycle, session management - these aren't just player concerns. They're architectural decisions that span the entire chain from entitlement service to license server to CDM. And when the server side isn't designed with the same rigor as the player side, the edge cases multiply.

This article walks through the DRM challenges that teams consistently underestimate, from the perspective of what the license service needs to get right so the player can get it right.

Google Widevine recently announced that its Cloud License Service (CLS) will cease operations on April 13, 2027. While this date may seem distant, the implications for content providers and OTT platforms currently relying on this service are immediate and require careful planning.

What Does the Sunset Mean for You?

Already on Axinom DRM? Case closed. You're done. 🚀

If not, Widevine CLS' retirement means that you'll need to migrate to an alternative license service provider to ensure uninterrupted content protection and delivery. This transition period is an opportunity to evaluate your current DRM strategy and seek solutions that offer greater flexibility, higher availability, and specialized features that your current solution might lack.

In today’s digital content landscape, Google Widevine remains the most widely used DRM technology. As streaming ecosystems evolve, the demand for low-latency and highly available DRM services is growing — especially among clients operating in time-sensitive environments.

Axinom DRM is a robust multi-DRM service. For Widevine, Axinom has integrated the official Widevine License Server SDK directly into its service — enabling us to issue licenses without any dependency on Google’s own cloud service.

Did you know that Axinom DRM supports Concurrent Stream Limiting (CSL)? This feature allows you to control how many simultaneous streams a single user can initiate—enforced through robust DRM integration. As a service provider you can configure:

• The maximum number of concurrent streams
• License renewal interval and grace period
• Concurrency enforcement mode

Try out our new tool: DRM Policy Tester.

Using this tool, you can select various entitlement options with UI, see the resulting entitlement message data structure, and play a test vector directly using Axinom Media Tools.

Video and streaming businesses turn to Digital Rights Management (DRM) to secure their content, but simply adding DRM is not enough. The effectiveness of DRM depends on how it is implemented and how well it is integrated into a broader security strategy. Poor implementation can lead to vulnerabilities that pirates exploit, negating DRM’s intended purpose.

Since Google revoked CDMs for older browsers on October 31, 2024, we observe an elevated level of Widevine DRM license rejected errors. We recommend our customers to observe the client error messages, and if "revoked" errors are encountered, to update users' browsers. With the latest revocation, it requires a Chrome version 117+ to deliver a Widevine license successfully.
