Securing The Stream: How End-to-End Video Platforms Are Combating Piracy
Illegal streaming is reaching unprecedented levels worldwide, posing a serious threat to sports streaming revenue. In the U.S., 35% of NFL fans admit to watching games through illegal means. In England, Scotland and Wales, over 8 million adults have either admitted to or were likely to watch pirated sports streams. And in France, more than half of viewers of the 2024 Ligue 1 Classico OM-PSG match accessed the game via illegal streams. These are not isolated cases—piracy is a rampant issue that is affecting sports streaming service providers worldwide.
The financial stakes of illegal streaming are enormous, as illegitimate viewership jeopardizes revenue from subscriptions and advertising, threatening the sports ecosystem. With over $60 billion invested annually in global sports media rights, broadcasters and content owners cannot afford to lose audiences to unauthorized platforms. Video service providers must prioritize anti-piracy initiatives to safeguard premium sports streaming content and protect their revenue.
Inside the Pirate Playbook: Key Methods of Illegal Sports Streaming
Two tactics stand out among the myriad piracy methods currently threatening sports streaming services. These are restreaming and CDN leeching.
Restreaming is a traditional piracy method where a pirate subscribes to a legitimate streaming service and accesses the content legally. The pirate hacks the HDMI interface and HDCP protocol, extracts the video signal and reencodes it for illegal distribution via a social network platform or through a private distribution network. Restreaming poses a serious threat to content owners as it evades digital protections and creates unauthorized duplicates of premium sports streams.
Restreaming bypasses digital protections by extracting and illegally redistributing streams from legitimate streaming services.
CDN leeching is a more recent, and increasingly dangerous, piracy method. Instead of reencoding the stream, pirates hack into the original subscriber's app to steal the live content URL and DRM keys. These are then shared broadly with users who directly access the legitimate content from the original CDN. The streaming service not only loses on revenue but also bears the cost of delivering the stolen streams. In addition, CDN leeching can also degrade service quality for paying subscribers due to unexpected traffic spikes. This form of piracy is difficult to detect and mitigate because it involves real CDN traffic from unauthorized users. Studies estimate that 40-50 percent of high-demand content in Europe, including live sports broadcasts, is illegally redistributed through CDN leeching.
CDN leeching is a stealthy piracy method where pirates hijack live stream URLs and DRM keys, causing revenue loss and service degradation by redirecting real CDN traffic to unauthorized users.
CDN leeching often exploits several overlooked weaknesses in video streaming infrastructure. A lack of analytics and monitoring can prevent service providers from detecting content theft and consequently delay countermeasures. Weak app protection and insufficient anti-tampering measures make it easier for attackers to reverse-engineer applications. Additionally, vulnerabilities in DRM implementation — such as outdated or unrefreshed key encryption — can expose content to unauthorized access. Many systems also lack robust CDN client authentication, leaving them vulnerable to piracy. Finally, inadequate filtering of user requests, such as insufficient geo-blocking or VPN detection, can allow pirated streams to be accessed from outside designated markets. Addressing these gaps is essential for safeguarding premium content and maintaining service integrity.
Four Strategies to Combat Piracy in Live Sports Streaming
As live sports streaming grows in popularity, piracy methods are becoming more sophisticated. To protect valuable content and sustain business models, video service providers are deploying end-to-end video streaming solutions that support a range of tools designed to prevent illegal content distribution:
Fighting sports streaming piracy requires multiple layers of security, including geo-blocking, CDN authentication, robust DRM and watermarking.
Advanced Geoblocking Controls
Geoblocking is a technique used by content providers, broadcasters and streaming platforms to restrict access to video content based on a user's geographic location. This technique not only ensures legal compliance but also acts as a critical deterrent against the widespread distribution of pirated content.
Geoblocking works by identifying a user’s IP address and determines the country or region they’re accessing from — then allowing or denying access to specific content. Geoblocking is essential for complying with sports media rights, which vary by region and event.
However, complex licensing scenarios—such as a broadcaster having rights to one league in multiple countries and another league in only one country—can make it challenging to enforce geoblocking. Without precise geoblocking mechanisms, service providers may be forced to compromise compliance or lose subscribers.
Moreover, in the absence of effective geoblocking, users in restricted regions may also turn to unauthorized sources to access content, leading to a significant increase in digital piracy. To address this issue, service providers are embracing URL-based geoblocking on their video streaming platform integrated with content management systems and CDNs. This approach allows them to apply granular rules on a per-event or per-league basis, dramatically reducing unauthorized access from outside designated territories.
CDN Client Authentication and Tokenization
Ensuring that only legitimate users can access video streams is critical for live sports streaming. This can be achieved through client authentication tokens, which are validated by the CDN before delivering content. Unauthorized requests lacking valid tokens are rejected, even if they originate from within the licensed region. Token-based access control, along with support for multi-CDN environments, ensures greater protection across a distributed delivery infrastructure.
The industry is working toward standardizing token-based authentication across CDNs through the Common Access Token initiative. This effort aims to simplify stream protection and piracy mitigation for content providers using multiple CDNs. It does this by enabling a unified token mechanism for easier identification and access control.
Robust DRM Key Management
Strong encryption protocols are also key to deterring illegal sports streaming. A best practice is to assign unique encryption keys for each live event, making it difficult for pirates to reuse keys across events.
Advanced approaches like per-profile keying provide an additional layer of security by encrypting each encoded profile and audio with separate keys. This strategy allows content to be distributed according to the decryption capabilities of different devices, thereby minimizing risk. For example, cracking the key for a low-resolution stream doesn’t compromise high-definition or premium-tier content. Regular key rotation also enhances protection for linear channels.
Ultimately, these encryption measures ensure that service providers can deliver high-quality sports content securely, protecting against unauthorized access and distribution.
Forensic Watermarking
Restreaming remains one of the most widespread piracy threats. To combat this, service providers are increasingly adopting forensic watermarking. With this approach, each stream is invisibly marked with a unique identifier linked to the subscriber or device. If a pirated feed surfaces online, forensic tools can trace it back to the original source.
Some watermarking solutions use AB watermarking, which involves alternating segment sequences to create a unique signature per session. The specific sequence of A and B segments enables forensic analysis to identify the source of illegal streams and take real-time action. If a particular video session is identified as the source of illegal streams on the internet, service providers are notified and can decide to stop the corresponding stream delivery in real time. Many operators deploy watermarking as an event-based service on their video streaming platform. Watermarking as a service protects high-value sports content while optimizing cost efficiency.
Protecting Premium Sports Content with an End-to-End Video Streaming Solution
Piracy is a serious threat to sports streaming, undermining the value of premium content and disrupting revenue models. To mitigate this risk, video service providers must strike the right balance between comprehensive content protection and operational cost efficiency.
The most effective path forward lies in adopting an end-to-end video streaming platform that integrates robust security features—such as watermarking, DRM, token-based authentication and geoblocking—in a single solution. This holistic approach not only simplifies implementation but also strengthens the overall defense against piracy while enabling high-quality sports streaming.

It's probably the fifth or sixth time that I've done so in the last decade, but an interesting dichotomy popped up during the prep meeting with panelists, and again while we were on stage during the live session. The concept was "casual piracy" and how it differed from "professional piracy" in both intent and scale.
