MPA Announce Updated Content Security Best Practices v5.3.1 and the new four-tier Trusted Partner Network Shield System launching on September 9

The Trusted Partner Network (TPN) has just released a significant update to its Motion Picture Association (MPA) Content Security Best Practices, version 5.3.1, alongside a major enhancement to the TPN Shield System. As a long-standing supporter of robust content protection standards, ConvergentDS welcomes these changes and the clarity they bring to the media and entertainment ecosystem.

What's New in TPN v5.3.1?

The new version of the MPA Content Security Best Practices focuses on refining application security through several key additions:

• A targeted Scoping Baseline Questionnaire to guide assessment efforts.
• Four new security controls specifically designed to strengthen application security.
• A detailed change log to make it easier for stakeholders to identify what's been added or revised.

These changes aim to improve consistency across TPN assessments and better reflect evolving threat landscapes.

The Next-Gen TPN Shield System

In tandem with the updated Best Practices, TPN has announced a new four-tier Shield System, set to launch on September 9, 2025. This updated framework provides:

• Greater visibility into remediation progress
• A more transparent and structured approach to security maturity
• An easier way for content owners to evaluate vendor readiness and compliance

The four-tier Shield model is expected to drive higher accountability while supporting organizations in tracking their continuous improvement journey.

Why It Matters

At ConvergentDS, we know how complex it can be to navigate evolving security standards. TPN's updates represent a significant move toward clarity and consistency, both for vendors preparing for assessments and for content owners assessing risk across their supply chain.

By aligning with these changes early, service providers can demonstrate proactive security posture and stand out in a competitive vendor landscape. For studios and rights holders, the enhanced Shield System enables quicker, more informed decisions around vendor risk and remediation needs.

Join the Conversation

TPN will host informational webinars on August 20 and 21 to explain the changes in more detail and answer stakeholder questions. We encourage all our partners to attend and stay ahead of the curve.
