From dailies on set to the final master, we assess the physical, digital, and workflow controls guarding premium content — aligned to TPN and MPA Content Security Best Practices, built for studios, streamers, and every vendor in the supply chain between them.

TPN-Aligned Assessment Methodology
Content Security Physical + Digital + Workflow
Independent Vendor-Neutral Review

If content passes through you,
this is for you.

Studios now require content security assessments from everyone touching pre-release material — not just the biggest vendors. If any of this is you, an assessment is likely already on your client's checklist.

🏢

Studios & Networks

Vetting your own facilities and vendor ecosystem against TPN and internal content security standards.

📺

Streaming & OTT Platforms

Securing original content pipelines from acquisition through encode, packaging, and delivery.

🎬

Post-Production & VFX Houses

Edit bays, render farms, and review rooms handling unreleased footage and assets.

🗣

Dubbing & Localization Vendors

Script, audio, and video access across distributed, often global, freelance workflows.

💿

Distribution & Mastering Vendors

DCP creation, mastering, QC, and delivery pipelines handling final and near-final assets.

📡

Broadcast & Live Events

Feed security, credential control, and facility access for live and time-sensitive content.

📢

Marketing & Ad Agencies

Trailers, screeners, and campaign assets shared ahead of public release.

Cloud & MAM/PAM Providers

Media asset management and cloud workflow platforms storing client content at scale.

You might already think you're covered.

"We already passed our TPN assessment."
TPN assessments are a point-in-time snapshot, and controls drift between annual reassessments. A readiness review closes the gap before your assessor finds it — not after.
"Our IT team handles security."
Most internal IT teams aren't fluent in the specific criteria TPN and MPA Content Security Best Practices require — screening room controls, watermarking, chain of custody, and physical-plus-digital convergence. That's a specialized review.
"We're a small post house — this is for big studios."
Studios now push TPN requirements down the entire vendor chain. Vendors of every size handling member content are being asked to complete an assessment before onboarding — and blocked from new work without one.
"We already have physical security."
Content security isn't just cameras and badges. It's physical access converged with digital controls, watermarking, and workflow discipline — the exact intersection TPN and MPA CSBP were built to evaluate.

Built by practitioners,
not theorists.

AppSec Sentinel was founded by a SANS GIAC-certified security engineer with hands-on experience architecting secure workflows for media production environments — working at the intersection of physical security, cloud infrastructure, and content protection where most firms only cover one.

Our practice is grounded in real-world security operations across the content supply chain — hardening cloud editing and rendering environments, enforcing network segmentation and endpoint controls across hybrid production infrastructure, and conducting content security assessments aligned to MPA Content Security Best Practices and TPN criteria. That operational depth is what separates our findings reports from checkbox audits.

Content Security Risk Assessment

A full-spectrum review across physical, digital, and workflow controls protecting pre-release and in-production content. We examine your facility, your systems, and your people — and translate findings into a prioritized, studio-ready risk register.

  • Facility and physical security review (access control, CCTV coverage, visitor logs, screening rooms)
  • Digital workflow and cloud security review (storage, transfer, editing and rendering environments)
  • Personnel and insider-risk controls (background checks, NDAs, least-privilege access)
  • Content tracking, watermarking, and chain-of-custody evaluation
  • Risk register mapped to MPA Content Security Best Practices categories
  • Executive summary built for studio and vendor relationship stakeholders

TPN Readiness Assessment

A pre-assessment engagement that mirrors the official TPN AAA methodology, so there are no surprises during your real assessment. We find and close the gaps before your assessor does.

  • Gap analysis against current TPN assessment criteria
  • Mock assessment interviews and facility walkthrough
  • Evidence and documentation review (policies, logs, diagrams)
  • Prioritized remediation plan before your scheduled TPN assessment
  • Support coordinating with your assigned TPN assessor
  • Annual reassessment readiness check-ins

Vendor & Third-Party Security Assessment

For studios and platforms vetting the post-production, VFX, dubbing, and distribution vendors that touch their content — before access is granted, not after.

  • Vendor security questionnaire design and review
  • On-site or remote facility assessments of key vendors
  • Risk scoring across your full vendor portfolio
  • Ongoing monitoring recommendations for high-risk partners

Digital Workflow & Cloud Security Review

Engage before you migrate to a new MAM/PAM, cloud editing suite, or remote collaboration platform, and surface security issues while they're still cheap to fix.

  • Cloud infrastructure and SaaS platform review (MAM/PAM, remote workstations)
  • DRM and forensic watermarking configuration guidance
  • Secure file transfer protocol review (Aspera, Signiant, MASV)
  • Secure-by-default configuration recommendations before rollout

Adversarial Content-Security Thinking

Media content security requires thinking like both a physical intruder and a digital adversary — tracing how a screener leaks, how a workstation gets isolated from the internet, how a dailies folder ends up on an unmanaged device.

Most reviews validate the policy. Ours pressure-test the workflow.

Risk That Studios and Executives Understand

Findings fail when they stay technical. We translate them into business impact — contractual risk, loss of studio relationships, leaked pre-release content, brand damage — so leadership can prioritize with confidence.

Our reports are built for studio relationships, not just security teams.

Operational Media Security Experience

Certified across security engineering disciplines, with direct hands-on experience securing production, post, and cloud content workflows at scale. We know what good looks like because we've built it.

Experience earned on real productions, not just in a classroom.
