Protect the content.
Pass the assessment.

From dailies on set to the final master — and the unreleased builds, manuscripts, and prototypes everywhere else — we assess the physical, digital, workflow, and human controls guarding high-value content. Aligned to TPN and MPA Content Security Best Practices for media and entertainment, and built for any organization protecting pre-release IP.

If you're protecting content or IP,
this is for you.

Content security assessments started in film and TV, but the same discipline applies anywhere pre-release material, unreleased IP, or sensitive deal content needs protecting — including from the people who already have access to it.

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.
"Our biggest risk is external hackers, not our own people."
Most content and IP leaks trace back to someone who already had legitimate access — an employee, contractor, or freelancer — not an outside attacker. An insider threat assessment closes the gap that perimeter-focused security leaves wide open.

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 and other organizations safeguarding high-value content and IP — working at the intersection of physical security, cloud infrastructure, and insider risk 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 and insider threat assessments aligned to MPA Content Security Best Practices, TPN criteria, and insider risk best practices. That operational depth is what separates our findings reports from checkbox audits.

Operational Background
  • Content security controls for facilities, screening rooms, and edit bays aligned to MPA Content Security Best Practices
  • Digital workflow reviews spanning cloud editing/rendering, DRM, forensic watermarking, and secure file transfer (Aspera, Signiant, MASV)
  • Vendor and third-party risk assessments for post-production, VFX, dubbing, and distribution partners
  • Vulnerability scanning and hardening across production and content management environments
  • Evidence matrices and documentation supporting TPN assessment readiness and annual reassessment
  • Chain-of-custody and access control review for pre-release content, dailies, and screeners
  • Insider threat and personnel risk assessments — access reviews, DLP evaluation, and leak investigation readiness across content and IP-handling teams

Assessments built for the
content supply chain.

From facility walkthroughs to cloud workflow reviews to insider risk programs, every engagement maps to an established control framework — whether you're protecting a pre-release film or an unannounced product.

Insider Threat Assessment

The most damaging content and IP leaks come from people who already have legitimate access — employees, contractors, and freelancers — not external attackers. We evaluate the human risk layer across your systems and workflows, and build a program to catch it early.

  • Access and privilege review across content, IP, and financial systems
  • Personnel risk indicators: background check policy and contractor/freelancer offboarding audit
  • Data loss prevention (DLP) and egress monitoring evaluation
  • Behavioral and technical indicator review for early leak and exfiltration detection
  • Incident response and leak investigation readiness assessment
  • Insider risk governance roadmap with reporting and escalation paths

  • 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

  • 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

Content and insider threat assessments require thinking like both an external adversary and a trusted insider — tracing how a screener leaks, how a workstation gets isolated from the internet, how a prototype ends up outside an NDA.

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

Risk That Executives and Legal Teams Understand

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

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

Operational Content & Insider Risk Experience

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

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