Strategy

Cyber T&E Strategy

Help programs define test objectives, interpret findings, and communicate mission risk.

Programs

Technical Program & R&D Support

Advise on requirements, technical roadmaps, prototypes, and the transition from research to operational use.

Assurance

Secure Software Assurance

Advise on the use of static analysis, dependency analysis, performance testing, test coverage, and directed fuzzing to evaluate software.

Fuzzing AS a Service

Fuzzing expertise for mission-critical software.

VCS provides Department of Defense programs with specialized subject matter expertise in fuzzing and dynamic software analysis. Our team brings hands-on experience across multiple fuzzers and strategies—from fuzzer development and target preparation through failure analysis and patch validation.

  • DoD program support
  • Fuzzer development & evaluation
  • Multiple fuzzers & strategies
  • Failure analysis through patch validation

  1. Engineer the targetDevelop harnesses and representative input corpora in collaboration with the software team.
  2. Execute the campaignSelect and configure appropriate fuzzers and strategies to explore meaningful program paths.
  3. Triage the findingsDeduplicate failures and provide reproducing inputs, crash reports, and source-level analysis when available.
  4. Validate the correctionExercise patched software and preserve useful inputs for future regression testing.

Engagement Outcomes

What VCS delivers

  • A minimal, deduplicated set of discovered failures
  • Reproducing inputs and actionable crash reports
  • Root-cause analysis when source code is available
  • Patch verification and regression-test inputs
  • Guidance for incorporating fuzzing into the development lifecycle

Fuzzing complements unit testing, integration testing, and static analysis by exercising behavior those tests may miss.
