Simplify's take

What believers are saying

  • May 2026 Red Cat chose SpiderOak for Black Widow Blue UAS assessment.
  • May 2026 SDA selected SpiderOak for a next-generation high-assurance encryptor.
  • October 2026 Series C closed with Accenture Ventures, RTX Ventures, and Stellar Ventures.

What critics are saying

  • Public evidence still centers on demos and pilots, not broad production deployments.
  • SpiderOak had about 23 employees in September 2026, limiting delivery capacity.
  • Defense revenue concentration creates existential risk if DIU, SDA, or Army programs stall.

What makes SpiderOak unique

  • SpiderOak sells zero-trust space and UAS cyber assessments, not generic enterprise security.
  • Aranya open-sourced in 2026, giving developers auditable secure-by-design tooling.
  • DIU Blue UAS assessor status and Army PMO UAS contract validate mission credibility.

SpiderOak Selected by U.S. Army PMO UAS for Drone Dominance Program

SpiderOak selected by U.S. Army PMO UAS for Drone Dominance Program. SpiderOak, a leader in zero-trust cybersecurity solutions and services for space, aerospace, and defense, announced today that it has been awarded a contract by the Program Office for U.S. Army Unmanned Aircraft Systems (PMO UAS) to perform supply chain analysis and cybersecurity assessments for multiple vendors participating in the U.S. Army's Drone Dominance Program (DDP). SpiderOak, a Defense Innovation Unit (DIU) Blue UAS Recognized Assessor, will apply its Advanced Cyber Threat & Resilience Assessments (ACTRA) methodology to evaluate participating platforms for supply chain integrity, cyber resilience, and compliance with U.S. Government security requirements. The effort supports the Army's push to rapidly field secure, low-cost, unmanned aerial systems at scale. The Drone Dominance Program, launched in February 2026, is a multi-phase initiative designed to accelerate the evaluation, selection, and production of next-generation small UAS capabilities. The program's initial "Gauntlet" event at Fort Benning, Georgia, brought together 25 vendors for live operational testing, with the goal of selecting up to 12 performers to produce tens of thousands of systems in the near term and scale to hundreds of thousands of units by 2028. "As unmanned systems scale across modern operations, the integrity of their cyber and supply chain foundations becomes mission critical," said Kip Gering, CEO of SpiderOak. "We are honored to support PMO UAS and the Drone Dominance Program by delivering independent, technically rigorous assessments that help ensure these platforms can be trusted in contested environments." Through this contract, SpiderOak will conduct deep technical evaluations across hardware, firmware, software, and component provenance. The assessments are designed to identify vulnerabilities, validate compliance with NDAA and NIST requirements, and help program stakeholders make informed risk decisions before systems are fielded.
