What is IOActive, Inc.?

Founded in 1998 by Joshua Pennell and led since 2008 by Jennifer Sunshine Steffens, IOActive is headquartered in Seattle with offices in Atlanta, London, Madrid, and Dubai. The firm is known for full-stack security assessments and deep specialism in hardware, embedded systems, semiconductors, automotive, industrial control, and other safety-critical environments.

Best for: OEMs, semiconductor vendors, automotive, and critical-infrastructure operators that need silicon-to-cloud security expertise
Pros

  • ✓ Independently owned since 1998 with stable senior consultant tenure

  • ✓ Specialist labs for hardware bring-up, fault injection, and chip-level analysis
Considerations
