Descriptiontext

PurpleSec is a Washington DC-area AI cybersecurity company founded in 2019, operating with a headcount of 1–10 employees and no disclosed external funding. Its core product, PromptShield™, is an intent-based Prompt Web Application Firewall that analyzes the intent and context of AI interactions to detect and deflect prompt injections, data exfiltration, model misuse, shadow prompting, and prompt obfuscation. The platform's Adaptive Defense capability self-trains from every attempted attack, while a Consistency Layer provides disguise detection across multiple LLMs and AI tools. The architecture is rooted in ISO/IEC 42001 AI management system governance and is positioned as a holistic solution spanning endpoints to cloud surfaces.

The company monetizes through subscription-based enterprise sales, supported by a hybrid go-to-market that combines free assessment tools and an AI Security Framework for product-led entry with 'Request A Consultation' and 'Get A Demo' consultation CTAs for enterprise conversion. Revenue is complemented by adjacent services including AI Readiness Assessments, AI/LLM Security Testing, and a Virtual CISO offering. Customer segmentation spans enterprise organizations broadly, with dedicated positioning for healthcare, finance, AI builders, AI systems integrators, AI DevOps, and datacenter/network operations, plus a channel partner program for resellers and MSPs.

Marketing is content-driven, anchored by a blog, podcast, newsletter, and 'The Breach Report' thought-leadership series. Leadership comprises Jason Firch as Co-Founder, CEO, and Head of Marketing, and Joshua Selvidge as CTO, with a team described as DoD-trained and mission-driven. The company is privately held with no institutional investors, parent company, acquisitions, patents, or disclosed awards evidenced in the available data, and revenue is not publicly disclosed.
