Chi sono
I'm Alexander Hearn, a Cybersecurity Specialist at Handshake, where I red-team LLM systems. I earned a B.S. in Computer Science (Cybersecurity specialization) from the University of Maryland and hold a GISF certification.
I help teams find and fix security weaknesses in their AI products:
- System prompt hardening and prompt-injection testing
- RAG evaluation test sets
- Vendor security questionnaire completion
- Expert-reviewed AI agent and MCP security assessments
You get clear, prioritized findings so you know what to fix first and why. All work is AI-assisted, expert-reviewed delivery.
