Step 2 Rising risk of prompt injection attacks targeting agents

→

Step 3 Educational Platform to build dev team prompt injection defense capabilities

Problem

As agent architectures that execute external tools become ubiquitous, prompt injection attacks that trick agents into running malicious commands have emerged as a critical new threat. However, most dev teams (especially those with 10 or fewer members) have no systematic way to learn about prompt injection attack vectors, discovering vulnerabilities only after deploying agents. The average incident response cost per security breach ranges from $37,500–$150,000.

Solution

A CTF (Capture The Flag)-style educational Platform offering hands-on prompt injection attack and defense exercises. Provides attack scenarios tailored to agent architectures (ReAct, Plan-Execute, Multi-Agent), difficulty-tiered challenges, a defense pattern library, and team-level security competency scoring.

Target: Development teams and CTOs at Startups with 5–30 employees that build and deploy AI agents

Revenue Model: Team Subscription at $59/month per team (up to 5 members), plus $11/month per additional member. Custom enterprise challenge creation at $750 per engagement.

Ecosystem Role: Education
