Feature	Fabraix
STOA Rating	4.0
Description	Fabraix helps you understand how hard it is to break your AI agents (automated software that acts on your behalf) by measuring the cost an attacker would need to exploit them. You get a clear security score so you can fix weak spots before they become real problems. It's built for teams that are deploying AI-powered tools and need to know their risk level.
Strengths	•Focuses on a specific, underserved problem: AI agent security testing •Introduces a concrete metric (ACE score) that gives you a measurable way to track risk •Research-driven approach adds credibility for technical buyers
Weaknesses	•No public pricing — hard to evaluate cost without contacting sales •Very early-stage with limited public information about features or integrations •Likely too specialized for SMBs not already running AI agents in production
Key Features	•Measure the Adversarial Cost to Exploit (ACE) score for your AI agents •Identify security weak spots in AI-powered workflows before attackers do •Get research-backed benchmarks to compare your AI agent's resilience
Pricing	Contact for pricing
Best For	All industries
AI Features	AI-Powered Fabraix analyzes AI agents for security vulnerabilities using adversarial testing methods to calculate an exploit cost score.
Categories	AI Tools & AssistantsBuild with AI
STOA Verdict	Fabraix is for tech-forward small businesses that are already running AI agents and need to prove those tools are secure. The ACE scoring concept is genuinely useful if you're in that situation. But if you're not actively deploying AI agents yet, this tool won't help you today — and with no public pricing, you can't even estimate the cost.
