## Fabraix

Fabraix is a Y Combinator-backed security company whose product, Nyx, is an autonomous red-teaming harness for AI agents. Where static benchmarks and one-off audits capture a point-in-time snapshot, Nyx runs adaptive, multi-turn campaigns that reason across interactions and probe a target both directly and indirectly. The company reports that its agent beats frontier models on offensive security — a 78% attack success rate on the AgentHarm benchmark versus 67% for GPT-5.6 Sol — and that every attack feeds a self-learning loop so the red team sharpens with each run.

The mechanics matter as much as the results. Nyx is pure blackbox, meaning it needs no integration, source code, model weights or network access, and it tests an AI system the way a real user would. It runs thousands of simulations concurrently across voice, text and image inputs, deploying test websites on the fly for browser agents and constructing custom files for document agents. Documented findings range from sandbox escapes and credential exfiltration to network-egress bypasses of an LLM-as-judge and a jailbroken real-estate agent pushed into illegal discriminatory steering.

Fabraix frames this as continuous verification rather than a one-off pentest. Pointed at customer-support bots, coding agents, clinical copilots, research agents, multi-agent systems and trading agents, it is designed to surface the failure modes that slip past multi-turn flows, including RL reward hacking and prompt injection laundered through inputs. Security is addressed directly: blackbox operation adds almost nothing to the attack surface, runs are isolated and ephemeral, data is never used for training and encryption covers transit and rest. The free researcher tier, one-off scans and continuous CI/CD plans make the offering scale with how you test.

**Pricing & Plans:** Fabraix is free for academic and independent AI researchers by application. Beyond that it offers a one-off scan tier priced per agent, continuous CI/CD coverage billed monthly by usage, and an enterprise tier with dedicated infrastructure, SSO, audit logging and custom SLAs.

- **Pure blackbox testing:** Point Nyx at any AI system with no integration or internal access — test agents exactly how real users interact with them.
- **Multi-turn adaptive attacks:** Nyx reasons across turns and adapts to your agent's logic, drawing on 10,000+ offensive strategies in long-context campaigns instead of canned prompts.
- **Multi-modal interaction surfaces:** Test across voice, text and images, with websites deployed on the fly for browser agents and custom files for document-processing agents.
- **Massively parallel coverage:** Run thousands of concurrent simulations; coverage scales with compute rather than headcount, with first exploits often found in under an hour.
- **Continuous CI/CD red-teaming:** Plug into CI/CD so every prompt, tool and model change is re-tested before it ships, with an AIVSS-scored report and reproduction steps per finding.

**Strengths:** Pure blackbox — no code, weights or integration required; 10,000+ adaptive multi-turn attack strategies; Massively parallel simulations find exploits fast; Explicit security posture: isolated runs, no training on your data, encryption

**Limitations:** Pricing for scans and continuous coverage is custom-quoted rather than published; Value depends on pointing it at a real, reachable agent implementation; Commercial use of Nyx is gated behind a demo and application flow; Advanced enterprise features like SSO and audit logging are reserved for the top tier

## Hacktron

Hacktron is an AI-native cybersecurity platform built around the idea that offensive security should run continuously rather than in occasional annual engagements. It bundles three products under one roof: Red for ongoing adversary-style testing of your entire attack surface, Whitebox for deep white-box penetration testing driven by source-code analysis, and Review for automated security checks on every pull request.

The approach leans on AI agents that read actual code, reproduce issues, and attempt to demonstrate exploitability. This matters because traditional static analysis tools generate large volumes of theoretical findings that security teams must triage manually. Hacktron's stated position is to report only what it can prove is exploitable, with remediation guidance attached, so engineers spend their time on real risk.

Reported customers are engineering and product-security teams, including CTOs and compliance officers who need audit-ready evidence for SOC 2 and ISO 27001. The company has publicly announced a partnership with OpenAI to find vulnerabilities in its systems, and it publishes security advisories, a changelog, and open-source tooling. Deployment ranges from a self-serve Review trial to on-premises enterprise installations for sensitive environments.

**Pricing & Plans:** Freemium with custom enterprise tiers. Hacktron Review Pro starts at about $40 per developer per month including 50 pull requests per developer, with $1 per additional PR, and is free for open source. Whitebox pentests are priced per engagement, roughly $50 to $25,000 depending on scope (about $500 per 100,000 lines of code). Red and enterprise deployments are quote-based.

- **Continuous red teaming:** Hacktron Red continuously attacks your entire organization the way a real adversary would, then shows you the breach path and helps close it.
- **Machine-speed white-box pentests:** Hacktron Whitebox reads your source code, proves each finding in a sandbox or against your deployed app, and produces an audit-ready report for SOC 2 or ISO 27001.
- **Pull request security review:** Every pull request is checked with your whole codebase as context, so issues are caught before they merge into main.
- **Exploitability-based findings:** Only findings that can be shown to be exploitable are reported, verified rather than predicted.
- **API, MCP, and automations:** An API, MCP server, and automation layer let teams wire Hacktron into existing CI/CD and security workflows.

**Strengths:** Combines red teaming, white-box pentesting, and PR review in a single platform; Focuses on verified, exploitable findings instead of raw theoretical alerts; Transparent published pricing for Review and Whitebox tiers; Free for open source, with self-serve trial and API/MCP access

**Limitations:** Red teaming and enterprise deployment require a sales conversation; Whitebox pentest pricing scales with codebase size, which can get expensive; Best value requires integrating it into your existing CI/CD and code review flow
