## 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

## QA.tech

QA.tech positions itself as the verification layer for teams shipping software with heavy AI assistance: coding got much faster, but review and QA did not keep pace. Instead of maintaining a fragile library of selectors and scripts, QA.tech runs autonomous agents that open your live web or native mobile app, work toward goals the way a person would, and report back on what actually works before code is merged.,The product is built around continuous, dynamic testing rather than one-off suites. Connect GitHub, GitLab or Bitbucket and a CI provider, and agents automatically pick up each pull request together with its preview environment, run end-to-end and exploratory passes, and comment on the PR with results. When something fails, you get screenshots, console and network activity and the agent's reasoning at the point of failure, which shortens time to root cause considerably.,Testing is also context-aware over time. Journeys and domain rules you spell out in chat accumulate as knowledge the agents reuse on every later run, and a blast-radius view flags changes that ship untested because a required test user or journey is missing. The platform is cloud-native, needs no code access, and is targeted at QA leads, engineers, CTOs and DevOps teams; Vercel Ventures and founder investors back the company. Pricing is not published as a simple self-serve number — teams book a demo, though a free getting-started path is offered.

**Pricing & Plans:** Enterprise-style, contact-for-pricing model: the site offers a free getting-started path and a demo booking rather than public per-seat numbers, so exact costs depend on team size, coverage scope and mobile testing needs.

- **Plain-language test authoring:** Describe a journey or rule in chat and the agent turns it into durable test cases that survive refactors and redesigns.
- **PR-level verification:** Every pull request gets a dynamic exploratory pass with preview environments, failure breakdowns, screenshots, console and network logs.
- **Web and native mobile:** Agents target real browsers and native iOS and Android apps, so coverage reaches beyond the web front end.
- **CI, Git and issue-tracker integrations:** Findings flow into Jira and Linear, and agents can be queried over MCP by other coding agents.
- **Blast-radius analysis:** Detects when changes to a module are untested and recommends the exact journeys or test users needed to close the gap.

**Strengths:** Agents test visually without selectors, so suites survive redesigns and framework migrations; Runs automatically on every pull request with preview environments; Plain-English test authoring is accessible to non-engineers; Rich failure evidence — screenshots, logs, network data and agent reasoning
