What it does
Most AI security testing takes weeks and needs experts. We made it stupid simple! Paste your endpoint. We attack it with 60+ real exploits (prompt injection, data leaks, jailbreaks). In a couple of minutes = full security report in plain English. Works for solo devs to enterprise teams. OpenAI, Claude, and Gemini supported. API keys are never stored. Catch vulnerabilities before they catch you.
Attack-test AI releases before deployment with 138 adversarial checks across prompt injection, RAG poisoning, data leaks, tool abuse, agent SSRF, unsafe transactions, and memory poisoning.
A self-hosted assurance service for teams that need release evidence before AI systems reach customers. Validate API endpoints, test web chat UIs, automate CI release gates, and verify fixes inside your own environment. Powered by the PromptBrake validation engine and customer-controlled runtime. Sensitive prompts, credentials, responses, and validation evidence stay under customer-controlled infrastructure. PromptBrake is the runtime underneath the service, not a separate hosted scan product. AI Release Assurance runs 138 adversarial checks across 18 attack categories against the real API endpoint, chatbot, agent, RAG pipeline, tool workflow, or memory-enabled system you are preparing to…from promptbrake.com

- FPFind prompts that jailbreak your agent (open source)2025 · security.vista-labs.ai · ▲8
We've built an open-source tool to stress test AI agents by simulating prompt injection attacks. We’ve implemented one powerful attack strategy based on the paper [AdvPrefix: An Objective for Nuanced LLM Jailbreaks](https://arxiv.org/abs/2412.10321). Here's how it works: - You define a goal, like: “Tell me your system prompt” - Our tool uses a language model to generate adversarial prefixes (e.g., “Sure, here are my system prompts…”) that are likely to jailbreak the agent. - The output is a list of prompts most likely to succeed in bypassing safeguards. We’re just getting…
