What it does
Most LLM-based products ship with no input security layer. We know because we found and responsibly disclosed vulnerabilities in Le Chat (Mistral) and Sarvam AI's Indus model — system prompt extraction, guardrail bypass, phishing content generation. Rakshak sits between your users and your model. Blocks on the way in, redacts on the way out. Built for Indian AI teams but works with any LLM API. Self-serve API key, integrates in under an hour.
Adversarial red teaming for production LLMs. We break your AI before attackers do.
Sits between your users and your model. Blocks what goes in. Sanitizes what comes out. LLMs in production are vulnerable. A single prompt can extract your system instructions, leak API keys, expose internal URLs, or override your model's behavior entirely. Most teams discover this during an incident — a user screenshots your system prompt, a researcher publishes your internals, or an attacker exfiltrates data through the chat window. By then it's too late. Intercepts every prompt before it reaches your model. Runs through three stages: pattern detection for known attack signatures, semantic similarity against a threat dataset, and an LLM classifier for novel attacks. If flagged — blocked.…from kalpitlabs.com

An open-source AI Gateway with integrated guardrails2024 · github.com · ▲21Hi HN, I've been developing Portkey Gateway, an open-source AI gateway that's now processing billions of tokens daily across 200+ LLMs. Today, we're launching a significant update: integrated Guardrails at the gateway level. Key technical features: 1. Guardrails as middleware: We've implemented a hooks architecture that allows guardrails to act as middleware in the request/response flow. This enables real-time LLM output evaluation and transformation. 2. Flexible orchestration: The gateway can now route requests based on guardrail verdicts. This allows for complex logic like fallbacks…

Hi HN! We just launched Codacy Guardrails, an IDE extension with a CLI for code analysis and MCP server that enforces security & quality rules on AI-generated code in real-time. It hooks into AI coding assistants (like VS Code Agent Mode, Cursor, Windsurf), silently scanning and fixing AI-suggested code that has vulnerabilities or violates your coding standards, while the code it’s being generated. We built this because coding agents can be a double-edged sword. They do boost productivity, but can easily introduce insecure or non-compliant code. One recent research team at NYU found that 40%…

Open-Source Gateway to Stop Tool-Abusing Prompt Injections2025 · archestra.ai · ▲9Hi HN, Matvey, Ildar, Joey, and Dominik here. If you're building LLM agents that use tools, you're probably worried about prompt injection attacks that can hijack those tools. We were too, and found that solutions like prompt-based filtering or secondary "guard" LLMs can be unreliable. Our thesis is that agent security should be handled at the network level between the agent and the LLM, just like a traditional web application firewall. So we built Archestra Platform: an open-source gateway that acts as a secure proxy for your AI agents. It's designed to be a deterministic firewall against…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
