Solution to AI Agent Prompt Injection, Hijacking attacks and Info Leaks:

Solution to AI Agent Prompt Injection, Hijacking attacks and Info Leaks: AI agents can be hijacked mid-task through the content they process. Every existing defense operates at the reasoning layer and can be bypassed. Sentinel enforces at the exe…

We built a cryptographic authorization gateway for AI agents and planning to run limited red-team sessions

Hi , I’m the founder of Sentinel Gateway. We’ve been focused on the structural problem of instruction provenance in autonomous agents: models process all text as undifferentiated input, so adversarial content can cause agents to propose harmful actions…

AI Agent Security Without Content Filtering, A Different Architecture

Sentinel Gateway, a middleware platform that solves prompt injection at the infrastructure level by cryptographically separating instruction and data channels, so the model never decides what qualifies as a command. Every agent action is also governed …

Prompt Injection and Info Leak Immune AI Agent, working Demo for Testing

Prompt injection is ranked the #1 security vulnerability for AI agents by OWASP and current solutions are not working. Sentinel Gateway takes a fundamentally different architectural approach to the problem, and we have a working prototype tested agains…

Introducing Open Book Medical AI: Deterministic Knowledge Graph + Compact LLM

Introducing Open Book Medical AI: Deterministic Knowledge Graph + Compact LLM Most medical AI systems today rely heavily on large, opaque language models. They are powerful, but probabilistic, difficult to audit, and expensive to deploy. We’ve taken a …

Trustworthy AI Through Knowledge Graphs + RAG Audit

AI with minimum hallucinations and an output that can be audited. How by using Knowledge Graph as source of truth and RAG for answer audit First practical application medical field, end result an AI that's capable of clinical diagnosis and can ass…

Medical AI with Knowledge-Graph Core Anchor and RAG Answer Auditing

Medical AI with Knowledge-Graph Core Anchor and RAG Answer Auditing A medical knowledge graph containing ~5,000 nodes, with medical terms organized into 7 main and 2 sub-categories: diseases, symptoms, treatments, risk factors, diagnostic tests, body p…

AI Fatigue?

I am relatively new to this group and based on my limited interaction, feeling quite bit of AI sceptism and fatigue here. I expected to meet industry insiders and members who are excited about hearing new developments or ideas about AI, but its not eve…

Beyond LLMs: Real Path to GenAI

I’ve been experimenting with a slightly different approach to AI, and I’d genuinely value feedback from people working in ML, health IT, or clinical education. Instead of scaling parameters, I built a compact medical SLM (6GB) that’s tightly coupled to…
