LLM Security

PromptShield is a prompt injection scanner that audits repositories for malicious instructions and hidden Unicode before AI agents ever consume them. It statically scans agent instruction files, detects zero-width character attacks and taint patterns, and maps findings to the OWASP Agentic Top 10 (2026) so teams can block supply-chain and prompt-injection risk in CI/CD. What Is PromptShield and Why Repo Scanning Matters PromptShield belongs to a fast-growing category of tools built to answer one uncomfortable question: can you trust the instructions your AI agent is about to read? As coding agents like Claude Code, Codex, and Cursor become the default way teams ship software, the files those agents read — READMEs, AGENTS.md files, MCP configurations, and skill definitions — have become a new attack surface. ...

The All-AI-Jailbreaks repository is a curated, actively maintained archive of 19 prompt-injection and jailbreak experiment files spanning at least nine major model families, including DeepSeek, Gemini, GLM, Grok, Kimi, Qwen, Sonnet, ChatGPT, and Antigravity. It is best understood not as a “how to jailbreak” list but as a structured red-teaming corpus that maps directly onto the OWASP Top 10 for LLM Applications, where prompt injection ranks as LLM01:2025 — the number-one vulnerability in the industry. This review explains what the archive contains, how its five research themes align with the OWASP taxonomy, and how it fits the broader 2026 AI-security ecosystem of automated red-teaming frameworks and defensive proxies. ...

Cisco AI Defense is the enterprise platform that secures AI agents and LLM applications by enforcing security at the network level — without requiring code changes from developers. If you’re an engineering or security team deploying agentic AI in 2026, this is the most comprehensive platform on the market for addressing the full attack surface: model vulnerabilities, prompt injection, MCP protocol abuse, agent-to-agent trust chains, and AI supply chain transparency. ...

Autonomous AI agents are executing real actions — writing code, querying databases, sending emails, and calling third-party APIs — and the security industry is finally treating them as the high-value attack surface they represent. The AI security market is projected to reach $12.8B by 2026 at a 28% CAGR, driven almost entirely by enterprise urgency around agent deployments. Unlike traditional software vulnerabilities, AI agent attacks are often semantic rather than syntactic: a well-crafted prompt in a retrieved document can silently redirect an agent’s entire task chain without triggering a single firewall rule. Security teams that treat agents like ordinary microservices will discover this difference the hard way. ...
