AI Security Focus Areas

LLM & Application Security

Securing large language model applications against the OWASP LLM Top 10 - prompt injection, data leakage, insecure output handling, and model abuse.

Agentic AI Security

Threat modeling autonomous AI agents: tool abuse, the lethal trifecta, excessive agency, and turning untrusted text into remote code execution.

Model Context Protocol (MCP) Security

Defending the AI tool-integration layer against tool poisoning, supply-chain attacks, and malicious MCP servers.

RAG & Knowledge-Base Security

Hardening retrieval-augmented generation pipelines, vector databases, and the data that feeds enterprise AI.

AI Red Teaming

Adversarial testing of AI systems to surface jailbreaks, injection paths, and failure modes before attackers do.

AI Governance & Compliance

Translating the EU AI Act, executive orders, and emerging regulation into practical controls for high-risk AI systems.

Your Next Direct Report Never Sleeps: The Always-On Agent Era Just Began

Microsoft's Scout, NVIDIA and ServiceNow's Project Arc, and Google's Gemini Enterprise all landed within weeks of each other, and they share one trait that breaks every assumption in your AI rollout: they act without being asked. The shift from responsive assistants to always-on agents is not a feature upgrade. It is an org-design and governance problem that most leaders have not scoped. Here is how to think about it before it thinks for you.

72% in Production, 60% Ungoverned: The Agentic AI Gap Nobody Is Pricing In

Agentic AI hit 72% enterprise production adoption in 2026, yet a 60% governance gap trails right behind it, and Gartner expects more than 40% of agentic projects to be cancelled by 2027. The bottleneck is no longer whether agents work. It is whether anyone can prove they are safe, in scope, and worth the spend. Here is what the data shows and how to build the governance layer before it is forced on you.

The Lethal Trifecta: Why Your Most Useful AI Agent Is One Bad Email Away From a Breach

Simon Willison named the pattern: an agent with private data access, exposure to untrusted text, and a way to send data out is exploitable by design. EchoLeak and GeminiJack turned that pattern into working attacks against Microsoft 365 Copilot and Google Gemini Enterprise. The fix is not a better prompt. It is removing one leg of the triangle.

When a Prompt Becomes a Shell: Agent Frameworks Are Turning Text Into RCE

Microsoft just traced two prompt injections in Semantic Kernel all the way to host-level code execution. One prompt launched calc.exe. Another wrote a payload to the Windows Startup folder and escaped the container sandbox. The takeaway is blunt: your LLM is not a security boundary, and the tools you expose define your attacker's reach.

The $500 Million AI Bill Nobody Threat-Modeled

One company torched roughly $500 million in AI spend in a single month, and the scary part is not the number. It is that nobody noticed until the invoice landed. An agent with no spending guardrail is the same design flaw as an agent with no access guardrail.

Your AI Coding Agent Will Hand Over Your Machine. SymJack and TrustFall Just Proved It

Two vulnerability classes disclosed in the last two weeks broke nearly every major AI coding agent at once. SymJack makes the approval dialog lie. TrustFall removes the human entirely. The problem is not one product. It is the trust model the whole category shares.

The Government Just Called AI a Cyber Weapon. Your Threat Model Hasn't Caught Up

On June 2 the White House signed an order asking AI labs to submit frontier models for pre-release testing of their advanced cyber capabilities. You do not build an evaluation pipeline for a capability you think is hypothetical. The order is an admission. Enterprise defenders should read it as one.

Your AppSec Program Will Stall in Year Two. Here's Why

Year one of an AppSec program feels productive: scanners deploy, champions emerge, dashboards impress leadership. Then around month thirteen the energy dissipates, the backlog stops shrinking, and the program hits a wall. Here is why it happens and how to plan for it.

MCP Poisoning: The Supply Chain Attack Hiding Inside Your AI Agent

MCP tool poisoning has gone from theoretical research to documented supply chain incidents affecting hundreds of thousands of deployments. With CVE-2025-54136 exposing remote code execution in Cursor IDE and confirmed registry poisoning across 9 of 11 MCP platforms, this is the most urgent unresolved attack surface in enterprise AI. Here is what it is, what has already happened, and how to actually defend against it.
