Why Everyone Needs a Blog | THE IDEA SERIES

🔹 Thanks to ProjectDiscovery for sponsoring today’s video. I've been using their tools like Nuclei and Subfinder for years, and now they’ve brought that power to the cloud with a full vulnerability management platform.

For over a decade, I've been exploring how AI and context intersect—and I believe Unified Entity Context (UEC) is the key to unlocking what comes next.

In this podcast, I walk through my journey—from security assessments and AI-powered tools to building real-world demos like Alma and Threshold. The core idea? That most hard decisions are only hard because we lack the necessary context. With rich, accurate, and fresh context, even complex decisions become simple.

If you're building in security, investing in AI, or just trying to understand where things are heading, this concept might reframe everything.

What really happened at RSA 2024?

Daniel Miessler and Jason Haddix break it down.

Fresh off a whirlwind RSA week, Daniel sits down with Jason Haddix (Arcanum Information Security) to talk about what mattered—beyond the show floor noise. From off-site innovation summits to real-world AI implementation, this deep dive covers:

-Where the real innovation happened (hint: not on the show floor)
-Key takeaways from the OpenAI and Airbnb AI Security events
-Jason’s talk on AI pentesting methodology and the Prompt Injection Taxonomy 
-The future of cybersecurity moats and the risk of AI-native disruption 
-Why agents aren’t the main character—data is -DARPA's AIxCC competition and the rise of Cyber Reasoning Systems 
-Challenges with evals, autonomous security workflows, and VDP backlash -Behind the scenes at RSA: puppies, parties, burnout, and brutal honesty

They also explore content creation, the future of platform-native context, and why being opinionated (with receipts) matters more than ever in security and tech.

➡ Get full visibility, risk insights, red teaming, and governance for your AI models, AI agents, RAGs, and more—so you can securely deploy AI powered applications with ul.live/mend

In this episode, I speak with Bar-El Tayouri, Head of AI Security at Mend.io, about the rapidly evolving landscape of application and AI security—especially as multi-agent systems and fuzzy interfaces redefine the attack surface.

We talk about:

• Modern AppSec Meets AI Agents
 How traditional AppSec falls short when it comes to AI-era components like agents, MCP servers, system prompts, and model artifacts—and why security now depends on mapping, monitoring, and understanding this entire stack.

•  Threat Discovery, Simulation, and Mitigation
 How Mend’s AI security suite identifies unknown AI usage across an org, simulates dynamic attacks (like prompt injection via PDFs), and provides developers with precise, in-code guidance to reduce risk without slowing innovation.

•  Why We’re Rethinking Identity, Risk, and Governance
Why securing AI systems isn’t just about new threats—it’s about re-implementing old lessons: identity access, separation of duties, and system modeling. And why every CISO needs to integrate security into the dev workflow instead of relying on blunt-force blocking.
