Advisory, research, and community for the people building and defending AI systems. Weekly briefing, Slack community, and hands-on consulting from a SANS Faculty Fellow with 20 years in the field.
Helping organizations figure out their AI risk posture, build security into AI-powered products, and make sense of a vendor landscape that changes every week. Strategy, architecture review, and hands-on guidance from someone who teaches this stuff for a living.
Curated AI security news, original analysis, and practical frameworks. Not a link dump. Each issue will include opinionated takes on what matters, what's noise, and what you should actually do about it.
A place to discuss newsletter topics, share findings, and connect with other security professionals working on AI risk. SEC411 students get access to private channels with course support, Q&A, and direct help from Seth.
I'm Seth Misenar. I've spent 20 years in information security: building detection pipelines, breaking into systems, and teaching practitioners how to do both. I'm a SANS Faculty Fellow and lead author for SEC411 (AI Security Principles and Practices), and a coauthor on SEC511 and LDR414. I also advise on AI security strategy through Context Security.
This site exists because AI security is moving faster than any training course can keep up with. I needed a way to share what I'm seeing in real time with the people who need it most: the practitioners on the ground doing the actual work.
