Philosophy at work, Cybersecurity in action
AI safety,grounded in security.
I'm Ricardo Prieto, a cybersecurity practitioner focusing my career on AI safety. I want to help make increasingly capable AI systems useful, secure and subject to meaningful human control.
PhiloCyber is where I share my writing, talks, and practical resources as I work toward contributing to AI safety research more meaningfully.
Useful AI • Safety • Human control
Security experience • Public work • Research skills in development
London made the purpose clear.
I was already working on the security of AI applications when I attended the AI Security Bootcamp (AISB) in London. The experience made me think more deeply about the safety of increasingly capable systems, the evidence behind deployment decisions and how people can retain meaningful control. I came back believing I had found the work I want to dedicate my life to.
PhiloCyber is changing with that decision. The security experience that brought me here is the foundation I want to build on.

Selected writing
Three pieces selected from the archive for their connection to the work I'm carrying forward.
What I'm focusing on now
I'm finishing the public resources already underway while strengthening my machine-learning foundations and research skills. Original AI safety research is a direction I intend to grow into, with questions and claims documented only when the work exists.
Have a joint project, role, interview or useful piece of feedback in mind?
I'm open to research, fellowship, employment, speaking, press and community conversations, plus useful feedback on the guide and tools. PhiloCyber is no longer taking new consultancy engagements.
