PostClassical Security is written and maintained by Howard Poston — a cybersecurity security expert with a background in blockchain, machine learning, secure coding, and post-quantum cryptography.
Most security content focuses on present threats and best practices. This site looks at what's coming next in security: post-quantum cryptography, autonomous AI systems, and on-chain infrastructure.
Explore the shifts on your own schedule. Courses, reports, and notes you can access when you need them, with nothing to book or wait on. For work that doesn't fit a self-serve product, a short call or a live-delivered briefing is available on request — see Toolkits
Howard also develops security courses for platforms including Pluralsight, Coursera, and Infosec, and writes for select cybersecurity clients directly. If that's relevant to you, reach out via Contact.
