PostClassical Security is written and maintained by Howard Poston — a cybersecurity and blockchain security expert with a background in malware analysis, secure coding, and post-quantum cryptography.
Most security content explains what already broke. This site exists to cover what's about to — post-quantum cryptography, autonomous AI systems, and on-chain infrastructure — before it's mainstream enough that everyone's writing about it.
Everything here is self-serve by default: courses, reports, and notes you work through on your own schedule, 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 — but using anything on this site never requires scheduling anything.
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.
