This site could be described as the gateway to the various bits of Small Blue-Green World, which is essentially me wearing my business hat. While it refers to sites and organizations to which I’ve contributed content and other services, this blog is completely independent, is not sponsored, and represents no organization or individual but me.

As of 31st December 2018, I no longer have a permanent role in the security industry, but might be tempted by the occasional editing/reviewing job. (See contact form.)
