In October, 2021, we released 4.0.3 of the OWASP ASVS Standard. This release marked the start of the Vanilla Ice (or 5.0 as everyone else called it) release.
A major rethink about how we use the standard and with feedback from the community.

So, you've decided you want to deliver training courses at a conference?
In the next post in my series about my experiences, I want to talk about money. I don't think it should be your main motivation but you probably can't ignore it!

I will be publishing the next post in this series tomorrow so look out for it!
This year should hopefully be the 3rd year that I train at @BlackHatEvents #BHUSA and also at @OWASP #AppSecEU?
But how did I get to this stage?
The short answer is a lot of thought and hard work.
And the long answer?
