Starting off the year with the uno reverse card 🤣🤣🤣

LONDON, BABY!

I'm bringing my course "Building a High-Value AppSec Scanning Programme" to London as part of @owasp's London training days, 23-24 February 2026.

As seen at OWASP Global conferences, @BlackHatEvents and @NDC_Conferences, don't miss your chance to attend!

About to head home after a packed week+ in Vegas for Hacker Summer Camp.

Some highlights for me:

My searing hot take for today is that everyone hitting out at "security influencer" culture might want to consider that being able to persuade and influence is probably the most important tool in your security skillset.
Excited to be back delivering my course again at Black Hat USA!

The final two parts of my blog series about delivering training at conferences have now been released!

You can check them out on the @BounceSecurity website now!

Pulled last year's class workbook out so that I can prepare the updated version for this year.

You still have time to sign up for my updated course at @BlackHatEvents #BHUSA, in person in Las Vegas, August 4-5.
