In IT? Do you have 5 minutes?
Concise, Effective, Timely The perfect podcast, Johannes is amazing. This must take him hours every day to research. The effort is much appreciated!

Best in Show!
Johannes delivers just the right amount of daily relevant information to stay aware of threats and risks, as well as the occasional research/whitepaper topic. Bravo!

High quality info in a short amount of time. Listen very closely to what he puts out
Johannes continues to point out trends and indicators I might otherwise have missed. I’ve seen a lot of crazy scenarios play out based on data he’s gathered and provided. Listen to a few episodes to hear what I mean. His podcast also serves as a convenient reminder for Patch Tuesday and iOS updates. Yet another great podcast the sociable Dave Bittner has led me to.

Required Professional Daily Use
This is a requirement for my team as they start their day. The information is a great way to start the brain thinking into what is going on and what new things should we be looking for. We discuss it and volunteer topics for research and further discovery. 11/10 -highly recommended
