I look forward to this show every week.

Steve Gibson is legendary and he really knows his stuff - who else could code so well (in assembler) AND develop security solutions which are ahead of their time and GIVE AWAY so many utilities at his site GRC dot com.

Leo Laporte brings some extra spark to the show - as he does across the TWIT (This Week in Technology) network

The only possible non-positive thing to sag might be that they are rather US West Coast - being in California it’s to be expected :)

Thanks to Steve and Leo for informing, educating and entertaining every week for over 1000 shows!

Relatable cyber security for techies and humans too ;)
