Just got back from the shelter and I can't believe this little guy is officially mine! 🐶 Meet Biscuit — the newest member of the Webb household. He's already figured out how to steal my spot on the couch. Life is good! 🥰 #AdoptDontShop #DogDad #NewPuppy

Great session at the Austin Security Summit today. Tons of excellent talks on zero-trust architecture and network segmentation. Reminded me why I love this field. If you missed it, definitely check out the recordings when they drop. #Cybersecurity #ZeroTrust #Networking

Was back in Denton this weekend visiting family. Nothing beats going back to your hometown and realizing how much it's grown. The square is unrecognizable! Austin is home now but Denton will always have a piece of my heart. 🤠 #TexasForever #Denton
