TSD began as an internal newsletter that our Security Lead, Daniel Tobin, would circulate to the team each Tuesday. It proved to be a great resource for all of us so we thought, why not share it with all of you? Our hope is that it helps make you just a bit more secure.

Check back here every Tuesday for more TSD or sign up below to stay in the loop!
