A Colorado Springs chapter of OWASP (Open Web Application Security Project) is starting up, and for Peak PHP's October meeting we're going to attend the OWASP kickoff!
Details can be found here: https://www.meetup.com/OWASP-Colorado-Springs-Meetup/events/254789897/
It's a bit earlier than our normal meeting time (5:30pm), and of course the venue is different (523 South Cascade Avenue · Colorado Springs)
Give me a shout if you have any questions. Hope to see you there.
