Field notes
- HOU.SEC.CON was renamed CYBR.SEC.CON in 2026; older listings under the old name refer to the same conference.
- Houston's DEF CON groups (DC713, DC281, DC936, DC409) and Hacking Club post meeting venues on Discord rather than on their websites. DC281 keeps a shared calendar of Houston hacker meetups at dc281.org/cal. DC936 is listed as dormant only because its last dated meeting on that calendar is from April 2025.
- Houston Locksport skipped its September 16, 2026 social because it ran a lockpicking area at CYBR.SEC.CON the day before.
- OWASP Houston has two Meetup groups; the active one is meetup.com/owasp-houston-texas-chapter, which has held no event since August 2025.
- Several Houston conferences (the Official Cybersecurity Summit, CS4CA, the Texas Technology Summit, ElevateIT, SecureWorld and CYBR.SEC.CON) are run by events businesses and funded by vendor sponsors.
