Jersey City, NJ cybersecurity events & groups
Jersey City has little security programming of its own: its DEF CON group, DC201, last posted a meeting in July 2022, and most in-city activity is student-led, including the Hudson County Community College cybersecurity club and the ISC2 New Jersey chapter's free CTF for Novices at Saint Peter's University on November 14, 2026. Regular meetups are across the river in Manhattan (NYC2600 on first Fridays, NYSEC on third Tuesdays, OWASP NYC, DC212) or in North Jersey (DC862, DC908 at the Westfield library). The main fall conferences are SecureWorld New York City on October 29, 2026 and the NY Metro Joint Cyber Security Conference on November 5, 2026.
