The 15 Best Cybersecurity Conferences in 2025
Every year we survey our newsletter subscribers and cross-reference with our own event attendance to rank the security conferences that consistently deliver value. This list prioritizes depth of content, networking quality, and practical takeaways over sheer size or marketing hype.
1. RSA Conference
San Francisco, CA · Spring
The largest security conference in the world, and it holds that position for a reason. The signal-to-noise ratio on the expo floor can be rough, but the keynotes, Innovation Sandbox, and the density of side meetings make it indispensable for anyone in a buying or leadership role. The peer-reviewed track has improved in recent years.
2. Black Hat USA
Las Vegas, NV · August
The gold standard for technical security research. The briefings are peer-reviewed, and the accepted talks routinely break new ground. The training days preceding the main conference are consistently excellent, though expensive. Skip the business hall if you're attending for the research.
3. DEF CON
Las Vegas, NV · August
The longest-running hacker conference in the world maintains its identity despite growing well past 30,000 attendees. The villages — focused spaces for car hacking, voting machine security, lockpicking, and more — are the main draw. Bring cash, patience, and a burner phone.
4. BSides Las Vegas
Las Vegas, NV · August
Runs alongside Black Hat and DEF CON, and many attendees consider it the best of the three. Smaller, more approachable, and free. Talks are selected from community submissions, and the quality is consistently high. The proving ground for speakers before they hit the bigger stages.
5. SANS Summits
Various locations · Year-round
SANS runs multiple focused summits throughout the year on topics like threat hunting, cloud security, DFIR, and ICS. The training is world-class but priced accordingly. The summits themselves offer excellent focused content and attract practitioners who are deep in their specialty.
6. Gartner Security & Risk Management Summit
National Harbor, MD · June
The conference for CISOs, security directors, and risk managers. Heavily analyst-driven, which can feel prescriptive, but the peer networking sessions and one-on-one analyst meetings provide genuine strategic value. Not a technical conference — attend for the leadership perspective.
7. Black Hat Europe
London, UK · November
Smaller than the US edition but with a strong European research community presence. The talks tend to include more policy-oriented content alongside the technical research. A good option if you're based in Europe or want a less overwhelming version of the Black Hat experience.
8. CanSecWest
Vancouver, BC · March
Home of the Pwn2Own competition, which alone makes it worth following even if you can't attend. The conference itself is smaller and focused, with a strong offensive security bent. The Vancouver setting doesn't hurt either.
9. (ISC)² Security Congress
Various locations · October
Oriented toward the CISSP and certified professional community, but the content has broadened in recent years. Strong programming for security managers and governance professionals. The CPE credits are a significant draw for attendees maintaining certifications.
10. OWASP Global AppSec
Various locations · Year-round
The application security community's main gathering. Content ranges from deeply technical code-level security to AppSec program management. The OWASP community is among the most welcoming in the industry, making this a particularly good conference for newcomers.
11. Infosecurity Europe
London, UK · June
The largest dedicated security event in Europe. The expo component is massive, and the conference program covers a broad range of topics. Particularly strong for professionals focused on the European regulatory landscape, including GDPR enforcement and NIS2.
12. ShmooCon
Washington, DC · January
A smaller, community-driven conference with a loyal following. Tickets sell out within seconds, which says something about the reputation. The talks blend technical research, policy, and culture. The DC location attracts a strong government and policy contingent.
13. Hack In The Box
Amsterdam, NL / Various · Year-round
Technical security conference with editions in Amsterdam, Dubai, and other locations. The Amsterdam edition is the flagship, and the training courses attract attendees from across Europe and beyond. Known for strong CTF competitions.
14. SecTor
Toronto, CA · October
Canada's largest security conference has built a reputation for quality that extends well beyond its regional roots. The single-track format for keynotes and a multi-track program for breakouts keeps things focused. Excellent networking in a manageable-sized event.
15. Virus Bulletin Conference
Various locations · September/October
The longest-running security conference focused on threat intelligence and malware research. Attracts the AV and threat research community specifically. The papers are published and peer-reviewed, making VB a genuine academic-quality venue within the security industry.
Honorable Mentions
Several events narrowly missed our list this year: CyberUK (NCSC's annual conference in the UK), Troopers (Heidelberg, Germany), NorthSec (Montreal), and the various regional BSides events — many of which punch well above their weight for free community conferences.
