A Guide to Europe’s Big Cybersecurity Conferences in 2026

Cybersecurity is not just a job title. It is a constantly moving field. New threats, tools, regulations and techniques appear every year, and one of the best ways to stay current is to step outside day-to-day work and learn directly from peers, researchers and practitioners.

Below is a curated overview of some of the most well-known cybersecurity conferences taking place across Europe in 2026. The focus is on events with strong reputations, real technical or strategic content, and consistent attendance from the security community.

Early Spring Conferences (March to April)

RootedCON

Madrid, Spain | March 5–7, 2026

RootedCON is one of the most respected cybersecurity conferences in Southern Europe. It is especially well known for its technical depth, hands-on workshops, and strong hacker culture. The audience is largely made up of practitioners, researchers, and engineers, which gives the event a grounded and practical feel.

The Future of Cyber Security Europe

London, United Kingdom | March 12, 2026

This is a one-day conference aimed primarily at security leaders and decision-makers. Topics typically focus on emerging threats, regulation, and long-term security strategy rather than deep technical material.

European Cybersecurity Certification Conference

Ayia Napa, Cyprus | April 15, 2026

Organised by ENISA, the EU Agency for Cybersecurity, this conference focuses on European certification schemes, standards, and regulatory frameworks. It is particularly relevant for professionals working with compliance, policy, or cross-border security initiatives within the EU.

Late Spring and Early Summer (May to June)

Cybersec Europe

Brussels, Belgium | May 20–21, 2026

Cybersec Europe brings together technical professionals, security managers, and vendors. The agenda usually spans cloud security, threat intelligence, operational technology, and incident response, making it a good all-round event for mixed audiences.

CyberWiseCon Europe

Vilnius, Lithuania | May 19–22, 2026

This multi-day event combines workshops with conference sessions. It is positioned as an educational conference, covering both fundamentals and current threat trends such as ransomware, AI-driven attacks, and ethical hacking practices.

Span Cyber Security Arena

Poreč, Croatia | May 20–22, 2026

Span Cyber Security Arena focuses on core cybersecurity practices, regulatory requirements, and defensive strategies. It is slightly smaller in scale than some other European conferences, which often makes it easier to network and have in-depth conversations.

CyCon: International Conference on Cyber Conflict

Tallinn, Estonia | May 26–29, 2026

CyCon is hosted by NATO’s Cooperative Cyber Defence Centre of Excellence. It stands out for its blend of technical research, military and national-level cyber defence discussions, and policy analysis. It is particularly relevant for those interested in cyber conflict, defence strategy, and international security.

Infosecurity Europe

London, United Kingdom | June 2–4, 2026

Infosecurity Europe is one of the largest cybersecurity events on the continent. It attracts thousands of attendees and covers everything from governance and risk management to technical tooling and training sessions. It is also a major networking hub for the European security industry.

Autumn and End-of-Year Events

Cyber Security and Cloud Expo Europe

Amsterdam, Netherlands | October 2026

Part of the TechEx event series, this conference focuses on enterprise security, cloud infrastructure, and large-scale systems. It is especially useful for professionals working in complex or highly regulated environments.

Black Hat Europe

London, United Kingdom | December 7–10, 2026

Black Hat Europe is one of the most prestigious technical security conferences in the world. It is known for high-quality research briefings and intensive hands-on training sessions. Attendance includes experienced practitioners, researchers, and security teams from major organisations.

Why These Conferences Matter

Attending cybersecurity conferences offers benefits that are hard to replicate through online content alone:

You can benchmark your knowledge against peers and experts
You see tools, research, and techniques demonstrated in real scenarios
You can ask direct questions to researchers, engineers, and policy makers
You build professional connections that often last well beyond the event

Alongside these major conferences, Europe also hosts smaller regional meetups, capture-the-flag competitions, and specialist events focused on identity, cloud, or industrial security. These can be valuable additions depending on your area of interest. If we missed any European cybersecurity conferences that deserve a spot here, don’t hesitate to send us a message.
