Europe’s security calendar runs on two tracks. One is the big trade show circuit, where CISOs, buyers and vendors meet across huge expo floors in London, Nuremberg and Brussels. The other is the research scene, where smaller, technical events in Berlin, Heidelberg and Paris draw exploit developers, red teamers and reverse engineers.
This guide covers both. We checked each organizer’s official site for 2027 dates and venues. Where an organizer has not yet published 2027 dates, we list the most recent verified edition so you can plan around the usual timing.
Budgets and travel days are limited, so the right mix depends on your role. A security leader shopping for platforms will get more from a trade show, while a researcher or pentester will get more from a single-track technical conference.
Cybersecurity Conferences In Europe In 2027 At A Glance
Infosecurity Europe is the UK’s flagship information security exhibition and conference, held each June at ExCeL London. It pairs a large vendor floor with keynote and strategy talks, which makes it the most efficient place in Europe to compare products across identity, cloud security, SecOps and data protection in a few days.
It suits CISOs, security architects, procurement teams and vendors planning their European pipeline. Book meetings ahead, because the floor is busy and exhibitor teams fill their calendars early. The 2027 edition runs 8 to 10 June 2027 at ExCeL London.
it-sa is the organizer’s self-described largest IT security trade fair in Europe, held at the NürnbergMesse exhibition center. The event has a strong German-speaking audience, with many sessions and stand conversations in German, and it attracts both established vendors and regional specialists.
Go if you sell into, or buy for, organizations in Germany, Austria and Switzerland. It is a good fit for IT security managers in the Mittelstand, public sector buyers and channel partners. it-sa 2027 runs 5 to 7 October 2027 in Nuremberg.

How To Choose A Cybersecurity Conference In Europe
Are You Buying, Selling Or Researching?
Trade shows such as Infosecurity Europe, it-sa and Cybersec Europe are built for product discovery and vendor meetings. Research events such as OffensiveCon, Hexacon and TROOPERS are built for technical learning. Decide which outcome matters most before you book, because one event rarely does both well.
Which Market Do You Need To Reach?
Regional focus matters in Europe. it-sa is strongest for the DACH market, Les Assises for France, Cybersec Europe for the Benelux and Infosecurity Europe for the UK. Check the language of the program as well, since some events run many sessions in German or French.
Do You Want Training As Well As Talks?
Black Hat Europe, TROOPERS and OffensiveCon all pair trainings with their main programs. If your team needs structured skill development, combining a course with the conference can justify the travel and keep everything to one trip.
How Will You Measure The Return?
Set a goal before you go, such as a target number of qualified meetings, a short list of vendors to evaluate or specific research areas to cover. Book meetings ahead of trade shows, and for community events plan which talks and villages you will prioritize.
Conclusion
Europe offers a security event for almost every role in 2027. Infosecurity Europe, it-sa and Cybersec Europe lead for buyers and vendors, INCYBER and Gartner serve leaders focused on policy and strategy, and TROOPERS, Hexacon and OffensiveCon reward technical practitioners. Community events such as BSides London and the Chaos Communication Congress round out the calendar.
Several organizers have not yet announced 2027 dates, so confirm details on each official site before booking travel. Pick two or three events that match your goals and market, and plan your meetings early.
