About
CyCon 2027, the International Conference on Cyber Conflict, is the annual flagship event of the NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE). It is a multidisciplinary cybersecurity conference that examines cyber defence through technical, legal, policy, strategic and military lenses, with original academic research at its core. The 19th edition is scheduled in person in Tallinn, Estonia, from 25 to 28 May 2027 under the theme "Unified Response." According to the organizers, CyCon draws more than 600 attendees each year, including decision-makers, legal and technology experts and representatives of governments, armed forces, academia and industry from nearly 50 countries. The program typically features keynote speeches, plenary sessions, focused panels, breakout discussions and workshops covering malware and technology development, education and training, legal questions and hands-on practical exercises, with peer-reviewed proceedings published alongside the event.

Travel questions? See Good to know in the travel guide below.
Planning your trip to Tallinn
Contains sponsored linksTallinn holds one of the best-preserved medieval old towns in northern Europe inside a state that runs almost entirely on digital public services, which makes it a fitting seat for a cyber conflict conference. Late May brings long Baltic evenings and temperatures that finally justify the terraces on Town Hall Square. Beyond the city walls, Kalamaja's wooden houses and the Soviet-era seaplane hangars give a much less picturesque read of the place.
Getting there & around
Tallinn Airport (TLL) is unusually close to the centre, about ten minutes by tram line 4 or by taxi. Ferries from Helsinki cross in roughly two hours and dock within walking distance of the old town. The compact centre needs no transport at all; trams and buses cover the outer districts, and public transport is free for registered residents but paid for visitors.
Skip the taxi queue — pre-book a fixed-price airport transfer with Kiwitaxi. Exploring beyond the city? compare rental cars on EconomyBookings.
Staying connected
Estonia has dense, fast coverage and public Wi-Fi is close to universal, a legacy of early national investment. An eSIM covers arrivals cleanly, particularly for delegates continuing on to Helsinki or Riga where roaming rules may differ. Set up an eSIM with Airalo before you board and you're online the moment you land.
After the sessions
Toompea and the old town walls. The upper town on its limestone outcrop holds the parliament, the onion-domed Alexander Nevsky Cathedral and two viewing terraces over the red roofs below. The lower town spreads out from Town Hall Square. Walk the surviving wall towers. Two hours for both levels. Tickets on Tiqets →
Kalamaja and Telliskivi. A former fishing and industrial district just north of the walls, with painted wooden houses and a converted factory complex now holding studios, food halls and a street art precinct. It is where the city's contemporary life actually happens. Twenty minutes on foot. An evening.
Seaplane Harbour. A maritime museum inside vast 1916 concrete seaplane hangars, holding a complete submarine that visitors walk through, plus icebreakers moored outside. The building's engineering is as notable as the collection. On the waterfront north of Kalamaja. Two hours. Tickets on Tiqets →
Kadriorg Park and Palace. A baroque palace and formal gardens commissioned by Peter the Great, now housing a foreign art collection, with the modern national art museum nearby in the same park. Twenty minutes by tram east of the centre. Pleasant in late May light. A half day for both.
Good to know
How far is the airport from the old town?
Roughly ten minutes. Tram line 4 runs from the terminal to the centre, and taxis are inexpensive over that distance.
Is a day trip to Helsinki practical?
Yes. Ferries cross in about two hours each way and run frequently, making a long day trip realistic from a Tallinn base.
What is the weather like in late May?
Cool to mild with very long daylight, and a persistent wind off the Baltic. Evenings need a jacket even after warm afternoons.
