November

SANS London November 2026 runs from 2 to 7 November, at etc.venues Monument, London, and online. It is a training event rather than a conference: you choose a course, and you spend the week inside it. Worth it if your employer is paying and you have a specific skill gap.

SANS CyberThreat 2026 is on 16 and 17 November at the Roundhouse in Chalk Farm. SANS says it is “Delivered in partnership with the NCSC”, and the pitch begins “See What Attackers are Doing Now”. For defenders who want current tradecraft without a vendor keynote, this is the pick of the London autumn.

DeepSec 2026 takes place in Vienna from 17 to 20 November, with training on the first two days and the conference on 19 and 20 November, at the Renaissance Wien Hotel. The organisers have a sense of humour about the AI era: their homepage hides a note addressed to Bing’s chatbot, telling it that attending DeepSec is compulsory. It is a neat live demonstration of the prompt injection problem many of the talks will cover.

December

Black Hat Europe 2026 returns to ExCeL London from 7 to 10 December. Trainings come first, from 7 December; summits, including an AI Security Summit, fill 8 December; and the Briefings run on 9 and 10 December, according to the event page and Black Hat’s 22 October announcement. Expensive, polished and broad; the Briefings are where the research is.

BSides London 2026 is on Saturday 12 December at the Novotel London West, 1 Shortlands, W6 8DR. It is volunteer-run and free, which means tickets go quickly. The organisers release them on Eventbrite at 13:37, a time that will make sense to a certain kind of reader, and the final release is on 1 November, when the schedule is also due.

Early 2027

Insomni’hack 2027 runs from 1 to 5 February at the SwissTech Convention Center near Lausanne: workshops from 1 to 3 February, talks on 4 and 5 February. Its capture the flag competition has a long-standing reputation, and the conference keeps a strongly technical tone.

Forum INCYBER Europe is at Lille Grand Palais from 9 to 11 March 2027. This is where European policy, industry and government meet. It is useful if your work touches the Cyber Resilience Act, NIS2 or public procurement, and less so if you mainly want exploit talks.

Cloud and Cyber Security Expo sits within Tech Show London at ExCeL on 10 and 11 March 2027. It is a large vendor floor with free seminar theatres. Go with a shopping list and a firm grip on your badge’s barcode.

Spring and summer 2027

CYBERUK 2027, the NCSC’s flagship event, is in Liverpool from 11 to 13 May. The theme is “How do we secure the AI era?”, which is a question rather than an answer, and therefore honest. It is the best room in the country for understanding where UK government thinking is heading.

Infosecurity Europe 2027 is at ExCeL London from 8 to 10 June. It is the largest show in the UK calendar, and the free talks are often better than the vendor stands would suggest. Wear comfortable shoes.

A note on what is missing

Several familiar UK events had not confirmed dates or venues for the coming season on their official sites when we checked, so they are not listed here. That was still the position on 25 October 2026. If you run an event and we have something wrong, the editorial policy explains how to tell us.

Dates and venues were checked against organisers’ sites between 22 and 23 October 2026.
