Meetings are normally the last Tuesday of the month, except December.

New attendees welcome, just come along! (There are no entry fees, and no tickets to book.)

If you’d like to be reminded of future events, add the ical feed to your calendar.


18+ Sorry, the pub’s license only allows people 18 and over after 6pm.

Please be respectful to our speakers, other attendees, and the venue staff.

Talk nights

Format is usually two talks: a primary 45 minutes (ish), and a secondary 30 minutes (ish). Talks start at 19:30, but we have the room from about 18:30 to 23:00.

Speakers Wanted

Typically our programme has a technical talk (~1 hr) and lighter talk (~30 min). Once or twice a year we have a “Lightning Talk” format, with shorter talks up to ~15 minutes, with anyone who wants to speak on the night.

The qualifications for speakers are simple, have a subject of interest to fellow technical & InfoSec people. The subject can be on technical or security issues, social interaction with technology, based on the current events, or just something entertaining to our attendees. As a speaker you can be an expert, a student, someone learning a new area, maybe a regular speaker on the conference circuit, but we also love to have new & occasional speakers.

Send your talk / activity proposals to talks@dc4420.org

You are very welcome to propose running activities other than talks, such as hands-on workshop or an infosec pub quiz, or something else relevant to our techie audience!

We also welcome occasional company pitches, to sell or recruit, but to regulate the frequency of these we ask you to buy a round of drinks. Also please discuss with Major Malfunction or Tony beforehand!
