My name is Sean Gallagher.

I am a security researcher.  I’ve been an information technology journalist, researcher and practitioner since before Al Gore invented the Internet. Prior to that I was an officer in the US Navy, and served aboard USS Iowa and with a Special Boat squadron as a junior staff officer.

I now work for Cisco’s Talos Threat Intelligence and Interdiction team. If you are trying to reach me regarding my current work, contact Cisco corporate public relations. If this is about something else, use the form below to send me a message.
