- Founder and Chief Innovation Officer of SSH Communications Security
- Board member since 1995
While working as a researcher at Helsinki University of Technology, Tatu Ylönen began working on a solution to combat a password-sniffing attack that targeted the university's networks. What resulted was the development of the Secure Shell (SSH), a security technology that would quickly replace vulnerable rlogin, TELNET, and rsh protocols as the gold-standard for data-in-transit security.
Tatu has been a key driver in the emergence of security technology including SSH & SFTP protocols and co-author of globally recognized IETF standards. He has been with SSH Communications Security since its inception in 1995 holding various roles including CEO and CTO and as a Board Member.
In October 2011, Tatu returned as the Chief Executive Officer of SSH Communications Security, bringing his exceptional experience as a security innovator to the company's product line. In October 2014, he changed to the role of Chief Innovation Officer in order to be able to focus more on the technology-side of the business. In this role, he is responsible for selected new product concepts, the company's intellectual property development, and various other strategic initiatives.
Tatu holds a Master of Science degree from Aalto University, Finland.
