Below is the 2023 cohort of the MANRS Mentors and Ambassadors Program, who will work to make the global routing infrastructure more robust and secure.

Mentors — well-respected routing security professionals – help guide Ambassadors — emerging leaders — to improve their skills while working together in their regions and industries.

During the six-month program (June to December), the Mentors and Ambassadors will work across the MANRS training, research, or policy tracks.
