Director, Security Strategy, VerisignPIT Bolivia’s vision is to be a point of reference in the digital environment that contributes to the improvement of the Internet in Bolivia. For this it is vital to implement good international practices to ensure routing between the different Internet agents in Bolivia that exchange traffic.
General manager, PIT BoliviaAs the provider of a network that connects NZ's researchers, educators, and students to the rest of the world, REANNZ has always taken the security and stability of our members’ networks seriously. MANRS’ pragmatic and straightforward framework for implementing best practice routing security reflects and expands upon our own efforts in this area. We support this initiative and encourage wider adoption of it throughout the Internet community for the benefit of all.
For Arista, security is a key attribute of our overall solution, starting at the routing perimeter for worldwide Internet resiliency. As a global industry leader in cloud networking, we want to take part in the efforts to secure the Internet as well. MANRS is providing great guidelines to achieve that goal and Arista Networks is proud to be a founding participant of the MANRS Vendor Program.
Senior Vice President, Customer Engineering for Arista Networks1&1 Internet is committed to responsible network routing practices and robust global routing policies as a foundation of a resilient Internet. MANRS is a great initiative to help operators live up to the necessary standards.
Head of Network Engineering at 1&1 InternetGood network routing practice is the fundamental requirement for trust between providers, and ultimately creates a safer and stronger internet for customers. KPN is committed to providing secure and trustworthy communications, and by joining partners in MANRS, we continue to improve security and resiliency for all.
Chief Information Security Officer, KPNWe believe the security, stability, and resiliency of the Internet operation can be improved via distributed and shared responsibilities as documented in MANRS. As one of the largest academic networks in the world, CERNET is committed to the MANRS actions.
Deputy Director, CERNETAnexia believes that routing security is imperative for the sustainability of the global communications network. By joining MANRS we express our intent to contribute to a trustworthy environment for all participants.
Senior Network Engineer, IP EngineeringMaintaining routing security hygiene is one of the most important aspects for a resilient Critical Internet Infrastructure implementation. Being a community IX, joining the MANRS program and implementing best practices will go a long way in propagating the change within the community. Joining MANRS and also working with our peers advocating the best practices are one of the key agendas towards a more secured Internet experience in the region.
