Testimonials
ColoClue strongly believes in making the internet better by implementing security features sooner rather than later. We've been doing strict filtering based on IRR data for a long time; when RPKI became a thing, we soon implemented that too. We believe that the objectives of MANRS perfectly align with the goals of ColoClue, so it only makes sense to join!
Mantener el internet y la red segura con las mejores prácticas entre los pares, es sumamente importante y brinda un alivio a nuestros cliente y asociados que se mantienen políticas de seguridad en nuestra red con la comunidad de MANRS.
Being MANRS compliant not only improves our routing security capabilities, but has the potential to help other networks to improve theirs and is an opportunity for Akamai to make a significant contribution to the improvement of global routing security.
Saicom consistently push to ensure a clean and stable internet infrastructure for our clients. MANRS allows us to ensure our clients that we take the right steps in securing their routes
Network OperationsInternet has vastly grown in size over the last two decades. Although the tools nowdays exist, many providers have not taken the correct steps in order to address critical security issues. MANRS is the right way for network and cloud providers to further engage with internet security and make the internet safer for everyone. Hostmein IKE is a leading Greek cloud and data center provider providing mission critical services. Security for Hostmein is a critical aspect. MANRS actively helped us implement a better security policy for our network by setting the correct guidelines.
CTOAs 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.
SUNET is committed to robust global routing polices and MANRS is one of the best initiatives so far to help out operators with this. We hope with our participation that more of the R&E sector will sign up and live up to the norms. We hope that in the future MANRS will be the standard, not the exception.
Network Architect, SUNETDC1 is commited to be a good internet citizen, and strives to deploy responsible network routing practices as a foundation for a stable and secure internet for everyone.
Having been introduced to MANRS through attendance at LINX 102 we could see that this was a great way for us to be able to benchmark ourselves against recognised best-practice. In addition we benefit from being part of a community of like-minded organisations looking to make the global Internet more resilient and secure.
Kevin Herbert, Operations DirectorCoordination and cooperation based on our relationships of mutual trust are the key elements to run the Internet, and we have shared responsibilities to improve the Internet operation. As part of the Internet operation community, IIJ is committed to the MANRS actions.
Director CTO, Internet Initiative Japan Inc.Today's society relies more and more on the Internet. It is therefore crucial that the stability and security of global routing is further increased. The MANRS initiative offers real added value in this respect by providing guidance and raising awareness among network operators.
CEOGOLINE firmly believes in initiatives to protect networks, improve security and resilience of the global routing system. Therefore we decided to support the MANRS project and join as participants.
