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 DirectorColoClue 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!

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.
CTOIn our hyper-connected world, secure networks are critical to ensuring robust and reliable infrastructure worldwide. Arrcus strongly endorses the MANRS belief that security is a key tenet of the global network architecture - it has been a key guiding principle for us as we have built our ACE platform to support enterprise and service provider customers. Arrcus is proud to support MANRS and the important work being done developing standards to help ensure a more securely connected global internet.
