Testimonials
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 DirectorWe at Brphonia understand and contribute to the dissemination of good practices, which makes the internet safer for us and our customers. Given this importance, we join the MANRS partners.
Network AnalystMazeda Networks has endeavored to keep up a safe and flexible network, conveying the most refreshed prescribed procedures and, as a National ISP Network, spreading them to its clients so as to get from them a dedication of sending these accepted procedures in their systems also. Holding fast to MANRS activity fortifies this position.
Making the Internet a safer place than it is today is a goal shared by many participants of the industry. We at LU-CIX try to help wherever we can, and certainly would like to add our own homework to the goal. Therefore we think that MANRS is a very worthwhile initiative that brings together in one set of guidance rules many of the industry best practices, and also allows us to publicly show our support for a safer Internet.
CIO, LU-CIX Management G.I.E.Coordination 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.GoCache has always been committed to implementing best practices and we strongly believe we can build a secure network if everyone contributes to this same goal. By joining the MANRS community, we reassure this commitment and encourage others to do the same.
Network Engineer, GoCacheThe reliability and security of the internet is a big concern for us! Belgium is only a small country, having a trustworthy connection to other national and international operators should be of key strategic importance for everyone. We hope with doing our small part that we can help the internet forward.
FounderIt is in everyone's best interest to keep the internet clean. By doing our part and conforming to the objectives stated by MANRS, we can reduce the impact of intended and unintended misconfigurations and the risk of abuse of internet resources and we hope that others will do so as well.
BIT BVColoClue 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!
We agree with the underlying principles of the MANRS initiative and in practice we have always ensured our network complies with the requirements it outlines. A number of recent high-profile cases have reaffirmed the need for such processes and we look forward to the wider adoption of these practices.
Technical Director, Custodian DC Ltd.DC1 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.
RENU joins MANRS to improve its security posture on the internet by acting upon and deploying MANRS actions that can improve the security of the global routing table. For a long time, multiple routing incidents such as route hijacks, route leaks and IP address spoofing have occurred on the internet causing network outages and cost implications to many companies. RENU also wants to ease collaboration with other network operators thus encouraging stability and reliability on the internet.
