Testimonials
Tier4 Services adapted a clearly defined mission: to uphold the tough standards of high-speed communication via the Internet every minute of the day and provide secure communications. MANRS is a great initiative to help to improve the standards on a global scale and make the Internet more secure.
Connecticut Education Network originated as a research & education network and now functions as a Tier 2 ISP for multiple industry verticals. Responsible safeguards on the signaling plane ensure we're not contributing to the spoofing/hijacking problem, and membership in MANRS reflect our commitment to making the Internet a better place for our members and their constituents.
Since its beginnings, RedIRIS has striven to maintain a secure and resilient network, deploying the most updated best practices and, as a National R&E Network, disseminating them to its customers in order to get from them a commitment of deploying these best practices in their networks as well. Adhering to MANRS initiative reinforces this position.
We strongly support MANRS precisely because its aims are converging with those we have been pursuing for years. This means that no change to our policies was necessary with our joining MANRS. We are glad that MANRS has come to light and we will do our best to support MANRS and its goals.
CEO FASTNETDC1 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.
It 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 BVAdherence to MANRS is an important commitment that operators make back to the Internet community. Together we aim to remove the havens from which miscreants maintain the freedom and anonymity to attack our network and our customers.
Claranet GroupWe, at NIX.CZ, believe internet security is very important. For this reason we do our best to secure internet exchange in Prague with best in class security policies. Our aim is to deliver stable, reliable and secure platform for data exchange.
CTO, NIX.CZ, z.s.p.o.We 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, CERNETProviding good connections for people requires hard work and, above all, responsibility. MANRS is a vital initiative for the smooth running of the WWW, and it's an honor to be a part of it.
The 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.
FounderThe MANRS IXP Initiative brings together in one place, in an easy to access form, all of the relevant information on routing security best practice for our members. We incorporate the MANRS material into our training courses and guidance, to provide our members with a consistent approach to routing security and BGP policy best practice.
