Testimonials
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.
Adherence 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.

MANRS represents the future of Internet routing security. Network operators in the MANRS community are pioneers, making global routing infrastructure as robust and secure as possible, through innovation and investment. As a leading global communications and network service provider, China Telecom (Americas) has been collaborating with the MANRS team since early 2019 to implement the best routing security standards on all of our major Internet networks. Today, we are excited to be count ourselves as a MANRS participant, and hopefully inspire more large-scale network operators to join our ranks.
Vice President, China Telecom Americas CorporationIn 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.
URAN Association community is participating in MANRS because routing security is a growing area of concern for network operators around the globe. Whether from accidental misconfiguration or malicious hijack, the results are often more than just inconvenient. Joining MANRS and the Internet2 community’s efforts connect us with a community of security-minded professionals and organizations committed to making the global routing infrastructure more robust and secure.
We believe it is our responsibility as a network operator to deliver a secure and robust Internet service to our customers, and to assure our peers that the trust that the Internet is built on is delivered through these MANRS initiatives. For us it is a mark of quality.
