Pulse Analysis

Internet routing security has moved from a niche concern to a core business requirement as companies increasingly depend on seamless, global connectivity. The Mutually Agreed Norms for Routing Security (MANRS) framework offers a set of operational best practices—filtering bogus announcements, preventing IP address leaks, and maintaining accurate routing tables. While large carriers in Western Europe have embraced these standards, many Central and Eastern European ISPs remain outside the program, creating blind spots for enterprises that cannot verify the integrity of their upstream paths.

In the Balkans and neighboring regions, the absence of MANRS participants is stark. Croatia and Slovenia, despite having technically competent providers, show no entries in the official MANRS registry, and Austria’s country code returns a generic “No Data” response. This lack of transparency hampers procurement decisions and forces businesses to rely on trust rather than measurable compliance. The current MANRS participant directory offers limited search functionality, making it difficult for buyers to identify compliant providers at the country level.

The newly released MANRS white paper positions enterprise buyers as the missing catalyst for change. By integrating routing security criteria into vendor assessments, procurement teams can incentivize ISPs to adopt MANRS practices, effectively turning market demand into a compliance driver. Companies should incorporate routing‑security clauses into contracts, request regular compliance reports, and collaborate with industry groups to raise awareness. As more enterprises prioritize this hidden dependency, the pressure on ISPs to attain MANRS certification is likely to increase, fostering a more resilient Internet ecosystem.
