Service endpoint · not scored

1-255619-1569808606-388.rt.yammer.com is part of yammer.com's infrastructure

This is a backend address used by yammer.com, not a website you'd visit. It rejects browser requests with an HTTP 400 error, yammer.com is an established domain (Tranco rank #2515), and none of our security checks flagged it. We don't score service endpoints: the yammer.com report covers the company behind it.

Got here from a link?

Apps and websites talk to addresses like this in the background, so there's nothing to see in a browser. If a link to it asks you to sign in, pay or download something, don't: go to yammer.com directly instead.
