Description of yammer.com
yammer.com appears to be the web entry point for Yammer, an enterprise social networking and workplace collaboration service associated with Microsoft. The supplied categories classify it as business networking, collaboration, and social networking, which aligns with Yammer’s role as an internal communication platform for organizations and teams.
The scanned page shows a Microsoft-branded sign-in screen rather than a public marketing homepage, suggesting the domain is currently directing users to an account login flow for workplace access. The domain is long-established and uses Microsoft-operated infrastructure, which is consistent with a major enterprise service.
Safety Assessment for yammer.com
Scan results were broadly favorable at the time of this scan. No detections were reported by 0 out of 91 security engines, and the checked threat databases and blacklist sources did not report the domain as malicious or phishing-related. The domain is also very old, has a strong traffic rank, and the observed page content matches a plausible Microsoft sign-in experience for a business collaboration platform.
One automated malware scan produced a generic "suspicious" result on the /index page, but no malware family was named, no external links or referenced domains were flagged, and this signal was not corroborated by the broader engine consensus or blacklist checks. In this context, that isolated heuristic appears to be a low-confidence caution rather than strong evidence of harmful activity.
Based on available data, no threats were detected at the time of this scan.
Technical Description
The domain uses a valid SSL/TLS certificate issued to Microsoft Corporation, with expiry shown as 2026-11-29. Hosting also appears to be on Microsoft infrastructure, and the nameserver set includes both Akamai and Azure DNS, which is consistent with large-scale enterprise delivery and traffic distribution. The observed resources load from an official Microsoft content delivery domain.
DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from DNSSEC validation. No DNS-based blocklist hits were reported in the provided data, and no notable server-side security issues were evident from the scan snapshot.
