Over the past 12-18 months, Microsoft has been investing in external security/privacy certifications to prove the overall compliance for their cloud services. Notably, Office 365 is now ISO 27001, HIPPA, FISMA and the European Union’s privacy laws.
Microsoft has now just announced that Yammer is also now ISO 27001 certified. Given Yammer’s important relationship with Office 365, it is a key requirement for Yammer to support the same certifications as Office 365 as business users transparently move documents, content and information from SharePoint to Yammer and back again.
