Office 365 Email Security in the Enterprise: 2019 Benchmarking Survey


40% of enterprises reported that Office 365 login credentials were compromised during the prior year, and over a quarter of those said it happened 10 or more times.  — Michael Osterman, Principal Analyst, Osterman Research

How are enterprises securing their Office 365 email—and are they being successful?

This report gives IT and security professionals, from CISOs to SOC analysts to email admins, the opportunity to benchmark their own Office 365 email security posture and planning with answers from their peers. During June 2019, Osterman Research interviewed IT and security decision-makers at over 300 large enterprises in the US and UK on how they have approached deploying and securing Office 365 for their corporate email.

The survey report gives data and insights on practical issues including security performance, types of additional security deployed, time spent remediating email-related breaches, how users report suspicious emails, security budget growth this past year, how they’ve organized their SOCs, and what SIEMs they use. Key situational data are also covered, like how the migration to Office 365 was managed, and the size of their IT and security staff, with reference staffing and malicious email remediation cost calculations included by Osterman Research in the report.
