Exchange Online Protection (EOP), a cloud-based email filtering service that helps protect organizations against spam and malware, is an option for both Microsoft Office 365 and Exchange 2013. EOP replaced Microsoft’s Forefront security program, although the basic code has barely changed from the Forefront security offered with Exchange 2010. With EOP, Microsoft added email policy management and enabled the product to work bi-directionally, meaning EOP also provides a level of data loss prevention for Exchange 2013 and Office 365 users.
EOP is considered a baseline level of protection. It includes only basic features and focuses on the Connection Management layers, which can typically catch about 95% of spam emails. It doesn’t focus on content examination, which means spear phishing attempts are not caught. For companies wanting more rigorous security, Microsoft offers an optional security service called Exchange Online Advanced Threat Protection (ATP), which adds content analysis, including the ability to which routes messages and attachments without a known virus/malware signature to a special hypervisor environment where it uses machine learning and behavior analysis to detect any malicious intent.
Why companies look to enhance Office 365 security
With built-in EOP limitations, and the potential overkill of optional ATP features for many organizations, companies are looking at thirdparty solutions. In addition to being more cost-effective than Microsoft’s optional security services, many companies are wary of having to rebuild their ‘allow and block’ lists. These lists of trusted and blocked senders have been constructed over time, and since no easy import facility exists, “false positives” can plague IT organizations and require considerable time to rectify. Finally, adding third party security incorporates yet another layer of email security management, which is important in a world where online threats are always increasing.
