Cloud Email and ESGs

With some 80% of organisations expected to be on a Cloud based email service by 2021 protection from a third party vendor is critical.

Microsoft O365 inclusions and options

Microsoft Office 365 includes Exchange Online Protection (EOP) with all O365 plans. EOP includes both an anti-spam and signature-based anti-malware service.

Microsoft offers Advanced Threat Protection (ATP) to address advanced attachment and URL-based threats, DLP and email encryption (enabling an organization to monitor, encrypt or block messages based on policy) in some enterprise packages and as stand-alone offerings.

With Microsoft being a generalist technology provider (albeit a very good one!) and not being a specialist security vendor, the protection provided by these offerings may not be sufficient for all organisations.

Our recommendation…

Although the Cloud based email Services offer a level of protection, often these are basic levels of protection compared to the functionality and flexibility provided by a dedicated solution. Secure-ISS recommends that organisations consider supplementing their O365 or other cloud email services with a dedicated ESG solution.
