Office 365

Making Office 365 safer for business

The Challenge

With over 85M corporate users and a rate of adoption exceeding 50,000 organizations each month, Office 365 appears to be the email platform of the future.

But the risks to email remain whether delivered 100% from the cloud or in a hybrid environment. Security threats such as ransomware, impersonation and spear-phishing remain a primary concern in protecting the email attack vector. Humans remain the weakest link in an organization’s defenses. IT admins must have a plan B in the event of a mail disruption, as it’s unacceptable to have productivity crippling email downtime. And administrators need an independent archive that guarantees data immutability and chain of custody to respond quickly to litigation and e-discovery requests.

Mimecast Solution

Mimecast makes cloud email safer by addressing three critical email needs: security, archiving and continuity. Integrated service bundles are designed for and delivered 100% in the cloud, with no network infrastructure for staff to manage.

Mimecast solves cloud infrastructure challenges with:


Targeted Threat Protection for Office 365

Relying solely on Office 365 for AV/AS protection and protection from advanced threats such as spear-phishing is risky.

Get better protection with a layered security approach by adding Mimecast S1 to work independently or in tandem with security offerings such as EOP, to tackle the risk from whaling, spear-phishing and other advanced threats.
