Mimecast, a provider of cloud-based email management for Microsoft Exchange and Office 365, has revamped its email security tool, which the company says will enable end user autonomy while allowing IT department full visibility of the organisation’s email security.

Mimecast Email Security allows the IT department to activate features and permissions for specific individuals or groups, who can manage their own security settings on a per-message basis.

The new security tool features attachment and blocked sender management in compliance with enterprise security requirements.

Mimecast email security gives users the flexibility to remain in Microsoft Outlook while reporting spam or managing their blocked sender lists, in addition to access to message actions from within Microsoft Outlook.

The message actions include user defined message encryption, intuitive document clean-up or conversion options to remove unwanted or hidden metadata, user activated ‘strip and link’ functionality, and email stationery and branding selection.

The new security platform allows system administrators to activate functions for individual employees or subsets of users as required, and control over all default settings.

Using the new tool, a client side installation can be effected through existing software management systems and it offers users with greater control over their own email, through functions such as user self-service for quarantine management and the recovery of lost or deleted items.

Mimecast Unified Email Management product director Grant Hodgkinson said by building granular controls and permissions into Mimecast Email Security and adding functionality, the company wants to help IT departments find a balance between productivity, flexibility and control.

"This technology is designed to allow IT teams to retain visibility and control where it is needed, while giving individual users greater power over their own email in a way that makes both sides more productive," Hodgkinson added.

Mimecast customer Knight Frank IT Services & Support Chris Balmbro said the new security tool is bringing additional security features to the end-user and we see this having huge potential for IT departments.

"With ever more importance being attached to data security, it will be great for our end users to be able to choose to encrypt their emails ad hoc or even to send mail as a Closed Circuit Message," Balmbro added.

"We also believe that allowing employees to check their own spam queues and release messages should they wish will mean fewer calls to our Service Desk team, helping to increase productivity both for our IT department and our end users."
