    All Mimecast staff and contractors are subject to an Acceptable Use Policy, Business Code of Conduct and Ethics, and general Security and Compliance awareness training, which includes acceptable use of corporate assets. Mimecast implements a variety of technical solutions to monitor compliance to these areas. In addition to this, employees are instructed and trained to report information security concerns to the Mimecast Security team. Suspected compliance issues are emailed directly to the Corporate Compliance Officer or discovered and addressed through internal audit activities.

    As a part of the automated on-boarding & de-registration process, information asset owner or delegates are informed of any new starter or job change and are required to change access rights according to the job function's profile. This may involve removal or editing access rights, as well as the addition of new access rights. Mimecast reviews standard user access rights during internal audits and this is also audited by Mimecast's external ISO-27001 auditors. This is done at least annually, often bi-annually. Asset owners must review the privileged account holders on a quarterly cycle. The effectiveness of the review process is monitored during internal audit investigations.

    Mimecast uses a Role Based Access Control model with a "least privileged" approach with all user accounts associated to a unique individual identifier. All new access requests follow access control processes. Existing privileged access rights are reviewed for appropriateness and changes to access rights are fully auditable within system logs. In the event of an invalid login, there is no distinction between user ID or password, and neither are identified in failed notification.

    Virtual Private Network (VPN) connections into Mimecast are secured via two-factor authentication involving a pin and a physical or soft token. Remote access attempts, connection time, disconnection time, and location are logged. Multiple failures generate an alert to the Security Team.
