Cybersecurity Service Updates: Beef Up Your Microsoft 365 Email Security with Mimecast

Microsoft Office 365 is arguably the industry standard when it comes to enterprise-level essential business software. However, we feel that it does not provide adequate cybersecurity measures to protect critical data. Organizations should augment it with best-in-class solutions that efficiently manage email disaster recovery and data security while simplifying retention and compliance.

This is where Mimecast comes in. A fully integrated, cloud-based subscription service, Mimecast mitigates the risks of moving email infrastructure to the cloud. It complements Outlook’s email management capabilities by addressing security, continuity, and archiving requirements, on top of migration and operational challenges.

An all-in-one solution highly recommended by cybersecurity service experts in Nashville, Mimecast reduces the risk, cost, and complexity of managing business email by doing away with the need to manage different solutions from multiple vendors. For organizations that have made Office 365 their primary email software, Mimecast mitigates single vendor exposure with a broad set of tools designed for Outlook email management.

Email security

Mimecast tools add another layer of security to Outlook by preventing malware, spam, and other threats from reaching the network. Mimecast Targeted Threat Protection scans all emails and blocks malicious URLs, weaponized attachments, and social engineering techniques frequently used in phishing and other targeted attacks. Mimecast Secure Messaging enables users to send out emails securely even when TLS encryption is not an option. Employees also can use Mimecast to safely send out emails with large file attachments that would normally exceed the limits of their Outlook mailbox.

Email archiving

Depending on the subscription type, Outlook emails deleted by the user will be permanently deleted within 90 to 180 days if not correctly labeled for an archive.

Mimecast’s email archiving system provides an independent and verifiable copy of data stored in perpetuity. It provides a highly scalable and resilient archive in the cloud that lets users search and find email fast and provides administrators with powerful tools to manage mailboxes, e-discovery, litigation support, and Office 365 compliance archiving.

Email continuity

While Outlook guarantees a 99.9 percent uptime throughout a year, it still allows 43 minutes of outage a month, or nearly nine hours of downtime a year.

With Mimecast Mailbox Continuity users can continue sending and receiving emails even in the event of a disaster, planned downtime, or an Office 365 outage. You can be sure your email works 100 percent of the time.

Link protection

Outlook relies on a reputation-based URL list. For example, Office 365 will check a link against a reputation rating – but if it is a new malicious link, the program may still permit access. Low-volume phishing, spear phishing, and ransomware campaigns can easily evade this.

Mimecast, on the other hand, uses multi-factor analysis of all links and attachments and converts these into safe file formats prior to delivery. Mimecast also has a data loss prevention feature that blocks unauthorized sends of protected data. Mimecast Sync & Recover guards against human error, technical failure, or malicious attacks.
