Product Overview: Mimecast Secure Email Gateway
The Mimecast Secure Email Gateway is a comprehensive, cloud-based solution designed to protect organizations from a wide range of email-based threats, ensuring the security and integrity of their email communications.
What it Does
Mimecast Secure Email Gateway acts as a robust firewall for email, providing pre-delivery protection by blocking email-based threats before they reach the organization’s mail server, whether it is on-premise, in the cloud (such as Microsoft 365 or Google Workspace), or in a hybrid environment. This gateway reroutes both inbound and outbound emails through its proxy, where they are thoroughly scanned for various types of threats.
Key Features and Functionality
Advanced Threat Protection
- The gateway utilizes sophisticated, multi-layered detection engines and advanced threat intelligence to protect against malware, spam, phishing, and targeted attacks, including spear-phishing and email impersonation.
URL and Attachment Protection
- Every URL in inbound emails is re-written to point to Mimecast’s threat intelligence cloud, preventing users from accessing malicious sites. Email attachments are pre-emptively scanned in a secure sandbox or converted to threat-less file formats to protect against weaponized attachments and macro threats.
Dynamic User Awareness and Training
- The system includes Dynamic User Awareness, which redirects users to a customizable security training page if they click on suspicious links. This feature educates users on identifying and avoiding phishing attempts and other email-based threats.
Data Leak Prevention (DLP)
- Outbound emails are granularly inspected for malicious URLs and attachments, going beyond traditional DLP scanning to prevent data leakage and ensure compliance with organizational policies.
Centralized Policy Management
- The gateway offers a centralized administrative interface, allowing administrators to set and enforce global and finely-tuned security policies easily across the organization. This ensures consistent application of security controls and compliance with regulatory requirements.
Email Continuity and Archiving
- Mimecast Secure Email Gateway guarantees 100% email continuity, ensuring that email services remain available even during outages. It also provides email archiving functionality for legal compliance and data management.
Integration and Visibility
- The solution integrates seamlessly with other security tools, such as Microsoft Sentinel, through data connectors that enable easy log collection and provide pre-created dashboards for insights into email-based threats. This integration aids in incident correlation and reduces investigation response times.
AI-Powered Detection
- Mimecast leverages advanced AI and machine learning technologies, tuned over 20 years based on trillions of emails and millions of users, to deliver industry-leading protection against emerging threats.
In summary, the Mimecast Secure Email Gateway is a powerful tool that enhances an organization’s security posture by providing comprehensive protection against email-based threats, ensuring data security, and maintaining email continuity. Its advanced features and centralized management make it an essential component for any organization seeking robust email security.
