In the digital age, email impersonation and phishing attacks have become increasingly common, making it crucial for organizations to adopt robust security measures. Mimecast, a leading email security provider, offers a range of impersonation protection strategies to help businesses safeguard their communication channels. In this blog, we explore 14 key strategies provided by Mimecast to mitigate the risks of impersonation.

1. DMARC Implementation

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a crucial protocol for preventing email spoofing. Mimecast supports DMARC implementation, ensuring that only authorized senders can use your domain for email communication.

2. SPF and DKIM Alignment

Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) are email authentication techniques. Mimecast helps align these protocols, verifying the legitimacy of the sender and the integrity of the message content.

3. Advanced Threat Protection

Mimecast's Advanced Threat Protection identifies and blocks sophisticated threats, including impersonation attempts, using a combination of sandboxing, URL protection, and attachment scanning.

4. Impersonation Protect Policies

Mimecast allows administrators to set up impersonation protect policies. These policies can detect and block emails that appear to come from internal domains or specific external domains, reducing the risk of spoofing.

5. User Education and Awareness

Mimecast promotes user education through simulated phishing attacks and training materials. By educating employees on how to spot impersonation attempts, organizations can build a stronger defense against these threats.

6. Secure Messaging Gateway

Mimecast's Secure Messaging Gateway provides a layer of protection against inbound and outbound threats, including impersonation emails. It filters suspicious messages before they reach user inboxes.

7. Email Continuity Service

In case of an email outage or attack, Mimecast's Email Continuity Service ensures uninterrupted email access. This service mitigates the risk of attackers exploiting such vulnerabilities to impersonate legitimate services.

8. Large File Send

Mimecast's Large File Send feature allows secure sharing of large files without clogging up email servers. This reduces the risk of impersonators using large file attachments as a vector for attack.

9. Multi-Factor Authentication

Enhancing account security with multi-factor authentication is a key strategy offered by Mimecast. This additional layer of security makes it harder for attackers to impersonate users or gain unauthorized access.

10. Data Leak Prevention

Mimecast's Data Leak Prevention capabilities help identify and prevent sensitive information from being sent outside the organization, reducing the risk of data breaches that could be exploited for impersonation purposes.

11. Archiving and Compliance

Mimecast provides archiving and compliance solutions that ensure all email communication is securely stored and can be easily retrieved for audit purposes. This helps in investigating and proving the authenticity of emails in case of impersonation disputes.

12. URL Protect

URL Protect is a Mimecast feature that scans and rewrites URLs within emails, protecting users from malicious links that could lead to impersonation scams or malware downloads.

13. Attachment Protect

Attachment Protect sandboxes suspicious attachments, preventing malware from executing and protecting users from impersonation attempts that rely on malicious attachments.

14. Comprehensive Reporting and Dashboards

Mimecast offers comprehensive reporting and dashboards that provide visibility into email traffic patterns, threats detected, and policy effectiveness. This helps administrators identify and respond to impersonation attempts promptly.

By implementing these 14 impersonation protection strategies with Mimecast, organizations can significantly reduce the risk of falling victim to email impersonation and phishing attacks. Mimecast's suite of solutions offers a holistic approach to securing email communication, ensuring businesses can operate safely in today's digital landscape.
