Benefits of Using the Global Bypass List

Utilizing the Global Bypass List offers several advantages:

• Enhanced Communication: Critical emails from trusted sources can reach your inbox without delay.
• Reduced False Positives: Legitimate emails are less likely to be caught in spam filters, minimizing disruption.
• Improved Workflow: Teams can operate more efficiently without the interruption of blocked emails.

Challenges of the Global Bypass List

While the Global Bypass List is beneficial, it also comes with challenges:

• Potential for Abuse: If too many addresses are added, it can lead to security vulnerabilities. Malicious actors might exploit the bypass status.
• Management Overhead: Regularly reviewing and maintaining the list requires time and attention.
• False Sense of Security: Relying too heavily on the bypass list can lead to complacency regarding overall email security practices.

Best Practices for Managing the Global Bypass List

To maximize the effectiveness of the Global Bypass List while minimizing risks, consider the following best practices:

• Limit Entries: Only add essential contacts to the bypass list. This reduces the risk of security breaches.
• Regular Audits: Periodically review the list to ensure that only necessary entries are maintained.
• User Training: Educate your team about the importance of email security, encouraging them to report suspicious emails even from trusted sources.
• Monitor Email Traffic: Keep an eye on email traffic patterns for signs of unusual activity.

Practical Tips for Effective Use

1. Identify Critical Contacts: Determine which senders are essential for business operations and prioritize adding them to the bypass list.
2. Use Domain Bypass Wisely: If your organization frequently communicates with an entire domain (like a partner company), consider adding the domain rather than individual email addresses.
3. Implement Layered Security: Use the bypass list as one tool in a comprehensive email security strategy, including other Mimecast features like spam filtering and phishing protection.

Cost Considerations

While there are no direct costs associated with using the Global Bypass List itself, consider the following:

• Time Investment: Regularly managing the list requires time, which can translate to labor costs.
• Security Risks: Any lapses in email security due to mismanagement of the bypass list could lead to data breaches, which can be costly in terms of fines and recovery efforts.

Conclusion

The Mimecast Global Bypass List is a valuable feature for organizations looking to streamline their email communications while maintaining security. By understanding how to configure and manage the list effectively, you can enhance your organization’s email workflow while mitigating potential risks. Remember to regularly review and audit the list to ensure it remains effective and secure.
