Why Choose IRONSCALES over Mimecast




Adapting to an Evolving Email Security Landscape
Email security has changed a lot in the last 20 years. Basic protocols like authentication and signature-based secure email gateways (SEGs) used to be enough—but they can't keep up with the new tactics attackers use.
Now email security needs to address "malicious intent" like social engineering, and actively protect at the mailbox level. Solutions now use AI, machine learning, and automation, as well as human insights, to fight advanced threats like business email compromise, account takeover, and VIP impersonation.

How are IRONSCALES and Mimecast Different?
IRONSCALES and Mimecast use very different methods to securing an organization’s email environment.
- Deployment and Integration Differences:
❌ Mimecast primarily utilizes a Secure Email Gateway (SEG) that requires MX record changes, positioning itself between your email provider and users. This setup can be complex and may necessitate significant changes to your email infrastructure.
✔ IRONSCALES uses an API-based solution that seamlessly integrates with cloud email providers like Microsoft 365 and Google Workspace. This approach allows for rapid deployment without altering MX records, minimizing disruption and ensuring a smoother implementation process.
- Threat Detection & Response:
❌ Mimecast employs traditional threat detection methods, focusing on predefined rules, signatures, and static analysis to identify threats. While effective against established known threats, this approach may face challenges in identifying novel, sophisticated attacks.
✔ IRONSCALES uses Adaptive AI and crowdsourced threat intelligence to detect and remediate threats in real time, providing full visibility into attack campaigns, indicators of compromise, and emerging phishing tactics.
- Threat Intelligence Approaches:
❌ Mimecast maintains a proprietary threat intelligence database, updating defenses based on internal research and analyses.
✔ IRONSCALES utilizes a crowdsourced threat intelligence model, drawing insights from a global community of over 25,000 security professionals. This collective intelligence accelerates the identification of zero-day threats and enhances the platform's adaptive learning capabilities.
- Bottom line: Mimecast's traditional security approaches react to known threats, while IRONSCALES' Adaptive AI proactively evolves to stop emerging attacks before they spread.
