How to build effective protection against all 13 threat types

Traditional email gateways are still a critical part of your security infrastructure. But to protect against all 13 email threat types, you also need a newer type of solution: API-based inbox defense.

Unlike gateway solutions that use signature-matching and payload analysis to prevent threats from arriving to your inbox, API-based inbox defense solutions use historical communication data to spot anomalous emails that evade the gateway and land in users’ inboxes. Malicious emails are removed instantaneously.

Think beyond the gateway to protect against all 13 threat types.

To protect your organization from socially engineered attacks, you need an additional layer of defense beyond your gateway solution: API-based inbox defense.

Inbox defense relies on APIs to integrate directly with your users’ inboxes. This integration provides visibility into both historical and internal email communication for every individual in the organization. Communication data is used to train artificial intelligence (AI) to create a statistical model or an identity graph for each user that reflects their communication patterns.

Using historical data the model will define users’ regular email addresses, individuals they communicate with, the type of requests they make, and many other behaviors. When something abnormal happens that is outside of an individual’s identity graph, AI instantly flags it as malicious and removes it from the user’s inbox.
