What is KnowBe4 Cloud Email Security (Formerly Egress)
KnowBe4 Cloud Email Security (formerly Egress) is a cloud-based email security platform focused on reducing inbound and outbound email risk for organizations using services such as Microsoft 365 and Google Workspace. It provides capabilities such as phishing and malware detection, outbound data loss prevention controls, and policy-based email encryption for sensitive messages. The product is typically used by IT and security teams to protect users from email-borne threats and to prevent accidental or unauthorized data sharing via email. It differentiates by combining inbound threat protection with outbound content inspection and encryption workflows in a single email-focused service.
Inbound and outbound coverage
The product addresses both inbound threats (such as phishing and malicious content) and outbound risk (such as misdirected emails and sensitive data exposure). This reduces the need to stitch together separate tools for gateway protection, DLP, and encryption for email-specific use cases. For organizations where email is a primary data egress channel, this consolidated approach can simplify policy management and incident handling.
Email encryption and secure delivery
It supports encrypting sensitive emails and controlling how recipients access protected content. This is useful for regulated communications and for sending confidential information to external parties without requiring them to be part of the same tenant. Encryption features also help standardize secure-send workflows for end users, reducing reliance on manual processes.
Policy-based content controls
The platform applies rules to detect sensitive content and enforce actions such as blocking, warning, or encrypting messages. These controls help prevent common user errors like sending data to the wrong recipient or sharing restricted data types. For teams that need practical DLP focused on email rather than broad endpoint coverage, the policy model aligns with day-to-day email governance needs.
Email-centric DLP scope
Its DLP capabilities are primarily oriented around email content and email-related workflows. Organizations seeking broad data security coverage across endpoints, SaaS apps, file stores, and databases may need additional tools. This can limit its suitability as a single enterprise-wide data security platform.
Tuning and false positives
Like many content inspection and anti-phishing systems, effectiveness depends on configuration, policy tuning, and ongoing maintenance. Overly strict rules can generate user friction and administrative overhead, while permissive rules can miss risky messages. Security teams should plan for an initial tuning period and periodic review of detections and exceptions.
Integration and deployment constraints
Deployment approach and feature availability can vary depending on the organization’s email environment and chosen integration method. Some advanced controls may require specific configurations, permissions, or mail-flow changes that need coordination with messaging administrators. This can increase implementation effort in complex or highly customized email setups.
