Introducing Email Security

Coro's Email Security module simplifies email protection, offering a comprehensive solution from pre- to post-delivery, including encryption services.

Coro guards against a wide range of threats, such as identity spoofing, malware and ransomware injection, malicious embedded links, generic and spear phishing, and email account takeover. Coro can also identify content categorized as spam in email message bodies, headers, and attachments.

When activated, Coro provides real-time email threat detection by working with your connected Gmail or Microsoft 365 cloud service through an API connection. This API-based approach means Coro can seamlesssly interact with your email provider directly without requiring admin users to perform specific configuration for each user. Coro acts on mail activity notifications sent by Google or Microsoft and performs remediation actions as necessary:

API-based email protection

When Coro detects a threat in your protected users' emails, Coro raises an Email Security ticket and remediates the email according to a combination of the settings you specify in your workspace and the severity of the threat. Tickets specify the type of threat encountered, and can either require admin users to intervene and perform actions, or just disclose how Coro automatically remediated it.

To view the full list of Coro's Email Security ticket types and the corresponding outcomes, see Email Security ticket types.

note

Coro's API-based email protection is available for Gmail and Microsoft 365 only. To add protection for other third-party email providers, or to learn how you can add additional protection for all email services, see Coro's Inbound Gateway email proxy.

How Coro works with existing email providers

Coro's email security module works alongside your Google or Microsoft email service.

Coro performs detection and remediation after Gmail or Microsoft 365. All pre-existing email rules within either service are processed before Coro starts scanning emails for phishing or malware, and if Gmail or Microsoft 365 quarantines an email, this takes priority over Coro.

However, for customers using the Inbound Gateway add-on, Coro instead performs detection and remediation ahead of both providers, in that all preexisting email rules within Gmail or Microsoft 365 are processed after Coro has scanned and remediated emails for phishing and malware.
