Documentation Introduction


Avanan is an API-based inline protection service that protects your SaaS applications from advanced threats, such as:

  • Zero-Day Threat
  • Phishing
  • Account Takeover
  • Data Leakage
  • SaaS Shadow IT Discovery

How It Works

Email Protection

When an email is sent, Avanan intercepts and analyzes it before the email is delivered to the recipient. If the verdict is malicious, then the email is handled according to the configured workflow (for example, quarantine). Otherwise, the email is delivered to the recipient.

Avanan also inspects internal and outgoing traffic, both for data leakage and for phishing and malware. Emails can be removed and modified post-delivery if needed.

Supported Applications

  • Microsoft Exchange Online (Office 365 Mail)
  • Gmail

File Sharing Applications

When you upload a file to the application, Avanan inspects it for malware and against the organization's DLP policy. Files with detected threats are quarantined or vaulted.

Supported Applications

  • Microsoft OneDrive
  • Microsoft SharePoint
  • Google Drive
  • Citrix ShareFile
  • DropBox
  • Box

Messaging Applications

Avanan inspects every message for malware, DLP, and phishing indicators. It also inspects every uploaded file for malware and DLP.

Supported Applications

  • Microsoft Teams
  • Slack

BEC/Compromised Accounts (Account Takeover)

Avanan inspects the behavior of users inside the Microsoft environment – their login patterns, correspondence patterns, and many more – to determine if an account has been compromised before any damage is done. The account is then automatically blocked by the system, or manually blocked by an administrator.
