Automatically Discover API Sensitive Data Flows

We are excited to announce a significant new addition to Upwind’s API Security capability – the automatic discovery and classification of sensitive data flows.

Upwind automatically tracks sensitive data routes and classifies sensitive data as PCI, PII, and PHI by analyzing API samples recognized by the Upwind sensor, making it easy to identify where you are at elevated risk.

Examples of sensitive data that Upwind identifies include:

  • PHI data: patient information, medical records & insurance information
  • PII data: SSNs, IDs and emails
  • PCI data: credit cards and billing information

How Upwind Identifies Sensitive Data Flows

In order to identify sensitive data flows, Upwind searches for patterns at the packet level and then masks any data found, ensuring it remains secure and is never sent outside of your environment. When an API request for sensitive data  is detected, Upwind labels it with a sensitive data tag and classifies it by its type and category, such as PCI for a MasterCard number. We are continuing to extend this capability, and customers will soon be able to create their own custom regular expression (regex) to classify sensitive data.

Use Upwind’s automated sensitive data flow tracking to easily understand API data security risks, prioritize remediation efforts for APIs with sensitive data flows, and ensure a proactive approach to data security.

Introducing the Upwind Identity Graph: End-to-End Identity Security

Identity used to be treated as a directory problem: find the user, inspect the groups, review the assigned roles, and decide whether the account has too much access. That model no longer matches the cloud. A single person may authenticate through Okta, inherit permissions from multiple groups, receive role assignments in more than one cloud,…
