Oathkeeper vs BeyondTrust: What are the differences?

Developers describe Oathkeeper as "A cloud native Identity & Access Proxy". A cloud native Identity & Access Proxy (IAP) which authenticates and authorizes incoming HTTP requests. Inspired by the BeyondCorp / Zero Trust white paper. Written in Go. On the other hand, BeyondTrust is detailed as "Privileged access management solutions". It supports a family of privileged identity management, privileged remote access, and vulnerability management products for UNIX, Linux, Windows and Mac OS operating systems.

Oathkeeper and BeyondTrust can be primarily classified as "Cloud Access Management" tools.

Some of the features offered by Oathkeeper are:

• Identify the user and provide the user session to API backends
• Restrict access to certain resources based on a set of rules
• Transform access credentials (e.g. OAuth2 Access Tokens, SAML Assertions, ...) to a format (e.g. JSON Web Token, Plaintext, Basic Authorization, ...) consumable by your API services

On the other hand, BeyondTrust provides the following key features:

• Universal Privilege Management
• More Than Just Passwords
• Frictionless experience for users
