Discover the cutting-edge benefits our clients enjoy from the global Toptal network.

Challenge: The company needed to understand and implement effective Okta-based access control management but lacked the expertise.
Solution: Toptal first set up a test environment to enable development and testing without disrupting existing systems. Then the team utilized the open-source LightSAML library for PHP to build a flexible SAML 2.0 integration, allowing the platform to authenticate with Okta or any other SAML-compliant identity provider.
Outcome: Users gained streamlined and secure access across applications using their Okta accounts, resulting in a significantly improved login experience. The integration provided a scalable and compliant access control foundation to support the company’s future needs.
