Telepresence was initially developed by Ambassador Labs, which creates open-source development tools for Kubernetes such as Ambassador and Forge. We welcome all contributions from the community. You can help us by submitting an issue, pull request or reporting a bug. Join our active Slack group to ask questions or inquire about paid support plans. Telepresence is currently under active development. Register to receive updates and announcements. You can quickly debug locally without waiting for a container to be built/push/deployed. Ability to use their favorite local tools such as debugger, IDE, etc. Ability to run large-scale programs that aren't possible locally.

Authress offers a comprehensive Authentication API tailored for B2B needs. While authentication may seem straightforward at first glance, the intricacies of authorization can quickly escalate, making it unwise to navigate this complexity alone. Achieving robust authorization is a time-consuming endeavor; an average software team might spend around 840 hours developing authorization logic for basic scenarios, and this effort can multiply as additional features are integrated into the application. Lacking the necessary expertise exposes your organization to significant security vulnerabilities, potentially leading to breaches of user data, non-compliance with regulatory standards, and substantial financial repercussions. * Secure authorization API—Rather than constructing your own authorization framework, leverage our API for seamless integration. * Granular permissions—Establish various access levels and categorize them according to user roles, allowing for as much detail as needed. * Identity Provider integrations—Effortlessly connect your chosen identity providers through a straightforward API call. * SSO and comprehensive user management—Enjoy streamlined single sign-on capabilities along with complete control over user administration, ensuring a secure and efficient user experience.

Resurface is a runtime API security tool. Resurface continuous API scanning allows you to detect and respond in real time to API threats and risks. Resurface is a purpose-built tool for API data. It captures all request and response payloads, including GraphQL, to instantly see potential threats and failures. Receive alerts about data breaches for zero-day detection. Resurface is mapped to OWASP Top10 and alerts on threats with complete security patterns. Resurface is self-hosted and all data is first-party.
