Auth0 takes a modern approach to Identity, providing secure access to any application, for any user. Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is part of Okta, The World’s Identity Company™. Auth0 lets you quickly integrate authentication and authorization for web, mobile, and legacy applications, with new Fine Grained Authorization (FGA) that goes beyond role-based access control. Authenticate users across all applications with a customized, secure, and standards-based single login. Universal Login connects users to a central authorization server. Credentials aren’t transferred across sources, which boosts security and protects against phishing and credential stuffing attacks. OAuth 2.0 recommends that only external user agents (like the browser) be used by native applications for authentication flows. Auth0’s Universal Login achieves this while enabling SSO.

Thinfinity Workspace is a virtual desktop (VDI) and virtual application (VDA) platform that runs natively on Oracle Cloud Infrastructure (OCI), with no third-party hypervisor layer. It publishes Windows and Linux desktops and applications, internal web apps and files to any HTML5 browser or to native Windows, iOS and Android clients, with no VPN. The browser needs no install; the native clients add low-level USB device redirection. How it works: a gateway, a broker and a lightweight agent on each session host. Agents connect outbound to the gateway over port 443, so session hosts need no inbound firewall rules for user access. Sign-in works with Active Directory, LDAP, SAML 2.0, OAuth 2.0 or RADIUS, with built-in multi-factor authentication and role-based permissions. Session recording and audit logging, with SIEM export, support HIPAA, GDPR and PCI DSS reviews. Linux, Java and web applications can also run as per-session containers on Kubernetes (OKE), and a REST API supports automation. Standard VDI features include multi-monitor, printing, clipboard and file transfer, USB redirection, session sharing, load balancing and high availability. Also deploys on AWS, Azure, Google Cloud, IONOS, VMware, Hyper-V, Proxmox, hybrid and air-gapped networks. Licensed per concurrent user.
