SAML 2.0, OIDC, OAuth 2.0, LDAP/AD, social logins — handled from one place, and proven at the 10M-member scale of EBS in Korea. Security, performance, and login experience, owned together.
SSO isn't only a security problem. Handling bursts of concurrent logins without latency, and giving users a login flow that doesn't friction up — those have to come together.
We've been building SSO systems across diverse environments and standards for around 15 years. The performance and operational know-how validated at EBS, where 10M+ members log in, all sit inside ElasticLogin.
And we don't stop at delivering the product — we provide direct engineering support for SSO integrations, even when the surrounding stack isn't ours.
Single Sign-On is a domain where security alone isn't enough — performance optimization and Login Experience matter just as much. Our product carries the best of both.

The pieces that usually scatter — multi-protocol, directory integration, federation, social login, every device — gathered into one server.
Performance proven at EBS, where 10M+ members log in. Bursty, concurrent login traffic comes through without latency.
SAML 2.0, OpenID Connect (OIDC), and OAuth 2.0 — followed faithfully, so integrating with standard-based systems stays clean.
Integrates with existing directories like OpenLDAP and Microsoft Active Directory. You don't have to migrate user data — use it where it already lives.
Federate with external IdPs over OpenID Connect and SAML 2.0. Multiple organizations, multiple member pools — managed from one place via trust relationships.
Google, Facebook, Naver, GitHub, and the rest. Let users sign in the way they already do everywhere else.
Web applications, mobile apps, desktop applications — single sign-on works the same across every client form factor.
Problem
EBS has 10M+ members and needed to unify authentication across a family of sites with very different sizes, languages, platforms, and user contexts.
Our Solution
We delivered a high-availability SSO built on ElasticLogin, alongside member-data consolidation and a clean, stable SDK. The result holds up reliably at 10M+ scale.
Problem
Teacher member data was split between Visang's Vivasaem and T-school services and had to be unified — with two-way sync against a Teacher Authentication module and a single sign-on flow. The two systems used different member-data attributes, and the integration had to cover desktop, mobile web, and mobile apps consistently.
Our Solution
Built on ElasticLogin, we wired up two-way member-data sync between the services and connected the whole thing to the Teacher Authentication module. Different attribute schemas were reconciled with structured mapping rules, and the same single sign-on experience flows across desktop, mobile web, and mobile apps.
