Custom authorization server development
We design and build authorization servers on top of an open core, following the OAuth 2.0 and OpenID Connect specifications. Compliant with IETF standards and modern security best practices.
Authorization servers — from architecture to production
Single sign-on, user, session and role-based models
A service for working with the authorization server: code exchange, client sessions, granular logout.
Your developers won't have to deal with it. We'll pick and configure the right gateway.
Admin API and UI to manage OAuth entities such as clients and scopes
We build integrations with your OTP, Selfie and other providers, or help you choose them.
Docker, CI/CD, monitoring, health checks. Deployment consulting for your own infrastructure.
We comply with the RFCs — OAuth 2.0, OpenID Connect, PKCE, Token Introspection and more.
We follow modern security standards for encryption, hashing and secret storage.
We consult and build the product around your requirements, constraints and specifics.
Metrics, logs, masking, liveness/readiness probes, graceful shutdown, Docker images — all included.
We plan ahead to minimize the cost of future migrations.
We provide everything needed to work with the authorization server. Your developers won't have to think about it.
A solution designed around your business — not a business bent to fit someone else’s product
Off-the-shelf solutions drag along hundreds of features you'll never use. We design a modular architecture around your needs — nothing extra, minimal resource footprint.
Your server, in your infrastructure. No vendor lock-in, no surprise pricing changes. User data stays with you.
Keycloak upgrades often break customizations. With us, the code is written for you — updates and maintenance included, no surprises during migrations.
No need to bend your business logic to another product's limitations. We embed authorization into your architecture, not the other way around.
Open Core
At the heart of our solutions is Versola — a core we built for constructing OAuth 2 and OpenID Connect servers on Scala 3.

Founder
6 years at Tinkoff — from engineer to head of backend development for Tinkoff ID. Over that time the service grew from tens of thousands to 50 million users. That experience became the foundation of Versola.
