Custom Single Sign-On System (SSO / IAM)

One login for all your services. Full control over users, access, and personal data. Lifetime warranty on results.

When This Is Needed

Clients register in each of your services from scratch — and get lost between them

Accesses, consents, and personal data are scattered across different systems

Ready-made solutions do not cover your tasks: working with legal entities, powers of attorney, offer signing, integration with government services

We build a unified authorization platform exactly for your processes. You get a working system, not a box that needs to be finished.

What Modules You Get

The platform is assembled from modules. You determine the delivery set: any module can be added, removed, or modified for the task — including features and integrations not on the list.

Single Sign-On (SSO / OAuth 2.0 / OIDC)

User gets into any ecosystem service in one click. Login by username, SMS, government services, banking ID, social networks. Two-factor authentication, session and device management, rights separation.

Individual Profiles

Unified personal data storage. Full name, documents, addresses, contacts, bank accounts. Automatic and manual verification. API for external services.

Legal Entities (Legal ID)

Organization, employee, and authority management. Structure and roles, power of attorney system, personal data protection, member invitations.

Offers and Consents

Offer publication and versioning. Access to functionality only after accepting the current offer. Personal data processing consents, version history, real-time notifications.

Notifications

Email, SMS, calls, push, and real-time notifications. Message templates, API for managing mailings and subscriptions.

Administrative Panel

Control over the entire system from one point: users and sessions, partner applications, permissions and certificates, suspicious activity monitoring, action log with report export.

Directories

Single source of reference data: document types, countries, currencies, banks. Updated once — applied everywhere. Versioning and change audit.

Why Us

Platform Already in Production

We developed the "Kvorum ID" service for VTB Registrar: legal entity hierarchy, power of attorney system, integration with government services. The platform serves thousands of users and dozens of connected services.

Code and Infrastructure Are Yours

Full access to source code and documentation. No hidden licenses or vendor lock-in.

Full Cycle

We do not sell a box — we build a solution: from audit and design to launch and knowledge transfer to your team.

Quick Launch

We provide ready Docker images, Kubernetes manifests, and Helm charts — deployment takes days, not weeks.

Frequently Asked Questions

Timelines depend on module composition and integrations. Basic Minimum configuration launches in 2.5–3.5 months, full Enterprise system — in 8–11 months. Exact timelines are fixed in the contract after audit.

Yes, this is one of the key advantages. The platform operates on OAuth 2.0 and OpenID Connect standards — connecting new services happens through the admin panel without changing their code.

If after project delivery an error or non-compliance with the technical specification is discovered — we will fix it for free, no matter how much time has passed. The warranty covers all code written by us.

Yes. The offers and consents module is mandatory for regulated industries (finance, telecom, healthcare). We design architecture considering 152-FZ and industry standards requirements.

At the launch stage, we train your team, transfer technical and user documentation, API specifications, and deployment instructions.

Yes, the platform is modular. You can launch MVP with basic SSO and profiles, then sequentially connect legal entities, offers, notifications, and other modules without rewriting the core.
