SOWL – Verifiable Credentials for IAM & KYC | esatus AG

WALLETS CHANGE HOW INFORMATION IS USED.

Properties are verified once, stored as a credential, and reused. Systems are not designed for this today. SOWL ensures that credentials become usable in existing processes.

Two worlds that don't fit together.

Today, identity works within systems. Accounts are created, roles assigned, and entitlements managed. Every application makes its own decisions. As soon as these need to be used across systems, overhead is created. Information is transferred, verified again, and reconciled manually.

Wallets introduce a new model. Properties are made available as credentials and verified on demand. This model works across system boundaries. Credentials can be used directly in different processes. Existing systems are not designed for this. SOWL brings both worlds together.

SOWL brings credentials into your systems.

SOWL connects existing IAM, KYC, and business systems with wallets. Business decisions stay where they are made. SOWL turns them into credentials that can be shared. At the same time, credentials from wallets are verified and used within your systems. This is how SOWL connects both directions. Generating and using credentials in one consistent structure.

More about the technical integration of SOWL.

How credentials are created and take effect.

1. Trusted data exists, for example in IAM or KYC.

2. It is issued as a credential and made available in the wallet.

3. A system requests the credential and verifies it automatically.

4. The result feeds directly into existing decisions.

This creates a cycle of issuance and use. Without duplicate verifications and without duplicate data storage.

What SOWL does in the process.

Credentials become reusable

Once created, they can be used across multiple systems.

Processes become seamless

Media breaks and duplicate verifications are eliminated.

Verification is automated

Credentials are verified by the system instead of being reconciled manually.

Control is maintained

Validity and revocation are automatically taken into account with every use.

How SOWL is used.

Wherever credentials should no longer be verified manually. For example, in the KYC context around EUDI and PID. Verifications are converted into credentials and reused.

Or in existing systems, verified credentials feed into access decisions. SOWL ensures that both levels work together. Without replacing existing systems.

The benefits of SOWL.

Integration without rebuilding

Credentials are integrated into existing systems without any architectural changes.

No central storage

Credentials stay with the user and are only used when needed.

Standards instead of a siloed solution

Integration is carried out via established interfaces and remains interoperable.

Designed for EUDI

Regulatory requirements are integrated directly into processes.

SOWL is in live production.

CIAM migration with eIDAS 2.0

A European financial institution is introducing Bare.ID as its central identity provider — across four stages, embedded in a regulated security architecture, prepared for the EUDI Wallet from the start.

Verifiable corporate identity

Who is acting is known. Whether they are authorized to act has rarely been clear. esatus developed the vLEI Authenticator together with GLEIF — corporate identity and authorization to act become cryptographically verifiable, integrated into Keycloak.

Compliance Digitized

More than 1,000 paper documents, up to ten minutes of verification time per person. With inGo, esatus solved the credential problem for the Lindner Group — under five seconds, fully logged, GDPR-compliant.

Base access on credentials

In the Siemens showcase, esatus explored how access decisions can be based on verified credentials from a wallet — without replacing or rebuilding existing IAM systems.
