MICROSOFT ENTRA & IDENTITY SECURITY
Secure sign-in for people. Controlled access for applications. We connect Microsoft Entra ID, FIDO2 and PKI to protected APIs, Azure Functions and Key Vault – from access design to automation that works in daily operations.
THE OPERATING CONTEXT
An application needs API access, a Function needs to automate a workflow or sign-in needs to become phishing-resistant. Meanwhile, permissions, secrets and certificates spread across systems. We examine the complete access path: who signs in, which application acts, which permissions it needs and how keys are protected. We turn that understanding into suitable Entra configurations and integrations. FIDO2 protects sign-in; workload identities, API validation and PKI protect technical connections. Rollout, failure scenarios and operational handover are part of the delivery.
Tested access and automation, with clear permissions and defined operating procedures.
A CONTROLLABLE RESULT
Delivery follows your concrete task. Four outcomes connect identity, integration and operations – from a FIDO2 pilot to a custom Function with protected API access.
Deploy passkeys and FIDO2 security keys with PIN or biometrics in Microsoft Entra ID. Align Conditional Access policies and authentication strengths; plan registration, lost keys and separate emergency access from the start.
Design app registrations, service principals and managed identities around the workflow. Separate user and application permissions, limit scopes and roles, and review access. Use managed identities or workload identity federation where the platform and target system support them.
Integrate OAuth 2.0 for access and OpenID Connect for sign-in. APIs validate tokens and required permissions. Develop Functions, scripts and interfaces for your workflows with error handling, controlled retries, logging and traceable tests.
Manage keys, secrets and certificates in Azure Key Vault with targeted access rights. Align renewal, rotation and monitoring with the application. Integrate certificate-based authentication and trust chains where appropriate; define owners and operating procedures.
THE APPROACH
Start with a single API, a FIDO2 pilot or an existing automation. Scope follows your needs. Before rollout, we test permitted and denied access, failures and the intended recovery procedures.
Inventory users, applications, APIs, Functions and target systems. Review sign-in methods, permissions, secrets and certificates. Result: a clear access map with concrete risks, dependencies and priorities.
Assess user and workload identities separately. Define roles, API permissions, Conditional Access and suitable authentication strengths. Check technical prerequisites and required licenses. Result: an access design and measurable acceptance criteria.
Test passkeys or security keys with representative users. Check registration, device and application compatibility, lost keys and controlled emergency access. Result: a practical rollout plan with support for your users.
Connect app registrations and workload identities; validate tokens and permissions. Develop Functions, scripts or interfaces. Prefer supported access without long-lived stored secrets; connect necessary secrets and certificates to Key Vault and PKI. Result: a representative integration.
Test allowed and denied access, invalid tokens, expired certificates, rotation and outages. Retries must avoid duplicate actions; logs must not expose secrets. Result: test records, known limitations and a rollout plan with fallback.
Introduce changes in stages, verify access and assign ownership. Document configuration, automation and operating procedures; hand over monitoring, alerts and recovery. Result: an integration your team can understand and operate.
Plan access reviews, offboarding, secret and certificate rotation, and changes to APIs and policies. Remove permissions that are no longer needed. Result: an agreed maintenance plan with owners and repeatable checks.
THE RIGHT FIT
For IT owners, security teams and developers improving sign-in and application access or securely automating an individual workflow.
You want stronger protection against phishing at sign-in. We connect suitable methods to application checks, a pilot, registration and practical recovery procedures.
A business system, application or automation needs API access. We establish user or application access, token validation, permissions and appropriate handling of certificates and secrets.
An individual workflow needs automation, such as processing API data and triggering a follow-up action. We develop the appropriate Function or interface and test identity, permissions, failure scenarios and operations together.
Credentials are stored in configurations, ownership is unclear or rotation causes outages. We connect vaults, PKI and applications to controlled rotation, traceable permissions and monitoring.
THE NEXT CONTROLLED STEP
Whether you need FIDO2, an API integration, Key Vault or a custom Function, tell us about your task. Together we define dependencies, a suitable scope and a first verifiable result. You do not need a finished design to start.
