We approach security from inside the code. Most serious weaknesses in enterprise applications are design and implementation problems: an authorization check in the wrong layer, a token accepted without validating its audience, a secret in a configuration file, a library nobody has upgraded in years. We find them, fix them and make them harder to reintroduce.
We are an engineering company, not a certified penetration-testing organization. We work alongside your security team, auditors and testers: they assess, we help you resolve.
Vulnerability and dependency remediation
A scanner report with hundreds of CVEs is not a plan. We triage findings by real exploitability in your context, fix what matters first, and document why the rest is mitigated or not applicable. Fixes are upgrades, patches or configuration changes, each covered by regression tests. Then we put dependency scanning and a software bill of materials into your pipeline so the list does not grow back.
Authentication and authorization
We design and implement authentication with Spring Security, OAuth 2.0 and OpenID Connect, integrated with identity providers such as Keycloak, Microsoft Entra ID or Okta. We pay attention to the details that cause incidents: token validation, audience and expiry checks, session handling, service-to-service authentication. Authorization is modelled on your actual roles and data, with RBAC or ABAC, enforced in the service layer and tested, including tenant isolation where several clients share one system.
API security and secrets
Input validation, protection against mass assignment, rate limiting and error messages that do not leak internals. Secrets move out of code and configuration into a vault or key management service, with rotation that does not require a release.
Cryptography and key management
We integrate established cryptographic libraries and services; we do not invent algorithms. The difficult part is usually the key lifecycle: generation, storage in an HSM or KMS, rotation, revocation and destruction, and envelope encryption for data at rest. We design these processes so that they work in operations, not only on paper.
Secure financial and payment systems
Financial software has its own failure modes. We engineer banking and payment integrations, including ISO 20022-based financial messaging, with idempotent payment workflows that cannot execute twice, reconciliation that detects discrepancies early, signing and approval steps with four-eyes controls, and cryptographic services for custody and digital-asset platforms. Every state change leaves an audit trail that explains who did what, when, and on what basis.
Audit trails and a secure supply chain
Logging that is useful for investigations without exposing secrets or personal data, tamper-evident audit records, reproducible builds, pinned dependencies and CI pipelines with least privilege. These measures produce the technical evidence that compliance work relies on. Implementing OAuth or encryption does not by itself make a system compliant: the assessment remains with your compliance function and auditors, and we support them with facts.
