Secure development lifecycle
Threat modeling for critical flows, peer review on every change, static and dependency analysis in the pipeline.
Services
We modernize outdated apps, add AI to them and build new ones, with every service around the app under one roof. Each can be commissioned on its own.

Trust & security
Regulated healthcare, enterprise security teams and payment providers hold us to a high bar. Here is how we protect your code, data and access, and how we build and test apps that stand up to audits and attackers.

How we protect your work
These practices apply whether we are building your product, embedded in your team or testing an app someone else built.
Threat modeling for critical flows, peer review on every change, static and dependency analysis in the pipeline.
Client environments, credentials and data accessed only by the people assigned to the work, with SSO and MFA.
Encryption in transit and at rest, no production data in development without written approval, and secure disposal at project end.
Security testing by engineers separate from the build team, against OWASP MASVS and MASTG.
We work under your MSA, data processing agreement and, for healthcare, a business associate agreement.
Documented incident response with defined notification timelines agreed in contract.
Compliance frameworks
We design, build and verify apps against these frameworks and prepare the evidence your auditors need. Certification of your organization remains with your auditors and assessors.
| Standard | Where it applies | What we do |
|---|---|---|
| HIPAA | Healthcare apps handling protected health information | Architecture, safeguards, audit logging and readiness evidence |
| SOC 2 Type II | Enterprise and workforce platforms | Control-aligned access, change management and audit preparation |
| GDPR | Apps with users in the EU and UK | Consent, data minimization, residency and erasure workflows |
| PCI-DSS | Apps that take payments | Tokenized payments that keep card data out of scope |
| OWASP MASVS | Every app we build or test | Security requirements, assessments and penetration testing |
| WCAG 2.2 | Every app we design | Accessible design and conformance audits |
| DICOM | Medical imaging | Image viewing, measurement and markup |
