Enterprise software demands enterprise-grade security

Security and regulatory compliance are not afterthoughts bolted onto finished applications — they are embedded into our specification-first methodology from the first conversation.

Our security principles

Three foundational commitments that underpin every Xamun engagement.

Specification-First Security

Every project begins with a security and compliance review during the DesignStudio specification phase. Before any code is written, the specification captures:

• Authentication and authorisation requirements
• Data classification and handling rules
• Regulatory compliance requirements
• Integration security (API auth, encryption in transit)
• Infrastructure and hosting security

Full Source Code Ownership

You own your source code from Day 1. This means:

✓ Your security team can audit every line of code
✓ You control hosting and security configuration
✓ No vendor lock-in or third-party dependency
✓ Implement your own security tooling and monitoring

Cloud-Native Architecture

Applications built using micro-monolith cloud-native architecture designed for:

✓ Your choice of cloud (AWS, Azure, GCP) or on-premises
✓ Container-based isolation between components
✓ Horizontal scaling without architectural changes
✓ Standard security group and network policy config

Regulatory compliance expertise

Built-in compliance for the standards your industry demands.

Healthcare — HIPAA / NHS

✓ PHI encryption at rest and in transit
✓ Role-based access with minimum necessary access
✓ Audit logging for all PHI access and modifications
✓ Business Associate Agreement (BAA) support
✓ NHS Digital standards compliance

Data Protection — GDPR

✓ Privacy by design and by default
✓ Data minimisation and purpose limitation
✓ Right to erasure and data portability
✓ Consent management and DSAR workflows
✓ Cross-border data transfer compliance (SCCs)

Financial — PCI-DSS

✓ PCI-DSS compliant payment processing
✓ Full audit trails for financial transactions
✓ Data Processing Agreement (DPA) support
✓ Secrets management — no hardcoded credentials
✓ Breach notification workflow support

Development security practices

Security is built into the development lifecycle, not checked at the end.

Secure Code Generation

✓ AI-generated code reviewed by experienced developers
✓ SQL injection, XSS, CSRF caught during generation
✓ Dependency scanning for known vulnerabilities
✓ No hardcoded credentials, API keys, or tokens

Quality Assurance & CI/CD

✓ SonarQube quality gates on every build
✓ Automated test coverage (unit, integration, E2E)
✓ Manual code review for security-sensitive components
✓ CI/CD pipeline security with environment separation

Data handling

How your data is protected during development and after delivery.

During Development

• Encryption at rest and in transit for all data
• Synthetic or anonymised data for development and testing
• Restricted and logged access to production environments
• All team members under non-disclosure agreements
• Data classification applied from specification phase

After Delivery

• Full source code and deployment configs transferred to you
• You control all production data and infrastructure
• Xamun does not retain production data after completion
• Complete audit trail for all data access
• Ongoing xDD engagements include data handling terms

Infrastructure security

Your application, your infrastructure, your control.

Client-Owned Deployment

Deploy to your choice of cloud provider (AWS, Azure, GCP) or on-premises. You choose and configure the hosting environment.

No Vendor Access

For turnkey projects, all Xamun access is revoked upon delivery. Active xDD engagements have logged, restricted access only when you grant it.

Container Isolation

Container-based isolation between application components. Infrastructure-as-Code for reproducible, auditable deployments. Automated backups and DR configuration.
