Security

Security Is a Foundation,
Not a Feature

With over 40 years of combined experience in software development and security, we build systems assuming they will be attacked. Every layer hardened. Every action auditable.

Principles

Security Pillars

Every system we build adheres to these foundational security principles. No exceptions. No shortcuts.

Zero Trust

Every request is verified. Every action is authenticated. No implicit trust between components.

  • All inter-service communication authenticated
  • Token-based access with short lifetimes
  • Continuous verification, not one-time auth

Defense-in-Depth

Multiple layers of security controls. If one fails, others contain the breach.

  • Network segmentation and firewalls
  • Application-level access controls
  • Data encryption at rest and in transit

Least Privilege

Components only have access to what they need. Nothing more.

  • Role-based access control (RBAC)
  • Scoped API keys and tokens
  • Regular access reviews and pruning

Secure by Design

Security is architectural, not cosmetic. Built in from the first line of code.

  • Threat modeling before development
  • Security review at every milestone
  • Automated security scanning in CI/CD

Agent Security

Secure Agent Design

Autonomous systems require additional security considerations. Every agent we build includes these security controls.

Permission Scopes

Every agent operates within explicitly defined boundaries. No ambient authority.

Model Isolation

AI models run in sandboxed environments. No direct access to production data or systems.

Data Handling

Sensitive data is classified, encrypted, and access-controlled. PII handling follows strict protocols.

Audit Logs

Every action recorded. Every decision traceable. Complete forensic capability.

Fail-Safe Behavior

When things go wrong, agents fail safely. Graceful degradation, not catastrophic failure.

Rate Limiting

Configurable limits prevent runaway behavior. Automatic throttling under anomalous conditions.

Practices

Ongoing Security

Security isn't a one-time event. We maintain continuous security practices throughout the development lifecycle and beyond.

  • Regular penetration testing
  • Dependency vulnerability scanning
  • Security-focused code reviews
  • Incident response planning
  • Employee security training
  • Vendor security assessments
“We build systems assuming they will be attacked. Every input is validated. Every action is logged. Every component is hardened.”
