Security ArchitectureBuild Once, Defend Forever
Whether you're building new or modernizing legacy systems, you get security architecture aligned with Zero Trust principles that balances protection with the efficiency your team needs to move fast.
Security Architecture Principles
Modern security architecture isn't about adding more tools—it's about designing systems where security is inherent.
Zero Trust Architecture
Move beyond perimeter security to a model where trust is never assumed and always verified.
- Verify explicitly with every access request
- Use least privilege access controls
- Assume breach and minimize blast radius
Cloud-Native Security
Security designed for dynamic, distributed environments across AWS, Azure, and GCP.
- Infrastructure as code security
- Container and Kubernetes hardening
- Cloud security posture management
Defense in Depth
Layered security controls that provide redundancy and resilience against sophisticated attacks.
- Multiple independent security layers
- Overlapping controls at each layer
- Graceful degradation under attack
What We Avoid
Architecture Deliverables
Comprehensive security architecture spanning identity, network, cloud, and application layers.
Zero Trust Design
Architecture blueprints implementing never-trust, always-verify principles across all access.
Cloud Security Architecture
Secure-by-design patterns for AWS, Azure, and GCP with multi-cloud considerations.
Identity Architecture
IAM strategy including SSO, MFA, privileged access, and service account governance.
Network Segmentation
Micro-segmentation design that limits lateral movement and contains breaches.
DevSecOps Integration
Security controls embedded in CI/CD pipelines for shift-left security.
Security Stack Design
Tool selection and integration architecture that eliminates gaps and redundancy.
Security Monitoring Design
Logging, detection, and response architecture for comprehensive visibility.
Architecture Documentation
Security reference architectures and standards your team can maintain and evolve.
Architecture Questions
Common questions about security architecture engagements.
Legacy systems require a pragmatic approach. I focus on wrapping legacy apps in modern security controls—API gateways, network segmentation, enhanced monitoring—rather than trying to rebuild them. We create a roadmap for gradual modernization while immediately reducing risk.
I've designed security architectures across AWS, Azure, and GCP, including multi-cloud environments. This includes landing zone designs, identity federation, network architecture, and cloud-native security tooling. I also help organizations migrate from on-premises while maintaining or improving their security posture.
A focused architecture review and recommendations typically takes 4-6 weeks. A comprehensive redesign with implementation guidance takes 2-4 months. I can also provide ongoing architecture advisory as part of a fractional CISO engagement.
I provide detailed architecture documentation and implementation guidance, and I can work alongside your team during implementation. However, I don't do hands-on engineering myself—my value is in the design and strategic direction. I'm happy to recommend implementation partners if needed.
This is critical. Security that's too restrictive gets bypassed. I design friction-appropriate controls—stronger security for sensitive actions, streamlined access for routine work. User experience is a key design constraint, not an afterthought.
