Security Architecture Practices: Thoughts on Security by Design Current and Future state

Late security fixes run tens of times more expensive than early ones, and the pressure is intensifying as AI-enabled systems, which don't hold still after deployment, get acquired and rolled out faster than governance can keep pace.

Security by design remains vendor-side, software-centric, siloed across disconnected approval gates, compliance-driven, and largely a point-in-time exercise rather than something sustained across information systems’ operational lifecycle.

To extend security-by-design into a demand-side, establish is as an enterprise-wide practice, embedded in design, acquisition, procurement, and third-party risk decisions, paired with continuous security  assurance instead of a one-time gate. Finally, aim for standardization as a compounding advantage

Invest earlier, mandate continuous assurance in procurement, establish clear ownership, and treat security as a design decision not an afterthought.
