Security as a build-time decision, not a final review
Cybersecurity, in engineering terms, is the practice of designing systems that resist unauthorized access, data exposure, and abuse access control, encryption, authenticated and rate-limited APIs, and hardened dependencies applied as architectural decisions rather than a checklist run before launch.
A security review done after a system is built finds problems that are expensive to fix an access control model baked into the data layer, or a service that was never designed to authenticate its callers. Security decided at build time is cheaper, more thorough, and doesn't get traded away under deadline pressure the way a pre-launch checklist item does.
Least-privilege access control, encryption at rest and in transit, rate-limited authenticated APIs, audit logging, and dependency hardening are baked into how we build from day one the exact practices detailed in our security case study on systems handling sensitive data.
