Shipping code without security built in from the start is the most expensive mistake in software development, and it is the most common one. By the time vulnerabilities surface in production, remediation costs are higher, timelines are compressed, and customer trust is already damaged.
Tracy R. Reed, Director of Cybersecurity Practice at Unrisk, Cybersecurity Maturity Model Certification (CMMC) Lead Assessor, Certified Information Systems Security Professional (CISSP), International Organization for Standardization (ISO) 27001 Lead Auditor, and instructor at the University of California San Diego Extension, has spent more than 25 years helping organizations from early-stage companies to federal contractors solve exactly this problem. “If your security team only shows up at the end of a sprint, it’s already too late,” Reed states.
Shift Left, But Start With Culture
Shifting security left means introducing it early in the development process rather than treating it as a final gate before release. The technical argument for this is well established. The cultural argument is less often made and more important to get right. Tools and policies introduced without developer buy-in get worked around. Security checks that feel like obstacles to delivery become the obstacles teams learn to minimize.
The organizations that successfully embed security into their development lifecycle change both the process and the mindset. Developers who understand secure coding principles, threat modeling, and common vulnerabilities, such as those in the Open Worldwide Application Security Project (OWASP) Top 10, make better decisions at every stage of the build. They catch problems before a separate security team ever sees the code. When security becomes part of how developers think rather than a function that reviews their work afterward, risk decreases, and delivery speed increases simultaneously.
Automate Security Into the Pipeline
Static code analysis, container scanning, and dependency checks belong inside the CI/CD pipeline (continuous integration and continuous delivery or deployment), running consistently on every build. Reviewing them periodically after an application reaches production is too late and too slow. Automation is what makes security scalable; it removes dependence on manual review cycles that slow teams down and introduces consistent, repeatable enforcement that manual processes cannot sustain at volume.
Automated security checks catch vulnerabilities when they are cheapest to fix rather than when they are most expensive to remediate. At Unrisk, the implementation approach is built around controls that enhance resilience without disrupting the pace at which engineering teams need to move. Security built into the pipeline does not block velocity. It protects it.
Build Threat Modeling Into Architecture
The decisions that most significantly shape a product’s security posture are made in the design phase, before a line of code is written. Waiting until code review to think about security means responding to decisions that were already made without it. Threat modeling at the architecture stage, using frameworks like spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege (STRIDE) to understand attacker motivations and the MITRE Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK) framework to align defenses, forces teams to anticipate how the system will be targeted. Good architecture makes secure defaults the path of least resistance for developers and builds defense-in-depth into the foundation rather than layering it on afterward.
Revisiting threat models as the architecture evolves keeps security current rather than locked to an early-stage assessment that no longer reflects the product. Security is a continuous, integrated discipline, and the organizations that treat it that way build products that hold up under pressure and earn the kind of customer trust that, once lost, is extraordinarily difficult to recover.
