Secure SDLC
security review embedded in architecture, build, and release - not a post-launch afterthought.
Last updated: February 16, 2026. Our security program covers both application delivery and AI-specific risk - model and vendor review, prompt/data handling, and human oversight - aligned to NIST AI RMF and EU AI Act principles.
Definition
Security built into delivery means security reviews and controls are part of the same architecture, build, and release cycle every feature goes through - not a separate audit that happens after the product is already built. Concretely, that's a secure software development lifecycle (SDLC), least-privilege access control with audit logging, and monitoring/incident response for systems already in production.
security review embedded in architecture, build, and release - not a post-launch afterthought.
least-privilege permissions, MFA-ready tooling, and audit logging on sensitive actions.
observability, alerting, and incident runbooks for systems already live.
AI Governance
AI systems introduce risks a traditional SDLC doesn't cover on its own - what data reaches a model, what actions an agent can take unsupervised, and whether a vendor's model handling meets your compliance bar. We treat these as first-class controls, not an afterthought bolted onto existing security practice.
Due diligence on model providers, data retention terms, and fine-tuning/training exposure before any model touches client data.
Input/output filtering, scoped tool access, and redaction of sensitive fields before they reach a model's context window.
Irreversible or high-risk agent actions - payments, external messages, production changes - route through human review by default.
Delivery structured around NIST AI RMF's Govern, Map, Measure, Manage functions, with EU AI Act-style risk classification per workflow.
