A senior security & AI delivery bench — assembled for your environment.
Lyfye is led by Richard Chang, a CISSP-certified security architect. We deliver through specialist pods across security architecture, GRC, AppSec, cloud, and agentic AI — formed to match your risk profile, compliance needs, and timeline.
Proof-first deliverables: diagrams, controls, runbooks, and evidence packs.
Security-built AI systems: guardrails, evals, and governance — not demos.
Pod-based delivery: senior specialists, assembled per engagement.
Limited capacity by design. Currently accepting two new engagements this quarter.
Pod composition varies by engagement. Leadership oversight and delivery accountability are provided by Rich.
Designed for teams that can't afford ambiguity.
Bench size reflects partner network capacity and delivery coverage assembled per scope. We do not claim certifications we do not hold.
Security Architecture & Zero Trust
Reduce attack surface and tighten identity, network, and cloud controls with pragmatic architecture that security teams can run.
- •Identity & access design (SSO, MFA, conditional access)
- •Network segmentation and trust boundaries
- •Cloud security posture alignment
- •Threat modeling for critical systems
Governance, Risk & Compliance
Operationalize controls and evidence collection for audit readiness without slowing the business.
- •SOC 2 / ISO 27001 / HIPAA-aligned control mapping
- •Policy + procedure systems that teams actually follow
- •Evidence plans, audit trails, and readiness assessments
- •Executive risk register and remediation roadmap
Secure AI Systems & Agentic Workflows
Build agent-enabled workflows with guardrails: data boundaries, safety checks, evaluation, and human oversight.
- •Agent architecture + tool permissions
- •Prompt/response governance and logging
- •Evaluation harnesses and regression tests
- •Security reviews for AI features and integrations
Apps & Websites with Embedded Agents
Ship secure, production-grade experiences — websites, internal copilots, customer intake, and automation — with agents built in from day one.
- •AI intake forms → structured outputs
- •Knowledge-backed support assistants
- •Sales/ops automation workflows
- •Deployment-ready builds with security controls
Every engagement includes delivery governance: scope control, peer review, and versioned artifacts.

You don't hire a person. You get a pod — a set of senior roles assembled to deliver outcomes with accountability.
Principal Security Architect (Engagement Lead)
Architecture decisions, risk tradeoffs, executive alignment.
IAM & SSO Specialist
Identity controls, conditional access, MFA strategy.
Cloud Security Engineer
Cloud posture, encryption, network boundaries, logging.
GRC & Audit Readiness Lead
Control mapping, evidence plans, audit documentation.
Application Security Lead
Threat modeling, secure SDLC, CI/CD controls.
Detection & Response Advisor
Telemetry strategy, alerting, incident playbooks.
AI Systems Engineer
Agent workflows, tool permissions, evaluation harness.
Delivery Ops (QA + Documentation)
Peer review, artifact packaging, handoff readiness.
Roles are staffed from Lyfye's specialist bench and partner network based on scope, timeline, and required coverage.
How engagements run
Align
Clarify scope, define success metrics, and identify highest-risk systems. You get a written plan before work begins.
Outputs:
- →Engagement plan + scope boundaries
- →Risk assumptions + data handling plan
- →Artifact list + delivery milestones
Design & Build
Execute in weekly delivery cycles with peer review. Every change is tied to a control, risk, or measurable outcome.
Outputs:
- →Architecture diagrams + control mapping
- →Secure implementation tasks + acceptance criteria
- →Evidence artifacts and remediation backlog
Prove & Handoff
Package deliverables for executives and auditors. Your team gets artifacts that are usable, not theoretical.
Outputs:
- →Executive readout + risk register
- →Runbooks, policies, and evidence pack
- →Handoff workshop + next-quarter roadmap
Artifacts you can forward internally
Security Architecture Pack
Diagrams, trust boundaries, identity and network decisions.
Threat Model & Abuse Cases
Systematic risk discovery with mitigations mapped to controls.
Audit Readiness Evidence Pack
Control mapping, evidence checklist, and collection workflow.
Secure AI Guardrails
Data boundaries, tool permissions, safety checks, evaluation.
Executive Risk Register
Prioritized risks with owners, timelines, and remediation plan.
Operational Runbooks
Incident playbooks, access reviews, and change procedures.
Everything is versioned and packaged for handoff — built for collaboration and audit scrutiny.
Real engagements. Real outcomes.
These case studies represent actual client engagements. Details have been anonymized to protect confidentiality.

Passed SOC 2 Type II audit on first attempt
Fintech (Growth-Stage): Zero-Trust Architecture Implementation
Rapid growth outpaced security controls, regulatory pressure mounting
Identity-first architecture, least-privilege access, continuous verification
Achieved compliance readiness with measurable attack surface reduction
B2B SaaS (Enterprise): Agentic AI with Security Guardrails
Needed AI automation without exposing sensitive customer data
Secure agent blueprint, data boundaries, permission scoping, audit logging
Deployed production agents with comprehensive safety controls

Leadership
Accountability starts with leadership
Richard Chang
Principal Security Architect + AI Systems Builder
Rich leads Lyfye's security and AI delivery practice. He specializes in architecting defensible security controls, designing audit-ready governance systems, and building production-grade AI applications with embedded guardrails.
His approach is built around pragmatic execution: every recommendation must be implementable, every control must be auditable, and every deliverable must be usable by the team that inherits it.
"Security isn't theoretical. If a control can't be implemented and defended under scrutiny, it's not a control — it's a wishlist item."
Frequently Asked Questions
