Key Skills

What to Include on a Security Architect Resume

• A concise summary that states your security architect experience level, strongest domain, and the business problems you solve.
• A skills section that mirrors the job description language for Zero Trust Architecture, Threat Modeling (STRIDE/PASTA), Cloud Security Architecture, Identity Architecture.
• Experience bullets that connect security architect, zero trust, security architecture to measurable outcomes such as cost savings, faster delivery, better quality, or improved customer results.
• Tools, platforms, certifications, and methods that are current for cybersecurity roles.
• Recent projects that show ownership, cross-functional work, and a clear result instead of generic responsibilities.

Sample Experience Bullets

• Designed the zero-trust architecture for a 10,000-person enterprise, defining identity verification, device trust, and micro-segmentation standards across all network zones. The architecture reduced lateral movement risk by 90% and was a key factor in achieving FedRAMP authorization
• Created the security reference architecture that 50+ application teams follow for authentication flows, data encryption patterns, logging standards, and API security controls. Published it as an internal wiki with decision trees so teams could self-serve for common scenarios
• Facilitated over 100 threat modeling sessions with engineering teams using STRIDE and PASTA methodologies, identifying 500+ design-level security risks before code was written. Built a library of secure-by-default patterns that teams could adopt to address recurring risk categories
• Designed the enterprise IAM solution integrating Okta SSO, hardware-backed MFA, and CyberArk privileged access management for 15,000+ users across the organization. The solution eliminated shared credentials and brought privileged session recording to all admin access
• Established and chaired the security architecture review board, evaluating 200+ project proposals over 3 years and catching 30+ insecure designs before any development work began. The review process added about 2 days to project timelines but prevented costly rework later
• Defined security evaluation standards for new technology adoption, reviewing cloud services, SaaS tools, and open-source libraries against a consistent set of data handling, authentication, and compliance criteria. Rejected about 15% of proposed tools based on security gaps
• Worked with the infrastructure team to design network segmentation using VPC peering and service mesh, along with mTLS for all internal service-to-service communication. This removed plaintext traffic from the internal network entirely
• Presented architecture proposals and risk assessments to the CISO and CTO, translating technical vulnerabilities into business impact scenarios with estimated financial exposure. These presentations drove 3 major security infrastructure investments totaling $5M
• Mentored 3 senior security engineers in architecture thinking, helping them move from hands-on implementation to designing systems and influencing engineering teams. All three now lead architecture reviews independently for their business units
• Designed the data classification framework that categorizes all company data into 4 sensitivity tiers with corresponding storage, encryption, and access control requirements. The framework gave engineering teams clear rules for handling each data type
• Evaluated and selected the service mesh implementation for the company's Kubernetes infrastructure, comparing Istio, Linkerd, and Consul Connect against security, performance, and operational complexity criteria. The chosen solution supported both mTLS enforcement and fine-grained authorization policies
