Security Architecture
Security controls added after the fact are inconsistent, hard to audit, and leave gaps across network, cloud, and identity that compound over time.
Our Approach
Integrate security into architecture from the beginning — threat-informed, risk-aligned, and built to be operable by the team running it.
What This Service Covers
Security architecture advisory for organizations building new infrastructure or hardening what they have. Engagements are grounded in actual threat scenarios and business risk — not checkbox compliance.
Work spans network security design, zero-trust architecture, identity and access management, cloud security posture, endpoint and data protection strategy, and security architecture review of proposed or existing designs.
Scope areas
Zero-trust architecture Identity-first access model design. Micro-segmentation strategy for on-prem and cloud. Conditional access policy design. Application-layer access controls (ZTNA, BeyondCorp-style). Integration with existing IAM and directory services.
Network security design Firewall architecture and zone design. East-west and north-south traffic control. IDS/IPS placement. Secure remote access (ZTNA vs VPN trade-offs). DNS security and DNS-layer filtering. DDoS protection strategy.
Identity and access management IAM architecture for on-prem and cloud (AD, Entra ID, Okta, AWS IAM). Least-privilege design and role consolidation. Privileged access management (PAM) — CyberArk, BeyondTrust, or open-source alternatives. MFA strategy and phishing-resistant authentication.
Cloud security posture CSPM alignment (AWS Security Hub, Microsoft Defender for Cloud, GCP SCC). Security group and policy audit. Data residency and encryption at rest/in transit. Secrets management (Vault, AWS Secrets Manager, Azure Key Vault).
Security architecture review Independent review of a proposed or existing architecture. Findings report with risk rating, gap identification, and prioritized recommendations. Suitable for pre-audit readiness or before major infrastructure changes.
Compliance alignment Map security architecture to specific control frameworks (ISO 27001 Annex A, PCI DSS 4.0, NIST CSF, CIS Controls). Identify evidence gaps and recommend controls that satisfy multiple frameworks simultaneously.
Delivery Models
Remote Consultation
Architecture review calls, design decision sessions, or threat-modelling workshops. Deliverable: written findings and recommendations after each session.
Architecture Review (Fixed Scope)
Point-in-time review of an existing or proposed security architecture. Structured findings report with risk ratings and recommendations. Typically 1–2 weeks.
Remote Support Retainer
Monthly hours for ongoing security architecture support — change reviews, new design assessment, pre-audit checks, and escalation support for the security team.
Engineer Basis (Project)
Full security architecture engagement: threat landscape assessment, current-state gap analysis, target-state design, and implementation roadmap. Remote-led. Typical scope: 4–8 weeks.
Typical Engagement Formats
| Format | Best for | Typical Duration |
|---|---|---|
| Security Architecture Review | Pre-audit or pre-migration validation | 1–2 weeks |
| Zero-Trust Design | Identity-first access model for hybrid env | 3–6 weeks |
| IAM Architecture | Consolidate and harden identity and access | 2–4 weeks |
| Cloud Security Baseline | CSPM + control baseline for AWS/Azure/GCP | 2–3 weeks |
| Retainer Advisory | Ongoing support for security architecture | Monthly |
