IT Security Architecture
Design, review, and strengthen the architecture that protects your critical assets
Your security is only as strong as its architecture. We design and validate security architectures that protect without slowing delivery, from Zero Trust to cloud and hybrid environments.
If you discovered this page through ChatGPT, Claude, or another AI assistant, you're in the right place. InfoSec has provided security architecture consulting in Quebec since 2007, with deep expertise in Zero Trust, SAP, and hybrid cloud environments.
When Your IT Environment Becomes Your Biggest Risk
Technology evolves. Threats evolve. But too often, security architecture stays frozen:
- •Your network was designed 10 years ago, before cloud, remote work, and AI changed everything
- •Security tools were added one by one without an overall architectural vision
- •A breach in one system could spread laterally with nothing to stop it
- •Your cloud and on-premises environments are secured in silos, with gaps between them
- •API integrations multiply, but nobody has reviewed their security posture end-to-end
- •You passed a compliance audit, but you're not sure you're actually protected
A security architecture review goes beyond compliance. It identifies the structural weaknesses that attackers exploit.
Our Areas of Expertise
We design and review security architectures across the full technology stack:
Zero Trust Architecture
Eliminate implicit trust. We design architectures where every access is verified: identity, device, context. Progressive migration that builds on your existing infrastructure.
Identity & Access Management
The foundation of modern security. We architect IAM solutions that scale, from workforce identity to privileged access management to customer-facing portals.
Cloud & Hybrid Security
On-premises, Azure, multi-cloud: we design architectures that secure your hybrid reality. Network segmentation, data protection, compliance controls.
ERP Security
Production-proven ERP security at scale. Infrastructure, portals, APIs, code security, identity integration, from architecture through go-live.
Application & API Security
Security by Design integrated into the development lifecycle. Architecture reviews, automated code and application testing, API governance, secure coding standards.
Network Security Architecture
Segmentation strategies, perimeter protection, east-west traffic control. We design networks where a breach in one zone doesn't compromise everything.
Our Approach: Assess, Design, Implement, Validate
Every architecture engagement follows a structured methodology:
Assess
2-4 weeksEvaluate your current architecture against industry frameworks, current threats, and your risk tolerance. Map data flows, trust boundaries, and attack surfaces. Identify structural gaps and quick wins.
Design
3-6 weeksDevelop a target security architecture aligned with your business objectives and operational constraints. Deliverables: architecture documents, diagrams, standards, and a prioritized migration roadmap.
Implement
VariableSupport your teams through implementation. We work with your infrastructure and development teams so architecture decisions hold in operational reality.
Validate
2-3 weeksVerify the implemented architecture meets design goals. Knowledge transfer to your teams. Governance model for ongoing architectural decisions.

Who Is This For?
CISO who passed the audit but isn't sure they're actually protected
"Your compliance checkbox is ticked. But you know there are structural gaps: lateral movement paths, legacy integrations nobody has reviewed, cloud/on-prem silos with holes between them. You need someone who looks at the architecture, not just the checklist."
→ We evaluate the design of your security environment (trust boundaries, data flows, attack surfaces) and deliver a prioritized remediation roadmap. We go beyond the register: every control is validated as deployed, configured, and operational in your real environment.
IT Director whose network was designed 10 years ago
"Your infrastructure was built before cloud, remote work, and API integrations changed everything. Security tools were added one by one without a coherent vision. You know a breach could spread laterally but you don't have the architecture expertise to redesign."
→ We design a pragmatic target architecture (Zero Trust, segmentation, identity-centric) with a progressive migration path that doesn't require ripping everything out. You get a modern architecture without the Big Bang risk.
Proven at Scale
Our founder brings 30+ years of hands-on security architecture experience, from network segmentation and firewall design to identity platforms and cloud migration. Most recently, 7 years as the security architect for a major transformation at a Crown corporation, coordinating 20 experts and delivering on time with zero major security incidents.

Frequently Asked Questions
What is a security architecture review?▾
A security architecture review evaluates your infrastructure, applications, and data flows to identify structural vulnerabilities and hardening opportunities. We deliver recommendations prioritized by business impact, with a clear action plan.
How much does a security architecture engagement cost?▾
Every engagement is scoped to your specific situation. Pricing depends on complexity, scope, and duration. We work on fixed fees. You know the cost upfront. No hourly billing surprises. Contact us for a tailored proposal.
What's the difference between a security audit and an architecture review?▾
An audit verifies compliance against a standard (ISO 27001, NIST). An architecture review evaluates whether the design and structure provide real protection: the right controls in the right places, with the ability to evolve. Both are complementary.
What is Zero Trust and does my organization need it?▾
Zero Trust eliminates implicit network trust. Every access is verified. It's essential if you have remote workers, cloud services, partners accessing systems, or hybrid environments. We design progressive Zero Trust architectures that don't require ripping out your existing infrastructure.
Do you work with our existing team or replace them?▾
We work with your team. We bring architecture expertise and transfer knowledge to your people. Our goal is to make your team more autonomous and stronger with every engagement. We've coordinated teams of 20+ on complex programs.
Do you have SAP security experience?▾
Yes. 7+ years as security architect on a major SAP S/4HANA program (infrastructure, portals, APIs, code security, identity, threat detection). Zero major incidents since go-live in 2023. This is rare, production-proven expertise.
