Architecture baseline
Sites, topology, network services, routing, wireless, WAN, cloud connectivity, internet edges, providers, platforms, and dependencies.
IA-04 / Infrastructure Assessment & Roadmap
Infrastructure assessment and roadmap for an owned target state.
We create a defensible view of how the infrastructure works today, where it creates risk or friction, and which changes deserve priority. The assessment connects network security, wired and wireless access, WAN and SD-WAN, cloud connectivity, resilience, lifecycle, documentation, and operating ownership.
Engagement trigger
Growth, acquisition, leadership change, recurring instability, aging platforms, poor documentation, or a major investment requires a reliable architecture baseline.

Decisions this work supports
Resolve the architecture questions before they become implementation constraints.
- 01
What is actually in place—and what depends on it?
Establish a trustworthy architecture baseline across topology, services, providers, platforms, sites, traffic, operations, and ownership.
- 02
Which conditions materially affect risk and performance?
Separate cosmetic inconsistency from technical debt that changes security, resilience, scalability, supportability, or cost.
- 03
What should change first?
Sequence stabilization, standards, lifecycle, architecture, and modernization work around dependencies, capacity, value, and risk.
Architecture scope
Connected disciplines, one design context.
The exact boundary is agreed around the decision. Relevant dependencies remain visible even when they sit outside the hands-on scope.
Security & resilience
Trust boundaries, access, segmentation, management, single points of failure, recovery dependencies, visibility, and failure behavior.
Operations & lifecycle
Ownership, monitoring, configuration governance, documentation, support boundaries, software and hardware lifecycle, and change practices.
Target state & investment
Architecture principles, capability gaps, options, sequencing, dependencies, decision points, estimated effort bands, and roadmap governance.
Engagement sequence
A controlled path from uncertainty to an owned design.
- 01
Inventory
Collect available diagrams, inventories, configurations, provider information, standards, incidents, plans, and stakeholder context.
Evidence index - 02
Validate
Reconcile documentation with technical evidence and interviews; identify uncertainties, dependencies, and missing ownership.
Validated current state - 03
Evaluate
Assess security, resilience, performance, scalability, lifecycle, operations, documentation, and architecture consistency.
Findings and debt register - 04
Prioritize
Define target principles and sequence stabilization, risk reduction, standards, redesign, refresh, and modernization work.

Engagement fit
A useful entry point when…
- Documentation no longer reflects the environment or cannot support a major decision
- Infrastructure has accumulated through growth, acquisition, isolated projects, or repeated tactical fixes
- Leadership needs a defensible investment sequence rather than a replacement wish list
- Security, network, application, and operations teams have different views of the current state
Questions before scoping
Practical answers, before the work begins.
01Is this a vulnerability assessment?
Not by itself. This work evaluates infrastructure architecture, resilience, lifecycle, security design, operations, dependencies, and technical debt. Vulnerability scanning or testing can be added when it supports the objective.
02What if our documentation is incomplete?
That is common and often part of the reason for the engagement. Available records are reconciled with technical evidence and stakeholder knowledge, and uncertainty is documented rather than hidden.
03Will the roadmap include product recommendations?
It can when product decisions are necessary and enough requirements are available. The primary output is an architecture and investment sequence; product selection follows documented fit rather than replacing the design process.
04Can the assessment cover only part of the environment?
Yes. It can focus on a region, set of sites, campus network, wireless estate, WAN, security architecture, cloud connectivity, or another defined boundary, provided the important external dependencies remain visible.

Start with the decision
Bring us the decision behind infrastructure assessment & roadmap.
A high-level description is enough to begin defining requirements, boundaries, dependencies, and the right architecture output.
Engagements can be delivered remotely, on site, or through a hybrid model. Location, scheduling, site access, and any travel requirements are agreed during scoping.
