A Clear Picture of Where Your Network Is and What to Do About It
Most infrastructure modernization projects fail not because the technology is wrong, but because the starting point wasn't fully understood. IVI's network assessment provides the foundation for every significant engagement — thorough discovery that produces better outcomes than moving directly from symptoms to solutions.
Get current-state documentation, prioritized risk assessment, and a sequenced remediation roadmap that reflects your operational reality.
Comprehensive network assessment that produces documentation, risk ratings, and actionable remediation plans.
Assessment First
Thorough discovery produces better outcomes than moving directly from symptoms to solutions
Design decisions made on incomplete information produce architectures that don't fit the environment. Migration plans that don't account for hidden dependencies produce outages. Security recommendations that don't reflect actual traffic patterns produce policies that break applications or leave real gaps unaddressed.
The Challenge
Organizations investing in infrastructure modernization often lack complete understanding of their current state, leading to failed projects and unexpected risks.
Incomplete or outdated network documentation
Hidden dependencies and configuration drift
Unknown security gaps and compliance risks
Invisible operational blind spots
What We Assess
Comprehensive analysis across six critical areas of network infrastructure and operations.
Software Currency & Lifecycle Risk
Software version inventory mapped against vendor end-of-support timelines and known CVE exposure with risk ratings.
Security Posture
Segmentation architecture, access control configuration, firewall rule quality, and network monitoring for security events.
Observability Coverage
Monitoring platform configuration, metric collection coverage, blind spot identification, and alert quality assessment.
WAN & Connectivity Architecture
Circuit inventory, carrier relationships, SD-WAN configuration, cloud connectivity design, and resilience testing.
Operational Model & Change Management
Real operational practices, change documentation, incident tracking, runbook coverage, and team capacity analysis.
Assessment Process
Structured 4-5 week engagement from scoping to actionable deliverables.
1
Scoping & Access Setup
Align on scope, obtain read-only access, schedule stakeholder interviews, and set up discovery tooling.
2
Discovery & Data Collection
Execute automated discovery, collect configurations and topology data, conduct targeted team interviews.
3
Analysis & Documentation
Analyze data, produce topology documentation, develop gap findings with risk ratings and business impact.
4
Report Delivery & Review
Deliver assessment package and conduct detailed review session with clear remediation guidance.
Assessment Deliverables
Documents your team can use and act on — not just observations, but actionable analysis.
Current-State Network Documentation
Physical and logical topology diagrams, complete device inventory with software versions, VLAN and subnet maps, WAN circuit inventory, and routing architecture documentation.
Gap Analysis & Risk Assessment
Prioritized findings by category with risk severity ratings and business impact mapping covering infrastructure, security, observability, and operational gaps.
Remediation Roadmap
Sequenced remediation plan that prioritizes findings by risk and maps them to realistic project phases reflecting your budget cycles and operational constraints.

Choose the assessment scope that matches your specific needs and timeline
Recommendation: keep to one or two short sentences.
Network Infrastructure Assessment
Covers topology, device inventory, software currency, WAN architecture, and redundancy design.
Best Fit
Organizations planning technology refresh or responding to end-of-life notifications.
Security Posture Assessment
Infrastructure assessment plus focused review of segmentation, firewall configuration, and access control design.
Best Fit
Organizations preparing for PCI DSS, SOC 2, or other compliance requirements with network security scope.
Full-Scope Assessment
Combines infrastructure, security, and observability assessment with operational model review.
Best Fit
Starting point for comprehensive network modernization programs or complete network state review.
Targeted Assessment
Focused assessment of specific areas — WAN resilience, cloud connectivity, IoT segmentation, or SD-WAN performance.
Best Fit
Organizations with specific concerns rather than broad modernization initiatives.
Why IVI
Assessments that produce documentation, risk ratings, and sequenced remediation plans
Actionable deliverables, not just observations
We produce topology diagrams that are accurate and current, software inventory specific to device and version, and findings that reflect operational reality.
Complete Documentation
Most organizations find this is the most complete and current documentation of their network that has ever existed.
Risk-Rated Findings
Each finding is rated by risk severity and mapped to business impact — not theoretical recommendations.
Realistic Roadmaps
Remediation plans reflect your budget cycles, operational constraints, and change management capacity.
Foundation for successful engagements
Organizations that complete an IVI assessment and proceed to engagement benefit from engineers who already understand their environment.
No Re-Discovery
Design work starts from accurate current-state knowledge rather than discovery that typically takes the first weeks of a project.
Honest Analysis
We don't use assessments to sell predetermined approaches. If your infrastructure is better than expected, we'll tell you.

FAQs
Frequently Asked Questions
Common questions about network assessment services.
We have a network diagram from 5 years ago. Is that helpful input to the assessment?
It's a starting point. We use existing documentation as input where it exists and validate and update it during discovery. Most organizations find that their existing documentation has meaningful gaps by the time an assessment is completed, particularly in areas that have changed over time without documentation updates.
We have a specific compliance audit coming up in 90 days. Can an assessment be completed in time?
Yes, with appropriate scope prioritization. We can conduct a targeted security posture assessment focused on compliance domains most relevant to your upcoming audit in 2-3 weeks. We sequence the work to deliver compliance-relevant findings first.
Do you need to put anything on our network to conduct the assessment?
For discovery, we use read-only SSH/SNMP access to network devices and access to management platforms where they exist. We may deploy a lightweight discovery agent for environments where direct device access is limited. We do not make any configuration changes to your infrastructure during an assessment engagement.
We're worried about what an assessment might find. What if the findings are worse than expected?
This is a common concern — and the right response is to find out before the findings surface in an incident or audit. Organizations that resist assessments tend to have the most significant gaps, while those that understand their current state are substantially better positioned to make good decisions. An unfavorable assessment finding is a remediation project; an unfavorable incident is a business impact event.
What happens after the assessment if we want IVI to help with remediation?
The remediation roadmap from the assessment becomes the project plan for subsequent engagement. Because our engineers conducted the assessment, there's no re-discovery period — we move directly to design based on the current-state documentation we produced.
How long does a typical network assessment take?
Standard full-scope assessment takes 4-5 weeks from kickoff to report delivery. Targeted assessments take 2-3 weeks depending on scope. Expedited assessments are available for organizations with urgent compliance or project timelines, with scope constraints and compressed discovery windows.
