Network redundancy checker
TL;DR
Browser-based network validation tool for SMB IT admins and MSPs that auto-scans uploaded topology diagrams (or API-connected firewalls/switches) for loops, redundancy gaps, and misconfigurations so they can resolve issues in <5 minutes with step-by-step fixes and cut outage-caused downtime by 70%
Target Audience
Junior network engineers & IT sysadmins managing enterprise infrastructure
The Problem
Problem Context
Network engineers and IT admins need to safely connect firewalls and switches without creating loops or causing outages. They lack confidence in their manual redundancy setups, especially when using active-standby firewalls. Current methods rely on trial-and-error or expensive consultants, which are error-prone and time-consuming.
Pain Points
Users struggle with misconfigurations that lead to network loops or unexpected downtime. They waste hours manually validating redundancy setups, often without clear guidance. Failed attempts force them to hire consultants or risk costly outages, creating frustration and lost productivity.
Impact
A single misconfiguration can cause hours of downtime, costing businesses thousands in lost revenue. The fear of outages slows down network upgrades and expansions. IT teams spend excessive time troubleshooting instead of focusing on strategic projects, leading to burnout and inefficiency.
Urgency
Network changes happen frequently, and each change introduces risk. Without validation, engineers cannot confidently deploy updates. The problem cannot be ignored because outages directly impact business operations and customer trust.
Target Audience
Small to mid-sized businesses with IT teams, managed service providers (MSPs), and network engineers at companies without dedicated network architects. These users manage firewalls, switches, and redundancy setups but lack advanced tools for validation.
Proposed AI Solution
Solution Approach
Network Guard is a browser-based tool that automatically validates firewall and switch configurations in real-time. It detects loops, redundancy gaps, and misconfigurations before they cause outages. Users upload their network topology (or connect via API), and the tool provides instant feedback with actionable fixes.
Key Features
- Redundancy Checker: Ensures active-standby firewalls and switches are properly configured to failover without disruption.
- Step-by-Step Fixes: Provides clear instructions to resolve issues, even for non-experts.
- Change Tracking: Monitors network changes over time to alert users of risky modifications.
User Experience
Users drag-and-drop their network diagram into the tool or connect it via API. The system instantly highlights risks (e.g., 'Loop detected between Switch A and B'). They follow guided fixes or export reports for their team. The dashboard shows real-time health scores and historical change logs, reducing manual validation time to minutes.
Differentiation
Unlike complex vendor tools or free CLI commands, Network Guard offers a simple UI with no installation. It combines topology validation + redundancy checking in one place, while competitors focus on either monitoring or configuration management separately. The tool is vendor-agnostic, supporting Cisco, Juniper, Palo Alto, and others.
Scalability
Starts with SMBs (1-50 users) and scales to enterprise teams (50+ users) with seat-based pricing. Adds API integrations for larger networks and supports team collaboration features (e.g., shared dashboards). Can expand into related areas like security policy validation or bandwidth optimization.
Expected Impact
Eliminates outages caused by misconfigurations, saving businesses thousands in downtime costs. Reduces IT team stress by automating validation, freeing time for strategic projects. Provides audit trails for compliance and simplifies onboarding for new engineers.
