Small machine shops are taking on IT management without OT security expertise, and struggle to implement proper network segmentation (Purdue Model, VLAN ACLs, firewall rules) while maintaining workflow for engineers.
A guided SaaS platform that scans the existing network, identifies OT devices, auto-generates VLAN configurations and firewall rulesets for the shop's specific equipment, and continuously monitors for compliance drift. Includes templates for common CNC protocols and manufacturer-specific transfer methods.
Freemium - free network assessment, paid subscription ($100-300/mo) for ongoing monitoring, ruleset management, and compliance reporting
The Reddit signal is textbook acute pain: a sysadmin has inherited OT responsibility they're unqualified for, knows the risk (CNCs on flat network), and is actively seeking help. This pattern repeats across r/sysadmin, r/networking, and r/OTsecurity. The pain intensifies when compliance audits happen (CMMC, cyber insurance questionnaires, customer security assessments). However, many shops don't feel the pain until an incident or audit — awareness is the bottleneck, not severity.
~250K small manufacturers in the US (under 50 employees). If 10% have active IT/compliance pressure = 25K potential customers. At $200/mo average = $60M TAM. Adding MSPs (each serving 5-20 shops) could 3x the effective reach. This is a solid niche but not massive — it's a $50-200M opportunity, not a billion-dollar market on its own. Growth path requires expanding to mid-market manufacturing or adjacent verticals (food processing, water treatment).
$100-300/mo is in the sweet spot — it's less than one hour of a network consultant's time per month, and far cheaper than a compliance failure, insurance premium increase, or ransomware incident (average manufacturing ransomware cost: $1.2M). MSPs will pay if they can mark it up. The barrier is that many small shops haven't budgeted for OT security at all — you're creating a new budget line, not replacing an existing spend. CMMC requirements and cyber insurance questionnaires are the forcing functions that unlock willingness to pay.
This is the hardest dimension. Network scanning and device discovery is achievable (nmap, SNMP, protocol fingerprinting). Auto-generating VLAN configs and firewall rules is doable for common switch vendors (Cisco, Ubiquiti, Netgear). BUT: (1) the diversity of network hardware in small shops is enormous, (2) auto-pushing configs to live production networks is terrifying — one wrong rule kills CNC workflow, (3) OT protocol detection (EtherNet/IP, Modbus, FOCAS, MTConnect) requires deep domain knowledge, (4) continuous compliance monitoring needs an on-prem agent or sensor. A solo dev can build a useful assessment/recommendation tool in 8 weeks, but the full auto-config + monitoring platform is a 6-12 month effort with significant edge cases.
This is the strongest dimension. There is genuinely NO product serving small manufacturers with automated, self-service OT network segmentation at an SMB price point. Enterprise vendors (Claroty, Nozomi, Dragos) start at $30K+/year and require professional services. The closest competitor (TXOne) is still hardware-per-machine at $2K+ each. The gap is massive and structural — enterprise vendors have no incentive to move downmarket. You would be creating a new category.
Extremely strong recurring model: (1) compliance drift monitoring is inherently continuous — new devices get added, configs change, (2) compliance reporting is periodic (quarterly/annual audits), (3) network environments change as shops add machines, (4) threat landscape evolves requiring updated rules, (5) CMMC/insurance compliance is an ongoing requirement. Once segmentation is in place, the monitoring and compliance reporting creates genuine lock-in and ongoing value. Churn risk is low once operational.
- +Massive underserved market gap — no one serves small manufacturers with affordable, self-service OT segmentation
- +Strong compliance tailwinds (CMMC 2.0, cyber insurance requirements) creating urgency and willingness to pay
- +Excellent recurring revenue potential with compliance monitoring and drift detection
- +MSP channel multiplier — each MSP customer represents 5-20 end shops
- +Price point ($100-300/mo) is a no-brainer vs. consultant costs or incident costs
- !Technical complexity is high — auto-generating network configs across diverse hardware is brittle and dangerous if wrong; a bad rule can halt production
- !Market education problem: many target customers don't know they need this yet, requiring sales/content effort to create awareness
- !Enterprise vendors could release SMB tiers (unlikely near-term but possible if market proves out)
- !OT domain expertise is deep and narrow — founder needs real manufacturing networking experience or a co-founder who does
- !Deployment requires some on-prem component (agent/sensor) which complicates pure SaaS delivery and support

The actual 'competitor' — small shops cobble together consumer/prosumer gear
Start with a FREE network assessment tool only — no auto-configuration in v1. User installs a lightweight scanner (Docker container or single binary) on their network. It discovers all devices, identifies OT equipment (CNC, PLC, HMI) by protocol/fingerprint, maps current network topology, and generates a PDF report showing: (1) what's on the network, (2) what's dangerously co-mingled, (3) a recommended Purdue Model layout with specific VLAN assignments, and (4) copy-paste-ready firewall rules for their specific switch/firewall vendor. This is the 'aha moment' without the risk of touching live configs. The paid tier adds continuous monitoring, drift alerts, and compliance reporting.
Free network assessment PDF (lead gen) → $99/mo monitoring + drift alerts → $199/mo compliance reporting + audit-ready documentation → $299/mo managed ruleset updates + MSP multi-tenant dashboard → Professional services for complex deployments ($2K-$5K one-time)
8-12 weeks to free assessment tool generating leads, 16-20 weeks to first paid subscriber. The free assessment is the wedge — it demonstrates value immediately and creates natural upgrade pressure when the shop realizes they need ongoing monitoring. First $10K MRR likely at month 6-8 if targeting MSPs aggressively.
