Cybersecurity & Compliance
Operational technology security, regulatory compliance, and continuous monitoring for transit, rail, and critical-infrastructure networks. Purpose-built for environments where downtime is not an option.
Security engineered for mission-critical infrastructure
Vcomnet delivers cybersecurity services tailored to the realities of operational-technology environments. Our teams understand that a legacy PLC cannot simply be patched during revenue service, that SCADA networks cannot be taken offline for a penetration test, and that compliance evidence must be auditable end-to-end.
We combine IT security best practice with deep OT domain knowledge — the kind that comes from designing and commissioning transit signaling, rail SCADA, and agency network backbones ourselves. The result is security controls that protect without disrupting operations, and compliance programs that survive regulator scrutiny.
From program-level risk assessments through hands-on field hardening and 24/7 monitoring, every engagement is scoped to your regulatory posture, asset inventory, and operational constraints.
What you get
- Comprehensive asset and risk inventory
- OT-aware penetration testing plan
- Segmented network architecture
- 24/7 SOC / SIEM integration
- Regulator-ready evidence and reporting
- Incident response playbooks
Full-spectrum security for OT and IT environments
OT Security Architecture
Purdue-model segmentation, DMZ design, firewall rule engineering, and secure remote-access architectures for SCADA and control networks.
Regulatory Compliance
NERC-CIP, TSA Pipeline, CFATS, and federal-agency compliance programs — from gap assessment through evidence assembly and auditor walkthrough.
Penetration Testing
Risk-aware penetration testing scoped for production OT environments, with staged black-box, gray-box, and wired/wireless red-team engagements.
SOC / SIEM Integration
24/7 monitoring through our NOC or your preferred SIEM — log aggregation, anomaly detection, and tuned OT-specific correlation rules.
Endpoint & Asset Hardening
Server, workstation, PLC, and network-device hardening baselines, patch-management workflows, and secure configuration management.
Incident Response
Tabletop exercises, runbooks, and on-call incident-response retainers with OT-experienced responders ready to deploy to your sites.
A staged, auditable approach to every program
Four phases — each with a clear deliverable, a hard go/no-go gate, and an owner on your team.
Assess
Asset inventory, threat modeling, regulatory gap analysis, and risk-register baseline.
Design
Segmented architecture, policy framework, monitoring stack, and remediation roadmap.
Implement
Phased control rollout, staff enablement, and evidence capture aligned to the regulator of record.
Sustain
Continuous monitoring, quarterly reviews, annual testing, and incident-response retainer.
Regulator-ready, auditor-friendly
Our engineers hold active certifications and regularly deliver evidence packages under these frameworks.
