OT Security and Industrial Cybersecurity
Modern manufacturing operates at the intersection of information technology and operational technology — two environments with fundamentally different security requirements that are increasingly connected. A breach in IT can reach the production floor. A compromised OT system can halt output, destroy equipment, or expose trade secrets that took decades to develop. Vigil Cyber delivers security programs that address both sides of this boundary, with specialized expertise in CMMC compliance for defense industrial base contractors.
Two Worlds Converging — One Security Program
Modern manufacturing connects systems that were never designed to communicate. IT networks carry business data, email, and cloud applications. OT networks control physical processes — machines, conveyors, sensors, and production lines. As these environments merge, the security gaps between them become the primary attack surface. Addressing that convergence is where manufacturing security begins.
IT Environment
Frequent software updates and patches
IT systems are designed to accept regular security patches, OS updates, and software upgrades — keeping the attack surface current.
Standard security tooling applies
EDR agents, vulnerability scanners, and SIEM platforms integrate directly with IT infrastructure without disrupting operations.
Availability interruptions are tolerable
Scheduled maintenance windows, reboots for patches, and brief outages are manageable in IT environments.
Confidentiality and integrity are primary concerns
Protecting data from unauthorized access and ensuring system integrity are the core IT security objectives.
OT Environment
Legacy systems that cannot be patched
Many OT systems run operating systems that are years past end-of-life and cannot accept security patches without risking production stability.
Standard agents cannot be installed
PLCs, SCADA systems, and industrial controllers cannot run endpoint security agents — requiring network-level monitoring instead.
Downtime is operationally unacceptable
Production systems must run continuously. Security measures that could interrupt processes require extensive testing and maintenance window coordination.
Safety and availability are primary concerns
In OT environments, a compromised system can cause physical damage, safety incidents, or halt production — the stakes go beyond data loss.
Why Convergence Creates Unique Risk
The connection between IT and OT that enables remote monitoring, predictive maintenance, and supply chain integration also creates pathways for attackers to move from a compromised email account to a production floor control system. IT security tools frequently cannot see or interact with OT environments. OT systems cannot accept the patches and agents that IT security depends on. Vigil Cyber bridges this gap with monitoring and controls that address both sides of the convergence boundary — without disrupting the production processes your business depends on.
Threats Targeting Manufacturers Today
Manufacturing has become one of the top-targeted sectors in cybersecurity, surpassing financial services in attack volume in recent years. The combination of valuable intellectual property, operational disruption leverage, and historically under-invested security programs makes manufacturing an attractive target for both nation-state actors and financially motivated criminal groups.
Intellectual Property Theft and Industrial Espionage
Proprietary manufacturing processes, product designs, material formulations, and pricing models represent the competitive core of most manufacturers. Nation-state actors — particularly those aligned with China, Russia, and Iran — specifically target manufacturers to steal IP that would take rivals years to develop independently. Insider threats and compromised vendor access are the most common pathways to this data.
OT and ICS Attacks on Production Systems
Operational technology environments — SCADA systems, PLCs, industrial control systems, and the networks connecting them — were designed for reliability, not security. Many run legacy operating systems that no longer receive patches, communicate over unencrypted protocols, and are increasingly connected to IT networks and cloud systems for remote monitoring. An attacker who reaches the OT environment can halt production, damage equipment, or manipulate processes in ways that are difficult to detect and potentially dangerous.
Supply Chain Compromise
Manufacturing operations depend on complex supplier ecosystems. A compromised component supplier, software vendor, or logistics partner becomes a trusted entry point into your environment. Supply chain attacks are particularly difficult to detect because the malicious activity arrives through legitimate channels — software updates, remote support sessions, and vendor-provided hardware.
Ransomware Disrupting Operations
Ransomware groups have discovered that manufacturing environments are highly sensitive to downtime — every hour of halted production has a calculable cost in lost output, contract penalties, and customer relationship damage. This operational pressure maximizes extortion leverage. Groups like LockBit, BlackCat, and Cl0p have specifically targeted manufacturers, encrypting both IT systems and OT environments to maximize their demands.
How We Protect Manufacturing Operations
Effective manufacturing security requires a partner who understands that production continuity is non-negotiable. Our security services are deployed with the operational constraints of industrial environments in mind — protecting both IT and OT without disrupting the production processes your business depends on.
24/7 SOC Monitoring
24/7 Security Operations Center
Monitor IT and OT environments continuously for threats that cross the network boundary.
Our SOC analysts monitor both your enterprise IT environment and the industrial network boundary around the clock. We correlate signals from IT systems, OT monitoring tools, and network infrastructure to detect lateral movement, anomalous process behavior, and active threat indicators — providing detection and response that covers both sides of the IT/OT convergence.
Compliance Monitoring
Compliance and Risk Management
Build and maintain the CMMC documentation that defense contracts require.
CMMC Level 2 requires a System Security Plan, Plan of Action and Milestones, and documented evidence of all 110 NIST SP 800-171 controls. Our compliance monitoring service maintains this documentation continuously — not just at assessment time — and tracks your progress against the control baseline as your environment evolves. We build what assessors need to see.
Endpoint Detection & Response (EDR/XDR)
Endpoint Detection and Response
Protect engineering workstations, MES systems, and enterprise endpoints from ransomware.
Engineering workstations running CAD software, MES platforms, and ERP systems hold the most sensitive data in a manufacturing environment. Our endpoint protection deploys behavioral AI that detects ransomware, malware, and unauthorized data exfiltration on these endpoints — with lightweight agents that do not interfere with production software.
Cloud & Identity Security
Cloud Security and Identity
Control remote access to OT systems and cloud-connected industrial platforms.
Remote access to industrial systems has expanded dramatically — for vendor support, remote monitoring, and distributed operations. Our cloud security service enforces zero-trust access policies for remote connections, manages multi-factor authentication for privileged accounts, and monitors for identity-based attacks against the accounts that control your most sensitive systems.
Advanced Email Security
Advanced Email Security
Stop phishing campaigns targeting engineers, procurement staff, and executives.
Spear phishing campaigns targeting manufacturing organizations are frequently designed to harvest credentials for ERP systems, engineering platforms, and corporate email. Our advanced email security stops these attacks with AI-powered detection, BEC protection, and impersonation alerting — reducing the risk that a well-crafted phishing email becomes an attacker's entry point.
Patch & Vulnerability Management
Patch and Vulnerability Management
Close IT vulnerability windows while developing mitigation strategies for unpatchable OT.
IT patching in manufacturing must account for production schedules, maintenance windows, and system interdependencies. Our patch management service manages IT patching intelligently — prioritizing by exploitability and risk, coordinating with production schedules, and developing compensating controls for industrial systems that cannot accept standard patch procedures.
CMMC and the Defense Industrial Base
The Cybersecurity Maturity Model Certification (CMMC) program fundamentally changed the compliance landscape for defense contractors. CMMC 2.0 requires prime contractors and subcontractors who handle Controlled Unclassified Information (CUI) to achieve and maintain specific CMMC levels — and to have that achievement verified by a third-party assessor for Level 2 requirements.
NIST SP 800-171 — the technical foundation of CMMC Level 2 — contains 110 security requirements across 14 domains. Most manufacturers who handle CUI have gaps in multiple domains. Vigil Cyber conducts gap assessments against NIST 800-171, implements the technical controls required, and builds the System Security Plan (SSP) and Plan of Action and Milestones (POA&M) that CMMC assessors expect to see.
For manufacturers outside the defense industrial base, NIST CSF and ISO 27001 provide the risk management frameworks that customers, insurers, and regulators increasingly expect — and that differentiate your firm from competitors who treat security as an afterthought.

Cybersecurity Maturity Model Certification (CMMC 2.0)
CMMC 2.0 establishes three levels of cybersecurity requirements for defense contractors handling Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). Level 2 aligns with NIST SP 800-171 and requires third-party assessment for contracts involving CUI. Vigil Cyber prepares manufacturers for CMMC assessment and maintains the documentation program assessors require.
NIST Cybersecurity Framework
The NIST CSF provides a risk-based approach to cybersecurity organized around five functions: Identify, Protect, Detect, Respond, and Recover. It is the most widely adopted cybersecurity framework in U.S. manufacturing and is increasingly referenced by cyber insurers, prime contractors, and enterprise customers as a minimum standard for suppliers.
ISO/IEC 27001 Information Security Management
ISO 27001 provides a formal management system for information security — including the policies, procedures, and controls required for certification. International customers and European supply chain partners frequently require ISO 27001 compliance or certification. Vigil Cyber supports manufacturers pursuing ISO 27001 certification with gap assessment and control implementation.
NIST SP 800-171 Controlled Unclassified Information
NIST SP 800-171 contains 110 security requirements that apply to any non-federal organization that handles CUI — a category that includes technical data, export-controlled information, and defense-related materials. Defense contractors are contractually required to comply, and the Department of Defense is actively enforcing these requirements through CMMC.
