In the November 2025 MAD Security Town Hall, Cliff Neve addressed a critical topic for maritime operators and government contractors: how to cost-effectively comply with the Coast Guard’s cybersecurity mandates under the Maritime Transportation Security Act (MTSA).
This session was focused on helping DIB-aligned organizations meet inspection requirements while avoiding unnecessary spending. MAD Security, trusted across the defense industrial base for its commitment to NIST-based operations and 24/7 U.S.-based SOC services, shared exactly where to focus your efforts for the greatest impact.
From network segmentation to policy documentation, Cliff outlined a 30-day roadmap filled with smart wins that lower cyber risk and improve audit readiness without high-cost investments.
Start With Scope ReductionOne of the most strategic and cost-saving steps is reducing your regulated scope. The Coast Guard only requires cybersecurity controls for systems directly supporting MTSA functions. Use network segmentation and asset inventories to isolate regulated systems, reduce audit exposure, and avoid overcommitting tools or technology too early. |

Clean Up Identity Access and MFAIdentity hygiene remains the most common entry point for cyber threats. Remove dormant accounts, enforce least privilege, and enable multi-factor authentication (MFA) for high-risk access including admin accounts and remote systems. Built-in MFA in Microsoft 365 and Google Workspace can provide strong protection with minimal cost. |
|
Write Inspector-Friendly PoliciesTechnical controls are important, but policies are what auditors review first. Create and maintain governance documents that define system owners, critical assets, access control strategies, and incident response roles. These policies help during inspections and guide long-term security planning. |
|
Control Vendor AccessVendors often have remote access to operational technology systems. This creates a high-risk area if unmanaged. Include cybersecurity requirements in vendor contracts, use unique credentials, and ensure access logging is in place. When possible, limit remote access or add segmentation to isolate systems. |
|
Avoid DIY SOCs and Choose Smart DetectionBuilding a 24/7 Security Operations Center internally is time-consuming, expensive, and often unsustainable. MAD Security recommends SOC-as-a-Service as a smarter alternative. Logging, detection, and threat response can be handled by experts at the cost of a single internal security hire, while providing enterprise-level protection and compliance visibility. |
Ranked among the Top 250 MSSPs globally for four consecutive years, MAD Security provides real operational and compliance outcomes for port authorities, vessel operators, marine transportation facilities, and government contractors.
Maritime-focused advantages include:
| U.S.-based, 24/7 SOC located in Huntsville, Alabama | |
| Deep experience securing maritime, defense, and federal environments | |
| Expertise in NIST frameworks, DFARS, CMMC, and Coast Guard cybersecurity requirements | |
| Full-spectrum cybersecurity offerings including GRC, SOCaaS, MDR, VCM, risk assessments, and pen testing | |
| Veteran-led, SDVOSB certified, mission-aligned leadership | |
| Proven ability to simplify compliance while improving operational resilience |
Delaying preparation for cybersecurity compliance creates significant business risks:
| Failed audits or denied authorizations | |
| Contract loss or inability to bid competitively | |
| Unbudgeted remediation costs and reputational damage |
Taking early action allows you to build strong documentation, segment networks, and implement controls thoughtfully and effectively. It also puts your organization in a stronger position for inspections, vendor requirements, and operational resilience. With Coast Guard enforcement increasing through 2026, organizations that start now will avoid last-minute stress and benefit from improved compliance posture.
MAD Security is here to support maritime operators with the proven tools, services, and guidance needed to meet Coast Guard requirements with confidence. Schedule a consultation today and take the first step toward lasting maritime cybersecurity compliance.
Cybersecurity is a journey that demands consistent focus and disciplined execution. The maritime sector is facing real threats, and the Coast Guard’s expectations are only increasing.
