Affordable Steps for Maritime Cybersecurity Compliance: MAD Security Maritime Town Hall Recap – November 2025

Watch the November Maritime MAD Security Town Hall Webinar replay 👇

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. 

Key Takeaways Recap: What Every Maritime Operator Should Know

	Start With Scope Reduction One 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 MFA Identity 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 Policies Technical 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 Access Vendors 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 Detection Building 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.
