As a Defense Intelligence Base (DIB) contractor, managing insider threat reporting and ensuring compliance with SEAD 3 (Security Executive Agent Directive 3) requirements can be both complex and time-consuming. After implementing the 351X Platform – Counterintelligence & Compliance Case Management System at 3GIMBALS, I have found it to be an invaluable resource for streamlining these responsibilities and strengthening our overall security posture in my role as the company’s Facility Security Officer (FSO). The 351X system offers an intuitive, secure, and well-organized framework for tracking, managing, and documenting insider threat and counterintelligence activities. By consolidating essential workflows into a single, compliant platform, it helps ensure that all reporting requirements are fulfilled efficiently and consistently. A major advantage of the system is its ability to automate routine compliance tasks while upholding the strict standards required by SEAD 3. Its integrated case management and reporting features make it straightforward to organize information, maintain thorough audit trails, and generate reports for leadership or government review. From a user standpoint, the interface is clean, logical, and responsive, making it accessible even for those who are new to counterintelligence compliance. The 351X team also delivers excellent support and is open to feedback. Overall, 351X has become a vital component of how we manage our Insider Threat Program at 3GIMBALS, enabling us to stay ahead of compliance requirements and focus on proactive security measures. I highly recommend 351X to other DIB contractors looking for a dependable, secure, and purpose-built solution for counterintelligence and SEAD 3 reporting.
