Sean McAllister

Sean McAllister manages all delivery of Federal Governance, Risk Management and Compliance services to Securicon’s customers. These include both Federal and commercial customers and are in increasing demand, especially with the current stress on compliance with NIST SP 800-171 and Cybersecurity Maturity Model Certification (CMMC).

After graduating from the University of Maryland with a degree in communications, Sean began as a Securicon Cybersecurity Analyst, then earned a promotion to Managing Consultant, and accepted increasing responsibility in Program Management. During this time, he continued his academic studies and earned an M.S. in Cyber Security, also from University of Maryland. Sean’s hard work resulted in customer success, and customers increasingly expanded their demands for the services of his team, which led to Sean becoming the Director of the Risk Management Services Branch. His branch continued to grow through customer demand and he now manages the Risk Management Division through multiple Directors of Risk Management Branches. However, Sean continues to maintain a heavy schedule of direct support to customers.

Sean provides Information Security consulting services to Securicon’s customers through testing, auditing and data analytics, and vulnerability assessment. In addition to this experience, he has assisted clients in creating Disaster Recovery Plans, and Business Continuity and Incident Response procedures. He has worked with numerous Federal clients throughout all stages of the security authorization process, applying the NIST methodology, including investigation, analysis, and documentation as a Federal Information Security Management Act (FISMA) compliance consultant. Sean is also a skilled technical writer and has experience in developing manuals, procedures, and policy documentation. He is always engaged in a number of business development activities including proposal development and responses to Requests for Proposals (RFPs). His skill set was also utilized during the creation of storyboard outlining and content detailing security policy development, security processes and procedures to be implemented during transition and implementation. His development of a regulatory requirement tracking matrix was used as the basis for the work plan to meet NIST/FISMA requirements. His experience in conducting Federal system assessments and authorizations has provided him with extensive knowledge of all stages of the security authorization process and of security documentation, to include System Security Authorization Agreement (SSAA), Concept of Operations, Security Waivers, Plan of Action and Milestones (POA&M), Information System Contingency Plans (ISCP), and System Security Plans (SSP). Mr. McAllister also has experience working with Digital Forensics Tools and Intrusion Detection and Prevention tools.
