Cyber security

Services ensure the determent, protection, detection, and response by providing threat analysis, network defense architectures, intrusion detection, vulnerability assessments and risk mitigation

Cyber Security is evolving from just using antivirus and firewalls to keep bad actors out to using advance analytics, to include big data, cloud security solutions and behavioral analysis. Not only does this minimize the chance of a successful intrusion, but also identifies and controls the intrusion once it does happen, whether from external or internal actors.

We use non-standard analysis, pattern, and trend identification tools across large quantities of data to flag vulnerabilities before security intrusions occur or to spot an intrusion as it is happening. Castalia is a proven company providing Intrusion Detection, Counterintelligence, Cyber and Behavioral Scientists to develop, implement, and maintain technical measures to identify and contain internal and external threats and increase customer cyber defense readiness posture. A lot of companies claim to experts in cyber security; however, Castalia has the past performance and subject matter experts to back it up. Our experienced cyber specialists possess deep understanding of adversaries’ motives, techniques, and tactics to develop an effective cyber posture. Our experts operate in both the Defensive Cyber Operations (DCO) and Offensive Cyber Operations (OCO).


Security is a risk analysis and management activity, therefore, keeping up with FISMA regulations is vital to ensuring system confidentiality, integrity, and availability. This starts with a successful system authorization to operate and proper alignment to the risk management framework (RMF). Castalia utilizes prior system IA experience; existing documentation templates; and support resources and artifacts gained from previous contracts to assist customers with updating cyber security policies, tracking tools, user and operator training and process guides. To ensure compliance with all applicable laws, directives, policies, and directed actions, we employ guidance and direction from the NIST SP 800-37 RMF, NIST 800.53, NIST 800.171, ICD 503, to implement a unified approach to defending the customer systems across multiple network domains.


When implementing an insider risk program, it is necessary to take foundational measures to integrate both technical and non-technical elements for a complete defense. Our insider risk services complement existing technical tools or independently employed. We provide Insider Risk Assessment and Insider Program Design.

Castalia experts provide psychological and counterintelligence knowledge via consultation and training and security mission sets. We assist in building behavioral triggers and models for early and holistic insider threat detection. Such consultation requires extensive knowledge of the insider threat problem, the empirical research conducted, and knowledge of research design and statistical analysis. Our solutions are designed specifically to inform analytical systems calculated to reveal suspected anomalous and illicit Insider conduct.
