Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems and information. Our cybersecurity risk management program includes a cybersecurity incident response plan (“IRP”). The purpose of the IRP is to provide a structured and systematic incident response process for all Information Security Incidents that affect any of our or our subsidiaries’ information technology systems, network, or data, including data of ours and our subsidiaries held, or IT services provided by, third-party vendors or other service providers. We developed and maintain our program as required by applicable laws and regulations, including without limitation the Cybersecurity Maturity Model Certification (CMMC) and 17 CFR Part 229. On September 10, 2025, the Department of War (DoW) published its final Cybersecurity Maturity Model Certification (CMMC) rule in the Federal Register, effective November 10, 2025, officially launching a three-year phased rollout of cybersecurity requirements across DoW contracts. The rule, implemented through the Defense Federal Acquisition Regulation Supplement (DFARS) under Title 48 CFR, establishes mandatory cybersecurity standards for all contractors and subcontractors. Certification is required to handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI) and to bid on new contracts. CMMC 2.0, announced July 17, 2021, streamlined requirements to three levels: •Level 1: Self-attestation allowed. •Levels 2 & 3: Third-party assessments required. Failure to achieve CMMC certification will prevent bidding on new or follow-on contracts, creating significant contract risk. Compliance efforts will require substantial and ongoing investment, increasing cost pressures. Additionally, non-compliant subcontractors may jeopardize overall eligibility for DoW work. Collectively, these factors could negatively impact revenue, operating margins, and cash flow. As of July 24, 2025, Kratos has received Final CMMC Level 2 (C3PAO) Certification. Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across our global enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas. We have designated our Chief Information Officer (CIO) to implement and maintain the IRP. Our CIO has over 20 years of experience in the field of information technology including cybersecurity and is responsible for the management of our cybersecurity and data privacy program. Among other information security duties, the CIO is responsible for: •implementing the IRP, •identifying and managing an incident response team (“IRT”) principally responsible for managing (1) our cybersecurity risk assessment processes, (2) our security controls, and (3) our response to cybersecurity incidents, •coordinating IRT activities, including developing, maintaining, and following appropriate procedures to respond to, appropriately escalate, make decisions regarding, and document identified cybersecurity incidents, •conducting post-incident reviews to gather feedback on identified cybersecurity incident response procedures and address any identified gaps in security measures, •providing training and conducting periodic exercises to promote employee and stakeholder preparedness and awareness of the IRP, and •reviewing the IRP at least annually, or whenever there is a material change in our business practices that may reasonably affect its cybersecurity incident response procedures. Our cybersecurity risk management program includes: •risk assessments designed to help identify material cybersecurity risks to our critical systems, information, products, services, and our broader enterprise IT environment including risks associated with ransomware; •the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls; •cybersecurity awareness training of our employees, incident response personnel, and senior management; •a cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents; and •a third-party risk management process for service providers, suppliers, and vendors. We have developed processes to identify and oversee risks from cybersecurity threats associated with our third-party service providers, which includes the information security team assisting with and assessing cybersecurity robustness during vendor onboarding as well as risk-based monitoring of vendors on an ongoing basis. We have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition.
