- Defensive Cyber Operations (DCO) programs are key elements of the DCO Maneuver Baseline infrastructure, platform, and tools. The employment of defensive capabilities achieves the following objectives: deter, destroy and defeat cyberspace threats; gain time; economy of force; control key terrain; protect tasked critical assets and infrastructure; and develop intelligence. DCO consists of software and platform programs which are key elements of the DCO Maneuver Baseline infrastructure, platform, and tools. DCO supports the Army Cyber Command (ARCYBER), Information Warfare Operations Center (IWOC), Army Forces Command (FORSCOM), Global Cyber Centers (GCC), Regional Cyber Centers (RCCs), Cyber Warfare Battalion (CWB), Multi-Domain Task Force (MDTF), Cyber Protection Brigade (CPB), and Cyber Protection Teams (CPTs) in the Active Army, Army National Guard, and the Army Reserve. Fiscal Year (FY) 2027 funding in the amount of $92.786 million supports Cyber Analytics (CA), DCO Tools Suite, User Activity Monitoring (UAM), Forensics and Malware Analysis (F&MA), DCO Development Environment (DCODE), Garrison DCO Platform (GDP), and Deployable DCO System (DDS) capabilities. Funding will be executed by Program Executive Office - Intelligence, Electronic Warfare and Sensors (CPE IEW&S). - ARCYBER Rapid Cyber Prototyping (RCP) provides software-based capabilities that can quickly respond to emerging cyber threats and keep up with threat technology, while supporting multi-Domain operations. ARCYBER identifies potential development and prototyping efforts via Cyber Needs Forms (CNFs) based on operational feedback, changes in the operational information environment and/or trends of adversarial activity, which drive concept of operation (CONOP) and Tactics Techniques and Procedures (TTPs) modifications. These are separate and distinct from DCO programmed efforts already funded or budgeted for by Project Manager (PM) DCO and are used to rapidly address a network threat/vulnerability. FY 2027 funding in the amount of $1.309 million will be executed by ARCYBER.

FY2025 accomplishments Prior to BA8 Pilot program, this capability was funded with RDTE funding (PE 0605041A EV5). FY 2025 funding supports continuous ARCYBER rapid cyber prototyping efforts on identifying and assessing novel non-program-of-record defensive cyberspace operations and big data platform-related solutions for automated vulnerability and anomaly detection, network monitoring and visualization, and advanced modeling and predictive analytics. ARCYBER will continue to mature its Cyber Fusion Innovation Center (CFIC) by increasing industry and academia outreach to drive ARCYBER, industry, and academia collaboration on state-of-the-art approaches to cyber operations problem-sets.
