The Department of Homeland Security, specifically the Cybersecurity and Infrastructure Security Agency (CISA), is seeking to procure the TruePlanning Cost Estimating Software through a Limited Source Justification. This software is essential for the Cybersecurity Division's operations, as it supports the design, development, deployment, and maintenance of the National Cybersecurity Protection System (NCPS), which is critical for enhancing cybersecurity across federal agencies. The continued use of TruePlanning is necessary to ensure that staff, already trained on the software, can effectively fulfill their mission obligations.
