The Department of Homeland Security (DHS) intends to award a sole source contract to The Centech Group, Inc. for modifications and enhancements to the Integrated Security Management System (ISMS). This procurement aims to secure application development and technical support services, as Centech is uniquely qualified to maintain and enhance the ISMS due to their proprietary source code and extensive development experience. The ISMS is critical for the DHS's operational security, ensuring effective management of security protocols across the department. Interested firms that believe they can meet the requirements are encouraged to express their capabilities to the agency, with inquiries directed to Jessica A. Phillips or Tanya M.
