Expanded Highly Adaptive Cybersecurity Services Now Available on GSA’s IT Schedule 70

New HACS SIN Provides Agencies with Solutions to Protect Assets & Respond to Incidents

WASHINGTON, D.C - The U.S. General Services Administration (GSA) has modernized the Highly Adaptive Cybersecurity Services (HACS) Special Item Number (SIN) to include expanded cybersecurity services. The modernized HACS SIN gives federal agencies easier access to a complete solution of cybersecurity services designed to meet the government's requirements to protect high value assets (HVA) and mission-critical systems.

"The cybersecurity market has rapidly evolved since the initial creation of the HACS offerings just two and a half years ago, and GSA is responding to this evolution by including key cybersecurity services that were missing from the original SIN," said GSA Acting Assistant Commissioner Bill Zielinski. "The restructured HACS solution on IT Schedule 70 will provide federal agencies with easier access to services and solutions to protect large complex network and data systems, including HVAs that hold sensitive information critical to national and economic security."

In collaboration with the Office of Management and Budget (OMB) and the Department of Homeland Security (DHS), GSA identified several key cybersecurity services that should be added to enhance GSA's offering.

The restructuring supports actions outlined in the "Report to the President on Federal IT Modernization [PDF]" and OMB Memo 19-03 "Strengthening the Cybersecurity of Federal Agencies by enhancing the High Value Asset Program". Agencies using the HACS SIN also meet the guidance outlined in OMB Memo 17-12 "Preparing for and Responding to a Breach of Personal Identifiable Information" which recommends the use of GSA's HACS SIN to buy services that address these concerns.

GSA's enhanced HACS SIN 132-45 on IT Schedule 70 with service sub-categories is a more broadly defined SIN that does not have to be updated as the cybersecurity market evolves, and it aligns with the needs of customer agencies to purchase total solutions.

The SIN is open to industry partners for on-ramping and for Department of Defense and civilian federal agencies as well as state and local government to begin purchasing cybersecurity services. All current IT Schedule 70 Program suppliers that offer cybersecurity services are welcome, but not required, to move their solutions onto the new SIN.
