The General Services Administration announced April 2 that it had restructured its Highly Adaptive Cybersecurity Services Special Item Number to include a greater spectrum of cyber services, to keep pace with changing cybersecurity needs.

The HACS SIN is part of the IT Schedule 70 acquisition vehicle and enables federal agencies to purchase proactive and reactive cybersecurity services.

“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 in a news release.

“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 [high value assets] that hold sensitive information critical to national and economic security.”

According to a GSA spokesperson, the restructuring takes the four original SINs under the HACS contract and consolidates them into a single SIN with five subcategories: High Value Asset Assessments, Risk and Vulnerability Assessment, Cyber Hunt, Incident Response and Penetration Testing.

High Value Asset Assessment was not initially included as its own SIN but was created as a new subcategory for the restructuring.

At the time pf publication, 210 contractors were listed on the HACS SIN.
