The Center for Internet Security is a nonprofit organization in the computer and network security sector, based in East Greenbush, New York. It maintains widely recognized standards—the CIS Controls and CIS Benchmarks—and coordinates a global community of IT professionals to evolve these practices while offering products and services that help secure IT systems and data. Its offerings include CIS Hardened Images for secure, on-demand cloud environments, and it hosts the Multi-State Information Sharing and Analysis Center (MS-ISAC) and the Elections Infrastructure Information Sharing and Analysis Center (EI-ISAC) to support government and elections-related cybersecurity. Its primary customers include U.S. state, local, tribal, and territorial government entities, elections offices, and IT professionals seeking guidance on cybersecurity. A recent development is the May 1, 2026 publication of the updated CIS IBM AIX 7 Benchmark v1.1.0, reflecting ongoing work to refresh the standards.
