Automated Indicator Sharing (AIS) Documentation


Automated Indicator Sharing (AIS), a Cybersecurity and Infrastructure Security Agency (CISA) capability, enables the real-time exchange of machine-readable cyber threat indicators and defensive measures to help protect participants of the AIS community and ultimately reduce the prevalence of cyberattacks.  The AIS community includes private sector entities; federal departments and agencies; state, local, tribal, and territorial (SLTT) governments; information sharing and analysis centers (ISACs) and information sharing and analysis organizations (ISAOs); and foreign partners and companies. AIS is offered at no cost to participants as part of CISA’s mission to work with our public and private sector partners to identify and help mitigate cyber threats through information sharing and provide technical assistance, upon request, that helps prevent, detect, and respond to incidents.

The AIS ecosystem empowers participants to share cyber threat indicators and defensive measures, such as information about attempted adversary compromises as they are being observed, to help protect other participants of the AIS community and ultimately limit the adversary’s use of an attack method. The more you share, the more everyone becomes informed, and the more we all prevent further damage from vicious cyber-attacks together!
