CISA Twitter Privacy Policy and Notice


Cybersecurity & Infrastructure Security Agency (CISA or Agency) will use this Twitter feed for external relations (communications/outreach/public dialogue), to make information and services widely available to the general public, and promote transparency and accountability. CISA External Affairs serves as the executive agent for the CISA Twitter feed and controls who at the Agency has access to make changes to the page. The CISA Twitter feed is not intended to be a means by which CISA and the general public will communicate about individual matters.

CISA will use this Twitter feed to: 1) establish user names and passwords to form profiles and 2) interact on Twitter on official Agency business. Twitter users can choose to follow the CISA Twitter feed, which will provide them with the information DHS delivers on the CISA Twitter feed.

Only CISA provides content through this Twitter feed. Any other Twitter user has the ability to re-“tweet” (i.e., republish) or comment on content provided by CISA through the CISA Twitter feed.
