The Cipher Brief is a national security media and analysis organization that brings together leaders from government and the private sector to examine major global threats and explore ways to address them. Its flagship event, the annual Cipher Brief Threat Conference, is an invitation-only gathering for professionals working in national security. The 2026 conference is scheduled for October 25–28 at The Cloister at Sea Island, Georgia.

The conference features expert-led conversations, practical exercises, panels, speed roundtables, breakout events, and fireside chats. Topics include China, Taiwan, Ukraine, Russia, quantum technology, artificial intelligence and machine learning, cyber threats, emerging technology, espionage, alliances, digital transformation, and foreign malign influence. Sessions are designed to encourage effective collaboration between public- and private-sector participants, while helping attendees build connections across the national security community.

The Cipher Brief also offers sponsorship opportunities for companies seeking to participate in high-level, nonpartisan discussions and engage with its experts and serving security decision-makers. Through its website, the organization provides conference information and offers updates and briefings by subscription.
