State Secrets

In this episode of State Secrets, former CIA Senior Operations Officer Sean Wiswesser examines the evolution of Russian intelligence - from Soviet-era tradecraft to modern hybrid warfare. He unpacks Moscow’s strategic mindset, its transactional relationships with partners like Iran, and its enduring focus on weakening democratic systems. With insights drawn from decades in the field, Wiswesser explains what most people misunderstand about Russia - and why that matters now more than ever.

What the Experts Say

“I am struck by how comprehensive and thoughtful The Cipher Brief’s Open Source Report is. It is just as good as the President’s Daily Brief, having spent a decade reading the PDB. And it’s unclassified, too! I'm proud to be part of the network of experts at The Cipher Brief, which provides superb geopolitical advice and intelligence insights.”

Admiral James Stavridis (Ret.)

“The Cipher Brief Threat Conference is the nation’s premier gathering of current and former intelligence and security experts. If you want to know what’s really going on—or hear some spirited debate about what’s about to happen—in our complex world, this is the place to be!"

Admiral Sandy Winnefeld (Ret.), Former Vice Chairman, Joint Chiefs of Staff

The Cipher Brief has become the preeminent information platform for the national security community. I read it, I contribute to it, and I recommend it to military, civilian, and industry partners seeking the most up-to-date and expert analysis of the major issues facing the government, business, and others committed to the security of the nation.

Lieutenant General (Ret.) Guy C. Swann III

"The Cipher Brief is my daily 'must read' for insightful coverage and analysis of national security events. I find the Open Source Report to be a key tool in assessing global geopolitical risk, and illuminating national security challenges in just the right amount of depth. It's the perfect balance. I can read it quickly, but step away feeling I have a solid grasp of the issues and implications. Thanks to the brilliant Cipher Brief Team! "
