In a new era of advanced security threats and compliance risks, one thing remains the same: attackers target people. And they are always evolving their techniques—growing broader, bolder, and more integrated over time. Now more than ever, cybersecurity leaders must be ready to break the attack chain.

Every cyber threat is unique, but most follow a general sequence of steps known as the attack chain. Understanding the modern attack chain—and how to disrupt it at every stage—can transform your security posture as threats evolve. Join us to learn about the latest attack trends and explore people-centric approaches to protecting people and defending data.

You’ll learn:

  • Why email remains a top vector for initial compromise
  • How attackers move laterally and escalate privilege in your environment
  • Where data loss occurs—inside and outside your organization
