Security outcomes rarely hinge on a single alert or control failure. Modern adversaries chain trusted identities, misconfigurations, third-party access, and unmonitored control planes into intrusions that spread across domains and lead to costly downtime and disruption.

The Lessons from the Front Lines guide is designed for this reality. Aligned to the top six adversary themes noted in the CrowdStrike 2026 Global Threat Report — AI use and targeting, cross-domain tradecraft, edge device exploitation, supply chain compromise, objective-driven zero-day selection, and cloud trust abuse — this guide provides organizations a practical playbook for prevention and readiness.

Key takeaways:

•  Frontline Intelligence: Direct insights from CrowdStrike’s incident responders on how these modern intrusions unfold
• Prevention Strategies: Playbooks to defend against the top adversary tactics shaping today’s threat landscape
• Response Guidance: Battle-tested frameworks to contain and evict threats when prevention falls short
