Preparation Advice for 2026
Hands-On Practice: Use platforms like TryHackMe, HackTheBox (defensive paths), Blue Team Labs Online, and range environments.
Understand the Cloud: Deep, practical knowledge of at least one major cloud provider (AWS, Azure, GCP) is now mandatory.
Follow Trends: Read threat reports from Mandiant, CrowdStrike, Microsoft, and groups like CISA. Follow research on AI security and post-quantum crypto.
Know Your Tools: Be familiar with the core capabilities of major SIEM, SOAR, EDR, and CSPM platforms, even if you're not certified.
Think in Graphs: Modern defense is about connecting entities (users, devices, apps). Understand the value of security data graph analysis.
Communicate Clearly: The ability to translate technical risks into business impact remains the most critical non-technical skill.
