Osterman Research - Reduce Phishing and Ransomware

This Osterman Research whitepaper, sponsored by Avanan, KnowBe4, Mimecast, Trend Micro and others, examines how to reduce phishing and ransomware risks.

Top mitigations include MFA, security awareness training, rapid patching, and cloud backups. Best practices stress addressing root causes, continuous training, and building a security-first culture.
