This white paper outlines best practices for securing networks against ransomware threats. Ransomware is identified as a significant cyber threat, with statistics indicating that it constituted 70% of incident response cases for small businesses and over 90% for midsized organizations in 2025. The paper details the mechanics of ransomware attacks, including the methods used by cybercriminals to infiltrate networks, such as exploiting vulnerabilities and employing identity-based techniques. It emphasizes the importance of minimizing exposure to public internet threats, inspecting network traffic, and identifying threats that penetrate the network. Key recommendations include ensuring network infrastructure is secure by design, consolidating network components, keeping firmware updated, and adopting zero-trust network access (ZTNA) to replace traditional remote access VPNs. The document provides a comprehensive approach to enhancing network security and mitigating the risks associated with ransomware attacks.
