Firewall Best Practices to Block Ransomware Ransomware continues to plague organizations, with over a third of companies surveyed across 30 countries revealing that they were hit by ransomware in the last year* . Such attacks are ever increasing in complexity and adversaries are getting more efficient at exploiting network and system vulnerabilities, leaving organizations with a significant clean-up bill: a global average of an eye-watering US$1.85M - more than double the cost reported last year.

In this whitepaper, we will discuss how these attacks work, how they can be stopped, and best practices for configuring your firewall and network to give you the best protection possible.
