In this chapter, we have covered how to configure and use the different Untangle Blockers (Virus Blocker, Spam Blocker, Phish Blocker, and Ad Blocker) to protect your network. Each application was covered in full detail starting from how it works, how to configure it and review the scan history, and if it has any common issues and how to solve them.

In the next chapter, we will cover how to protect against Denial of Service attacks using the Untangle shield, protecting our network from malicious traffic using Untangle Intrusion prevention, and limiting access from the Internet to your internal resources using the Untangle Firewall application.
