Overview of this book

OPNsense is one of the most powerful open source firewalls and routing platforms available. With OPNsense, you can now protect networks using features that were only previously available to closed source commercial firewalls. This book is a practical guide to building a comprehensive network defense strategy using OPNsense. You’ll start with the basics, understanding how to install, configure, and protect network resources using native features and additional OPNsense plugins. Next, you’ll explore real-world examples to gain in-depth knowledge of firewalls and network defense. You’ll then focus on boosting your network defense, preventing cyber threats, and improving your knowledge of firewalling using this open source security platform. By the end of this OPNsense book, you’ll be able to install, configure, and manage the OPNsense firewall by making the most of its features.

Summary

In this chapter, you were introduced to OPNsense, its project history, versions, and the improvements made by pfSense and m0n0wall. I also shared a little bit of my history with you and why I decided to use it, with some examples. We learned about FreeBSD and what it is and is not, and about its hardened fork, HardenedBSD. We explored the OPNsense core features and typical deployments, with some examples of how you can deploy them in your network environment. Finally, we dived into support options and how to use each of them. Now that we know how OPNsense works, we can find help if needed, which versions are available, and the most common scenarios to deploy it. We will now move on to the following chapters, which will help you better understand some of the concepts discussed in this chapter more practically. In the next chapter, we will see how to install OPNsense and explore some of its features!
