OPNsense accepts the challenge and meets these criteria in different ways. A firewall offers the highest level of protection if its functions are known, its operation is simple, and it is ideally positioned in the surrounding infrastructure.
They protect against known and new threats to computers and networks. Firewalls are a component of the security concept. Even home networks, washing machines, and smartwatches are threatened and require a secure environment. No network is too insignificant to be spared by an attacker. And OPNsense is a top player when it comes to intrusion detection, application control, web filtering, and anti-virus. Even the open-source domain is moving towards Next-Generation Firewalls. Simple packet filters are becoming a thing of the past. Available Now! - 4th Edition! The complete 4th Edition of Practical OPNsense® by Markus Stubbig
