After switching from Cisco, Juniper, Astaro and Microsoft network response improved and more control of packet (for me, pfpacket technology is better than packet filter.)
Netgate pfSense is lauded for ease of use and deployment, offering stability and affordability through its open-source model. It excels with VPN features like OpenVPN and IPsec. However, its documentation is insufficient, integration with systems like LDAP is limited, and it demands high Linux expertise. VPN configuration, especially for OpenVPN and WireGuard, is restricted, lacking next-gen firewall features and real-time threat protection.
