ChromeOS vs pfSense

ChromeOS is Google’s operating system and the core software for Chromebooks, Chromeboxes, Chromebases, and Chromebits. ChromeOS Flex can install on certified existing PCs and Macs, including through USB or remote cloud deployment, and is described as available at no cost. Google presents ChromeOS for business, education, frontline, healthcare, manufacturing, retail, kiosk, and signage use. The Admin console manages devices, apps, extensions, updates, and Google Workspace. Built-in protections include verified boot, a read-only operating system, blocked executable files, encryption, and sandboxing; administrators can remotely wipe devices and require re-enrollment. Supported apps include Zoom, Slack, Google Workspace, Microsoft Office 365, and Teams, with Citrix and VMware for virtualized Windows and legacy apps. Updates arrive every four weeks, and devices receive ten years from platform release. Managed Google Play apps are unavailable on ChromeOS Flex.

pfSense is a free, open-source firewall and router distribution based on FreeBSD, managed through a web interface. Its firewall uses stateful packet inspection and can block traffic based on policy matches. Routing features include policy-based routing, static routes, and concurrent IPv4 and IPv6 support. Security options include IDS/IPS, Snort packet analysis, Suricata rules, IP block lists, and application detection. It supports IPsec, OpenVPN, and WireGuard for site-to-site and remote-access VPNs. The software can run on selected hardware, virtual machines, and cloud instances, and is available in the Azure and AWS Marketplaces, including their US GovCloud regions. The Community Edition is free and open source. pfSense Plus on third-party hardware starts at $129 a year; on Netgate appliances it starts at $189, paid once, with the software included at no charge with an appliance. The USB installer overwrites the entire hard drive and does not support dual booting.
