ChromeOS vs OPNsense

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.

OPNsense is an open-source firewall and routing platform based on FreeBSD, available for self-hosted, web, and API use. Its stateful firewall supports IPv4 and IPv6 and provides live views of passed and blocked traffic. VPN integrations include IPsec, OpenVPN, Tinc, and WireGuard. CARP supports automatic hardware failover with state synchronization, and inline intrusion prevention uses Suricata with Proofpoint Emerging Threats Open rules. The modular Model View Controller framework supports extensions and API functionality. Authentication options include LDAP, Active Directory, RADIUS, captive portal authentication, and 802.1X through a plugin. Community Edition is free at free under the 2-clause BSD license, and installation is limited to x86-64 architecture. Official setup guides cover AWS images, OVA images, and an Azure Virtual Appliance. Business subscriptions add commercial features and support; listed prices are €149 a year or €399 a year for three years. The project began in 2014 as a fork of pfSense and m0n0wall, with its first official release in January 2015.
