Firewalls
webcentivewebcentive - home
Firewalls: hardware and software that control what traffic may pass between your devices and the internet, blocking connections you did not ask for (CISA). A home router has a basic firewall; a dedicated firewall adds device isolation (IoT/guest networks), intrusion prevention, VPN and better logs. To choose one: match it to your internet speed and number of devices, check how long it gets security updates and whether features need a subscription, and keep the built-in firewall on every computer turned on too (NIST SP 800-41).
