Systems and methods for securing network endpoints

In some embodiments, a network regulator device protects a local network of client systems (e.g. Internet-of-things devices such as smartphones, home appliances, wearables, etc.) against computer security threats. When introduced to the local network, some embodiments of network regulator automatically take over network services from an existing router, and install the network regulator as gateway to the local network. In response to taking over the network services, some embodiments redirect a request by a protected client system to access a remote resource to a security server configured to determine whether granting access to the resource constitutes a computer security threat to the client system.
