Torus is a decentralized, browser-based firewall extension developed by OpenAVN (DefenseArk). It operates as a lightweight browser extension that runs in the background during browsing sessions to filter out digital threats in real time. Torus connects to OpenAVN's global digital threat detection network, which collects and analyzes large volumes of malware and threat data daily. This network feeds into machine learning models that power Torus's threat detection capabilities. The extension protects users against adware, phishing attempts, malicious links, and browser-delivered malware. It also blocks cross-site tracking by advertisers and third-party trackers. Torus is available at no cost when paired with a BrightScan subscription. It is compatible with Chrome, Firefox, Safari, Internet Explorer, and Edge. OpenAVN states that it does not sell user data to third parties; data collected is limited to novel threat intelligence used to improve detection models.
