About

Guardio is developing tools and products to combat modern web- and cloud-based threats. Guardio's infrastructure enables real-time updates to block signatures, rules, and heuristics. Guardio utilizes a mixture of real-time and bulk data pipelines in conjunction with dynamic heuristics to provide relevant information when performing analysis. Guardio routinely maps, stores, and indexes the entirety of the Chrome Extension ecosystem. This allows for extensive coverage of malicious extensions. Extensive portions of the visible internet are constantly being probed and mapped. Metadata and fingerprints (such as WHOIS, DNS records, hosting providers, etc.) are constantly gathered and factored into Guardio's decision-making engine. Some methods used by Guardio include client-side deep-learning models in order to detect logos in fraudulent websites and provide immediate mitigation without compromising privacy, bandwidth, or security. Guardio's algorithms and heuristics continuously sift through large amounts of data, looking for anomalies and signs of malicious activity. By cross-referencing information across the many sources available, Guardio uncovers and flags the business models, modus operandi, and infrastructure of criminal actors.
