Guardian Exposure Map is a network visibility and risk assessment tool that provides organizations with real-time insight into connected systems and potential security exposures. The tool is installed on a single device and performs automated network analysis to identify assets, map network topology, and highlight security risks. The tool analyzes network traffic to discover active devices on the network, probes open ports to determine running services, software versions, and operating system details. It uses traceroute techniques to map routing paths, measure response timing patterns, and analyze TTL values to infer network hops and device placement, creating a visual representation of network topology. Guardian Exposure Map evaluates collected data including device configurations, known vulnerabilities, and network topology to identify security risks. Identified risks are ranked by severity and potential impact. The tool detects vulnerabilities such as open ports and outdated operating systems, verifies device inventories, and uncovers unknown or unauthorized devices on the network. The tool supports Windows, macOS, Linux, and mobile platforms. It is designed as a lightweight solution that can be deployed quickly without requiring extensive infrastructure changes.
