runZero vs Zscaler Exposure Management

runZero is an attack surface and exposure management platform for inventorying IT, OT, IoT, cloud, mobile, and remote assets. It combines active scanning, passive traffic sampling, and API integrations to keep the inventory updated. Tracked information can include assets, services, screenshots, software, vulnerabilities, certificates, wireless devices, users, and groups. Reports include layer-2 topology maps and asset risk; alerts can appear in-product or arrive by email or webhook, including Slack. The service can run as hosted SaaS or on-premise using Consoles, distributed Explorers, and a command-line tool. runZero says it operates without agents, authentication, or appliances. Prebuilt integrations span cloud providers, EDRs, MDMs, vulnerability scanners, ITSM systems, and detection platforms, with an API and scripts for custom integrations. Community Edition is free for up to 100 assets, one organization, 10 recurring tasks, and 30 days of data retention. The Platform costs what you agree with the maker. Self-hosting the console requires a Platform license with runZero Care explicitly enabled.
