The company notes that more than half of the connected devices in an enterprise may be beyond its reach, and are almost certainly beyond its security. Phosphorus describes itself as the industry's only xIoT discovery and remediation platform, emphasizing that securing an organization's Things doesn't mean doubling the work.
