Panaseer's continuous control monitoring platform is a powerful tool that can monitor and monitor all aspects of your organization. It provides trusted, automated insight into the organisation's security and risk posture. We create an inventory of all entities in your organization (devices and apps, people, accounts, and databases). The inventory identifies assets that are missing from different sources and identifies security risks. The platform provides metrics and measures that will help you understand your compliance and security status at all levels. The platform can ingest data from any source, cloud or on-premises. Data can be accessed across security, IT, and business domains using out-of-the box data connectors. It uses entity resolution to clean and normalise, aggregate and de-duplicate this data. This creates a continuous feed with unified assets and controls insights across devices and applications, people, database and accounts.
