What the company sells

Concentric AI sells an AI and data security governance platform that discovers, governs and protects data at rest, in motion and used by AI. Concentric AI says it helps organizations accelerate AI initiatives with confidence by discovering, understanding, governing and protecting enterprise data. Concentric AI describes one end-to-end platform to secure data at rest, in motion and across the AI applications that users interact with.

Concentric AI says the platform uses patented language models to understand the context, ownership, exposure and business value of data. Semantic Intelligence discovers, categorizes and classifies data across environments, monitors data risk with autonomous remediation, tracks data lineage across its life cycle and maintains visibility into Microsoft Copilot permissions and usage. Semantic DLP gives visibility and control to keep confidential data out of AI tools. Semantic DLP identifies the riskiest users and applications, prevents sensitive data from being shared with AI tools and tracks prompts, responses and policy violations.

Concentric AI says DSPM is the practice of discovering sensitive data, determining where it resides, identifying who can access it, assessing associated risk and continuously monitoring the organization's data security posture. Concentric AI discovers structured and unstructured data across cloud, on-premises, SaaS applications, databases, file systems and AI environments. Concentric AI scans the full dataset rather than relying on sampling. Concentric AI delivers insights into data sensitivity, identity and activity so that teams can make access decisions that reduce sensitive data exposure. Concentric AI complements existing IAM, DLP, Microsoft Purview and other security investments by adding deeper context about the data being accessed.

Concentric AI monitors activities including accessing, creating, modifying, downloading, copying, moving, sharing and deleting data. Concentric AI can support response actions such as blocking downloads, preventing unauthorized sharing and revoking access. Concentric AI supports classification and labeling, moving data, deleting or archiving unnecessary data, managing access and permissions, and blocking or masking sensitive data. Concentric AI says remediation can be configured for different levels of automation.

AI DLP protects sensitive data as it is shared with AI applications. Concentric AI says policies can warn, block or mask sensitive content based on the data involved and the context of the interaction. Concentric AI discovers the AI tools users are accessing across the environment, including sanctioned applications, unsanctioned tools and emerging applications. Concentric AI shows which departments share sensitive data with which AI applications and the types of information flowing into them. AI Data Guardrails provides a governance framework for understanding AI and data activity, defining contextual policies and establishing boundaries for how AI uses sensitive data. Concentric AI lets teams define guardrails based on AI application, data type, user, department, user group or other relevant context.

On deployment, Concentric AI says Semantic Intelligence is 100% SaaS-based, with no appliances to install or configure. Semantic Intelligence connects to cloud-based data repositories via API and to on-prem repositories using a virtual proxy. Semantic Intelligence does not require agents. Semantic DLP is installed as a browser extension and can recognize and protect data across any AI tool accessed through the browser. Semantic Intelligence is priced by the amount of data scanned, and Semantic DLP is priced by the number of users. Concentric AI says its platform provides visibility and control across SaaS applications, cloud environments and on-premises repositories.^{[1][3][7][8][9][10][11][12][13][14]}
