About BigID

BigID sells one platform for security controls, compliance and privacy automation, and AI governance. BigID says it detects sensitive data, AI and identities across an organization's estate, protects them, and governs who and what can reach them.^[1][5]

BigID says security, privacy and AI teams usually work from separate tools and separate answers. BigID gives those teams one catalog and one graph. BigID builds one catalog across cloud, SaaS, on-prem and mainframe, and classifies it automatically. BigID governs AI models and the data they run on together, so policy becomes a control and every control leaves evidence behind.^[5][16]

On the data security side, BigID includes access governance, activity monitoring, loss prevention, lifecycle and privacy management natively within its DSPM offering. BigID discovers sensitive data in every store, classifies it, and flags overshared files, stale access, and unmanaged models and agents. BigID classification uses 2,000+ pretrained classifiers and prompt based LLM classification for structured and unstructured data. BigID reads permissions metadata at the source and reviews it against policy, surfacing the conflicts for attestation. BigID discovers agents, sanctioned and unsanctioned, and shows the data each one reaches through the identity it runs under.^{[3][6][8][13][17]}

Agents reach BigID through an RBAC-controlled MCP, approved agents are recognized by identity, and each one is limited to the context data its role and stated intent call for.^[6][18]

On deployment, BigID offers multi-tenant SaaS with full data segregation options, data ringfenced inside any of 30+ countries, and single tenant full isolation set as a deployment flag on the same product. BigID says an air-gapped deployment delivers the same discovery, classification, remediation, and AI governance as BigID SaaS. In a sealed, air-gapped environment, BigID runs with zero outbound connectivity and no phone-home telemetry. BigID for Federal is described as secure data for federal programs, on a platform that is FedRAMP High authorized.^{[6][8][10][16][19]}

On privacy, BigID privacy requests arrive through a branded portal, forms, APIs or internal teams, identities are verified, and each request is routed by type, jurisdiction and brand. BigID lifecycle management covers ROT detection, sandboxed review before anything moves, and soft and hard delete, with legal hold and downstream impact checked first.^[8][13][20]

BigID pushes classification and labeling into Microsoft Purview.^{[2][5][6][7][8][9][10][11][12][13][19][20][21][22]}

About Concentric AI

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.^[3][7]

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.^{[3][7][8][10][12][13][14]}

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.^[8][9]

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.^[10][11]

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.^[9][12][13]

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]}

About Sentra

Sentra sells a platform that finds sensitive datasets across cloud, SaaS, on-prem and AI services and shows which people and AI agents can reach them. Sentra says it finds sensitive data, maps which people and AI agents can access it, and removes the access that should not be there, all inside the customer's environment. The company states its aim as knowing what sensitive data every AI agent can access, understanding what each agent can do with that data, and continuously enforcing the right controls. Sentra says one platform runs inside the customer's environment and powers every module.^{[3][4][8][10]}

Sentra keeps a continuously updated inventory of sensitive data across cloud, SaaS, warehouses, collaboration tools and on-prem stores, including the knowledge bases behind copilots and agents. Sentra describes its discovery as agentless across cloud, SaaS, data platforms, file shares and on-prem. Sentra says it has 250+ built-in classifiers and 130+ file formats, with over 98% accuracy and under 1% false positives. Sentra says it can classify the knowledge bases, training sets and data stores behind Bedrock, SageMaker, Azure OpenAI, Vertex AI, Databricks, Snowflake Cortex, Microsoft 365 Copilot and Gemini for Workspace.^[9][14]

Sentra says it continuously removes shadow, stale and toxic data from AI pipelines, RAG indexes and knowledge bases. Sentra masks, redacts or tokenizes PII, regulated data and toxic structured content at the source before it feeds any AI pipeline. Sentra aims to make entitlements follow the data so that every user and AI agent sees only what they are entitled to, across the data plane and the AI plane. Sentra Shadow AI DLP combines Shadow AI Discovery with browser-based data protection to discover AI usage and prevent sensitive data from being shared with AI. Sentra points to Microsoft Copilot, ChatGPT, Claude, Gemini and hundreds of other AI tools as part of everyday work. Sentra can block, warn, or require user justification before sensitive data is shared with AI.^[3][4]

Sentra fixes clear-cut exposures, like a confidential file shared publicly, automatically and sends ambiguous cases to the data owner. Sentra says a policy can disable public links, remove external users, revoke excess permissions, quarantine files or delete redundant copies. Sentra routes judgment calls to the data owner in Slack, Teams, Jira or ServiceNow and tracks every issue to closure. Sentra continuously checks where regulated data lives, who and what can reach it, and whether AI uses it within policy. Sentra's continuous regulatory coverage names GDPR, HIPAA, PCI DSS, CCPA, SOC 2, ISO 27001, EU AI Act, NIST AI RMF and emerging AI frameworks. Sentra says audit trails exist for every dataset, classification decision, access event and enforcement action.^[3][5][16]

Sentra says discovery, classification and analysis run inside the customer's environment, which keeps Sentra out of the customer's data-transfer scope. Sentra connects to existing security, cloud and AI stacks so governance follows data everywhere it goes. Sentra's Jira integration creates, updates and assigns tickets when an issue is created, and its ServiceNow integration does the same. Sentra's Slack integration sends issues and notifications to a channel of the customer's choice, and its Microsoft Teams integration does the same. Sentra's PagerDuty integration triggers incidents from incoming issues. Sentra's Splunk integration sends issues to Splunk SIEM, and its Microsoft Sentinel integration sends issues and notifications to Microsoft Sentinel. Sentra's Wiz integration enriches the Wiz Security Graph with Sentra's data findings.^[3][11][16]

For financial organizations, Sentra says it can discover and classify high-risk data across cloud environments. Sentra says it can ensure compliance with PCI DSS, GDPR and CCPA. For healthcare, Sentra says it discovers and classifies sensitive PHI across cloud environments and supports automated reporting for HIPAA and HITRUST. For retail, Sentra says it secures e-commerce systems, ensures compliance and mitigates supply chain risks. Sentra says retailers can streamline adherence to PCI-DSS, GDPR and other frameworks and detect violations like exposed credit card or customer data.^[5][6][7]

Sentra says its licences are generally based on the volume of data stored across IaaS, PaaS, DBaaS, SaaS and on-premises environments. Sentra says it gives quotes tailored to scale, stack and organization priorities. Sentra undergoes an annual SOC 2 Type 2 audit against the AICPA Trust Services Criteria, and the report is available on request under NDA. The Standards Institution of Israel certifies that Sentra operates an Information Security Management System conforming to ISO/IEC 27001:2022, issued May 12, 2025 and valid through May 15, 2028. Sentra states penetration testing every six months and says customer data is deleted within 24 hours of offboarding.^{[2][3][5][6][7][8][9][10][11][16]}
