What it sells: BigID

What Discovery & Classification does
The page describes agentless discovery with hundreds of connectors across the data center, cloud, SaaS and code, with scan depth set per source. Data is read and classified into 2,000+ categories. Models and agents that reach the data, sanctioned or not, are inventoried as assets in their own right.
What DSPM, AI SPM, Agentic SPM does
The page says DSPM began as data risk discovery: find the sensitive data, assess the risk around it. BigID then guides the fix with access governance, activity monitoring, DLP and disposition. It extends all of this to the AI models and agents now reaching the same data.
What Unstructured Data Minimization does
The page says BigID classifies unstructured data at scale and finds duplicates, stale files and out-of-compliance data. Flagged content moves through review to archive or purge, with legal hold checked first.
What Context engineering for AI Agents does[6]
The page says BigID indexes structured and unstructured data and catalogs that metadata behind APIs and MCP. It discovers each agent and what it is approved to do. It also controls which data and metadata every agent can see.
What AgentIQ does[6][9]
The page lets users run a data and AI program from a prompt or an agent. It works inside BigID or from third-party assistants and enterprise agents. Agents that a buyer buys, builds or brings ask the questions, investigate the risk, take the action and keep the work running.
What Data & AI sovereignty does[6]
The page says BigID maps residency, cross-border flows and third-party access from discovery. It applies localization policy and keeps the evidence regulators ask for. The platform can run in-country or fully air-gapped, with zero outbound connectivity.

What it sells: Menlo Security

What Menlo Browser Security Platform does[2][3]
The Menlo Secure Extension delivers Browser DLP and visibility for user interactions with trusted sites and web applications. High-risk browsing activity is automatically routed to the Menlo Cloud for cloud rendering and threat elimination.
What Menlo Browser SSE does[8]
Menlo Browser SSE covers the SWG, CASB, and ZTNA security services found in SASE and SSE. In SASE and SSE, DLP is scattered among the SWG, CASB, and ZTNA services.

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]
