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 Immuta

Immuta sells software that connects to data platforms so customers can register their data and manage access controls on that data. Immuta applies one set of rules to every request, from every human and every agent. Immuta describes a policy engine that governs every human, every agent and every data system on every request they make. Banks, pharmaceutical companies, insurers and government agencies run their data access on Immuta.^[1][3][4]

Immuta states that the right answer to a data request depends on who is asking, what they want and why. Immuta states that an agent cannot sit in a review queue for a week. Immuta states that people should still write the rules and own the exceptions.^[4]

Immuta offers four modules on one policy engine, and a customer can adopt one and add the rest. Immuta lets a rule be written once in plain language, and Immuta compiles the rule into the real controls inside the customer's data infrastructure. Immuta policy answers routine access requests on its own, and people decide the genuine exceptions with the reason attached.^[1][4]

Immuta delegation from a human to an agent can only narrow access, never widen it. Immuta records every access decision as it happens.^[4]

Immuta provides guidance for connecting a data platform and keeping it synced with Immuta. Immuta identification support varies by data source technology and identifier type.^[1][3][4]

About Securiti

Securiti sells the DataAI Command Platform, which provides Data+AI intelligence, controls and orchestration across hybrid multicloud. Securiti says DataAI Command Platform empowers various functions needed by different teams in the enterprise. The DataAI Command Graph automatically captures contextual information for data and AI objects. Securiti says organizations have traditionally been forced to use a variety of disconnected tools to manage security, privacy, governance and compliance for sensitive data, which leads to inconsistent results and added cost and complexity.^[1]

On the security side, Securiti offers a way to secure sensitive data everywhere from hybrid multicloud to SaaS. Securiti discovers cloud-native, shadow and dark data assets across multiple clouds. Securiti classifies sensitive, regulated or custom data using AI and contextual intelligence. Securiti gives insight into users, roles, AI systems and their entitlements to access data systems, files, tables and sensitive data. Securiti enforces policy-based access controls based on attributes to prevent unauthorized data access. Securiti masks sensitive data dynamically based on policies to automate secure data sharing at scale. Securiti improves cloud and SaaS data security posture by prioritizing and remediating misconfigured systems containing sensitive data. Securiti uses 800+ pre-defined rules to assess compliance with security frameworks and regulatory standards.^[7]

On discovery and data minimization, Securiti detects shadow and native data assets across major cloud service providers (AWS, Azure, GCP, OCI) and extracts them into an asset catalog. Securiti discovers hundreds of personal and sensitive data attributes, such as name, address, credit card number, social security number and medical record number, in structured and unstructured databases. Securiti's data discovery comes with 200+ native connectors to connect with on-premises, hybrid and multicloud assets. Securiti includes out-of-the-box detection of data attributes specific to 20+ categories across industries. Securiti imports labels from a Microsoft security center and applies them to files in Box, NFS, SMB and other unstructured data assets. Securiti helps prevent sensitive data sprawl through data streaming systems such as Confluent and Apache Kafka. Securiti identifies and reduces redundant, obsolete and trivial (ROT) data using AI techniques and automated policies. Securiti identifies duplicate or near-duplicate files using AI-powered clustering techniques.^{[7][8][9][10]}

Securiti words Agent Commander as: detect AI risk, protect AI systems, undo AI mistakes. Securiti offers context-aware LLM Firewalls that protect AI systems by monitoring prompts, data retrieval and response. Securiti discovers and catalogs sanctioned and unsanctioned (shadow) AI models and assesses security posture risks. Securiti shows what company data is used by enterprise and SaaS AI applications for model training, tuning and RAG. Securiti discovers and catalogs AI models and agents across all environments, establishes a registry and classifies risks per regulations. Securiti assesses AI systems against NIST AI RMF, EU AI Act and 25+ regulations. Securiti extracts information from complex unstructured files, converts it into AI-ready formats and syncs to vector databases. Securiti transforms raw, unstructured files into data ready for model training and tuning.^[7][11]

On the privacy side, Securiti lets organizations deploy a fully functional privacy center with a frontend, a fully automated backend and integrated privacy regulation intelligence. Securiti collects and maintains an inventory of data assets and data processing activities in a Sensitive Data Catalog. Securiti initiates PIAs and DPIAs and generates Records of Processing Activities (RoPA), such as GDPR Article 30 reports. Securiti securely collects data subject requests, verifies identities, fulfills requests, shares encrypted data securely and keeps all records in one place.
