Data security

Data security is the category under the most AI-era pressure in this directory: the same index has to describe DSPM inventories, prompt-level egress controls, and warehouse access enforcement in one list.

This index maps every company whose primary product is finding, protecting, or governing sensitive data: discovery and posture, loss prevention and egress control, data access enforcement, privacy processing mapping, and encryption with confidential computing.

Public mega-cap DLP suites stay off this list. Every entry carries a 2024 to 2026 proof-of-life signal recorded with a source link, and membership is taxonomy from the research pass.

The products here cluster into five shapes. Discovery and posture platforms inventory cloud stores, SaaS, and warehouses, classify content autonomously rather than regex-first, and score who can reach what.

Prevention products follow data in motion and stop the copy, upload, or prompt that would leak it, from browser and endpoint agents to SaaS classifiers with an investigation copilot.

Access enforcement sits in front of warehouses and enforces column-level grants, masking, and purpose controls. Privacy processing platforms instrument applications to map what actually happens to data against what legal promised.

Encryption and confidential-computing platforms keep keys and data-in-use inside hardware enclaves. Eleven of the twelve entries also name an AI-specific surface, from Copilot connectors to prompt policy to AI-readiness checks on training data.

Data protection leads comparing DSPM discovery against prevention-first DLP, privacy counsel who need one shared picture of data flows and promises, platform owners enforcing warehouse-level access, and investors mapping the field by what each product actually enforces.

Included only when a live company has primary category data-security. Cloud posture suites, identity products, and public mega-cap DLP platforms live in their own categories or off this directory.

Inclusion is category-based and verification-gated, not paid placement and not an endorsement of outcomes.

Listings are the full live catalog slice for this primary category, sorted alphabetically by name. This is not a scored quality ranking and there is no paid placement. Aevral is a disclosed house listing under the same rules (live, no pin). See /transparency.
