Sentra

One-liner — Agentless, cloud-native DSPM that discovers and classifies sensitive data across the cloud and adds controls to keep PII out of AI training sets and gen-AI prompts.

What it does — Sentra scans cloud environments (agentless) to find and classify sensitive data, score posture/risk, and detect risky movement (data detection & response). Its current emphasis is data security for AI — keeping training datasets and gen-AI prompts free of PII/restricted data — alongside data access governance (who/what can reach sensitive data). You buy it to get a fast, low-friction map of cloud data risk without deploying agents.

Where it sits in the stack — Primary: dspm; also data-access-governance. Data layer. It controls access to sensitive data (discover/classify/constrain) and reduces leakage risk by keeping sensitive data out of prompts/training. Trust zones: green/yellow cloud data plane feeding AI.

Deployment & architecture — SaaS, agentless/cloud-connector (scans cloud accounts and datastores without installing agents) — a fast, low-touch deployment story. Cloud-first (AWS/Azure/GCP, SaaS). Integrates with DLP, IAM, and SIEM/workflow tooling. Direct architectural analog to cyera.

Positioning & differentiators — Sentra and cyera are the two prominent Israeli, ex-Unit 8200, agentless cloud-native DSPM challengers; Sentra is the smaller/earlier-stage of the pair and leans hard into the “secure data for AI adoption” framing. Versus bigid (broad governance/privacy, on-prem heavy) Sentra is leaner and cloud-only. Versus microsoft-purview it spans beyond the Microsoft estate and stands up faster. Differentiators it claims: classification accuracy and agentless DSPM + DDR (data detection & response) for movement, not just static posture.

Ownership, funding & M&A — Independent, privately held. Founded 2021; HQ Tel Aviv with a New York office. Founders: Yoav Regev (CEO, ex-Head of Cyber Dept, Unit 8200), Asaf Kochan (President, former Unit 8200 commander), Ron Reiter (CTO), Yair Cohen (VP Product). Funding: $50M Series B (Apr 2025) led by Key1 Capital (Bessemer, Zeev Ventures, Standard Investments, Munich Re Ventures participating), bringing total to >$100M (prior $30M Series A). No acquisition; no seed M&A flag. Ownership confidence: high.

CTO / hedge-fund lens — Day-1 for a cloud-heavy fund that wants fast, agentless data discovery specifically to de-risk AI adoption (clean training data / prompt hygiene). Lighter and earlier-stage than cyera; a reasonable shortlist entry if you want a focused cloud DSPM without the enterprise heft (or price tag) of the leaders. SR 11-7: supports AI-governance/data-lineage evidence indirectly. Caveat: smaller vendor (concentration/longevity risk), SaaS-only, cloud-first — less relevant for on-prem-heavy estates.

Competitors / alternatives — cyera, bigid, securiti, concentric-ai, microsoft-purview, Varonis.
