# Cybersecurity Funding, May–June 2026: The AI Trust Layer

> Security funding concentrated around data governance, agent identity, and the controls required to deploy AI inside enterprise workflows.

Cybersecurity funding in May and June moved toward the **trust layer for enterprise AI**: data access, agent identity, and controls around automated actions. This is a category briefing, not a ranking of security vendors.

## Selected financings

| Company | Amount / mark | Focus | Diligence question |
|---|---:|---|---|
| [Cyera](/2026-cyera-600m-12b-data-security) | $600M at $12B | Data security | Where does the platform sit in the data stack? |
| [Obsidian Security](/2026-obsidian-security-85m-series-d-menlo-ai-agents) | $85M at $1.1B | Agent identity | What systems and non-human identities are covered? |
| [Corma](/2026-corma-60m-seed-sequoia-defensive-cyber-ai) | $60M seed | Defensive cybersecurity AI | What is the buyer and deployment model? |
| [Horizon3](/2026-horizon3-250m-series-e-ai-pentest) | $250M Series E | AI pentesting | Is testing continuous and operationally adopted? |

## What the sample supports

The investable question has shifted from “does the company use AI?” to “what can the AI touch, and how is that access controlled?” Large rounds require a named buyer, a clear security surface, and evidence that the product is embedded in production workflows.

These rounds are not interchangeable: data security, agent identity, and offensive testing have different buyers and budgets. Compare them by problem and deployment, not by headline amount.
