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 | $600M at $12B | Data security | Where does the platform sit in the data stack? |
| Obsidian Security | $85M at $1.1B | Agent identity | What systems and non-human identities are covered? |
| Corma | $60M seed | Defensive cybersecurity AI | What is the buyer and deployment model? |
| Horizon3 | $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.
