Eight security vendors shipped agent runtime governance on the same Monday.

Cyera, KnowBe4, Sweet Security, Varonis, Zero Networks, Cato Networks, Cribl and Prophet Security all announced agent-focused controls August 3 at Black Hat, plus Acalvio and Cycode days prior. The convergence is unusually tight on mechanism, not just theme: nearly all ship prompt-injection detection, unauthorized-tool-call blocking, and session-level rather than request-level evaluation. Agent runtime governance went from a startup pitch to a table-stakes incumbent feature in one announcement cycle, which badly compresses the window for seed-stage companies selling it standalone.
