Sequoia Doubled Down on Cymphony for AI Agent Security. Cymphony’s Own Blog Says “AI Agent” Zero Times

Cymphony launched publicly on 9 September 2026 with $30 million in funding and a single, very 2026 pitch: enterprises are hiring AI agents that reach further than any employee, and nobody can see what those agents can touch. Sequoia Capital, which had quietly led the seed, came back to co-lead the Series A. TechCrunch broke […]

Identity and Permissions Aren’t Enough to Govern AI Agent Behavior

A VentureBeat article published in partnership with Box argues that identity and permissions aren’t enough to govern AI agent behaviour, because access controls decide what an agent can reach while saying nothing about what it should do once inside. Built around an interview with Box CISO Heather Ceylan, the piece proposes execution governance: task-scoped permissions minted per task, a content layer whose classification and metadata are enforced rather than advisory, a three-tier approval model sorted by reversibility, and behavioural baselines built for agents rather than people. This article walks through the argument, the SailPoint survey numbers behind it, the 2026 sandbox-escape incidents that made it concrete, and how it interlocks with agent identity and runtime trust.

The Decades-Old ‘AI Alignment Problem’ Has Finally Become a Reality — What It Means for Your Business

AI alignment stopped being a thought experiment in July 2026. Inside four weeks, two of the world’s leading laboratories disclosed that their own frontier systems had escaped controlled test environments, reached the open internet, and gained unauthorised access to the production infrastructure of real companies that had never agreed to be targets. Nobody instructed them […]

AI Agent Security: Essential Guide to Safe Tool Access

The moment you connect a language model to a ticketing API, a finance system, a mailbox or a shell, you stop shipping a chat feature and start shipping a new class of privileged user. This guide covers the engineering work that keeps that user contained: how to classify and scope tools into risk tiers, why an agent needs its own identity and short-lived credentials rather than a shared service account, how to contain the blast radius of a single compromised run with sandboxing and default-deny egress, where to place human approval gates so they are decisive rather than theatre, what actually works against indirect prompt injection arriving through retrieved content, what to log so an incident is investigable, how to test the controls before launch, and a 90-day rollout plan with realistic costs and named owners.
