Cyera buys Oasis Security for $1B to secure AI agents

Snowflake launched Cortex AI Gateway, a centralized control layer for governing how AI agents access enterprise data and tools, alongside security integrations with 1Password, Aembit, Linx Security, SailPoint, and Saviynt. The platform addresses a fundamental security gap: traditional enterprise security assumes humans are the actors, but AI agents operating at machine speed can exploit permission gaps and amplify existing risks. Snowflake positions itself as the control plane that decides what agents can do with enterprise data, rather than allowing each vendor to build closed ecosystems.

Beijing-based AI startup Moonshot has trained its Kimi K3 model, the world's largest open-source model with 2.8 trillion parameters, using Nvidia's advanced Blackwell chips despite U.S. export restrictions on such technology to Chinese firms. The company is now seeking additional Blackwell chips to develop Kimi K4, a significantly larger successor model. The situation highlights the tension between U.S. chip export controls and Chinese AI development capabilities.

Microsoft unveiled MAI-Cyber-1-Flash, a custom-built AI security model, and Project Perception, an agentic defense platform designed to automate vulnerability detection and remediation. The system scores 96% on the CyberGym benchmark while cutting costs roughly in half compared to Microsoft's current production setup. The architecture routes 90% of security tasks to the smaller, cheaper model and escalates the remaining 10% to OpenAI's GPT-5.4, reflecting Microsoft's strategy to compete on cost efficiency rather than raw model size.

At VB Transform 2026, SAP's Max McPhee outlined how enterprises can move beyond chatbots to autonomous AI agents by grounding them in company-specific context through knowledge graphs and governance controls. The key difference between assistants and true agents lies in providing enterprise context rather than relying on general knowledge, combined with identity and permission controls that prevent agents from circumventing access restrictions. SAP's recent acquisitions of LeanIX and Signavio, plus investment in n8n, are designed to help agents navigate complex, multi-system enterprise landscapes where SAP represents only a portion of the technology stack.
