HiddenLayer and Cohere partner to secure enterprise AI agents against prompt injection and data leakage

HiddenLayer, an AI security company, has partnered with Cohere to enable enterprises to deploy agentic AI at scale with built-in protection against AI-native threats. The collaboration combines Cohere's North platform with HiddenLayer's AI Security Platform to address risks including prompt injection, data leakage and malicious tool use. The partnership allows organisations to deploy AI agents that connect to enterprise systems whilst defending against attacks that traditional security tools cannot address. HiddenLayer tested the solution internally before deployment, demonstrating practical security for production environments. Key capabilities include detecting prompt injection and model attacks at runtime, reducing data leakage risks, and providing audit-ready visibility for compliance. The companies will host a webinar on 30th June to discuss secure enterprise AI deployment.

HiddenLayer launches agentic runtime security to protect autonomous AI agents from breaches

HiddenLayer has launched new AI Runtime Security capabilities designed to protect autonomous AI agents as enterprises increasingly adopt agentic AI systems. The update introduces three core features: Agentic Runtime Visibility, Agentic Investigation & Threat Hunting, and Agentic Detection & Enforcement. According to HiddenLayer's 2026 AI Threat Landscape Report, one in eight AI breaches are linked to agentic systems. The new capabilities enable security teams to monitor agent behaviour in real-time, detect threats including prompt injection and data exfiltration, and enforce adaptive security policies. The solution integrates directly into agent gateways and execution frameworks, allowing phased deployment without application rewrites. CEO Chris Sestito noted that compromised AI agents can access systems and move data within seconds, making real-time visibility and control essential for enterprise security.
