Salt Code: securing ai-generated code in development.

Salt Code: securing ai-generated code in development. Summary. Salt Security has launched Salt Code, a new solution designed to enforce security policies within AI coding assistants. This tool aims to ensure that all AI-generated code meets internal standards, industry best practices, and regulatory requirements from the moment it's created. AI coding assistants now generate a significant portion of enterprise code, with nearly half of it being machine-written. However, these tools are not trained on an organization's specific security policies. Reports indicate that roughly half of AI-generated code introduces known vulnerabilities, and these risks are accelerating. Salt Code addresses this by using Salt's Posture Governance Engine. This engine defines security and compliance standards once and applies them across the entire development lifecycle. It connects to the tools developers already use, making AI coding assistants generate compliant code by default. This matters because it helps organizations secure their software development as AI coding becomes more prevalent. This is an AI-generated audio summary. Always check the original source for complete reporting.

Israel's Salt Security unveils platform to secure enterprise AI agents.

Israel's Salt Security unveils platform to secure enterprise AI agents. Israeli-founded Salt Security unveils the industry's first agentic security platform for enterprise AI, providing visibility and control over AI agent. March 18, 2026 at 4:12 pm - Pesach Benson - Security Jerusalem, 18 March, 2026 (TPS-IL) - Israeli-founded Salt Security announced the launch of what it calls the industry's first agentic security platform, aimed at securing enterprise AI systems built on large language models, MCP servers and APIs. The platform provides organizations with visibility and control over how AI agents interact with data, workflows and systems - a growing risk as adoption accelerates. CEO Roey Eliyahu said the key concern is not just what AI agents say, but what they can do through connected systems. The platform introduces new tools for monitoring and responding to threats in real time, helping companies safely scale AI deployment while maintaining security across increasingly complex environments.

Salt Security launches agentic security platform for LLMs, MCP servers and APIs

Salt Security has launched the Salt Agentic Security Platform, designed to secure the connections between large language models, Model Context Protocol servers and APIs that enable AI agent behaviour in enterprises. The company raised the platform announcement at a $1.45 billion valuation. The platform introduces two new security capabilities: Agentic Security Posture Management for continuous discovery and governance, and Agentic Detection and Response for real-time threat detection. Salt Security maps what it calls the "Agentic Security Graph" to help organisations understand not just what AI agents can generate, but what actions they can take across enterprise systems. Early customer Siemens reported improved visibility and protection for scaling AI deployments. The platform addresses growing security risks as enterprises deploy more autonomous AI agents with access to sensitive data and workflows.

Salt Security launches GenAI-powered API summaries translating complex endpoints into plain English

Salt Security has launched AI-powered features to address the "Context Crisis" in API security, including Salt AI API Summaries that translate complex API schemas into plain English explanations. The GenAI engine automatically generates natural-language summaries for every endpoint, answering questions about purpose, data handling and consumers in seconds. The company also introduced a redesigned Deep Context Side Drawer that organises API telemetry using Domain-Driven Design, displaying schema visualisation, threat intelligence and configuration gaps without requiring source code access. The tools aim to bridge the skills gap between security teams and developers by enabling junior analysts to understand complex technical services instantly. Both features are immediately available to all Salt Security customers. The company specialises in API security and AI governance for digital businesses.

Salt Security adds Databricks and Netlify integrations for API security across AI workloads and edge architectures

Salt Security has announced two new integrations expanding its API security platform: the Salt Databricks Connector and the Salt Netlify Collector. The additions aim to provide security teams with comprehensive API visibility across enterprise environments. The Databricks Connector specifically targets the "Agentic Action Layer", identifying Model Context Protocol servers and AI agents that connect proprietary data models to external systems. It provides visibility into which APIs and data sources internal AI agents are accessing, filling a gap that infrastructure scanners miss. The Netlify Collector extends Salt's traffic analysis to decoupled frontend applications and Jamstack architectures, ensuring security coverage as organisations push logic to the edge. Both integrations are immediately available as part of the Salt Illuminate platform, reinforcing the company's "Universal Visibility" strategy for API security and AI governance.
