A model context protocol (MCP) tool can claim to execute a benign task such as “validate email addresses,” but if the tool is compromised, it can be redirected to fulfill ulterior motives, such as exfiltrating your entire address book to an external server. Traditional security scanners could flag suspicious network calls or dangerous functions and […]
The New Baseline for AI Security AI is no longer an experimental capability or a back-office automation tool: it is becoming a core operational layer inside modern enterprises. The pace of adoption is breathtaking. Yet, according to Cisco’s 2025 AI Readiness Index, only 29 percent of companies believe they are adequately equipped to defend against […]
Artificial intelligence and machine learning (AI/ML) models are increasingly shared across organizations, fine-tuned, and deployed in production systems. Cisco’s AI Defense offering includes a model file scanning tool designed to help organizations detect and mitigate risks in AI supply chains by verifying their integrity, scanning for malicious payloads, and ensuring compliance before deployment. Strengthening our […]
The Rise of Agent Networks: A New Security Frontier Emerging Agent-to-Agent (A2A) frameworks have emerged to support organizations as they move from isolated AI applications to interconnected networks of autonomous agents. A2A enables software agents to discover, authenticate, and collaborate across organizational boundaries, unlocks unprecedented automation capabilities. A2A also introduces an expanded attack surface, and […]
The conversation around AI and its enterprise applications has rapidly shifted focus to AI agents—autonomous AI systems that are not only capable of conversing, but also reasoning, planning, and executing autonomous actions. Our Cisco AI Readiness Index 2025 underscores this excitement, as 83% of companies surveyed already intend to develop or deploy AI agents across […]
AI models have become increasingly democratized, and the proliferation and adoption of open weight models has contributed significantly to this reality. Open-weight models provide researchers, developers, and AI enthusiasts with a solid foundation for limitless use cases and applications. As of August 2025, leading U.S., Chinese, and European models have around 400M total downloads on […]
Today, we are excited to share that the SecureBERT 2.0 model is available on HuggingFace and GitHub with an accompanying research paper. This release marks a significant milestone, building on the already widely adopted SecureBERT model to unlock even more advanced cybersecurity applications. Just see this unparalleled performance across real-world tasks: In 2022, the first […]
In today’s rapidly evolving AI landscape, organizations face a critical challenge: how to harness the transformative power of generative AI while maintaining robust security and compliance standards. As enterprises deploy increasingly sophisticated GenAI applications, the need for comprehensive protection across the entire AI lifecycle has never been more urgent. Today, Cisco is pleased to announce […]
As enterprises integrate AI agents into their technology stacks, these agents increasingly rely on external tools and services to navigate complex technology environments. Model Context Protocol (MCP) enables AI models to access external functionalities, tools, resources, and prompts without custom API integrations. At Cisco, we recognize that MCP adoption and utilization brings new and complex […]
