Cisco has been a long-standing partner in securing Black Hat conferences worldwide, providing the critical network infrastructure that ensures safe connectivity for all attendees. At Black Hat Asia 2026, we continued this tradition while introducing significant enhancements to our security capabilities through innovative integrations.

Two instances of Cisco Secure Access DNS forwarders were deployed as virtual appliances, to serve as key network components and provide essential security for both network infrastructure and attendee devices. Throughout the event, the system successfully processed over 16 million DNS queries, identified and blocked more than 234,000 encrypted DNS requests under Black Hat policy for Network Operations Center visibility.

Model Context Protocol (MCP) is a standardized protocol designed to enable AI applications and agents to interact with external tools, data sources, and workflows in a structured and dynamic way. One of the most significant innovations at this year’s event was the integration with MCP infrastructure to streamline SOC workflows. Traditional log analysis requires analysts to manually query log repositories. This a time-consuming and resource-intensive process that can delay threat detection and response. By developing a custom MCP server that enables seamless connectivity to Secure Access Reports API, we achieved real-time, conversational analysis of security events, significantly enhancing operational efficiency.

To further strengthen security posture, Cisco Secure Access MCP Gateway was implemented to enforce fine-grained access policies, ensuring that only authorized tools and personnel can interact with critical systems and sensitive information.

Cisco Secure Access Resource Connector was deployed to provide secure remote access to critical systems. Not all devices have built-in cloud management or VPN support. Resource Connector solves this problem by creating secure path to the target, which is accessible from public URL generated by Secure Access platform. Integration with Duo IAM ensured strong authentication takes place before access is allowed.

The deployment at Black Hat Asia 2026 successfully demonstrated the evolution of network security through strategic integration of advanced security platforms, AI-powered automation, and zero-trust access controls. These innovations not only protected the conference infrastructure but also validated emerging security technologies in a high-stakes, real-world environment. The insights gained will inform future deployments and contribute to the ongoing development of more resilient security architectures.
