Dawnguard Security Architecture Platform

Dawnguard is an Amsterdam-based cybersecurity startup, with a New York office, that embeds security into system architecture at design time instead of adding it after deployment. It emerged from stealth in July 2025 with a USD 3 million pre-seed round led by 9900 Capital.

The AI-native platform has four modules: Design generates and refines cloud architectures on a collaborative canvas, Discover connects cloud environments and visualizes resources, Deploy resolves issues and optimizes deployed workloads, and Dawnguard MCP delivers security and compliance expertise to coding assistants. It can output infrastructure as code from the architecture.

• Design: generates and refines architectures on a collaborative canvas from text or images.
• Discover: connects cloud environments and visualizes resources and relationships.
• Deploy: browses insights, resolves issues and optimizes deployed workloads.
• Dawnguard MCP: gives coding assistants security and compliance expertise.
• Architecture-to-code: automates deployment from the designed architecture.
• AI-driven insights: highlight risk and cost issues across resources.

Cloud architects at Vietnamese banks or fintechs can review proposed designs for security gaps before deployment. Product teams using AI coding tools can add security rules through the MCP module.

Finds vulnerabilities at the design stage, before cloud infrastructure is deployed.

Generates architectures and infrastructure code with security and compliance built in.

Reduces post-deployment drift through continuous discovery of cloud environments.

Extends security guidance to AI coding assistants through MCP.

AI coding assistants speed up cloud builds and widen the design-level security gap, so teams look to shift security left into architecture. Vietnamese software teams and banks adopting cloud and AI coding tools face the same pressure.

Pre-seed of USD 3 million announced 31 July 2025, led by 9900 Capital. Founders are Mahdi Abdulrazak (CEO) and Kim van Lavieren (CTO). Footer lists Amsterdam and New York offices.
