Matias Carlos Siri Brenta

As a Cybersecurity Enterprise Architect, I design and guide secure, scalable cloud and hybrid architectures that enable Siemens teams to build and operate resilient services across complex environments. I work across engineering, product, and platform teams to simplify architecture decisions, embed security by design, and translate technical challenges into practical solutions that deliver business value. My focus is on modernizing workloads, improving cloud posture, and ensuring secure integration between platforms while keeping architectures efficient, consistent, and easy to operate.

As a Cloud Optimization Specialist Solutions Architect I collaborate with partners and customers across industries to design and implement secure, resilient, and cost-effective workloads based on the AWS Well-Architected and Cloud Adoption Frameworks. With a passion for cloud technology and a commitment to exceptional customer service, I approach my work with a positive, customer-focused mindset, simplifying complex concepts to deliver tangible business value.

I serve as a Specialist Solutions Architect in security. My focus areas include Threat Detection, Incident Response (TDIR), and providing proactive technical guidance to enhance customers' security operations. I regularly deliver sessions and security talks like AWS re:Inforce, focusing on cloud security best practices. These sessions highlight how automation, centralized controls, and robust architecture enable rapid and effective responses to evolving security events. Participants learn the fundamentals of security event response and gain practical insights through example scenarios for their own event response planning. Additionally, I contribute to the community and represent AWS at various events through presentations and workshops.
