Davor Grce is an accomplished Infrastructure and Network Architect with extensive experience designing, implementing, and governing complex enterprise architectures across multi-cloud, hybrid, and on-premises environments. He specializes in architecting secure, resilient, and scalable network and security infrastructures built on industry-leading platforms — including Palo Alto, Check Point, Fortinet, Cisco Firepower, and VMware.
As a Microsoft Certified Azure Solutions Architect Expert, Check Point Security Expert, Fortinet Security Expert, Cisco Certified Network Professional, and VMware Certified Professional, he brings a comprehensive understanding of infrastructure, virtualization, cloud platforms, automation, and security engineering across the full stack.
Davor has led the design and implementation of hybrid cloud architectures using Azure, AWS, and Google Cloud — ensuring seamless integration of IaaS, PaaS, container, and network-centric cloud security services with existing enterprise systems. His architectural approach combines deep technical expertise, structured methodology, and a strong foundation in governance frameworks including TOGAF, BTABOK, and ISO 27001.
His enterprise consulting work spans architecture standards, governance models, modernisation roadmaps, and operational frameworks following Agile and ITSM methodologies. He produces high-quality HLDs, LLDs, system blueprints, dependency mappings, and risk analyses that align infrastructure designs with organisational goals, regulatory requirements, and industry best practices.
“He provides a level of technical leadership and architectural depth that aligns people, processes, and technology into a unified and forward-looking infrastructure vision.”
