Welcome Home

Welcome to arc5. (5) is for Security!

This blog is dedicated to exploring how to build resilient, scalable, and secure systems right from the start.

We focus on building products with Secure by Design principles at the core, emphasizing minimalism, simplicity, and software-defined perimeter approach. This space is built for security engineers, architects, and curious learners who want to dive deep into designing and building systems that can withstand evolving threats without compromising on scalability or business agility. Expect practical insights, architectural patterns, and security strategies that bridge theory and real-world application.

What You’ll Find Here

• In-depth technical guides on building secure, distributed systems and microservices.
• Educational resources covering Zero Trust, SDP, least privilege, and defense-in-depth.
• Systems design principles focused on scalability, fault tolerance, and minimal complexity.
• Practical patterns for secure service-to-service communication and access control.
• Thoughtful analyses of real-world architectures and emerging technologies.

Core Design Principles

• Secure by Design: Embed security into every stage of your solution development.
• Minimalism & Simplicity: Reduce complexity to enhance security, clarity, and maintainability
• Least Privilege & Zero Trust: Assume breach, verify everything.
• Scalability & Resilience: Build systems that grow and adapt.
• Software-Defined Perimeter: Dynamic, identity-driven access control.
