Secure Software Architecture & Design
Designing Software for Security & Resilience
Secure software isn’t just about clean code—it begins with architecture. Our service helps you integrate threat modelling, secure design patterns, and risk-aligned decisions from day one.
Security Starts with Architecture
Many organisations focus security efforts on code and testing, but overlook the foundational role of secure architecture. Without a strong design, even the most secure code can expose the business to risk. Threat modelling is skipped, security controls are bolted on later, and architectural decisions are made without considering how a threat actor might exploit them.
Design reviews—if they happen—often occur too late, making security fixes costly and complex. Without standardised design principles and patterns, security becomes inconsistent, dependent on individual developer awareness rather than system-level thinking.
At Morrisec, we support development teams in embedding security from the outset. From structured threat modelling workshops to establishing secure design principles tailored to your architecture, we help you make early decisions that reduce long-term risk. Whether designing new applications or modernising legacy systems, we ensure your design process includes the right controls, patterns, and risk visibility—so security is baked in, not patched on.
Secure Foundations. Resilient Outcomes.
Threat Modelling Support
We facilitate structured threat modelling sessions, helping teams identify potential threats and mitigation strategies early.
Secure Design Principles
We guide teams in applying consistent security design patterns aligned with your architecture, platform, and risk appetite.
Architecture Review & Advisory
We assess your current or proposed architecture and provide practical, context-driven security recommendations.
Risk-Based Decision Support
We help prioritise security decisions based on real business risk—not just theoretical threats.
Secure Design Documentation
We assist in capturing secure design patterns and principles for ongoing use across teams, ensuring consistency.
Adaptable to Any Environment
Whether you’re building microservices, serverless functions, or monolithic platforms, we tailor guidance to your environment and development practices.
