# Threat Modelling Services - DSecure.me > Identify security risks before they become vulnerabilities. Expert threat modelling using STRIDE, PASTA, and OWASP methodologies. Build security into your system design. Source: https://dsecure.me/en/threat-modelling/ --- # Threat Modelling Identify and address security risks during design - before they become expensive vulnerabilities in production. Build secure systems from the ground up. Fixing security vulnerabilities after deployment is expensive and disruptive. What if you could identify and address security risks during the design phase, when changes are easy and inexpensive? Threat modelling gives you exactly that - a structured approach to understanding how attackers might compromise your system and designing defenses before writing a single line of code. Traditional penetration testing finds vulnerabilities in existing systems. Threat modelling works earlier in the development lifecycle, analyzing your architecture, data flows, and business logic to identify potential security issues. This proactive approach helps you make informed security decisions during design, saving time and money while building more secure systems. Our threat modelling services help organizations of all sizes - from startups designing their first product to enterprises architecting complex systems. We facilitate collaborative sessions with your development, security, and business teams, producing actionable threat models that guide secure development. You'll understand what assets need protection, what threats you face, and what security controls to implement - before committing to expensive architectural decisions. ### Our Approach Our threat modelling methodology draws from multiple industry frameworks including OWASP Threat Modeling, Microsoft STRIDE, and PASTA. We follow OWASP principles for identifying threats to web applications, APIs, and mobile systems, ensuring coverage of common vulnerability patterns. Our approach is practical and collaborative - we don't just deliver a document, we facilitate working sessions that transfer knowledge to your team. We help you understand not just what threats exist, but why they matter to your business and how to address them cost-effectively. ### Get In Touch Email contact@dsecure.me Address ul.

We identify security-critical components, single points of failure, and architectural patterns that could introduce vulnerabilities. Whether you're building new systems or evolving existing ones, we help you understand the security implications of architectural decisions before they're implemented. ### STRIDE Threat Analysis Systematic identification of threats using industry-standard methodology We apply the STRIDE methodology (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) to systematically identify threats to your system. This structured approach ensures comprehensive coverage across all threat categories. We examine each component and data flow, identifying how attackers might compromise authentication, manipulate data, deny actions, steal information, disrupt services, or gain unauthorized access. ### Data Flow Security Analysis Map and secure the flow of sensitive data through your system We trace how sensitive data moves through your system - from user input through processing, storage, and output. We identify where data is most vulnerable, what security controls protect it at each stage, and where additional protection is needed. This analysis is crucial for meeting regulatory requirements (GDPR, HIPAA, PCI-DSS) and ensuring sensitive information is protected throughout its lifecycle. ### Attack Surface Mapping Identify and evaluate all potential entry points for attackers We map your entire attack surface - APIs, web interfaces, mobile apps, third-party integrations, and internal systems. We identify which components are exposed to untrusted networks, which accept user input, and which process sensitive data. Understanding your attack surface helps prioritize security efforts on the areas that matter most. We also identify opportunities to reduce attack surface through architectural changes. ### Security Control Recommendations Design appropriate security controls for identified threats For each identified threat, we recommend specific security controls aligned with your risk tolerance and budget. These include authentication mechanisms, authorization models, encryption requirements, input validation strategies, logging and monitoring capabilities, and secure configuration practices. Our recommendations are practical and prioritized, helping you focus resources on the most critical security controls first. ### Threat Model Documentation & Maintenance Create living documentation that evolves with your system We produce clear, actionable threat model documentation including architecture diagrams, data flow diagrams, identified threats, recommended controls, and risk assessments. More importantly, we help you establish processes for maintaining threat models as your system evolves. Security isn't a one-time activity - we ensure your team can update threat models when adding features, changing architecture, or responding to new threats. ## Ready to Get Started?
