Threat Modeling
Fixing a security flaw found in the design phase costs 100x less than in production. We'll identify threats using STRIDE and PASTA methods before you write the first line of code. You get a secure product without costly redesigns.
Architecture flaw means rewriting the entire system
Threat Modeling - find threats before code
Data Flow Diagrams
We map data flows and trust boundaries
STRIDE Analysis
We identify threats for each component
Mitigation Plan
Concrete security controls to implement
Payment System Redesign for €120,000
A fintech launched a payment system. After three months, PCI DSS audit revealed fundamental architecture flaws - no environment separation, sensitive data in logs, weak encryption. Redesign and reimplementation: €120,000 and 6-month delay.
Without threat modeling:
- Fundamental security flaws in architecture
- Costly redesign and code rewriting
- Time-to-market delays, competitive advantage loss
- Compliance violations and potential fines
STRIDE + PASTA = Complete Threat Map
We use proven threat modeling methodologies used by Microsoft, Google, banks. We identify threats systematically, not relying on “intuition.”
What you get:
- Data Flow Diagrams with components, data flows, trust boundaries
- Complete threat list for each component (STRIDE)
- Prioritization by risk (DREAD: Damage, Reproducibility, Exploitability, Affected users, Discoverability)
- Security requirements for implementation
- Mitigation plan - concrete controls for each threat
- Attack trees showing attack scenarios
Who Is It For?
This service is for you if:
- You’re designing a new application or feature and want to do it securely
- You must meet compliance requirements (PCI DSS, ISO 27001, HIPAA)
- You’re building an application handling sensitive data or money
- You want to avoid costly security bug fixes later
- You need security requirements for the development team
Threat Modeling Methodologies
STRIDE - Threat Analysis
Systematic identification of 6 threat categories:
- Spoofing - impersonating another user/system
- Tampering - modifying data, code, configuration
- Repudiation - denying performed action
- Information Disclosure - sensitive information leak
- Denial of Service - preventing system use
- Elevation of Privilege - gaining higher privileges
PASTA - Process for Attack Simulation and Threat Analysis
Risk-centric methodology in 7 steps:
- Business objective definition
- Technical scope definition
- Application decomposition (DFD)
- Threat analysis
- Vulnerability analysis
- Attack modeling
- Risk analysis and mitigations
DREAD - Risk Prioritization
Each threat rating on 1-10 scale:
- Damage - how much damage?
- Reproducibility - how easy to repeat attack?
- Exploitability - how easy to exploit?
- Affected users - how many users affected?
- Discoverability - how easy to find vulnerability?
For What Systems?
We apply threat modeling to:
- Web applications - SaaS, portals, e-commerce
- Mobile applications - iOS, Android, fintech, healthtech
- APIs - REST, GraphQL, microservices
- IoT - connected devices, smart home
- Cloud - AWS/Azure/GCP architectures
- Blockchain - smart contracts, DeFi

Common questions about Threat Modeling.
When is the best time to conduct threat modeling - before or during development?
Best before writing code, during the architecture design phase. Fixing a security flaw in design costs 100x less than in production. Threat modeling can also be conducted for an existing system before a major change.
What is the difference between STRIDE and PASTA, and which methodology do you use?
STRIDE identifies 6 threat categories (Spoofing, Tampering, Repudiation, Information Disclosure, DoS, Elevation of Privilege) and works well for individual components. PASTA is risk-centric and links threats to business objectives. We select the methodology based on the project - often combining both.
How long does threat modeling take and what do I receive at the end?
Delivery takes 3-10 business days. We provide Data Flow Diagrams, a complete threat list with DREAD prioritization, security requirements for implementation and a mitigation plan with specific controls.
Is threat modeling necessary if we do penetration testing?
Yes - these are complementary approaches. Threat modeling finds architectural flaws (e.g. lack of environment separation, weak authorization model) before you write code. Pentests verify the finished system. Without threat modeling, pentesters will find problems, but fixing them will be many times more expensive.
