You cannot protect what you do not know. Threat modeling systematically maps the attack paths relevant to your system, so defenses can be proactive rather than reactive.
Why does your application need Threat Modeling?
Threat Modeling systematically identifies security threats before attackers exploit them. It is a proactive approach that answers "What can go wrong?" and "How do we protect ourselves?". With the model in place, your team already knows the attack vectors and the controls needed, which helps prioritize fixes and respond to incidents.
Our structured Threat Modeling identifies critical assets, maps real threats and defines security controls prioritized by risk, creating an actionable defense roadmap.
Risks the assessment helps you avoid
- Unknown attack surface
- Not knowing where you are vulnerable
- Misplaced priorities
- Investing in controls that do not protect critical assets
- Slow incident response
- No preparation for real-world attack scenarios
- Inadequate compliance
- Failing to meet risk management requirements

Investment: how does Threat Modeling pricing work?
The investment varies with the complexity of the system and the depth of the analysis:
| Size | Typical scope | Estimated timeline |
|---|---|---|
| Single Application | Standalone system or microservice | 3-5 days |
| Integrated System | Application with APIs and integrations | 5-8 days |
| Full Platform | Multiple systems and microservices | 8-15 days |
| Enterprise/Infrastructure | Full cloud + on-premise | 15-25 days |
Estimated timelines; each project's schedule is set in the proposal, based on scope.
Factors that influence pricing:
- Architecture complexity and number of components
- System criticality (PII, financial data, healthcare data)
- Existing security maturity
- Compliance requirements (PCI-DSS, HIPAA, LGPD)
- Scope: new system vs. legacy system

Frequently asked questions about Threat Modeling
What is threat modeling and when should you do it?
Threat modeling is the structured process of identifying, quantifying and prioritizing the threats to a system. Ideally it happens during the design phase, but it is equally valuable for systems already in production. It helps you understand 'what can go wrong' before it does.
What is the difference between STRIDE and PASTA?
STRIDE focuses on categorizing threat types (Spoofing, Tampering, and so on). PASTA is an end-to-end process that covers business context, technical analysis and risk assessment. STRIDE is more technical, PASTA is more business-oriented. We frequently use both.
Does threat modeling replace a pentest?
No, they are complementary. Threat modeling identifies theoretically possible threats and helps prioritize controls. A pentest validates whether those threats are exploitable in practice. Threat modeling is 'defensive planning'; a pentest is 'offensive validation'.
How long does a threat modeling engagement take?
The timeline depends on the scope, the complexity of the architecture and the level of detail required, and is estimated in the proposal, before you hire. When included in the scope, the work includes workshops with the technical teams.
Do you perform threat modeling on legacy systems?
Yes. Since legacy systems often have limited documentation, we start by reconstructing the architecture. It takes longer, but it pays off, because these systems tend to accumulate risk over time.
Do I need to know STRIDE and PASTA?
No. We lead the process: you bring knowledge of the system and the business, and we bring the threat modeling methodology. The work is collaborative.
Do you deliver visual documentation?
Yes. Depending on the scope, the delivery includes Data Flow Diagrams (DFD), attack trees, a risk matrix and a report with a threat catalog, recommended controls and an implementation roadmap.
Does it help with compliance?
Yes. Threat Modeling supports the risk management requirements of frameworks such as ISO 27001, PCI-DSS, SOC 2, NIST and LGPD, and produces documented evidence for audits.
