STRIDE vs PASTA: threat modeling methodologies compared
STRIDE and PASTA are two of the most widely used threat modeling methodologies — but they answer different questions. Here's how they differ, when to use each, and how to get the benefits of both.
What is STRIDE?
STRIDE is a threat-classification framework from Microsoft that sorts threats into six categories: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege. It's technical, systematic, and fast — making it a natural fit for analyzing individual features and changes.
What is PASTA?
PASTA (Process for Attack Simulation and Threat Analysis) is a seven-stage, risk-centric methodology. It starts from business objectives, simulates realistic attacks, and prioritizes threats by business impact. It's more thorough and better suited to high-stakes systems and executive or compliance audiences.
STRIDE vs PASTA at a glance
| STRIDE | PASTA | |
|---|---|---|
| Type | Threat classification | Risk-centric process |
| Focus | Technical threats | Business risk & attacks |
| Structure | 6 threat categories | 7 sequential stages |
| Speed | Fast | Thorough, heavier |
| Best for | Per-feature / per-change | High-stakes, exec & compliance |
When to use which
Reach for STRIDE when you want quick, systematic, developer-friendly coverage of technical threats — it's ideal for analyzing every feature or change. Reach for PASTA when you need threats prioritized by business impact, typically for your most critical systems or for compliance and executive reporting.
In practice, the two are complementary rather than competing: PASTA can frame business risk and scope, while STRIDE supplies the systematic technical enumeration within it.

What is the difference between STRIDE and PASTA?
STRIDE is a threat-classification framework that sorts threats into six categories (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege). PASTA is a seven-stage, risk-centric methodology that ties threats to business impact and simulates real attacks. STRIDE is faster and more technical; PASTA is more thorough and business-aligned.
Should I use STRIDE or PASTA?
Use STRIDE when you want fast, systematic, developer-friendly coverage of technical threats — ideal for per-feature or per-change analysis. Use PASTA when you need risk prioritized by business impact, often for high-stakes systems, executive reporting, or compliance. Many teams benefit from both.
Can you use STRIDE and PASTA together?
Yes. They operate at different levels: PASTA can frame the business risk and scope, while STRIDE provides the systematic technical threat enumeration within it. Virantis runs both automatically, so you get STRIDE's coverage and PASTA's risk-centric view without doing either by hand.
