What’s the difference between ASPM and DAST, SAST, or SCA?

AppSec tools are evolving and so is the confusion around what each tool contributes to an organization’s overall security posture. Dedicated application security posture management (ASPM) platforms have emerged as a way to consolidate visibility across security tools, but their primary role is vulnerability data aggregation and they’re not a substitute for the testing technologies they integrate with.

Quick intro to ASPM, DAST, SAST, and SCA

What is ASPM?

Application security posture management is a relatively new category of tools that aggregate findings from multiple AppSec sources to provide centralized risk visibility. ASPM tools help security teams understand what assets they have, track vulnerabilities across pipelines, and prioritize remediation. However, they depend on integrations with testing tools like DAST, SAST, and SCA to supply actionable data. 

Existing ASPMs may, on occasion, also bundle an open-source SAST, DAST, or SCA scanner to have at least some testing functionality out of the box. Similarly, a few existing AppSec vendors include modern ASPM-like features that combine results from multiple scanners, including DAST and API security findings. “I like to think of it as the production of primary data (finding vulnerabilities) from the scanners, and then the analysis and interpretation of the data in the ASPM,” explains Jonny Stewart, Director of Product Management at Invicti. “There’s a growing need to analyze and prioritize the data, as everyone has more vulnerabilities than resources to remediate them. I expect the next addition to ASPM offerings to be automated remediation or at least suggestions for remediation, potentially driven by AI.”

When to use ASPM:

• To centralize and correlate findings from multiple AppSec tools
• To gain visibility into application risk posture
• To track and prioritize vulnerabilities across the SDLC

ASPM strengths:

• Centralized reporting and analytics
• Asset discovery and risk tracking
• Supports governance and compliance

ASPM limitations:

• Does not perform testing itself
• Accuracy and value depend entirely on integrated tools
• Cannot independently evaluate or prioritize potential risks

What is DAST (dynamic application security testing)?

DAST tools scan live applications in runtime to find real, exploitable vulnerabilities from the outside in. DAST simulates how an attacker would interact with your application, testing for issues like cross-site scripting (XSS), SQL injection, authentication flaws, and logic bugs. Solutions like Invicti go further with proof-based scanning to confirm vulnerabilities and eliminate false positives.

When to use DAST:

• To validate vulnerabilities in running applications
• As part of security testing in staging or production
• To assess security from an external attacker’s perspective

DAST strengths:

• Finds real, exploitable vulnerabilities
• No source code access required
• Works across different tech stacks and environments

DAST limitations:

• Requires a running and accessible application
• May miss issues in assets that aren’t running during the scan

What is SAST (static application security testing)?

SAST tools analyze source code, binaries, or bytecode to detect potential vulnerabilities before the application is compiled or deployed. While helpful for early-stage scanning and enforcing secure coding practices, SAST often struggles with false positives and lacks context about how code behaves in production.

When to use SAST:

• Early in development to catch coding issues
• As part of secure coding workflows
• To audit proprietary source code for security flaws

SAST strengths:

• Enables shift-left security to find issues early
• Works on static code without a running app
• Can be used to enforce secure coding standards

SAST limitations:

• High rates of false positive or non-actionable alerts
• Can’t detect runtime-specific issues
• Requires access to source code

What is SCA (software composition analysis)?

SCA identifies and evaluates the open-source components and third-party libraries in your application. It flags known vulnerabilities in dependencies and helps ensure license compliance. While static SCA tools are essential for managing supply chain risk, they typically don’t validate whether those vulnerabilities are reachable or exploitable in your environment.

When to use SCA:

• To manage open-source and third-party components
• To identify license or compliance risks
• As part of software supply chain security

SCA strengths:

• Critical for managing third-party risk
• Helps ensure license compliance
• Fast scans and wide language support

SCA limitations:

• Doesn’t confirm exploitability
• Limited visibility into custom code
• Requires frequent updates to vulnerability databases

Static vs. dynamic SCA

SCA is usually understood as static analysis of software libraries and this is how most standalone tools work, but application components can also be detected at runtime based on fingerprinting and other methods. Vulnerability scanners that detect outdated or known vulnerable libraries and tech stack components are, in effect, performing dynamic (or runtime) SCA.

ASPM vs. DAST, SAST, SCA: Key differences

	ASPM	DAST	SAST	SCA
Runtime analysis	No	Yes	No	No
Source code access required	No	No	Yes	Sometimes
Finds exploitable vulnerabilities	No	Yes	No	No
False positives risk	Depends on testing tools	Low (for advanced DAST tools)	High	Moderate
Developer-ready remediation data	Limited (depends on specific tools)	Yes	Yes	Yes
Best for	Risk visibility	Real-world validation	Shift-left scanning	Open-source hygiene

Why a DAST-first approach is essential in 2025

As AppSec stacks get more complex while the scale and speed of development keeps growing, it’s more important than ever to cut through the noise and focus on real, exploitable risk. DAST remains the only technology that tests running applications the way an attacker would—without assumptions but with validation. With advanced DAST technologies such as Invicti’s proof-based scanning, teams can:

• Eliminate false positives at scale
• Prioritize based on confirmed impact
• Automate remediation workflows with confidence

While ASPM platforms help visualize AppSec posture and consolidate tooling, they rely entirely on the fidelity of the tools feeding them. A DAST-first approach ensures that those insights are rooted in actual application behavior, not static assumptions or theoretical issues.

How Invicti goes beyond ASPM

Invicti integrates with ASPM platforms as a source of DAST results but also delivers capabilities ASPM alone can’t provide:

• Proof-based scanning: Automatically confirms major exploitable vulnerabilities with 99.98% accuracy
• Comprehensive DAST+IAST coverage: Pinpoints vulnerable code from runtime behavior
• DevSecOps integrations: Automates testing in CI/CD and ticketing systems
• Prioritized reporting: Helps teams focus on what’s real, critical, and actionable

More than that, the Invicti platform itself can act as an integrated AST and ASPM combo by aggregating results from its native DAST, IAST, API security, and dynamic SCA alongside partner-supplied results for SAST, static SCA, and Container Security.

If you’re looking for an ASPM, you’re really looking for a way to separate AST noise from signal. Far from replacing security testing tools, ASPM should extend their value—and that value starts with accurate, validated, low-noise vulnerability data from tools like Invicti.
