Question 1

sast vs dast vs sca

Accepted Answer

SAST vs DAST vs SCA: SAST analyzes source or binaries without running the app, DAST probes a live application like an attacker, and SCA inventories open-source dependencies for known CVEs. Use the free picker on this page, then run free DAST on Vulnify for authorized URLs.

Question 2

sca sast dast

Accepted Answer

SCA SAST DAST is the same trio as SAST vs DAST vs SCA. SCA checks packages, SAST checks your code, DAST checks the running site. Most teams run all three; start with free DAST if you have no tooling yet.

Question 3

sca vs sast vs dast

Accepted Answer

SCA vs SAST vs DAST is the same comparison in a different order. Sequence SCA in CI, SAST on pull requests, and DAST on staging. Vulnify covers the DAST stage for free online scans.

Question 4

sast dast sca

Accepted Answer

SAST DAST SCA are the three common application security scanner types. This free interactive guide picks which to run first for your scenario.

Question 5

sast vs sca vs dast

Accepted Answer

Yes. SAST vs SCA vs DAST is the same method split. SAST is first-party code, SCA is dependencies, DAST is runtime HTTP behavior.

Question 6

sca vs dast

Accepted Answer

SCA vs DAST: SCA finds known CVEs in libraries you imported; DAST finds exploitable behavior on a running URL. Use both. Free DAST is on Vulnify.

Question 7

dast vs sast vs sca

Accepted Answer

DAST vs SAST vs SCA is SAST vs DAST vs SCA reordered. DAST tests live HTTP; SAST tests code; SCA tests packages.

Question 8

dast scan vs sast scan

Accepted Answer

A DAST scan hits a running URL; a SAST scan reviews source without executing it. If you need findings this week on a site you own, run free DAST first, then add SAST in CI.

Question 9

sast vs dast

Accepted Answer

SAST vs DAST: SAST analyzes code without running the app; DAST probes the live app. This page compares both with SCA. It is a method picker, not a vendor bake-off.

Question 10

What is the difference between SAST, DAST, and SCA?

Accepted Answer

SAST (static application security testing) analyzes source code or binaries without executing the application. DAST (dynamic application security testing) probes a running app from the outside, finding exploitable flaws like SQL injection and XSS in live forms. SCA (software composition analysis) flags known CVEs in third-party dependencies. Most mature teams run all three at different pipeline stages for complete coverage.

Question 11

Should I use SAST or DAST first?

Accepted Answer

Start with DAST if you have no AppSec tooling yet. It surfaces high-impact runtime issues — SQL injection, XSS, exposed paths — without requiring CI setup. Add SAST once developers have a pull-request workflow and need pre-merge feedback on unsafe code patterns. Use the interactive picker above to get a scenario-specific recommendation.

Question 12

What does SCA scan for that SAST and DAST miss?

Accepted Answer

SCA identifies vulnerable versions of libraries listed in package manifests (npm, pip, Maven, and others) and checks them against CVE databases. SAST cannot reliably track dependency version ranges; DAST cannot see what packages are installed on the server. SCA is the only tool that directly addresses supply-chain risk from third-party libraries.

Question 13

Can I use SAST, DAST, and SCA together?

Accepted Answer

Yes — they are complementary, not competing. The recommended order: run SCA on every build to catch dependency CVEs, run SAST on pull requests to catch code-level patterns, and run DAST on staging before release to validate exploitable behavior. Vulnify provides free online DAST-style scanning for the live-application stage with no install required.

Dimension	SAST	DAST	SCA
What it tests	Source code / binaries	Running web application	Dependencies & packages
When it runs	CI pipeline, pre-merge	Staging or production-like URL	Build time / SBOM review
Typical owner	Developers	Security + QA	DevOps / AppSec
Finds SQLi in live forms	Sometimes (static patterns)	Yes — primary strength	No
Finds vulnerable npm package	Rarely	No	Yes — primary strength
Setup friction	Repo integration	URL + auth context	Lockfile / registry access
Vulnify fit	Use SAST in CI alongside Vulnify	Vulnify DAST — free online scan	Add SCA; use Vulnify for runtime gaps
