QA vendors vs efficacy labs
A lab answers how well one version detects threats in the lab's tests. A QA vendor answers whether every build of your product works as specified.

Short answer
Efficacy labs certify detection and protection rates of a product version against their own test scenarios and publish the result for buyers. QA vendors work inside your release cycle against your requirements and report to your engineers. They answer different questions, so the ranking lists QA vendors only.
What each one tests
An efficacy lab runs a product version against a threat set and a clean-file set it selects, under a published methodology. The output is a score or a certificate that buyers compare across vendors.
A QA vendor runs your product against your requirements on every build: installation, upgrades, the compatibility matrix1, performance cost, management consoles, APIs and false-positive regression2. The output is a defect list and a release decision; the security product QA checklist lists each item.
Side by side
| Question | Efficacy lab | QA vendor |
|---|---|---|
| Who sets the test scope | The lab | You |
| When it runs | Selected releases | Every build or sprint |
| Who reads the result | Buyers and the market | Your engineers |
| What it covers | Detection and protection outcomes | Function, compatibility, performance, regression |
| Typical output | Score, award or certificate | Defects, test reports, release sign-off |
How to use both
- Keep the regression corpus separate. Benign and malicious samples used by your QA vendor for EDR3 regression should not be the set you tune for a lab submission.
- Ask the QA vendor for build-level evidence. A lab result for one version says nothing about the next build; dimension 3 of the methodology scores the test types a vendor has evidenced on security products.
- Treat a lab certificate as a market requirement. When a tender asks for one, it sits beside QA, not in place of it.
Why labs are not ranked here
Scope gate condition 3 excludes organisations whose main business is certifying detection rates. No efficacy lab was among the candidates. Any candidate excluded for this reason would appear on not published. The ranking does not rate any product's detection quality.
- 1 compatibility matrix: A grid listing the operating systems, browsers, devices and versions a product must be tested on, usually ranked by how many users each combination covers. Source
- 2 false-positive regression: A case where a security tool starts flagging harmless activity as malicious after an update, when it did not do so in an earlier version. Source
- 3 EDR: Software that watches laptops, servers and phones for suspicious behavior, records what it sees, and alerts administrators so they can investigate and respond. Source
Questions buyers ask
What does a QA vendor test that an independent test lab does not?
Installation, upgrades, compatibility with customer platforms, performance cost, management consoles, APIs and regression of your own requirements on every build. An efficacy lab tests detection and protection against its own scenarios on release candidates.
Who does a QA vendor work for compared with a test lab?
A QA vendor works for you and reports to your engineering team. A lab works to its own published methodology, and its results are meant for buyers and the market.
Can lab results replace our own QA?
No. A lab result says how one version performed in the lab's scenarios on the test date. It says nothing about whether the next build installs on every supported OS or whether a fixed bug came back.
When do we need a lab certification rather than a QA vendor?
When a buyer, a tender or a regulator asks for an independent detection or protection result. That is a market requirement, not a release-quality requirement, and it sits beside QA.
How are false positives handled by labs and by QA vendors?
A lab counts false positives on its clean-file set and reports a rate. A QA vendor keeps a benign corpus of your customers' typical software and fails a build when a known-clean item starts alerting.
Should a security product company use both a QA vendor and a lab?
Use them for different questions: the QA vendor on every build and the efficacy lab on selected releases. Keep the QA regression corpus separate from anything submitted to a lab.
