Who each one fits
SHIFT ASIA's published practice spans several testing disciplines, reaching as far as security testing. PFLB's published practice stays narrower: performance engineering, covering load and latency, is the entire published offering. A buyer arrives at this pair weighing whether to split a mixed testing scope across specialists or hand it to a vendor whose contract already reaches past load work into other ground.
A buyer in a regulated sector routes any new vendor through an internal supplier review before a contract is signed, and that review's questionnaire usually carries a line asking whether the vendor holds an external audit or certification. PFLB's published profile leaves that line unanswered, and what the buyer cannot estimate is how long the review will then take. That unknown sits inside the release plan rather than beside it, because approval gates the start of work and nothing about it can be scheduled in advance. Ask PFLB directly whether an audit exists before scoping a regulated engagement, and check the answer later against whatever the certificates field shows once it is published.
A tag is attached when the company's published fields meet its condition, never by judgement. Both lists come from the same closed vocabulary, so a tag missing from one side means the condition was not met, not that nobody looked.
PFLB
PFLB meets no applicability condition in this catalog. That is a statement about what its published fields show, not about the company.
SHIFT ASIA
Both meet the conditions for Performance engineering, so those conditions do not separate them.
Where the data runs out
Completeness against the 14 fields of the comparison checklist is 86% for PFLB and 79% for SHIFT ASIA. A field is counted as filled when a source confirms it, so a gap means nobody published it.
Neither company has a value recorded for these fields: Signs a BAA / GDPR DPA, Onboarding, Crowd tester pool, Device lab. The table shows those rows empty rather than estimating them.
Field definitions and the completeness checklist are on the methodology page. The sources behind each field are listed on the PFLB profile and the SHIFT ASIA profile.
Questions
- How many industries appear on each company's published profile?
- PFLB's published profile names five industries, Ecommerce, Banking, Energy and utilities, Education and Healthcare, checked 2 September 2026. SHIFT ASIA's published profile names one industry, Education, checked 3 September 2026. Education is the only industry named on both profiles. Every other industry on PFLB's list belongs to PFLB alone.
- Can either company be hired as testers embedded in the buyer's own team?
- SHIFT ASIA's published profile lists Staff augmentation as its engagement model, checked 3 September 2026. PFLB's published profile lists Managed testing service, Project work and Continuous testing program, checked 2 September 2026. No model named on SHIFT ASIA's profile appears on PFLB's. A buyer taking that route should confirm which entity employs the testers, since staff augmentation moves day-to-day direction of the work to the buyer.

Every fact about a company comes from a listed source. A field without a source stays empty. A certificate counts as confirmed only when a registry, certificate or auditor report backs it; a certificate the company only claims about itself is published separately, under that label. Vendors can request a correction at hello@qa-rating.com. A correction is applied when it comes with a public source.
