Continuous testing sounds like one service, but does it mean the same thing across every vendor that offers it?

Not consistently. Case studies published in this composition describe two different kinds of continuous work: some describe continuous monitoring of an attack surface, validation ahead of a scheduled penetration test, or thousands of assets kept under ongoing review, while others describe continuous game playtesting or continuous load testing under simulated traffic. Carrying the same label leaves that question open, since the label describes a recurring schedule and nothing about which kind of testing recurs. Read a case study before assuming which one a given vendor runs.

Continuous testing runs as an ongoing subscription across many months. Is there a monthly cost or a minimum commitment period I can compare before signing?

Not from a comparison standpoint. The catalog carries no separate field for a monthly cost or a minimum commitment period for any company here. An hourly rate, where published, does not by itself convert into what a multi-month engagement scheduled against an ongoing release cycle will cost, since neither a floor nor a ceiling on that duration is recorded anywhere on this page. Comparing subscription-style pricing across vendors here means asking each one directly for a monthly or retainer figure.

For an engagement that runs continuously for months, does a company's reported team size tell me whether the same testers stay on my account the whole time?

No. A reported team size on this page counts a company's entire staff, not a dedicated group assigned to one client for one engagement. In this composition, 6 of the 12 companies report a band of 51 to 200 people, 3 report 201 to 500, 2 report a band below 51 people, and 1 reports a band above 500, and none of those bands changes once a continuous arrangement starts or ends. Whether the same testers stay on one account across months of work is a staffing detail this catalog does not record.

A case study for continuous testing usually reports one big result, like time saved or issues caught in a single stretch. Does that number describe what keeps happening every release, or just an initial jump when the engagement started?

A case study on this page reports the result of one stretch of work: a share of testing time saved for a single client, or a percentage cut from the time spent preparing for a security assessment. Continuous testing implies work every month, and the catalog carries no field for a sustained-improvement metric apart from the one figure a case study already reports. A published number here is a snapshot of one period, and nothing on this page tracks whether the result repeats on the next release.

Continuous testing as a field on twelve company profiles

Continuous testing is an engagement model: a value recorded on a company profile for how test work is scheduled against a client's own release cycle, on an ongoing basis, distinct from staffing once for a single fixed piece of work. Twelve companies carry this model, and that structural fact places a company on this page regardless of team size, founding year or headquarters location. The five applicability tags described below record a narrower, separately verifiable claim on top of the model itself: a specific delivery location, a security service paired with a certificate or a case study, or a specific published case behind a metric. Eleven of the twelve companies in this composition carry at least one of the five tags; Halo Security carries none of them. Four of the eleven tagged companies, including Global App Testing and Edgescan, carry two of the five tags apiece; the other seven carry exactly one tag each.

Five tags built from delivery geography, security evidence and one published metric

Seven of the twelve companies carry the Nearshore for the EU tag and four carry the Security focus tag, and the two tags read different kinds of evidence: one a delivery location, the other a security service backed by a published case study. Two of the twelve, Cobalt and Edgescan, carry both tags together. The other five Nearshore for the EU holders, Global App Testing, BreachLock, PlaytestCloud, Blaze Information Security and Ethiack, do not carry Security focus. Two of the four Security focus companies, NetSPI and Bishop Fox, do not carry Nearshore for the EU. Two of the twelve carry the Nearshore for the USA tag, read from a second delivery region: Packetlabs and NetSPI. The two remaining tags each reach a single company. Crowdtesting at scale asks for a published tester pool with a source on top of the crowdtesting model, a higher bar than the location-only criteria above, and only Global App Testing meets it here. Performance engineering asks for a case study carrying one measurable result rather than a service listing alone, and only PFLB meets it here.

Fields left blank across this set of twelve

A framework or tool list is unrecorded for 11 of the 12 companies in this composition, and a published hourly rate is separately unrecorded for 11 of the 12 companies, leaving little published basis to compare tooling fit or blended cost across the set. A named client stage is unrecorded for 7 of the 12 companies. A confirmed certificate is unrecorded for 4 of the 12 companies, and external reviews on outside platforms are unrecorded for 4 of the 12 companies. A published case study is unrecorded for 3 of the 12 companies. Named clients are unrecorded for only 2 of the 12 companies, a smaller gap than any other field in this list.

Reading a tag here without overstating what it proves

A confirmed certificate and an applicability tag test different things even on the same profile: a certificate is audited against a management system or a specific service line, while the Security focus tag also requires a published case study alongside that certificate or a penetration-testing service. A tag built on a published case study can be checked against that case directly, which gives it a layer of verification a bare service listing lacks; a tag that rests only on a certificate or a delivery location carries no such example attached to it. A published case study, once found, answers a narrow question: it names one project and one measurable outcome specific to that engagement. None of the five tags on this page describes, by itself, how a vendor schedules test cycles against a client's release calendar day to day, and tooling and pricing remain unpublished across most of this set.

How this ranking was put together

Membership is computed from the profile, not chosen: companies appear here when they offer a continuous testing program as an engagement model, as their own profile states. Position in a ranking cannot be bought. Paid options are limited to the extended profile, labelled sponsor slots and lead forms, and none of them affect tags or order.

The table compares the fields that decide this axis: published rates, minimum project, onboarding, plus the number of verified reviews on external platforms. Rates, minimum project size and onboarding time carry the source they came from next to the value.

Nearshore for the EU: At least one delivery location in the EU or the EEA, or in Ukraine, Georgia, Serbia or Moldova.
Security focus: Security testing is offered, together with either penetration testing or a verified ISO/IEC 27001 certificate, and at least one published case study.
Nearshore for the USA: At least one delivery location in Canada, Mexico, Central America or South America.
Crowdtesting at scale: The crowdtesting engagement model is offered, and a published tester pool of 10,000 people or more, with a source.
Performance engineering: Performance testing is offered as a service, and at least one published case study reports a throughput or latency metric.

How to choose a vendor on this axis

Published by QA RatingPublished on September 3, 2026Updated on September 5, 2026

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.
