Why Clients Choose Us

Extensive Experience and Broad Domain Knowledge

Leveraging Our Vast Defect Knowledge to Identify Critical Issues First
Through extensive testing across a wide range of web services, we have built a database of defect patterns. Because we understand browser‑specific behaviors, form input error tendencies, payment integration pitfalls, and other issues commonly seen in web services, we efficiently minimize risk even within limited testing time.

ISTQB Partner

Elevating the Quality of Your Web Services with Globally Recognized Testing Techniques
As an official partner of the International Software Testing Qualifications Board (ISTQB), we build structured and systematic verification processes. By applying scientific test‑design methods rather than relying on individual intuition, we detect complex web‑system logic issues, broken links, layout inconsistencies, and other defects with high accuracy, ensuring strong reliability.

High Adaptability and Customization

Designing an Optimal Verification Framework Tailored to Your Project’s Specific Challenges
We build fully customized test plans aligned with your quality issues and development structure. Whether you need targeted support, such as focusing on specific browsers or requesting only pre‑release regression testing, or full outsourcing from test design to execution, we provide the most suitable solution for your situation.

Service Overview

As an IV&V company, we cover the full lifecycle of web service testing—from test planning and analysis to design, implementation, and execution. We can also support individual phases only, such as test execution, depending on your needs.

Agile Testing
We provide specialized support for software testing in agile development environments. Drawing on extensive experience and proven expertise, we develop test plans optimized for your development process and help you deliver high‑quality software with confidence.

Functional Testing
Functional Testing is a type of testing that verifies whether software correctly executes its functions according to the specifications. It focuses primarily on “what” the system does and checks its behavior from the user’s perspective.
Our functional testing service thoroughly verifies whether your systems and services function exactly as expected, ensuring they behave in line with the intended specifications and user expectations.

Usability Testing
We deeply examine how easy your website, application, or software is for real users to operate. By adopting the perspective of your target users, we evaluate ease of operation, clarity, efficiency, and overall satisfaction from multiple angles. Based on these insights, we provide actionable recommendations that enhance the user experience (UX) and contribute to stronger business outcomes.

Platform Testing
We propose the appropriate combination of devices aligned with your product strategy. By covering device dependencies, OS and version differences, and screen‑resolution variations, we perform comprehensive testing that ensures broad coverage.

Load Testing & Performance Testing
We test actual load and performance conditions, such as response time and concurrent user volume, to identify performance bottlenecks.

Security Assessment
Partnering with GMO Cybersecurity by Ierae, Inc., a leader in vulnerability assessment with world‑class analysis technology, we provide hybrid assessments combining manual and tool‑based methods for Android apps, iOS apps, web applications, networks, IoT devices, and more.
By integrating product verification and vulnerability assessment into a seamless process, we centralize information management while ensuring superior quality and enhanced security levels concurrently.

Test Automation
To ensure mobile application quality after release, we continuously verify whether it functions correctly through automated testing.
