Takumi by GMO: Revolutionizing Cybersecurity with Automatic Vulnerability Fixing

In a significant step towards enhancing software security, GMO Flatt Security has launched the "automatic fixing feature" for their security diagnostic AI agent, Takumi, effective February 5, 2026. This innovative feature allows Takumi to seamlessly detect vulnerabilities and generate patches, easing the workload for developers and fostering a more secure software development lifecycle without additional costs.

What is Takumi?

Takumi is an AI agent designed specifically for security tasks, developed by GMO Flatt Security. With unparalleled capabilities, it identifies vulnerabilities that traditional automated diagnostic tools might miss, such as authorization control flaws and logic vulnerabilities. Takumi supports both Black Box (DAST) and White Box (SAST) testing, providing flexibility tailored to various software development needs.

Understanding the Automatic Fixing Feature

This feature empowers Takumi to automatically generate patches for vulnerabilities detected during security assessments. Previously, engineering teams at client companies had to either fix vulnerabilities themselves or engage additional coding AI agents for assistance. Now, with the automatic fixing capability, the majority of the process can be managed by Takumi, requiring only a final review from human engineers.

Reasons for Development

The demand for faster and more efficient handling of vulnerabilities has surged due to improvements in AI's performance. Takumi stands out with an impressive 96.2% detection rate in benchmarks when tested on GMO Flatt Security's proprietary dataset. However, high detection rates also lead to increased labor in managing vulnerabilities, prompting the need for this automatic fixing feature to simplify the process while maintaining robustness.

Feature Highlights

1. Flexible Diagnostics: Both white and black box testing can seamlessly communicate with the automatic fixing feature. Engineers simply select identified vulnerabilities from a dropdown menu, choose their preferred output language (Japanese or English), and the repository to start generating fixes.

2. Multiple Updates for Fix Proposals: Users can request multiple iterations of the proposed fixes. Each proposal is displayed for users to review before creating a Pull Request (PR), allowing for precise control over the final output.

3. Automatic Unit Test Generation: Each fix proposal includes unit tests and a report justifying the changes, minimizing the review workload for engineers and ensuring the integrity of the software.

How to Use the Automatic Fixing Feature

From today, all Takumi users can access the automatic fixing feature without additional fees or changes to their plans. A user guide is available for those seeking detailed instructions on how to utilize this innovative tool effectively. Check out the User Guide here.

Feedback from Early Adopters

Here’s what some early users of the automatic fixing feature had to say:

• - Yoshihiro Ibayashi, CTO at Game8: “The automatic fixing feature not only identifies issues but also provides concrete actions, making it easy to integrate into existing workflows.”

• - Sugunyan Jo, Security Engineer at Hacomono: “This tool drastically reduces the time needed to come up with fixes, allowing us to focus on reviews and ensuring secure coding practices.”

• - Ryota Kitazawa, from Sansan's Product Security Group: “It even includes thorough integration tests, preventing vulnerabilities from recurring due to oversight.”

• - Yoshiharu Yamashita, Head of Engineering at Partner Prop: “The flexible diagnostic capabilities and the clarity it brings to proposals significantly speed up our processes.”

Future Directions

As part of their mission to support software developers, GMO Flatt Security will continue enhancing Takumi. They aim to empower developers to focus on innovation while ensuring robust security protocols are maintained.
