AXFILTER 2.0 Earns GS Certification Grade 1 from KTR
Jiransecurity said its generative AI data-leak prevention tool inspects prompts before they are sent. First deployments are planned at two institutions.
Jiransecurity announced on October 27, 2026, that its generative AI data-leak prevention solution AXFILTER 2.0 has obtained Good Software (GS) Certification grade 1. The testing and certification was carried out by the Korea Testing & Research Institute (KTR), according to datanet.co.kr.
AXFILTER 2.0 inspects prompts that employees enter into generative AI services before they are sent, and masks or blocks personal and sensitive information according to security policy. Resident registration numbers and other personal information are set as default detection targets.
The solution supports major generative AI services including ChatGPT, Claude, Gemini, GitHub Copilot and Perplexity. It offers per-service allow or block of access and per-department usage time settings. When a transmission is blocked, users see a notification message designated by the organization and can edit and resend.
Prompt usage history, detection reasons and actions taken are stored on a server, with the original text viewable only by authorized administrators.
Jiransecurity plans to supply and install AXFILTER 2.0 first at Daejin University and the Korea Labor Force Development Institute for the Aged. The company intends to complete procurement registration within the year ahead of the official launch, and said it will provide mapping reports linking security requirements to product features on customer request.
Earlier guidance for public institutions
In December 2025, the National Intelligence Service distributed an "AI security guidebook" to public institutions, and the Personal Information Protection Commission selected "insider security" as a themed indicator for the 2026 public institution personal information protection level evaluation.
