Xint utilizes AI to collect and structure website information, then analyzes website vulnerabilities while interacting with people, offering advanced capabilities compared to existing tools.

Cybersecurity company Theori (CEO Park Se-jun) held a press conference at Oakwood COEX in Seoul on the 28th and officially launched its AI-based security service 'Xint' in Korea.

CEO Park Se-jun, who was in charge of the announcement that day, said, “Tiori is pursuing ‘offensive cybersecurity,’ which goes beyond the existing defensive security method and examines the system from the attacker’s perspective, as its core strategy.”

Founded in Austin, Texas, in 2016, Theory entered the global security market in earnest by establishing a Korean subsidiary in 2017. To date, we have provided security consulting to over 100 companies and organizations, collaborating with leading domestic companies such as Samsung Electronics, Naver, and Dunamu, as well as global tech companies such as Microsoft, Meta, and Google.

In May of this year, Theory's technological prowess was recognized by signing a strategic security partnership with global IDP company Okta. Theory's members are comprised of world-class white hat hackers and have won numerous awards at DEFCON, often referred to as the hacking Olympics.

'Xint', which was recently revealed, is an AI hacker developed by teaching AI the hacking techniques and thought processes that Theori has accumulated over the past 10 years.

CEO Park Se-jun said, “Unlike existing security tools that simply detect known vulnerabilities, Jint can detect even unpredictable attack scenarios by mimicking the thought processes of actual hackers.”

CEO Park Se-jun stated, “Through Jint, Theory aims to solve three core problems: △ growing digital assets and complex attack surfaces; △ speed and cost issues with existing inspection methods that take weeks or months; and △ an absolute shortage of security personnel.”

Jint's AI continuously performs inspections 24/7, suggesting attack scenarios and generating test code with human-level contextual understanding. This enables companies to maintain sustainable security operations.

In particular, Jint has the ability to understand and inspect business logic.

It goes beyond simple code bug detection and detects unauthorized access by understanding the service's operating methods and rules. AI navigates websites, uses features, and identifies vulnerabilities just like a real user.

Ease of implementation and stability are also key strengths of Jint. It's provided as a SaaS, allowing inspections via a URL without any separate installation or code changes.

This non-destructive inspection method does not affect the operating system, and has performed over 3,000 hours of inspections in over 200 domains to date without a single operational risk.

Zint offers overwhelming efficiency compared to existing security audit methods in terms of speed, cost, and sustainability. The average audit time is less than 12 hours, approximately 30 times faster than existing methods, and its subscription model allows for continuous audits at a reasonable budget.

Through Jint, Theory plans to expand beyond the domestic market and into the North American market. It has already established a development and sales team in the US and aims for full-scale expansion starting in 2026.

“Security is no longer an event, but an essential element that must be operated continuously,” said Park Se-jun, CEO of Tiori. “Jint will set a new standard for security by combining AI and human capabilities.”
