Press release

Teleport is approved by Anthropic for access to Claude Mythos
Preparing for AI-driven cyberattacks with Mythos

Passed the review for Anthropic’s Cyber Verification Program, for which publicly announced cases in Japan remain limited. Teleport will put it to work in research and development for Data is CITY, which already runs in-house, and is recruiting five partners

Teleport Inc. (CEO: Tomoyasu Hirano), a startup that develops and puts AI agents to work, has passed the review for the Cyber Verification Program (CVP) offered by Anthropic, the U.S. AI developer, and has been approved for access to Claude Mythos 5.1, Anthropic’s most advanced AI model.

Mythos is an AI model with exceptional capabilities in finding and analyzing software vulnerabilities. Because those capabilities could become a weapon if used for attacks, Anthropic has held off on a general release and offers the model only to users who have passed reviews such as the CVP. Anthropic has announced that, using Claude Mythos Preview, an early version of Mythos, it found thousands of high-severity vulnerabilities, including ones in every major operating system and web browser. In Japan, Hitachi, Ltd. has announced that it confirmed that, for source code running to millions of lines, Mythos could build threat models in a matter of hours, work that previously took security specialists and developers weeks (July 2026).

So far, only a small number of companies in Japan have announced that they have been approved for access to Mythos. Teleport will use Mythos on its own systems and in research and development for Data is CITY, which already runs in-house. Building on the knowledge and technology gained there, Teleport will bring companies of every size a way to understand their digital environment together with AI agents and keep improving it.

Bringing the advanced analysis capabilities of Mythos to Data is CITY

With this approval, Teleport will put the advanced reasoning and analysis capabilities of Claude Mythos 5.1 to work on its own systems and in research and development for Data is CITY. By combining the structure of the entire digital environment that Data is CITY captures with Mythos’s in-depth analysis of individual software and systems, Teleport will identify compound security risks that were previously hard to find, and make its countermeasures more sophisticated.

Discovering a security vulnerability does not, on its own, prevent damage. Countermeasures move forward only once it is clear which of the company’s systems are affected, which operations are impacted, and who will respond, in what order. Through Data is CITY, which visualizes a company’s entire digital environment, and through developing AI agents that work in dialogue with people, Teleport is building a system that supports everything from discovering vulnerabilities to identifying their scope of impact and prioritizing the response.

Teleport is also developing technology in which multiple AI agents work together to provide continuous support, from investigating vulnerabilities to planning countermeasures and verifying the results of fixes. Through this research and development, Teleport will strengthen the technology foundation of Data is CITY and offer it in two plans that match how it is adopted: CITY for Enterprise, in which the environment of an entire group is built jointly under the direction of top management, and CITY for Business, which lets a company use its own environment as a service.

CITY for Enterprise: Teleport is recruiting about five initial partner companies

Teleport is recruiting about five initial partner companies for CITY for Enterprise, its offering for companies and organizations. For each partner company, a dedicated Teleport AI agent works with the customer’s staff to build the digital environment of the entire group as a CITY, Teleport’s own environment for security measures. Within the first three months, it is brought to a state that can be used in executive meetings, and after that, continuous improvement and the building of know-how proceed together. To work steadily with one company at a time, recruitment is limited to about five companies.

The three foundations Data is CITY provides: discovery know-how, the CITY Dashboard, and the CITY Agent
The three foundations CITY for Enterprise provides to partner companies: “discovery know-how” that identifies information on IT assets scattered across the company, the “CITY Dashboard” that visualizes the company’s entire configuration in 3D, and the “CITY Agent” that updates the environment every day, explains the scope of impact, and proposes countermeasures.

Who can apply

  • Companies and organizations whose IT spending exceeds JPY 50 million a year*
  • Top management makes the decisions itself and can drive the work top-down (e.g., manufacturing, retail, and service companies led by founders or owners; chains with many stores or sites; holding companies overseeing group companies; local governments whose mayor or governor makes the decisions directly)
  • To deliver results in the first three months, the internal lead and staff can respond quickly with information and decisions
  • Willing to build a CITY together with Teleport and deepen the knowledge gained from it together

*The size is a guideline.

About Data is CITY: a system in which people and AI agents understand a company’s digital environment and keep improving it

Teleport runs its own digital environment on CITY. Developed in-house by Teleport, CITY is a technology that organizes a company’s digital infrastructure across vendor and system boundaries and visualizes it as a 3D city. It manages the relationships among servers, networks, databases, accounts, access permissions, and more in a common data structure.

The CITY screen. A company’s digital environment is drawn as a single city
The CITY screen. Clouds, servers, accounts, domains, and more are shown as districts and buildings, and lines show how they depend on one another (the screen is an example using information from a fictional company).

On CITY, AI agents developed in-house by Teleport continuously investigate the digital environment, keeping track of how the systems are structured, what role each plays, and how they relate to one another. Executives and employees can talk with the AI agents directly and get answers to questions such as these:

  • What role does this server play?
  • If this system goes down, which operations are affected?
  • Where should we start making improvements?

The AI agents explain based on actual system information and propose improvements. People understand what they hear, make the decisions, and carry out the improvements together with the AI agents. CITY is not just a tool for visualizing IT environments. It is a system in which people and AI agents understand the environment from the same information and keep updating it through dialogue. Beyond security, it supports improvements across a company’s entire digital environment, including IT asset management, understanding operating costs, and organizing systems.

In-house track record: for a PHP vulnerability, the scope of impact was identified in about five minutes and the response completed within 30 minutes

For the PHP vulnerability disclosed in October 2026, Teleport, through dialogue with its AI agents, identified the scope of impact on its own systems and the response needed in about five minutes, and completed the response within 30 minutes.

The three places where PHP is running, the owner of each, and the person who decides which to fix first, shown on the CITY
From the film “Protecting your company with people and AI agents” (8 min 40 sec). At the moment the PHP vulnerability is disclosed, CITY already shows where PHP is running, who manages each instance, and who decides what to address first (the company in the film is an illustrative example).

This response was possible because Teleport already had the full picture of its digital environment and had shared that information with its AI agents before the vulnerability was disclosed. Rather than starting to investigate after a problem occurs, Data is CITY lets you keep track of your environment in normal times and keep improving it. That is one of its key strengths.

Background: small weaknesses, through the connections between systems, can bring a business to a halt

According to Japan’s National Police Agency, 226 ransomware incidents were reported in 2025, and about 60% of the affected companies and organizations were small and medium-sized businesses. In a survey of affected organizations, more than half said recovery cost them JPY 10 million or more in total.

In the same survey, VPN devices accounted for more than 60% of intrusion routes. Attackers get in by exploiting unpatched vulnerabilities, leaked credentials and weak passwords, misconfigurations, and the like, then expand the compromise inside the network and reach important data and backups. In September 2025, a major beverage maker’s data center was breached via network equipment within its group, halting product orders and shipments (National Police Agency, “Threats in Cyberspace in 2025” (in Japanese, March 2026)).

Each weakness may be small on its own, but through the connections between systems, it can affect the core of the business. As advanced AI spreads to attackers as well, the time it takes for a weakness to be found and exploited is likely to become even shorter. Meanwhile, in many companies, websites, servers, cloud services, business systems, and more are managed by different departments and vendors, and no one has an integrated view of how they connect and depend on one another. When a problem occurs, investigating the scope of impact and deciding on countermeasures takes time. Teleport is developing a system that treats a fragmented digital environment as a single common structure that people and AI agents can understand and improve together.

Comment from Tomoyasu Hirano, CEO

“The further digitalization goes, the less executives can grasp the full picture of their own company’s systems. I don’t think that is how it should be.

“In a factory or a store, executives go to the floor, talk with the people who work there, understand the problems, and make improvements. But the digital space alone is left entirely to specialists and vendors, and executives themselves no longer know what is going on. Before it is a security problem, this is a management problem.

“What Teleport wants to change with Data is CITY is this structure itself. People and AI agents understanding the same ground, talking with each other, and improving it day by day. We will turn the digital environment into a place where executives and employees can take an active part.

“This approval is a major step toward making that happen. We want to take the world’s most advanced knowledge and technology that we gain here to companies and local communities all over Japan, whatever their size.”

Comment from Tsubasa Kawakami, CTO and Security Lead

“With the arrival of AI, attackers can now probe companies’ systems at scale in a short time. A small misconfiguration, a permissions gap, or outdated software may each be minor on its own, but combined, they become a way in.

“Data is CITY draws the full picture of how a company’s sites, servers, accounts, and permissions are connected. Claude Mythos 5.1 has the ability to dig deep into a single piece of software or an app within that picture, and to verify whether a vulnerability can actually be exploited. Connections across the whole, and the depth to dig into a single point. By combining the two, we aim to find the paths from small weaknesses to important data before attackers do.

“From investigation to planning a response and checking afterward, multiple AI agents work together and do it again and again. We will make it possible to carry out advanced security work, which used to take specialists a great deal of time, faster and on a continuous basis.

“We will make this approval an opportunity to take the technology foundation of Data is CITY a big step forward.”
