CITY for Enterprise

We are looking for our first five or so partners.

Each company gets a dedicated AI agent that builds a CITY of the entire group. Within the first three months, it will be ready to review at executive meetings.

Who we are looking for

  • Companies and organizations whose IT spending exceeds about 50 million yen a year*
  • Top management makes the decisions and can drive the project from the top down (for example, manufacturers, retailers and service companies led by founders or owners, chains with many stores or sites, holding companies overseeing group companies, and local governments whose heads make the decisions)
  • To deliver results in the first three months, the executives and staff in charge can respond quickly with information and decisions
  • You can build CITY together with Teleport and deepen the knowledge gained along the way

*The scale is a guideline.

The state of cyberattacks

A single weak point can bring the business to a halt

  • 226Ransomware incidents reported to the National Police Agency in 2025
  • About 60%Share of affected companies and organizations that were small and medium-sized businesses
  • Over 50%Organizations that spent 10 million yen or more in total on recovery (survey of affected organizations)
  • Over 60%Share of intrusions through VPN devices (same survey)

Attackers get in through unpatched vulnerabilities, leaked credentials, weak passwords and misconfigurations. They then spread inside the network until they reach critical 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. Each weak point may be small, but it can reach the core of the business through the connections between systems.

Claude Mythos 5.1

We have adopted Claude Mythos for our research and development

Claude Mythos 5.1 is an AI model developed by Anthropic in the United States. It is exceptionally capable at finding and analyzing software vulnerabilities. Because it could be misused for attacks, Anthropic has not released it to the public and provides it only to users who have passed reviews such as its Cyber Verification Program. Teleport passed this review in November 2026 and uses the model for its own systems and for research and development of Data is CITY.

Data is CITY maps the connections across the whole company, while Claude Mythos 5.1 analyzes individual pieces in depth.
  • Thousands of severe vulnerabilities found

    Anthropic has announced that, using an early version of Mythos (Claude Mythos Preview), it found thousands of high-severity vulnerabilities across every major operating system and web browser.

  • The overall structure, and deep analysis of each part

    Data is CITY maps the connections across the whole company, and Mythos analyzes individual pieces of software in depth. Teleport is refining this combination on its own systems and in its research and development, and applies the knowledge and technology gained to Data is CITY.

About Data is CITY

A 3D map of your company's IT assets, updated every day

Websites, servers, cloud services, business systems, accounts and access rights. At many companies, these are managed separately by each department or vendor, and no one understands the overall configuration. Data is CITY describes them in a common data structure and visualizes them as a 3D city. AI agents update it every day, and executives and staff decide response priorities based on that screen. You can learn more through the following three items.

  2. 02How it was developedExplainer · by Tomoyasu Hirano (CEO)

    We inventoried five years of Teleport's own digital infrastructure and turned it into a 3D map

    1. After inventorying five years of digital infrastructure, we could account for only about 70%. The remaining 30% was unclear, and for about 10% we could not even tell what it was
    2. We described everything in a common format and uncovered it together with AI agents
    3. Even with the ledgers fully organized, no one could grasp the whole
    4. Drawn in 3D, the overall structure emerged from the data

AI agents

Gathering, updating and reporting information

  • Re-reads ledgers and settings every day and updates CITY
  • Gathers security information and reports whether the company needs to respond
  • Explains dependencies and the scope of impact, and proposes countermeasures

People

Decisions, execution and accountability

  • Executives, employees and engineers discuss while looking at the same screen
  • Decide response priorities
  • Carry out countermeasures and take responsibility for them

What we provide

From finding vulnerabilities to identifying the scope of impact and prioritizing the response

Finding a vulnerability alone does not prevent damage. Countermeasures move forward only once you know which of your systems are affected, which operations are impacted, and who should respond in what order. Data is CITY provides three foundations for this. All of them are operated by Teleport in-house and were actually used in our response to the PHP vulnerability in October 2026.

Diagram of the three foundations Data is CITY provides: discovery know-how, the CITY Dashboard and the CITY Agent
  1. 1

    Discovery know-how

    A procedure for uncovering a company's IT assets together with AI agents. Servers, accounts, credentials, domains and even where data is stored are organized according to CITY's common format.

  2. 2

    CITY Dashboard

    A screen that visualizes the organized information as a 3D city. From above you can check the overall configuration; zoomed in, individual systems. Executives and engineers can discuss on the same screen.

  3. 3

    CITY Agent

    An AI agent that updates CITY every day, explains dependencies and the scope of impact, and proposes countermeasures. People make the response decisions.

Our own track record

The October 2026 PHP vulnerability: scope of impact identified in about five minutes, response completed within 30 minutes

For the October 2026 PHP vulnerability, Teleport worked with an AI agent on its own CITY, identified the scope of impact on its systems and the necessary response in about five minutes, and completed the response within 30 minutes (according to our records). This was possible because, before the vulnerability was disclosed, we already had the full picture of our IT assets in CITY and had shared it with our AI agent.

FAQ

FAQ

QIs CITY still a concept, or is it under development?

It is not a concept. CITY has been running inside Teleport since August 2026. The CITY screens on this site are not mock-ups but screens from the live CITY (for publication, company information has been replaced with fictitious data). As shown in the film, you can check its status in real time, and you can move through the screen while talking with an AI agent to investigate problems.

QWho is CITY for?

There are already many visualization tools for system administrators and engineers. CITY aims for something else: enabling everyone in the organization, including executives, to understand their company's digital environment. CITY is always kept up to date, and a dedicated AI agent continuously checks and explains what is happening now and what it means.

QCan companies without dedicated staff use it?

CITY for Enterprise and CITY for Business have very different goals. In large organizations, multiple vendors and staff work in silos, and the challenge is that no one can grasp the company's digital environment as a whole. CITY for Enterprise aims to let executives take the lead, understand the whole through CITY, and direct the response. Meanwhile, many companies have no dedicated security staff. We are planning CITY for Business so that such companies can use it as well.

QWill CITY respond for us when we are hit by a cyberattack?

No. We draw a clear line here. Incident response after a breach is the domain of specialized security firms and is not something Teleport provides. As the film shows, attacks progress in seconds, and dealing with them after an intrusion is extremely difficult. In fact, human defenders cannot keep up, and data breaches continue.

That is why preparation in advance matters. What Teleport calls "AI-powered defense" means preparation before an attack. AI agents understand the company's digital environment and tell executives and decision-makers, ahead of time, where problems could arise and how to prepare. To begin with, many companies do not know what they have where, or where the risks lie. CITY makes that visible.

QHow do you deal with the data breaches and cyberattacks reported every day?

Data is CITY's AI agents learn from the breaches and attacks reported every day. Questions such as "Could yesterday's reported breach happen to us?" and "What would happen to us if we were hit by that attack?" are tested by the agent on CITY and reported to executives and staff.

QDoesn't gathering information in one place make it more dangerous?

On screens viewed by multiple people, confidential information is masked. Where the gathered information is stored, who can view it, and what permissions the AI agent is given are decided before use begins, in line with the company's rules and review criteria. We also consider a state in which information is scattered and no one has the full picture to be a risk in itself.

QDoes CITY run in the cloud?

CITY's basic principle is: "Keep the company's map inside the company." CITY handles the information most important to a company: how its digital environment is structured and what information it runs on. We do not intend to place or store this anywhere it would be exposed to risk.

For this reason, CITY for Enterprise runs, as a rule, in the company's own environment (on-premises servers or an environment the company manages). However, we believe the AI agent should use the latest and most capable AI models (frontier models). Only that part connects to the internet. What we pass to the AI model is the structural information needed for decisions. We do not pass confidential information itself, such as passwords or keys, because the AI does not need the contents of confidential information to make decisions.

CITY for Business will be offered as a cloud service, for ease of use and adoption.

QHow long does it take to get started?

What takes the most time is the initial information gathering, "discovery" (uncovering the IT assets). It varies by organization, but with full commitment, we expect a small organization to reach a full picture in one to two weeks, and even a large organization within three months.

QWhy only organizations that can move top-down?

Not every organization has three months to spare. With cyberattacks now an everyday occurrence, fast decisions and action are required. There is no room to spend time on coordination between departments and repeated discussions. That is why we work only with organizations that will tackle this issue with full commitment under the decision of top management.

QWhen will it be available?

CITY for Enterprise will start with our first five or so partners. For CITY for Business, we are accepting inquiries. Articles, manga and classroom slides for families and schools are published free of charge on Data is CITY Media (in Japanese).

QBesides CITY for Enterprise and CITY for Business, do you plan to offer anything for individuals?

For individuals, we first provide learning materials on Data is CITY Media on what each person should watch out for to prepare for cyberattacks, and on digital literacy in the AI-native era. Whether to launch a service for individuals is currently under consideration.

QHow much does it cost?

For CITY for Enterprise, even at the smallest scale, we expect an initial setup fee of 10 million yen and an annual fee of 10 million yen, or about 20 million yen in the first year, as a starting point. This is a guideline for the smallest case; we provide individual quotes based on the size of the organization and the scope. For CITY for Business, we are considering a monthly fee that is easy to afford.

Data is CITY PROJECT

Toward a society where people can understand and protect their own digital environments

Data is CITY is a project that supports security in the AI-native era through both technology anyone can use and media.

1

CITYWe are releasing open technology that visualizes digital environments

It visualizes the IT environments of companies, local governments, schools, hospitals, stores, homes and more in 3D, like a city map.

AI agents continuously investigate systems, networks, data, permissions and more, keeping the map always up to date. They also detect changes in the environment, security issues and potential dangers, and let you know.

So that anyone can use this mechanism freely, we will release CITY's common format and software.

2

Data is CITY MediaSecurity media for the AI era

We follow the front lines of cyberattack and defense in the AI era, with daily news, interviews with experts, experiment videos and live programs.

We are also planning online classes to build security literacy, games that simulate attack and defense, and participatory events.

Learn about the latest technologies and trends, deepen your understanding according to your interests, and put it into practice. It is media that helps everyone, from experts and executives to students and everyday users, make use of security in the AI era from their own standpoint.
