# Vyshytech Inc. (合同会社Vyshytech)

> Cybersecurity and defense-technology company based in Ebisu, Tokyo, Japan.

## Name origin
"VyshyTech" = Vyshyvanka (Ukrainian embroidered shirt, traditionally worn as a protective charm with embroidery placed at the body's vulnerable points — neck, cuffs, shoulders, hems) + Technology. It symbolizes the company's stance of "protecting the weak points," and delivering technology that respects and gently embraces human culture rather than threatening it.

## Business areas
### Cyber Security
- Penetration testing: 90%+ vulnerability detection rate at significantly lower cost. Japanese white-hat hackers with government experience explain findings; hackers from heavily-attacked nations reproduce the latest attack techniques.
- Labyrinth Deception Platform (security software reseller): Ukrainian deception-based threat detection. Lures intruders into lifelike honeypots to detect and isolate them. <1% false positives; detection/response time (MTTD/MTTR) cut by up to 12x; ~30% lower operating cost. Used by financial and national institutions.
- White-hacker training: courses by active cybersecurity instructors; a Japanese-language program is in production.

### Defense Tech (disclosed at overview level only)
- Next-generation drones & robotics: combat-proven tech built around "low cost, mass deployment, China-free, swarm"; cost asymmetry.
- Combat training simulation: train in realistic conditions without consuming real equipment; data shows 50%+ improvement in soldier success rate; less affected by regulation, suited to early adoption.
- Defense-grade cyber: deception (Labyrinth), cryptography & IFF (identification friend or foe), offensive security; track record with NATO-affiliated institutions.
- Adoption roadmap in 3 phases: (1) software & training first, (2) domestic PoC, (3) domestic co-production — staged to reduce risk.

### Offshore Development
- Web services, systems, and blockchain development, leveraging a network built with Ukraine since before the war.

## Key metrics
- Penetration-test vulnerability detection rate: 90%+
- Labyrinth false-positive rate: <1%
- Detection/response time reduction: up to 12x (MTTD/MTTR)
- Labyrinth operating-cost reduction: ~30%
- Training success-rate improvement: 50%+

## Differentiators
- Access to combat-proven technologies refined in real combat.
- A partner handling technology transfer, localization for Japan, and domestic co-production — not a mere import agent.
- Holds both offensive and defensive perspectives.
- A long-standing relationship with Ukraine predating the 2022 invasion.
- On-the-ground Ukrainian partners who are fluent in Japanese and highly skilled in systems/technology — comrades who have worked together on many projects since before the war, enabling seamless collaboration across language, culture, and technical barriers.
