Malware analysis & file security

We expose the threats hiding inside your files.

Quasar Infinity turns the documents and files your business exchanges every day from a blind spot into a verdict you can trust — through multi-layer, multi-engine analysis combining static, dynamic, visual and AI techniques.

About us

Seniority you can build on.

Quasar Infinity is a young company headquartered in Japan, with a European subsidiary opening soon. It is built by people with more than 20 years of experience in cybersecurity, antivirus and malicious-code analysis.

That seniority comes with pragmatism: we stay flexible and adapt to each client's requirements rather than forcing a one-size-fits-all product. We are dedicated to the analysis and detection of malicious software, and to providing security and professional malware-analysis services to businesses.

  • 20+ years of front-line cybersecurity experience
  • 4 analysis layers: static · dynamic · visual · AI
  • Multi engine detection for consensus verdicts
  • 2018 refining our document engine since
“In the digital world, we don't build walls to hide from fear; we forge the shield that lets progress move forward without looking back.”
CEO, Quasar Infinity

Our vision

Documents are the blind spot. We built the engine to see them.

Our current focus — and our strongest suit — is document files. They are the most widely exchanged file type in modern business, yet they remain a blind spot that traditional antivirus vendors rarely address with the depth they deserve.

We built our engine to close exactly that gap, combining a multi-layer, multi-engine scanning system with static, dynamic, visual and AI analysis. And of course, we cover every other file type too.

Our values

The maximum security and privacy of our clients is our reason to exist.

Innovation

We don't wait for threats to define us. We research, prototype and ship new detection techniques so that tomorrow's attacks meet defenses that already understand them.

Puzzle solving

Every malicious file is a puzzle. Where others see noise, our analysts and engines see structure, intent and the single anomaly that gives an attacker away.

Trustworthiness

Security is a promise. We earn it with transparent verdicts, rigorous methodology and an uncompromising respect for our clients' data.

Our journey

From a single idea to a public platform.

  1. 2018

    The dynamic layer is born

    Our journey begins: the first dynamic-analysis layer for documents detonates files in a controlled environment to reveal behavior that signatures can't see.

  2. 2019

    Deep static inspection

    We add a static-analysis layer that dissects document structure to catch threats before they ever run.

  3. 2020

    Seeing the threat

    A visual-analysis layer joins the engine, and coverage expands to many more document formats.

  4. 2021

    Precision year

    A year focused entirely on accuracy — sharpening detection rates while driving false positives down.

  5. 2022

    Beyond documents

    Our coverage grows beyond documents to a far wider range of file types.

  6. 2023

    Multi-engine

    Additional analysis engines come online, strengthening every verdict through consensus.

  7. 2024

    The Web API

    The first version of our Web API opens the platform to programmatic, at-scale analysis.

  8. 2025

    Services & growth

    We expand our professional analysis services and formally establish the company.

  9. 2026

    Public release

    Pulsar goes public — the platform opens to the world.

“Real power on the internet is not hoarding all the information; it's the absolute certainty that no one can take it from you.”
CEO, Quasar Infinity
