Browser Vulnerability Research Framework
SeekZero is a JavaScript engine vulnerability research framework built from methodology validated through real-world CVE discovery in V8, Blink, and WebCore.
It gives researchers programmable control over generation, mutation, execution, coverage feedback, and orchestration - enabling teams to develop their own unique and proprietary research workflows.

Turning Browser Research into a Framework: SeekZero
After proving the methodology in real-world browser targets, the Tashita research team evolved the process into SeekZero: a JavaScript engine vulnerability research framework built for advanced researcher-guided automation, scalable execution, and programmable research workflows through a REST API-first architecture.
Core capabilities
- Researcher-guided generation, mutation, and execution
- Custom mutation plans, targeting strategies, and priorities
- 1,500+ configurable research settings
- Interactive Playground with live execution and coverage visibility
- Distributed orchestration for scalable execution
- REST API-first automation and external integration
- Multi-user workflow and resource management
Why Teams Use SeekZero
- Avoid building complex research infrastructure from scratch
- Improve researcher productivity, visibility, and control
- Scale execution while preserving researcher-guided strategy
- Develop proprietary browser vulnerability research capabilities
- Support long-term, organization-specific research workflows
Built for Advanced Research Workflows
SeekZero enables researchers to guide, customize, and automate JavaScript engine vulnerability research through programmable execution workflows, real-time interaction, and scalable infrastructure.
Interactive Research Environment
Researchers can execute custom JavaScript samples, define mutation plans, observe coverage and execution paths in real time, and iteratively refine research strategies through the interactive Playground.
Programmable Research Workflows
A REST API-first architecture makes SeekZero scriptable, extensible, and easy to integrate with internal tooling, automation systems, and AI-assisted workflows.
Teams can build proprietary workflows tailored to their objectives, infrastructure, and expertise.
Unique Research
SeekZero is designed to support differentiated and proprietary research workflows rather than uniform automated execution.
Researchers can define mutation plans, targeting strategies, execution priorities, and orchestration logic while observing execution behavior and coverage feedback in real time.
Enterprise Infrastructure
SeekZero is designed for advanced security organizations operating browser vulnerability research workflows within controlled enterprise environments.
Local Deployment
Deploy SeekZero within controlled internal infrastructure and research environments.
Scalable Orchestration
Coordinate distributed execution workflows across synchronized research infrastructure.
Multi-User Research Framework
Manage users, resources, execution workflows, and research activity through a centralized framework.
SeekZero Onboarding
Access to SeekZero is currently limited to a select number of organizations.
Organization Evaluation
Prospective customers may undergo legal and operational due diligence before onboarding.
