In the ever-evolving landscape of cybersecurity, accurate vulnerability assessment is not just important, it's critical. Security teams, penetration testers, and analysts rely on the Common Vulnerability Scoring System (CVSS) to quantify the severity of security vulnerabilities and prioritize remediation efforts. However, traditional CVSS calculators often fall short in terms of user experience, accessibility, and modern features. That's where Cyberpath Quant comes in.
Today, we're excited to introduce Cyberpath Quant, a next-generation CVSS calculator that transforms vulnerability severity assessment into an intuitive, efficient, and powerful experience. Whether you're a seasoned security professional or just starting your journey in cybersecurity, Quant provides the tools you need to accurately assess vulnerabilities with confidence.
The Challenge with Traditional CVSS Calculators
If you've ever used a CVSS calculator, you know the pain points all too well. Traditional calculators often suffer from clunky interfaces that make metric selection tedious and error-prone, especially when metric descriptions are buried behind confusing labeling. Many calculators support only one or two CVSS versions, forcing security professionals to juggle multiple tools when working with diverse vulnerability databases or legacy systems.
Mobile experiences are often an afterthought, delivering frustrating interfaces that don't adapt to smaller screens. Export functionality is minimal or nonexistent, requiring analysts to manually copy scores and vectors into documentation systems. There's no history tracking, so previous assessments are lost, forcing teams to re-assess similar vulnerabilities from scratch. Perhaps most concerning, many traditional calculators process data server-side, raising legitimate privacy questions about where your vulnerability data is stored and who has access to it.
These limitations slow down vulnerability assessment workflows and create friction in security operations. When every second counts in identifying and remediating threats, your tools shouldn't be a bottleneck.
Introducing Cyberpath Quant: Built for Modern Security Teams
Quant was designed from the ground up to address these challenges and deliver a CVSS calculator that security professionals actually want to use. Built by Ebalo with a focus on user experience, performance, and privacy, Quant brings vulnerability assessment into the modern era.
Universal CVSS Version Support
One of Quant's standout features is its comprehensive support for all CVSS versions in a single, unified interface. Whether you're working with the latest CVSS v4.0 standard with its enhanced scoring methodology and supplemental metrics, the industry-standard v3.1 that enjoys broad adoption across the security community, the original v3.0 specification, or even legacy v2.0 data from older vulnerability databases, Quant handles them all seamlessly.
Switch between versions using intuitive tabs, allowing you to compare scores across different CVSS standards or work with legacy vulnerability data without ever leaving the tool. Need to check how a vulnerability scores under v4.0 versus v3.1? Simply toggle between tabs and see both assessments side-by-side. This universal support ensures that no matter which CVSS version your organization standardizes on, which vulnerability database you're referencing, or how diverse your assessment needs are, Quant has you covered.
Intelligent, Real-Time Scoring
Quant's scoring engine operates entirely in your browser using pure JavaScript, delivering instant feedback as you adjust metrics. Watch your CVSS score update in real-time as you configure vulnerability parameters, with dynamic color-coded severity indicators that instantly communicate risk levels.
This visual feedback system transforms abstract numbers into immediately understandable risk levels, helping security teams quickly triage vulnerabilities and prioritize remediation efforts without getting lost in numerical scores. The color-coding works intuitively across different CVSS versions, ensuring consistent communication of risk regardless of which scoring standard you're using.
Advanced Metric Configuration
Understanding CVSS metrics is crucial for accurate vulnerability assessment. Quant makes this process intuitive by providing interactive metric selection with clear, accessible controls for all metric groups. Rather than forcing you to memorize metric meanings or hunt through documentation, Quant includes in-context help explaining each metric's meaning and scoring implications directly in the interface.
The calculator provides full support for temporal and environmental metrics across all CVSS versions, and if you're using CVSS v4.0, it includes supplemental metrics like Safety, Automatable, and Recovery. Each metric comes with comprehensive documentation accessible directly from the calculator interface, complete with detailed explanations that help you understand how each selection impacts the final score. This educational approach ensures you make informed decisions when assessing vulnerabilities rather than blindly clicking through options.
Powerful Features That Set Quant Apart
Beyond basic scoring capabilities, Quant includes advanced features that streamline vulnerability assessment workflows and integrate seamlessly into your existing security operations.
Score Management and Analytics
Quant's Score Manager transforms how you track and analyze vulnerability assessments. Save your assessments directly in your browser for future reference, then organize them with powerful sorting and filtering by severity, date, CVSS version, or custom tags. Need to compare two similar vulnerabilities to understand why they scored differently? The side-by-side comparison feature shows you exactly where they differ. As new information about a vulnerability emerges, you can edit and update previous assessments without losing the originals, and if needed, restore deleted assessments from your complete history.
The Score Manager operates entirely client-side, ensuring your vulnerability data never leaves your browser while providing enterprise-grade organizational capabilities. Think of it as a personal vulnerability research database that travels with you, always available, always private.
Visual Analytics and Charts
Transform raw CVSS data into actionable insights with Quant's built-in analytics engine. Generate severity distribution charts showing how your organization's vulnerabilities spread across risk levels, helping you understand your overall vulnerability landscape at a glance. Metric impact analysis visualizations show you which factors contribute most to your scores, essential information when deciding whether to focus on remediating environmental factors or addressing core vulnerabilities.
Compare scores across different CVSS versions to see how a vulnerability's severity assessment changes depending on which scoring standard you apply. Interactive visualizations with customizable chart types and color schemes let you tailor the output to your needs, and when it's time to report to stakeholders, simply export your charts as PNG images for immediate inclusion in presentations and reports.
These visualization tools help security teams communicate vulnerability risk to stakeholders who may not be familiar with technical CVSS metrics, making it easier to secure resources and buy-in for remediation efforts.
One-Click Export and Sharing
Quant makes it effortless to document and share vulnerability assessments in whatever format your workflow requires. Copy vector strings with a single click for quick documentation in tickets, reports, or vulnerability databases. When you want colleagues to review your assessment or continue your work, generate shareable links with pre-configured metrics that others can open and review or even edit further.
For teams building custom security dashboards or integrating vulnerability data into their websites, Quant generates embeddable HTML code that brings interactive score cards directly into your applications. Need to move your assessment history between devices or back up your work? Import and export your complete history as JSON. The URL-based vector loading system is surprisingly powerful too, you can share exact assessments via simple links, making it easy to discuss specific scores with team members or document decisions in issue trackers.
Privacy-First Architecture
In an era of increasing privacy concerns and data breaches, Quant takes a privacy-first approach to vulnerability assessment that sets it apart from traditional online calculators.
