API and Web App Discovery and Vulnerability Testing

As your organization’s portfolio of APIs and Web Apps grows by the day, it’s hard to keep track of them.
Probely provides an inventory of your assets so you can probe your company’s external attack surface for vulnerabilities.
Probely’s scanner finds and exposes vulnerabilities, and provides a report of the findings with detailed instructions on how to fix them.

Asset Discovery

You can’t protect what you don’t know. Probely helps you continuously discover, manage, and prioritize your inventory of APIs and web apps, so that your attack surface can be tested for vulnerabilities.

API Vulnerability Scanning

Scan both your rich web applications and APIs, including any microservices and standalone APIs that are based on an OpenAPI (Swagger) Specification or Postman Collection.

Next-Generation Spider

Probely’s revolutionary spider, based on Headless-Chrome, crawls and indexes your rich, interactive JavaScript apps and sophisticated Single-Page Applications with ease.

DevSecOps Focused

Developers and DevOps engineers value autonomous security testing. Probely offers a full-featured and well-documented API, and also provides two-way sync with your preferred issue trackers.

Evidence-based Reporting

Time is extremely valuable for both development and security teams. Probely provides context and proof of all relevant findings, with precise guidance on how to fix vulnerabilities.


Demonstrate your compliance with PCI-DSS, OWASP TOP 10, ISO27001, HIPAA, and GDPR standards using a series of detailed management reports with requirements checklists and summaries.

Cyber attacks are becoming more and more frequent and complex, which is why cybersecurity has been a growing business concern.

Probely helps us secure our web applications without compromising our project deadlines. We are able to start testing security in early stages of development, avoiding problems later, when the cost to fix is higher.

Our developers love Probely because of the easy instructions on how to fix the vulnerabilities and because it only reports what matters, false-positive free.
