Website vulnerability scanning

Scan the code and infrastructure that support your website for security vulnerabilities. 

Website security matters

Vulnerability management is a critical requirement for anyone running web applications or interactive and static websites. These public-facing assets are common attack vectors for malicious actors seeking unauthorized access to systems and data, so it’s important to make sure they’re secured properly with website security checks. You can scan website code and dependencies with Snyk in three steps:

1. Create an account

Create a Snyk account and connect your project repsitories.

2. Import a project

Import a project (or run a scan locally) to scan your website code and identify issues.

3. Review results

Review the scan results and make fixes to your website code based on the details of the issues found.

How does website vulnerability scanning work?

Web vulnerability scanners scan application/website code to find vulnerabilities that compromise the application/website itself or its back-end services.

These site scanners work against a known list of common exploits that use various injection and evasion techniques to “hijack” web applications and websites in order to exfiltrate data, to trick users or systems into providing sensitive information, or to disrupt application performance. Some of the better known exploits are SQL injection, cross-site scripting (XSS), man-in-the-middle (MITM) attack, and malicious code.
