What is Cross-Site Scripting?

Cross-site scripting is the injection of undesired code onto a website, usually in the form of JavaScript. The attacks themselves occur when the unwanted code is not blocked and is permitted to run on the site. 

The attacker, such as Magecart, use their code to steal personal banking information, conduct damaging spam attacks claiming to be your consumer, or conduct other fraudulent and malicious activity in their name. 

XSS attacks can also allow attackers to spread malware and even edit website content, which often times can be used to spread false information or wreak general havoc. 

An effective way to stop hacking groups like Magecart from stealing your personal data and adversely impacting your website's information via cross-site scripting (XSS), is by implementing a Content Security Policy (CSP) on your website.

With a CSP, you can:

  • Control what third-parties have access to your personal data (credit cards, emails, etc.)
  • Stop malicious code from sending personal data to an unauthorized location
  • Be protected from cross-site scripting (XSS), formjacking, and browser-hijacking attacks

Blue Triangle's CSP Manager

We provide a quick, effective, and automated way to build and manage your CSP so you and your customers can stay protected. With Blue Triangle, you'll know the second any unauthorized third-party tries (but fails) to access your site.


Be Protected from Cross-Site Scripting (XSS) in Just 4 Simple Steps


Step 1

See who is accessing your website

We start off by identifying what third-parties and their domains have access to your website. See what pages each third-party has access to.


Step 2

Determine who is allowed on your website

Quickly create a whitelist of approved third-parties, as well as what type of files they are allowed to load.


Step 3

Auto-generate your Content Security Policy (CSP)

Using your whitelist, Blue Triangle automatically generates a comprehensive CSP that you can deploy in seconds.


Step 4

Deploy CSP and stay secure

Your CSP blocks any unknown or malicious domains from accessing your site. We’ll even notify you as soon as there are any violations to your CSP.

Not ready to block? Then stay in alert-only mode.
