Instart Web Skimming Protection

Zero-trust model for sensitive data protection

Deep browser-level controls to protect form fields and cookies from unauthorized JavaScript access.


Get control where you need it — in the browser

Modern web apps rely on JavaScript to bring enhanced functionality, but these scripts open them up to the possibility for attacks which target your customers’ PII. JavaScript, whether your own code or from a third-party, has complete access to a web page, meaning any script has the ability to skim sensitive data. Instart gives you control over which sensitive data JavaScript can access in the browser so your customer’s data stays safe and you avoid privacy violations.

Protect your customers’ sensitive data

Instart’s zero-trust model prevents access to your customers’ personal information by limiting all JavaScript access to HTML form fields and cookies, except for those which are explicitly allowed.

Insulate your website from exploited third-party code

If a third-party JavaScript has a vulnerability or is exploited by an attacker, such as Magecart, the security of your website is impacted. Instart prevents access to website data by any JavaScript except for those which are explicitly allowed.

Reduce your risk of GDPR and CCPA violations

Instart reduces the attack surface for data exfiltration and the subsequent issues associated with GDPR or CCPA by preventing unnecessary JavaScript access to form fields and cookies.

Common threats

Instart Web Skimming Protection prevents these types of attacks

Web skimming

Web skimming attacks, also known as e-skimming or data skimming attacks, happen when personally identifiable information (PII), either entered into a browser or stored in a cookie, is leaked to unauthorized third-parties.

Explore the threat

Magecart attacks

Magecart attacks, or digital payment card skimming, leverage JavaScript skimmers to listen for payment information as it is entered into a website by customers on a checkout page.

Explore the threat

XSS attacks

Cross-site scripting attacks are performed by injecting JavaScript into areas of a website where users can provide information, such as forums or comment boxes. These attacks are used to steal private data stored within cookies, coerce users into downloading malicious attachments, or tricking users into navigating to alternate versions of websites.
