Gusto, a payroll and HR platform serving over 200,000 customers, has observed a concerning shift in cyberattacks from server-side vulnerabilities to client-side threats, as highlighted by their Chief Security Officer, Frederick "Flee" Lee.

Despite the rising threat, client-side security is often overlooked by organizations that primarily focus on server-side protection.

This oversight is particularly dangerous, as user browsers download and execute code every time they visit a website, making them highly susceptible to attacks.

One significant threat is e-skimming, where malicious code steals credit card information in real-time during online transactions.

Another tactic used by attackers is formjacking, which captures sensitive information submitted through web forms, including usernames and passwords.

JavaScript injection further complicates the issue, allowing attackers to insert harmful scripts into websites, thereby compromising user accounts and sensitive data.

To combat these risks, organizations should evaluate their exposure by tracking all scripts running on their site and proactively scanning for JavaScript vulnerabilities.

Addressing client-side vulnerabilities promptly is crucial to preventing significant business repercussions and protecting customer data.

Tools like Feroot Inspector provide automated protection, enabling organizations to manage vulnerabilities effectively and stay ahead of potential threats.

Automated tools are essential for efficiently managing vulnerabilities and reducing human error in security processes.

Leading organizations, including Gusto, utilize tools such as Feroot Inspector for comprehensive script monitoring and vulnerability detection.

To convince stakeholders of the importance of client-side security, it is vital to quantify risks, share real-world examples, and illustrate the personal impact on customer trust.
