Client-side Security Measures


Web Application Firewalls (WAF)

  • Can WAFs detect and protect businesses from sophisticated skimming malware?
  • Are WAFs able to detect manipulated JavaScript code or if data is being exfiltrated?
  • Do WAFs protect against sideloaded malicious code?

Content Security Policy (CSP)

  • How easy are CSPs to implement?
  • Are CSPs easy to maintain across multiple web applications?

Pentesting, Vulnerability Assessments and Security Assessments

  • Are quarterly pentests and assessments enough to stay ahead of client-side threats?
  • Can security tests and assessments be performed by my team on a regular basis to stop data exfiltration attacks?


Client-side JavaScript Vulnerability Scanning

  • Can traditional vulnerability scanners detect vulnerabilities client-side JavaScript web applications?
  • Are vulnerability scanners designed to detect client-side vulnerabilities that only appear when they are loaded in the user's browser?


JavaScript Security Permissions

  • Do JavaScript security permissions actually exist and how can they help me?
