Browser Extension Security
Browser extensions have access to cookies, passwords, session tokens, and page content. A single malicious extension can exfiltrate credentials, inject code, and hijack sessions across your entire workforce. Surface Security gives you complete visibility and control over every extension installed.
Extensions have the keys to your kingdom
The average enterprise user has 5+ browser extensions. Many request broad permissions: read all site data, access cookies, modify page content. Malicious extensions can harvest credentials, steal session tokens, inject ads, and exfiltrate data silently. Most security teams have no inventory of what is installed, let alone what those extensions are doing.
