Ericom Web Application Isolation (WAI) is a clientless Zero Trust Network Access (ZTNA) solution designed to secure access to corporate web and SaaS applications from BYOD and unmanaged devices, such as contractor or employee-owned laptops and PCs. WAI routes unmanaged device connections through an isolated, secure cloud environment, where granular data and access controls are enforced. Users access applications via a standard web browser without requiring any client software installation. The solution is aimed at IT and security teams that need to extend application access to third-party contractors and BYOD users while minimizing the risk of data loss, malware injection, or unauthorized access. Key security controls applied within the isolation layer include: - Blocking file uploads and downloads - Sanitizing file uploads to prevent malware injection - Applying DLP policies to downloads to prevent data exfiltration - Restricting or disabling cut/copy/paste (clipboard) functions - Presenting applications in read-only mode to prevent text modification - Preventing app data from being cached on the unmanaged device's browser - Enforcing IP-based access control, permitting access only through WAI - Concealing web application source code, developer tools, and APIs from external probing WAI also addresses web application attack surface reduction by "cloaking" applications — hackers or malware probing for vulnerabilities see only a few lines of Ericom Remote Browser Isolation HTML instead of actual page source, developer tools, or API endpoints. The solution is documented to address the OWASP Top 10 Web Application Security Risks.
