A Virtual Private Network (VPN) is the best solution to allow remote employees secure access to company resources without interception concerns. A VPN establishes an encrypted tunnel over the internet, ensuring that data transferred between remote employees and the company is secure from eavesdropping. * Proxy server helps with web content filtering and anonymization but does not provide encrypted access. * NGFW (Next-Generation Firewall) enhances security but is not the primary tool for enabling remote access. * Security zone is a network segmentation technique but does not provide remote access capabilities.
