What is the most efficient method for remote users to access a TCP-based application hosted on a private web server?

The most efficient method for remote users to access a TCP-based application hosted on a private web server is through Zero Trust Network Access (ZTNA) private access.

ZTNA operates on the principle of least privilege, which ensures that users are granted access only to the specific applications they need, rather than broad network access. This approach is particularly beneficial for securing remote connections because it mitigates the risks associated with users gaining unnecessary access to the entire network. With ZTNA, access to the private web server is tightly controlled, minimizing exposure and reducing the attack surface.

Additionally, unlike traditional VPNs, which may create a tunneled connection that grants access to the entire network, ZTNA provides application-level access while maintaining strict authentication and authorization policies. This makes it especially suitable for environments where security and compliance are paramount.

In contrast, while a Virtual Private Network (VPN) can offer secure remote access, it typically allows users broader access to the network rather than specific applications, which can increase security risks. Secure Web Gateways (SWG) focus on filtering web traffic and ensuring safe internet usage rather than specifically addressing secure access to private applications. Lastly, a Cloud Access Security Broker (CASB) provides security controls for cloud applications but is not
