Deploy a traditional VPN solution, which, despite its higher operational complexity and cost, provides a well-understood method for secure remote access.

Implement a reverse proxy solution, which offers secure access from the internet but may introduce additional latency and does not inherently reduce operational complexity.

Use Microsoft Entra Private Access, which provides secure, seamless access to on-premises applications for remote users without the need for a traditional VPN, aligning with the organization's requirements for security, scalability, and cost reduction.

Configure the existing network infrastructure to allow direct access to on-premises applications from remote locations without implementing any additional security measures, compromising on security and compliance.
