Which security technology can provide secure network communications from on-site enterprise systems to a cloud platform?

Internet protocol security (IPSec) virtual private network (VPN) is the technology that provides secure network communications from on-site enterprise systems to a cloud platform. IPSec operates at the network layer and is designed to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet in a communication session.

When on-site systems need to communicate with cloud services securely, a VPN creates a private tunnel over the public internet. This means that data transferred between the enterprise's systems and the cloud is encrypted, preventing unauthorized access and ensuring data integrity as it travels between two networks.

In contrast, other technologies listed do not primarily serve this purpose. For instance, DNSSEC is aimed at securing the DNS lookup process but does not encrypt network traffic. A Web Application Firewall (WAF) focuses on monitoring and filtering HTTP traffic to and from a web application, thus protecting web applications rather than securing general network communications. Data Loss Prevention (DLP) refers to a strategy to prevent sensitive data from being lost, misused, or accessed by authorized users, rather than creating secure channels for network communication.

Therefore, the use of IPSec VPN is essential for establishing a secure and encrypted communication link between on-site enterprise systems and cloud platforms, making it the
