Aperture is deployed as a standalone service and requires which of the following?

Aperture, as a cloud-based security service, specifically requires a software agent on mobile devices to actively monitor and protect data. This deployment method allows the service to enforce security policies directly on endpoint devices, ensuring that data security measures are maintained regardless of the device's location.

The software agent facilitates continuous monitoring and the ability to implement security controls such as data loss prevention, protecting sensitive information as it is accessed or shared among users. This capability is essential for maintaining visibility and enforcement of security policies in real time on various mobile platforms, thus safeguarding corporate data while allowing for mobility.

Other options do not apply to Aperture's standalone service requirements in the same manner. For instance, hardware installation is unnecessary since Aperture operates as a cloud solution, and full network redundancy is more applicable to network infrastructure setups than a cloud service. Additionally, integration with on-premise servers is not a prerequisite for Aperture, which is designed to function independently as a SaaS offering.
