Security responsibilities are shifted to other companies to shoulder, which belittles some disadvantages like high cost and low flexibility.

Flexible service provision and SECaaS service providers' extensive knowledge and high efficiency lead to a higher service flexibility and continuity.

Security software standardization makes SaaS outsourcing infeasible.

SaaS applications, excluding antimalware software and anti-spam applications, are sophisticated in many fields and can be used widely.

The group management of computing nodes classifies computing nodes with the same configuration policy to the same device group.

eSight detects and limits the resource usage of different computing nodes, ensuring the resource uniqueness.

A computing node can belong to either a device set or a device group.

A group can be associated with multiple group profiles. The member profile of a computing node is generated based on the group profile.

To create a snapshot, the current disk is set to read-only. The system automatically creates an incremental disk in the data store where the disk locates.

An incremental disk records the differences between the current state of the disk and the state of the disk in the last snapshot.

Multiple snapshots can be created for one VM. If a VM is being restored using a snapshot, other snapshots of the VM are not affected.

Snapshots can be automatically deleted.

System security ensures proper running of the operating system, database, and middleware.

Network security includes transmission security and firewall security protection.

Data security includes the storage, transmission, and management security of user identity information, system configurations, run logs, and database data

The security mechanism is provided from the user, application, and audit perspectives, ensuring the O&M security.

eSight supports the hierarchical deployment, relieving the management pressure of large-scale networks.

Hierarchical deployment of eSight includes upper-level eSight and lower-level eSight.

Hierarchical deployment of eSight breaks through the resource management capability and performance limitation of single eSight site.

In hierarchical deployment of eSight, the version of the upper-level eSight can be different from that of the lower-level eSight.

If one physical machine is virtualized into multiple VMs, the physical machine is a host machine, and the VMs are guest machines. The OS installed on the physical machine is the host OS, and that installed on the VMs is the guest OS.

Through virtualization by the virtualization layer, upper-layer software regards the VM as a real machine. The virtualization layer is called VMM (virtual machine monitor) or hypervisor.

OS virtualization does not have an independent hypervisor layer, and servers and clients can have different OSs.

Bare-metal virtualization is a VM monitoring program running on physical hardware.

Both file-level and image-level migration are supported.

Resumable transfer is not supported.

The multi-data-synchronization function ensures data consistency.
