Presto File Server
SITA technology
Synology Internet Transfer Accelerator (SITA) is a transfer acceleration technology developed by Synology. It improves file transfer performance and conquers high-latency and unstable connections when transferring files over long distances.

-
Unleash the potential of your bandwidth
Stagnation caused by network latency leaves available bandwidth idle. By improving the packet delivery assurance mechanism adopted by FTP and HTTP, SITA reduces stagnation and fully takes advantage of the available bandwidth. -
Configurable transfer speed
With SITA, users can configure the minimum and maximum bandwidth according to their needs, better predicting and controlling the required file transfer time for different tasks.

Transfer digital data at high speed
Secure data transfer
Presto File Server transfers files at a high speed, without compromising the security of your login credentials or data.
-
Credential encryption and 2-step verification
-
Login credentials are secured in a dedicated TLS/TCP encrypted channel. The 2-step verification protects your credentials from attacks by malicious third parties and viruses.
-
File transfer encryption
-
Presto’s desktop client supports AES-128 encryption, ensuring bulk data remain highly secured as they transfer.
-
SSL verification
-
Synology Presto Client includes SSL verification to prevent users from connecting to phishing sites with untrusted SSL certificates, keeping the connection secure and safeguarding sensitive data.
Intuitive client for instant and automated transfer
The intuitive Synology Presto Client enables users to rapidly exchange data on all major operating systems anytime they wish, including Windows, macOS, and Linux. You can now use Presto through a command-line interface (CLI) based on the customized script that best fits your usage scenario.
Rapid, automated NAS-to-NAS file transfer
Transferring large files between multiple sites can take a long time, but for Synology NAS devices, you can schedule high-speed transfers across multiple sites with Synology Presto's Site Express. It automates file distribution by triggering the file transfer from one NAS to another, and its visualized interface allows you to view the current transfer status at a glance.

Flexible resource management
Synology Presto Client serves as an optimal solution for exchanging files between your PC and Synology NAS.
Dispatch and monitor resources
Priority of transfer tasks can be adjusted in Task Manager. Admins can keep track of events of different accounts on different servers through activity logs. Admins can also set the limitation on the number of concurrent file transfers to ensure the bandwidth is fully utilized by the prioritized tasks.
Flexible bandwidth control
Bandwidth can be adjusted directly on Synology Presto Client according to what's needed on-premises. Setting the maximum and minimum bandwidth thresholds for file transfers allows better prediction of the required transfer time and bandwidth resource management.
Smart compression
Synology Presto Client can adapt to different data types and environments. The data compression function will be disabled to save CPU resources during incompressible data transfers.
Automating high-speed transfer
You can automate the high-speed transfer according to your needs with the command-line interface support and desktop tool — Synology Presto Automator1.
