Connect Server

Built upon Aspera Enterprise Server technology, the Aspera Connect Server is the ideal solution when files and directories are exchanged with a large number of users over the WAN.

With patented FASP® transport at its core, the Aspera Connect Server delivers unmatched performance and includes all the exceptional transfer and user management capabilities of the industry-standard Enterprise Server.

Featuring a web-based directory listing that can be accessed from most standard browsers, the Aspera Connect Server lets authorized users upload and download data with a web browser. Connections with Enterprise Servers, Point-to-point, Desktop Client and Aspera's mobile applications are also supported.

Thanks to a set of rich APIs, the Aspera Connect Server can be embedded into any web application to serve as the high-speed backbone for transfers of file-based data over the public Internet or private IP links.

With the option to run in the cloud, Connect Server enables access to instantly scalable, on demand storage and computing capacity.

Use Cases

Global file exchange for large, distributed groups of users

Share and exchange files or entire directories of any size with users across the globe, over any distances or networks, with only a web browser required on users’ end.

Enterprise-wide file movement

Create a centralized, high-speed file repository that can be accessed via a browser, Aspera desktop clients, or custom applications using Aspera embedded client.

Field and third-party content or data gathering and distribution

Enable outside organizations to easily contribute or download digital content via secure, reliable, high-speed file transfers.

High-speed file transfer backbone behind web applications

Using Aspera’s rich APIs, easily enable high-speed file uploads and downloads for web applications such as digital asset management systems and media content portals.

Product Highlights

Fast, reliable transfers

Manually transfer files and directories or schedule repeating transfers. Allocate bandwidth based on transfer priority. Enable connections with a variety of client options including desktop applications, mobile apps, and third-party embedded clients. Provide worry-free experience with automatic retry-and-resume for failed transfers.

Scalable and efficient transfer environment

High-performance FASP transport supports thousands of concurrent transfer sessions and delivers solid throughput over high-loss and high-delay networks and maximizes utilization of allocated bandwidth on low capacity and on multi-gigabit networks.

Web enablement

Intuitive web-based interface creates a seamless user experience. Rich APIs make it easy to implement Aspera FASP transport within any web application.

Enterprise-grade security

Aspera FASP transport technology protects your vital digital assets with thorough SSH authentication, in-transit and at-rest encryption, and data integrity verification for each transmitted block.

Versatile administrative options

Server administrators can create user accounts with varied levels of access control, defining “root” directory, security requirements and bandwidth profiles. Admin-level users have access to real-time transfer monitoring, detailed reporting, and control over aggregate and per-flow transfer rate caps and prioritization.

File-based workflow automation

Create repeatable and scheduled transfers (one-time and recurring) using templates in Aspera Console.  Develop custom pre- and post-transfer processing with hot folders, scripts, web services and third-party embedded clients. Accept Aspera file transfer and automatically forward files to any other Aspera server.

Versatile File Transfers

Supports various options for transfer initiation, management and reporting

  • Transfer initiation from browser plug-in, Desktop and Point-to-Point Clients, command line, third-party embedded clients, or Mobile Uploader app
  • Guaranteed delivery times with “minimum transfer rate” configurable via transfer priority levels
  • High-availability cluster configuration options (active/active or active/passive) and reliable deliveries with automatic retry and resume of partial or failed transfers
  • Ability to name, track and report on any transfer with an optional transfer history database
  • Simultaneous multi-location file delivery using multi-point transfers
  • Automatic, fast and lossless inline compression reduces data set transfer sizes, providing further boost to Aspera's industry-leading transfer performance
  • Parallel/multi-host transfer feature enables mass data transfers to multiple computers in both cloud storage and on-premises compute clusters
  • Maximum control, even resource usage, and fastest transfer times with configurable options for controlling the intra-file 'splitting' over the parallel sessions

Browser Plug-in Client

Lightweight, self-installing plug-in compatible with most standard browsers

  • Automatic installation, upgrade and launching within the web browser
  • Browser-independent transfers let users continue working or close the browser while transfers take place in the background, without having to wait on a static web page for transfers to complete
  • Supports file, directory, and multi-item transfers, queues uploads and downloads, allowing user to override queue priorities and make on-the-fly rate control changes
  • Basic transfer bandwidth and progress reporting


  • Can be deployed in cloud infrastructure, taking advantage of unlimited storage and transfer scale-out and with optimized cloud I/O for maximum transfer speeds
  • Enables cloud-based deployments of Aspera faspex and Shares web applications
  • Easy deployment on Amazon Web Services, IBM Bluemix infrastructure, Microsoft Azure, Google Cloud Platform and other cloud platforms

Comprehensive Administration

Administrators have full control over user settings, can configure transfer parameters (preset and real-time), access real-time monitoring and control, and create custom reports

  • Create unlimited number of users, define access rights and transfer settings for each one, and enforce security settings based on organizational requirements
  • Set transfer priorities and define aggregate or per-flow bandwidth allocation; vary transfer settings based on time-of-day/day-of-week, per user or group, and by client IP address or metadata
  • Monitor all incoming and outgoing transfers in real-time; cancel, pause, resume or reorder transfers in the queue on the fly; configure email notifications and delivery confirmations on client and server

Fasp Proxy

Aspera's FASP Proxy enables secure high-speed transfers for client users within highly restrictive network environments.

“Before Aspera, we were only utilizing a fraction of our bandwidth, transferring at 40-50Mbps. Now that
we’ve deployed Aspera software, we consistently transfer at our maximum allocated rate of 300 Mbps,
fully utilizing the bandwidth, while protecting other critical traffic."Victor Felix, Senior Software Engineer at IGS
