Stingray File Transfer Server

StingRay file transfer server, previously Hermstedt StingRay file transfer server, has now been made End of Life after 17 years of service, originally being released in 2001.

Frequently Asked Questions:

  • What’s happening to StingRay?

The way in which the StingRay software was initially written means it is limited to specific hardware appliance builds.  We are now unable to source servers of the same specification so have taken the decision to discontinue StingRay.

StingRay has been lacking many features that businesses have wanted for some time, this has resulted in Pro2col working with a variety of other file transfer vendors since 2008. Today we supply a range of solutions which have a far wider set of features and security options and with changes to the Data Protection Act coming in May 2018, in the form of GDPR now is a good time to look at alternative solutions.

  • Will my server continue to work?

In short, the answer is yes. BUT as a hardware appliance, should you experience a hardware fault, you may be left without a file transfer server, whilst you source a replacement. Investigating an alternative now could be vital for a continued service to your customers.

  • Can I speak to a technician who understands StingRay?

Yes – although StingRay is no longer being developed or supported, Pro2col are still here and our engineers have a full understanding of StingRay and are available to offer advice when required. Get in touch here.

MFT software enhances security, provides visibility, supports compliance (GDPR, ISO) and can increase the efficiency of business processes. There are many different reasons why an IT team or department within a business may want to install an MFT solution.

Business departments are typically looking to:

  • Securely share files, as email isn’t sufficient
  • Collaborate on project files with geographically distributed teams
  • Enable timely file transfer so that IT isn’t a business bottleneck
  • Have better visibility of files transferred, accessed and downloaded
  • Automate repetitive processes to free up resources
  • Transfer files faster – replacing shipping of media such as media USB devices, DVD’s & HDD’s
  • Send large data sets, quickly to trading partners across the world

IT often looks to Managed File Transfer to:

  • Replace insecure/legacy/open source FTP servers
  • Remove the single point of failure of homegrown bespoke file transfer solutions
  • Enable business users to send files securely without involvement of IT
  • Integrate with Enterprise systems, e.g. SharePoint or cloud services, e.g. Dropbox, Amazon, Azure
  • Automate the movement and integration of data between disparate systems and endpoints
  • Achieve compliance with company, industry or regulatory standards such as Data Protection, GDPR, PCI, SOX and HIPAA
  • Control the use of consumer-grade cloud-based services
Managed File Transfer


Managed File Transfer

Open Source FTP Servers:

For those wanting to build out their own system, a few open source projects exist. However, they require a considerable amount of work to ensure they are fit for purpose. Whilst commercial support might be available, they don’t have the financial backing to allow for a comprehensive list of features, instead of enabling IT professionals with development expertise to address tactical problems. Growing these systems is painful and the development costs can be significant.

Microsoft IIS FTP:

IIS FTP is deployed extensively for tactical solutions. Its lack of functionality and protocol support rule it out as a serious option for organisations that need to meet certain security mandates and regulatory compliance. We explore the limitations of IIS for FTP in the blog article, ‘Pitfalls of using IIS for FTP’.

FTP Servers:

The bottom line with FTP servers is that you get what you pay for. FTP server software is available online, ranging in price from $50-$1500.   The level of functionality and critically support vary widely. Where requirements are minimal, then they prove to be a cost-effective option for transferring files. Our blog article examines this in more depth looking at the top three drivers for choosing MFT over FTP. Find out more in our blog post, ‘MFT or FTP?


Middleware systems bring the ability for the various applications both inside and outside the network to talk to each other. They generally have a hub-and-spoke arrangement with data transformation being performed as messages pass through centralized message queues. Middleware systems come with connectors to most system types, which allow them to exchange data freely. However, they are rarely for use by end users and don’t tend to handle large messages well when compared to dedicated Managed File Transfer Systems. Whilst it is fair to say that not all Managed File Transfer systems offer data transformation possibilities, the development costs associated with Middleware combined with their limitations outside of workflows means that selecting middleware for file transfer purposes is widely considered a poor choice.The price of middleware eclipses most Managed File Transfer solutions and is a key driver when deciding between the two options. MFT can deliver 80% of middleware functionality for 20% of the price. Our blog article below gives further insight into the differences between the two technologies. Find out more in our blog post, ‘MFT Versus Middleware’.
