SSL file transfer is a term sometimes used in referring to a secure file transfer protocol known as FTPS or FTP-SSL. FTP is a network protocol used for transferring files, while SSL is a protocol for encrypting information sent over a network. This post is meant to help users understand what FTPS is and what it is capable of doing, particularly in terms of enhancing the security of your file transfers.

An MDN is an electronic return receipt which a trading partner can optionally request during an AS2 interchange. The use of MDNs help enforce data integrity and non-repudiation in AS2. In this post, we'll talk more about the value of issuing an AS2 MDN, what options you have when using it, and an overview of the usual configurable MDN settings in a managed file transfer server.

There may be instances when you'd want external users to access HTTP servers located behind your corporate firewall. A secure way of doing that is by allowing access to those servers through a HTTP reverse proxy. In this short tutorial, we'll show you how this can be achieved using JSCAPE MFT Gateway

Choosing Between SSL Implicit, Explicit, and Forced Explicit Modes

There will be times when you'll want to transfer files over a secure connection. One option is to use FTPS (FTP over SSL) which provides data-in-motion encryption through SSL (Secure Sockets Layer). When you setup an FTPS service in JSCAPE MFT Server, you'll notice that you actually have 3 modes to choose from explicit SSL, forced explicit SSL and implicit SSL.

In this post, I'm going to take you through the steps of setting up JSCAPE MFT Gateway to establish load balancing across two FTP servers. Load balanced servers can help you achieve high availability for mission critical file transfer services. We're going to start by creating a new FTP cluster consisting of two FTP servers. Once that FTP cluster is ready, we'll then make it accessible to clients by creating an FTP reverse proxy service that will forward client requests to that cluster.

How to Setup a FTP Reverse Proxy

JSCAPE MFT Gateway Reverse Proxy


I'm now going to show you how to enable a reverse proxy service on JSCAPE MFT Gateway. By setting up a DMZ-based JSCAPE MFT Gateway to reverse proxy for one or more file transfer servers in your internal network, you can employ DMZ streaming. This will allow you to provide trading partners and other external users access to your sensitive data without placing the data on any DMZ-based server.  

Three Reasons a Reverse Proxy is Worth the Investment

reverse proxy serviceFor any business, its data is a critical part of its functioning. This data is constantly being accessed and shared among employees, clients and staff, making secure file transfer services essential.
With the amount of information flooding in and out of company servers, there is always a higher chance of data loss during the transfer, and more importantly, a system could be hacked, and its security breached.
For this reason, many companies invest in reverse proxy services.
What is reverse proxy?
Reverse proxy is a type of server that retrieves information from one or several servers, and transfers this to the client requesting the information. This allows a company's reverse proxy to identify the source, or client, and authenticates the transmission of information without the client being aware of its origin.
Here are some of the benefits of using a reverse proxy service.
  • Security. When an internet user or client sends a request for a file transfer, the request is first sent through a firewall, and then enters the reverse proxy for authentication before retrieving the data from the internal file transfer servers. This blocks clients from determining where the information is coming from, making it harder for hackers to get through to the main servers and steal crucial company data. In fact, accidental deletion, viruses and other disasters have affected a whopping 70% of businesspeople, making reverse proxies even more critical for protective reasons.
  • File Compression. One of the main advantages of using a reverse proxy is its ability to truncate large file requests as they come in from clients. In other words, the information that enters the system is translated into smaller bits than in which it was originally requested. This decreases the loading time, because the bandwidth is reduced significantly. Consequently, when the information reaches the back-end servers, they are able to respond to the request quickly, and the reverse proxy re-compresses the information, sending back out to the client in a more timely fashion.
  • Balanced Load. At any given time, there could be a number of requests streaming in from clients who need access to data from internal servers. What a reverse proxy does is take the requests and distribute them to the appropriate servers. This also helps balance the load of requests shuffled through, so that no server is overloaded. Excessive incoming requests to a dedicated server could cause severely slow loading times. This is one of the most widely-known uses of a reverse proxy.
