What is AS2?
AS2 (Applicability Statement 2) is an efficient and secure HTTP-based protocol used to transmit messages in EDI systems. Many large-scale organizations utilize AS2 to share information across EDI systems across many different industries automatically.
AS2 messages are encapsulated in multiple packaging layers. These layers help ensure the message is sent securely and not tampered with in transit. These layers are:
- HTTP/Encryption Header
- Encrypted HTTP Body
- Signature Package
- Message Payload
- Digital Signature
Here are our top picks for the best AS2 software:

What is AS2 used for?
The AS2 protocol is primarily used for business applications to conduct transactions across multiple trading partners securely. In addition, these standard protocols help businesses share information at scale in EDI systems by keeping data uniform across every part of their journey.
AS2 is used widely in retail, insurance, and government to process large amounts of data effectively.
What are the advantages of AS2?
AS2 is highly secure and uses asymmetric key cryptography to keep communication confidential. Although a common misconception is that AS2 only uses HTTP to send data, this is not entirely true. Information is always encrypted before sending in AS2 messaging and given a digital signature for authentication.
When compared to systems before the internet, AS2 is considerably more cost-effective than sending physical documents. In the past, secure transactions would have to be sent via physical mail. This not only took significantly longer but could allow for the message to be lost in transit. Instead, AS2 uses fundamental internet protocols to send messages and share data securely send.
Sharing data via AS2 allows for companies to have updated information on each side in near real-time. This is incredibly important, securely send for specific industries. For example, the AS2 protocol can securely send real-time inventory updates from the warehouse to the retail stores allowing them to plan their next shipment based on the most accurate information.
Is AS2 the only option?
Depending on your use case, the AS2 protocol is not the only option for sending files securely at scale. For example, SFTP, SFTP, and MFT are all viable protocols that EDI systems and other applications can use to move information securely.
Many platforms support multiple protocols, allowing companies greater flexibility in how they build their EDI platform. With that said, let’s take a look at some software that achieves secure file transfer through AS2 and similar protocols.

1. JSCAPE AS2 Server (FREE TRIAL)
JSCAPE MFT is a platform that manages secure communications by forming an endpoint for authentication and encryption processes. Among its capabilities, it provides an AS2 Server. This tool can provide automated EDI message transfers, which can be queued and released on a timer. The platform also receives incoming EDI messages protected by AS2. It can then repackage those messages and forward them, possibly applying a different form of security for internal traffic.
Key Features:
- Multiple Deployment Options: On-premises, hybrid environment, cloud, and SaaS/MFTaaS
- A Secure Transmission Hub: Repackages and resends messages
- AS2 Capabilities: Also FTPS, SFTP, HTTPS, and OFTP2
- Drummond Certified: Security enforcement

Why do we recommend it?
JSCAPE AS2 Server provides a secure channel for AS2 financial data transfers and it can also securely move files with SFTP, FTPS, and HTTPS among other encrypted transfer protocols. The platform also provides options for managed file transfers (MFTs), which involves mixing application triggering with transfers through scripts.
JSCAPE’s position on the boundary of the network gives it the ability to control and scrutinize all traffic, making it an effective data scanner. The gateway, provides all external encryption services for a network’s communications. All transmitted data passes through the gateway in either direction, presenting an opportunity for virus scanning and content examination for incoming messages and data loss prevention scans for outgoing messages.
The AS2 part of the MFT gateway forges secure connections with counterparts and then applies transmission security for EDI transmissions. Simultaneously, the server will manage other types of traffic. JSCAPE can manage connection security with SFTP, FTPS, and HTTPS.
The JSCAPE service also provides a plug-in for Outlook clients. This provides an opportunity to scan both incoming and outgoing emails. That enables security processes to be implemented to identify phishing and impersonation attempts and block or control the movement of sensitive data.
Who is it recommended for?
The JSCAPE system is an MFT service and it isn’t limited to JS2 transfers. This makes the platform suitable for any company. However, an MFT system has far greater capabilities than a typical file transfer service because pre- and post-transfer processes can be integrated into the data movement task.
Pros:
- Malware Scanning: Provides opportunities for sanitizing incoming transmissions
- Operates as a Proxy Server: Manages all connection security for a network’s external connections
- Can Scan Outgoing Messages: Implements data loss prevention
- Data Protection Standards Compliance: PCI DSS, HIPAA, and SOX
- Available for all the Major Operating Systems: Windows, Linux, Solaris, and macOS

- Execution Modes: GUI and command line
- Drag and Drop Interface: Useful for manual transfer execution
Why do we recommend it?
WinSCP is the most widely-use free file transfer system in the world. Unfortunately, it doesn’t have an AS2 integration. You would have to run an SFTP connection through a converter account with another system, such as AS2Gateway, which is a paid system and removes the advantage of using the free WinSCP.
Of all the free file transfer solutions available, WinSCP has one of the most vital communities. This is important because bugs are patched quickly, and new features are regularly added to the user forums. -In addition, community-built plugins add additional functionality when needed without bogging down the initial installation of the product.
WinSCP offers support for multiple protocols. In addition, community-built, including FTP, FTPS, SCP, SFTP, WebDAV, or S3, giving it a massive amount of flexibility over smaller tools. The interface is easy to use and even offers a command-line interface (CLI) tool for administrators, making it less resource-intensive.
The real power behind WinSCP comes from its scripting capabilities, allowing administrators to create in-depth workflows, automation, and schedule without being restricted. In comparison, this is a powerful feature, and it’s only reserved for WinSCPs more technical users. In addition, while the platform is free and open-source, it has extensive knowledgebase articles and forum posts to help guide new users.
Who is it recommended for?
WinSCP is a useful tool for any business to have. In fact, it is possible that you already have it. The system can integrate scripts, which means that it could be used to create automated MFT-style processing. However, as has already been mentioned, it doesn’t have AS2 capabilities.
Pros:

MFT Gateway is a solid option for those looking for secure file transfer as a service. In addition, the monthly subscription model helps lower the barrier to entry, making it a viable option for more budget-conscious businesses.
Who is it recommended for?
Like Fortra’s system, this tool would be very appealing to financial organizations. However, the seemingly low subscription rate for the package is deceptive. The throughput allowance for each plan is very low and just a baseline. Transaction counts above the provided allowance are charged for at an extra rate per transaction.
Pros:
- Off-the-Shelf Integrations: Connects to many widely known platforms
- Choice of Encryption System: Also a choice of sign digest algorithm
- Serverless System: Add it as a service to your own AWS account
Cons:
