Best AS2 Tools

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.

  • AS2 capabilities
  • Drummond Certified
  • Data Loss Prevention

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.


  • Provides opportunities for sanitizing incoming transmissions
  • Manages all connection security for a network’s external connections
  • Implements data loss prevention
  • Data protection standards compliance
  • Available for all the major operating systems
