AS2 What is AS2?Īpplicability Standard 2 (AS2) best for business-to-business EDI (Electronic Data Interchange) transactions – perfect for industries like retail and manufacturing. Also, there’s no way to schedule or automate transfers with HTTPS, which is possible with other methods like SFTP. In many businesses, complex files are transferred every day, so this is a major drawback. This method is best for the transfer of small, simple files. HTTPS can make it difficult to transfer large files. Plus, all traffic to a HTTPS website is encrypted, which maintains user privacy. Users only need the right URL to access a file. Also, there’s no need for any kind of protocol installation, which would be the case with FTP or SFTP. In fact, most people have already used this method in some form or another, so there’s very little education would be needed to ensure your team is using HTTPS effectively. HTTPS makes it highly simple to download files straight from an internet browser. Like FTPS, it’s imperative that your system allows HTTPS but not HTTP. HTTPS (Hypertext Transfer Protocol Secure) adds the layer of SSL/TLS security HTTP needed by encrypting the connection. While this method is simple, it offers nothing in terms of security. HTTP allows you to share data via a web browser. Plus, not all servers enforce the use of SSL on port 21, so your organization may be open to employees accidentally using unencrypted FTP. This level of internet exposure can make it incompatible with company firewalls. Whereas SFTP transfers only need one port open, FTPS requires multiple ports to facilitate data transfers, in the same way that FTP transfers do. Also, SSL is a popular form of authentication, and many methods of internet communication already have SSL built in. You don’t have to worry about your data transfers being compromised, since you’re using encrypted connections to share data. The biggest benefit of using FTPS is, like SFTP, the added security. ![]() FTPS enables you to encrypt both the command and data channels, and authenticate transfers with usernames and passwords, certificates, or both together. SSL, or “secure sockets layer”, FTP transfers use the same control channel (port 21) to facilitate data sharing, which means your system needs to be able to accommodate FTPS, but prevent FTP transfers. FTPS What is FTPS?įTPS (File Transfer Protocol SSL) transfers files the same way as FTP, but with an encrypted connection to protect data. Everyone knows how usernames and passwords are used to log into accounts, but not everyone knows how SSH keys (another form of authentication) work. Users need to download and install SFTP Client software on their computer and IT departments may need to get involved in allowing these tools to be installed.Īlso, if you start using SFTP Clients in your organization, there may be a learning curve for your employees. But that doesn’t mean it’s totally without its drawbacks. Drawbacks of Using SFTPįundamentally, using SFTP is pretty simple. Finally, you can glean more metadata from transferred files, like send date and time, and file size. Another benefit of SFTP is that only one server connection is used to share data, so no other ports need to be open, diminishing the burden on configuring your firewall. The encrypted transfer means that not only are your transferred files encrypted, but your username and passwords are encrypted in transit, too. The biggest benefit of using SFTP is its data security. Once the connection is established, all data is securely transferred via the encrypted channel. Client computers encrypt the channel only after validating the server’s SSH host key. SSH (secure shell) encryption allow two computers to establish a secure channel before a transfer occurs. Using SFTP closes this security gap by adding a layer of security – SSH encryption. One of FTP’s biggest vulnerabilities is that all information, including potentially sensitive information, is shared over plain text, including your username and password. SFTP, or FTP over SSH, is an FTP alternative that deviates from traditional FTP transfers in a key way: the application of SSH keys to the process. Let’s take a look at a few different options and determine how these alternatives address data security. Here at FTP Today, we have developed secure file sharing solutions for our clients for more than 20 years. ![]() With data security continuing to be a major concern for companies, it’s essential to explore alternatives to FTP. As technology advances (and hackers’ skills advance in parallel), you need the best file transfer option to keep data protected. However, looking at the complexity of data security compliance standards and the capabilities of data hackers, a stronger and more secure solution can be required. FTP (File Transfer Protocol) has been a leading option in file transfers for a long time.
