Files.com achieves its best-in-class security by providing customers with a file server platform that is tuned for maximum security out of the box, with no manual configuration necessary. This means that things like strong encryption enforcement, brute force protection, and IP address pinning for web sessions come built-in and enabled by default.
We also realize that every organization has unique security requirements, so we give site administrators full control over these security features, allowing you to fine-tune your site settings to meet your needs.
Administrators can access these settings in the web interface at Settings > Security.
Insecure FTP support
By default, Files.com will reject FTP connections to your site that do not use secure encryption. If you need to support very old devices or clients of the FTP protocol, you can use this setting to allow insecure FTP connections (port 21 without SSL).
You can also allow insecure FTP connections on an individual user basis via the Insecure FTP support user setting.
Note: Allowing insecure connections is dangerous because it will cause passwords and file contents to be transmitted across networks in clear text.
Default: Require SSL on all FTP connections (recommended)
HTTPS, FTPS, and SFTP ciphers
This setting allows compatibility with old browsers and old SFTP/FTP clients by allowing SSLv3, TLSv1.0, SHA1, and other ciphers that are known to be insecure but required by older versions of clients.
Note: Enabling this option is dangerous because an uninformed user of your site might think that they are using secure encryption when they are actually using encryption that is broken. You should treat all connections to your site as if they are fully insecure if you use this option.
Files.com supports the following secure, contemporary SFTP ciphers by default.
The following insecure SFTP ciphers are supported only when allowing connections with insecure ciphers.
Default: Only allow connections with secure, contemporary ciphers (recommended)
Site-wide IP whitelist
The setting found at Settings > Security > IP Whitelist allows you to limit which IP addresses your users are allowed to connect from. List allowed IPs, one per line. You may specify a range in CIDR format, such as
If you have also set up user-specific IP whitelists, users connecting from an IP address matching in either whitelist will be allowed to log in.
User-specific IP whitelist
You can manage IP whitelisting for individual users via the IP whitelist user setting. If you are also using a site-wide IP whitelist, users connecting from an IP address matching in either whitelist will be allowed to log in.
Advanced Security Settings
Brute force protection
This feature is an extra layer of protection for organizations that desire an aggressive level of security, as general brute force protection is already provided by Files.com. It will lock users out after a given number of failed login attempts, further protecting you from brute force password guessing attempts.
Note: Care should be taken if enabling this setting to avoid accidental user lockouts. We recommend having at least one backup administrator user who will be able to unlock another administrator in the event of an accidental lockout.
Default: Use default Files.com protection
Session IP address pinning
This setting helps to secure your site against session hijacking attempts by pinning user sessions to the IP address they originated from.
With this setting enabled, users will be asked to log in again if their IP Address changes. This could occur when they change networks, such as moving their laptop from the office to their home network. Disabling this setting is required at some office networks which rotate public IP addresses.
This setting does not apply to the Desktop app, which uses longer-lived session tokens (see Desktop Session IP Pinning).
Default: Enabled (recommended)
Web interface sessions will automatically expire after a period of inactivity. Use this setting to customize the session idle timeout if needed.
Default: 6 hours
Desktop Session IP Pinning
Similar to the Session IP address pinning setting, enabling this setting will force users of the Files.com Desktop app to log in again if their IP address changes while they are logged in to the Desktop app.
Desktop Session Lifetime
The Desktop app uses session tokens which have a limited lifetime. Use this setting to customize how long those sessions last once a user has logged into the app.
Default: 720 hours (30 days)
