Stop risking your sensitive data and send your large files securely right from within your email..



DeliverySlip quickly and seamlessly integrates into existing email environments, such as Outlook, Office 365 or Gmail, as well as with DLP engines, SSO (Single Sign-On) and archiving systems. Fully functional apps for iOS, Android, and other platforms are free and easy to install and use. Plus, because users are authenticated using existing email addresses, they don’t need to create (or remember) an additional profile.


DeliverySlip lets you easily and securely send and receive file attachments of any format and up to 5 GB, both within your organization and beyond. All messages and attachments are protected throughout the exchange and can only be viewed by you and your recipients. DeliverySlip creates a secure community for both internal and external recipients, protecting your communications with bank-grade AES 256-bit encryption.


DeliverySlip’s asynchronous file transfer method fully supports file size limitations set by many organizations. With DeliverySlip, you can send multiple large files at the same time, without having to create a series of multiple, smaller messages due to size restrictions. DeliverySlip breaks down large files into 4 MB chunks while in transit and stores them encrypted on the cloud server to avoid network issues; the DeliverySlip HTTPS API makes it seem like a regular transaction to the network.


Because attachments are shared via the secure cloud, content can be forwarded without having to download a local copy. The same is true for recipients who have been cc’d for “information only” purposes. They can choose whether or not to download content, helping control storage limits on inboxes and hard drives and reducing the load on your network.


With DeliverySlip, you can provide or request authentication on a wide range of files (such as contracts, x-rays, mortgage agreements, etc.) up to 5 GB, without the need for additional complex workflows to accomplish the task. Save time without sacrificing security by streamlining the workflow for approvals for vacation requests, expense reports, PTO requests, and more. Plus, DeliverySlip E-Signature lets you easily and securely request and provide legally binding e-signatures on documents.


Delivery Slip provides live updates the moment a secure message and attachments are received and downloaded. Users can avoid needless follow-up and know with certainty that their content has been received.


DeliverySlip offers numerous options for controlling messages and attachments. Easily control whether messages can be replied to or forwarded; set messages to expire at a later date; or completely recall messages if necessary—even after they’ve been delivered. For especially sensitive information, DeliverySlip’s Confidential and FYEO (“For Your Eyes Only”) provide additional protection to individual messages, requiring authentication credentials or passwords to unlock messages.


When a file is shared with DeliverySlip, it is assigned a unique identifier for tracking, audit, and e-Discovery purposes. This information is displayed in the file’s Delivery Slip, indicating who has accessed, downloaded, shared, or printed the file—complete with timestamps and IP addresses for full non-repudiation. To maintain control over sensitive data, access to files can also be revoked at any time by the owner. DeliverySlip enhances compliance with major privacy and security laws and regulations (including E-SIGN, GLBA, and HIPAA in the US; PIPEDA in Canada; and the Electronic Transactions Act in Australia).
