Secure Electronic Communication

In today’s business world, fast and reliable electronic communication is key to success. Messages and files need to be exchanged with contacts around the globe at the speed of light. 
For years, email was the primary solution to achieve fast and reliable communication, but our needs now transcend the capabilities of the established email we've come to use daily and rely so heavily on.

Protect your data

Whether it's sent privately or for business, the information we exchange is often sensitive and in danger of being attacked by criminals, competitors, advertisors, and even governments. We need usable security mechanisms that enable us to keep our information safe. And we need to be able to control who can access it and who cannot.


The age of large file transfers

With the increasing capabilities of electronic devices, the content we exchange is growing ever larger. More and more, we produce files of greater size: images, videos, CAD files, software, database files and so on. Email has not been able to keep up with this trend, especially since the exchange of these larger files is limited. Under pressure, we find ourselves searching for more complex and less secure alternative ways to share this data, usually bypassing established compliance measures in your email workflow. When we do this, we sacrifice control and usually lack the ability to see, immediately and clearly, if and when a file or a message has been delivered and who had access to it.

Take what's already there...

Wouldn’t it be great, if our primary communication tool, our email system – the one we work with every day, that we’ve come to know so well, that works across borders, and is available to us all - could just do all of this? We think it can!


...and make it better

Cryptshare makes email better. It adds security, policy control, audit trail and unlimited file size to your existing email infrastructure and keeps it as simple as it was before. Exchange information with anyone who has an email address: quickly, securely, audited, and without size limits.

The benefits of Cryptshare:

Immediately Improve Security

Too often your projects require you to securely share ideas and files with teammates without having the time and resources to do it effectively. Enter Cryptshare: the most cost-effective and easy-to-use solution to the problem. A typical installation takes less than half a day, and its deployment options make it easy to re-use existing servers, virtual machines, or simply add an appliance to the rack. Customizing the default policies and adding your logo to the front-end to the front-end display takes only a few minutes. Start a trial today, and simply purchase license key to continue.

Build on what you have

Cryptshare solves the well-known problems of e-mail, making it better. But it does not replace this powerful and highly valued tool. You will have invested heavily in the e-mail solution you use the supporting infrastructure, archiving and storage. With Cryptshare you can solve the obvious problems experienced by users of large files and security thereby improving data governance by eliminating ad hoc use of uncontrolled channel. However you also make it possible to massively reduce the amount of data retained inside your e-mail system by the removal of attachments significantly reducing your costs.

Reducing resource demands on your e-mail server

Even a quick examination of the stored content of an email user will show that a very large part of the typical mail-box storage is filled with file attachments. Often these are confidential, there are many duplicates, and they may have been sitting there for some time. By removing large files - perhaps even all files - we can massively reduce the storage demands of each user saving considerable space and cost.

Use from any device

Organizations increasingly face staff demands for access to files and data from many kinds of devices - from smartphones and tablets to laptops and home computers. While a BYOD culture might be appealing and convenient, it creates many security problems. With Cryptshare, any device with a browser and access to email can be used to send or retrieve files and messages. While the use of those files may be limited by the device (for example read only on tablets) being able to give secure and controlled access allows you to take a step in the right direction towards your team's needs.

No more costly file size issues

You face vast quantities of data in your work, much of it contained in large files and it is these files that you want to share to bring your work to life. But email was never designed to deal with them and policies exist to block files or attachments above certain limits typically 20Mb. With Cryptshare this limit is removed! Absolute file size no longer matters and storage and archiving of files no longer needs to be done inside email. Your customers, suppliers and partners are able to send you larger documents with total security, speed, and auditabiliy.

Enhanced Control

Good governance demands that there be a record of the things you send to or share with others, and an audit trail or other policy tool that management can leverage to track how information is used. With Cryptshare, every transfer is accompanied by notifications to the sender and recipient at each stage in the process, which allows you to set policies, maintain a detailed log file, and ensure compliance.

Simple and intuitive to use

The most effective solutions are intuitive and easy to use, driving high user-adoption, and making sure you see value quickly. Cryptshare requires no training training; any user familiar with email should be able to begin right away. The user interface and help functions can be customized to ensure your organization’s policies are adhered to, and even the more sophisticated functions - like user-defined policies - are simple to use. Another key advantage is that Cryptshare can be used directly from a browser, without the need to install a client.


The Cryptshare Short Story

In the past, we used the postal service to send letters and packages to family, business partners, customers, and suppliers, allowing us to extend our reach beyond the local community to new markets. But since sending letters and packages could be slow and expensive, many times we just sent a postcard instead. The problem is, though cheap and fast, the postcard was not confidential. It could be ready by anyone who handled it, and its contents were restricted to the small size of the card.

However much we enjoy its convenience at home and in our professional lives, email has essentially the same problems as a postcard sent through the conventional mail: a lack of security and no way to encompass larger content. In any organization, there are many documents that need to be shared securely, and it’s often the case that what we send via email is sensitive and ought to be kept private.

In many organizations, users have a hard time reconciling their need to share large, sensitive files with the corporate email policies that prevent them from doing so. Restrictive email policies often drive employees to take unnecessary risks in sharing information. Use of disposable media, consumer grade cloud services (DropBox, YouSendIt, etc), complex managed file transfer, and existing email encryption tools are some of of the ways users may try to mitigate these risks, but all of these solutions struggle to find a balance between security, ease of use, and cost.

Cryptshare makes email better by solving these problems in a simple and cost-effective way. It is easy to install and doesn’t require user training. Cryptshare is highly secure, and provides a complete audit trail, keeping track of the senders and recipients of your protected messages and files. It also provides senders with notifications to let them know when their messages and files have been received.

Cryptshare is most often used through a plug-in to your existing email system, though our web interface makes it easy to use Cryptshare anywhere, on any device. We’re making email better by expanding its capabilities, and by building on the undoubted value that makes email our favorite way to communicate. With Cryptshare, email is no longer the problem - it’s the solution.
