Theres no shortage of document task and messaging-oriented collaboration applications, but few offer the security options found in Kasten Chase Applied Researchs Assurency CipherShare.
Available as a hosted application through Online Systems for $75 per user per month (and a $100-per-user setup fee), CipherShare provides robust security through strong encryption and document workflow features.
While most applications in this space are Web-based, the client/server-based approach gives users faster access to data and a better integration of the messaging and chat features. In the hosted version I looked at, I found the system easy to use. A nice feature of the hosted version is the ability for users to pool their 500MB of allotted storage in the shared work space.
I had to manually configure some elements of the client software, but for companies that want to ensure that data remains encrypted at all times, its worth the administrative overhead.
To establish a trusted identity within the system, users have to verify identity via a fingerprint, a text string within the public key. This fingerprint-checking process requires users to verify their identification by phoning a work spaces designated security manager.
I liked the way CipherShare handles document management, especially the ability to download encrypted copies of documents and to work with them remotely.
