I recently was "directed" to FlipsCloud, a company selling security solutions (as far as I can tell).
In particular I've investigated their page and found a page on their "encryption features".
This page claims a few things (some of which deserve their own questions).
As for this question, I'm asking:
How can one construct the "security strengths" given on the page?
For everyone not wanting to visit this page, he's the chart in question in text form:
Security Strength of Encryption Technologies
2x AES-256 bit(CBC) 99.99%
1x AES-256 bit(CBC) 50%
AES-128 bit 40%
RC4-128 bit 30%
RC4-40 bit 10%
