When will you support SSL landing pages?
The GSA has stated "If PII needs to be transmitted over the Internet, it must be sent using encryption methods defined in the GSA Information Technology (IT) Security Policy (GSA CIO P 2100.1E, Ch. 4, para. 22). www.gsa.gov/portal/content/104276
We do work with government entities and large organizations who have the same PII data transmission policy and as a result we must comply. I have been the largest proponent of using unbounce.com now across multiple companies, but until this feature is available, we must stop using unbounce.com for our internal lead gen efforts.
I also highly recommend that anyone using unbounce.com for your corporate lead gen campaigns consider your security policy and the local laws currently being enacted around secure transmission of PII. If you are collecting PII over http only, you should reconsider.
