Someday, encryption features built into a wide range of IT products -- from operating systems and messaging gateways to hard drives and storage systems -- may work in concert to offer central policy enforcement across different types of network assets and devices.
Until that day arrives, however, companies embracing the tools have become dependent on standalone encryption platforms to give them distributed control and policy enforcement across their IT systems.
Long known as much for their complexity and demand for hands-on care and feeding as they have been valued for their protective qualities, encryption platforms are finally finding their way into a number of large businesses.
This growth in adoption has been driven by the proliferation of data protection regulations and based on the availability of products that address the hardest elements of encryption technology -- policy enforcement and key management, industry watchers contend.
"The performing of the encryption itself is something that generally belongs close to whatever type of data you are trying to encrypt, whether that is e-mail, network traffic, or a database, but companies are buying into technologies today that allow them to do centralized policy enforcement and key management," said Paul Stamp, analyst with Forrester Research.
"It's great in theory to say that all of this activity needs to happen in the infrastructure components themselves," he said. "But that's not a reality yet in terms of allowing for centralized management, so customers are turning to these platforms in the meantime."
End-users agree that encryption has long been a security process they desired to implement but couldn't stomach based on issues of complexity.
The arrival of more usable encryption technology over the last few years has helped eliminate some of the traditional roadblocks, according to some corporate users.
"From my previous experience with e-mail encryption, I had two major concerns with using the tools: Key management and any dependence on the end-user to make the systems work right," said Michael Gabriel, corporate information security officer for Career Education Corporation (CEC) a higher-education provider that operates more than 75 colleges, schools, and universities.
"I haven't ever seen an encryption project where management wasn't a major sticking point, that has been the history of the technology, but it seems that the vendors are finally getting it right," Gabriel said. "Compared to mapping the business process, putting the technology in place was a breeze. The only real sticking point was getting the data flow."
CEC is using encryption tools made by PGP in cooperation with its data leakage prevention and e-mail filtering systems to protect sensitive information being passed among its employees.
Gabriel said that PGP's embedded key management capabilities may be the most valuable aspect of the system -- a feature that simply didn't exist in the past.
Other PGP users echoed those sentiments, saying that encryption tools have advanced significantly over the past several years in terms of eliminating the management headaches that have made it challenging to deploy the systems on a wider basis.
