Secure Cloud Email for Hosted Exchange

Cloud-based security vendors have been brimming with email solutions for corporations lately. And as security threats diversify with the uptake of smartphone and tablet browsing, you can’t blame companies for wanting to secure their applications in the best possible ways, especially with corporate email accounts being frequently bombarded with spy apps and malware threats.


Whether the service by Vaultive is all it is cracked up to be or not, the basic concept is spot on. Vaultive is a cloud date encryption provider which allows organizations to take full control of the cloud computing which takes place on their premises, employees and all. It allows company control while maintaining data security, control and the compliance advantages of the company’s cloud computing, particularly email. Recently, the company has announced it will provide Hosted Exchange. This is their latest cloud data encryption solution that allows users to encrypt both data-at-rest as well as data-in-use within the Microsoft Exchange Environment. The unique part is the complete control of encryption keys given to a corporation’s IT department.

More importantly, since Vaultive is the only cloud data encryption solution designed specifically for Hosted Exchange on the market right now, it gets more exposure — more market, too, since it has launched itself globally and can be used with any and every Hosted Exchange service. These exchanges include Microsoft Office 365 and SaaS applications. The encryption technology is patented and allows data-in-use and data-at-rest both to be encrypted via advanced AES technology. Hence there is no hindrance due to data transits. No wonder it has already managed to grab the attention of leading capital firms such as New Science Partners, Harmony Partners, and Stillwater LLC amongst others.

Small Businesses Can Join the Club Too

The thing is, corporations feel that a Hosted Exchange environment benefits them more than any other IT solution. This applies twice as much to small businesses. As far as they are concerned, nothing is more vital to their survival than email. But managing that can be costly and time-consuming. At the same time, getting Hosted Exchange would mean a whole refocusing of IT resources. So for small businesses (since I see no way in this day and age they can survive without getting onto the personal exchange bandwagon), purchasing an exchange service from a larger business or company for a monthly fee is a good idea. This gets them email security as well as saving them the money needed to set up a hosted exchange on their own premises with their own resources.

Businesses are beginning to question data encryption methods too, and are seeking to make sure encryption tools are within their own grasp at some level. This breaks the power hierarchy that sees security providers on the top rung, when it comes to IT department collaborations. And this trend of awareness has to continue. The future market share and needs make it obvious that more options for Hosted Exchange security will be required. And since Hosted Exchange is catching on regardless of company size, varying security needs will have to be addressed too. Businesses might as well start auctioning themselves at this point.

Blind and Double Blind Environments

The significance of using this security solution is more long term than many may consider. For one, moving email to the cloud gives companies a more secure and isolated data environment. Email used by employees via devices is always open to cellphone monitoring and malicious data deletion apps. Similarly, email through PC is susceptible to monitoring software and similar removal/deletion threats.

Threats abound everywhere and some cloud vendors can be shady. And so the fear of losing data remains. But this is where blind and double blind secured hosted exchange differs; they do not directly play a role in data encryption or handling. They allow users to retain complete control over their data while keeping themselves — the security company as well as exchange providers (in case of small businesses) — safely unaware. Allowing a company to deal with their information on their own terms rather than relying on third-party management gives companies a sense of empowerment in the cloud, something ordinary email practices and other cloud-based email vendors do not offer.

In the long run, there is no external management to deal with and a corporation can continue its affairs without having to wander to and fro between security vendors. It seems the future is headed in this direction anyway, so why not work towards securing this particular cloud practice?
