Envault: Removable media security moves beyond passwords

The ubiquitous flash drive represents one of the most common corporate data security risks. Until now, practically the only means to protect sensitive data held on removable mass media has been a password determined by the user.

“Studies indicate that the most common types of passwords remain simple series of numbers or personal details, both of which are relatively easy for hackers to crack,” says Envault Corporation’s Chairman of the Board Ossi Pohjola.

Envault Corporation’s envaulting technology  consigns passwords to the history books. The  process for text documents, for example, is  to diffuse the data with standard encryption and then to remove ca. one percent of the bits from the diffused data. The fragment file with the one percent of data is sent to the corporate server while the remaining 99 percent is written to the removable storage. Without the missing one percent, the data is unreadable. “This one percent serves as a key and it remains under the absolute control of the enterprise.”


One of a kind world-wide

The envaulting technology is an innovation of VTT Technical Research Centre of Finland. Established in 2007 to commercialise this innovation, Envault Corporation serves a customer base consisting of major enterprises and organisations such as the Finnish Defence Forces.

 According to Ossi Pohjola, the innovation by VTT is without parallel anywhere in the world. “The data protection is impossible to crack, besides which the process is also highly user-friendly.”

This data protection solution requires no action on the part of the user, as the computer automatically recognises any removable media connected to it. The software also monitors and logs all file activity with removable media for a full audit trail.

When corporate data is required beyond the reach of the corporate server, the removable device can be equipped with a ‘time lock’ which makes its contents available for e.g. a 24-hour period. The data protection solution works with all removable mass media in both PC and Mac environments.

Customer-driven product development

Envault Corporation has several patents pending for applications of the innovation. Chairman Pohjola says the company is also developing solutions tailored to its clients’ wishes, addressing issues such as partial workstation hard drive protection and online services.

In principle, the software could be used by individual consumers as well. “Consumer distribution is resource-intensive, however. A small start-up needs to allocate its resources where they do the most good,” Pohjola observes.

Headquartered close to Helsinki International Airport, Envault Corporation is currently setting up a network of international distributors. Sales offices have already been established in the United States, Germany and Dubai.

Envault Corporation is a partner in Tekes’ Safety and Security programme. Chairman Pohjola says the company has received invaluable support from Tekes’ funding programme for young innovative growth companies. “The programme makes it possible for a small start-up to go international. Without it, we might have all of one international distributor at present.”
