Evertrust Eases Expunging: Page 2 of 3

AEstor addresses this problem by putting digital fingerprints on each document, allowing administrators to track how long a file has been in storage, and when it needs to be deleted. Once the retention period is up, administrators with proper clearance can physically remove accessible online data or scrub the encryption key for documents that are not accessible for physical destruction, thus rendering them illegible.

Since AEstor uses AES encryption standard with 256-bit keys, Gosnell insists there’s no way of breaking it. “This ensures effective elimination,” he says. “We leave the information there… but the asset can no longer be reconstituted.”

At least one analyst says Evertrust.net isn't doing anything new. “I don’t think it’s anything earth shattering. A lot of archiving products offer the deletion at the end of the retention period,” says Sara Radicati, analyst at The Radicati Group Inc. consultancy. Big industry players like KVS Inc. and Legato Systems Inc. (Nasdaq: LGTO) already have similar products (see Legato Mines Iron Mountain and EMC, Iron Mountain, KVS Archive Email). “But it’s great to see another company enter this space. We think it’s a very, very important space, and it’s great to see more choice,” Radicati says.

The Radicati Group estimates the archiving market is currently growing by 85 percent a year and forecasts growth from $164 million this year to 1.5 billion by 2007.

Evertrust.net hopes to avoid going head-to-head with large market players on direct sales. Instead, Gosnell says, the company is in the process of wooing storage vendors to integrate its software into their existing products, Gosnell says. But the Lafayette, Calif.-based startup has yet to sign up a single OEM partner for AEstor.
