Warning: TrueCrypt is not secure. See this post for details and information on migrating to Bitlocker or FileVault.
According to the Star Tribune, detailed personal information for 257 people, including social security numbers, was on a laptop stolen about three weeks ago. The laptop belonged to a vendor, Promissor Corp., who apparently does not observe the basic security precaution of encrypting information on portable computers and drives. I bet that would have been cheaper than paying for credit monitoring for 257 people, especially since excellent encryption software like TrueCrypt is free.
