Secure Delete for Mac

From Allume Systems:

Secure Delete? is like a paper shredder for your computer files. If you have confidential paper documents you need to destroy, a paper shredder is the best tool. But, today's paperless office needs a tool that safely and effectively handles computer files as well.

Paper documents you crumple up and throw in the wastebasket can be easily picked out and read by prying eyes. The same is true with digital files. Even after you drag files to the trash and empty it, those files can be recovered and read by people who should not have access to them.

With Secure Delete you can permanently remove files with confidence and ease. Just drag and drop the files of your choice onto the Secure Delete icon, and they are gone for good.
