PGP Desktop products (Pro/Home) provide a neat set of features for all your email encryption, file and disk encryption needs in one nice package but for a price. However there are open source alternatives that offer similar features, which are more than enough for home and small business users. PGP Desktop offers great set of features for Enterprise customers with server based management and recovery features, but these features are rarely needed in a small business or home environment. The tools presented here have existed for a while but even then the security and small business community seems to gravitate more towards PGP Desktop, this entry is merely a reflection to say that all the features of PGP Desktop are available for free and in open source if your willing to work with 3 well developed applications.
