While most security packages employ 128-bit encryption, Data Guardian goes a lot further with a staggering 448-bit level of protection.
The Blowfish protection system is enough to stop all but the most determined hackers. The program basically allows you to create multiple databases based on different themes e.g. an address book, customer database, journal, password manager, or even notepad. With 448-bit encryption employed on each of these however, you can be sure that they'll be pretty safe even if they're not stored locally.
The program prides itself on customizability - i.e. you can create just about any kind of database you require with any category or color coding of your choice. The program also offers to remember and auto-fill passwords. Although Firefox and IE also do this now, you're probably much safer using Data Guardian because of the encryption protection that surrounds your data.
It also offers a few other useful shortcuts such as one click calling based on auto recognition of phone numbers, instant access to your e-mail client via auto recognition of e-mail addresses and generation of secure passwords.
A well designed a super secure database/productivity enhancement application, Data Guardian gives you more than one less thing to worry about.
