Nothing can replace your supervision of your children while they're on the Internet, but there are several excellent options to make your job easier.
Verizon Online has included Parental Controls in the Verizon Internet Security Suite. For an additional monthly fee, you can use the Parental Controls module to restrict your child from looking at certain Web sites, control when your child can access the Internet, and prevent certain software programs like instant messaging from connecting to the Internet.
You can also enter "parental controls" in any search engine to find a wide range of products that are designed to keep your children safe on the Internet.
