Introduction

Fortinet FortiClient is an enterprise-grade solution managed via a central console. It features web filtering capabilities that operate similarly to parental controls, restricting access to specific website categories like adult content. We evaluated these filtering features using the identical testing methodology applied to consumer parental control software.

Parental Control Certification

AV-Comparatives provides certification for parental control software. In order to be certified, a product must block at least 95% of pornographic websites, have zero false alarms on child-friendly websites, and have no severe unresolved bugs (or design flaws) discovered during the review. A certification is valid for one year and vendors can apply for certification once a year. Only products which were submitted for the Parental Control Test, and which passed the test, are published. Four vendors submitted their products for certification in 2026, of which only two reached the requirements.

Parental Control Test

We tested the effectiveness of the parental control software against 1,000 websites with inappropriate content for children, such as sites displaying pornographic images and text. We chose the appropriate settings for blocking pornography. We additionally tested 200 obviously child-friendly websites, such as lego.com, to check for false positives

General advice to parents on choosing and installing parental control software

When choosing and installing parental control software, remember that no program can replace the
value of talking to your children about adult or disturbing topics they may encounter. Even with
parental control software installed, children might access inappropriate content through mobile
devices borrowed from friends or by using technical workarounds like proxy servers. Parental control
software is most effective in preventing accidental exposure to inappropriate content for younger
children.

Selecting the Right Software

Before purchasing parental control software, ensure it meets your specific needs. Standard features
include web content filtering that blocks categories of websites such as pornography or weapons.
Other features to consider are setting time limits on device usage or Internet access. You may want
to restrict usage to certain hours or empower your child to manage their usage themselves. For a
shared family computer, check that the program allows unrestricted use for adults. To be sure the
program meets your requirements, try a trial version first. Don’t hesitate to seek expert assistance if
needed. We recommend using parental control software which is regularly tested and certified by
independent third-party labs. This ensures that the software meets high standards for effectiveness
and security without causing false alarms.

Installing the Software

When installing parental control software on a Windows or macOS computer, it’s crucial to prevent
children from easily disabling or uninstalling the software. You can achieve this in two ways: use
parental control software with password protection or ensure your child’s account does not have
administrator rights. In either case, use a password your child cannot guess. To properly configure
the software for your child, log in to their account during installation and use your administrator
credentials to authorize the installation. After installation, test the software with various browsers
and websites to ensure it works as expected. Verify that it prevents computer usage outside of
permitted hours and cannot be uninstalled without a password. If you encounter any issues, contact
the vendor’s support service. Finally, remember not to save the password when configuring the
software via a web browser.
