Bitdefender Internet Security Software For Windows builds on technology awarded by AV-TEST Best Windows Protection for three years straight, and Best Performance for system speed. It is exceptionally easy to use. It detects when you are working, playing, or watching movies, and prevents apps from slowing down your system. One-Click Optimizer frees up hard disk space. This software offers network protection by preventing unauthorized access to your private data with a two-way firewall. Additionally, the state-of-the-art antispam technology blocks all unwanted e-mails, and keeps your children safe by helping you monitor their activities with complete yet subtle Parental Control.

This is the main window that looks almost identical to that of the basic suite. Once installed, Internet Security offers a few useful recommendations to its users via the AutoPilot feature. From the Dashboard section, users can effortlessly launch quick scans, open the VPN, activate SafePay banking protection, as well as install Internet Security on other devices.

Users can also add a “quick action” in this menu, meaning that they can pin features that they use the most to the dashboard. Underneath the Dashboard, on the left-side menu, there are three more important pages appropriately named Protection, Privacy, and Utilities.

While they are also visible in the Bitdefender Antivirus Plus product, Internet Security has the advantage of having all Protection and Privacy features available (in the Antivirus Plus product, some of them are greyed out). Since we are on the subject, it’s also worth noting that the features from the utility section still require an upgrade to the Bitdefender Total Security package.

You Are Safe

It should not take more than a couple of minutes to figure out that Bitdefender Internet Security is a very comprehensive security suite, with features that are not found even in some top-tier suites from the competition. Installing it on any Windows computer will provide users with top-notch antivirus, a firewall, spam filter, malicious website blocking, online banking protection, extremely comprehensive parental control, VPN, a password manager, a security file deletion feature, and basic file encryption options.

The Parent Control feature is definitely one of the best features of this suite. It allows users to manage profiles for each child (the app supports an unlimited number of profiles). The features use local clients to enforce the security results on a wide range of OSes such as Windows, macOS, Android, and iOS. Users can also establish how much screen time is right for each individual child, as well as block inappropriate content and make browsing safer.

It is also very well equipped at dealing with ransomware. One of the main novelties for the latest version of Internet security is the Ransomware Remediation feature which acts as a protection layer for all your personal documents. The product also detects and repels most online threats thanks to its network-based adaptive layers of protection.
