    Bitdefender`s unbeatable multi-layered protection keeps your devices safe from all new and existing threats.

    Complete Real-Time Data Protection IMPROVED

    Absolute power in the most efficient Internet security suite available today. Bitdefender Internet Security works against all e-threats, from viruses, worms and Trojans, to ransomware, zero-day exploits, rootkits and spyware. Your data and privacy are safe.>

    Network Threat Prevention

    Bitdefender Internet Security stops attacks before they even begin. The new cyber threat intelligence technologies included can analyze and identify suspicious network-level activities, and block sophisticated exploits, malware and botnet-related URLs, and brute force attacks.

    Advanced Threat Defense

    Bitdefender Internet Security uses a technique called behavioral detection to closely monitor active apps. The moment it detects anything suspicious, it takes instant action to prevent infections.

    Multi-Layer Ransomware Protection

    Bitdefender’s multi-layered approach against ransomware includes a data-protection layer that safeguards your documents, pictures, videos and music against all kinds of ransomware attacks. It works with the Advanced Threat Defense module to protect your most important files from encryption by ransomware.

    Vulnerability Assessment IMPROVED

    Scan for security holes and vulnerabilities with just one click. Bitdefender Internet Security checks your PC for outdated and vulnerable software, missing Windows security patches and potentially unsafe system settings, then indicates the best fix.

    Web Attack Prevention

    Our web-filtering technology ensures that you never land on a harmful website. Find out whether your search results are safe to access before you actually click on a link. Bitdefender Internet Security also blocks all known infected links.


    Online scams are on the rise, but our advanced anti-phishing protection easily keeps you out of danger. Bitdefender Internet Security sniffs and blocks websites that masquerade as trustworthy in order to steal financial data such as passwords or credit card numbers.


    Our advanced filtering system warns you whenever you visit websites that may try to scam you.


    Filters irrelevant messages in your Inbox. It’s available for local email clients (Microsoft Outlook, Thunderbird).

    Rescue Environment

    Some sophisticated malware, like rootkits, need to be removed before Windows starts. When Bitdefender Internet Security detects such threats, it reboots the computer in Rescue Environment for clean-up and restoration.


    Bitdefender’s security software reacts instantly to all e-threats with no compromise to your system’s performance.


    Bitdefender Autopilot is designed to act as a Security Advisor and give you deeper insights into your security posture. Its smart capabilities mean that it can recommend security actions in the context of your system needs and usage patterns.

    Bitdefender Photon™

    This innovative, exclusive technology helps Bitdefender Internet Security adapt to your system’s hardware and software configuration to save computing resources and improve speed and performance.>

    Global Protective Network

    Most heavy scanning takes place in the cloud, so there is virtually zero impact on your local resources. This means your system’s speed and performance remain unaffected. And your files are always completely private: Bitdefender does not scan the actual contents of your files, and never uploads or stores them in the cloud.

    Game, Movie and Work Modes
    Battery Mode

    This useful, intelligent feature saves battery life for laptops and tablets by temporarily tweaking system settings such as display, system cooling, system updates and Bluetooth connectivity.


    Bitdefender Internet Security takes care of your online privacy and personal information.

    Bitdefender VPN IMPROVED

    With Bitdefender VPN, you can stop worrying about privacy on the web. It protects your online presence by encrypting all Internet traffic. Bitdefender Internet Security includes up to 200 MB per day of encrypted traffic for your Windows devices.


    The Anti-tracker extension blocks trackers that collect your data, and it allows you to view and manage this information on each website you visit. It keeps your browsing data private and enhances performance by loading webpages faster.

    Microphone Monitor

    Regain control over your own devices with Microphone Monitor. Use it and you can see what apps have access to your device’s microphone and when.

    Webcam Protection

    Protect your privacy and prevent webcam leaks. Webcam Protection notifies you when apps try to access your webcam, and lets you block unauthorized access.
