Protection

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

Full Real-Time Data Protection 

Absolute power in today's most effective internet security suite. Bitdefender Internet Security works against all e-threats, from viruses, worms and Trojans to ransomware, zero-day vulnerabilities, rootkits and spyware. Your data and privacy are safe.

Network Threat Prevention

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

Advanced Threat Defense

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

Multi-Layered Ransomware Protection

Bitdefender's multi-layered approach to ransomware includes a data protection layer that protects your documents, images, videos, and music from all types of ransomware attacks. It works in conjunction with the Advanced Threat Defense module to protect your most important files from being encrypted by ransomware.

Vulnerability Assessment 

Scan for vulnerabilities and exploits 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 Bitdefender Internet Security checks your PC for outdated and vulnerable software, missing Windows security patches, and potentially unsafe system settings, then suggests the best fix.

Preventing Web Attacks

Our web filtering technology ensures you never end up on a malicious website. Find out if your search results are safe to access before you actually click on a link. Bitdefender Internet Security also blocks all known infected links.

Anti-Phishing

Online scams are on the rise, but advanced phishing protection easily keeps you out of harm's way. Bitdefender Internet Security sniffs out seemingly trustworthy websites to steal financial data like passwords or credit card numbers, and blocks them.

Fighting Fraud

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

Anti-spam

Filters irrelevant messages from your Inbox. Available for native email clients (Microsoft Outlook, Thunderbird).

Recovery Environment

Some sophisticated malware, such as rootkits, need to be removed before Windows starts. When Bitdefender Internet Security detects such threats, it reboots the computer into the Recovery Environment for cleaning and restoration.

Performance

Bitdefender's security software instantly responds to all e-threats without compromising your system's performance.

Autopilot

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

Global Protective Network

Most of the heavy scanning takes place in the cloud, so there’s almost zero impact on your local resources, meaning your system’s speed and performance won’t be affected. And your files are always completely private: Bitdefender doesn’t scan the actual content of your files and never uploads or stores them in the cloud.

Game, Movie and Work Modes

Bitdefender Internet Security detects when you're playing games, working, or watching movies, so it knows not to bother you with unnecessary requests. Depending on what you're doing, Bitdefender temporarily stops pop-ups, adjusts visual settings, and pauses unimportant background activities so you can enjoy your device to the fullest.

Arrow Modu

This handy and smart feature saves battery life for laptops and tablets by temporarily changing system settings such as display, system cooling, system updates, and Bluetooth connectivity.

Security

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

Anti-tracker 

The anti-tracker extension blocks trackers that collect your data and allows you to view and manage this information on every website you visit. It keeps your browsing data private and improves performance by loading web pages faster.

Microphone Monitor

Take back control over your own devices with Microphone Monitor. Use it to see which apps have access to your device's microphone and when.

Webcam Protection

Protect your privacy and prevent webcam leaks. Webcam Protection alerts you when applications try to access your webcam and helps you block unauthorized access.

Secure Internet Banking

Bank and shop from a unique, private browser that secures your transactions to prevent fraud. Bitdefender Safepay can now also autofill credit card information in billing fields.

Parental Control

Parental Control offers digital assistance for parents and extra online security for children. Filter inappropriate content and limit screen time. Log in to Bitdefender Central remotely to monitor your children's online activities.

Privacy Firewall

With Bitdefender Internet Security, you get a strong layer of network protection so your personal information stays safe from hackers and data snoopers.

Wi-Fi Security Advisor

Wherever you connect, evaluate the security of your Wi-Fi network and router.
