Bitdefender Internet Security 2026 - Security for Your Online World

Protect yourself like the experts.

With Bitdefender, you benefit from the most innovative technologies capable of anticipating and preventing even the very latest cyber threats. Bitdefender software prevents, detects and eliminates online threats regardless of where in the world they originate.


Windows Protection:
Bitdefender's unmatched multi-layered protection protects your devices from all new and existing threats.

Comprehensive real-time protection for your data
Unrestricted control with the most effective malware protection on the market. Bitdefender Internet Security fends off all digital threats, whether viruses, worms and Trojans or zero-day exploits, rootkits and spyware. Your data and privacy are comprehensively protected.

Network threat prevention
Bitdefender Internet Security stops the detection and defence of online threats. Its new cyber threat intelligence technologies can detect and investigate suspicious activity at the network level. They block even the most complex exploits and malware, as well as brute force attacks and URLs associated with botnets.

Advanced threat defence
Bitdefender Internet Security uses behavioural detection technology to closely monitor your active apps. If the software observes suspicious behaviour in the process, it immediately springs into action to prevent infections.

Multi-layered ransomware protection
Bitdefender's multi-layered approach to ransomware protection includes a Data Protection layer that reliably protects your documents, pictures, videos and music files from any ransomware attack. Together with the Advanced Threat Prevention module, it protects your most important files from ransomware encryption.

Vulnerability Assessment
Scan for security holes and vulnerabilities with just one click. Bitdefender scans your PC for outdated and vulnerable software, missing Windows security updates and potentially insecure system settings and suggests optimal solutions.

Surf protection
Our web filters prevent you from finding yourself on malicious websites. Find out if it's safe to access your search results before you even click on a link. Bitdefender Internet Security also blocks all known infected links.

Anti-phishing
Online fraud is on the rise, but our advanced phishing protection conveniently protects you from all threats. Bitdefender Internet Security finds and blocks supposedly legitimate websites whose sole purpose is to steal financial data such as passwords and credit card numbers.

Anti-fraud
Advanced filters warn you in time about potentially fraudulent websites.

Spam protection
Filters irrelevant messages in your inbox and is available for local email clients (Microsoft Outlook, Thunderbird).

Safe Files
With Bitdefender's Secure Files you can prevent unauthorised access to your most important files. Simply add your folders to the watch list to protect them from ransomware and other types of malware. Afterwards, only applications that you have classified as trusted can access your Secure Files.

Rescue mode
Complex viruses such as rootkits must be removed before Windows starts. If Bitdefender Internet Security detects such a threat, it restarts the computer in rescue mode to perform cleanup and recovery.

Windows - PC Performance:
Bitdefender security software responds promptly and reliably to malware without affecting your system's performance.

Auto-Pilot
Bitdefender Autopilot now acts as a "security advisor" to provide you with even more comprehensive information about your security situation. Its intelligent features allow it to suggest security measures in line with your system's needs and your usage patterns.

Bitdefender Photon™
This innovative and unique technology allows Bitdefender Internet Security to adapt optimally to the hardware and software configuration of your system. This conserves system resources and increases system performance and speed.

Global Protective Network
Because the computationally intensive scans are performed in the cloud, the impact on your local resources is virtually zero. So you don't have to accept any loss in your system speed or performance. And the confidentiality of your data is maintained at all times: Bitdefender does not scan the actual contents of your files, nor are they ever uploaded or stored in the cloud.

Game, movie and work mode
Bitdefender Internet Security recognises whether you are playing games, working or watching a movie, so it knows that you don't want to be bothered with unnecessary requests. So you can concentrate on the important things in life. Depending on how you use your devices, Bitdefender stops pop-ups, adjusts graphics settings and pauses unimportant background activities so you can enjoy your device to the fullest.

Battery management
This useful and smart feature extends laptop battery life by temporarily adjusting various system settings such as display, system cooling, system updates and Bluetooth connection settings.

Windows Privacy:
Bitdefender's comprehensive security solution ensures that your privacy and data are protected online.

Hotspot protection
With Bitdefender VPN, you never have to worry about your privacy online again. Your online activities are protected by encrypting all traffic. With Bitdefender Internet Security, you get up to 200 MB of encrypted traffic per day on your Windows, Android, macOS and iOS devices.

Anti-Tracker
The Anti-Tracker extension blocks trackers that collect your data and allows you to view and manage this information for each website you visit. Anti-Tracker lets you browse privately and allows websites to load faster.

Microphone monitoring
This puts you back in full control of your devices. You alone decide which apps are allowed to access your device's microphone and in which situations.

Webcam protection
Protect your privacy and prevent your webcam from spying on you. The webcam protection informs you immediately about attempts to access your webcam and blocks unauthorised access.
