Buy Bitdefender – Total Security & Antivirus Plus Licences

For years Bitdefender has consistently achieved excellent results in independent antivirus evaluations such as those by AV-TEST, AV-Comparatives and SE Labs. The Romanian security specialist combines outstanding detection rates with one of the lowest performance impacts of any antivirus solution tested – maximum protection without slowing your system down. At Lizenzindustrie you get Bitdefender as a verified licence with delivery by email – noticeably cheaper than buying from the manufacturer.

Why Bitdefender? – Its strengths at a glance

It is no coincidence that Bitdefender is one of the antivirus products most often recommended by IT professionals and security experts. The Romanian manufacturer's strengths are clearly defined and have been confirmed time and again in independent tests:

High detection rates: In independent tests Bitdefender regularly detects almost all known and new threats. Its multi-layered protection architecture combines signature-based detection, behavioural analysis and machine learning for comprehensive protection.

Minimal performance impact: Despite its intensive protection features, Bitdefender has barely any measurable impact on system performance. In AV-Comparatives performance tests Bitdefender is regularly among the most resource-efficient antivirus solutions of all – a decisive advantage for users who do not want to compromise on PC speed.

Photon technology: Bitdefender's proprietary Photon technology learns how an individual system is used and optimises scanning processes accordingly. Over time, Bitdefender becomes faster and more efficient on your own system.

Anti-ransomware: Bitdefender's multi-level ransomware protection is one of the strongest solutions on the market. As well as behaviour-based ransomware detection, Bitdefender also offers a remediation feature – files that have been encrypted can be restored automatically.

What does Bitdefender offer in detail?

Real-time protection with a multi-layered protection architecture – signature-based, behaviour-based and AI-powered. Threats are detected and blocked at several levels before they can do any damage.

Advanced Threat Defense monitors the behaviour of all active processes in real time and detects malicious behaviour immediately – even from previously unknown zero-day threats with no existing virus signature.

Safe Files protects important documents, photos and videos from unauthorised access by ransomware and other malware. Only trusted applications are allowed to access protected folders.

Anti-Phishing & Anti-Fraud detects and blocks phishing and fraudulent websites in real time – right in the browser, before any personal data can be entered.

Bitdefender VPN is included in the higher-tier packages and encrypts your internet connection for safe, anonymous browsing – with a daily data limit in the basic version or unlimited in the Premium packages.

Password manager stores and manages all your passwords securely – including auto-fill in browsers and automatic detection of weak or reused passwords.

Webcam protection detects and blocks unauthorised access to your webcam – important protection against stalkerware and RAT Trojans that secretly activate webcams.

Anti-tracker blocks tracking cookies and advertising trackers in the browser – for greater privacy online.

Frequently asked questions about Bitdefender

What is the difference between Bitdefender Internet Security and Total Security?

Bitdefender Internet Security is for Windows only and, in addition to complete virus protection, offers a firewall, parental controls, webcam protection and anti-spam. Total Security extends this to Windows, Mac, Android and iOS with a single licence and adds performance optimisation tools. For users with several devices on different platforms, Total Security is the better choice.

Bitdefender impresses in independent tests with its combination of a very high detection rate, minimal performance impact and a broad feature set. Its multi-layered protection architecture of signature-based detection, behavioural analysis and machine learning ensures comprehensive protection – including against new, unknown threats.

How many devices can I protect with Bitdefender Total Security?

Bitdefender Total Security is available for 5 or 10 devices – usable on Windows, Mac, Android and iOS at the same time. So one licence protects the family PC, the Mac laptop, the Android smartphone and the iPad simultaneously.

Yes. From Bitdefender Antivirus Plus upwards, a VPN with 200 MB per day is included. In Bitdefender Premium Security the VPN is unlimited – with no data cap.
