Bitdefender offers robust 24-hour protection for up to five devices, with a suite of features including antivirus, firewall, VPN, and password manager. Our tech critic, David Phelan, put the Ultimate Security package to the test on Windows, Mac, and mobile devices, assessing installation, performance, and overall value.
Installation and Setup
Installing Bitdefender is straightforward. After creating an account and completing payment, users download a file from Bitdefender Central, the main dashboard. On Windows, closing all browsers may be required to finish installation. The first scan begins within minutes, though its duration varies: on a Mac with many files, it took just over an hour; on a PC, it was quicker. On macOS, Apple’s permissions require extra clicks for full disk access, but the process is clearly guided. Adding additional devices to the five-licence plan is simple—log in and download on each new machine, with QR codes facilitating mobile setup.
Performance and System Impact
Bitdefender lives up to its claim of a light touch. Even during active scans, resource usage is minimal, so users can continue demanding tasks like gaming without lag. The program intelligently pauses non-critical activities when the system is under heavy load. In testing, no noticeable slowdown occurred. The first scan on a Mac identified and resolved 14 issues out of millions of files, providing peace of mind without excessive false positives.
Core Antivirus and Threat Protection
At its heart, Bitdefender’s antivirus engine is consistent across all versions, including the free tier. The paid packages offer non-stop AI-powered protection. The dashboard suggests improvements like scam protection and chat protection, which scans WhatsApp and Telegram messages for phishing. The program effectively guards against a wide range of threats, with rare false positives.
Additional Features Across Tiers
Bitdefender offers several packages: Antivirus Free (single device, basic protection), Total Security (£84.99/year, £49.99 first year), Premium Security (£99.99/year, £59.99 first year), and Ultimate Security (£119.99/year, £69.98 first year). All paid versions include a password manager that works across platforms, a VPN (limited to 200MB/day on Total Security, unlimited on Premium and Ultimate), and support for five devices. Premium adds email protection for two addresses (Gmail or Outlook) and an anti-tracker that displays tracker counts on toolbar buttons. Ultimate includes identity protection scoring and continuous dark web monitoring.
VPN Performance
The built-in VPN is easy to set up but felt slightly sluggish compared to dedicated services like NordVPN, which did not slow traffic. However, for users without a VPN, Bitdefender’s version is a useful addition for secure browsing on public hotspots and accessing region-locked content.
Value and Recommendation
For most users, Premium Security hits the sweet spot, offering unlimited VPN and email protection for only £15 more per year than Total Security. Ultimate adds identity monitoring for those seeking comprehensive coverage. Bitdefender’s outstanding track record in independent tests and its minimal system impact make it a top choice for antivirus protection, with the extra features providing added value.
