Alternatives to Bitdefender
Top lab scores, light footprint
Bitdefender ranks #1 of 9 in Antivirus software, with an Alt Score of 91. It is freemium from $24.99/year and available on Windows, macOS, Android and iOS. 10 of 10 checklist rows are verified against a public source.
Individuals and families wanting antivirus and privacy protection across their devices, plus small businesses and enterprises needing endpoint security and threat management for their networks.
Real-time antivirus and malware protection, ransomware and phishing defense, plus firewall, VPN, and parental control add-ons for consumers. Business customers get endpoint detection and response (EDR/XDR) through the GravityZone platform, with centralized threat monitoring and attack surface reduction. Detection relies on signature-based scanning plus behavioral and cloud-based threat intelligence.
You install the Bitdefender client (consumer app or GravityZone agent) on each device, which then runs continuous background scanning and real-time monitoring against Bitdefender's cloud threat database. Detected threats are automatically blocked or quarantined, with alerts and management surfaced through a local app or, for business tiers, a central management console.
