Top 10 Antivirus Software Companies

From data protection to threat detection, Cyber Magazine considers some of the best antivirus software companies who are committed to protecting businesses

Ensuring that there is good antivirus software in place is a crucial step for businesses to prevent data breaches and cyberattacks.

Antivirus software aims to detect criminal activity on a device and delete or quarantine it. Cyber attacks in particular have exploded in 2023, with an increase of 60% having been reported earlier in the year. In an ever-evolving workplace where hybrid operations are the norm, companies are increasingly advised to look for better services that benefit their operations.
