Additionally, Microsoft defender has a seconder layer of protection in all its controlled features. It is definitely free. Cons Like all Microsoft products, Microsoft defender has its eccentricities. When it comes to the latest threats and malware, it is not the most updated antivirus software in the market. It also lacks additional tools which other party antiviruses uses like VPN, password manager, dark web monitoring or identity theft protection. In as much as Microsoft defender is closer to been competitive with other third party protection software’s, I feel it still has a lot of room for improvements.
