The best thing you can do to protect your privacy when working from home is to download a VPN and an antivirus. It’ll give you all-around internet security as it’ll hide your online data and make sure no malware sneaks through into your system.  You should also expand your cybersecurity knowledge, especially when it comes to phishing. It’s worth asking your employer if they would be willing to provide dedicated training at work. If not though, you can still find plenty of free resources, such as Udemy or Codecademy.
