Recommended Security Software for Windows, macOS, and Linux

This article is intended for clients who want to improve the security of their personal computers or workstations.

While our servers and hosting environment are protected by multiple layers of security, it is equally important to keep your local device secure to avoid malware infections, data theft, or unauthorised access.

We recommend using reliable anti-virus, anti-malware, and firewall software on your operating system. Below are some of the most efficient and widely trusted solutions for Windows, macOS, and Linux, based on recent independent test results from AV-TEST and AV-Comparatives.

Windows

• Bitdefender Internet Security / Total Security
  Consistently among the top performers in protection tests with minimal false positives. Includes a strong firewall and ransomware protection.

• Kaspersky Plus / Internet Security
  Excellent detection rates and real-time protection, with frequent recognition as a top product by AV-Comparatives.

• ESET Smart Security / NOD32
  Lightweight, strong detection, and low system impact, making it ideal for both personal and business use.

• Malwarebytes Premium (supplementary)
  Highly effective at detecting and cleaning adware, spyware, and zero-day malware. Best used alongside a main antivirus solution.

macOS

• Bitdefender Antivirus for Mac
  Offers strong real-time protection against both Mac and Windows malware, with very low performance impact.

• Kaspersky Plus for Mac
  Consistently tested as one of the stronger macOS security suites, with additional web protection.

• Intego Mac Internet Security X9
  Built specifically for macOS, providing antivirus protection and a smart firewall.

• Malwarebytes for Mac (supplementary)
  Excellent for removing adware and potentially unwanted programs that are common on macOS.

Linux

• ESET NOD32 Antivirus for Linux
  Provides strong protection with low resource usage, suitable for both desktops and servers.

• ClamAV (with ClamTk GUI)
  A free, open-source scanner widely used on Linux systems, especially for email and file scanning.

• Sophos Antivirus for Linux
  Offers enterprise-grade protection with real-time scanning and command-line controls.

For firewall protection on Linux, the built-in tools (iptables, nftables, or ufw) are usually sufficient, but advanced users may also deploy intrusion detection/prevention systems (IDS/IPS) like Snort or Suricata.

Additional Recommendations

• Keep your operating system and applications up to date with the latest security patches.

• Use a password manager to create and store strong, unique passwords.

  • You can find a list of recommended password managers in this article: Common Password Security Practices

• Enable two-factor authentication (2FA) wherever possible.

• Regularly back up important files to an external drive or a secure cloud service.

By combining trusted security software with good practices, you significantly reduce the risk of infection and unauthorised access.
