Do you need an antivirus for Synology NAS?

Antivirus software is frequently installed and run on systems to keep malicious content out and you can also install it on NAS enclosures. Most NAS brands offer security software through their respective package managers. Synology NAS is very secure out of the box, so do you need an antivirus?

Not really, so long as you’re careful with what you use the best NAS for and configure your network accordingly. Features like uPnP are useful in making it easy to connect to your NAS from the outside world, but they can also make it easier for malicious parties to access your server.

I’ve not been using antivirus software on any of my computers for more than two decades. This isn’t because I feel as though the software has no place in 2022, but I feel as though I’m careful enough when browsing online and doublecheck when downloading content.

But just because I don’t believe the best Synology NAS would be easily affected by viruses, it doesn’t mean you won’t ever encounter one. Ransomware is a potent threat and affects all branded NAS enclosures. If you’re dealing with sensitive data or personal files, it’s important to ensure you’re running best security practices.

The same goes for running websites on the Synology NAS or downloading files from other websites or online sources. There are two antivirus suites from Synology, including its own free Essentials app and another that uses McAfee signatures. Most NAS, including Synology enclosures, run on Linux which makes it more difficult for viruses to take hold.
