ESET Antivirus comes with all the security tools that you may ever need to protect your data and privacy, including:

  • Anti-theft support
  • Webcam protection
  • Intuitive setup and UI
  • Multi-platform support
  • Banking-level encryption
  • Low system requirements
  • Advanced anti-malware protection

An antivirus program needs to be fast, efficient, and cost-effective, and this one has them all.

The world is digitizing at a head-spinning pace and a couple of dusty drawers or shelves no longer qualify as reliable storage alternatives.

Instead, modern storage systems such as NAS devices and Cloud solutions accommodate our most sensitive files and data. Thus, deploying an antivirus for NAS storage makes perfect sense to security-mindful and privacy-conscious users.

Needless to say that NAS devices are far more secure than a paper file and they boast all kinds of defensive mechanisms from encryption services to backup solutions, firewalls, DDoS protection, and so on.

But the very nature of the information they house makes them a particularly enticing prize for profit-hungry hackers prowling for new targets to exploit.

And let’s not forget they are physical devices after all, prone to hardware malfunction and failure, manual tampering, and many other risks.

Now, we are not trying to diminish NAS devices’ security enhancements, but merely to emphasize that there is no such thing as too much protection when it comes to cyber threats.

So, just how secure is a NAS? Is NAS safe from hackers? Let’s find out together.

Can NAS be hacked?

Unpatched IoT gadgets are high-profile targets in regards to the valuable information they hold and NAS devices make no exception, regardless of the brand.

Take, for instance, the QNAP NAS. It has a long record of ransomware-based attacks exploiting vulnerabilities in outdated firmware, unsecured ports, and so on. Needless to say, it is essential to secure these devices using a reliable antivirus tool specifically designed for QNAP.

While we’re at it, you can also have a look at these best QNAP NAS backup software programs just to be on the safe side. After all, not putting all eggs in the same basket has proved effective so far in the most diverse of scenarios.

But most hackers cannot be bothered with such sophisticated methods. The truth is, the most common way to compromise a NAS is by a brute-force attack.

Sinology, for instance, another immensely popular NAS provider has known its fair share of large-scale attacks based on weak credentials combinations. And the list could go on and on.

Sticking to sensitive security policies such as strengthening your passwords, using encryption tools, multi-factor authentification, or not opening too many ports or connections is always a good idea.

But is it enough to keep your data safe? As you can see, the dangers lurking on the Web are far greater than a few random hackers targeting individual gadgets.

Since there are threats that do not aim to leverage specific vulnerabilities, your device would benefit from a network-wide security solution, capable to repel diverse attacks, from phishing to ransomware, malware infections, and so on.

The best way to add another layer of security is by deploying a good antivirus for Network Attached Storage.

Can you install antivirus on NAS?

You can and by all means, you should. There are a handful of security programs specifically designed with storage protection in mind.

Now that that’s out of the way, let’s see how he chose the best antivirus for NAS storage in the first place. Our experienced testers thoroughly scanned the market and compiled this selection of top antivirus solutions for storage devices.

They highlighted that cross-platform compatibility and high scalability are key factors when choosing a security software to safeguard the digital assets stored on a NAS.

As you probably know, not all NAS devices run on the same OS. Some popular alternatives such as QNAP gadgets run on different Linux-based distributions, while others rely on the good old Windows.

If you’re a home user, scalability will not be essential for you since a NAS already delivers plenty of storage space for your files, photos, videos, and so on.

However, things are entirely different when entering the enterprise segment and our guess is, you’d want a solution that is able to grow along with your workforce and secure your thriving corporate data.

As always, personal expectations and habits will shift the balance in one direction or another, but we can all agree that airtight security and good performance are not areas on which you’d want to compromise. So, here goes.

How do I protect my NAS?

How do I protect my NAS?

A sain routine implies sticking to some basic cybersecurity guidelines and this includes credentials and overall network protection. Start by changing the default passwords and go for strong credentials that won’t be easily compromised by brute-force attacks.

Speaking about password policy, it’s best to use multiple factors authentification in order to make sure your data is beyond hackers’ grasp.

Since staying off the grid defeats the purpose of owning a NAS – as in Network Attached Storage – you should secure your connection and network the best you can.

This implies using a traffic encryption tool, deploying a firewall, activating SSL certificates on your NAS to enable HTTPS connection, and securing ports.

Security often calls for tough choices. Thus, some settings may need to be activated, while others (generally the ones you do not use) simply have to go in order to leave as few exploitable loops as possible.

As always, outdated firmware is a recipe for disaster, so make sure your download and install all updates as soon as they become available in order to pump those security patches into your NAS.

Finally, it’s smart to combine NAS storage with performant antivirus software to keep out malware in the first place and you have a solid selection to help you out right here.

Don’t forget to use strong encryption as well as backup services to secure your valuable data against ransomware.
