Security for everyone - Review ESET Smart Security Premium

5 out of 5 stars

ESET is one of the top security vendors in the world, and their products have been validated by many IT security organizations. Their most complete security solution is called ESET Smart Security Premium and, besides the usual antivirus engine, firewall module, or web shield, it also bundles additional tools that should make the product even more attractive. As we were curious to see everything ESET Smart Security Premium has to offer and how good it is for protecting our Windows computers and devices, we decided to test it for a while. Now we are ready to share with you everything we know about this product, so make sure that you read this review from top to bottom. By the end of it, you should have a good idea of whether ESET Smart Security Premium is right antivirus product for you:

What is ESET Smart Security Premium good at?

ESET Smart Security Premium is an antivirus product that is very good at:

  • Keeping you safe from malware, both offline and online
  • Protecting you against network attacks of any kind
  • Giving you a user interface that is both simple and easy to use, and with lots of advanced settings and detailed information, if you need it

ESET Smart Security Premium vs. ESET Internet Security

ESET Smart Security Premium is the most complete security product offered by the company and, compared to ESET Internet Security, it also includes the Password Manager and the Secure Data tools. If you do not have a subscription to LastPass or other similar password managing services, then ESET’s Password Manager is a must-have. If you work with sensitive files, encrypting them is a good way of keeping them safe. In the end, if you also take into consideration the rather small price difference, we believe that the ESET Smart Security Premium is the better buying choice.

Pros and cons

Here are some of the most positive features of ESET Smart Security Premium:

  • The antivirus engine is efficient and can protect you against any malware threats
  • The antivirus engine is very fast when scanning for malware
  • ESET has almost no negative impact on your computer’s performance
  • The user interface is easy to use and understand
  • The firewall module is highly efficient in protecting you against network attacks
  • Most of the security tools that are bundled provide additional value for their users

The less positive aspects are the following:

  • It can lower the speed of your network and internet transfers

Product Rated


ESET Smart Security Premium is a robust security suite, offering you a powerful antivirus engine and a highly efficient firewall module. To control what is under the hood, ESET Smart Security Premium offers a user interface that looks good, and it is also easy to use and understand. We liked the abundance of advanced settings that you can work with, and appreciated the minimal negative effect it has on your computer’s performance and speed - ESET Smart Security Premium is a lightweight and a fast security suite. The only thing that is not great about it is the fact that it can lower the speed of your network and internet transfers because it scans all your traffic for threats and malware. Also, we wished that this security product had a VPN solution bundled with it. However, ESET Smart Security Premium does offer many extra tools which you probably want: banking protection, parental controls, and a password manager. ESET Smart Security Premium is one of the best security products that we have tested, and we are confident it will not let you down either. We highly recommend it to all our readers.

The download and installation experience

Getting ESET Smart Security Premium on your PC starts with downloading a small executable file called eset_smart_security_premium_live_installer.exe. It has a size of only 4.05MB but, during the installation, it downloads another 180MB of files from ESET’s servers.

The installation wizard starts by asking you to select the language you prefer to use and to accept the EULA (End-User License Agreement). Then, you can enter your license details, purchase a new license or activate the free 30 days trial version. If you only want to test the product, you must provide the company with a valid email address, but that is all - no other personal details are required.

The installation wizard also allows you to choose whether you want to “Enable ESET LiveGrid feedback system” and to enable or disable the “detection of potentially unwanted applications.” We recommend that you enable the ESET LiveGrid feature, as it will allow ESET’s engineers to collect information about suspicious items and process them as quickly as possible. That can help make ESET’s security products react faster to new threats. We also believe that it is a good idea to enable the detection of PUPs (potentially unwanted applications). They may not be actual viruses, but they can be just as annoying.

Then the installation takes its course. When done, the security suite loads its user interface, and the first thing it does is ask if you also want to enable some of the additional security tools it offers: Password Manager, Secure Data, Parental Control and the Anti-Theft module. Some of these tools, like the Anti-Theft module, require you to create an ESET account.

At the same time, ESET Smart Security Premium runs its first virus signature database update. On our test computer, the first update meant the download of another 13.5MB of data, which is a small update compared to other security suites that are not so well designed. We also noticed that the security suite automatically started a full computer scan, right after the update was finished, which is a good thing because it means the system health is checked as soon as possible.

Downloading ESET Smart Security Premium on your computer is easy, and we like the fact that the only information you have to provide to activate the trial version, is your email address.

Integration with Windows, web browsers and universal Windows platform apps

ESET Smart Security Premium disables both the Windows Firewall and Windows Defender during its installation. This ensures that you do not encounter performance issues or software conflicts because of similar security products running at the same time.

The product is also well integrated with Windows and its networking features. We did not encounter any issues in accessing the shared folders on our local network or when downloading, installing or updating universal Windows platform apps. One thing that we noticed when we first installed ESET Smart Security Premium, and which we appreciate as positive, is the fact that the firewall module actively monitors the network profile you set in Windows and automatically adjusts its protection accordingly.

Regarding web protection, ESET Smart Security Premium chooses to filter the entire internet traffic that goes on your computer. It does not include any web browser extensions, and that is a good thing. Because it scans all the internet traffic, it means that you are protected just as well in any web browser you use.

Next, we checked whether all the processes run by ESET Smart Security Premium are protected against unwanted termination. We are happy to say that they are, so nasty malware will have a tough time disabling this security suite.

If you are worried about whether the security suite slows down your PC, worry not. On our test laptop, ESET Smart Security Premium used around 77MB of RAM, and the boot time we measured with BootRacer before and after installing the suite was the same.

To check whether the internet or local network speeds are affected by ESET Smart Security Premium, we also ran a few tests with and with LAN Speed Test. The tests that we ran with showed that the upload speed was not affected by the security suite, but the download speed went down by 23 percent. The tests we ran with LAN Speed Test showed that the upload speed for copying a file through the local network was slower by 13 percent and downloading was slower by 21 percent after installing ESET Smart Security Premium. This means that the security suite has a negative effect on network transfer speeds, and on internet data transfers.

ESET Smart Security Premium is a security suite that is well integrated with Windows and its networking features. We like the fact that the firewall module can automatically adjust its protection level according to the network profile you set in Windows, and we appreciated the almost nonexistent negative effect the security suite had on the performance of our test computer. However, we did not appreciate that it lowers the speed of your network and internet transfers.

Ease of use & configuration

The user interface offered by ESET Smart Security Premium mixes traditional and modern design, and the result is positive. You get a user interface that is generously spaced, with large sections and buttons. You also have switches controlling everything in and about. The essential tools and options are arranged into a few main sections on the left side of the window, while the details from the current section are shown on the right side of the window. On the dashboard, you get to see a large message about the current state of security on your Windows computer. If it is green, things are OK, but if it is red, there are urgent issues that you need to take care of.

As the user interface relies on using large buttons, tiles, and switches for most of the critical tools and settings, it is easy to use ESET Smart Security Premium even on devices with touchscreens.

Although most protection modules and tools can be configured by accessing each of them, if you want to get quick and easy access to all the advanced settings and configuration options, you can do that with a click or tap on the Advanced setup button from the bottom right corner of the Setup section. Inside the Advanced setup, you can change the way ESET Smart Security Premium works in every little detail.

Although ESET Smart Security Premium has settings and features that are well explained in context, if you encounter anything that you do not understand, there is a significant chance that it has a small i button on its right side. Clicking or tapping on it gives you additional tips and details. And if that is still not enough and you need even more support, ESET Smart Security Premium includes plenty of Help information and a good Customer Care section too.

When something important is taking place on your computer, or when your input or decision is required, ESET Smart Security Premium displays short and clear notifications on your desktop.

ESET Smart Security Premium also offers log files, visual protection statistics, lists with processes running on your computer and their reputation, details about the network connections present on your device and so on.

The user interface of ESET Smart Security Premium is well designed. It is easy to use and understand by beginners, but it is also full of advanced settings and detailed security information, which experienced users will surely appreciate. We like the way traditional and modern design meet and how simplicity and details intertwine.
