Microsoft Defender Antivirus Room for Improvement

Information Security Analyst at a financial services firm with 501-1,000 employees
There are certain features that do have room for improvement. I think with the analytics engine they're looking at it from the desktop and the server perspective. I think the desktop engine should also include the script analytics — what executed, what's the power shelf or UI commands, or some form of Splunk regex. I know we don't have that functionality with a run-time analytics platform, but it's a JS (JavaScript) based one. So it would be good if they had a regex to JS converter. The biggest problem is they need to take things out of preview. I know that they're developing on the platform service with the analytics engine, but so many services still rate it as a preview after 12 to 18 months, which is stopping adoption with businesses knowing that that solution could be filled and redirected at any time. So that delay is limiting technology to be able to be updated because they don't have to release all production support. View full review »

The product should keep updating its software as to counter incoming threats since threats are becoming more advance with time. The product should be strong in all parts. I would recommend if the product continues to be updated that the way it updates is faster for downloading and updating in our system. The stability is good and should continue to perform well in that way. With increase of cyber threats and cybersecurity issues, I would recommend that the product be developed like an AI product with more features which can counter any threat in the coming eras.

As I've only used the product for three months, I haven't really had time to explore the entire solution. However, I haven't found anything that is lacking just yet. Currently, we're actually behind on the current feature offerings and need to explore the system quite a bit more. It fits our needs so far. The pricing could be a bit better. View full review »

I would like to see online updates for patches for this solution. I would also like to see online information about what is trending in the market in terms of spams, viruses, or trojans. It takes some time to understand how this solution works. A few things are unclear at the beginning, such as whether it actually restricts the virus or spam at the initial stage, or when there is a security update, how will we come to know and how will it get synchronized. It would be really helpful if there is some kind of knowledge base in the form of video, audio, or document that can explain in a user-friendly way the setup, features, risks, and process to mitigate the risks. Currently, I have installed endpoint security for every individual system. I could not install it like other endpoint solutions where we have a server and a client. It would be really helpful if Microsoft Windows Defender has a server-client based model so that I can save some bandwidth when it downloads or uploads features. It will be helpful if we have a LAN-based or WAN-based controlling system. View full review »

Microsoft Windows Defender doesn't have a game mode. Other antivirus software (like BitDefender) have something known as a game mode. If you want to play a game, just enable the game mode to allow certain traffic without needing to configure it. Windows Defender doesn't have that. There's no Windows Server edition for Windows Defender as part of the distribution. View full review »

I'm sure the premium product has extra features, like listing questionable websites. Defender is just an antivirus product. It would be nice to have a paid upgrade that would provide additional screening of the day-to-day activities. View full review »

Windows Firewall is integrated with Windows Defender. Over the last few days, I have had a problem with defining a wildcard on Windows Firewall. For example, I wanted to pull out the connection of my program and install a software package with a lot of executable files. I wanted to prevent it from accessing the internet. I could not select executables by using a wildcard. I had to select a single executable with its full name. View full review »

There were a few detections that are not picked up, and then Microsoft picks up on that and they update it. That's just a normal thing you go through based on every antivirus solution. You're always going to have viruses and signatures that are coming out. So, I wouldn't say it's the perfect solution because if you're looking at next-generation behavioral based things, for example, if you're going to use ATP, that's when you can get more methods out of it. With Defender, if you pay more you can get the ATP component, which is sold separately by Microsoft. We do have some challenges in the reporting aspect of it. There's a lot of manual effort involved to configure what we need. There are also a few issues with policies. View full review »

The solution needs to improve its ransomware. It's not so good. It could also use some general performance optimization for the computers the solution operates on, to ensure it does not slow down the devices. View full review »

I think the console can be better. The end-user also cannot do some advanced actions on it. It's a little bit complicated for our end-user, so it needs to be simplified. I think the solution is complicated. This one is one of the concerns that I like to talk about because some end-users do not know how to navigate through the console and how to work with them. I think this is not such a big deal, but I know that there will be other things that may be important to us like, how we can centrally manage users and reports are really important for us. For example, in Kaspersky, we had a problem where we couldn't detect the attacks that we had in some of our zones in our data center. I think if Microsoft Windows Defender can report these things, it's going to be great. View full review »

One area of improvement for this solution is to have a faster turnaround time on updating definition files. Since there are usually various ransomware variants, this solution may not pick it up in time like other commercial antivirus solutions. However, we have not encountered an issue like this yet with definition updates. With regards to the interface, a challenge I found was that there was not enough documentation on how to tune it. I had to read multiple sources on the internet to learn how to configure the tool appropriately. In the next release, I would like to see the solution have a backup feature were my data could be saved to a Microsoft OneDrive account or an equivalent cloud platform so that, in the event of a ransomware or malware attack, I can easily retrieve my data.

This solution is not perfect. Sometimes it detects something and it's not a threat. The good news is that you can restore something and analyze it better and you can restore the file and copy it or disable the defender and run it again. The system can always be simplified and have a better integration check. More detailed reports would be good. When it does the integrated check, it just shows if the system is okay but I want to know what happened. View full review »

I do not find that there is very much about it that needs to be improved. Everything can be cheaper I am sure. So, it could be less expansive. View full review »
