Secure file sharing has protected global storage and improves confidence with external partners
The best features Antivirus for Amazon S3 offers include that it is really a built-in feature which is really great, as you don't have to do anything extra, there's no operational complexity or cost overhead associated with it, and because it's a managed solution, it's easy for us to configure policies as S3 buckets are created globally and make sure they have the necessary virus protection as needed. The simplicity and ease of policy configuration have helped my team day-to-day because, as it is part of the AWS ecosystem, I don't need to really hire a separate skill set to configure this service, and moreover, if I use the console, all the features are available to me at a click, and I can also programmatically control it, making configuring the antivirus part of setting S3 objects rather than setting up a separate service altogether on top of S3.

Overall, I would evaluate the Microsoft support level that I receive at probably about a seven, but that depends on the day. It has been spotty. We have had issues where the urgency level of the Microsoft support is not as high as ours, especially during a data breach or potential data breach situation. We have had issues with some of the offshore support being lackluster. One specific thing that comes to mind is we were on a support call with our CISO on the call, and the Microsoft agent, who did not actually work for Microsoft, is one of the vendors that Microsoft uses for support, said, "Just to set expectations, my lunch break is in an hour and I am going to go away then." For us, it was already ten o'clock at night and we had been working on this for a couple of hours, trying to get a security engineer on with us. For him to tell us that he was going to go away and have lunch, it was, "Okay, but go find somebody else if you need to." It was just the lackluster approach, and it seemed like he did not really care. We seem to get a lot of this when we get non-Microsoft support. I can identify areas for improvement with Microsoft Defender for Endpoint, as it is kind of a convoluted mess to try to take care of false positives. Especially when they have been identified as false positives but they keep going off over and over again. It is great for my pocketbook because it generates a lot of on-call action, but I would really prefer more sleep at two o'clock in the morning than dealing with false positives. I would say that the unified portal for managing Microsoft Defender for Endpoint is suitable for both teams as they are all in there. It would be great if they would stop moving things around and renaming things, which makes sense. The new XDR portal is pretty nice. Being able to have it central again inside of the regular Security Center without having to open up two windows is helpful. Overall, I think it is pretty good. There is always going to be something that could be improved, such as alerting and the ability to modify alerts would be a little bit helpful to have. Being able to add more data into the alerts and turn off alerts that are not as useful would be beneficial. It is hard to say what the quantitative impact the security exposure management feature has had on our company's security, because a lot of it is kind of subjective. I think we are sitting at around a fifty percent score still, and a lot of it is just kind of unusual circumstances that we cannot really implement without breaking the organization.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Antivirus for Amazon S3 is a great tool that is reliable and easy to integrate, adding an essential security layer for S3-based workflows which may be subject to malicious attacks and protecting the overall infrastructure while also reducing the burden of checking those files on your own."
"Antivirus for Amazon S3 offers some of the best features including deployment using Terraform, the ability to scan new and existing objects, very quick setup time, multiple engine support such as Sophos, CIS Premium, and CIS Secure, and extensive vendor support through many marketplaces."
"Antivirus scanning has a clear positive impact on security, automation, and developer velocity in my organization."
"In my experience, the best feature Antivirus for Amazon S3 offers is increased security."
"Antivirus for Amazon S3 has positively impacted my organization by giving us the confidence that we can really expose our S3 buckets to the external world without having to worry about security, and from a developer standpoint, we know that at any point in time globally if S3 buckets are created, we have templates that will automatically enforce the antivirus policies there, improving our overall security posture rather than compromising it because we do have a large footprint on S3."
"Microsoft covers every aspect of security and the global challenges we face."
"Defender's analytics are much better than CrowdStrike's."
"The pros of Microsoft Defender for Endpoint are that it's simple to deploy and has all the required functionality."
"The most valuable feature of Microsoft Defender for Endpoint is that it is embedded into the Windows system. Additionally, the performance is good and simple to maintain."
"With its intelligence and tools over cloud infrastructure, it's a good product."
"Endpoint's most valuable feature is deep analysis."
"The product is very good when it comes to vulnerability assessment and, as a Microsoft flagship product, it integrates with Office 365, Azure, and Windows Server, offering far superior attack identification compared to Symantec."
"What I found most valuable in Microsoft Defender for Endpoint is that it's out-of-the-box, which brings more value to the customer."
 

Cons

"Integration, support, and documentation are areas where Antivirus for Amazon S3 has room to improve."
"Antivirus for Amazon S3 could be improved by addressing that it is a little bit complicated to set up because you have to deploy it via CloudFormation or Terraform, and it can be a little bit difficult trying to troubleshoot the image or container issues."
"The reporting part could be a bit more detailed."
"I think Antivirus for Amazon S3 could be improved by slightly further automating the process; beyond just the ability to send notifications, if an email could be crafted or if communication through any channel could be established with the person or team who uploaded the file, that level of automation could be avoided on our end, allowing us to configure an entire loop from detecting a malicious upload to contacting the uploader and taking corrective action, which I think would be really cool."
"I think Antivirus for Amazon S3 can be improved by including patches over time and adding forensic analysis of data to show where viruses may have been incorporated."
"Auto recovery is the most important feature that we would need from this solution. For decryption, similar to Malwarebytes, there should be something to be able to recover the data up to the last normal status. Its ability to recover data to the last normal copy must not exceed 5 to 10 minutes."
"Threat intelligence has the potential for improvement, particularly by integrating more sources."
"Additional security would be beneficial."
"I would like to see fewer pop messages and alerts. It's disturbing when you have that many alerts."
"The solution can be more user-friendly."
"When compared with other vendors, the pricing is very high."
"I think Microsoft needs to improve some of the security aspects of Defender. The email part, in particular, needs to be improved in terms of security effectiveness."
"The time it takes to restore the application could be improved. It has a lot of dependencies. It's not like the Microsoft security that comes with the OS. Updating through the command prompt, most of the time, it takes some time to download some of these dependencies."
 

Pricing and Cost Advice

"The cost is high, compared to other products in the market, if you look at it as a separate product. If you look at the cost where it is part of a bundle, the cost is okay."
"There is not a license required for this particular solution."
"The license for Microsoft Windows covers Microsoft Defender for Endpoint."
"It is free."
"Given our extensive Microsoft licensing, transitioning to Defender for Endpoint did not affect licensing costs."
"Its price is fair. It has approximately the same price as the other products such as Kaspersky. It is much cheaper than Malwarebytes."
"Pricing can always be lower."
"This is an expensive product and licensing for all Microsoft products is a big issue."
