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.

Multi‑engine detection has significantly improved secure file transfers and threat prevention
Some feedback indicated that it takes too much time to configure certain policies because there are many options. Some people appreciate this because you can configure anything, but I believe MetaDefender should have a wizard or general policies that can be used for 80 percent of customers. I use the expanded file type and archive coverage feature sometimes, especially for customers who try to scan large archives with the deep scan capabilities of OPSWAT and Deep CDR. This provides full protection because it scans every single file, but sometimes it takes too long. When discussing CAB files or archives for patching or server updates and BIOS updates and operating system updates, the scanning process takes too long, and it was difficult for customers who sometimes decided not to scan because the scanning time was excessive. I use the reporting and audit visibility features. Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand. If something requires checking and then referring to documentation to understand it, that is too much for most users. When looking at one of the statistics, you can see how many files have been scanned and then you see a number out of 500 or a different number if you change it. It is not a number of files or scan processes; it is a number of files inside a file. When you scan a PowerPoint presentation file, for example, it counts as forty different files because of all the sub-files. I understand from customers that when they look at the visualization data or statistics, they do not understand what is happening there. Most customers I see do not use the file-based vulnerability assessment feature. It has some good results about vulnerabilities, but I am not certain if it is that helpful because many organizations, when they deploy a file and see that there are vulnerabilities, still deploy it because it is part of the code. It can produce results, but those results do not cause any action. Many products have something more advanced than vulnerabilities and static scoring. They have tools that can inform you about a vulnerability, whether the vulnerability is exploitable, if it is weaponized, and if someone can use this vulnerability in your environment. The file-based vulnerability feature works, but for most people, they do not take any action based on the results or block files because of file-based vulnerabilities.

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 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."
"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."
"I like the simplicity, the way it works out of the box. It's pretty easy to run and configure. The integration of the network devices with the ICAP server was easily done."
"OPSWAT is the best alternative."
 

Cons

"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."
"The reporting part could be a bit more detailed."
"Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand."
"The documentation is not well written, and I often need to talk with support."
 

Pricing and Cost Advice

"We bought a three-year license, and that was pretty expensive. We agreed that it was really worth buying. It could be cheaper, but we understand that quality comes at a price."
