Setup Cost

Antivirus for Amazon S3 offers cost-effective, scalable pricing at $49/month for 100GB, streamlining costs via AWS Marketplace.
MetaDefender's extensive security justifies its high price, with better value than competitors; custom quotes are recommended.
Generally in this case, the more we consume, the better the pricing gets with time.
Sr. Enterprise Architect at a educational organization with 501-1,000 employees
This leads to an average of 200 to 300 notifications of malware per month globally, which gives us confidence that the antivirus is working.
Senior Manager at Deloitte
I know in the AWS documentation, the pricing is always quite clear, and due to that, I have had no issues.
Cloud Ops Lead at a tech vendor with 10,001+ employees
When someone attempted to buy from us one instance of OPSWAT, it was about nine thousand dollars for multi-scanning with eight engines and also the CDR module.
Cyber Security Architect at Diffiesec
The price varies based on deployment types; we only used it for file transfer and cloud integration rather than email, which kept it within our budget.
Senior Associate at a educational organization with 11-50 employees
Regarding pricing, setup cost, and licensing, I find the pricing for kiosks, cloud, deep CDR, and adaptive sandbox appropriate.

Valuable Features

Antivirus for Amazon S3 offers automated malware detection, real-time scanning, and compliance support, enhancing security and efficiency.

It adds an essential security layer for S3-based workflows which may be subject to malicious attacks and protects the overall infrastructure.

The fact that the scanning occurs within the AWS account means data never leaves your AWS account, which is also a good security feature.
Cloud Ops Lead at a tech vendor with 10,001+ employees
Event-driven scanning stands out because it makes the entire workflow real-time and automatic.
configuration and management deployment at a tech vendor with 10,001+ employees
I believe this is very effective and is the most effective engine of OPSWAT because customers ask for OPSWAT for two main reasons: the CDR capabilities and the multi-scanning engines.
Cyber Security Architect at Diffiesec
MetaDefender's core philosophy of trusting no file means it scans files, rebuilds them, and verifies their reputation, ensuring they contain no malicious content.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
The integration of multi-scanning and Content Disarm and Reconstruction is truly helpful because we can utilize it in other products such as email integration with ICAP capability, and we are also using it in web scanning.

Featured Reviews

Kalpesh Potghante - PeerSpot reviewer
Senior Manager at Deloitte
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.

File protection has improved and now keeps millions of daily transfers secure and compliant
In my organization, while using this tool, we found that there were a few files flagged as suspicious; however, those were not suspicious and it was a false positive, so that can be improved. False positive results were an issue, and it took time to scan files if the file size was greater than 1 GB. For larger files greater than 1 GB, it needs to be improved. In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective; however, in other types of files, it was very effective and could scan files properly. We have already covered all the main suggestions; however, it can be improved to reduce false positive results, and scanning could be faster to process more files in a day.
