Room For Improvement

Antivirus for Amazon S3 needs better large file handling, AWS integration, error diagnostics, and automation for improved functionality.
MetaDefender needs faster scanning, improved UI, better documentation, reduced false positives, easier setup, and more affordable pricing.
Allowing us to configure an entire loop from detecting a malicious upload to contacting the uploader and taking corrective action.
Senior Manager at Deloitte
Overall, Antivirus for Amazon S3 is reliable and effective for securing S3 environments.
Team Lead, Technical Content Security at Valuepoint Systems
Granular controls represent another area for improvement. The current scanning policies apply bucket-wide. More fine-grained controls, such as scanning only certain file types, prefixes, or user uploads, would reduce unnecessary scans and improve efficiency.
Assistant Professor, Technical Trainer at DIEMS Chh.Sambhajinagar
MetaDefender should have a wizard or general policies that can be used for 80 percent of customers.
Cyber Security Architect at Diffiesec
Pricing is an important aspect in catering to customer budgets and is a must-have consideration for organizations.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
Enhanced reporting and audit capabilities are not fully utilized.
Project Engineer at i-Secure Networks & Business Solutions Inc.
 

Setup Cost

Antivirus for Amazon S3 offers predictable and reasonable pricing with effective malware detection, appealing to enterprise buyers.
MetaDefender offers costly multi-layer security, seen as competitive, with $145,000 for three years including servers and support.
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
Compared to traditional endpoint antivirus licensing, this approach saved us fifty thousand rupees annually in overhead.
Assistant Professor, Technical Trainer at DIEMS Chh.Sambhajinagar
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
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
Regarding pricing, setup cost, and licensing, I find the pricing for kiosks, cloud, deep CDR, and adaptive sandbox appropriate.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
feedback indicates that our pricing is better than other vendor solutions.

Valuable Features

Antivirus for Amazon S3 offers robust malware protection, enhancing security, efficiency, and compliance with seamless AWS integration.
MetaDefender offers comprehensive security with multi-engine scanning, sandbox analysis, CDR, file reputation, and seamless integration for enhanced data safety.
It adds an essential security layer for S3-based workflows which may be subject to malicious attacks and protects the overall infrastructure.
Dev Ops Engineer at a construction company with 11-50 employees
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.
Project Engineer at i-Secure Networks & Business Solutions Inc.

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 sanitization has protected critical networks and prevents hidden malware from entering
In my experience, the best features MetaDefender offers include the number of different antivirus engines that can scan files through multi-file scanning, often using 20 to 30 engines, with the top premium package around 33 engines, capturing 80 to 90% of malware in all those files. If any engine detects malware, the file is blocked, which increases detection because different engines catch different malware. When dealing with central government and defense, we find that if there is any kind of malware on the network or the file, whether that is a software file, hard disk file, or a pen drive, it cannot be allowed on the network. This is when we put it into the sandbox and perform file sanitization to ensure that nothing malicious comes into the network. Whenever we are dealing with central government or defense contracts, MetaDefender's core philosophy of trusting no file means it scans files, rebuilds them, and verifies their reputation, ensuring they contain no malicious content. This positively impacts our organization by detecting malware and stopping any kind of data leaks through the network. In terms of measurable outcomes across central government and defense, we are seeing saved time when files go through the antivirus file scanners. In financial services, such as with mortgage applications, the process sends files straight into MetaDefender file scanning that cleans out any malicious content.
