    Automation has improved threat detection and reduced manual checks but pricing still needs work

    Reviewed on May 01, 2026
    Review from a verified AWS customer

    What is our primary use case?

    My main use case for Antivirus for Amazon S3  is to secure my S3  buckets in Amazon, which can easily be hacked. I want to secure it from malicious injections.

    How has it helped my organization?

    Antivirus for Amazon S3  has positively impacted my organization by reducing the number of people who need to monitor threats or malicious code injections. This solution replaces that manual monitoring and only sends alerts, so we do not need to wait or check every time if it is safe or if it is getting hacked.

    It has saved one or two people and saved almost 10% to 30% of the time. It also improved efficiency by almost 70%.

    What is most valuable?

    The best features Antivirus for Amazon S3 offers are zero maintenance, zero server maintenance, and the alerts. If you are a small company or small organization, you can also get a good file size. The setup time is very low compared to other solutions, which can take 15 minutes to half an hour, but it takes under one minute.

    It can easily be integrated with AWS . The alerts help my team because if something unusual occurs in our bucket or something happens that could not happen in the bucket, it will observe and understand the patterns sometimes and send us email alerts so that we can take a quick look at it and fix it immediately. The quick setup improves our workflow significantly.

    The integration of Antivirus for Amazon S3 is very good and easily integrated with Amazon AWS  because it is an Amazon AWS product.

    What needs improvement?

    Antivirus for Amazon S3 can be improved by implementing multiple buckets into one guard, enabling TBAC which can be automatically configured by Amazon GuardDuty, and adding multi-engine scanning.

    Regarding needed improvements, I think pricing is a bit higher for people who are using it very low and for small organizations. Large organizations who will use it more will benefit from the price, but small organizations will face significant monetary loss. I think they should reduce the pricing and put event-based pricing related to the organization size or the usage. I understand it is pay-per-use, but sometimes it does not make sense.

    For how long have I used the solution?

    I have been using Antivirus for Amazon S3 for the last six to eight months.

    What other advice do I have?

    My advice to others looking into using Antivirus for Amazon S3 is that this is good for medium and large-sized organizations, considering the price and what it offers. It can reduce some people, but for small organizations, I think people should be there sometimes to monitor it to save money. The people who do multitasking should be the ones who monitor as well to reduce more costs rather than relying only on GuardDuty. I give this product a rating of 7.

    Which deployment model are you using for this solution?

    Public Cloud

    If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

    Automated quarantine has reduced security risks and has removed manual incident handling

    Reviewed on Apr 27, 2026
    Review from a verified AWS customer

    What is our primary use case?

    My main use case for Antivirus for Amazon S3  is quarantine.

    A specific example of how I use Antivirus for Amazon S3  for quarantine is that we use it from the black box that can recognize viruses immediately.

    How has it helped my organization?

    Antivirus for Amazon S3 has positively impacted my organization as it has reduced time to market and secured our operations.

    There are no special specific improvements in my secure operations resulting from the reduction of time to market.

    What is most valuable?

    The best features Antivirus for Amazon S3 offers are advanced automatization and isolated quarantine bucket.

    The advanced automatization and the isolated quarantine bucket have helped my workflow and security because I do not need to write my own scripts on Python and Lambda to operate with incidents, which saves us a lot of costs.

    I think it is excluding the human factor of failure.

    What needs improvement?

    I think there is a problem with pricing while scaling, and it is a blocker for big corporations as there is a subscription for the instance plus volume of scanning.

    It would be great to have more understandable billing dashboards.

    For how long have I used the solution?

    I have been using Antivirus for Amazon S3 for more than five years.

    How are customer service and support?

    I rate customer service as 3 out of 10.

    What other advice do I have?

    My advice to others looking into using Antivirus for Amazon S3 is to connect it immediately without hesitation. I rate this review as 9 out of 10.

    Automatic file scanning has protected shared content and now requires richer, AI-driven checks

    Reviewed on Apr 24, 2026
    Review from a verified AWS customer

    What is our primary use case?

    As an API Integration Engineer, my main use case for Antivirus for Amazon S3  involves scanning partners' uploaded content that arrives via API. I deal with files that third parties push into S3 , such as media files like images or video files from channel managers or PMS partners that have API access to the Airbnb API source code.

    Antivirus for Amazon S3  fits into my workflow by triggering scanning automatically at some point, while at other times, I perform manual scans depending on the load of the files that partners push towards our API.

    In my main use case for Antivirus for Amazon S3, guests, hosts, and customer support agents eventually see these downloaded files, which may include malicious PDFs or host onboarding documentation that could feature a malicious customer support agent mechanism.

    What is most valuable?

    The best features Antivirus for Amazon S3 offers include native S3  event integration, which allows scanning to fire automatically, in-place scanning so files are not copied to another bucket, results attached as S3 object tags, IAM-based policy enforcement on scan results, large file support with streaming scans, archive and nested file scanning, multiple detection engines running in parallel, custom YARA rule support, quarantine or automated remediation actions, scan on demand, and retrospective scanning.

    In my day-to-day work, I rely the most on in-place scanning, as it is the best feature of modern Antivirus for Amazon S3 that does not pull objects out of the bucket for scanning. For example, older solutions required copying files to an EC2  instance for scanning, which was slow, expensive, and doubled our data egress attack surface.

    Antivirus for Amazon S3 has positively impacted my organization by making the entire organization much safer, allowing partners to safely upload their personal files, images, and videos to the Airbnb platform, which ensures that we as a company can be a reliable partner to our partners with safe integration.

    What needs improvement?

    I believe Antivirus for Amazon S3 can be improved by implementing some pre-writing features, such as synchronously scanning at the API layer.

    I would like to see improvements in content-aware scanning not just for malware, but also for other content, such as PDF files or API request parameters and strings, along with prompt injection scanning with custom AI agents creating the skill direction.

    For how long have I used the solution?

    I have been using Antivirus for Amazon S3 for two years.

    What do I think about the stability of the solution?

    Antivirus for Amazon S3 is sufficiently stable.

    What do I think about the scalability of the solution?

    I would rate its scalability as nine out of ten, as S3 is one of the most scalable services AWS  has built, providing a foundation upon which most other scalable AWS  services rely. However, it does not achieve a perfect score of ten due to real scaling cliffs when operating at high volumes that can catch you off guard.

    How are customer service and support?

    Customer support for Antivirus for Amazon S3 has always been straightforward, and since they are globally distributed, I would rate them nine out of ten.

    What was our ROI?

    I would say we have seen money saved and time saved on a long-term basis with Antivirus for Amazon S3, although we did not reduce employee numbers.

    After a couple of meetings with higher management, I believe there were negotiations, and the overall business terms were met, making my experience with pricing and compliance satisfactory.

    What other advice do I have?

    I would like to add that it would be beneficial to use AI as a parallel agent in the back end to fast-forward the malicious detection process for the large number of files being sent in various directions.

    I advise others looking into using Antivirus for Amazon S3 to check the pricing and determine if this service is something that their company or organization truly needs. They should consider the downsides and upsides, check incident level metrics, and evaluate their overall long-term budgeting, which will help in making a final decision.

    I would like to add that S3 is the gold standard for storage scalability and antivirus protection. Overall, it is a decent product. I would rate this review a seven out of ten.

    Automated threat response has protected our cloud data and has improved security efficiency

    Reviewed on Apr 19, 2026
    Review from a verified AWS customer

    What is our primary use case?

    My primary use case for Antivirus for Amazon S3  is protecting the data and files stored in the S3  bucket from malware or viruses. The solution scans the files to ensure they are safe.

    Antivirus for Amazon S3  has protected us many times. In a real scenario that I remember, there was access to an Amazon S3  bucket from unknown locations, including Russia and Ukraine. We immediately received an alert about suspicious account activity from unknown user locations, and an API call was activated. Once we received the alert, we quickly investigated and found that malicious Java code had been injected into the S3 bucket, which was causing infections when users downloaded it on their machines. The host was compromised, the AWS  account was compromised, and we got a real-time malware alert.

    What is most valuable?

    Antivirus for Amazon S3 protects our system by scanning files in real time and detecting viruses, malicious files, and malware, then taking comprehensive action for threat detection and protection.

    The best feature is definitely the deployment. The deployment takes less than 10 minutes. The solution runs within the AWS  account, ensuring the data remains secure and compliant. Automated threat mitigation is the second main feature. It automatically tags, deletes, and quarantines the infected file upon detection and provides robust defense against malware, protecting in real time.

    The system can automatically delete and quarantine the infected files once they are found to be malicious. This antivirus solution has a robust defense against malware, ensuring it never reaches the end user's S3 bucket and S3 locations.

    It has definitely impacted our business positively. It makes our complete S3 bucket and AWS account secure by ensuring that no malicious file can be uploaded or downloaded by any AWS account holder. All the data that is stored in the cloud is fully protected, fully compliant, and secure.

    There is definitely a huge impact on the organization that we observed. There was an 80% efficiency increase with the deployment of this antivirus solution, which causes fewer incidents to be created whenever any alert is generated in real time. We saved a lot of time in terms of mitigating or identifying threats and quickly taking action on securing the AWS account from malware infection spread. It saves a lot of time and has improved the overall efficiency and effectiveness of the account and storage devices.

    What needs improvement?

    I would definitely say that if the solution gets updated on a day-to-day basis so that the cloud signature gets updated for all AWS account holders during the scanning, and if the deployment of updates happens every day, it would be helpful. Additionally, if AI and machine learning can be used in detecting and identifying algorithms to quickly identify malicious files across the storage locations and storage paths, it would really help enhance the solution.

    There are no major issues, but if the company could work on deployment features as well as cost-effectiveness and some specific features that require licensing needs, it would be really helpful.

    For how long have I used the solution?

    I have been using Antivirus for Amazon S3 for more than three years.

    What do I think about the stability of the solution?

    It is very stable. In terms of performance, overall functionality, and features, it is very stable in terms of deployment and taking updates.

    What do I think about the scalability of the solution?

    It is really scalable and good in terms of being scalable as per our requirement, as per the storage capability and storage requirement. It can be easily extended if we move from low storage to high storage while ensuring the S3 bucket capabilities and functionality. It can be easily scalable whenever required.

    How are customer service and support?

    The support was very fantastic. They helped a lot in terms of the integration and deployment of this product's antivirus solutions.

    Which solution did I use previously and why did I switch?

    I evaluated SentinelOne Singularity Endpoint  because we were getting a lot of false positives. It was not generating many true positive alerts. We were receiving a lot of false positive alerts on business-related files that were identified as a suspicious category. I moved to Antivirus for Amazon S3 because of these issues.

    How was the initial setup?

    The best feature is definitely the deployment. The deployment takes less than 10 minutes.

    What about the implementation team?

    There is a lot of improvement that I see with the deployment of this antivirus solution. Fewer employees were needed because this antivirus solution not only takes actions automatically but also remediates threats quickly. We saved a lot of money because it is a cloud-based solution, so we pay for what we use. A lot of time was saved, and there is good effort in terms of investigation and identification of threats.

    What was our ROI?

    There is definitely a huge impact on the organization that we observed. There was an 80% efficiency increase with the deployment of this antivirus solution, which causes fewer incidents to be created whenever any alert is generated in real time.

    What's my experience with pricing, setup cost, and licensing?

    The deployment and the pricing are very good. I take the services for a longer time period, so the vendor worked in an easy and cooperative way in deployment.

    What other advice do I have?

    I would provide a rating of nine because this antivirus solution is working in a very positive way in protecting the entire organization and confidential data and storage across the S3 buckets. It helps in securing the devices, securing the files, and securing the confidential data.

    I think others should definitely go for Antivirus for Amazon S3. The reason is that it is not just about protecting from malicious files, but it takes action immediately by quarantining the file and deleting the file whenever needed. I can perform automated actions, automated alert investigation, and quickly block threats from the organization. It definitely works in a real-time scenario. Since it is integrated with the cloud, it is really easy to get support from the cloud storage. Additionally, the cloud signature gets updated every day, which is really helpful. I would rate this solution a nine out of ten.

    Automated file scanning has improved security and now lets us focus more on core development work

    Reviewed on Apr 18, 2026
    Review from a verified AWS customer

    What is our primary use case?

    Antivirus for Amazon S3  is typically used for scanning files uploaded to S3  buckets for malware before they are consumed by downstream services. This is especially critical when handling user-generated content or third-party uploads.

    What is most valuable?

    One of the best features of Antivirus for Amazon S3  is automatic malware scanning on upload without needing to manage infrastructure. AWS  native solutions such as GuardDuty Malware Protection provide fully managed agent-less scanning.

    A key aspect of Antivirus for Amazon S3 that is worth mentioning is the ability to receive notifications and alerts when potential threats are detected, which allows my team to take swift action and ensure the security of our application.

    Antivirus for Amazon S3 has improved our overall security posture, especially for compliance-heavy applications. My team became more confident handling external file uploads. We reduced custom infrastructure costs by around 30% since we did not need EC2-based scanning pipelines. Additionally, development times dropped by about 20% due to the managed service.

    I have seen a significant improvement in my team's productivity since we implemented Antivirus for Amazon S3. The 20% reduction in development time has allowed us to focus on higher-priority tasks. With the managed service handling the scanning, our developers can now allocate more time to feature development and less time to infrastructure management.

    What needs improvement?

    One limitation I have identified is that advanced customizations can be tricky with fully managed solutions for Antivirus for Amazon S3. Sometimes we need more control over scanning logic or workflows.

    For needed improvements, I would say documentation is good, but troubleshooting scan failures or false positives can still take time with Antivirus for Amazon S3. Better debugging tools would help.

    One area I would like to see improved for Antivirus for Amazon S3 is the automation of certain security protocols, such as automatic updates and patch management to further enhance our security posture. I believe this would help us streamline our operations and reduce the risk of human error.

    For how long have I used the solution?

    I have been using Antivirus for Amazon S3 for about a year now, primarily in projects where users upload files such as documents or images. It became important when we started dealing with untrusted file uploads.

    What do I think about the stability of the solution?

    Antivirus for Amazon S3 is very stable, especially AWS-managed solutions. We have not experienced any major downtime or failures in our scanning workflows.

    What do I think about the scalability of the solution?

    Scalability for Antivirus for Amazon S3 is excellent. It can handle high volumes of uploads without performance degradation since it builds on S3 's event-driven architecture.

    How are customer service and support?

    Customer support for Antivirus for Amazon S3, specifically AWS  native solutions, is solid if you have an enterprise plan. Community and documentation also cover most common issues.

    Which solution did I use previously and why did I switch?

    Earlier, we used a custom EC2-based antivirus pipeline, but it required maintenance and scaling efforts, which is why we switched to a managed solution for simplicity.

    How was the initial setup?
