MetaDefender Storage Security is a powerful tool that adds a scalable file-security layer to AWS S3 Buckets. It scans user-uploaded files for malware, detects suspicious files, removes potentially malicious content, and automatically redacts or reports sensitive data. It integrates easily with cloud and on-premises storage services and provides IT security professionals with automated audit reports for quick remediation.
Before newly uploaded files enter a protected S3 bucket, real-time scanning triggers an S3 event to scan the file. During the scan, files are inspected and analyzed for vulnerabilities, zero-day threats, and compliance violations. Additionally, you can schedule weekly or monthly on-demand file scans using the polling process.
Highlights
- Flexible file scanning: Real-time scanning instantly scans files prior to being uploaded to S3 buckets. Scans can also be scheduled or run on-demand.
- Detect malware: Leverage Multiscanning with 30+ anti-malware engines to detect nearly 100% of known malware threats.
- Prevent zero-day attacks: Disarm active embedded threats and reconstruct a sanitized version of files to prevent zero-day threats and advanced evasive malware using Deep Context Disarm and Reconstruction (Deep CDR).

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Consistent Background Scanning with Easy to Understand Results
Reviewed on Jan 16, 2026
Review provided by G2
What do you like best about the product?
File scanning runs consistently in the background and we have not seen noticeable slowdowns in applications or file services. The scan results are easy for non security teams to understand, which helps reduce escalations to IT. Integration was also straightforward, allowing us to add file inspection into existing systems without introducing new tools for staff to manage.
What do you dislike about the product?
The main effort is during rollout. Policies need careful adjustment so business files are not blocked unnecessarily. Once tuned, ongoing maintenance is minimal.
What problems is the product solving and how is that benefiting you?
It reduces operational risk caused by infected or suspicious files entering the environment. This leads to fewer disruptions, fewer support tickets, and a more stable IT environment overall.

Fast, Clear Scanning with File Sanitization That Keeps Workflows Moving
Reviewed on Jan 15, 2026
Review provided by G2
What do you like best about the product?
MetaDefender protects against file based threats without forcing changes to existing security architecture. Scanning is fast and consistent, and the results are clear enough to automate actions. The option to sanitize files instead of blocking them helps maintain normal business workflows.
What do you dislike about the product?
Policy tuning requires attention, especially when dealing with archives or mixed file types. Early testing is important to prevent overly strict rules from interrupting normal traffic.
What problems is the product solving and how is that benefiting you?
It reduces exposure to file based threats coming from external users, vendors, and integrations. This lowers incident frequency, improves confidence in inbound content, and strengthens overall security posture without adding operational friction.

Reliable, Workflow Friendly Scanning with Easy to Use API
Reviewed on Jan 15, 2026
Review provided by G2
What do you like best about the product?
MetaDefender fits well into automated workflows and runs reliably without manual intervention. The API responses are easy to consume in scripts and jobs, and scanning performance stays consistent even when tasks run in parallel.
What do you dislike about the product?
Some upfront policy tuning is needed to prevent automated jobs from failing on edge case file types.
What problems is the product solving and how is that benefiting you?
It adds automated file security checks without breaking hands-off workflows. This reduces risk from untrusted inputs while keeping automation reliable, predictable, and easy to maintain at scale.

MetaDefender Simplifies Consistent, Scalable File Scanning Across Platforms
Reviewed on Jan 14, 2026
Review provided by G2
What do you like best about the product?
MetaDefender makes it easier to enforce consistent file scanning across shared platforms. It scales well as usage grows and avoids each application having to build its own file security logic. Policies are flexible enough to support different risk levels while keeping a common security baseline.
What do you dislike about the product?
Some upfront planning and tuning are needed to align policies with multiple application teams.
What problems is the product solving and how is that benefiting you?
It centralizes file security at the platform layer. This reduces exposure from third party content and helps maintain consistent protection as new services are added.

Fast, CI/CD Friendly Scanning and File Sanitization via MetaDefender API
Reviewed on Jan 14, 2026
Review provided by G2
What do you like best about the product?
MetaDefender integrates cleanly into automated pipelines using its API. File scans are fast and consistent, and the results are easy to consume in CI/CD workflows. The ability to sanitize files instead of only blocking them helps keep builds and deployments moving without compromising security.
What do you dislike about the product?
Policy tuning is needed early on so legitimate build artifacts are not flagged or blocked unnecessarily.
What problems is the product solving and how is that benefiting you?
It shifts file security earlier in the delivery process. This reduces production risk while allowing teams to maintain steady release velocity.
