Antivirus for Cloud Storage

Cloud Storage Security for AWS, Azure, and GCP

Protect data in-tenant at the storage layer ( Amazon S3, Azure Blob Storage, and Google Cloud Storage ). Run in-tenant malware scanning across buckets and accounts. Use multi-engine malware detection to identify malicious files before they spread. Scan new and existing objects automatically. Keep evidence centralized for audit and incident response. Export audit-ready reports and integrate results with native AWS services like Amazon SNS, CloudWatch, AWS Security Hub, and AWS Transfer Family.

Virus & Malware Scanning Made Easy

Enhance your cloud storage security posture with fast, reliable malware protection for Amazon S3 and other object storage services.

Quick & Easy Setup

Protect Users in 15 Minutes or Less

You can deploy without agents and without complex integrations. Most teams begin scanning both new uploads and existing Amazon S3 objects in minutes.

Everything runs in your environment (your AWS account, your Azure subscription, your GCP project), so sensitive data never leaves your cloud. This supports both security requirements and compliance expectations around data residency and data handling.

Ensure User-Generated Content is Safe

Integrate Scanning without Disruption

If your business accepts files from customers, partners, contractors, or internal users, you need to verify that content before it lands in production storage.

Utilize automated S3 malware scanning, Azure Blob malware scanning, and Google Cloud Storage malware scanning at scale:

Scan every upload in near real time.
Catch dormant or embedded threats, not just obvious signatures.
Maintain performance so users are not blocked or delayed.

The platform supports nearly every common file type stored in object storage and applies the same policies across AWS, Azure, and GCP. That gives you always-on protection and consistent compliance coverage.

Seamless Integration with AWS

Extend AWS Solutions

Extend and enrich your existing AWS security controls

We plug into the AWS services your security and operations teams already use:

Alerts & notifications: Send scan findings through Amazon SNS and route them to Slack, email, ticketing, or AWS Security Hub for centralized triage.
Audit logging: Stream logs to Amazon CloudWatch for visibility, troubleshooting, and long-term retention.
Secure ingestion: Pair with AWS Transfer Family to inspect incoming files at the point of entry so malware is blocked before it spreads across buckets or accounts.

This gives you malware protection for Amazon S3 that aligns with AWS-native telemetry instead of adding another disconnected console.

Proof of Protection at the Push of a Button

You can:

Manage malware protection policies from a central console.
Tag, quarantine, or remove infected objects automatically, based on your rules.
Generate audit-ready reports at the bucket level or account level to show customers, partners, internal stakeholders, and auditors

You get documentation that supports investigations, incident response, due diligence, and compliance without hand-built spreadsheets.

Security Features

01

Forensic Analysis
and Visibility

See exactly where threats originate.

You get object-level scan results by bucket and by account. That means you can trace when a malicious file entered storage, which users or systems touched it, and where similar payloads are clustering. This shortens investigation time and limits blast radius in the event of ransomware or data exfiltration.

02

Detonation
Capabilities

Isolate and analyze suspicious files safely.

Send suspect objects to a secure cloud sandbox for both static and dynamic analysis. You can observe behavior, extract indicators, and understand intent — before those files are allowed deeper into your environment.

03

Automatic
Protection

Cover every bucket, not just the obvious ones.

Use an auto-protect tag so event-based scanning starts the moment a new bucket is created. Schedule batch jobs to scan existing data at scale, including archives and long-lived content that may not be touched often but still poses risk.

This eliminates blind spots where malware sits undetected in storage for months.

04

Multi-Cloud
Coverage

Apply one policy everywhere.

Scan files in:

Amazon S3
Azure Blob Storage
Google Cloud Storage

Use consistent quarantine actions, consistent reporting, and consistent evidence across clouds. This supports shared services teams and reduces the operational overhead of running separate malware protection tools for each cloud provider.

Architecture

Here’s how it works for Amazon S3.

An S3 event (new object upload, change, etc.) triggers an in-tenant malware scan. The object is evaluated by multiple malware detection engines. Based on your policy, the platform can tag the file, quarantine it, or block access. Findings stream automatically to Amazon SNS for alerting, Amazon CloudWatch for logs, and AWS Security Hub for correlation. Teams can export bucket-level and account-level reports to document remediation, prove Amazon S3 malware protection, and satisfy auditors. You can also run scheduled batch jobs across existing buckets to cover historical data, archives, and cold storage. Optional sandbox detonation provides deeper analysis for suspicious files.

This architecture supports single-account and multi-account AWS topologies, multiple AWS regions, and scale-out as you add storage. The same scanning model and reporting model are available for Azure Blob Storage and Google Cloud Storage, so you can standardize across clouds.

Customers Trust Cloud Storage Security

Exactly what we needed... We were considering one of the higher cost data security platforms, but found that most of them don't directly scan the files in S3 (...).

- Dan Iorg

We had already evaluated Kaspersky, TrendMicro, and Sophos and were about to give up. Super happy with the solution.

- Anonymous

Quick and easy to setup... It took only few hours to read the documentation and setup and it was just working so no need to invest more time in testing alternative solutions.

- Gabriel T.

This solution completely met our expectations and requirements.

- Ivan

If you need affordable object storage scanning at scale, I am confident you will not find a better offering on the market nor a better team to help you get up and running.
