ReversingLabs Cloud Sandbox

ReversingLabs Cloud Sandbox analyzes submitted files by running them in isolated environments and observing their behavior, complementing static analysis. It supports automatic analysis and live interactive sessions where an analyst can engage with a sample. Analysis is available for Windows, macOS, Linux, and Android; Android supports file submissions, not URL analysis. Reports include network and behavioral indicators, process activity, registry and file changes, and downloadable artifacts. Files can be submitted through the Dynamic Analysis Submission API. A feature preview limits submissions to five samples per day; full access costs extra through ReversingLabs Sales Support. Individual samples can be up to 400 MB, and artifacts remain available for download for one year. For private samples, other customers can see results but not sample contents, dropped files, PCAP files, or memory string dumps. VPN routing is used when samples may connect to the internet. The service is described for security operations teams handling incident response and threat hunting. Pricing lists a free plan, paid access from $500/mo, and a 14-day trial.

This sandbox suits security operations teams conducting incident response or threat hunting. It may be useful for analysts who need file behavior reports or interactive sample analysis.

ReversingLabs Cloud Sandbox is a cloud service for executing suspicious files in isolated environments and examining what they do. It best suits security operations teams conducting incident response or threat hunting. Its behavioral reports, interactive sessions, and submission API make it a focused analysis tool, though the five-sample daily preview and paid full access matter for teams with regular workloads.

Overview

Dynamic analysis complements static analysis by observing a file as it runs. Cloud Sandbox supports automatic analysis as well as live sessions where analysts can interact with a sample. Completed runs produce reports covering network and behavioral indicators, process activity, and registry and file changes, with artifacts available to download.

Private samples have a meaningful privacy boundary: other ReversingLabs customers may access analysis results, but not sample contents, dropped files, PCAP files, or memory string dumps. When a sample may reach the internet, VPN routing masks the origin of its network requests and protects the analysis infrastructure.

Key features

• Multiple analysis modes: Automatic runs suit routine triage; interactive analysis gives analysts room to inspect a sample during a live session.
• Broad system coverage: Analysis supports Windows, macOS, Linux, and Android. Android submissions are limited to files, not URLs.
• Reports and artifacts: Reports include network and behavioral indicators, process activity, and registry and file changes. Downloadable artifacts remain available for one year, the standard retention period.
• Submission API: The Dynamic Analysis Submission API accepts files directly, which suits workflows that need to submit samples programmatically.
• Analysis limits: Individual samples can be up to 400 MB. Feature-preview submissions are capped at five samples per day; full access costs extra.

ReversingLabs also describes integrations across its Malware Analysis and Threat Hunting portfolio with TIP, SIEM, and SOAR platforms, sandboxes, storage systems, email gateways, and web proxies, with APIs and SDKs for customization. For Cloud Sandbox to be available in Spectra Analyze, the appliance must connect to Spectra Intelligence.

Pricing

The pricing model is freemium: there is a free plan, paid access starts at $500/mo, and a 14-day trial is offered. The Cloud Sandbox plan has no listed price; full access is available at additional cost, while the feature preview allows five samples per day. That cap can work for occasional evaluation, but is restrictive for teams processing a steady stream of files. The 400 MB per-sample ceiling also sets a practical boundary regardless of plan.

ReversingLabs includes standard 9x5 support with each Malware Analysis and Threat Hunting product, with a premium 24x7 option available. Teams that require round-the-clock assistance should account for that separate support option.

Platforms

The service is cloud-deployed and supports analysis on Windows, macOS, Linux, and Android, alongside API access and URL analysis. Android support is for file submissions rather than URL analysis. ReversingLabs describes hybrid deployment options for its offering.

Who it's for

Cloud Sandbox is a strong fit for security operations teams that need to inspect file behavior during incident response or threat hunting, especially when they value interactive analysis, downloadable evidence, and API submission. It is less suited to high-volume use on the preview tier, or to workflows that depend on Android URL analysis.

Pros and cons

• Pro: Automatic and interactive modes support both repeatable triage and closer examination of a live sample.
• Pro: Reports combine network, process, registry, and file-change indicators, while downloadable artifacts are retained for a year.
• Pro: Private-sample protections restrict other customers from accessing sample contents and sensitive analysis artifacts.
• Con: The preview is limited to five submissions per day, and full access has an additional cost, making sustained use dependent on a paid arrangement.
• Con: Android submissions do not support URL analysis, which narrows that platform's coverage.

Verdict

Choose ReversingLabs Cloud Sandbox if your security operations team needs isolated file execution with interactive analysis, detailed behavioral evidence, and API-based submission. Its main advantage is the combination of live investigation and downloadable reports; its main drawback is the preview's five-sample daily cap and the extra cost of full access. Teams needing regular volume should weigh that cost against their workload before committing.
