Stairwell, Inc. provides a private threat intelligence and malware analysis platform designed to help defenders answer hard questions quickly and with evidence. It collects executable and executable-like files from customer environments, stores them in a private cloud vault, and continuously analyzes and reanalyzes those artifacts as threat intelligence evolves.
The platform is built for organizations that need more than point-in-time alerts. By combining file preservation, retrospective search, IOC correlation, and variant-aware analysis, Stairwell, Inc. helps teams determine whether a threat has touched their environment, understand related activity, and move from alert triage to scoped investigation with less manual work.
Offerings, Capabilities, and Integrations
Stairwell, Inc. centers its offering on continuous file visibility, private artifact retention, and cloud-based analysis that complements existing endpoint and security operations tooling. Its capabilities span malware analysis, enterprise-scale YARA hunting, threat report operationalization, variant discovery, and investigation workflows that connect files, infrastructure, hosts, and timelines.
The platform is designed to fit into established security programs rather than replace them. Stairwell, Inc. supports integrations with EDR, SIEM, and SOAR environments such as CrowdStrike Falcon, SentinelOne, Splunk, Palo Alto Cortex, Tines, Slack, and Google Security Operations, and it also exposes APIs and webhooks for custom workflow automation.
Products and Services
- Stairwell Core: Privacy-first malware analysis and file preservation offering for teams that want continuous reassessment, YARA scanning, variant discovery, and EDR-connected suspicious file analysis without using public malware services.
- Stairwell Enterprise: Enterprise-scale deployment of the Stairwell platform for collecting, preserving, and continuously reanalyzing executable and executable-like files across the environment, with deeper hunting and investigative coverage.
- AI Triage: Automated file analysis capability that evaluates uploaded files for maliciousness, correlates prevalence and variant signals, applies YARA and threat intelligence context, and produces human-readable assessments.
- Variant Discovery: Malware family analysis capability that expands from a single sample to related variants across private and global data sets, helping analysts uncover repacked, modified, and otherwise hidden malware.
- Run-to-Ground: Investigation workflow that turns an alert, IOC, or file into a campaign-level view by connecting related files, endpoints, timelines, and infrastructure to establish scope and blast radius.
- Threat Reports: Threat intelligence workflow that maps indicators from published or custom threat reports to historical and current file inventory so teams can quickly confirm exposure and prioritize response.
- Stairwell Forwarder: Lightweight file sighting and collection component that watches for new executable and script files, deduplicates uploads, and sends artifacts for analysis with minimal endpoint overhead.
- Stairwell App for Splunk: Splunk integration that enriches hashes, hostnames, and IP addresses in Splunk data with Stairwell intelligence to support faster investigation and triage.
Target Customers
Stairwell, Inc. serves security operations teams, incident responders, threat hunters, and threat intelligence practitioners that need durable visibility into files across time. Its platform is suited to organizations that want to investigate suspicious files privately, validate exposure to newly published IOCs, and reduce the manual pivoting that slows alert handling and incident scoping.
The company addresses both lean security teams and larger enterprises with complex, distributed environments. It is relevant for mid-market and Fortune 500 organizations, as well as CISOs, IT and endpoint teams, and compliance or audit stakeholders that need defensible answers about what files were present, where they appeared, and whether remediation is complete.
Cloud Integrations and Marketplace
- Google Cloud Marketplace: Stairwell, Inc. offers its platform through Google Cloud Marketplace, giving customers a cloud marketplace procurement path aligned with Google Cloud environments.
- Google Security Operations: Stairwell, Inc. integrates with Google Security Operations to enrich IOC-driven cases and workflows with malware context, variant relationships, and analysis results.
