Stairwell Gather is a data-agnostic threat intelligence aggregation platform that continuously collects, unifies, and analyzes signals from multiple sources including enterprise files, malware feeds, DNS resolutions, EDR alerts, and published threat reports. **Private Vault:** Enterprise files are stored in a private vault that is never shared with third parties, addressing concerns around public file upload exposure. Stairwell builds file history and reputation over time to answer what a file is, where it came from, and when it first appeared. **Malware Corpus:** Stairwell continuously ingests newly identified malware into an expanding Malware Corpus, which is then used to reanalyze files in the Private Vault to uncover new variants and identify previously unknown threats. **Threat Report Operationalization:** Stairwell researchers and AI agents extract IOCs from published threat reports and automatically run them against enterprise files to identify exposure, reducing manual analyst effort. **IP & Domain Reputation:** The platform ingests over four billion active DNS resolutions daily, tracking IPs and domains as adversaries rotate infrastructure to provide current reputation context for malware files. **EDR Alert Consumption:** Gather integrates with EDR platforms, automatically collecting suspicious files flagged by alerts and running deeper analysis to provide SOC analysts with an independent verdict. **YARA Rule Support:** YARA rules are treated as first-class intelligence. Users can access a library of third-party and Stairwell-authored rules, and upload custom rules into private or shared vaults for hunting without data exposure. The platform is built for scale, with web-scale indexing and AI-assisted reasoning applied across all collected artifacts.
