Requires Expertise

You can use Stairwell to collect and permanently store every executable file that touches your enterprise environment, then continuously analyze them for threats. It detects malware that other tools miss by examining files directly rather than relying on prior alerts. When a new threat is identified, it automatically re-scans years of file history, maps how far the malware spread across hosts, and generates a full investigation report with remediation steps tied to your existing security tools.
