The Assetnote Continuous Security Platform continuously maps internet‑facing assets using advanced, largely agentless reconnaissance techniques, keeping an always‑current asset inventory. It performs high‑signal security analysis and real‑time exposure monitoring—often scanning hourly—to detect real, exploitable exposures while filtering out false positives, and integrates attack‑surface and exposure data into SIEMs and MSSP workflows.
