Choosing an External Attack Surface Management Tool | UpGuard

This report defines Attack Surface Management (ASM), contrasts it with vulnerability management, outlines its importance and implementation challenges, and identifies key capabilities to seek (e.g., continuous discovery, external scanning, and vendor risk workflows). It then compares 10 leading ASM-related platforms for 2026—such as UpGuard, Bitsight, SecurityScorecard, ProcessUnity, RiskRecon, and Recorded Future—summarizing their core features, strengths, limitations, and target customers. The document concludes with real-world case studies that illustrate how organizations use ASM, particularly UpGuard, to improve external asset discovery, reduce attack surfaces, and enable continuous monitoring across complex, distributed environments.
