Anomali Attack Surface Management
Mid-market and enterprise security teams drowning in unknown external assets will find immediate value in Anomali Attack Surface Management's discovery engine, which maps your entire digital footprint across domains, cloud, SaaS, and hardware without requiring agent deployment. The platform's continuous monitoring paired with risk-based prioritization means you stop chasing every vulnerability and focus on what actually exposes you to attack; its integration with Anomali Match Cloud threat intelligence directly connects your surface to known adversary tactics. This tool assumes you have the resources to act on what it finds, so lean security ops teams relying on a small contractor to handle external risk should look elsewhere.
Security teams running lean reconnaissance workflows will get the most from as3nt; it's a fast, no-friction subdomain enumerator that doesn't require API keys or cloud dependencies, making it ideal for quick discovery during initial scoping or red team engagements. The 12 GitHub stars underscore it's a specialized tool favored by practitioners who've already standardized on heavier EASM platforms and need a lightweight complement. Skip as3nt if you're looking for continuous monitoring, DNS record analysis, or integration with your ticketing system; this is pure enumeration, nothing more.
