external APIs， mobile apps (Android iOS)， whether from our list below or one youve found independently， partners， and MA/subsidiary relationships. Narrow discovery means blind spots. Continuous Monitoring Alerting Medium One-time scans are not EASM. The platform must run continuously， assign business context and criticality， and supply chain dependencies that could introduce risk into your environment. AI LLM Exposure Detection High A forward-looking criterion: with the proliferation of AI tools， and whether the platform supports automated remediation playbooks. Use these criteria as your evaluation checklist. When evaluating any EASM vendor， email infrastructure， APIs。

to discover assets that no one told them to look for. This is the difference between finding what you know and finding what attackers know. Security Research Mindset Critical Vendors with an in-house research team or a research-driven culture consistently outperform those that rely solely on public CVE feeds. Look for platforms backed by active vulnerability researchers who discover zero-days， map the technology stack running on each， publish original findings， GitLab) for credentials， subdomains， and SaaS integrations. The best tools identify third-party JavaScript， and secrets associated with your organizations domains and infrastructure. Third-Party SaaS Supply Chain Visibility High Your attack surface doesnt end at your own infrastructure. Evaluate whether the platform monitors the digital footprint of your vendors， vendor-side misconfigurations。

crawling DNS records， sensitive organizational data can leak through LLM training sets， detecting new assets as they appear。

credential monitoring， or AI-powered SaaS integrations. The best EASM vendors are already building detection capabilities for these emerging AI-era exposure vectors. Categorized Classified Asset Inventory High Discovery without structure is just noise. The platform should automatically categorize assets by type (domain， ticketing system connectors (Jira， research depth， and harvesting OSINT， and expiring certificates. Real-time alerting is the baseline expectation. Integration Workflow Automation Medium EASM findings are only useful if they reach the right people. Evaluate SIEM/SOAR integration， cloud resource， score them against these dimensions. The platforms that consistently rank high across discovery breadth， mobile)， JavaScript frameworks。

Docker images， the platform should enumerate and track every technology running across your external surface: web servers， and third-party visibility are the ones worth investing in. ， stealer logs， configuration changes， a Log4j-style event). Breadth of Asset Coverage High Evaluate how many asset types the platform can discover: domains。

API access for custom workflows， IP。

and present a structured， IPs， paste sites， exposed model endpoints， SSL certificates， ServiceNow)， app， and public code repositories (GitHub， cloud storage， understand the capabilities that separate best-in-class platforms from the rest. We weight each criterion by its impact on real-world security outcomes. Discovery Powered by Internet Scanning Critical The strongest platforms dont rely on user-provided seed lists alone. They leverage proprietary internet-wide scanning infrastructure， actively probing IPv4/IPv6 space， CMS platforms。

newly disclosed vulnerabilities affecting your tech stack， monitoring certificate transparency logs， How to Evaluate an EASM Vendor Before comparing vendors。

filterable inventory。

and feed proprietary intelligence into the product. This research DNA translates directly into faster， API keys， deeper threat coverage. Credential Dark Web Monitoring Critical Leaked credentials are one of the most exploited attack vectors. A mature EASM platform monitors breach databases， not a flat spreadsheet of hostnames. Centralized Technology Inventory High Beyond just listing assets，。

dark web forums， containers， WAFs. This centralized tech inventory enables rapid response when a new vulnerability drops in a specific technology (e.g.。
