External Attack Surface Management
See your entire attack surface. Act on what matters.
External Attack Surface Management (EASM) is the continuous discovery, monitoring, and risk assessment of an organization's internet-facing assets. Deepinfo EASM finds every domain, subdomain, IP address, certificate, and exposed service tied to your perimeter (including the ones you don't know you own), and scores each by real-world exploitation signal.
Deepinfo's External Attack Surface Management module discovers every internet-facing asset associated with your organization, monitors them continuously across seven data layers, and surfaces vulnerabilities enriched with real-world exploitation signal. Built on internet-scale data we own.
You can't secure what you don't know you own.
Every modern organization has more internet-facing assets than its security team can name. Subsidiaries register domains. Partners spin up infrastructure. Acquisitions bring legacy systems. Marketing teams launch campaigns from new subdomains.
Attackers find what defenders lose track of. Most successful external attacks start at an asset the security team didn't know was theirs.
EASM closes that gap. Continuous discovery, continuous monitoring, continuous risk scoring across every asset associated with your organization, including the ones you didn't know about.
Five capabilities, working as one system.
Each capability below is a sub-feature with its own page. They're built to work together: discovery feeds scanning, scanning feeds risk detection, risk detection feeds remediation, all of it feeds risk scoring. Click any card to go deeper.
Smart Asset Discovery
Find every domain, subdomain, and IP address associated with your organization. Includes the ones your inventory missed: subsidiary infrastructure, shadow IT, post-acquisition assets, partner-hosted environments.
Learn more FEATURE 02Continuous Scanning
Every monitored asset is scanned continuously across seven data layers: Whois, IP-Whois, DNS, SSL, port scan, HTTP, and web content. Drift detection on every change.
Learn more FEATURE 03Comprehensive Risk Detection
Misconfigurations, weak SSL/TLS settings, expired certificates, exposed services, and known vulnerabilities surfaced in one feed. Each finding is severity-tagged and mapped to compliance frameworks.
Learn more FEATURE 04Remediation with Actionable Insights
Each finding includes evidence, reproduction steps, and a clear remediation path. A nine-state issue lifecycle covers everything from newly detected through verified resolved.
Learn more FEATURE 05Complete Risk Scoring
Every asset gets a security score. Every domain gets a domain-level score. Every vulnerability is enriched with EPSS exploit-prediction and CISA KEV "actively exploited" flags so prioritization tracks real-world exploitation, not just theoretical severity.
Learn moreEvery CVE, enriched with real-world exploitation signal.
Most exposure platforms surface vulnerabilities with CVSS scores. CVSS tells you how severe a vulnerability could be in theory. It doesn't tell you whether attackers are actually exploiting it.
Deepinfo enriches every detected CVE with EPSS, the Exploit Prediction Scoring System, which models the likelihood that a vulnerability will be exploited in the next 30 days based on real-world data. We also flag every CVE in CISA's Known Exploited Vulnerabilities catalog, so you know which ones are being exploited right now.
The result: instead of a queue of "critical" findings sorted by severity that may or may not matter, your team sees what's actually being exploited, on assets that are actually exposed, with evidence and a clear path to remediate.
CVE + CVSS
Severity in theory. A queue sorted by what could be bad, without knowing which ones attackers are actually using.
CVE + CVSS + EPSS + CISA KEV
Severity, exploitability, and active-exploitation signal. The same finding, prioritized against what's actually being exploited in the wild.
Mapped to the frameworks your auditors care about.
Every issue Deepinfo surfaces is classified against the frameworks compliance and audit teams report against. When the audit asks which findings map to PCI DSS 4.0 Requirement 6.4, the answer is one filter, not a spreadsheet exercise.
What your team gets out of it.
Reports for executives and operators.
Executive summary. Weekly progress. Asset detail, vulnerability detail and overview, issue detail and overview. Generated on a schedule or on demand. Exportable.
Alerts that route to where your team works.
Fifteen event types. Routed to email, Slack, your SIEM, or your ticketing system. Frequency configurable per channel: instant, hourly, daily, weekly, monthly. No noise; no missed signal.
An API for everything else.
Every finding is available via API. SIEM integrations, ticketing automation, custom dashboards. The platform doesn't trap your data. See the API reference.
“We thought we had a complete asset inventory. Deepinfo's discovery added 30% more assets within the first month, mostly subsidiary infrastructure and shadow IT nobody had documented. The continuous scanning catches new exposures before our pen-testers do.”
