What is EASM?

Your perimeter is everywhere. Monitor it that way.

External Attack Surface Management (EASM) is the continuous practice of discovering, classifying, and monitoring every internet-facing asset your organization owns — known or unknown.

This tool combines automated asset discovery, lookalike domain detection, vulnerability checks, and defacement monitoring into a single, always-on layer — so your security team sees what attackers see.

Use cases

Built for every team that owns risk

Digital Risk Analyzer adapts to your context — whether you're a security team, a compliance officer, or running acquisition due diligence.

Know your surface before attackers do

Security teams managing multiple domains often don't have a complete picture of what's exposed. The tool gives you a continuously updated inventory of every internet-facing asset, ranked by risk — so your team works on what matters most.

  • Discover subdomains and IPs you didn't know existed
  • Get alerted the moment a new asset appears or a score drops
  • Track CVEs across your exposed services without manual scanning
  • Detect defacement and unauthorized page changes in real time

Audit-ready from day one

Compliance teams need documented evidence of security controls and risk assessments. Digital Risk Analyzer generates branded, timestamped PDF reports on your external attack surface — aligned with DORA, NIS2, and ISO 27001 requirements.

  • Generate reports at scheduled frequencies or on demand
  • Demonstrate continuous monitoring — not just point-in-time snapshots
  • Track score history for trend analysis across audit periods
  • Identify and document areas of non-compliance before auditors do

Find assets you didn't know existed

Shadow IT is one of the biggest sources of unmanaged risk. Forgotten staging servers, test environments left open, abandoned subdomains — Digital Risk Analyzer surfaces all of it without requiring any internal network access.

  • Automatic subdomain enumeration from a single root domain
  • IP and host discovery without agents or network probes
  • Flag open services and exposed ports on unmanaged assets
  • Ongoing monitoring catches new shadow assets as they appear

Assess acquisition risk before it's too late

M&A teams need rapid, credible security assessments of target organizations. Digital Risk Analyzer scans any domain — not just your own — and returns a full external risk profile within minutes, not weeks.

  • Run security due diligence on acquisition targets from day one
  • Identify hidden liabilities: expired certs, open ports, outdated software
  • Compare target scores against industry benchmarks
  • Generate shareable PDF reports for deal teams and advisors
