What is external attack surface management (EASM)?
The external attack surface encompasses all systems, services, and entry points accessible to an adversary from the Internet. EASM refers to continuous discovery, inventory, and analysis of an organization’s external digital assets—all from an attacker’s perspective.
EASM makes it possible to identify all internet-facing assets such as domains, subdomains, IP addresses, web applications, APIs, and other public services, including previously unmapped or forgotten. The focus extends beyond vulnerabilities to overall asset exposure (availability, configurations, and exploitation risks).
This approach ensures full visibility into the external perimeter, uncovers shadow IT, and enables prioritization of risks based on their real-world significance for adversaries.
What are the benefits of continuous external attack surface management?
Complete up-to-date visibility of external assets, including shadow IT
Reduced time to detect for vulnerabilities
Real-time risk awareness
Streamlined remediation
Lowered probability of a successful external breach
How often should vulnerability scans run?
With EASM, scheduling is unnecessary—scanning is continuous. This eliminates the blind spots that typically occur between one-off pentests.
What makes EASM different from standard penetration testing?
A traditional pentest is a point-in-time assessment designed to identify attack scenarios and answer the question, “How exactly can we be breached?” Its findings are only valid at the time the test is conducted.
EASM serves a different purpose. It provides continuous external perimeter monitoring, showing which assets are internet-accessible, which are potentially vulnerable, and how the attack surface evolves over time.
For example, BI.ZONE EASM continuously monitors external assets, detects new vulnerabilities as they emerge, and tracks their remediation in real time.
How does BI.ZONE EASM differ from vulnerability scanners?
Vulnerability scanners identify potential issues but often lack the context needed for effective prioritization. BI.ZONE EASM goes further by combining automated scanning with expert validation, full vulnerability lifecycle management, and remediation tracking.
What assets does BI.ZONE EASM monitor?
The platform analyzes your entire external perimeter, including domains, IP addresses, web applications, open ports, and network services. Assets are identified and tracked dynamically, ensuring that new or previously unknown resources are immediately accounted for.
How does BI.ZONE EASM help discover shadow IT assets?
The platform automatically discovers unmapped assets on your external perimeter, such as forgotten domains, test environments, open ports, and other resources missing from internal registries.
By leveraging OSINT methodologies, BI.ZONE EASM identifies assets exactly as adversaries do. This allows you to promptly locate shadow IT assets, remediate associated vulnerabilities, and reduce the risk of breaches through unmanaged entry points.
How does BI.ZONE EASM help manage vulnerabilities?
The platform enables you to:
inventory external assets, such as domains, IP addresses, web applications, and services
detect external perimeter vulnerabilities
prioritize risks based on their CVSS and EPSS scores and inputs from BI.ZONE Threat Intelligence
get remediation guidance
track remediation progress
uncover shadow IT (previously unknown domains and services)
All data is centralized in a single interface, featuring detailed vulnerability cards and change history.
What criteria are used to assess vulnerabilities?
Vulnerabilities are evaluated using the international CVSS v4.0 standard by severity: critical, high, medium, and low. This enables risk-based prioritization to address the most dangerous threats first.
Additionally, BI.ZONE EASM incorporates the exploit prediction scoring system (EPSS) metric to estimate the likelihood for a specific vulnerability to be exploited in the wild within the next 30 days.
What systems does BI.ZONE EASM integrate with?
BI.ZONE EASM data can be integrated with your SOC, SIEM, SOAR, and ticketing systems to automate incident response. Insights into vulnerabilities, asset inventory, and remediation statuses help streamline your vulnerability management and incident response workflows.
Does my data remain confidential with BI.ZONE EASM?
Yes, it does. BI.ZONE EASM operates as an agentless service and requires no software installation or modifications to your infrastructure. Role- and organization-based access control ensures the highest level of confidentiality and security.
Which organizations is BI.ZONE EASM designed for?
BI.ZONE EASM is particularly valuable for organizations that:
operate multiple websites, domains, or external services
lack complete visibility into their external perimeter (have no active asset inventory and no clear internet-facing footprint)
do not perform regular vulnerability scanning
have previously experienced security incidents or data breaches originating from the external perimeter
operate a distributed infrastructure, including holdings, regional branches, or subsidiaries
Under these conditions, BI.ZONE EASM helps establish systematic control over external assets, proactively identify vulnerabilities, and reduce the risk of attacks.
