External Attack Surface Management (EASM)
External Attack Surface Management Overview
Discover Your Exposure. Understand Your Risk. Reduce Your Attack Surface.
External Attack Surface Management continuously discovers and monitors your organisation’s internet-facing assets, helping uncover unknown systems, vulnerabilities, misconfigurations, cloud exposures, and other weaknesses before attackers can exploit them.
DISCOVER
External Assets
Continuously identify domains, IPs, applications, cloud resources, internet-facing systems, and unknown assets.
ASSESS
Risk & Attack Paths
Score and prioritise exposures while mapping relationships between assets to understand potential attack paths.
MONITOR
Attack Surface Changes
Track your external environment for newly exposed assets, services, infrastructure changes, and emerging areas of exposure.
PRIORITISE
Threat-Informed Risk
Correlate exposures with active threats and real-world intelligence to identify which assets and weaknesses require attention first.
IDENTIFY
Vulnerabilities & Exposures
Detect open ports, insecure configurations, outdated software, vulnerabilities, and cloud misconfigurations across exposed assets.
REDUCE
External Attack Surface
Turn exposure insights into prioritised remediation actions that help continuously reduce your organisation’s external attack surface.
Know What’s Exposed Before Attackers Do.
Continuous Discovery • External Visibility • Exposure Detection • Risk Prioritisation • Threat Intelligence • Attack Surface Reduction
The Threat Landscape
As organisations expand across cloud platforms, internet-facing applications, remote infrastructure, third-party connections, and digital services, their external attack surface continues to grow and change. Unknown assets, shadow IT, open ports, vulnerable systems, and security misconfigurations can create hidden entry points that attackers actively search for and exploit.
Without continuous visibility, organisations may struggle to know what is exposed, where vulnerabilities exist, and which risks require immediate attention. External Attack Surface Management continuously discovers and monitors internet-facing assets, identifies exposures, maps potential attack paths, and applies risk and threat context to help organisations prioritise weaknesses and reduce their external attack surface before attackers can take advantage of it.
Attack Surface Growth
YOUR EXTERNAL ATTACK SURFACE IS CONSTANTLY CHANGING
Unknown & Exposed Assets
New domains, cloud resources, applications, services, and internet-facing systems can appear over time. Without continuous discovery, unknown or unmanaged assets may remain exposed and create potential entry points for attackers.
Hidden Exposure
WHAT YOU DON’T KNOW CAN INCREASE YOUR RISK
Vulnerabilities & Misconfigurations
Open ports, outdated software, insecure configurations, and cloud misconfigurations can expose critical systems to attack. Continuous assessment helps identify these weaknesses before attackers have an opportunity to exploit them.
Threat Context
NOT EVERY EXPOSURE PRESENTS THE SAME LEVEL OF RISK
Risk Prioritisation
Understanding severity alone is not enough. EASM combines risk scoring, attack surface mapping, and threat intelligence to identify potential attack paths and prioritise exposures based on their risk and real-world threat activity.

External Attack Surface Management
EASM continuously discovers and monitors internet-facing assets, detects vulnerabilities and exposures, maps relationships, and applies threat intelligence to help organisations understand their external attack surface and reduce potential attack vectors before they are exploited.

Frequently Asked Questions (FAQs)
1. What is External Attack Surface Management (EASM) ?
External Attack Surface Management continuously discovers, monitors, and assesses your organisation’s internet-facing assets and external digital footprint, helping identify unknown assets, exposures, vulnerabilities, and security weaknesses before attackers can exploit them.
2. What types of assets can EASM discover and monitor ?
EASM can provide visibility across domains, IP addresses, applications, cloud resources, internet-facing infrastructure, externally exposed on-premises systems, and third-party connected assets, including previously unknown or shadow IT assets.
3. How does EASM help identify security risks ?
EASM continuously examines externally exposed assets for open ports, insecure configurations, outdated software, vulnerabilities, cloud misconfigurations, and newly exposed services, helping security teams identify weaknesses across the external attack surface.
