Attack Surface
Management (ASM)

Security Through the Attacker's Perspective

Designing stronger defense through the attacker's perspective

Continuous Visibility
into Exposure

Attack Surface Management continuously tracks changes across your attack surface — new assets, emerging vulnerabilities, configuration drift — to identify and address security risk early.

Market Needs & Client Challenges

Exposure Gaps,
Growing Attack Paths

Unmanaged Assets
& Shadow IT Exposure

Externally exposed assets that an organization is unaware of become blind spots in security management.
Test servers and unregistered cloud assets can become initial intrusion paths through missing patches, misconfigurations, and expired certificates.

Critical Vulnerabilities,
Delayed Action

The moment a new vulnerability is disclosed, quickly identifying affected assets and remediation priorities determines the speed of response.
When a new CVE or zero-day issue arises, manually checking assets, versions, and the responsible teams can delay response after an exploit is published.

Extended Attack Surface
& Supply Chain Risk

An external attack surface that extends to affiliates and partners can transfer into a security risk for headquarters.
Neglected web services, APIs, and VPNs of affiliates and partners can become entry paths for supply chain attacks.

What is Attack Surface Management (ASM)?

Attack surface management (ASM) is the activity of continuously identifying an organization's externally exposed assets and vulnerabilities from the attacker's perspective and managing them on a risk basis. Analyzing the exposure status of domains, subdomains, IPs, web services, and cloud assets, along with vulnerabilities, misconfigurations, and certificate expirations, to visualize Shadow IT and neglected assets and present response priorities.

External Asset Visibility

Continuously identifying externally exposed domains, IPs, web services, and cloud assets.

Exposure Risk Analysis

Analyzing per-asset risk factors such as vulnerabilities, misconfigurations, certificate expirations, and exposed ports. When new CVEs or zero-days emerge, identifying the affected assets and presenting priority remediation targets based on exploitability and asset criticality.

Business-critical Exposure Prioritization

Not all external exposure carries the same risk. By combining asset criticality, service connectivity, exposure level, and vulnerability exploitability, we identify the items that require the most urgent response first.

Know Your Attack Paths, Fix What Matters First

Actionable Vulnerability Intelligence

Identifying the vulnerabilities most likely to lead to actual attacks first. S2W's TALON SCORE analyzes real attack signals and exploitability, then combines this with externally exposed asset information and asset criticality to present remediation priorities tailored to each organization.

Leaked Credentials, Real Attack Paths

By cross-analyzing leaked accounts detected on hidden channels with ASM asset information, S2W interprets simple external exposure as attack paths with real intrusion potential. Analyzing account privileges, accessible services, and associated assets and vulnerabilities together to identify priority response points.
