External Attack Surface Management

External Attack Surface Management with QSEIDON ATLAS

QSEIDON ATLAS helps organizations identify publicly visible assets, understand external risk and prioritize action before vulnerabilities can be exploited.

See what hackers see – and stay ahead of them.

First findings within 1 business day

Typical onboarding window

Your external attack surface changes every day.

New domains, cloud resources, certificates, publicly reachable services and forgotten systems can appear without central security teams knowing about them. Attackers continuously scan for exactly these gaps. QSEIDON ATLAS reveals where your organization is vulnerable to attack from the outside.

Unknown Assets

Internet-facing assets and services can exist for a long time before being captured internally.

Shadow IT

Teams adopt tools, domains and services faster than central governance can document them.

Technical Noise

A list of CVEs or open services doesn't automatically reveal what matters most to the business.

Continuous Change

Your external footprint is constantly changing, making point-in-time visibility unreliable.

What you can understand with QSEIDON ATLAS

ATLAS turns scattered external findings into a clear picture of your risk – and shows you where to act first.

Full Visibility

From domains and subdomains to cloud-hosted assets, technologies in use, and known vulnerability indicators – ATLAS reveals what's visible from the outside and where risk can emerge.

Risk Prioritization

Translate external findings into a clear 0–100 risk score based on severity, exploit likelihood, finding age and known exploit availability.

Continuous Monitoring

Track changes over time, stay on top of new risk signals and collaborate through integrated team sharing.

Executive and Technical Reporting

Communicate external risk clearly to technical teams and management with structured, action-oriented reporting.

A risk score based on real external findings

ATLAS doesn't reduce cyber risk to a vague label. It uses visible external findings and combines technical severity with exploit likelihood and context into a clear 0–100 outside-in picture.

Capture outside-in signals

ATLAS helps surface externally visible signals such as assets, certificates, CVEs and threat-relevant context.

Prioritize real risk

The score factors in CVSS, EPSS, finding age and known exploit availability – helping teams focus beyond raw severity alone.

Communicate clearly

Translate technical findings into a management-ready view that enables prioritization of remediation actions.

Built to support decisions without hiding the evidence behind them.

Where teams use ATLAS first

Initial Exposure Assessment

Gain a structured first overview of your external attack surface and your starting position.

Continuous Monitoring

Track changes to your external footprint and detect new risks early.

Pentest Scoping

Use ATLAS findings to focus penetration tests on the most relevant and at-risk assets.

Cloud Risk Review

Identify cloud-hosted assets and services that are externally visible but not centrally tracked.

Subsidiaries & Acquisitions

Quickly assess the external risk posture of subsidiaries or acquisition targets.

Executive Risk Reporting

Translate technical external findings into a management-ready risk view for leadership conversations.

Who ATLAS is built for

IT Leaders

Gain a clearer external risk picture without having to introduce heavyweight enterprise tools.

Security Leads

Prioritize real external risk more clearly than with a raw list of technical findings.

Infrastructure Teams

Understand what's visible from the outside and where action is needed first.

Founders & Executives at Smaller Companies

Use a more accessible risk view to support security discussions and decisions.

Why QSEIDON ATLAS feels different

ATLAS is built for organizations that need external cyber risk transparency – easier to understand and faster to act on than heavyweight enterprise platforms.

  • Risk-first, not asset-first
  • Management-ready score based on evidence
  • Built for SMBs and mid-market, not enterprise complexity
  • Self-service SaaS with guided support on request

Risk-first

Not asset-inventory-first

Continuous

No point-in-time snapshots

SMB-fit

No enterprise complexity

Self-service

With expert support on request

ATLAS helps translate external visibility into clearer decisions – without pretending to be everything at once.

Clear about what it is

Knowing what a product wasn't built for is part of using it correctly.

From Visibility to Prioritization

ATLAS classifies externally visible risk and shows what matters most. For an in-depth technical assessment of individual systems, we recommend a targeted penetration test from Qseidon afterwards.

Not a Remediation Platform

ATLAS is designed for discovery, visibility and prioritization – not remediation workflows.

The Best Starting Point, Not the Last Step

ATLAS gives you a solid foundation for prioritization. For complete coverage of individual critical systems, a targeted penetration test from Qseidon completes the picture.

Not a Data Pile Without Value

The goal is clarity and prioritization – not just more findings on a screen.
