Unknown Exposure
Internet-facing assets and services can exist for a long time before being captured internally.
External Attack Surface Management
External Attack Surface Management with QSEIDON ATLAS
QSEIDON ATLAS helps organizations identify exposed assets, understand external risk and prioritize action before vulnerabilities can be exploited.
Discover, assess and monitor your external attack surface from an attacker's perspective.

First findings within 1 business day
Typical onboarding window
Your external attack surface changes every day.
New domains, cloud resources, certificates, exposed services and forgotten systems can appear without central security teams knowing about them. Attackers continuously scan for these exposures. QSEIDON ATLAS helps you see your organization the way attackers see it.
Shadow IT
Teams adopt tools, domains and services faster than central governance can document them.
Technical Noise
A list of CVEs or exposed 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 translates outside-in visibility into a clearer picture of risk – helping teams move from raw signals to better decisions.
Asset Discovery
Gain visibility into external exposure signals such as domains, subdomains, certificates and exposed services of your organization.
Domain and Subdomain Discovery
Identify the full scope of your internet-facing domain infrastructure, including forgotten or unmonitored subdomains.
Cloud Exposure Detection
Surface cloud-hosted assets and services that are visible from the outside and can introduce unexpected risk.
Service and Technology Fingerprinting
Understand which technologies and services are visible from the outside and what attack surface they represent.
External Vulnerability Indicators
Explore CVEs, CVSS scores, certificate information, threat intelligence signals and indicators such as TOR, VPN or proxy relevance.
Risk Prioritization
Translate external findings into a clear 0–100 risk score based on severity, exploit likelihood, exposure 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 exposure context into a clear 0–100 outside-in picture.
Capture outside-in signals
ATLAS helps surface external exposure signals such as assets, certificates, CVEs and threat-relevant context.
Prioritize real exposure
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 supports prioritization and discussion.
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 exposures early.
Pentest Scoping
Use ATLAS findings to focus penetration tests on the most relevant and exposed assets.
Cloud Exposure 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 exposure 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

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.
Not a Vulnerability Scanner
ATLAS helps interpret externally visible risk. It shouldn't be described as a scanner.
Not a Remediation Platform
ATLAS is designed for discovery, visibility and prioritization – not remediation workflows.
No Promise of Complete Discovery
ATLAS doesn't claim full visibility into all assets or attack paths.
Not a Data Pile Without Value
The goal is clarity and prioritization – not just more findings on a screen.
