How is this different from a vulnerability scan?

A vulnerability scan checks hosts you already know about. We first discover your full external surface — including shadow IT and cloud — then score every IP and service by risk.

Can it find assets we've forgotten about?

Yes. Discovering shadow, abandoned and forgotten servers and cloud infrastructure is a core part of the assessment and a common source of breaches.

Does it help with PCI DSS?

Yes. A clear, current view of your external surface reduces and accelerates PCI DSS scoping and scanning and supports your compliance evidence.

Warum Netzwerksicherheitsbewertung ein Umsatzhebel ist

You can't protect what you can't see — and forgotten servers, open ports and shadow cloud infrastructure are exactly where breaches start. A continuous, risk-based view of your external network shrinks your attack surface, cuts the cost and scope of pentests and PCI DSS scans, and keeps enterprise buyers confident in your security.

Empfehlung: Ein Vulnerability Scan zeigt Ihnen, was auf den Ihnen bekannten Hosts nicht stimmt. Eine Network Security Assessment identifiziert zunächst Ihre tatsächliche Exposition – einschließlich Shadow IT und vergessener Assets – und bewertet diese dann nach Risiko. Beginnen Sie mit Discovery und Scoring, und konzentrieren Sie Ihr Pentest-Budget dort, wo die echte Exposition liegt.

Comprehensive Network Assessment Scope

We map and assess your external network attack surface across four dimensions, production-safely:

Asset & Service Discovery

External IP, domain and subdomain discovery
Open-port detection across the full range
Smart fingerprinting of running services and versions
Shadow IT, abandoned and forgotten servers

Exposure & Configuration

Publicly exposed admin and management interfaces
Insecure SSH/RDP and remote-access exposure
TLS/SSL configuration and certificate review
Exponierte Datenbanken und Speicherdienste

Vulnerability & Risk Scoring

Outdated services with known CVEs
Risk-based scoring per IP address and service
Production-safe analysis with no service disruption
Prioritization to reduce attack surface

Cloud, Shadow IT & Standards

Shadow cloud infrastructure discovery
Multi-environment (on-prem + cloud) coverage
Continuous monitoring for new exposure
Support for PCI DSS scoping and scanning

Network Attack Surface Risk Areas

Exposed Open Ports

Wir erkennen jeden offenen Port und den dahinterstehenden Dienst.

Outdated Services & CVEs

Wir ermitteln Versionen und markieren bekannte Schwachstellen.

Shadow IT & Vergessene Server

We surface assets no one is tracking or patching.

Exposed Admin Interfaces

We flag management panels reachable from the internet.

Insecure Remote Access

We detect weak or exposed SSH, RDP and VPN endpoints.

Weak TLS/SSL

We review certificates and protocol/cipher configuration.

Exponierte Datenbanken

— We find publicly reachable databases and data stores.

Shadow Cloud Infrastructure

We discover untracked cloud assets widening exposure.

Misconfigured Services

We flag risky service configurations and defaults.

Attack-Surface Drift

We continuously detect newly exposed or changed assets.

The 6-Phase Network Assessment Workflow

Scoping & Onboarding

Wir vereinbaren die IP-Bereiche, Domains und Umgebungen im Scope. Ergebnis: ein Scope-Dokument und eine Asset-Liste.

Phase 1

Phase 2

Asset & Surface Discovery

We discover external assets, including shadow IT and cloud. Artifact: a complete external attack-surface inventory.

Port & Service Fingerprinting

We analyze every open port and identify service and version. Artifact: a fingerprinted service map.

Phase 3

Phase 4

Risk Scoring & Validation

We score each IP and service by risk, validated by analysts. Artifact: a risk-prioritized, false-positive-free findings list.

Berichterstattung und Behebungsempfehlungen

You receive an audit-ready report with clear priorities. Artifact: report mapped to PCI DSS and your risk register.

Phase 5

Phase 6

Kontinuierliche Überwachung

We keep watching for new exposure and changes. Artifact: ongoing alerts and an updated attack-surface view.

Continuous Monitoring & Attack Surface Reduction

Die Netzwerkexposition ändert sich täglich, da Teams Server und Cloud-Ressourcen einrichten. ImmuniWeb® Discovery überwacht kontinuierlich Ihre externe Angriffsfläche und warnt Sie vor neu exponierten Ports, Diensten und Shadow-Assets – so wird die Reduzierung der Angriffsfläche zu einem fortlaufenden, messbaren Prozess anstatt zu einem einmal-jährlichen Audit. Die Ergebnisse werden zur Maßnahme in Ihr SIEM und Ihr Risikoregister exportiert.

Branchenspezifische Threat Modeling im Netzwerk

Network exposure risk is not one-size-fits-all. We tailor the assessment to your sector:

Finance & Payments

External-surface and segmentation visibility to support PCI DSS scoping and reduce the cost of compliance scanning.

Manufacturing & Critical Infrastructure

Discovery of exposed OT-adjacent services and remote-access endpoints aligned with NIS 2 and IEC 62443 concerns.

Enterprise & Multi-Cloud

Shadow IT and shadow-cloud discovery across mergers, regions and business units to eliminate blind spots.

Häufig gestellte Fragen

Q

Wird die Bewertung mein Netzwerk beeinträchtigen?

A

Nein. Unser Scanning ist von Design her nicht-intrusiv und production-safe – es sammelt das, was Sie benötigen, ohne Ihre Dienste zu verlangsamen oder zu stören.
Q

Inwiefern unterscheidet sich dies von einem Vulnerability Scan?

A

A vulnerability scan checks hosts you already know about. We first discover your full external surface — including shadow IT and cloud — then score every IP and service by risk.
Q

Can it find assets we've forgotten about?

A

Ja. Das Aufspüren von Schatten-IT, verlassenen und vergessenen Servern sowie Cloud-Infrastruktur ist ein zentraler Bestandteil der Bewertung und eine häufige Ursache für Sicherheitsverletzungen.
Q

Does it help with PCI DSS?

A

Yes. A clear, current view of your external surface reduces and accelerates PCI DSS scoping and scanning and supports your compliance evidence.
