Is the discovery intrusive?

No. Discovery is non-intrusive and production-safe, gathering external exposure data without disrupting your services.

Can it find assets we don't know about?

Yes — that is the core value. Unknown, abandoned and forgotten assets are a leading cause of breaches, and surfacing them is exactly what ASM does.

How is ASM different from a vulnerability scan?

ASM first discovers and scores your full external footprint; scanning then checks known hosts for flaws. ASM tells you what to scan in the first place.

Propulsé par ImmuniWeb Discovery

See everything an attacker can see. ImmuniWeb® Discovery automatically detects, maps and classifies your entire external attack surface — on-prem and cloud IT assets, shadow IT and forgotten servers — then continuously monitors them for misconfigurations and exposure, just by entering your company name.

Why Attack Surface Management Is a Business Revenue Lever

You can't protect what you can't see — and most breaches start at an asset nobody knew was exposed. Continuously discovering and scoring your external attack surface shrinks the entry points attackers can use, focuses your security budget on real exposure, and gives enterprise buyers confidence that you have your digital footprint under control.

Unknown and forgotten assets exposed in the wild
Blind spots that attackers find first
Flat lists with no business context
Point-in-time blindness between audits
Bloated testing of an unknown surface

Periodic Asset Inventory vs Continuous Attack Surface Management

	Periodic Inventory	Continuous ASM
Coverage	Ce que vous pensez à répertorier	Everything internet-facing, incl. shadow IT
Freshness	Outdated quickly	Continuously updated
Scoring	Manual, inconsistent	Automated, risk-based
Cloud & Shadow IT	Often missed	Actively discovered
Value	A static spreadsheet	A living, prioritized surface

Recommendation: A one-off asset inventory is stale the moment teams spin up new servers and cloud resources. Continuous ASM keeps your external surface mapped and scored in real time, so exposure is reduced as an ongoing process. ImmuniWeb® Discovery does it just by starting from your company name.

Attack Surface Coverage & Scope

ImmuniWeb® Discovery maps and monitors your external surface across four dimensions:

Asset Discovery & Classification

Domaines, sous-domaines, adresses IP et certificats
Actifs IT sur site et cloud
Shadow IT, serveurs abandonnés et oubliés
Automatic classification and ownership mapping

Exposition et mauvaise configuration

Open ports and exposed services
Exposed admin and management interfaces
Weak or expired TLS and certificates
Misconfigured or outdated assets

Risk Scoring & Prioritization

Risk-based scoring per asset
Priorisation orientée menaces
Low false-positive findings
Focus on the most exploitable exposure

Monitoring & Standards

Continuous monitoring for new exposure
Brand and typosquatting detection
SIEM and workflow integration
Support for DORA, NIS 2 and PCI DSS scoping

External Attack Surface Risk Categories

Domains & Subdomains

We map your full domain footprint, including forgotten ones.

IPs, Ports & Services

We detect exposed services and fingerprint versions.

Cloud Assets

Nous révélons les actifs multi-cloud sur AWS, Azure et GCP.

Shadow IT

We find unknown, abandoned and forgotten assets.

TLS faible ou expiré

We flag certificate and encryption issues.

Exposed Admin Panels

We detect management interfaces reachable online.

Outdated Services

We fingerprint versions and flag known CVEs.

Leaked Secrets

We surface exposed keys and credentials tied to assets.

Brand & Typosquatting

We detect look-alike domains and brand abuse.

Misconfigurations

We flag risky configurations widening exposure.

The Attack Surface Management Lifecycle

Seed & Scope

We start from your company name and seed domains. Artifact: an initial scope and asset seed list.

Phase 1

Phase 2

Discovery & Classification

Nous découvrons et classons chaque actif exposé à Internet. Livrable: un inventaire complet des actifs externes.

Exposure Assessment

We analyze ports, services and misconfigurations. Artifact: an exposure and misconfiguration report.

Phase 3

Phase 4

Scoring des risques

We score each asset by risk. Artifact: a risk-prioritized exposure view.

Alertes et réduction

We alert on critical exposure with guidance. Artifact: actionable alerts to reduce attack surface.

Phase 5

Phase 6

Monitoring continu

We keep watching for new and changed assets. Artifact: ongoing alerts and a current surface map.

Surveillance continue et réduction de la surface d'attaque

Your external surface changes daily as teams launch servers, domains and cloud resources. ImmuniWeb® Discovery continuously monitors it and alerts you to newly exposed assets, services and shadow IT, exporting findings to your SIEM and risk register. Attack-surface reduction becomes a measurable, ongoing program instead of a once-a-year scramble.

Visibilité de la surface d'attaque spécifique au secteur

We tailor discovery to how complex and distributed your footprint is:

Finance & Insurance

External-surface visibility to support DORA and reduce the cost of PCI DSS scoping.

Enterprise & Post-M&A

Shadow IT and cloud discovery across regions, business units and acquisitions.

Public Sector & Healthcare

Continuous monitoring of internet-facing assets handling sensitive data.
