External Attack-Surface Management (EASM)
Continuously enumerate internet-facing IP blocks, cloud gateways, and open service ports to eliminate unknown or forgotten infrastructure exposures.
How the sector deploys itNetworkIntel
Examine publicly observable IP addresses, network ranges and internet-facing assets to build a clearer view of external exposure: identify exposed services, validate asset ownership, map network relationships, support attack-surface management and prioritise defensive action within explicitly authorised scope.

What it is
IP address, network and exposed asset intelligence for security and infrastructure teams
NetworkIntel helps organisations examine publicly observable IP addresses, network ranges and internet-facing assets to build a clearer view of their external exposure. By bringing together relevant network and asset information, it can support attack-surface management, infrastructure inventory, threat intelligence and authorised security assessments.
Understanding which assets are visible from the internet is an important step in identifying unknown services, validating ownership and prioritising defensive action. NetworkIntel is designed to make network information easier to interpret and investigate, helping security teams move from scattered technical indicators to a more organised picture of their external environment.
Capabilities may include IP and network analysis, exposed-asset discovery, relationship mapping and structured findings; discovery results should be validated and testing must remain within explicitly authorised scope.
Key capabilities include IP address and network-range analysis, discovery of publicly exposed assets, and external attack-surface visibility and reporting.

The principle
Why disciplined network asset intelligence belongs in your toolkit
Moving from fragmented IP lists to structured, defensible and context-rich attack-surface management.
- Visibility across the full network boundary
- Organisations cannot defend what they do not know exists. NetworkIntel maps complete CIDR prefixes and autonomous systems to ensure no internet-facing asset remains hidden.
- Context beyond isolated IP addresses
- An IP address in isolation reveals little. NetworkIntel correlates routing announcements, open service banners, and parent domains into an interconnected topology graph.
- Strict adherence to authorised scope
- External security assessments must operate with legal precision. NetworkIntel embeds strict boundary guardrails so discovery stays firmly within approved corporate and regulatory bounds.
- Analyst command over attack-surface decisions
- Automated analysis surfaces exposed ports and services, but experienced security analysts decide the remediation priority. Findings are presented with full provenance for auditable decisions.
