See Your Network Through an Attacker's Eyes

Most organizations know their perimeter, but very few truly understand their internal attack surface. Prowler acts like an internal attacker, moving laterally through your network to expose weak points and misconfigurations.

It helps security and infrastructure teams identify hidden risks, forgotten services and dangerous configurations before they are exploited.

Internal network crawling

Attack surface discovery

Automated risk mapping

Continuous monitoring

Deep Network Scanning Capabilities

Prowler combines network scanning, service detection and behavioral analysis to map your internal environment.

TCP and UDP port scanning with intelligent throttling

Service and application fingerprinting

Detection of outdated or vulnerable services

Identification of lateral movement opportunities

Anomaly and malware communication pattern detection

Automated vulnerability assessment and risk scoring

Identify Potential Attack Paths

Beyond scanning, Prowler analyzes how an attacker could exploit your internal environment.

Maps potential lateral movement routes

Identify how attackers can move between systems and gain deeper network access through existing connections.

Highlights privilege escalation risks

Detect vulnerable configurations that could allow attackers to elevate permissions and access critical resources.

Detects overly exposed network segments

Find network areas with excessive exposure that increase your attack surface and vulnerability to intrusion.

Shows compromised path simulations

Visualize potential attack scenarios and understand how breaches could propagate through your infrastructure.

Designed for Secure Environments

Prowler runs entirely on your infrastructure and respects your security boundaries.

All scanning and data processing remain inside your network
Supports segmented and air-gapped networks
Role-based access control
Full audit and activity logging

Real-Time Network Visibility

Security teams need visibility, not just reports. Prowler provides live views into your network landscape.

Live network map with hosts and services

Interactive real-time visualization of your entire network topology, showing active hosts, running services, and their connections.

Risk severity categorization

Automated risk scoring and categorization helps prioritize vulnerabilities based on their potential impact and exploitability.

Vulnerability trends over time

Track how your security posture evolves with historical trend analysis and vulnerability lifecycle management.

Alerts on critical exposures

Instant notifications for critical security exposures, misconfigurations, and newly discovered vulnerabilities requiring immediate attention.
