Discover unknown assets, monitor exposed ports, and continuously map your digital footprint with CyberFurl's automated Attack Surface Management platform.
You cannot protect what you do not know exists. In the modern era of multi-cloud deployments, decentralized DevOps, and shadow IT, your external attack surface is expanding faster than your security team can track it. Every forgotten staging server, exposed database, and orphaned IP address is a massive liability waiting to be exploited. The CyberFurl Attack Surface Management Platform provides relentless, continuous visibility into your true digital footprint. We continuously scan the global internet to discover your unknown assets, identify exposed vulnerabilities, and allow you to see your network exactly as an attacker sees it—before they strike.

The concept of a secure, defendable network perimeter is dead. Ten years ago, the CISO knew exactly where the perimeter was because all servers were physically racked in a single data center behind a monolithic firewall.
Today, the perimeter is entirely porous. A marketing manager can spin up a WordPress site on DigitalOcean with a corporate credit card. A developer can provision an AWS EC2 instance for a quick test and forget to tear it down before the weekend. Through mergers and acquisitions, enterprises inherit massive, undocumented networks spanning dozens of hosting providers.
This phenomenon—Shadow IT and Orphaned Infrastructure—creates an invisible, unmanaged attack surface. These assets bypass the corporate firewall. They are not enrolled in the corporate endpoint detection and response (EDR) platform. They are not scanned by the vulnerability management team. They sit on the public internet, unpatched, often running default credentials, waiting to be found by automated botnets and ransomware syndicates.
For decades, the security industry has tried to solve the asset inventory problem using rigid, internal tools that fundamentally fail in a dynamic, cloud-native world.
Organizations spend millions deploying Configuration Management Databases (CMDBs) like ServiceNow. However, CMDBs rely on manual data entry or agents deployed to known servers. If a developer bypasses the standard provisioning process to spin up a server in a rogue AWS account, that server will never appear in the CMDB. The CMDB only shows you the network you think you have.
Vulnerability scanners are powerful, but they require a definitive list of target IP addresses to scan. They operate under the assumption that the IT department already possesses a perfect inventory. An attacker does not have this limitation; they scan the entire internet and pivot based on what they find. If you don't feed the shadow IT IP address into the scanner, the vulnerability goes undetected.
Relying on an annual penetration test to map your attack surface is a recipe for disaster. A pen tester might find 50 exposed assets in January. But if a developer exposes a MongoDB database in February, you will remain vulnerable for 11 months until the next annual test. In cybersecurity, time is the enemy.
The failure to manage the external attack surface is the root cause of the most devastating data breaches of the modern era.
The CyberFurl Attack Surface Management Platform is a continuous, automated discovery engine that maps your digital perimeter with unparalleled precision.
We do not wait for you to tell us what you own. You provide us with a handful of seed domains (e.g., yourcompany.com). CyberFurl utilizes recursive DNS crawling, Certificate Transparency (CT) log analysis, and autonomous system number (ASN) mapping to discover thousands of related domains, subdomains, and IP addresses scattered across the internet.
The platform excels at finding the assets you didn't know existed. We identify staging environments, forgotten UAT servers, and marketing microsites hosted on unauthorized third-party infrastructure. We highlight these assets so your security team can bring them under management or decommission them.
Once an asset is discovered, CyberFurl continuously scans it to determine exactly what services are exposed to the public internet. We identify open SSH (22), RDP (3389), database ports (MySQL, PostgreSQL, MongoDB), and legacy administrative interfaces, allowing you to close critical firewall gaps instantly.
We analyze the HTTP responses and TLS certificates of your exposed web assets to dynamically fingerprint the underlying technology stack. We tell you exactly which servers are running vulnerable versions of Apache, Nginx, PHP, or outdated WordPress plugins, providing actionable intelligence to your vulnerability management team.
During an acquisition, time is critical. CyberFurl allows you to input the target company's seed domains and instantly generate a comprehensive report of their external attack surface. You can identify critical vulnerabilities and calculate the cost of remediation before the deal closes, providing immense leverage during negotiations.
CyberFurl approaches Attack Surface Management from the perspective of a highly sophisticated, persistent attacker.
When you deploy the platform, there are no agents to install and no complex API integrations required to begin the initial discovery phase. The entire process is external, non-intrusive, and highly scalable.
Our engine continuously indexes the IPv4 space. When we attribute an IP address or subdomain to your organization, it enters your active inventory dashboard. But we don't stop at discovery. We apply a contextual risk scoring algorithm to every asset.
An exposed web server running an up-to-date Nginx instance is noted, but deprioritized. However, if CyberFurl detects a newly spun-up AWS EC2 instance running a forgotten Jenkins server with port 8080 exposed to the internet, the system flags it as a Critical Risk. The platform automatically generates an alert, pushes it via webhook to your SIEM or Jira instance, and provides the exact IP address and port data required for the DevOps team to instantly apply a blocking Security Group rule.
[!IMPORTANT] Comparison Callout: CyberFurl vs. Internal Scanners Internal tools like Tenable or Qualys are essential for deep, authenticated vulnerability scanning of known assets. CyberFurl EASM sits outside your network. We are the wide-angle lens that finds the assets your internal scanners are blind to, ensuring your vulnerability management program actually covers 100% of your perimeter.
Deploying the CyberFurl EASM platform is instantaneous and requires zero engineering overhead.
Maintaining an accurate inventory of assets is not just a best practice; it is the absolute foundation of every major cybersecurity compliance framework.
The tactical advantages of deploying a continuous Attack Surface Management platform fundamentally shift the operational reality of your Security Operations Center (SOC).
The Return on Investment for the CyberFurl Attack Surface Management platform is easily quantified through risk reduction, operational efficiency, and M&A acceleration.
Organizations utilizing the CyberFurl EASM platform report immediate, measurable transformations in their security posture within the first week of deployment.
An ASM platform continuously discovers, inventories, and monitors all internet-facing assets belonging to an organization. It identifies unknown servers, exposed databases, open ports, and shadow IT infrastructure that security teams are unaware of.
Vulnerability scanners (like Nessus) require you to tell them exactly which IP addresses to scan. EASM tells you which IPs you own in the first place. You cannot scan an asset if you don't know it exists.
Stop guessing what your perimeter looks like. See your network exactly as an attacker sees it.
Discover forgotten subdomains, shadow IT, and exposed databases in minutes.
Run Your Free Attack Surface ScanYes. CyberFurl's attack surface management platform is cloud-agnostic. We map your external perimeter whether your assets are hosted on AWS, GCP, Azure, DigitalOcean, or on-premises data centers.
We utilize advanced attribution algorithms. We don't just blindly associate an IP based on a generic WHOIS record. We cross-reference TLS certificates, DNS zone data, and autonomous system numbers (ASNs) to guarantee the asset belongs to your organization with mathematical certainty.
No, but it drastically improves it. An annual penetration test is a point-in-time assessment. EASM provides continuous visibility year-round. Providing your EASM inventory to your pen-testers allows them to focus on deep exploitation rather than wasting time on basic asset discovery.
