Continuously Discover Your External Attack Surface
Gain complete visibility of your internet-facing assets. Automate the discovery of shadow IT, map your digital footprint, and establish a real-time inventory of your external exposure.
External Asset Discovery (EASM)
External Attack Surface Management is the discovery and monitoring layer of the Teisoft Exposure Platform™. It continuously identifies internet-facing assets, shadow IT, exposed services, and architectural changes across your external footprint. The platform eliminates visibility gaps by attributing rogue or forgotten assets to your organization and passing them directly into automated prioritization and validation workflows.




















Engineered for Continuous Scope Definition
Business-Centric Scope Definition
Categorize and group your external assets based on business criticality, environment context (Production, Staging, Dev), and operational impact. Prioritize exposure where it hurts your business most.
Subsidiary, M&A & Supply Chain Footprint
Gain complete visibility into sub-brands, newly acquired entities, and third-party vendor integrations. Ensure your security scope expands dynamically as your business evolves.
Engineered for Continuous Asset Discovery
Continuous Asset & Shadow IT Discovery
Automatically discover and map your entire external attack surface, tracking domains, subdomains, and public IPs to eliminate security blind spots and improve visibility.
Exposed Credentials & Secrets Detection
Uncover unauthorized, forgotten, or legacy internet-facing assets before attackers do, reducing hidden risks and ensuring stronger security governance.
Service & Port Monitoring
Continuously monitor exposed ports, services, and protocols to quickly identify risky changes, minimize exposure, and prevent potential attack paths.
Domain & Certificate Monitoring
Continuously monitor domains, DNS records, and SSL/TLS certificates to prevent service disruptions, reduce misconfiguration risks, and maintain a trusted digital presence.
Why Static Asset Inventories Fall Behind
The Perimeter Deficit
Domains, cloud services, temporary environments, acquisitions, and assets created outside centralized IT processes can quickly make static inventories incomplete.
Dynamic Infrastructure Risks
Cloud resources, temporary testing environments, third-party integrations, and new applications can appear or change faster than manual inventory processes can track.
Compliance Deficiencies
Security and compliance programs depend on an accurate understanding of in-scope assets. Incomplete inventories can weaken testing coverage, remediation tracking, and audit evidence.
FAQs
What is External Asset Discovery?
External Asset Discovery is the process of identifying and organizing the internet-facing assets that may expose an organization to cyber risk.
Teisoft Exposure Platform™ helps organizations build a centralized inventory of authorized external assets so security and IT teams can understand what is publicly accessible, who is responsible for it, and which systems require further assessment.
What types of external assets can be managed in the platform?
The platform can be used to manage internet-facing assets such as domains, subdomains, public IP addresses, servers, websites, web applications, APIs, and other externally accessible systems included within the authorized scope.
Can Teisoft help identify assets that our organization is not actively tracking?
Yes. External asset discovery is intended to help uncover systems that may not appear in an organization’s current inventory, including forgotten infrastructure, legacy services, temporary environments, and assets created outside established IT processes.
These assets are sometimes described as shadow IT. Identifying them allows the organization to confirm ownership, determine whether they are still required, and decide whether they should be assessed, secured, or decommissioned.
Does External Asset Discovery require installing agents?
No. External Asset Discovery evaluates the organization from an external perspective and does not require agents to be installed on every internet-facing asset.
This helps reveal what an attacker may be able to observe from outside the organization, including systems that may not be covered by internal endpoint or vulnerability management tools.
How does Teisoft prevent unrelated assets from being added to our inventory?
Discovery results should be reviewed and validated before they are treated as confirmed organizational assets.
Teisoft Exposure Platform helps teams maintain a distinction between discovered assets, confirmed assets, and the authorized scope for security assessment. Ownership and business context can be reviewed by the customer, by Teisoft specialists under the Teisoft-Managed model, or through an agreed validation process.
This reduces the risk of scanning or managing infrastructure that does not belong to the organization.
How often is the external asset inventory updated?
The inventory can be updated as the organization adds, removes, or discovers internet-facing systems.
Because external attack surfaces change over time, asset discovery should not be treated as a one-time exercise. New domains, cloud services, public servers, applications, or third-party deployments can introduce new exposures between traditional annual assessments.
The appropriate discovery and review frequency can be aligned with the organization’s rate of change and risk profile.
Does adding a newly discovered asset increase our subscription cost?
No. Teisoft does not charge according to the number of assets stored in the platform.
Newly discovered or confirmed assets can be added to the inventory without automatically increasing the subscription price. Scanning those assets uses the scanning capacity included in the selected monthly plan.
This allows organizations to maintain a more complete external asset inventory and decide how frequently each asset should be scanned based on risk, rather than excluding assets to avoid per-asset licensing costs.
What types of external assets and exposures can Teisoft discover?
Our platform discovers a broad spectrum of external exposures, including:
IP addresses, subnets, and open ports
Domains, subdomains, and DNS configurations
Multi-cloud infrastructure (AWS, Azure, GCP) and storage buckets
Exposed API endpoints and web applications
Leaked corporate credentials and exposed secrets/keys
SSL/TLS certificates and domain lookalikes (typosquatting)
