Attack surface assessment
Gain complete visibility into your external footprint: Every domain, cloud instance, and exposed asset that shapes your digital risk.
Your attack surface extends far beyond your firewall. Rhymetec’s External Attack Surface Assessment uncovers everything connected to your organization across the internet—from public infrastructure to leaked information tied to your brand. Our analysts combine technical reconnaissance and open-source intelligence (OSINT) to map your external presence and highlight exposures. The result is a clear picture of your digital risk—and an actionable plan to reduce it.

Comprehensive external visibility, without the guesswork
A single assessment that reveals what’s exposed, what’s at risk, and how to fix it.
Attack surface assessment
Rhymetec’s Attack Surface Assessment goes beyond traditional scanning by combining technical asset discovery with intelligence-driven analysis of your external digital footprint.
We identify:
- Public-facing domains, IPs, subdomains, and forgotten cloud instances
- Misconfigured or outdated systems exposed to the internet
- Shadow IT or abandoned assets that expand your risk surface
- Leaked credentials, brand impersonations, and sensitive data tied to your organization
- Employee or company data exposure across the open, deep, and dark web
A premium process for complete external awareness
We combine EASM and OSINT techniques to reveal your true digital footprint — and the risks that come with it.
Asset Discovery & Mapping
We identify all internet-connected assets associated with your organization, including registered domains, cloud environments, IPs, and third-party services.
Exposure Analysis
Our analysts detect vulnerabilities, misconfigurations, and outdated systems that expand your external risk surface.
Intelligence Correlation
Using OSINT and dark web monitoring, we uncover leaked credentials, data exposures, and impersonation attempts related to your brand or employees.
Risk Prioritization
Every finding is ranked by severity and business impact, helping your team focus remediation where it matters most.
Reporting & Recommendations
You receive a comprehensive, intelligence-driven report outlining exposures, associated risks, and specific mitigation steps to strengthen your external security posture.
From discovery to direction
Every engagement concludes with a comprehensive risk intelligence package tailored to your organization.
- Complete asset inventory across internet-facing infrastructure
- Exposure summary and risk scoring by category
- OSINT and dark web intelligence findings
- Executive report with key insights and business impact overview
- Technical report with prioritized recommendations
- Optional follow-up workshop to align remediation priorities and establish continuous monitoring
When to choose an external attack surface assessment
An Attack Surface Assessment is ideal for organizations looking to understand and reduce their exposure before something—or someone—finds it first.
Before a penetration test or audit to establish a clear baseline
During mergers, acquisitions, or divestitures
When expanding into new cloud environments or global regions
To assess third-party or brand exposure across digital ecosystems
As part of continuous monitoring or threat intelligence initiatives

What is EASM?
External Attack Surface Management (EASM) is a cybersecurity practice that continuously discovers, monitors, and evaluates everything an organization has exposed to the internet—such as domains, IPs, subdomains, cloud assets, and public data. The goal of EASM is to provide ongoing visibility into external risks so companies can detect new exposures, prioritize remediation, and reduce their overall attack surface.
While true EASM involves continuous monitoring and automated discovery, Rhymetec’s External Attack Surface Assessment offers a point-in-time version of that same visibility. It provides a comprehensive snapshot of your external footprint, helping you understand what’s exposed before you invest in continuous management.
Why choose an attack surface assessment over External Attack Surface Management (EASM)?
Organizations often begin with an attack surface assessment to gain a clear, measurable understanding of their current external exposure before investing in continuous management. This approach provides immediate, actionable insights—revealing misconfigurations, exposed systems, or leaked data that expand your risk surface.
For many teams, a one-time assessment delivers exactly what’s needed to prepare for penetration testing, compliance audits, or cloud security improvements. It’s a focused way to uncover hidden assets and risks without committing to a full-time monitoring platform.
How does an attack surface assessment differ from External Attack Surface Management (EASM)?
An attack surface assessment is a one-time evaluation. It’s ideal for establishing a baseline of your external exposure, identifying forgotten or misconfigured assets, and assessing digital risk before an audit, penetration test, or merger.
In contrast, EASM is an ongoing managed service that continuously scans and tracks changes to your external footprint. It uses automation and threat intelligence to detect new assets or exposures as they appear.
Rhymetec’s assessment delivers the same level of depth and intelligence you’d expect from EASM—just focused on giving you a clear, actionable starting point.
How long does an External Attack Surface Assessment take?
Most External Attack Surface Assessments are completed within one to two weeks, depending on your organization’s size and the number of assets discovered.
