External Attack Surface Management

Continuous Vulnerability Scanning for Web, API and External Assets

Our external attack surface management service helps security teams identify vulnerabilities across web applications, APIs and internet-facing assets before they become incidents.

Powered by AppCheck, it replaces one-off annual assessments with continuous vulnerability scanning, prioritised findings and clearer remediation guidance.

Continuous Visibility Beyond Annual Testing

See how your exposure changes as code ships, infrastructure evolves and new vulnerabilities emerge.

Web, API and External Asset Coverage

Scan customer-facing applications, APIs, authentication surfaces and internet-facing assets from one service.

Reporting That Supports Faster Remediation

Give security and development teams prioritised findings, practical remediation guidance and clearer evidence of reduced risk.

Turn Continuous Security Testing Into Clear Priorities

Our external attack surface management service helps teams cut through scan noise and focus on the exposures most likely to affect live services, customer trust and compliance obligations.

The Problem with Point-in-Time Testing

Most organisations still rely on a single annual penetration test to judge their web security posture. That gives you a dated snapshot, not a live view of risk. In the months after a test, new releases go live, integrations expand, configurations change and fresh vulnerabilities are published. Attackers do not wait for the next scheduled review.

  • Why this matters:
  • Annual testing leaves long gaps between findings
  • Web application and API logic changes quickly
  • Compliance teams increasingly expect ongoing monitoring
  • Critical issues can sit undetected for months

Built to Protect What Matters

Our external attack surface management service does more than surface findings.

Powered by AppCheck, it helps teams identify and prioritise exploitable weaknesses across internet-facing applications, APIs and infrastructure before they become incidents.

  • Our External Attack Surface Management Service helps you:
  • Run continuous vulnerability scanning across agreed targets
  • Cover OWASP Top 10 issues, CVE-based exposures, misconfigurations and authentication flaws
  • Strengthen external asset visibility across customer-facing systems
  • Give security and development teams prioritised findings with remediation guidance
  • Access platform-level visibility, scheduling and reporting
A Strong Fit for Modern Vulnerability Management

For organisations that need more than a basic network vulnerability scanner, SurfacePulse adds web application and API vulnerability scanning alongside broader internet-facing visibility. That makes it easier to manage risk across the areas attackers are most likely to probe first.

  • Who SurfaceOur External Attack Surface Management Service is for:
  • SME to mid-market organisations running customer-facing web applications or APIs
  • Regulated sectors such as financial services, healthcare, e-commerce and SaaS
  • Development teams shipping frequent releases without repeat security testing
  • Security and compliance leaders needing evidence of continuous monitoring

Decision-Ready Exposure Management
Decision-Ready Exposure Management

Security teams do not need more dashboards. They need better prioritisation. SurfacePulse combines vulnerability data with asset criticality and attacker context so teams spend less time triaging noise and more time reducing real risk.

Risk Visibility That Reflects Reality

Focus on the assets attackers are most likely to target, not just the ones with the most findings.

Remediation Driven by Attack Paths

Direct effort toward vulnerabilities that enable compromise, movement and escalation.

Reporting That Shows Real Risk Reduction

Track progress based on meaningful risk reduction, not just vulnerability counts.

Exposure Visibility That Drives Action

Security teams need more than data. They need clear direction. Exposure Compass helps organisations prioritise remediation effort, reduce noise and focus on the exposures that matter most.
