External Attack Surface Management (EASM)

See your organization the way attackers do — and secure it before they strike.

HALOCK’s External Attack Surface Management (EASM) service provides continuous discovery, exploit validation, and risk-based prioritization to keep you ahead of threats.

Your organization’s external-facing assets are the first line of exposure to attackers. But many remain unknown, unmanaged, or outdated. With expanding IT ecosystems, cloud adoption, and shadow IT, your attack surface grows daily — and traditional scans or point-in-time penetration tests aren’t enough. What is attack surface management – why does it matter?

Why External Attack Surface Management?

Attackers target what’s visible. Without visibility and validation, organizations struggle to:

  • Identify all external assets, including shadow IT
  • Reduce alert fatigue from noisy or inaccurate scan results
  • Prioritize which vulnerabilities to fix first
  • Demonstrate to regulators and auditors that external risks are managed
  • Communicate external risk posture to executives and stakeholders

EASM solves these challenges by continuously identifying assets, validating real-world exploitability, and helping prioritize remediation where it matters most.

What does HALOCK's EASM Services resolve?

  • Shadow IT – Discover unknown assets your teams didn't register
  • Cloud Risk – Monitor SaaS, cloud buckets, and misconfigured environments
  • Compliance Pressure – Demonstrate continuous risk management
  • Limited Resources – Focus efforts on vulnerabilities that matter most
  • Executive Reporting – Translate findings into business risk insights

HALOCK's EASM Delivery Process

Our approach goes beyond scanning to deliver actionable results:

  • Discovery – Continuous scanning of domains, IP ranges, and assets using DNS, OSINT, SSL, redirects, and more
  • Asset Management – Categorization of external assets such as cloud buckets, admin portals, and development environments
  • Scanning – Active scanning with advanced exploitation attempts (SQL injection, OS command injection, and more)
  • Validation – Evidence-driven validation to eliminate false positives
  • Prioritization – Context-aware scoring that considers exploitability, asset sensitivity, and business impact
  • Action – Playbooks and integrations support remediation workflows

How EASM Stands Apart

Vulnerability Scanning

  • Limitations: High false positives, no exploit validation, lacks business context
  • EASM Advantage: Evidence-driven, contextual, and prioritized results

Automated Penetration Testing

  • Limitations: Assumes breach, may disrupt systems, limited scope
  • EASM Advantage: Continuous, non-disruptive validation of exposures

Manual Penetration Testing

  • Limitations: One-time effort, costly, limited sampling, requires whitelisting
  • EASM Advantage: Continuous monitoring, scalable coverage, validated remediation

Engagement Options

HALOCK offers flexible EASM services to fit your needs:

  • Baseline Assessment – One-time scan with prioritized findings
  • Continuous Managed Service – Ongoing monitoring with validated exposures and reporting
  • Resell Options – Weekly or on-demand scanning at scale

**Pricing is based on the number of external assets such as domains, IP ranges, or systems. Packages scale for SMBs, mid-market, and enterprise organizations.

If you're looking to strengthen your cloud security strategy, this is where it starts.
