External Attack Surface Management
We look at your surface the way attackers do—same logic, mindset, and timing.EASMWe verify what’s exploitable before we escalate—so you get a short, evidence-backed list, not thousands of raw alerts. CTEM-aligned external monitoring, audit-ready proof, and security assurance that stand up to regulators and insurers, plus near real-time zero-day exploitability impact modeling that compresses impact assessment from days to minutes.
Why External Assurance Has to Be Defensible
Unmonitored or unverified surfaces create blind spots and proof gaps. We deliver continuous, audit-ready evidence so you can show what you found, when, and what you did.
External Exposure Blind Spots
Unmonitored internet-facing assets create silent risks and unaccounted attack paths—attackers find them first.
Verification Gaps
Findings without external proof don’t hold up to regulators, insurers, or post-incident reviews.
Assurance Over Time
Compliance and security both need continuous evidence of monitoring and drift—not one-off scans.
Discovery is easy; validation is the bottleneck. Many tools dump raw scanner output—but in real environments a large share of findings aren’t exploitable in context (auth, WAF, dead assets). We verify first, then escalate: a short, evidence-backed list instead of noise.
Complete EASM + Regulator Assurance
Attacker-grade discovery and evidence-grade visibility for security teams, compliance, regulators, and insurers.
Fusionstek is built for teams searching for an attack surface management tool, external attack surface discovery, or a cyber exposure management platform that also produces defensible evidence.
Attacker’s View: Logic, Mindset & Timing
We look at your applications and external surface the exact way attackers do—same discovery logic, prioritisation, and timing—so you see what they see, with proof.
Verification-First Findings
We only escalate what we can prove is exploitable—with proof artifacts and attack-path context. Less triage, faster remediation, stronger credibility with regulators and insurers.
Audit-Ready Reporting
Explainable, deterministic reports for security teams, regulators, and insurers.
Continuous Assurance
Daily refresh, drift detection, continuous security validation, and near real-time zero-day exploitability impact modeling to prove you stayed secure over time. Prove how long issues were exposed with impact assessment compressed from days to minutes.
One View of Your External Attack Surface
The Attack Surface dashboard gives you a single, evidence-backed view of what’s exposed—and what changed—so you can act and prove it.

Choose a completed scan and see everything we found: domains, subdomains, IPs, open ports, URLs, and API endpoints in one place. Health, coverage, confidence, and scope scores show you how thorough the run was—and drift events show exactly what appeared, changed, or disappeared since the last run.
That’s the same view your security team uses to prioritise risks and the same evidence you can point to for regulators and insurers: attacker-grade discovery, with verification and timelines built in.
- Full asset inventory per scan
- Health, coverage, confidence, scope
- Drift detection and change tracking
- Audit-ready evidence in one dashboard
See What We Offer
Three client-facing services built around attacker-mindset external assurance and defensible reporting.
External Attack Surface Assurance
Continuously discover, validate, and monitor internet-facing assets, services, and exposures with included cloud surface detection, third-party exposure visibility, threat correlation, and evidence-backed reporting.
Zero-Day & Emerging Threat Monitoring
Model near real-time exploitability impact as zero-day signals emerge, then alert with asset-specific context from baseline and refresh runs.
Brand & Domain Impersonation Protection
Monitor lookalike domains and impersonation candidates to catch abuse patterns and reduce external trust attacks.
Fusionstek combines external attack surface management, zero-day vulnerability monitoring, phishing domain monitoring, third-party risk monitoring, and cloud misconfiguration detection in one exposure management platform.
How It Works
Deterministic discovery, verification, and evidence—no guesswork.
Submit Scope
Provide domains and approved scope under your policy.
Discover & Map
We enumerate internet-facing assets and build a verified surface map.
Verify & Analyze
Findings are validated with evidence, not assumptions.
Deliver Evidence
Receive audit-ready reports and continuous assurance tracking.
