External Attack Surface Assessment
Free Vulnerability Assessment

See Your Exposure the Way Attackers Do

Our free assessment uses an external attack surface analysis — the same technique real threat actors use — to map every vulnerability visible from outside your network. No agents. No installs. No disruption to your business.

How it works

1

You share your domain or IP range

That's it. No credentials, no VPN access, no software to install. Just your organization's public-facing identifiers.

2

We scan from the outside in

Our platform enumerates your exposed assets — domains, subdomains, open ports, services, certificates, and cloud resources — exactly as an attacker would.

3

Risks are identified and scored

Each finding is mapped to known CVEs and attack techniques, then prioritized by exploitability and potential business impact.

4

You receive a clear, actionable report

A plain-language findings report with prioritized remediation steps — no jargon, no filler. Walk away knowing exactly what needs to be fixed first.

Zero-touch

Nothing to install. Nothing to configure. Nothing to remove.

Traditional vulnerability scans require installing agents on every endpoint, configuring network credentials, or granting internal access — creating delays, IT overhead, and potential new risk. Our external attack surface assessment requires none of that. It operates entirely from the outside, the same vantage point a cybercriminal has, which means you get an accurate picture of your real-world exposure without touching a single machine on your network.

Why an external assessment?

Results in hours, not weeks

No deployment phase means no waiting. Your assessment begins immediately and delivers findings the same day — not after a weeks-long onboarding process.

Fast Turnaround

The attacker's true perspective

Internal scans only show what's visible from inside. Our external assessment reveals exactly what a threat actor sees — forgotten assets, shadow IT, and exposed services you may not know exist.

Real-World View

Zero IT burden on your team

No agent deployments. No firewall rule changes. No internal network credentials handed over. Your IT staff don't need to be involved at all — freeing them to keep the business running.

No IT Overhead

No access, no risk

Granting internal access to a third party introduces its own security risk. Because we never touch your internal systems, there is no expanded attack surface, no credential exposure, and no supply-chain risk.

Zero New Risk

Uncovers assets you've forgotten about

Subdomains from old campaigns, cloud buckets left open, legacy login portals — external scanning surfaces the forgotten corners of your environment that internal tools never see because nobody configured them to look.

Shadow IT Discovery

Supports compliance requirements

Many frameworks — including SOC 2, HIPAA, and cyber insurance applications — require documented evidence of external vulnerability assessments. Our report gives you audit-ready proof of due diligence, instantly.

Understanding Vulnerability Scores
Know your risk — really

What a Vulnerability Score Actually Means

A vulnerability score isn't just a number — it's a calculated risk rating built from eight distinct factors. Understanding what goes into that score is the difference between prioritizing the right fixes and ignoring the ones that will get you breached.

CVSS v3 severity scale (0.0 – 10.0)

None 0.0
Low 0.1 – 3.9
Medium 4.0 – 6.9
High 7.0 – 8.9
Critical 9.0 – 10.0

Every vulnerability receives a score from 0.0 to 10.0 using the Common Vulnerability Scoring System (CVSS) — the global standard used by NIST, CISA, and security vendors worldwide.

Attack vector

How is the vulnerability reached?

Measures whether an attacker needs physical access, local network access, adjacent network access, or can exploit it remotely over the internet. Remote exploitability scores highest.

Network (remote) Adjacent Local Physical

Attack complexity

How hard is the exploit to execute?

Reflects whether the attack requires special conditions — timing, specific configurations, or additional steps — or can be reliably executed by any attacker on demand. Low complexity scores much higher.

Low (reliable) High (conditional)

Privileges required

What level of access does the attacker need first?

Determines whether an attacker needs no prior access, low-level user credentials, or administrator-level privileges to trigger the vulnerability. No privileges required scores highest.

None Low High

User interaction

Does a user have to do something?

Captures whether the attack requires a user to click a link, open a file, or visit a page — or whether the attacker can exploit it entirely without any human involvement. No interaction required scores highest.

None required Required

Scope

Can the attack spread beyond the vulnerable component?

A "changed" scope means a successful exploit can impact other systems, users, or components beyond the vulnerable one — for example, a compromised container breaking out to the host OS. Changed scope significantly increases the score.

Unchanged Changed

Confidentiality impact

Can sensitive data be read or stolen?

Measures whether an exploit allows an attacker to read protected data — from none at all, to partial access, to complete disclosure of all data on the affected system.

None Low High

Integrity impact

Can data be modified or tampered with?

Assesses whether an attacker could alter files, configurations, or data — from no modification possible, to limited changes, to complete control over what gets written to a system.

None Low High

Availability impact

Can the system or service be taken offline?

Evaluates whether a successful exploit could degrade or completely deny access to a service — the core driver behind ransomware and denial-of-service attacks that shut businesses down entirely.

None Low High

Real-world breaches don't only come from Critical-rated vulnerabilities

CVSS score distribution of vulnerabilities actively exploited in confirmed breaches — lower scores are weaponized far more often than most organizations expect

Low (0.1–3.9) — 9% Medium (4.0–6.9) — 31% High (7.0–8.9) — 38% Critical (9.0–10.0) — 22%
Distribution of exploited vulnerabilities by CVSS severity: Low 9%, Medium 31%, High 38%, Critical 22%.

Source: CISA Known Exploited Vulnerabilities (KEV) Catalog & Verizon DBIR analysis. Medium and High vulnerabilities together account for nearly 70% of actively exploited findings.

"It's only a Medium score — we don't need to fix it right now."

The reality

CVSS scores measure technical severity in isolation — not real-world risk to your specific environment. A Medium-scored vulnerability on an internet-facing login portal, combined with no multi-factor authentication, can be far more dangerous than a Critical score on an air-gapped internal server nobody can reach. Context is everything, and "medium" is not a synonym for "unimportant."

"We only have Low findings — we must be pretty secure."

The reality

Attackers routinely chain multiple Low and Medium vulnerabilities together in a single attack sequence — a technique called vulnerability chaining. Each step individually scores low, but combined they can lead to full administrative control of your network. A wall of "Low" findings is not a clean bill of health; it may be a roadmap attackers are already using.

"We patched all the Criticals — we're covered."

The reality

31% of confirmed breaches in recent years exploited vulnerabilities rated Medium or below. Focusing exclusively on Critical findings is a common and costly mistake. The CISA Known Exploited Vulnerabilities catalog includes hundreds of Medium and High findings that are actively weaponized in real attacks against businesses today.

"Our software vendor said it's low risk — so we won't patch it."

The reality

Vendors score vulnerabilities based on a generic deployment scenario — not your specific configuration. A vulnerability a vendor rates Low in a default setup could score significantly higher in your environment depending on how the software is exposed, what it connects to, and what data it can access. Always validate vendor scores against your actual attack surface.

"There's no public exploit for it, so it won't be used against us."

The reality

Private exploit code is bought and sold on dark-web forums long before it surfaces publicly. On average, exploit code for a new vulnerability appears within 15 days of disclosure. "No known public exploit" does not mean "safe to ignore" — it means the clock is ticking and your window to patch is closing fast.

"We're a small business — nobody is targeting us specifically."

The reality

Most attacks on small businesses are not targeted — they're automated. Bots continuously scan the entire internet for specific vulnerable software versions and misconfigurations. Your company size is irrelevant. If your systems have unpatched vulnerabilities, scanners will find them and flag your business as an easy target within hours of a new exploit being released.
