Scan vs. Pentest

A scanner searches.
An ethical hacker thinks.

A vulnerability scan and a penetration test are not just two different depths of security testing. They are fundamentally different approaches with different logic, different outputs, and different purposes.

Vulnerability Scan Automated tool

Logic: match against a list

The scanner checks software versions and open ports — then compares them against a CVE database. It answers: "You're running Apache 2.4.51? There's a CVE-2021-41773 for that." Nothing more, nothing less.

What the scanner sees
Apache/2.4.51 — CVE-2021-41773 HIGH
OpenSSH 7.9 — outdated version MEDIUM
TLS 1.0 enabled MEDIUM
Missing X-Frame-Options header LOW
14 more findings...

⚠ The scanner doesn't know if Apache is reachable from the internet. It doesn't know if the CVE is actually exploitable. It has no idea what's behind the login page.

  • Fast — results within hours
  • Affordable — or free like this tool
  • Great for regular automated hygiene checks
  • Contains false positives — hard to tell what's a real risk
  • Blind to anything not in the CVE database
  • Not sufficient for NIS2, DORA or ISO 27001
Penetration Test Ethical hacker

Logic: thinks like an attacker

An ethical hacker has no checklist. They have a goal — get where they shouldn't. They chain vulnerabilities, study context, test what happens after login, and trace the path a real attacker would take first.

What the hacker finds on top
Apache only accessible internally — CVE not exploitable
Login form: admin/admin works CRITICAL
After login: full access to customer database
IDOR: changing ID in URL exposes other users' orders CRITICAL
These findings a scanner will never find...

✓ Every finding includes a PoC — proof the vulnerability is real. Zero false positives.

  • Verifies real exploitability — zero false positives
  • Uncovers logic flaws, auth bypasses and exploit chains
  • Report with prioritized, actionable recommendations
  • Meets NIS2, DORA, ISO 27001, PCI DSS requirements
  • Retest after remediation included

When to use which? A vulnerability scan is great for regular hygiene — run it monthly and track what changes. A penetration test is what you need when you truly want to know whether an attacker can get in — and how.

Guide

How to run a vulnerability scan?

01

Enter a domain or IP address

Enter a domain (www.example.com) or an IP address. A domain name is preferred — a single IP may host multiple applications.

02

Enter your email for the report

You'll receive an automated report with finding severity ratings (Critical / High / Medium / Low) delivered to your inbox.

03

Launch and monitor progress

OpenVAS scans from IP 178.238.36.101. Progress is visible in real time. You can pause the scan — a link to the progress view is sent by email.

04

Receive the report by email

Once the scan completes, the report is delivered automatically and can also be downloaded directly from the page. Note — reports may contain false positives and are intended for security engineers and system administrators.

Online tool

Run a vulnerability scan

Our application launches the OpenVAS security scanner in the background, checking your application or server against dozens of attack types and vulnerabilities. The scan runs from IP address 178.238.36.101.

Once complete, you'll receive an automated report with an overview of identified security gaps, their severity ratings and descriptions. The report is intended for security engineers and system administrators.

Warning

Only scan systems you own or have explicit permission to test. The scan may affect the availability of the target application.
