Dark Web & Exposure Check

What attackers already know about your company.

Enter your company domain. The check shows in less than a minute whether your employees’ access data is being traded underground, whether your domain appears in data breaches or on ransomware leak sites and which weaknesses are visible from the outside.

Free and without an account. You can see the score and findings immediately, and you can activate details and measures with your business address.

How it works

Three steps, no account.

Step 1

Enter domain

Enter your company domain or a business email address. Only the domain is used, no account, no software.

Step 2

Seven check areas in four stages

n'guard queries public Infostealer databases, breach catalogs, ransomware leak site monitoring and certificate logs, and directly checks email security, TLS, headers and open services.

Step 3

Read the result and unlock

Exposure score, classification and all findings appear immediately on the page. You activate the technical details and the three prioritized measures with an email address for your domain, and the result comes as an email at the same time.

What is being checked

Seven questions the check answers for your domain.

Are employee devices infected with info stealers?

Credentials for company systems stolen by malware and traded underground, including session cookies that can bypass MFA.

Source: Hudson Rock OSINT

Was the domain part of a known data breach?

Documented data leaks in which data from this domain was leaked, with the date and type of data affected.

Source: Have I Been Pwned

Was the company named on a ransomware leak site?

Matched against ongoing monitoring of the publication sites of active ransomware groups.

Source: ransomware.live

Can someone send emails on your behalf?

SPF and DMARC decide whether to reject fake senders, DKIM provides the signature. MTA-STS and DNSSEC secure transport and name resolution.

Source: Google Public DNS

Is the website properly encrypted and hardened?

Certificate expiry, outdated TLS versions, HTTPS redirects, security headers and visible software versions.

Are remote maintenance or databases exposed to the internet?

Spot check of RDP, SMB, Telnet, VNC, FTP and common database ports on the main address. These are exactly the services ransomware most often uses to get in.

How large is the visible attack surface?

All subdomains that appear in public certificate logs, indicating testing, admin, and remote access systems. In addition, the reputation of the domain on the Spamhaus block list.

In simple words

What is the Dark Web & Exposure Check?

The n'guard Dark Web & Exposure Check is a free tool for Swiss companies that compiles what attackers can already know about a company domain. It combines two perspectives: the underground perspective (compromised credentials from infostealer infections, known data breaches, mentions on ransomware leak sites) with the outside perspective (email security, encryption, open services, visible systems).

Unlike verification services for private individuals, it is not about individual email addresses, but about the company as a whole. The result is an exposure score from 0 to 100, findings in seven areas of severity and three prioritized measures. The check is aimed at management, IT managers and security officers of SMEs who need an initial, fact-based assessment before deciding on penetration tests or ongoing monitoring.

All checks run on the server side at n'guard. Only counts and severity levels are shown, not passwords or personal data from leaks. Score and findings are visible without providing data; You can activate the technical details and measures using an email address for the checked domain and receive the result as an email at the same time.

Limits of the check

The check uses only publicly available sources and shows what is visible from outside. It replaces neither a penetration test nor continuous monitoring of your systems, and says nothing about your internal network, endpoints or cloud configuration. A high score means “no publicly visible findings”, not “safe”.

FAQ

Answers on the dark web, leaks and the check.

How do I check whether my company’s data is on the dark web?
Enter your company domain, for example company.ch, in the check above. The check matches the domain against public infostealer databases, breach catalogues and ransomware leak site monitoring, and shows counts and severity levels directly on the page. No registration is needed.
What are infostealer logs and why are they so dangerous?
Infostealers are malicious programs that read passwords, session cookies and form data stored on an infected device from the browser. The collected data sets are sold in Telegram channels and on underground marketplaces. If they contain access data for company systems, attackers can log in directly and sometimes even bypass two-factor authentication using stolen session cookies. A single infected personal device belonging to an employee is enough.
What does the check cost, and what do I see without entering any details?
The check is free and requires no account. Score, rating and all findings appear immediately. You unlock the technical details of each finding and the three prioritised measures by having the result sent to an email address on the checked domain. Only these contact details are stored, never content from leaks.
May I check any domain?
The check only shows information that is publicly available and does not reveal passwords, personal data or leaked content. It is intended for your own domain or for domains for which you are responsible. Only people with an address for the checked domain will receive the result by email.
Which sources does the check use?
Only publicly available sources: Google Public DNS for DNS records, crt.sh for certificate transparency, the breach catalog from Have I Been Pwned, the Infostealer OSINT interface from Hudson Rock, the leak site monitoring from ransomware.live and the domain block list from Spamhaus. n'guard checks TLS, security headers and open services directly from its servers. n'guard does not collect its own underground data, but rather aggregates, evaluates and translates it into measures.
What does a low Exposure Score mean?
The score starts at 100 and decreases with each finding depending on the severity. Below 65 points there are concrete, externally visible attack options. Below 40 points are critical findings, such as compromised employee devices, mentions on ransomware leak sites or publicly accessible remote maintenance and database services. In both cases, an inspection by specialists is recommended.
What is the difference between this check and a penetration test?
The check is an automated outside view based on public data and takes under a minute. A penetration test is a manual, authorised attack simulation by specialists that actually exploits vulnerabilities, examines systems in depth and delivers concrete remediation steps. The check shows where a pentest should start.
From the snapshot to the ongoing view

A check shows today. A SOC sees tomorrow.

n'guard’s Managed SOC continuously monitors your systems, your domain and the underground, and responds before a finding becomes an incident.
