Do you need access to our systems?

No. The assessment only uses publicly available information, just like an attacker would.

How long does it take?

Typically one to two business days, including the report.

Is this the same as a penetration test?

No. An exposure assessment identifies what is visible; a penetration test checks if those findings can be exploited.

What Does an Attacker See About Your Company From the Internet? An Overview of External Exposure

An external exposure assessment shows which services, subdomains, and data of your company are visible from the internet. Learn what we check and how to reduce risk.

German Vitali·17. oktober 2026·1 min branja·Cybersecurity

External attack surface assessment shows what an attacker sees when they look at your company from the internet: open services, forgotten subdomains, outdated VPN appliances, leaked email addresses, and breached passwords. Attackers collect this data automatically — which is why it is best that you know it first.

TL;DR — Key Highlights

Most attacks start with something publicly visible from the internet.
Common findings: open Remote Desktop Protocol (RDP), outdated VPNs, forgotten staging sites.
The assessment does not require access to your systems — it looks at them from an attacker's perspective.
It is a fast and cost-effective first step before a comprehensive security audit.

What We Check

Area	Example Finding
Open services	RDP, SMB, or admin interfaces accessible from the internet
VPN and Firewalls	Outdated software with known vulnerabilities
Subdomains	Forgotten staging sites or old e-commerce platforms
Email	Missing DMARC records that allow email spoofing in your name
Data Breaches	Corporate addresses found in known databases of stolen credentials
Certificates and Website	Expired certificates, outdated plugins

Why It Matters

Attackers do not choose targets by size but by opportunity. Automated tools — increasingly powered by AI — scan the entire internet daily searching for open services and known vulnerabilities. If your device is among them, you are a target, regardless of whether you are a company with 5 or 500 employees.

How to Reduce Exposure

Close services that do not need internet access (e.g., RDP).
Update VPN appliances and firewalls.
Remove forgotten subdomains and pages.
Configure SPF, DKIM, and DMARC.
Change passwords and enable MFA for accounts found in data breaches.
Repeat the assessment at least every six months.
