Network Penetration Testing
Are your exposed systems protected against real attackers?
Every server, firewall and service reachable from the internet is a door. A network penetration test checks each one the way an attacker would, and then asks what happens once they are inside.
We test both the external perimeter and, where agreed, the internal network: what an attacker could reach after one successful step, or what an insider could reach from the office.
What we test
External footprint: what is exposed, versions and banners, and misconfigured services
Access controls: firewall rules, open ports, weak or default credentials
Common misconfigurations: SMB, RDP, management interfaces and their known pitfalls
Internal testing: lateral movement, shared credentials and what a foothold unlocks
Segmentation: whether networks that should be separate actually are
How we test it
We agree the scope first: what to test, when, and what is off limits.
Testing combines manual work with automated tools and AI assisted analysis.
Every finding is verified by hand, with evidence captured for your team.
The weaknesses that matter
These are the kinds of findings this assessment is built to catch, each explained the way it would appear in your report.
MITRE ATT&CK T1190
Unpatched public-facing services
A known vulnerability in an internet-facing service lets an attacker run code on your server without touching a single password.
MITRE ATT&CK T1078
Stolen or reused credentials
Passwords reused from another breach, or accounts left open when staff leave. The attacker doesn't break in, they log in, and nothing looks unusual.
MITRE ATT&CK T1110
Brute-forceable remote access
Internet-facing remote access with no lockout and no second factor can be guessed at machine speed. A weak password falls within hours.
CWE-521
Default and guessable passwords
A router or appliance accepts default credentials from the internet, the digital equivalent of leaving the keys in the door.
MITRE ATT&CK T1021
Lateral movement
One compromised machine can reach systems it should never see, a single breach that becomes a whole-network problem.
MITRE ATT&CK T1040
Cleartext traffic
Passwords and data cross the internal network unencrypted, readable by anyone who can listen, including an attacker who already has one foothold.
