Network security assessment
See your network the way an attacker sees it.
External and internal network testing, with clear advice on what to close, patch or separate.
Why teams call us
Problems this solves
-
01
Services exposed by accident
Remote desktop, databases or admin panels reachable from the internet.
-
02
A flat internal network
One infected laptop can reach servers, backups and finance systems.
-
03
Old devices and firmware
Routers, firewalls and printers that have not been patched in years.
-
04
Remote access added in a hurry
VPNs and remote tools set up quickly and never reviewed.
Our approach
We test from outside, as an internet attacker would, and from inside, as a compromised device or insider would. The goal is to show which systems can be reached, which can be exploited, and how far an attacker could move.
Findings come with hardening steps for each device or service, and recommendations on segmentation so that one problem stays contained.
What is included
-
External testing
Internet-facing services, VPNs and remote access.
-
Internal testing
Lateral movement, Active Directory weaknesses and segmentation.
-
Wireless review
