Network Penetration Testing
Validate your perimeter and internal attack surface with manual network penetration testing. Budget Security helps you uncover misconfigurations, weak segmentation, and exploitable services, without the overhead of traditional firms.
External network testing focuses on internet facing systems like VPN gateways, mail services, remote access, and exposed services. Internal testing simulates an attacker who already has a foothold, testing lateral movement, privilege escalation, and resilience against realistic intrusions.
Whether you need an external assessment for due diligence or an internal test to validate Zero Trust assumptions, you can scope targets, choose testing depth, and book online with clear pricing.
How we approach network pentesting
Testing combines structured manual analysis with supporting tooling to identify reachable services, misconfigurations, and exploitable weaknesses. Findings are validated to reduce false positives and help your team prioritize patching and architecture improvements.
Discovery & enumeration
Full TCP and targeted UDP sweeps, service versioning, DNS and certificate transparency review.
Exposure analysis
Default credentials, forgotten admin panels, unpatched edge devices, exposed management planes.
Active Directory
Kerberoasting, AS-REP roasting, delegation abuse, ACL path analysis to Domain Admin.
Lateral movement
Credential reuse, relay attacks, share enumeration, mapped paths from foothold to crown jewels.
Segmentation validation
Proof of whether the VLAN and firewall boundaries you documented actually hold.
Egress & detection
What leaves the network unnoticed, and which of our actions your tooling caught.
Example finding
This is the format a finding arrives in.
An example of the format. Every finding carries a rating, reproduction steps and remediation guidance.
Unconstrained delegation on PRINT-02
A legacy print server is configured for unconstrained Kerberos delegation. Coercing a Domain Controller to authenticate to it yields a TGT for the DC machine account.
Remediation
Remove unconstrained delegation, move to resource-based constrained delegation and add the DC accounts to Protected Users.
What is included
No upgrade tiers. The auditor-ready package is the standard package.
