What every network pentest includes

  • External and internal network testing
  • Network segmentation validation
  • Active Directory attack path testing
  • Lateral movement and privilege escalation
  • Egress control testing
  • Detection validation when included in scope

What is network penetration testing?

Network penetration testing is a controlled assessment of external or internal infrastructure. Blaze tests exposed services, systems, Active Directory, credentials, segmentation, and trust relationships to identify exploitable weaknesses, trace realistic attack paths, and explain how to reduce the risk.

Why Blaze

Why choose Blaze for network penetration testing?

Get realistic attack-path testing, validated findings, and direct access to the experts doing the work.

Target

Active Directory focus

Identify practical Active Directory paths from an initial foothold to privileged access.

List Checks

Segmentation testing

Verify isolation across VLANs, zones, and trust boundaries through controlled lateral-movement testing.

Eye

Detection validation

When included, test whether controls detect relevant techniques and where visibility is missing.

Compliance

Network pentesting for compliance and beyond

Reports can map relevant findings to PCI DSS, SOC 2, and ISO 27001 requirements while staying focused on exploitable network risk.

External, internal, and wireless network testing

Choose the network scope that matches your infrastructure, threat model, and assurance requirements.

Globe

External network penetration testing

Assess firewalls, exposed services, VPNs, DNS, and other internet-facing infrastructure from an external attacker's perspective.

  • Firewall configuration
  • Exposed services
  • SSL/TLS security
  • DNS vulnerabilities
  • VPN security
Network

Internal network penetration testing

Simulate a compromised endpoint or insider against Active Directory, segmentation, credentials, and lateral-movement paths.

  • Active Directory
  • Network segmentation
  • Privilege escalation
  • Credential harvesting
  • Lateral movement
Wifi Signal

Wireless assessment

Assess wireless authentication, rogue access, guest isolation, and common enterprise Wi-Fi attack paths.

  • WPA/WPA2/WPA3 testing
  • Evil twin attacks
  • Rogue access points
  • Guest network isolation
  • Wireless IDS evasion

Network attack techniques we test

Coverage follows your systems, identities, trust boundaries, and agreed attack scenarios.

01

Service exploitation

Vulnerable network services and misconfigurations

02

Credential attacks

Password spraying, Kerberoasting, AS-REP roasting

03

Man-in-the-middle

ARP spoofing, LLMNR/NBT-NS poisoning

04

Privilege escalation

Local and domain privilege-escalation paths

05

Lateral movement

Pass-the-hash, token impersonation, RDP pivoting

06

Data exfiltration

Testing DLP controls and egress filtering

From beginning to the end of the project, the collaboration was really good and respectful and the delivery of the service was great.

Frequently asked questions

Answers about external and internal scope, Active Directory, access, timelines, pricing, and remediation.

Pricing depends on whether the scope is external, internal, wireless, or combined; the number of systems and locations; Active Directory complexity; access assumptions; and testing depth. Share the environment and objectives for a fixed scope and quote.
External testing targets internet-facing infrastructure. Internal testing starts from an agreed foothold and focuses on identity, segmentation, privilege escalation, and lateral movement.
Duration depends on host count, sites, access, and whether internal, external, wireless, or Active Directory testing is included. Blaze confirms the testing window during scoping.
Yes. Coverage can include credentials, permissions, delegation, service accounts, trust relationships, and practical routes to privileged access.
Yes, when included in scope. Blaze can record the techniques used, compare them with available telemetry, and identify visibility gaps.
Scanning identifies potential weaknesses. A network pentest manually validates exploitability, tests realistic attack paths, and explains practical risk.
Testing follows agreed systems, safety limits, and communication paths. Potentially disruptive actions require explicit approval.
Yes. Researchers can verify agreed fixes and document whether the original attack path has been closed.
