Network & Infrastructure Penetration Testing Services

We work directly with your Network Engineering and Infrastructure teams to define target IP subnets (CIDR blocks), external VPN gateways, remote branch offices, and Active Directory forests under bilateral NDA. We formally isolate critical industrial OT/SCADA systems to ensure complete operational safety.

Executing thorough network enumeration across all 65,535 TCP ports and common UDP services. Our analysts identify exposed administrative interfaces (SSH, RDP, IPMI), unpatched VPN firmware (Fortinet, Palo Alto, Cisco), legacy SMBv1 protocols, and misconfigured perimeter routers.

Simulating a compromised employee workstation or rogue contractor plugged into an internal Ethernet port. We deploy BloodHound to mathematically map the fastest attack paths to Domain Admin, execute Kerberoasting, AS-REP roasting, and exploit vulnerable Active Directory Certificate Services (AD CS).

We test whether your internal firewall rules and VLAN microsegmentation effectively contain an adversary. Can a user in Corporate HR pivot into the core banking database subnet, the AWS production VPC, or the SWIFT payment cluster? We safely demonstrate access to designated 'Crown Jewels'.

We conduct an interactive debrief with your sysadmins and IT leadership, presenting exact PowerShell hardening scripts, GPO templates, and Active Directory Tiering architectures. A complimentary 30-day retesting window certifies complete risk reduction.

How does BlueCiphr test Active Directory without locking out user accounts or crashing domain controllers?

We perform rigorous reconnaissance on your Active Directory fine-grained password policies and account lockout thresholds prior to any authentication testing. We utilize non-intrusive enumeration (BloodHound LDAP querying, Kerberoasting without password spraying, and offline hash cracking on our isolated GPU clusters) so production users never experience lockouts and domain controllers operate with zero performance impact.

Can testing be conducted remotely, or do you require an on-site presence?

Both models are fully supported. For remote internal network penetration testing, we either connect via an encrypted client-provisioned VPN or deploy a hardened, pre-configured BlueCiphr Jumpbox virtual appliance (OVF/AMI) onto your network. For high-security environments, financial institutions, or wireless network assessments, our certified CEH and PenTest+ engineers can deploy directly on-site at your corporate headquarters or data centers.

What happens if our network contains fragile legacy hardware or industrial OT systems?

During the Phase 1 kickoff, we establish an explicit exclusion boundary. All fragile legacy devices, healthcare telemetry, and SCADA/OT subnets are marked out-of-bounds for active probing. Instead, we evaluate their segmentation from the outside—proving whether an attacker on an enterprise corporate workstation could route packets into those sensitive segments, without touching the fragile systems themselves.

Why is internal penetration testing just as critical as external perimeter testing?

Over 80% of devastating ransomware attacks and enterprise breaches do not exploit direct perimeter zero-days; they begin with a single compromised employee laptop (phishing or drive-by malware). Once inside, attackers exploit flat internal network architectures, unsegmented Active Directory domains, and shared local administrator passwords to achieve full domain dominance in under 2 hours. Internal testing verifies your defense-in-depth and lateral containment capabilities.

Does your assessment test our Endpoint Detection and Response (EDR) and SOC monitoring?

Yes. While conducting network testing, our engineers document the exact timestamp of every reconnaissance scan, credential request, and privilege escalation attempt. During the debrief, we compare these timestamps against your EDR alerts (CrowdStrike, Defender, SentinelOne) and SOC SIEM logs to identify blind spots where alerts were either never generated or missed by analysts.
