Deep Infrastructure Penetration Testing
CyberAlpha's Internal & External Infrastructure Testing simulates real-world adversaries targeting your perimeter routers, firewalls, VPN concentrators, internal servers, and Active Directory environment. Our certified testers combine manual exploitation with curated automation to find vulnerabilities automated scanners miss.
From externally reachable services to lateral movement paths, privilege escalation chains, and Kerberos attacks, we expose the gaps that allow attackers to pivot from a single foothold to full domain compromise.
Every engagement concludes with a risk-ranked report, reproducible proof-of-concept steps, and a remediation roadmap aligned with CIS, NIST, and PCI DSS control frameworks.
Schedule a ConsultationUnpatched Servers
Legacy CVEs on exposed infrastructure remain the #1 initial access vector used by ransomware operators.
Misconfigured Firewalls
Permissive ACLs, exposed management interfaces, and flat network segments give attackers room to roam.
Active Directory Weaknesses
Kerberoastable service accounts, ACL abuse paths, and stale admin credentials lead directly to domain compromise.
Weak Credential Hygiene
Password reuse, LLMNR poisoning, and NTLM relay attacks expose privileged accounts in minutes.
The Hidden Risks in Your Network Estate
Unpatched Servers
Legacy CVEs on exposed infrastructure remain the #1 initial access vector used by ransomware operators.
Misconfigured Firewalls
Permissive ACLs, exposed management interfaces, and flat network segments give attackers room to roam.
Active Directory Weaknesses
Kerberoastable service accounts, ACL abuse paths, and stale admin credentials lead directly to domain compromise.
Weak Credential Hygiene
Password reuse, LLMNR poisoning, and NTLM relay attacks expose privileged accounts in minutes.
Lack of Segmentation
Flat networks let one compromised workstation expose the entire business, including OT and backup systems.
Detection Gaps
Many organizations cannot detect the noisy enumeration and lateral movement typical of post-exploitation activity.
End-to-End Network Penetration Testing
Manual, adversarial testing of every layer of your infrastructure, from the public internet to the domain controller.
Measurable Security Outcomes
Validated Attack Surface
Confirm exactly which services are exposed, which are exploitable, and which are safe to ignore.
Domain Compromise Defense
Eliminate the AD misconfigurations that let a single phish turn into enterprise-wide ransomware.
Compliance Evidence
Satisfy PCI DSS 11.3, ISO 27001, SOC 2, and HIPAA requirements for regular penetration testing.
Prioritized Remediation
Risk-ranked findings with business-impact context so engineering teams fix the right things first.
Detection Tuning Input
Detailed TTP evidence enables your SOC to tune alerts and close visibility gaps identified during testing.
Executive-Ready Reporting
Clear, non-technical executive summaries backed by deeply technical appendices for engineers.
Vulnerabilities We Regularly Uncover
Unpatched CVEs
Missing patches for EternalBlue, PrintNightmare, Zerologon, Log4Shell, and similar high-impact CVEs.
Kerberoasting
Service accounts with SPNs and weak passwords, crackable offline to yield privileged credentials.
NTLM Relay
LLMNR, NBT-NS, and mDNS poisoning combined with NTLM relay to authenticate as other users.
Exposed Management
RDP, WinRM, SSH, SMB, or IPMI interfaces reachable from untrusted networks without MFA.
Flat Networks
No segmentation between user VLANs and server/OT environments, enabling trivial lateral movement.
Default & Weak Credentials
Out-of-the-box credentials on appliances, iDRAC/iLO, databases, and network gear.
Reports That Drive Action
Executive Summary
Board-ready narrative of business risk, overall posture rating, and strategic recommendations.
Technical Findings Report
CVSS-scored findings with reproducible steps, screenshots, and mapped MITRE ATT&CK techniques.
Attack Path Diagrams
Visual kill-chain graphs showing how an attacker moves from initial access to domain admin.
Remediation Roadmap
Prioritized fix list with effort estimates, quick wins, and strategic hardening recommendations.
Compliance Mapping
Findings cross-referenced to PCI DSS, ISO 27001, NIST 800-53, and CIS Controls v8.
Retest & Sign-Off
Complimentary retest of remediated findings with an attestation letter suitable for auditors.
A Proven Testing Methodology
Scoping & Rules of Engagement
Define in-scope assets, testing windows, escalation contacts, and communication protocols.
Reconnaissance & Enumeration
OSINT, DNS and subdomain enumeration, service fingerprinting, and attack surface mapping.
Vulnerability Identification
Combine authenticated and unauthenticated scanning with manual verification to eliminate false positives.
Exploitation & Post-Exploitation
Controlled exploitation, privilege escalation, lateral movement, and Active Directory attacks.
Reporting & Debrief
Risk-ranked report delivery, executive debrief, and Q&A sessions with technical stakeholders.
Remediation Retest
Validate fixes and issue a clean attestation letter once critical findings are closed.
The Partner for Serious Security Teams
OSCP, OSEP & CRTO Certified
