Service Overview

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 Consultation

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.

Why It Matters

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.

Our Solutions

End-to-End Network Penetration Testing

Manual, adversarial testing of every layer of your infrastructure, from the public internet to the domain controller.

External Penetration Testing

Black-box assessment of internet-facing assets including VPNs, mail gateways, web portals, and edge devices.

Internal Penetration Testing

Assumed-breach simulation from a standard user or dropped-device position to test lateral movement.

Active Directory Assessment

Kerberoasting, ASREP, DCSync, ACL abuse, and privilege escalation path mapping with BloodHound.

Firewall & Segmentation Review

Rule-base analysis and segmentation testing to validate that trust boundaries actually hold.

Privileged Access Review

Evaluation of Tier-0 assets, bastion hosts, PAM deployment, and admin workflow hardening.

CVE Exploitation & PoC

Safe, controlled exploitation of known CVEs with reproducible PoC evidence for your remediation teams.

Key Benefits

Measurable Security Outcomes

01

Validated Attack Surface

Confirm exactly which services are exposed, which are exploitable, and which are safe to ignore.

02

Domain Compromise Defense

Eliminate the AD misconfigurations that let a single phish turn into enterprise-wide ransomware.

03

Compliance Evidence

Satisfy PCI DSS 11.3, ISO 27001, SOC 2, and HIPAA requirements for regular penetration testing.

04

Prioritized Remediation

Risk-ranked findings with business-impact context so engineering teams fix the right things first.

05

Detection Tuning Input

Detailed TTP evidence enables your SOC to tune alerts and close visibility gaps identified during testing.

06

Executive-Ready Reporting

Clear, non-technical executive summaries backed by deeply technical appendices for engineers.

Common Findings

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.

Deliverables

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.

Our Approach

A Proven Testing Methodology

01

Scoping & Rules of Engagement

Define in-scope assets, testing windows, escalation contacts, and communication protocols.

02

Reconnaissance & Enumeration

OSINT, DNS and subdomain enumeration, service fingerprinting, and attack surface mapping.

03

Vulnerability Identification

Combine authenticated and unauthenticated scanning with manual verification to eliminate false positives.

04

Exploitation & Post-Exploitation

Controlled exploitation, privilege escalation, lateral movement, and Active Directory attacks.

05

Reporting & Debrief

Risk-ranked report delivery, executive debrief, and Q&A sessions with technical stakeholders.

06

Remediation Retest

Validate fixes and issue a clean attestation letter once critical findings are closed.
