Active Directory & Identity Security Assessment
Active Directory security review covering privileged accounts, Kerberoasting/AS-REP attacks, ACL and GPO misconfigurations, trusts, and BloodHound attack path mapping to identify domain compromise risks.
Network Architecture Security Review
Network security assessment covering firewalls, segmentation, DMZ, VPN, wireless, and NAC, identifying architectural weaknesses enabling lateral movement and data exfiltration beyond control-level checks.

Procurement & Third-Party Management
Independent security audit and pen test evidence supporting third-party risk assessments beyond vendor self-attestation.
Security Audit Solutions We Can Design, Build & Deploy
Proven security audit solution patterns – purpose-engineered for the threat models, compliance requirements, and assurance standards of enterprise organisations.
External Infrastructure Penetration Test
Black-box or grey-box external penetration testing simulating real attacker behaviour, covering reconnaissance, exploitation, and access attempts, with evidence-backed findings and prioritised remediation guidance.
Internal Network Penetration Test
Assumed breach internal penetration testing simulating post-compromise attacker activity, including lateral movement, privilege escalation, and AD attack paths to expose high-impact internal security weaknesses.
Web Application Penetration Test
Manual web application security testing against OWASP Top 10 and business logic flaws, covering auth, injection, access control, and API security with PoC evidence and remediation guidance.
Cloud Security Configuration Audit
Cloud security posture assessment across AWS, Azure, or GCP against CIS Benchmarks, covering IAM, network, storage, logging, and encryption with misconfiguration findings and remediation guidance.
Red Team Operation
Full-scope adversary simulation combining physical, social engineering, and technical attack chains targeting crown jewels to test detection, response, and containment beyond traditional penetration testing.
Active Directory Security Assessment
BloodHound-based Active Directory attack path analysis identifying privilege escalation routes and misconfigurations, delivering prioritised remediation steps to block ransomware-style domain compromise paths.
OT Security Audit
IEC 62443-aligned passive OT assessment covering asset discovery, vulnerabilities, OT/IT boundary security, and remote access controls, prioritised by operational impact rather than IT severity alone.
Application Source Code Review
SAST and manual code review of critical security paths including authentication, cryptography, input validation, and privilege management for pre-deployment assurance and M&A due diligence.
Our Process For Security Audit Delivery
A six-stage process – from audit scoping to findings remediation verification — with validated outputs at every stage.
Scoping & Rules of Engagement
Audit objective definition · threat model alignment · scope boundary documentation · asset inventory review · out-of-scope exclusion agreement · testing window definition · emergency contact and abort procedure · compliance framework alignment · methodology selection · rules of engagement documented and signed before testing begins
Reconnaissance & Intelligence Gathering
Passive OSINT — domain enumeration, employee profiling, technology fingerprinting, exposed credential identification, dark web exposure assessment · Active reconnaissance within agreed scope — network discovery, service enumeration, attack surface mapping · Reconnaissance findings informing prioritised testing methodology before active exploitation begins
Vulnerability Identification & Exploitation
Automated scanning supplemented by manual testing across agreed scope · Vulnerability exploitation with proof-of-concept evidence · Privilege escalation and lateral movement where in scope · Crown jewel access demonstration for red team engagements · BloodHound attack path mapping for AD assessments · Real-time client communication for critical findings requiring immediate attention
Post-Exploitation & Impact Assessment
Data access demonstration · persistence mechanism identification · detection evasion technique documentation · impact chain mapping from initial access to maximum achievable objective · Operational impact assessment for OT environments · Evidence capture for all exploited vulnerabilities · Scope boundary adherence validated throughout
Reporting & Findings Delivery
Executive summary — business risk narrative for board and management audience · Technical findings report — vulnerability detail, exploitation evidence, attack narrative, CVSS scoring, MITRE ATT&CK mapping, CWE classification, and remediation guidance · Risk-prioritised remediation roadmap · Compliance evidence packaging where applicable · Findings presentation and Q&A session with security and engineering stakeholders
Remediation Support & Verification Testing
Remediation guidance advisory during fix implementation · Technical question support for engineering teams · Remediation verification testing validating that identified vulnerabilities have been resolved rather than accepting developer attestation · Remediation verification report providing assurance evidence for compliance submission and board reporting

Security Audit FAQs
Have a question? We’re here to help.
What security audit services does Kernshell provide?
Kernshell delivers end-to-end security audits including penetration testing (internal/external), web & mobile app testing, cloud security audits (AWS/Azure/GCP), red teaming, OT/ICS audits, AD/identity reviews, network and code security reviews, physical security audits, and compliance-aligned audits (PCI-DSS, HIPAA, ISO 27001, SWIFT CSCF).
What is the difference between penetration testing, vulnerability assessment, and a red team engagement?
Vulnerability assessment identifies weaknesses. Penetration testing exploits vulnerabilities to prove impact. Red teaming simulates real attackers to test detection and response across the full attack chain.
How does Kernshell approach penetration testing methodology and what does the process involve?
Follows PTES/OWASP: scoping, reconnaissance, vulnerability discovery, controlled exploitation, post-exploitation, and reporting with evidence, impact analysis, and remediation guidance. Heavy focus on manual testing for real-world attack paths.
How does Kernshell conduct OT and ICS security audits safely without disrupting industrial operations?
Uses passive-first, non-intrusive methods to avoid disrupting industrial systems. Active testing is only done in controlled environments or approved maintenance windows due to safety-critical risks.
What compliance frameworks require independent penetration testing and how does Kernshell satisfy those requirements?
Supports PCI-DSS, HIPAA, ISO 27001, SWIFT CSCF, and TIBER-EU requirements through structured penetration testing and audit-ready evidence aligned to each framework.
How does Kernshell handle responsible disclosure and critical finding notification during an active assessment?
Critical vulnerabilities are immediately reported during testing via agreed secure channels so clients can remediate quickly. All communication is encrypted and governed by rules of engagement.
How does Kernshell approach security audits for M&A technical due diligence?
Rapid (2–4 week) security assessment covering infrastructure, cloud, identity, applications, and risk posture, with findings mapped to both technical teams and board-level acquisition risk decisions.
