Senior offensive security consultant specializing in Active Directory exploitation, red team operations, cloud identity, and adversary simulation.
Every engagement is scoped to your environment, your adversary, and your risk tolerance. No off-the-shelf reports. No checkbox pentests.
Simulate a threat actor with internal access. Identify lateral movement paths, privilege escalation opportunities, and critical asset exposure before a real attacker does.
Simulate internet-facing adversaries targeting your exposed infrastructure, web apps, VPN gateways, and cloud perimeter from the outside in.
Targeted phishing campaigns and pretexting exercises that test your human layer. Credential harvesting, payload delivery, and awareness gap analysis.
Deep identity-focused analysis. Privilege escalation paths, delegation misconfigs, GPO weaknesses, and ACL abuse chains mapped with BloodHound.
Certificate Services attack surface review covering ESC1–ESC16 misconfigurations, enrollment agent abuse, and NTLM relay vectors using Certipy.
Multi-phase adversary emulation across physical, digital, and human attack surfaces. C2 infrastructure, evasion, persistence, and lateral movement to crown jewels.
Structured attack simulations with real-time detection validation. Measure your SOC's MTTD, tune SIEM rules, and close gaps before attackers find them.
Custom detection rules built from attacker behavior observed during engagements. Delivered in SIGMA format compatible with Splunk, Elastic, and Sentinel.
Scenario-based exercises for security teams, leadership, and incident responders. Walk through real attack chains and test your response playbooks.
Validate your logging coverage, data quality, and detection logic. Identify gaps in visibility before they become blind spots during an active incident.
Cloud identity attack paths including service principal abuse, Conditional Access gaps, Azure RBAC misconfigurations, and hybrid identity escalation.
Evaluate attack paths that span on-prem AD and Entra ID. Lateral movement from domain to cloud and vice versa via ADFS, PTA, PHS misconfigurations.
Assess your cloud configuration against CIS Benchmarks and compliance frameworks. Identify misconfigurations, over-permissive policies, and exposure risk.
I'm Mark Wharton, founder of W-Logic Security and creator of the Ethical Hacker's Workshop Series. With over 7 years in offensive security, I specialize in Active Directory exploitation, red team operations, and cloud identity attacks.
I've conducted engagements across enterprise environments, built C2 infrastructure, and designed purple team exercises that measurably improve detection capabilities. Every engagement is approached with an attacker's mindset and delivered with defender-focused outcomes.
Available for remote and on-site engagements and assessments.
Purple team education for practitioners, defenders, and security leaders. Each episode covers the attack, the detection, and the business impact.
Real engagements. Real findings. Measurable outcomes.
Being a multi-engagement customer of Mark's penetration and red team services, I feel comfortable comparing his expertise to bigger firms I've engaged with. His methods of compromise are clever, finding glaring and well-hidden holes in our systems. The penetration test reports are detailed and provide clear explanations on how to resolve the issues that were found. He also goes above and beyond most penetration testers by explaining in detail with demonstrations on how certain methods worked in our systems. One of the best penetration testers I've had the pleasure of working with.
