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 LLC 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.
Every engagement is approached with an attacker's mindset and delivered with defender-focused outcomes. Available for remote and on-site engagements — nationwide.
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.
Mark conducted an internal penetration test that uncovered multiple high-severity findings our internal team had completely missed. What set him apart wasn't just the depth of the technical work — it was the way he communicated every finding. The final report was something I could walk into a board meeting with and actually use. He found privilege escalation paths through misconfigured service accounts we'd had in production for years. Clear methodology, exceptional documentation, and he stayed engaged through our remediation cycle. I wouldn't hesitate to bring him back for our next assessment.
We've engaged Mark across multiple assessment types and the quality has been consistent every time. On our most recent red team engagement, he demonstrated a full attack chain from initial phishing foothold to domain compromise — with detections bypassed at every stage. That's exactly the kind of adversarial pressure that tells you where your real gaps are. The debrief was thorough, the report was actionable, and Mark was available for follow-up questions through the entire remediation window. This is what a professional engagement looks like.
We think like adversaries because we are adversaries — certified, practiced, and battle-tested across real enterprise environments. Book a scoping call and let's find your gaps before someone else does.
