DTNK Shield is your partner in rethinking security assessments—streamlined, risk-driven, and built for real-world impact.
DTNK Shield was built to solve the GRC challenges that others overlook.
Who We Are
DTNK Shield is a cybersecurity consulting firm led by a former Accenture executive with 20+ years of experience delivering high-impact assessments across healthcare, government, and regulated industries.
We specialize in cybersecurity maturity, compliance, and risk governance. Our founder has led over 100 projects involving:
-
NIST CSF & CIS assessments
-
HIPAA Security Rule evaluations
-
NIST 800-53, CMMC, and FISMA alignment
Our mission: simplify compliance, strengthen security, and deliver results with speed and precision.
What We Solve
We eliminate GRC inefficiencies that drain time and resources — from manual evidence collection and siloed frameworks to audit fatigue and misaligned controls.
DTNK Shield replaces complexity with clarity through a unified, automated approach that reduces overhead and strengthens security posture with real-time visibility across systems, processes, and teams.
How We Work
We follow a risk-first, outcome-driven security assessment model that flips the traditional compliance mindset.
We begin by understanding how your departments operate in support of your mission — including the key processes, data, and systems they depend on.
Rather than assessing controls in isolation, we measure how effectively they mitigate real business risks.
By tying controls directly to threats, operational impact, and enterprise risk, we help you quantify exposure and prioritize remediation based on what truly matters.
Why Clients Choose Us
Our experience — gained while leading cybersecurity initiatives at firms like Accenture and Grant Thornton — includes designing, implementing, and refining security controls across Fortune 100 and federal environments. We understand what works under pressure and how to deliver practical, lasting results.
From security architecture to enterprise governance, we've supported both technical implementations and strategic oversight.
Over the past two decades, our expertise has contributed to:
100+ cybersecurity assessments across healthcare, finance, and public sector
Over $1B in protected digital assets
90%+ audit success rates for pre-certification readiness
6- to 8-week average project delivery
Our work is hands-on, practical, and built around what actually works — not just what looks good in a report.
