Compliance & Documentation
Our services are structured, auditable, and professionally managed to meet the expectations of critical-infrastructure operators and public entities.
Who We Are & What Sets Us Apart
Lioncrest Security, a division of Mance Consulting, was purpose-built to deliver exceptional corporate security and investigative services in environments where experience and judgment matter most. Our foundation is real-world law-enforcement experience, supported by disciplined operations and a commitment to professionalism at every level.
Our teams are composed exclusively of highly trained off-duty and retired law-enforcement officers who understand how to assess risk, deter threats, and respond effectively when seconds matter. This allows us to operate independently and professionally, reflecting the standards expected by public-safety agencies and critical-infrastructure operators.
Professional Investigations Backed by Experience
In addition to protective services, Lioncrest Security provides professional investigative capabilities rooted in proven law-enforcement methodologies. From internal investigations and incident follow-ups to theft, fraud, and threat-related inquiries, our investigators deliver clear, defensible findings supported by thorough documentation and chain-of-custody best practices.
Experience That Delivers a Strategic Advantage
We bring proven experience protecting utilities, critical infrastructure, industrial operations, construction sites, and public-facing environments where safety, continuity, and accountability are non-negotiable. With deep local knowledge of Northern Indiana and the Chicagoland region, Lioncrest Security enhances deterrence, coordination, and effectiveness through familiarity with communities, law-enforcement partners, and regional response dynamics.
A Compliance-Driven Partner
Above all, Lioncrest Security operates as a compliance-driven, documented, and reliable partner. Our security and investigative services are structured, auditable, and professionally managed—ensuring consistency, transparency, and confidence for clients who demand the highest standard of protection and accountability.
