Head of Security partners with Chicago PI Services Group, a licensed Illinois private investigation firm, to deliver professional investigation, surveillance, fraud, process serving, and TSCM bug sweep services for clients across Chicago and the northwest suburbs.
Head of Security LLC is a security risk management firm, not a private investigation agency. When clients need licensed investigation work, process serving, or TSCM bug sweeps, we coordinate directly with Chicago PI Services Group, a licensed Illinois private investigation firm based in Arlington Heights.
This is a long-standing partner relationship built on operational trust. Our clients get vetted, licensed investigation services from a firm we know, while continuing to work through their existing Head of Security engagement when that makes sense. One point of coordination, licensed expertise behind it.
Chicago PI Services Group specializes in uncovering fraud, investigating infidelity, detecting electronic bugs, and providing professional process serving across Chicago and the northwest suburbs. Their team operates out of Arlington Heights and holds an active Illinois Private Detective Agency license.
Chicago PI Services Group provides the full range of licensed investigative services. Every engagement is handled directly by their team under their Illinois agency license.
Our clients can engage Chicago PI Services Group directly or coordinate through Head of Security. Many clients choose the coordination route when an investigation is part of a broader security engagement.
Private investigation is a regulated profession in Illinois. Doing it properly requires state licensure, legal compliance, and experience that sits outside the risk management and protective services focus of Head of Security. Rather than cut corners or act outside our lane, we partner with professionals who do this work every day.
Chicago PI Services Group holds an active Illinois Private Detective Agency license and operates under the regulatory framework for investigations in the state.
Infidelity investigation, TSCM, surveillance, and process serving all require specialized tradecraft that their team runs every week. We do not pretend to be generalists.
When an investigation connects to executive protection, threat risk assessment, or workplace violence prevention, we coordinate the handoff so nothing falls between the cracks.
Clients who prefer to engage Chicago PI Services Group directly without going through Head of Security can do so anytime. The partnership is a convenience, not a gate.
No. Head of Security LLC is a security risk management and protective services firm. We do not hold a private detective agency license and do not perform licensed private investigation work directly. For clients who need investigation, surveillance, TSCM, or process serving, we coordinate with our trusted partner Chicago PI Services Group, which is a licensed Illinois private detective agency.
Investigations require specialized expertise, state licensure, and legally compliant methodology. Chicago PI Services Group holds an active Illinois agency license (#117.001738) and has a strong track record in surveillance, fraud, infidelity, TSCM, and process serving. Rather than stretch our capabilities outside our core focus, we partner with a firm that does this work at a high standard every day.
Yes. Clients are welcome to contact Chicago PI Services Group directly at (847) 777-0266 or through their website at chicagopiservices.com. The partnership is for coordination convenience. It is not a gate or a referral fee arrangement. If your need is purely investigative and unrelated to a broader security program, going directly to them is often the faster path.
Coordination through Head of Security makes sense when an investigation is part of a broader security engagement. Examples include a TSCM sweep that accompanies executive protection, a background investigation that supports a workplace violence threat assessment, or surveillance that connects to a corporate security concern. In those cases, having one coordination point keeps findings integrated into your overall program.
TSCM stands for Technical Surveillance Counter Measures. It is the professional detection of hidden cameras, listening devices, GPS trackers, and other unauthorized electronic surveillance. Common situations include suspected corporate espionage, sensitive meeting spaces, executive residences, divorce and family law matters, and environments where privacy has been compromised. Chicago PI Services Group operates a professional TSCM practice as part of their core service set.
Yes. Chicago PI Services Group operates under strict confidentiality and client privilege standards appropriate to a licensed Illinois investigation agency. Information shared in connection with an investigation is not disclosed to third parties except as required by law or agreed with the client in advance. The same confidentiality standard applies when coordination is routed through Head of Security.
Start with a consultation through Head of Security or contact Chicago PI Services Group directly. Either way, you get licensed, professional investigation work handled the right way.
