Private & Residential Security

Privacy and discretion are critical when protecting residences, estates, executives, and high-profile individuals.

Marshall Agency can develop security plans based on the property’s layout, access points, schedule, anticipated visitors, and specific areas of concern.

Assignments may include controlled access, perimeter security, visible or discreet officer presence, event coverage, executive protection, and security coordination for arrivals and departures.

Our goal is straightforward: provide professional protection without unnecessarily disrupting the client’s home, business, or daily routine.

Armed & Unarmed Security Options

Different environments require different approaches.

Marshall Agency can provide armed or unarmed personnel according to the nature of the assignment, client requirements, and applicable regulations.

A visible security officer can provide a strong deterrent in some environments. Other situations call for a lower-profile approach that emphasizes discretion and controlled observation.

We work with clients to determine an appropriate security posture before deployment.

Event security assignments may include:

  • Guest and credential verification
  • Entrance and exit monitoring

Experienced Security Professionals

Professional security depends on more than simply placing someone at an entrance.

Personnel must understand their responsibilities, communicate effectively, maintain situational awareness, document incidents, and respond professionally when circumstances change.

Marshall Agency emphasizes disciplined operations, professional conduct, and accountability. Our security services draw on law-enforcement, military, and private-security experience to provide clients with dependable protection.
