Chicago security & intelligence

Protecting what matters most.
Begins with the people.

The LandMark Group provides security and intelligence for Chicago's property managers, corporate entities, private residences and executives. Every plan we build begins with the people it protects.

Our approach

Identify, quantify and mitigate vulnerabilities.

Whether it's a family home, a Class-A office property or a corporate headquarters, every engagement follows the same disciplined process.

Step 1

Identify

We assess the people, the property and the routines around them to find where you are exposed.

Step 2

Quantify

Each vulnerability is weighed by likelihood and impact, so you know which risks matter most.

Step 3

Mitigate

We assign the appropriate level of protection, from officers and monitoring to training and policy, then reassess.

Properties · Property managers & corporate entities

Security officers for high-end office properties.

Whether you manage the property or lease space in it, the lobby is the first impression and the first line of defense. Our officers are hired and trained to handle both.

  • Lobby

    Off-duty police officers

    Sworn, off-duty police officers offer a discreet but commanding presence in your lobby.

  • Patrol

    Mobile patrol

    Staffed by off-duty police officers, with regular check-ins at your property, response when requested and focused attention wherever a problem keeps recurring.

  • Response

    Incident response & reporting

    Officers respond, document and keep property management informed, with clear reports you can act on.

Private residences · Live monitoring

Most cameras record. Ours respond.

For private homes, LMG agents watch your cameras in real time and stop an intruder before anyone reaches your door. Watch how a response unfolds.

Fence jump detection

The moment someone goes over a wall or gate, the camera flags it and an agent is on the live feed.

After-hours motion detection

Motion in the yard after your set hours is treated as a priority event, not a notification you'll find in the morning.

Live voice-down

Our agent speaks directly to the intruder through the camera's speaker, and escalates to police when the situation calls for it.

Executives

Discreet protection for the people a company depends on.

For executives, their families and visiting principals, we combine close protection with the intelligence work that comes before it: knowing who is around you, what is being said about you, and where the risk actually is.
