Keeping New Jersey

Safe with Professional Security Guards

About CSI

Capital Security Investigations (CSI) is a Family-owned, private security company that provides armed & unarmed security services throughout the state of New Jersey. CSI has over 50 years of combined leadership experience, including Law Enforcement, Corrections and Military Personnel.  Our principal business is traditional security guard services, incorporating advanced technology.  

We partner with clients from every industry, delivering a robust solution that is within budget.  It’s our mission to provide security services of the highest quality at affordable pricing and have a comprehensive list of security services to meet a wide range of client needs.

Our Security Services

Armed Security Guard Services

Our armed security guards are licensed, highly trained, and experienced in handling high-risk environments. This service is ideal for banks, corporate buildings and high-value sites.

Unarmed Security Guard Services

Need a visible deterrent without the use of weapons? Our unarmed security officers are perfect for retail, construction sites, hotels, offices, and events. Guards are trained in surveillance, access control, and incident response.

Virtual Live Security Monitoring

Want 24/7 protection without someone physically on-site? Our virtual security guard services offer live video monitoring by trained agents. It’s a smart, cost-effective way to guard your business or property around the clock.

Why Choose CSI Security?

Hiring a security guard company isn’t just about filling a post, it’s about trusting someone with your people, your property, and your peace of mind. At CSI Security, we take that responsibility seriously.

Here’s what sets us apart from other security companies in New Jersey:



Law Enforcement Experience You Can Trust

Our team is built on a foundation of real-world experience. Many of our security personnel are former police officers or come from law enforcement backgrounds. That means you’re getting more than a uniform, you’re getting proven professionals who know how to de-escalate, deter, and respond effectively in real-time situations.

Tailored Security for Every Client

No two locations or events are alike. That’s why we conduct a site-specific security survey before every assignment. We design a plan based on your needs. Every detail is built around your environment, from entry points to patrol coverage.

Reliable, Local Presence

We’re based in Totowa and well acquainted with Passaic, Bergen, Essex, and Morris counties. That local focus means faster response times and guards who understand the communities they serve.

Professionalism That Reflects Well on You

Whether posted at a hotel, patrolling a parking garage, or securing a retail space, our guards are trained to represent your business professionally. They show up on time, stay alert, and treat your staff and customers with respect.

Flexible and Responsive Service

Need last-minute coverage or changes to your schedule? Our team is committed to meeting your needs quickly and reliably.
