Our Team


Built Different. Led With Purpose​
At Arguz Security, we don’t just secure assets, we protect your purpose.
We are a mission-driven force of professionals, bound by integrity, discipline, and a commitment to protecting lives, assets, and communities.
​
Founded by and led by leaders who don't just checks on a post, but ones who actually works the post. The one's that led from the front, and built this company from the ground up, not for just profit, but for purpose, Arguz challenges everything the public thinks it knows about private security.
​
We don’t just show up. We stand up, for our clients, our communities, and each other.
​
Who We Are
Our leadership is battle-tested, community-rooted, and unapologetically committed to doing things the right way, even when it’s not the easy way.
​
What Is an ASO: Arguz Security Officer
At Arguz Security, ASO stands for Arguz Security Officer, but it represents far more than a title.
​
Whether your rank is ASO, ASO1, ASO2, ASO3, ASO4, Corporal, Sergeant, First Sergeant, Lieutenant, Captain, Director, or CEO, we are all ASOs.
​
Every role, from the front line to the command staff, carries the same responsibility: to uphold professionalism, integrity, and accountability under the Arguz name.
That shared identity is what makes us different, it’s what makes us Arguz.
​
Our Team Includes:
-
Veteran professionals with backgrounds in law enforcement, first responders, and military.
-
State certified private security officers
-
Certified Classroom & Firearm Instructors
-
Proactive Site Supervisors
-
Executive protection officers and strategic thinkers
​
We don’t hand out uniforms, we build professionals.
Every Arguz team member is trained beyond the basics, prepared for real-world risks and real responsibility.
​
The Arguz Culture
At Arguz Security, culture isn’t a slogan, it’s a system.
One built on:
-
Accountability – We own every post, every shift, every mission.
-
Growth – We invest in mentorship, leadership training, and career development.
-
Standards – Our uniforms are sharp. Our reports are detailed. Our presence is professional.
-
​
We’re not just building a company, We’re building a legacy.
​
Our Motto: “Treat People Right.”
“The Arguz Standard — Do it Right. Treat ’em Right.”
This isn’t a tagline, it’s a principle.
It governs how we lead, how we serve, and how we protect.
We treat our clients, officers, and communities with dignity and respect: regardless of contract size, location, or challenge.
Every decision is filtered through one question: Are we doing it right and right by people?
Because security isn’t personal, It’s our business.
And Arguz Security is here to protect what matters.
