Red Obsidian Security

Most security companies won't even give you a price without scheduling a sales call.

We did the opposite.

We built an online estimator for Sioux Falls businesses. Pick what you need — mobile patrol, stationary guards, lockup service at close of business — build your weekly schedule, see your cost. Email it to yourself. No pitch, no follow-up call unless you want one.

Veteran-owned. Based right here in Sioux Falls. Written reports after every visit. And we take check or card — not just checks.

We turned down a contract last week.

The property manager wanted a warm body in a uniform standing by the door. That's it. No patrol requirements. No reporting. No accountability. Just a person. Breathing. Present.

We said no.

Red Obsidian Security doesn't fill posts. We protect properties. There's a difference — and if you've ever had a security guard who spent the shift on their phone, you already know it.

We'd rather protect 10 properties the right way than 50 the wrong way. That means we're selective. It means we say no sometimes. And it means when we say yes to your property, we mean it.

We're not for everyone. And we're okay with that.

Why "Red Obsidian"?

Obsidian is volcanic glass — formed under extreme pressure, razor sharp, and virtually indestructible. It was used as a weapon and a tool for thousands of years because of its strength and precision.

That's the standard we hold ourselves to. Military-trained. Disciplined. Sharp.

Red Obsidian Security was founded on the values learned through military service: integrity, vigilance, accountability, and an unwavering commitment to protecting others.

We brought those values home to Sioux Falls, and we bring them to every client, every shift, every call.

🔐 Quick Security Tip from Red Obsidian:

80% of break-ins happen through unlocked doors and windows. Not picked locks. Not smashed glass. Unlocked entry points.

Before you leave tonight, walk your property and check every door and window. It takes 2 minutes and it's the single most effective thing you can do to protect your home or business.

Need a professional security assessment? We test facilities for vulnerabilities before the bad guys do. That's what our pe*******on testing service is built for.
