Red Obsidian Security delivers professional physical security across Sioux Falls and the surrounding region. Mobile patrol, stationary guards, and event & temporary coverage — one veteran-owned firm, one phone number, one team that actually answers at 2 AM. We protect apartment complexes, mobile home parks, storage facilities, business parks, HOAs, construction sites, and one-off events with the same operating standard the Marine Corps drills into its officers.
Most security work falls into one of three operating modes. We do all three under one roof, with one phone number and one set of standards. Pick the model that fits your property — or talk to us and we'll tell you honestly which one you actually need.
Marked patrol vehicle visits your property on a randomized schedule. Officers conduct documented perimeter checks, log anomalies with timestamps and photos, and email you a digital report after every visit.
A dedicated officer posted at a fixed location for the duration of the assignment. Lobbies, gates, entry points, sensitive areas, after-hours office buildings — anywhere you need a continuous, visible, accountable presence.
Short-term assignments that need professional coverage without a long contract. Public and private events, construction-site overnight watches, executive protection details, and rapid-response deployments where you need bodies on the ground today.
We do not believe in surprise invoices, mystery scope creep, or "we'll call you back next week." Every engagement runs the same four-step playbook so you know exactly what you are buying before any money changes hands.
We come on-site, walk the property with you, ask the questions that actually matter (where have you had problems, what time of night do they happen, who is the after-hours point of contact), and we listen more than we talk. Initial consultations are always free.
You get a written estimate by email — usually same-day, often within an hour for mobile patrol. Every line item is broken out: visits per week, expected duration on site, lockup/unlock cycles if applicable, applicable volume discount. No "call us for pricing" games.
Once you accept, we onboard your property in our system: contact tree, gate codes, special instructions, hot zones, key drop locations. First patrol or guard shift is usually within 48 to 72 hours of contract signature for mobile patrol; 5 to 10 business days for stationary depending on staffing scope.
You get a digital report after every patrol visit and a shift log after every guard shift. We review trends with you on a cadence that fits the assignment — weekly for active sites, monthly for routine accounts. If routes need to change, they change. Quietly, no drama.
If your property has a perimeter, an entry point, or a window of vulnerability, we have a coverage model for it. Below are the property types and sectors we work with most often in the Sioux Falls region.
Random-route patrols, lockup/unlock of common areas, parking lot checks, and rapid response to noise or disturbance complaints. Tenants and management both see the marked vehicle.
The MHP coverage model is what we built our patrol pricing around. Long perimeters, multiple entry roads, after-hours quiet checks — we know the territory.
Gate-cycle checks, unit-row patrols, after-hours visibility. Critical for facilities without on-site managers and for tenants storing high-value contents.
Multi-tenant complexes, after-hours commercial buildings, medical and dental parks. Patrol or stationary, depending on tenant traffic and night-shift activity.
Common-area patrols, clubhouse and pool-area checks during off-hours, and visible deterrence on neighborhood streets when boards request additional coverage during incident clusters.
Overnight equipment and material protection, gate watch, theft deterrence on sites with copper, lumber, or tools on the ground. Both stationary watch and mobile patrol options.
Closing-shift presence, parking-lot escorts for staff, after-hours patrol for storefronts. Especially valuable around holidays and during inventory periods.
Weddings, fundraisers, corporate functions, private parties. Crowd visibility, access control, professional presence without being intrusive on the host's atmosphere.
The regional security market is dominated by old firms running older billing systems. We compete on the things that actually matter to property managers, business owners, and homeowners in 2026.
Founded and run by a United States Marine Corps veteran. Military precision is not a marketing line — it is the operating standard for every patrol, post, and assignment. The owner answers the phone, walks the property, and signs the report.
Visa, Mastercard, Amex, Discover — processed through Stripe. Same-day, secure, no awkward conversation. Most regional competitors still require checks. We accept cards because that is how customers actually pay in 2026. ACH and net-terms billing available for established commercial accounts.
Real human, real phone, twenty-four hours a day. No call trees. No "leave a message and we'll get back to you Monday." If you are dealing with an active incident at 2 AM in February, someone answers — and a vehicle is moving within minutes when needed.

Three core service types: mobile patrol (randomized vehicle routes for properties needing periodic checks), stationary security (dedicated posted personnel at a fixed location), and event or temporary security (short-term contracts for events, construction sites, and emergency deployments). Every assignment is run by trained personnel and backed by electronic incident reporting.
A marked Red Obsidian Security vehicle arrives at your property on a randomized schedule, the officer conducts a foot or vehicle perimeter check using documented checkpoints, anomalies are recorded with timestamped notes and photos, and a digital report is delivered to you after each visit. Visits can be scheduled from one per week to multiple times per night.
