More than a security firm. SENTRYSIX is a next-generational full-spectrum mission support, security and intelligence operations platform — operational support, physical security, cyber defense, and protective operations — tailored to your mission and held under 24/7 overwatch from our SOC. With post-quantum cryptographic network infrastructure, and next-gen technology integrations, we earn the watch by securing what matters most today, and engineering what’s next.
SENTRYSIX is a next-generation security and intelligence operations company headquartered in Austin, Texas. We provide integrated protection to commercial, federal, and high-net-worth clients across Texas and Montana. As a veteran-founded SDVOSB and VOSB-certified company, we offer armed protective services, executive protection, secure communications, and intelligence operations through a 24/7 Security Operations Center. Our clients benefit from effective oversight, ensuring they never face a single point of failure between threat and response.
Our mission is to safeguard what matters by uniting people, technology, and intelligence under one command. For commercial and high-net-worth clients, we deliver premium armed protection and security operations that traditional firms cannot match. We are committed to securing today while engineering the future, including post-quantum cryptographic infrastructure and integrated cyber defense capabilities to extend operational security.
For federal agencies and prime contractors, we maintain a 3,800+ active cleared personnel database with vertical coverage across aerospace, space, cyber, homeland security, intelligence, public safety, and healthcare, available for mission-specific deployment.
SENTRYSIX provided military and law enforcement veterans to deliver premium armed and unarmed security services to commercial, residential, critical infrastructure, federal and high-net-worth clients across Texas to Montana — coordinated through a 24/7 Security Operations Center that supervises every officer on every shift. Our licensed armed security officers protect HOA communities, industrial sites, healthcare facilities, and executive residences with body-worn camera documentation and a clean nine-year operational record. Our unarmed security officers deliver professional access control, and observation-and-report services where uniformed presence is the right fit but armed authority is not required. Every SENTRYSIX officer — armed or unarmed — operates under continuous SOC oversight: real-time supervision, evidence retention, and immediate dispatched response coordination.
SENTRYSIX delivers 24/7 remote video monitoring for commercial properties, critical infrastructure, construction sites, and high-net-worth estates in Texas, Montana and across the United States — coordinated through our Security Operations Center with armed response on standby. Live operators verify alarm events, detect threats in real time, and dispatch licensed armed officers or law enforcement when the situation requires. Camera-only systems don’t stop incidents; SOC-coordinated video monitoring with verified response does.
At SENTRYSIX, you don’t just take a job; you join an elite team dedicated to the highest standards of safety and professional integrity.
