Our Framework
The 4D Protection Model
Every Corsair security program is built on four proven layers: Deter, Detect, Delay, and Defend. Together they create a comprehensive, overlapping shield that protects people and property at every stage of a threat.
The Four Layers
Deter. Detect. Delay. Defend.
Each layer is designed to work independently and together — so even if one is bypassed, the next is already in place.
Deter
Make the threat think twice.
Deterrence is the first and most cost-effective layer of security. Visible, uniformed officers — armed or unarmed — signal to potential threats that your location is protected. Corsair deploys licensed officers whose presence alone reduces the likelihood of an incident before it starts. We also advise on signage, lighting, and physical layout changes that reinforce the deterrent effect.
How Corsair Applies It
- ›Uniformed armed and unarmed security officers at entry points
- ›Visible patrol routes through high-traffic areas
- ›Security signage and access control indicators
- ›Coordination with local law enforcement for high-risk events
Detect
See the threat before it acts.
Detection means identifying a threat early — before it escalates. Corsair officers are trained in behavioral threat recognition, situational awareness, and pre-incident indicators. We also consult on surveillance systems, access control technology, and visitor screening procedures that give your team the information needed to act decisively.
How Corsair Applies It
- ›Behavioral threat recognition training for staff and officers
- ›Visitor screening and credentialing protocols
- ›Surveillance system placement consulting
- ›Incident reporting and pattern analysis
Delay
Buy time for response.
When a threat cannot be deterred or detected in time, delay measures slow its progression — creating critical seconds and minutes for evacuation, lockdown, or law enforcement arrival. Corsair builds delay into your security plan through physical barriers, controlled access points, lockdown procedures, and officer positioning that channels and slows a threat.
How Corsair Applies It
- ›Controlled entry and access point design consulting
- ›Lockdown and shelter-in-place procedure development
- ›Officer positioning to create response time buffers
- ›Emergency communication and alert system planning
Defend
Protect when it matters most.
Defense is the final layer — the trained, authorized response when all other measures have been exhausted. Corsair's armed officers are licensed under Texas DPS and trained in use-of-force protocols, active threat response, and tactical decision-making. We also deliver Armed First Responder and active threat training to your staff so your entire team is prepared to act.
How Corsair Applies It
- ›Armed security officers — Texas DPS licensed
- ›Active threat response and use-of-force training
- ›Armed First Responder (AFR) certification courses
- ›Coordination with law enforcement on response protocols
