Defend Systems

What Defend Systems does

Defend Systems is a private, Brentwood, Tennessee-based security training and consulting firm founded by Brink Fidler that delivers on-site, hands-on engagements nationwide to schools, corporations, healthcare systems, places of worship, live-event and touring crews, law enforcement agencies, and government entities. The company sells a portfolio of seven core service lines — Active Shooter Response Training, Emergency Operations Plans, Security Vulnerability Assessments, Tactical Response Training, Medical Training, Keynote Speaking, and Physical Security Consulting & Design — plus two newer add-on offerings (Home & Family Security Services and New Construction Security Consulting), all priced via custom quote on a multi-year, engagement-based professional services model. Its underlying technology is its people and curriculum: 270+ combined years of law enforcement and special operations experience, an instructor team including a Director of Training with military and LE backgrounds, and a proprietary curriculum continuously refined against data from real-world active shooter incidents. Distribution is direct field sales via website contact form and phone inquiries, supplemented by an earned-media and content engine (podcast, YouTube, blog, Instagram), referrals from associations such as the Tennessee Hospital Association and standards body PASS, and a partnership stack spanning hardware (ZeroEyes, NightLock, TacMed, Punch Rescue), investigations (Covert Results), and K9 (Nashville K9). At scale the firm reports 50,000+ individuals trained, 2,000+ engagements, 500+ organizations served, and 500+ five-star client reviews, with national brand recognition following the March 2023 Covenant School incident in which its training was credited with saving lives.

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Allied Universal: Allied Universal (formed via the G4S merger) is one of the largest security services firms globally, offering manned guarding, consulting, and training across corporate, education, and government clients. It competes with Defend Systems on enterprise security consulting and training at much greater scale and capital depth.
• Raptor Technologies: Raptor Technologies is a leading K-12 visitor management, emergency management, and school safety platform. It addresses some of the same use cases as Defend Systems (emergency operations plans, drills, reunification) and is increasingly bundling training content alongside its software.
• Navigate360: Navigate360 is a broad K-12 school safety platform offering safety management software, training, behavior threat assessment, and emergency preparedness tools. While not a pure-services firm, it overlaps with Defend Systems on emergency operations planning and active shooter preparedness content and benefits from scale advantages.

Direct peers

• SafePlans: SafePlans is an emergency operations planning and school safety platform focused on K-12 districts, combining emergency management plans with drills and training. It directly competes with Defend Systems' emergency operations planning and active shooter training offerings in the education vertical.
• ALERRT (Texas State University): ALERRT is the leading research-based civilian and law enforcement active attack response training program, operated out of Texas State University. It is a category-defining reference for active shooter training content and competes with Defend Systems for the same school, law enforcement, and community preparedness budgets.
• ALICE Training: ALICE Training is one of the most widely adopted active shooter preparedness programs in U.S. K-12 schools, businesses, and houses of worship. It competes head-to-head with Defend Systems on the same buyer segments (schools, corporate, faith-based) and on overlapping curricula (alert, lockdown, inform, counter, evacuate), making it the closest direct comparable.
• Center for Personal Protection and Safety: CPPS provides workplace violence prevention, active shooter response, and security training to corporate, healthcare, and government clients. It targets the same enterprise buyer and curriculum space as Defend Systems, including tabletop exercises and site assessments.

Emerging players

• CrisisGo: CrisisGo provides emergency response communication and incident management software for schools and workplaces. It overlaps with Defend Systems on emergency operations planning and reunification procedures, but with a tech-enabled delivery model that complements or competes with Defend Systems' manual consulting work.
• LiveSafe: LiveSafe is a campus and workplace safety communication and tip-reporting platform. It is comparable to Defend Systems because buyers (universities, corporations, healthcare) evaluate it alongside active shooter and emergency response training, and it represents the tech-enabled approach to safety that Defend Systems does not yet offer.

Others

• ZeroEyes: ZeroEyes is an AI-driven gun detection platform integrated with existing camera systems. Defend Systems already partners with and refers clients to ZeroEyes, and both companies serve the same K-12, higher ed, and commercial buyers—making ZeroEyes an adjacent technology partner and emerging category competitor.
