Sentinel is a Dallas based marketplace connecting principals, executives, public figures and their families, with independently vetted Texas security firms. We don't provide protection. We curate the firms that do, and match you to the right one.
Principals filter the network by the protection they actually need. Every category below is delivered by independent, vetted firms on the platform, never by Sentinel.
Browse firms staffed with Texas DPS Level III & IV licensed officers for close protection, family movements and high risk travel across DFW and nationwide.
Match with firms offering boardroom security, C suite EP programs, facility hardening, event security and travel risk management for Dallas enterprises.
Find Level II licensed agents for residences, estates, family logistics and low profile escorts where visible firepower is not appropriate.
Sentinel extends beyond security firms. Principals can also request private aviation and armored transport from vetted partner providers, so the full movement is planned in one place instead of stitched across vendors.
Coordinate vetted Part 135 charter operators alongside your detail, single point planning for principal movements out of DAL, ADS and DFW.
Access armored sedans, B6/B7 SUVs and discreet executive fleets from partner providers, dispatched to align with your protection schedule.
Aviation and ground services are provided by independent, separately licensed operators. Sentinel does not own aircraft or vehicles.
Verified by referral or counsel.
Matched to threat profile, geography and lifestyle.
Sentinel never holds your data or contracts.
We review insurance, registrations and references.
Background, operational and reputational review.
Visible only to credentialed principals on the platform.
Before a principal ever speaks to a firm, every request is handled under a binding NDA. Your identity, itinerary, household details, and risk profile remain encrypted and compartmentalised inside Sentinel. Firms see only what is strictly necessary to confirm fit, and only after they have signed our standard confidentiality undertaking. We do not sell data, share case histories, or market to the principals who trust us.
Each firm is presented as a complete dossier: license verifications, operational footprint, principal grade specialisations and discreet references. No marketing copy. No vanity metrics.
Names withheld at the request of the people quoted. References available to credentialed counterparties under NDA.
Sentinel cut a week of vendor calls down to two introductions. Both firms were already credentialed to the standard we required.
We've worked with most of the firms in this market. Sentinel is the only channel where the vetting matches what we actually look for in a partner.
For a sensitive movement on 72 hours' notice, the curated shortlist was the difference between an organised detail and improvisation.
Fewer than 1 in 9 firms that apply are admitted. Vetting is conducted by former counter intelligence and risk underwriting professionals, and re run on a rolling basis after admission.
Texas DPS Private Security Bureau licenses verified and re checked annually.
FBI channel background checks on principals, directors and every armed operative.
Minimum $5M general liability and armed rider cover from A rated US underwriters.
ASIS PSC.1, ISO 18788 or equivalent; TCOLE / DPS Level II, IV credentials current.
Demonstrable reach, response capability and local relationships.
NDA posture, data handling, OPSEC track record on prior principals.
Transparent, flat rate listing tiers. No per lead surprises, no commission on your contracts. One closed engagement typically covers a full year on the platform.
Sentinel does not take commission on your contracts. Booking, contracting and payment stay between you and the principal. Pricing may evolve as we add booking & escrow.
Sentinel opens to a small cohort each quarter. Tell us who you are, we'll reply from a private address within 48 hours.
Submissions are encrypted in transit and stored on a need to know basis.
No. Sentinel is a private marketplace. We do not employ operatives or deliver protection services ourselves, we connect principals with vetted firms who do.
Principal accounts are pseudonymised by default. Firms see only the information you choose to share, and only once you initiate contact.
Sentinel charges firms a fixed annual listing fee. Principals pay nothing. We never take a commission on engagements, your contracts are entirely between you and the firm.
Discretion compounds. A closed network of credentialed principals and rigorously vetted firms produces better matches and fewer leaks than an open directory ever could.
A standing committee of former counter intelligence officers, insurance underwriters and senior corporate security directors. Vetting is re run on a rolling basis.
We are admitting the first cohort of principals and firms this quarter. Waitlist applications are reviewed in the order they arrive.
