Estate & family office security

Security leadership for households and principals who require discretion, not disruption.

0300 Group extends its physical security methodology to private estates, family offices, and executives whose exposure is personal rather than corporate — the same rigor, applied quietly.

Service lines

Every engagement begins with a private conversation, not a proposal. No pricing is published — scope and fee are confirmed in writing after we understand your situation.

Estate
Estate Security Assessments
A property-level review of the residence and its perimeter — access points, key and credential management, staffing and post orders, and the household's emergency, evacuation, and continuity procedures.
Principal
Executive & Principal Threat Assessments
An evaluation of the risks specific to a principal rather than a property — travel exposure, public presence, and available personal information — resulting in a prioritized, practical briefing.
Protection
Executive Protection
Protective coverage for travel, appearances, and elevated-risk circumstances, built around preparation and readiness rather than visible presence for its own sake.
Licensed
Investigations
Licensed investigative support for household staff and vendor vetting, due diligence, and matters that require a discreet, professional inquiry.

Judgment developed where being wrong had consequences.

Trevon Sailor holds a California Private Investigator license and built his security practice at the intersection of law enforcement investigations and executive protection — work that required the same qualities a family office or private principal expects: discretion, sound judgment under uncertainty, and a habit of anticipating problems before they surface. That grounding, developed over years of protective and investigative work, now shapes how 0300 Group approaches estate and principal security: fewer assumptions, more verification, and a plan for what happens if something goes wrong.

"Our clients don't want to think about security. They want to trust that someone already has — quietly, and without being asked twice."
