Cybersecurity for Family Offices

Family offices manage what matters most—generational wealth, family legacies, and private information about what is most personal: your assets and loved ones. Yet many remain defenseless while facing threats designed for Fortune 500 targets.

The problem is pervasive: 57% of family offices in North America  have experienced a cyberattack in the past two years, with half suffering three or more attacks. 

When hackers succeed, the damage goes far beyond financial loss: total compromise of private family communications and financial records. Ransomware holding your entire digital infrastructure hostage. Breaches exposing your broader network—advisors, business partners, family connections—undermining the trust and standing you've built in your community.

The good news? With strategic guidance and smart investments in the right defenses, family offices can significantly reduce these risks without adding operational complexity.

Enterprise Grade

We draw from proven expertise across the intelligence community, big tech innovation, and financial services—the same caliber of security that manages billions in daily trading. Deep knowledge of the cybersecurity ecosystem means you get only the most effective partners and solutions, not whatever a vendor is pushing.

Custom

Based on deep security expertise and an understanding of the latest threats, we build bespoke defenses for the challenges your family actually faces—whether that's executive impersonation, infrastructure vulnerabilities, or regulatory compliance. We distill our ecosystem perspective into what you need to know.

We take down malicious infrastructure, restore your defenses, and communicate clearly with those impacted—getting you back on solid ground quickly with actionable recommendations to prevent future incidents.

Microsoft 360 & Google Workplace Security
