What Gdb Security does
GDB Security LLC is a privately held boutique cybersecurity advisory firm founded in 2024 by Gary Belvin and headquartered in Boston, Massachusetts. The firm delivers concierge cybersecurity services exclusively to family offices, addressing the gap between enterprise-grade threat exposure and the limited in-house defenses most high-net-worth families maintain. Its service portfolio comprises eight integrated advisory offerings: Risk Analysis, Threat Briefings, System Design & Hardening, Vendor Identification & Coaching, Digital Privacy & Reputation Management, Microsoft 365 and Google Workspace Security, Compliance Support, and Incident Response. The firm positions itself as a 'Security Quarterback' that coordinates bespoke, high-ROI defenses without the operational complexity of large-scale enterprise security programs.
The firm's primary technical differentiator is the founder's background rather than a proprietary software platform. Gary Belvin's career spans the NSA intelligence community, a fintech CISO role securing AI trading algorithms that handled over 10% of daily US equity trading, current AI security work at Databricks, and authorship of cryptographic innovations that power encryption inside WhatsApp, Signal, and iMessage (collectively securing approximately 3.6 billion daily active users). He also convened a coalition of 30 Fortune 100 CISOs that shaped Executive Order 13800 on America's cyber defenses. This concentration of credentials — intelligence community, fintech, AI security, applied cryptography — is the foundation of the firm's advisory IP.
GDB Security operates a pure professional services revenue model with quote-based engagements and annual billing cadence. Distribution is direct enterprise field sales: high-touch consultative outreach through a website 'Book a Consultation' CTA (powered by reclaim.ai), supplemented by an email newsletter, conference speaking at international business attorneys events, and referral-driven trust-building via legal and financial advisor networks. The firm is privately held by its founder with no disclosed institutional investment, no disclosed headcount beyond 1-10 employees, and no public revenue figures. Named credibility relationships include Smallstep, Tailscale, and Hutchings Barsamian Mandelcorn LLP.

Gdb Security competitors and assessment
Company assessmentDirect peers
- Foresite Cybersecurity: Foresite provides managed cybersecurity and compliance services to mid-market and high-growth organizations, including fractional CISO offerings. It overlaps with GDB's advisory-led model and competes for similar buyers seeking outsourced cybersecurity leadership without a full internal team.
- BlackCloak: BlackCloak provides concierge cybersecurity and digital executive protection services for high-net-worth individuals, executives, and family offices. It is the most directly comparable peer to GDB Security given its overlapping boutique positioning, similar buyer persona, and shared focus on personalized cybersecurity outside the enterprise MSSP mold.
- LMG Security: LMG Security is a boutique cybersecurity firm offering penetration testing, incident response, and vCISO services to small and mid-sized organizations. Its boutique, senior-practitioner delivery model and incident response practice are closely comparable to GDB's concierge advisory approach.
- Pivot Point Security: Pivot Point Security is a boutique cybersecurity advisory firm specializing in risk assessments, compliance, and vCISO services. It serves as a comparable boutique alternative to GDB, particularly for organizations seeking high-touch consulting rather than scaled managed services.
Emerging players
- Concentric AI: Concentric AI is a data security posture management vendor focused on autonomous discovery, classification, and risk remediation for sensitive data. While product-led rather than advisory-led, it competes for the same data security and privacy budget line items GDB addresses through consulting.
Broad incumbents
- Herjavec Group: Herjavec Group is a well-known cybersecurity services firm offering advisory, managed security, and incident response across enterprise and high-net-worth segments. It competes for the same trusted-advisor positioning and incident response engagements as GDB, with a much larger bench.
- Arctic Wolf: Arctic Wolf is a leading managed security services provider offering 24x7 SOC-as-a-service and concierge security operations. It competes for outsourced cybersecurity budgets and has been expanding into higher-touch advisory tiers relevant to mid-sized and high-net-worth buyers.
- Pinkerton: Pinkerton is a global corporate security and intelligence firm with longstanding practice serving wealthy families and family offices. Its protective services and investigations overlap with GDB's incident response and digital privacy mandates, although delivered through a much larger corporate security lens.
- eSentire: eSentire is an MDR-focused MSSP delivering managed detection and response with dedicated security analysts. It represents the scaled, technology-led alternative to boutique advisory models like GDB's for organizations seeking outsourced cyber operations.
- Kroll: Kroll is a global risk consulting firm with a dedicated cyber risk practice that serves high-net-worth clients, family offices, and corporate boards. While it is far larger and broader than GDB, its HNW cyber advisory work competes for the same buyer budget and uses a similar trusted-advisor posture.
