About Fideseo®

A management consulting and cybersecurity firm built around one conviction: mid-sized companies deserve the same quality of security program as large enterprises, delivered in a way they can actually afford and sustain.

The Company

Who we are.

Fideseo® is a management consulting and cybersecurity firm based in Ponte Vedra, Florida. We serve companies between 50 and 500 employees that have real security obligations but can't build or sustain a dedicated security team at enterprise cost.

Our primary offering, GRCDefense®, is a managed security platform that delivers six active cybersecurity capabilities operated by our team. We also provide fractional CISO services, vendor risk management through Vendor Fidelity®, GRC Advisory for compliance programs, and AI governance for organizations deploying AI tools.

Fideseo® is headquartered in Ponte Vedra, Florida. We work with clients nationally and outside the US.

Why Fideseo®?

The name comes from the Latin root fides, trust, reliability, good faith. It reflects the conviction that security and compliance work is fundamentally about building systems your clients, partners, and regulators can trust. The work only matters if it's real.

How We Work

What you should expect from us.

Honest Assessment

We tell clients what their actual security posture is, not what they want to hear. An honest gap assessment is more valuable than a comfortable one.

Plain English

Security findings delivered in language leadership understands. We translate technical risk into business terms, because decisions get made by people who aren't reading CVE reports.

Execution Accountability

We don't deliver reports and leave. Our team owns the work, the monitoring, the remediation, the compliance maintenance, month over month.
