Managed Cybersecurity · GRC Consulting

Your IT team wasn't hired to be a security team.

We handle your cybersecurity. You run your business.

Managed cybersecurity services for companies between 50 and 500 employees.
Large companies pay millions for cybersecurity. We deliver it for a fraction of that and run it for you.

Who We Serve

Built for organizations with real exposure and limited resources.

Fideseo® is a management consulting and cybersecurity firm built for organizations that have real exposure but not the resources to address it fully.

  • Companies between 50 and 500 employees without a dedicated security team
  • Organizations with one IT generalist, or an IT person with a cyber background, who needs real backup
  • Regulated businesses and non-profits managing compliance obligations they can't meet on their own
60%+ of breaches originate with vendors

How It's Different

Not a cybersecurity tool. A managed security services team.

Most cybersecurity platforms assume you have someone to run them. You don't, and you shouldn't need to.

GRCDefense® is built to be operated by us, not by you. Our CISO-led team actively monitors your environment, translates every finding into plain English, and executes the remediation. You review the briefing. We handle the rest.

CISO-Led Execution

Our team handles the work. You're not left with findings and no path forward.

Talk to our team

A GRC consulting firm helps organizations manage governance, risk, and compliance. That means building security programs, preparing for audits, managing vendor risk, and ensuring your operations meet regulatory requirements. Fideseo® combines GRC consulting with GRCDefense®, a managed security platform that handles the ongoing operational work for companies between 50 and 500 employees.

GRCDefense® is a managed security platform that delivers six cybersecurity capabilities: vulnerability management, penetration testing, compliance, threat hunting, code security, and phishing simulation, run by our team on behalf of clients who don't have dedicated security staff.

A consultant delivers a project and leaves. GRCDefense® is an ongoing managed program, with a proprietary platform, where your environment is actively monitored, findings are delivered monthly in plain English, and our team handles execution. You get the results of a security team without the cost of building one.

A cybersecurity consultant delivers a project, a report, or a recommendation, then leaves. Managed cybersecurity services mean an ongoing team operates your security program month after month. GRCDefense® is a managed security services program: our team actively monitors your environment, delivers monthly findings, and handles the work.

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