Work with me · Fractional & interim technology leadership

# Fractional and interim CIO, CTO, and CISO.

When an organization needs senior technology leadership now — after a departure, in the middle of a turnaround, or before a hire it isn't ready to make — I step in as a fractional or interim CIO, CTO, or CISO. I take these engagements through [Fortium Partners](https://www.fortiumpartners.com/partners/brian-greenberg), where I'm a Senior Partner.

Engagement models

## Three ways to bring me in

### Fractional

A standing part-time seat at the leadership table: strategy, budget, vendor and risk decisions, and a steady hand on the technology team, for organizations that need executive judgment but not a full-time executive.

### Interim

A full-time, fixed-term executive while the permanent role is open or the organization is in transition. The goal is to stabilize, make the hard calls, and hand over a function that is in better shape than I found it.

### Advisory

A second opinion for a CEO or board on the technology decisions that are hard to undo: security, data, risk, and the systems the business quietly depends on. Advisory work runs through [General System Dynamics](https://gsysd.com), my own practice.

Where I help

## What an engagement usually covers

### IT strategy and operations

Enterprise systems, IT operations, software implementation, and process improvement.

### Cybersecurity and risk

Security programs built from nothing, SOC 2 compliance and governance, risk mitigation, and board-level cyber reporting.

### Resilience

Business continuity, disaster recovery, and data protection that has actually been tested.

### Cloud and architecture

Cloud architecture, data center strategy, and the product and platform decisions that follow from it.

### Turnaround and change

Digital transformation, stabilizing a team in its worst year, and organizational change grounded in systems thinking.

Questions

## Frequently asked

### What is a fractional CIO?

A fractional CIO is an experienced chief information officer who works part time for an organization, on an ongoing basis, instead of a full-time hire. The organization gets executive-level technology judgment for strategy, budget, security, and vendor decisions at the depth it actually needs.

### How is an interim CIO or CTO different?

An interim executive is full time for a fixed term, usually while a permanent leader is being recruited or during a turnaround, merger, or other transition. A fractional executive is part time and can stay for years.

### Do you also serve as a fractional or interim CISO?

Yes. I have led security programs as a CIO/CISO, I teach cybersecurity at DePaul University, and I write about security leadership for the Forbes Technology Council.

### How do I engage you?

Fractional and interim engagements are arranged through Fortium Partners; advisory work runs through General System Dynamics. Either way, use the [contact form](https://briangreenberg.net/contact/) or my [Fortium Partners profile](https://www.fortiumpartners.com/partners/brian-greenberg), and we'll start with a conversation about what the organization needs.

### Where are you based, and where do you work?

Chicago, Illinois, working with organizations anywhere in the world. Engagements can be remote, on site, or a mix.

## Need a technology leader now?

Tell me what's going on. The first conversation costs nothing and usually clarifies whether you need a fractional executive, an interim one, or neither.
