Oscar Elleseff Consulting
Executive technology and security leadership for growing organizations — delivered without the overhead, or the cost, of a full-time hire.
Start a ConversationWhat Sets This Apart
The ability to walk into an organization and rapidly diagnose what's actually wrong — on the technology side or the security side — and know exactly what needs to happen next.
The Practice
01
On-demand technology executive leadership — strategy, delivery, team-building, and governance for organizations that need CIO-level leadership without a full-time seat.
02
On-demand security and risk executive leadership — building and running security programs grounded in real operating experience, not theoretical frameworks.
03
Emerging leadership for organizations that need AI governance and strategy without a full-time hire — separating genuine value from technology for its own sake.
How Engagements Begin
A focused capability or security assessment identifies what's actually wrong — then informs a clear roadmap or program before ongoing execution begins.
For organizations ready to move immediately. Work begins directly on current priorities, and an accurate picture of the organization builds through the work itself.

The Engagement Model
Engagements are billed hourly, typically around two days a week, flexing up to three when needed. Beyond three days a week is usually a sign an organization needs a full-time executive rather than a fractional one — worth knowing upfront.
