About Stephen Webster

I serve as an Interim and Fractional CIO/CISO for private and private‑equity–backed energy and infrastructure companies, stepping into complex environments where digital resilience, operational continuity, and investor confidence are on the line. My work centers on stabilizing technology, reducing risk, and accelerating value creation across the portfolio.I solve the problems that surface in the hardest moments of the deal cycle — M&A diligence, carve‑outs, TSA exits, cyber uplift, IT rebuilds, and post‑transaction integration. Whether the mandate is to stand up a new IT function, unwind legacy technical debt, or restore trust after a cyber event, I bring the structure and speed PE sponsors and Executive Management Teams expect.My approach is built on repeatable, battle‑tested frameworks: a 90‑day CIO playbook for rapid stabilization, a cyber uplift model aligned to investor risk thresholds, and an integration blueprint that compresses timelines while protecting business continuity. These tools allow me to enter quickly, diagnose accurately, and execute with discipline.I’ve delivered results across organizations including Crossbridge, Entara, LRE, Enchanted Rock, StratITsphere, and BG Group — leading transformations, rebuilding core systems, maturing cyber posture, and guiding leadership teams through high‑stakes operational and transactional change.I accept a limited number of concurrent engagements.
