Paul O'Brien - Insights

About Paul O'Brien, CBCI

Paul O'Brien is a Corporate Resilience Manager with over 25 years of technical experience spanning email architectures, DNS, and cloud infrastructure. He holds the CBCI credential (Certificate of the Business Continuity Institute), grounding his strategic insights in globally recognized standards (BCI GPG 7.0).

Underneath the risk matrices and continuity frameworks, Paul's technical roots run deep. He has spent two decades building, engineering, and dissecting core digital infrastructure—from untangling complex domain authentication protocols (SPF, DKIM, DMARC) and deliverability to auditing provider security and zero-knowledge privacy tools.

The Intersection of Security, Infrastructure & Resilience

Corporate resilience and core internet protocols are two sides of the same coin: Operational Risk.

  • The Strategic Lens: Business continuity keeps operations moving when disruption strikes—identifying single points of failure, mapping dependencies, and eliminating vendor lock-in.
  • The Technical Reality: Email systems, DNS, and privacy software are the quiet digital foundations of modern work. When your domain authentication breaks, your email provider experiences an unannounced outage, or a privacy vendor misleads its users, your operations and data are compromised in real time.

Email and digital privacy tools are rarely treated with urgency—until they fail. On Insights, Paul brings a risk-focused lens to software teardowns and infrastructure analysis so you understand how these tools really work before an outage or breach forces the issue.
