I’m Paul O’Brien, Corporate Resilience Manager and technical infrastructure analyst.
This site explores Operational Resilience at every layer—from organizational strategy to the protocols that keep digital systems running:
- Business Continuity & Crisis Management: Notes on the BCI Good Practice Guidelines (GPG 7.0), CBCI exam preparation, BIA methodologies, and ISO 22301.
- Core Internet Infrastructure: Independent analysis of email authentication (SPF/DKIM/DMARC), zero-access encryption, privacy-first tools, and deliverability.
I test tools independently to make complex digital dependencies legible before an outage forces the issue.
