Case Logs

A mid-market healthcare SaaS company faced elevated exposure from a widely exploited browser engine zero-day, amplified by inconsistent patch adoption across a macOS-heavy workforce. Leadership needed a response that reduced credential-theft and data-exposure risk without slowing product delivery, PLG growth motions, or day-to-day operations.

Established an emergency patch governance playbook that defined severity thresholds, decision rights, and time-bound SLAs for browser and endpoint updates, with clear escalation paths to executive stakeholders. Implemented lightweight reporting and enforcement coordination across IT and Security to confirm patch coverage, handle exceptions, and verify that compensating controls were in place for teams unable to update immediately.

Improved organizational readiness to respond to endpoint and browser zero-days with repeatable, auditable decision-making rather than ad hoc outreach. Reduced the likelihood of workstation-led credential compromise and downstream access to regulated customer environments, while preserving engineering focus by standardizing communications, timelines, and exception handling.

A mid-market healthcare SaaS provider offering embedded card payments discovered its annual PCI attestation and supporting artifacts were at risk of expiring, creating a pathway to payment processor escalations and potential processing restrictions. Ownership and scope for the cardholder environment were unclear across product, engineering, and operations, increasing the likelihood of missed renewal deadlines.

As fractional CISO, I re-established PCI scope boundaries, clarified control ownership via a lightweight RACI, and built an evidence map that tied required artifacts to specific systems and teams. I led the completion of the payment provider's PCI questionnaire, implemented an auditable renewal cadence with checkpoints, and created a repeatable artifact collection workflow to reduce last-minute compliance churn.

The organization restored on-time PCI attestation posture and reduced the risk of payment processing disruption tied to documentation lapses. Executive stakeholders gained a predictable compliance operating rhythm that minimized engineering interruptions while supporting revenue growth from the payments product. The program also improved readiness for customer security reviews by centralizing evidence and clarifying the cardholder data environment boundaries.

A mid-market SaaS platform supported regulated customers where authentication enforcement was inconsistent and email-based MFA and recovery increased account takeover risk. Leadership faced heightened exposure to sensitive-data allegations, customer disruption, and regulatory or contractual consequences if a compromised mailbox led to unauthorized access.

Led a platform-wide high-assurance MFA program using phishing-resistant or app-based factors, while deprecating email-based MFA and tightening recovery workflows. Centralized policy enforcement, defined rollout milestones and ownership, and aligned the change to the highest-risk customer segments first to reduce exposure quickly.

Reduced likelihood of account takeover in the highest-risk customer population and improved defensibility for audits and customer security reviews. Standardized authentication controls across the platform, lowering operational risk from fragmented enforcement and enabling clearer executive reporting on access-control posture.
