Cybersecurity Advisory

Strategy and program build, fractional/interim CISO, implementation and technical guidance, OT/critical-infrastructure security, operations, compliance and assurance

Who this serves: enterprises, data center and critical infrastructure operators, private equity portfolio companies, and growth-stage technology firms. Vendor-neutral by design: RSF resells nothing and takes no platform commissions — the advice is the product. Credentials: former FBI senior executive (cyber and critical infrastructure), former North America security practice partner at PwC, former global CISO of Digital Realty (NYSE-listed data center REIT).

Strategy & Program Build

•    Enterprise security strategy aligned to business model, revenue protection, and risk appetite — not framework theater

•    Program stand-up from zero: governance, policy architecture, organizational design, budget construction, multi-year roadmaps

•    Board and audit committee reporting: metrics, risk quantification, and narratives that earn budget and trust

•    Security operating model design: build/buy/partner decisions, MSSP selection and oversight

Fractional & Interim Executive Leadership

•    Fractional CISO for organizations not ready for a full-time executive; interim CISO coverage during transitions

•    First-CISO stand-up for companies crossing the maturity threshold; hiring, onboarding, and mentoring the permanent successor

•    Executive advisor to sitting CISOs: board preparation, crisis counsel, career-grade decisions

Implementation & Technical Guidance

•    Control architecture guidance: identity and access, network segmentation, monitoring, detection and response stack design

•    Vendor and tool selection with genuine neutrality — requirements definition, evaluation, negotiation support

•    OT / ICS / building-systems security for mission-critical facilities: BMS, EPMS, DCIM environments; IT/OT convergence

•    De-risking OT security platform deployments in live, uptime-sensitive environments — the gap between buying the tool and it working

•    Data center and critical infrastructure security: design-stage security for new builds, physical-cyber convergence, tenant/provider responsibility models

Board & Audit Committee Advisory

•    Board preparation strategy: readying management teams and materials for board-level cyber discussions that go well

•    Audit committee briefings on cybersecurity and related risk matters — delivered as a stand-in for the CISO, alongside the CISO, or in support of independent auditors

•    Independent third-party briefings when the committee needs a voice with no stake in the budget being defended

•    Translation of technical security posture into fiduciary and disclosure language directors can act on

•    Pre-audit and pre-earnings cyber readiness reviews; oversight documentation that stands up later

Operations & Resilience

•    Incident response planning, playbooks, and executive tabletop exercises; ransomware readiness and recovery governance

•    SOC and detection maturity assessment; threat intelligence program design; insider risk programs

•    Crisis leadership: on-call senior counsel to executives during live incidents

Compliance & Assurance

•    SOC 2, ISO 27001, and NIST CSF readiness; audit preparation; independent-attestation strategy

•    Federal-adjacent orientation: CMMC, DFARS, CUI handling — segment selection and certification sequencing

•    Third-party and supply chain risk programs; M&A security due diligence (buy-side and sell-side)

•    AI-era security: securing AI infrastructure and workloads, AI governance frameworks, security implications of AI adoption
