About the role

We are looking for a Director‐level Field CISO to join our Security function and report directly to the Global Field CISO. Based in London with two days per week in the office, you will serve as the primary trusted security advisor across our most strategic accounts in EMEA, operating at the intersection of customer success, executive advisory, and industry thought leadership. This position involves advisory support rather than pre‐sales or support functions and requires a deep understanding of human risk and technology integration.

What You'll Do

• Act as trusted advisor to CISOs, CTOs, and board‐level stakeholders at top strategic accounts across EMEA, helping them build and mature their human risk management programmes.
• Guide customers through insider risk strategy, Incydr deployment, AI agent risk, and enterprise risk frameworks, translating Mimecast platform capabilities into measurable business outcomes.
• Support customers through audits, regulatory examinations, and compliance programmes across a fragmented regional landscape (PDPA, DIFC, POPIA, Saudi NCA, and more).
• Provide rapid response to security incidents affecting customers, regardless of direct product impact.
• Represent Mimecast at major EMEA security conferences (GISEC, GITEX, Black Hat MEA, sector‐specific FSI and government events) and advance the human risk narrative.
• Author whitepapers, research reports, and opinion pieces on human risk, insider threat, AI security, and the evolving threat landscape.
• Build and sustain a credible public profile across EMEA that extends the Global Field CISO's reach and reinforces Mimecast's position as the human risk authority in the region.
• Partner with sales on security‐sensitive enterprise deals, shortening sales cycles and lifting win rates through advisory credibility in regulated sectors.
• Support land‐and‐expand motions by deepening relationships within existing accounts and surfacing expansion opportunities.
• Log all advisory‐linked opportunities in CRM to build evidence of Field CISO ROI and demonstrate how security advisory translates to customer outcomes.
• Feed structured customer insights back to product and engineering to surface gaps in human risk capabilities and product features.
• Advocate for reductions in customer audit and compliance toil by pushing for product changes that simplify evidence collection.
• Contribute to the Mimecast CISO Customer Advisory Board (CAB) and regional CISO community events, building a customer community that values Mimecast as a long‐term security partner.

What You'll Bring

• Depth of experience in enterprise information security, with more than 10 years in a leadership role, including at least 3 years as a CISO, VP of Security, or equivalent within an enterprise. Operational experience is mandatory.
• Bachelor's degree in computer science, information technology, cybersecurity, or a related field (Master's preferred) or equivalent senior security leadership experience.
• Advanced certifications: CISSP, CRISC, CISM, GCEIT, or equivalent GIAC.
• Proven ability to engage and influence C‐suite and board audiences with credibility and humility.
• Prior exposure to multiple EMEA sub‐regions with genuine cross‐cultural fluency.
• Comfortable operating as a Director‐level individual contributor without day‐to‐day management oversight.
