Field CISO EMEA

About Mimecast

Mimecast is a global cybersecurity leader redefining how organisations secure human risk. Our AI‑powered, API‑enabled Human Risk Management platform is purpose‑built to protect organisations from the full spectrum of cyber threats – integrating cutting‑edge technology with human‑centric pathways to deliver visibility, strategic insight, and decisive action. More than 42,000 businesses worldwide trust Mimecast to keep ahead of an ever‑evolving threat landscape.

We are one of only three vendors globally to achieve Leader status in both the Gartner® Magic Quadrant™ for Email Security and DCGAS. Our platform spans email security, insider risk management (Incydr), human risk awareness and training (Mimecast Engage), and the Human Risk Command Center – a single pane of glass that scores, surfaces, and enables action on human risk across an entire organisation. Most recently, we expanded Incydr into runtime data security, providing unified visibility across both human and AI agent risk.

Across EMEA, Mimecast has established offices in Dubai, Johannesburg, Cape Town, Bengaluru, Melbourne, and Sydney. The Field CISO is based in London, travelling to these regions to strengthen local relationships. Through our Resilience Together corporate social responsibility programme, we also invest time, resources, and funds in underserved communities.

About the role

We are looking for a Director‑level Field CISO to join our Security function, reporting 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 – Europe, the Middle East, and Africa.

This is not a pre‑sales or support role. You will operate at the intersection of customer success, executive advisory, and industry thought leadership, extending the Global Field CISO’s strategy into a region too diverse and commercially significant to be served from a central function. You bring your own credibility, relationships, and point of view – and you use them to make customers genuinely more secure.

In practice, you help CISOs across EMEA navigate the human risk challenge: most breaches trace back to human behaviour – negligent, compromised, or malicious. You provide visibility across email, collaboration tools, endpoints, SaaS applications, and AI agents, translating Mimecast’s platform into measurable business outcomes.

What You’ll Do

• Act as a trusted advisor to CISOs, CTOs, and board‑level stakeholders at the company’s top strategic accounts.
• Guide customers through insider risk strategy, Incydr deployment, AI agent risk, and enterprise risk frameworks.
• Support customers through audits, regulatory examinations, and compliance programmes across the region (PDPA, DIFC, POPIA, Saudi NCA, and more).
• Be the first call when a customer has a security problem – run toward the problem, not away from it.
• Represent Mimecast at major EMEA security conferences – GISEC, GITEX, Black Hat MEA, and sector‑specific FSI and government events.
• 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, extending the Global Field CISO’s reach.
• Partner with sales on security‑sensitive enterprise deals – shortening sales cycles and lifting win rates, especially in regulated sectors.
• Support land‑and‑expand motions by deepening relationships within existing accounts and surfacing opportunities to expand Mimecast adoption.
• Log all advisory‑linked opportunities in CRM to build evidence for Field CISO ROI.
• Feed structured customer insights back to product and engineering.
• Advocate for reductions in audit and compliance toil by pushing for product changes that simplify evidencing conformance.
• Contribute to the Mimecast CISO Customer Advisory Board (CAB) and regional CISO community events.

What You’ll Bring

• 10+ years in enterprise information security, with at least 3 years as a CISO, VP of Security, or equivalent inside an enterprise. Lived operational experience is non‑negotiable.
• Bachelor’s degree in computer science, information technology, cybersecurity, or a related field (Master’s preferred) – or equivalent experience at senior security leadership level.
• Advanced certifications: CISSP, CRISC, CISM, GCEIT, or GIAC equivalent.
• 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 – highly self‑directed, no day‑to‑day management oversight.
