About Manish

Having been in cybersecurity for more than a decade as a leader in this space, I have had the benefit of exposure to both the industry and consulting sides of the industry. I began my journey as a penetration tester and in web application security, and later moved on to a leadership role where the emphasis was on constructing security that actually works for the organisation.

Experience in the consulting world, including at Deloitte, has given me the skills to quickly relate to diverse companies, sectors, and risk profiles—and to achieve security outcomes in a complex, dynamic setting. The industry experience that followed has given me the chance to leverage these learnings to build security into the long game, at scale. What I think is the right balance between leaning into the business to understand true priorities and constraints, and leaning out to develop a security strategy that is pragmatic, executable, and risk-informed.

I’ve collaborated with the engineering and product groups to enhance security on various platforms. I’ve kept business in mind in all these endeavours, aiming to enable the business unit rather than hinder it. It has been important for me to build strong relationships and communicate effectively.

As I have gained experience conducting assessments for private and public sector entities to help them address threats, certifications such as Lead Auditor 27001 and Cyber Threat Intelligence from GIAC demonstrate my keenness to learn and stay up to date in a domain that is constantly evolving.

    Head of Attack surface Management
    RETAIL (LARGE RETAILERS)
    September 2025 - Today (9 months)
    Delft, Netherlands
    As a cybersecurity leader at IKEA, I drive the strategy and execution of global security posture management to safeguard IKEA’s digital ecosystem across diverse markets and platforms. My focus is on building resilient defenses that align with IKEA’s values of simplicity, togetherness, and responsibility—ensuring security enables innovation, customer trust, and sustainable growth.

    Key areas of impact:

    Global Attack Surface Management – Proactively discovering, monitoring, and reducing exposures across the enterprise.

    Application & Cloud Security Posture – Embedding secure-by-design practices and scaling maturity across development and operations.

    Federated Governance – Establishing collaborative models that empower platform teams while ensuring global consistency and oversight.

    Security Enablement – Partnering with business and technology stakeholders to integrate security into digital transformation and retail innovation.

    Strategic Leadership – Building scalable global security programs that deliver measurable risk reduction and stakeholder trust.

    IKEA’s vision is “to create a better everyday life for the many people”—and in my role, I bring the same vision to cybersecurity: enabling safe, secure, and trusted digital experiences for colleagues, partners, and customers worldwide.
