Mimecast Expands APAC Investment to Accelerate Human Risk Management Growth

New Singapore leader, Regional HQ, and data center will strengthen operations and tackle emerging AI-driven risks for businesses 

APAC, December 16, 2025 — Leading cybersecurity business Mimecast today announced large new investments in Singapore to increase the company’s footprint in the Asia-Pacific (APAC) area. In order to provide organisations throughout the area with superior threat protection, data sovereignty, and AI innovation, a new ASEAN regional headquarters and an incoming data centre are part of this. Nicky Choo has been named Vice President and General Manager as part of this growth, overseeing Mimecast’s APAC operations, client success, and go-to-market strategy.

The Asia-Pacific region accounts for 25% of the global cybersecurity market, according to the Cyber Security Market Outlook. As the fastest-growing market worldwide, AI is seeing unprecedented demand fueled by rapid digital transformation, the rise of cloud-based services, and increasingly advanced cyber threats.

Marc van Zadelhoff, CEO, Mimecast, said, “Opening our regional HQ and forthcoming data center in Singapore, plus welcoming Nicky to lead APAC, are pivotal steps in our global growth strategy. APAC organizations are operating at the forefront of AI adoption and digital transformation – and face an equally rapid evolution in data loss and cybersecurity threats. Strengthening our local presence enables us to build region-specific innovations and deliver a world-class platform for reducing human risk.”

Nicky Choo Takes the Helm at Mimecast APAC

Nicky Choo has been named APAC’s general manager and vice president by Mimecast. Choo will oversee regional strategy, operations, and expansion in this crucial position, which will be based in Singapore. Mimecast has a solid regional base thanks to its Melbourne headquarters for Australia and New Zealand and its growing ASEAN workforce. Building on this momentum, Choo will lead Mimecast’s continued geographic expansion. Choo is in a good position to further Mimecast’s goal in the area because of its track record of assisting in the protection of some of the top brands in the world from cyberattacks. He has extensive experience in corporate technology and cybersecurity, having previously held top positions at Pegasystems and IBM and headed APAC operations at Devo.

“I’m incredibly excited to join Mimecast at this pivotal time for the cybersecurity industry,” said Choo. “Organisations across APAC are facing relentless, novel AI-driven attacks. The stakes have never been higher, and only the right security infrastructure can truly keep businesses safe. Mimecast’s platform is strongly positioned to leverage AI against these threats. Together, with our distribution partners, we’re ready to set a new standard for trust and security in the region.”  

Protection From, For and By AI

Mimecast’s 2025 Global Threat Intelligence Report highlights a dramatic shift in the cyber threat landscape. In particular, Shadow AI is emerging as a significant risk, with 86% of security leaders concerned about sensitive data leaking through generative AI tools.

To counter these evolving threats, Mimecast has developed advanced AI-powered solutions that help organisations minimize human risk and enhance threat detection. This includes Mimecast Insider Risk Management, which is designed to safeguard organisations from Shadow AI by protecting critical data from exposure, loss, leak and theft. The solution leverages advanced detection methods to rapidly spot potential data leaks and provide real-time alerts.   

Additionally, Mimecast intends to open a fully managed data centre in Singapore. The new data centre, which is built on top of AWS’s secure cloud architecture, will take advantage of AWS’s scalability and reliability while guaranteeing that local clients can satisfy stringent local data residency regulations, such as Singapore’s Personal Data Protection Act. Data sovereignty is more than just a legal need in the modern world; it is essential to security and trust. Mimecast’s new data centre will give businesses the assurance that their data infrastructure is secure and compliant by guaranteeing that sensitive data stays within national borders and is under local control.

Mimecast’s growth in the APAC region is anchored by its AI Lab in India, where a team of 150 engineers is dedicated to building an innovative, AI-driven platform that protects customers worldwide from advanced AI-enabled attacks. This expanding team not only strengthens Mimecast’s technical foundation but also sets the stage for continued regional growth and innovation.
