The new entity will offer managed security services, consulting, education, and leading-edge technologies to combat internal and external threats, Singtel said in a statement.

With this integration, Trustwave's global business has about 2000 security employees and a global network of 10 connected advanced security operations centres supported by the Trustwave SpiderLabs security team.

It also has millions of businesses enrolled in its cloud-based security platform, more than 10,000 managed security services customers, and nearly 1000 channel partners and numerous technology partners worldwide.

“Uniting the security assets and deep expertise of Singtel, Optus, Trustwave and NCS under one brand and single vision – what we call the new Trustwave - is a pivotal milestone for our customers, partners, employees and company,” said Arthur Wong, chief executive at Trustwave.

“Trustwave is well-positioned to further its role as a recognised leader in cyber security and managed security services, areas vital for effective security programs as enterprises accelerate their digital transformation.

"Customers benefit by having a trusted security partner with true global reach and intelligence, offering around-the-clock monitoring, detection and eradication of threats in addition to deep regional security expertise necessary for successfully addressing global threats and localised attack campaigns.”
