Top 75 accounting firm Sensiba has acquired AssuranceLab Pty. Ltd., a cybersecurity audit and risk assurance firm headquartered in Sydney, Australia, with additional offices in Austin, TX, and Dublin, Ireland.
Financial terms of the deal weren’t disclosed. Clients will continue working with their existing teams—there will be no reintroductions or disruption to service, the firms said in an April 30 media release.
Sensiba said the deal expands its international reach and deepens its capabilities in security, privacy, and compliance frameworks. Together, the combined firm now supports more than 2,300 startup and technology-driven enterprise clients worldwide—providing streamlined audits across more than 15 compliance standards, including SOC 2, ISO/IEC 27001, HIPAA, CSA STAR, and HITRUST.
“We’re honored to welcome AssuranceLab to Sensiba. Their reputation in the market is well-earned, driven by innovation, credibility, and a commitment to raising the bar for cybersecurity audits. What makes this such a strong fit is the alignment across our values and client service philosophies—and our vision for the future,” John Sensiba, managing partner at the San Ramon, CA-based accounting firm, said in a statement. “Both of our firms have built deep relationships with startups and technology companies—businesses that increasingly recognize how cyber threats, ESG risk, and privacy concerns impact investor confidence, market relevance, and talent retention in a global landscape. AssuranceLab’s technology-forward approach and entrepreneurial spirit will be central to how we continue supporting clients with the insight, scale, and expertise they need for rapid growth.”
Both firms are Certified B Corporations, a designation from global nonprofit B Lab that certifies a business is meeting high standards of verified performance, accountability, and transparency on factors from employee benefits and charitable giving to supply chain practices and input materials.
Sensiba said the acquisition brings a broader range of services, including cybersecurity consulting and penetration testing while “maintaining a client-centric, tech-enabled audit experience that both teams are known for.”
“We’re excited to take this next step in AssuranceLab’s journey,” said Paul Wenham, co-founder and co-CEO of AssuranceLab and now a Sensiba partner. “Sensiba shares our client-first and technology-led approach to client service, and their people radiate the kind of values we deeply respect. Joining Sensiba gives us a platform to bring our innovative programs, audit models, and tech to a broader audience, and to have more impact as our clients navigate increasingly complex assurance and compliance challenges.”
“What excites us most about coming together with Sensiba is the opportunity to build on our tech-forward foundation while tapping into new expertise, geographies, and ideas,” added Nicholas Lew Ton, co-founder and co-CEO of AssuranceLab and now a Sensiba partner. “The compliance and risk landscape is changing rapidly, and clients value innovation as we lead the next wave of modern, meaningful audits.”
