Penten, Amiosec Merge into $125M Cybersecurity Firm PentenAmio

Australian cybersecurity firm Penten and UK-based Amiosec have completed a merger to form PentenAmio, a new entity specializing in sovereign cybersecurity, electronic warfare, and secure mobile communications for government and military clients. With approximately 300 security-cleared professionals and operations in both Australia and the UK, PentenAmio is positioned as one of the largest teams globally dedicated to classified communications and AI-enabled cyber defense. The merged company will generate over $125 million in annual revenue, supporting continued investment in research, development, and global expansion. Leadership includes Penten and Amiosec founders Matthew Wilson and Adrian Cunningham as executive co-chairs, with Matt Thomas appointed CEO of UK operations and Sarah Bailey leading in Australia. PentenAmio's proprietary technologies are trusted by more than 20 national security and defense organizations across the UK, Australia, and Canada, and the company plans further expansion into NATO-aligned markets. No redundancies resulted from the merger, and the business remains privately held with support from Five V Capital as a minority shareholder.
