Mark Arena Learned to Read the Room. Then He Bought the Team.

Mark Arena remembers the Wildcats turning up at school. He remembers Christmas holidays in Busselton, too, and basketball camps run by Ricky Grace. These were encounters with a local team that stayed with him long enough to become part of his explanation for buying it. A player visits a classroom; years later, one of the children buys the club. Community engagement occasionally takes an unreasonably long time to reveal its commercial potential.

Between those two events, Arena acquired a rather different professional education. He wrote software, worked on technical investigations for the Australian Federal Police and helped organisations understand cybercriminals. Then he co-founded Intel 471, a company built around finding out what those criminals were doing before their plans became somebody else’s expensive problem.

In February 2023, he finished almost nine years as its chief executive. In August 2024, he became majority owner of the Perth Wildcats. By January 2026, the remaining shares had followed. The change brought a global cybersecurity entrepreneur into an unusually personal business: running the hometown basketball team whose school visits he could still recall.

The people behind the keyboard

Arena grew up in Greenwood, in Perth’s northern suburbs, attended Sacred Heart College and studied software engineering at Edith Cowan University. The technical work came first. Before his federal police years, he worked on embedded software for public transportation systems. His early career involved making things work inside the machinery of everyday life.

At the Australian Federal Police in Canberra, his job was technical specialist within High Tech Crime Operations. He has been precise about the distinction: he was a civilian specialist rather than a sworn officer. Investigations involving technical offenders needed capabilities that could not always be bought ready-made. Someone had to understand the problem and build a way through it.

He subsequently became chief researcher at iSIGHT Partners. The work widened to intelligence collection involving espionage, financially motivated cybercrime and hacktivism. Across these jobs, the object of attention was a person with intentions, connections and methods. A malicious file was evidence of an activity; understanding the people responsible required a wider view.

That view also shaped his writing. In a 2016 essay about observing adversaries, Arena advised organisations to start with their own attack surface and internal information. This was an intelligence vendor telling prospective buyers to pay attention to evidence they already possessed. The sales pitch left room for homework.

He also argued that useful intelligence depends on the organisation receiving it. Knowing about an impending attack only helps if somebody can decide what to do with that knowledge. For a customer, buying information leaves a second task unfinished: creating the capacity to respond. Arena’s point placed responsibility on both sides of the transaction, including the people paying the bill.

A business built before the funding

Arena and Jason Passwaters co-founded Intel 471 in 2014. Passwaters brought experience in the US Marines and FBI cybercrime work. Their backgrounds gave them a shared interest in the people and networks underpinning criminal activity, and in supplying intelligence that could help security teams act earlier.

The name arrived with less ceremony. Arena wanted intelligence in it. A number came to mind, the domain was available, and he proceeded. He later enjoyed the suggestion that a future venture might be called Intel 472, offering a very small numerical improvement. The naming committee, one suspects, would have struggled to justify an invoice.

The company grew without outside capital before its partnership with Thoma Bravo. Looking back in 2026, Passwaters described tight spending, reinvesting in the business and awkward early stretches when customer procurement cycles delayed the founders’ pay. Their efficiency came with an ordinary household consequence: explaining why the work had not yet produced a salary that month.

Thoma Bravo announced its strategic growth investment in September 2021, with both founders continuing to lead and retaining significant ownership. Its stated purpose included expanding the product range and the company’s route to customers. The deal was completed later that month. Arena had helped build something an investor could expand; the product still rested on knowledge accumulated by people doing the work.

The culture he wanted to leave behind

There was a management argument alongside the intelligence argument. Arena publicly emphasised humility, professional restraint, integrity and collaboration. He wanted employees to tackle problems directly and accept accountability. These were standards for how colleagues treated one another as much as for what they delivered to customers.

His departure message offered a compact version:

“Keep doing the right thing, even when it hurts.”

Mark Arena, February 2023

The timing matters. Intel 471 described 2022 as a record year when it announced the succession. Arena was leaving the executive role after strong results, with the other founder ready to take over. Passwaters became CEO on 1 March 2023; Arena transitioned to strategic advisor and retained his board seat. The company’s next phase would have continuity without requiring its founding CEO to keep the same job indefinitely.

Arena’s public writing also resisted the idea that a leader must wait for perfect knowledge. In 2017, amid debate about WannaCry, he defended analysts willing to make reasoned assessments from incomplete evidence. Uncertainty belonged inside the job. The obligation was to explain the judgement and its basis well enough for somebody else to use it.

A hometown attachment, paid in instalments

Arena had already returned to Australia in early 2022 after a decade in Europe. His own account places that move before the CEO handover. Coming home and leaving an executive position were separate decisions, rather than a single tidy exit scene.

The Wildcats purchase unfolded in stages. On 14 August 2024, Arena acquired an initial 52.5% for approximately A$21 million through MT Arena Capital Investment. A further 16.9% followed in November 2025 for A$6.5 million. In January 2026, Sports Entertainment Group announced completion of the final 30.6% for A$12 million. Total proceeds to the seller were A$39.5 million.

At the outset, Arena promised an emphasis on Western Australia. He acknowledged Jack Bendat’s legacy and the media reach brought by the previous owner, while proposing to add his own technology and business experience. The aim was stronger engagement among members, sponsors, the city and the wider basketball community. He was acquiring an organisation with relationships already in place, and people already attached to them.

The Red Army has opinions

Supporters soon had a formal invitation to contribute. Arena sought feedback about the club’s identity, including its logo, colours and mascot. He also raised the delicate matter of game-night music. A song that feels essential to one generation can sound like inherited furniture to another. Asking the question was easy enough; taking everyone’s attachment seriously was the more demanding part.

The ensuing rebrand involved agency Hum working with leadership and consulting fans before developing the visual identity. Its work connected the club’s presentation to its internal direction and place in Western Australia. A logo had to appear on a jersey, but it also had to belong to people who had worn the old one for years.

Basketball supplied less manageable changes. Arena’s first season ended with a one-point loss to Melbourne United that left Perth short of the championship series. In his letter to supporters afterwards, he called that opening season a learning experience and welcomed the prospect of a full offseason to plan. The owner had arrived shortly before the campaign; the competition supplied no introductory grace period.

Then came Bryce Cotton’s departure and eventual move to Adelaide in 2025. Arena defended the decision to move forward with building the rest of the roster after giving the player time to decide. By December, he was still explaining it publicly. A plan for an entire team had collided with supporters’ attachment to a defining player. Ownership gave him responsibility for the decision and an audience for the consequences.

He has also found room for mischief. On X in February 2026, Arena defended his freedom to tease fellow owners, naming Romie Chaudhari and Andrew Bogut. Professional restraint evidently allows the occasional basketball argument. A business that sells an evening’s entertainment can accommodate some in the owners’ conversation, too.

A longer game in Western Australia

Local ownership has a practical sporting dimension. Arena has advocated stronger ties with NBL1 West clubs and a preference for Wildcats players to spend their offseasons in Perth. Staying would allow them to keep working with coaches while contributing to the competition around them. The proposal links the professional team’s development to the basketball infrastructure beneath it.

His wider interests have continued alongside the club. Arena chairs DroneSec, and his 2023 submission to Australia’s cybersecurity strategy consultation urged clearer accountability and support for Australian cybersecurity talent. He argued that Australian capability could grow through companies incorporated overseas. Having established Intel 471 in Delaware while living in Europe, he had a concrete example behind the position.

More recently, the Wildcats’ 2026 Pirate Life partnership added a game-day meeting place and plans for a returning marching band. A September extension with Rio Tinto continued regional basketball activity, including clinics in the Pilbara. These are different ways of giving people an encounter with the club beyond the final score.

Arena now speaks about keeping the Wildcats in contention across seasons. His remembered childhood offers a useful measure for the other part of that ambition. Some of the club’s work will be judged on the night, in full view of the crowd. A school visit may take decades to deliver its verdict.
