Prior to founding Boom, Peter founded and led Multiven, a pioneering pre-emptive cyber-defence software company that became a global leader in protecting critical Internet infrastructure. Long before the cybersecurity industry widely adopted "assume breach" and zero-trust principles, Multiven's operating model was built on the premise that every critical network should be treated as already compromised. Rather than relying solely on perimeter security, the company continuously identified, isolated and eliminated malicious actors while delivering trusted software integrity maintenance and security updates to continuously reduce attack surfaces, eliminate exploitable vulnerabilities, and restore the integrity of mission-critical systems.

Multiven's clients included critical government institutions such as the United States Department of Defense, the White House, and European law enforcement agencies, alongside telecommunications operators including AT&T, Orange, Telefónica, leading financial institutions such as Barclays Bank, and Fortune 500 and global enterprises including IKEA, AB InBev, Thales, Capgemini, Dassault Systèmes, Alcatel-Lucent, Nokia and among numerous other organisations responsible for operating critical infrastructure worldwide.

In 2008, seeking to strengthen the resilience of Internet infrastructure against cyberattacks, Multiven initiated the federal antitrust action Multiven, Inc. v. Cisco Systems, Inc. (Case No. 5:08-cv-05391, United States District Court for the Northern District of California), seeking to ensure that software and security updates were made available to customers using independent maintenance providers. Following Cisco's unsuccessful attempts to dismiss the case, the matter was resolved through a settlement under which Cisco agreed to provide software and security updates to Multiven and its clients, with the commercial terms of the ongoing relationship placed under seal at Cisco's request. The proceedings have been fully concluded, with no outstanding claims, liabilities or obligations remaining. Cisco and other original equipment manufacturers have since continued to provide software and security updates to Multiven in accordance with the settlement.

The outcome of the case is regarded as having helped promote competition in the enterprise software maintenance market and broaden access to critical security updates across the industry. The Multiven–Cisco settlement is a defining milestone that helped shape a more open and resilient Internet and laid the foundation for today's applications, including blockchain, digital assets and artificial intelligence.

Multiven was subsequently acquired by PhotonAI in 2025, as part of its strategy to build Archangel, an autonomous frontier AI cyber-defence system designed to detect, contain and accelerate remediation of emerging vulnerabilities across software-driven infrastructure. Archangel is being developed on the basis of Multiven’s multi-decade, multi-vendor security intelligence and operational experience, enabling PhotonAI to extend its pre-emptive cyber-defence model into next-generation autonomous systems for protecting critical infrastructure.
