Artificial intelligence is changing not only how organisations defend themselves, but also what they need to protect. As AI becomes embedded in collaboration platforms, business applications and operational workflows, it is increasingly influencing – and in some cases making – decisions that were once left to people.

That changes the cybersecurity challenge fundamentally.

Rather than simply protecting infrastructure or data, organisations are beginning to face a new priority: protecting the integrity of decisions.

The implications stretch well beyond traditional IT departments. Corporate communications, unified communications, meeting platforms and collaboration technologies are increasingly connected to AI-powered assistants, automated workflows and intelligent business systems. As these technologies become more capable, the quality and trustworthiness of the information they consume becomes just as important as the security of the networks they run on.

These themes were explored in the session The Invisible Shield: Securing Corporate Communications at the ISE 2026 CyberSecurity Summit, which examined how AI is reshaping both the threat landscape and the way organisations need to think about trust, communications and decision-making.

The threat landscape is evolving just as quickly.

Cybercriminals are already using AI to generate highly convincing phishing campaigns, clone voices, create realistic deepfake videos and automate social engineering attacks at a scale that would have been unimaginable only a few years ago. The cost of producing convincing fake content has fallen dramatically, making sophisticated attacks accessible to far more threat actors than ever before.

The objective is often no longer to break into a system. Instead, it is to persuade a legitimate user to make the wrong decision.

That distinction matters.

An employee who voluntarily authorises a fraudulent payment, shares confidential information during what appears to be a legitimate video call, or follows instructions from an AI-generated impersonation of a senior executive may bypass every traditional security control. The infrastructure remains secure. The human decision does not.

As organisations increasingly deploy AI agents to analyse information, recommend actions and automate routine processes, another challenge emerges. How do you know the AI itself is making trustworthy decisions?

The quality of an AI system depends on the data it receives and the models that interpret it. Manipulated training data, poisoned information sources or compromised inputs can influence recommendations long before anyone notices something is wrong. Protecting AI therefore means protecting the trustworthiness of the entire decision-making chain.

For technology leaders, this requires a broader view of cybersecurity. Strong authentication, encryption and endpoint protection remain critical, but they must be complemented by governance of AI models, validation of data sources, continuous monitoring of automated systems and ongoing investment in user awareness.

In other words, cybersecurity is becoming as much about confidence as control.

This convergence of AI, enterprise communications, AV and cybersecurity is creating entirely new conversations across the technology industry. As intelligent collaboration tools become central to how organisations operate, security can no longer be considered a specialist discipline sitting alongside communications technology. It is becoming an integral part of the user experience itself.

These are exactly the kinds of cross-disciplinary challenges being explored at ISE, where cybersecurity, AI, networking, enterprise communications and professional AV are increasingly viewed as interconnected parts of the same technology ecosystem rather than separate disciplines.

The organisations that adapt fastest will not simply build stronger digital defences. They will build systems that people – and increasingly AI – can trust to make the right decisions.
