Five Global Cybersecurity Trends to Watch in 2025
Technological advancement has ushered in a new wave of innovation and efficiency—but it has also opened the door to vulnerabilities that cyber attackers are eager to exploit. With billions in damages and reputational costs at stake, businesses must evolve their security posture to match these emerging threats.
As cybersecurity continues to evolve in 2025, organizations around the world will have to rethink their approach to protecting their most critical assets and operations. Here are five cybersecurity trends to watch in 2025 and beyond.
1: Attacks on operational technology will increase
No longer content to target IT, cyber attackers are increasingly taking aim at critical operational technology (OT) systems. Prominent examples like the Colonial Pipeline [i] and MGM Grand [ii] attacks demonstrate the way that threat actors are now more focused on completely shutting down facility operations instead of just stealing information.
This shift shows how cybercriminals and state-sponsored groups are evolving their tactics to inflict a more direct, crippling impact on business operations globally. In 2025, protecting OT systems from these types of targeted, disruptive attacks will be a major cybersecurity challenge for industrial organizations.
2: Cybersecurity regulation will intensify
Globally, governments are recognizing the systemic risks posed by attacks and are taking a more active and collaborative role in driving cybersecurity best practices. This will significantly impact the way that organizations approach security. For instance, there are now regulations like the European Union’s NIS2 Directive [iii] that can hold executives personally liable if appropriate security measures are not implemented at their organizations. This will drive stronger collaboration among government and the C-suite, boards and cybersecurity leaders.
In the U.S., there are new SEC rules [iv] that require prompt reporting of cyberattacks to provide greater protection for investors. Meanwhile, Australia is set to implement stringent cyber regulations of its own through the Security of Critical Infrastructure (SOCI) Act [v] . Though SOCI was first enacted in 2018, the grace period for compliance ended in August 2024. This means that going forward, Australian organizations in critical infrastructure sectors will now be required to comply with this enforceable regulation or face potential fines.
Overall, organizations across the globe will have to closely monitor evolving government regulations and align their security strategies accordingly to avoid penalties and reputational damage in the coming year.
3: Asset visibility will improve
In 2025, a key cybersecurity challenge for organizations, particularly building operators, will be gaining full visibility into the myriad connected assets on their networks. Many building owners struggle to identify all the connected devices, from security cameras to HVAC systems to access control panels, which make up their OT infrastructure. Without a clear understanding of their complete asset inventory, organizations are unable to effectively defend against threats. Attackers who gain access to unmonitored systems can disrupt critical building functions and cripple operations.
Honeywell’s Cyber Insights is an OT-focused solution designed to help provide building operators with near real-time visibility into their full asset landscape. It delivers the comprehensive asset discovery and management that is essential for protecting OT environments in 2025 and beyond.
4: AI’s role in security will grow
In 2025, there will be greater reliance on AI-powered solutions to enhance cybersecurity capabilities. For example, in the building operations space, AI can be used to automate patch management and mitigate disruptions. Instead of simply deploying patches, AI can analyze the risks and impacts, and selectively apply patch updates in a way that minimizes downtime.
AI is also enhancing security monitoring and incident response. For example, AI can help in analyzing log data to quickly identify true threats and prioritize the most critical issues. This allows organizations to eliminate false positives and respond to incidents faster and more effectively.
5: OT security expertise will be in demand
As cyberattacks are increasingly targeted at OT systems, organizations are recognizing the critical need for security teams to deeply understand OT infrastructure and its unique vulnerabilities. Traditional IT personnel often lack the specialized knowledge required to secure OT assets like HVAC, access control and building management systems.
Going forward, security leaders must make sure that their teams can identify and mitigate risks across the full IT-OT convergence. This includes understanding OT communication protocols, equipment architectures and the potential cascading impacts of disruptions. Without comprehensive OT security expertise, organizations remain dangerously exposed to attacks that could cripple critical systems and operations.
