FAQ
The biggest cyberthreats in 2025 will follow trends in cloud adoption and AI innovation that have characterized recent years. AI-assisted phishing, especially voice phishing (vishing), and ransomware campaigns will likely hit faster and harder, and cloud-hosted data will be the target of increasingly rampant attacks. AI is expected to fuel more attacks embedded in TLS/SSL-encrypted traffic—making these threats even harder to detect and mitigate.
Insider threats will also pose a significant risk, with cybercriminals planting insiders as employees or contractors to exploit legitimate access. At the same time, ransomware is likely to see more encryption-less attacks as threat actors strive to cause minimal disruption while still extorting large payouts.
In 2025, organizations that do not adopt zero trust architecture will be increasingly vulnerable to breaches and ransomware attacks, because traditional castle-and-moat security is ineffective at protecting against evolving threats in the world of cloud and AI. By leveraging zero trust architecture with AI-powered capabilities, organizations can greatly reduce their attack surface, prevent initial compromise, eliminate lateral movement, and stop data loss.
AI has already established itself as a powerful tool for both attackers and defenders, and this trend will continue in 2025. Threat actors will continue to find novel ways to abuse AI, such as highly convincing phishing and deepfakes, as well as launch campaigns faster, at a greater scale, than before. Innovations in AI-powered cybersecurity will meet attackers head-on with intelligent threat detection and response, risk management, and more.
The industries most at risk in 2025 will be those that hold the most valuable, vulnerable data. In particular, we expect to see more attacks on the manufacturing and healthcare industries, as well as the education and energy sectors, all of which have strong ties to critical infrastructure, making them especially vulnerable to ransomware attacks.
2025 will call for greater emphasis on proactive defense strategies. Organizations must prioritize a zero trust architecture, augmented with AI-powered security controls, alongside a culture of security awareness all the way from the board and executive level to individual contributors. Aligning security with strategic planning and innovation will better position organizations to counter emerging threats in 2025 and beyond.
