2025 ended with a rare sense of relief in cybersecurity; fewer alarms, faster detections, cleaner containment. But experts are warning that this quiet is deceptive.
Beneath it sits a rapidly expanding attack surface powered by AI adoption, cloud sprawl, and automation moving faster than governance can keep up.
2026 will not only be shaped by more breaches but will be shaped by smarter, AI-assisted breaches, and organizations that don’t adapt their defenses will feel the impact first.
Expert Predictions for 2026
Experts warn, however, that while detection and containment have improved, rapid adoption of AI and cloud technologies without proper governance introduces new vulnerabilities.
Georgie Cohen, IBM UKI Cybersecurity Services Leader, notes:
“The data speaks for itself as organisations implementing robust AI-driven security automation are significantly reducing breach costs. But without governance, risks remain high.” – says a cybersecurity expert at IBM, 2025
1. AI Could Be the #1 Cause of Breaches in 2026
AI is becoming the new “brain” of modern infrastructure, powering detection, automation, decision-making, and entire cloud workflows. But as organisations embed AI deeper into their environments, many are deploying these systems faster than they can secure or govern them.
This gap between AI adoption and AI oversight is exactly why experts warn that AI-driven misconfigurations, shadow AI tools, and exploited AI workflows could become the leading cause of major breaches in 2026.
Sean Atkinson, CISO at CIS, explains:
“As more decision-making is placed on AI technologies, organizations must assess them as tools, technologies, and personas within their environments — each with its own risk profile.”
AI will be operationalized across security operations, automating threat detection, containment, and remediation. While this boosts defensive capabilities, misconfigured AI, unmonitored decision pipelines, and exploited AI agents offer attackers new, high-impact entry points, often invisible to traditional security controls.
2. Companies Without Zero Trust Architecture Will Be More At Risk
Organizations failing to adopt zero-trust policies risk lateral attacks, credential theft, and exposure of sensitive data. Security frameworks will need to combine technical safeguards with policy-driven governance to meet evolving standards.
Lee Noriega, Executive Director at CIS, highlights:
“Beginning in 2026, zero trust architecture (ZTA) will transition from a best practice to a regulatory requirement for public sector organizations.”
3. Supply-Chain Weak Links Will Determine Breach Impact in 2026
Even small breaches in third-party systems can cascade into massive, multi-sector disruptions.
Randy Rose, VP of Security Operations & Intelligence at CIS, warns:
“Adversaries are no longer content with hitting one organization at a time. They’re targeting the connective tissue of our digital ecosystem: software suppliers, managed service providers, and other single points of failure.” (CIS, 2025)
4. Next-Gen Malware Will Move Too Fast for Legacy Security
CIS experts note that crimeware is becoming semi-autonomous:
- Generative AI tools accelerate malware development and obfuscation.
- AI-assisted payloads enable faster lateral movement and credential theft.
- Threat actors exploit cloud and SaaS infrastructure to evade detection.
These developments could shorten the time between initial access and full compromise, making breaches more sophisticated and harder to detect.
5. OT and Public Services Are Poised for High-Impact Breaches in 2026
Healthcare, utilities, and transportation sectors remain high-risk, particularly where federal support is limited, and adversaries target underfunded municipal networks.
Marcus Sachs, SVP & Chief Engineer at CIS, predicts:
“Operational Technology (OT) and critical infrastructure will experience a high-impact cyber incident, likely tied to geopolitical conflicts, triggering mandatory federal cybersecurity standards.” (CIS, 2025)
6. The Human Element Will Still Remain The Weakest Link
Even well-funded organizations struggle with talent shortages, stress on security teams, and operational fatigue.
Valecia Stocchetti, Sr. Cybersecurity Engineer at CIS, emphasizes:
“Security programs must anticipate and adapt to multi-stage attacks. Compliance alone is not enough — building a resilient cybersecurity posture requires a culture of security embedded across the organization.” (CIS, 2025)
What Organizations and Individuals Can Do?
In 2026, cyber threats will no longer be just technical; they’ll exploit human error, misconfigured AI, vulnerable supply chains, and overlooked cloud environments. Staying ahead means being proactive, not reactive. Awareness, governance, and a culture of security will separate resilient organizations from those caught off guard.
Experts consistently recommend:
- Operationalize AI responsibly by deploying AI with robust governance, continuous monitoring, and clear accountability for every automated decision.
- Adopt zero-trust architecture and least-privilege policies: Limit access to only what’s necessary to reduce the blast radius of any potential compromise.
- Secure supply chains and third-party integrations: A single weak vendor can jeopardize the entire organization.
- Continuously monitor cloud, SaaS, and hybrid environments: Detect unusual activity, lateral movement, or misconfigurations before attackers exploit them.
- Embed a security-first culture across teams: Training, awareness, and processes are just as critical as technology in preventing breaches.
For individuals, safeguarding personal and professional data is equally vital. Use encrypted connections, VPNs, and private browsing practices to protect against AI-assisted attacks and cloud-based threats. Simple, consistent practices at the individual level create a critical layer of defense in an increasingly automated and sophisticated threat landscape.
How Can PureVPN Help You From Being a Part of These Breaches?
As AI-driven attacks, supply-chain breaches, and cloud exploitation rise in 2026, your personal digital footprint becomes a direct extension of organizational risk. PureVPN reduces that exposure by encrypting all online activity, masking your IP address, and breaking the metadata trails attackers use for automated profiling and targeting — keeping your connection secure whether you’re on public Wi-Fi, working remotely, or accessing cloud services.
By routing traffic through hardened, monitored servers and minimizing the information attackers can harvest, PureVPN helps ensure you don’t become the easiest entry point in a fast-evolving threat landscape. In a year where breaches will be smarter and faster, maintaining privacy and secure connectivity isn’t optional — it’s a core layer of modern cyber resilience.
Key Takeaways
In 2026, breaches will likely be more sophisticated, fast-moving, and multi-dimensional. While organizations focus on policy, governance, and AI oversight, individuals can reduce risk exposure with tools that safeguard online activity. Encrypted connections, private networks, and careful access controls help maintain security even as threat actors evolve.
Because when attackers are always innovating, staying private online isn’t just a convenience; it’s a crucial part of your personal and professional security strategy.
