WatchGuard has revealed its top six cybersecurity predictions for 2026, forecasting a year where AI-driven threats, regulatory pressures, and the decline of legacy tools will reshape the security landscape.

Corey Nachreiner, chief security officer at WatchGuard Technologies, emphasises that organisations must prepare for rapid evolution in both attack methods and defensive strategies.

Crypto-ransomware goes extinct 

In 2026, crypto-ransomware will effectively go extinct, as threat actors abandon encryption and focus on data theft and extortion. Organisations have significantly improved their data backup and restoration capabilities, meaning they’re more likely to recover from a traditional crypto-ransomware attack without having to pay the extortion demands.

Instead, cyber criminals simply steal data, threaten to leak it and even report victims to regulators or insurance companies to increase pressure. Encryption no longer pays off; the real leverage will now come from exposure. 

OSS box will leverage AI to defend against supply chain attacks 

If the surge of attacks against open-source package repositories like NPM and PyPI has taught security teams anything, it’s that open source is under siege. It’s a losing battle and traditional security controls, such as tighter authentication and shorter token lifetimes, can’t keep up.

In 2026, open-source package repositories will adopt automated, AI-driven defences to fight back against a growing wave of supply chain attacks. To keep up with this significant and persistent threat, these repositories will become early adopters of automated SOC-style systems for their own applications, enabling them to detect and respond to attacks in real-time. 

CRA reporting needs finally incentivise secure by design principals 

In 2026, the EU Cyber Resilience Act (CRA) will finally become the market force that drives adoption of secure-by-design principles. With the first phase going into effect in September 2026, software manufacturers selling into the EU must report actively exploited vulnerabilities and security incidents within 24 hours. This is the most aggressive reporting requirement yet.

While the initial rollout will likely be chaotic as companies scramble to comply and more of their weaknesses are exposed, it will ultimately create a lasting incentive to build security into products from the start. At the same time, overlapping global regulations will reveal competing frameworks and contradictions, forcing organisations to navigate an increasingly complex web of compliance.  

First breach carried out by autonomous, agentic AI tools in 2026  

In 2025, WatchGuard predicted that multi-modal AI tools would be able to carry out every aspect of the attackers’ cyber kill chain, which proved to be true. 2026 will mark the year AI stops just assisting cybercriminals and starts attacking on its own. From reconnaissance and vulnerability scanning to lateral movement and exfiltration, these autonomous systems can orchestrate an entire breach at machine speed.  

The first end-to-end AI-executed breach will serve as a wake-up call for defenders who have underestimated the speed at which generative and reasoning AIs evolve from tools into operators. The same capabilities that help businesses automate security workflows are being weaponised to outpace them. Organisations must fight fire with fire: only AI-driven defence tools that detect, analyse and remediate at the same velocity as attacker AIs will stand a chance. 

The fall of VPN and remote access tools will lead to the rise of ZTNA 

Traditional Virtual Private Networks (VPNs) and remote access tools are among the top targets for attackers due to the loss, theft, and reuse of credentials, combined with the common lack of multi-factor authentication (MFA). It doesn’t matter how secure VPNs are from a technical perspective; if an attacker can log in as one of your trusted users, the VPN becomes a backdoor giving them access to all your resources by default.

At least one-third of 2026 breaches will be due to weaknesses and misconfigurations in legacy remote access and VPN tools. Threat actors have specifically targeted VPN access ports over the past two years, either stealing users’ credentials or exploiting vulnerabilities in specific VPN products.

As a result, 2026 will also be the year when SMBs begin to operationalise ZTNA tools because it removes the need to expose a potentially vulnerable VPN port to the internet. The ZTNA provider takes ownership of securing the service through their cloud platform, and ZTNA does not give every user access to every internal network. Rather, it allows you to grant individual user groups access to only the internal services they need to perform their jobs, thereby limiting the potential damage. 

AI expertise becomes a required skill for cybersecurity 

It's nearly the dawn of a new era where cyber offense and defence will take place on an AI battleground. Attackers are already experimenting with automated, adaptive and self-learning tools. Defenders who can’t match that level of speed and precision will be outgunned before they know they’re under fire.

To survive, security professionals must go beyond simple understanding of AI toward mastery of its capabilities and harness it to automate detection and response while anticipating the new vulnerabilities it creates. By next year, AI literacy won’t just be a nice addition to a résumé, it’ll be table stakes, with interviewers diving in on practical applications of AI for cyber defence.
