Ready or not, 2025 is here.

This year’s cybersecurity landscape is shaping up to embrace resilience and innovation while learning from past challenges. Experts agree — organizations need significant shifts in strategy and mindset to tackle what’s next.

We’ve rounded up 2025 cyber predictions from industry leaders to help you prepare for what’s around the corner.

Here’s what you need to know.

1. Zero Trust is the gold standard

For years, Zero Trust has been hailed as the future of cybersecurity. But experts see 2025 marking its evolution into the universal cybersecurity standard.  

John Kindervag first published on Zero Trust over a decade ago. Now, Zero Trust is recognized as the North Star for cybersecurity strategies.

“Organizations worldwide will increasingly adopt Zero Trust principles to enhance their security frameworks,” Kindervag says. “This strategic shift is driven by the need to effectively combat advanced, persistent threats that jeopardize national security.”

Trevor Dearing, Illumio’s director of critical infrastructure, agrees. He predicts a rapid shift toward Zero Trust in operational technology (OT) environments in particular.  

“OT environments will begin to look a lot more like IT environments,” he says. He believes traditional architectures will continue to get replaced with a modern Zero Trust approach. This will drive both operational and cyber resilience.

2. Breach containment replaces prevention as the top priority

From the MOVEit attacks to the U.S. telecoms hack, organizations across the globe faced an escalating wave of cyber incidents. Now more than ever, it’s clear that breaches aren’t a matter of if but when.  

In response, experts expect organizations to make major progress on shifting from a prevention-focused security approach to a breach containment approach in 2025.

“Organizations are spending increasing time, money, and resources on prevention and detection technologies like EDR – and yet they’re still getting breached,” says Dearing. “The focus will move toward a breach containment strategy that emphasizes resilience and continuity.”

This means developing detailed recovery protocols, mapping minimum viable operations, and prioritizing rapid response measures. As Dearing puts it, the question will no longer be, “How do we prevent this?” but rather, “How fast can we recover?”

3. Artificial intelligence: Friend, frenemy, or foe?

Artificial intelligence (AI) will be both a powerful ally and a growing risk in 2025. While AI-driven technologies will bolster real-time threat detection, attackers are already finding ways to exploit them.

“In 2025, artificial intelligence and machine learning technologies will be pivotal to enhancing Zero Trust environments,” says Kindervag.

These tools will help organizations detect, contain, and respond to threats faster than ever before, giving defenders an edge over increasingly sophisticated adversaries.

However, Michael Adjei, Illumio’s director of systems engineering, warns that attackers will target AI supply chains. “They will seek out the sources, namely providers of GenAI tools and copilots,” he says. He predicts breaches involving AI technology companies as cybercriminals exploit vulnerabilities that expose customer data.

Adjei also cautions that social engineering tactics will evolve faster than they have in the past. Users will fall into highly customized scams created with AI and inadvertently trigger breaches. “Ordinary users will, in effect, become unwitting participants in mass attacks in 2025,” he says.

4. Critical infrastructure risks increase

The stakes for critical infrastructure have never been higher. A major cyberattack in 2025 could force governments and critical industries to rethink resilience strategies for essential services.

“The world continues to hang by a thread when it comes to combatting cyberattacks,” says Dearing. “A major attack on CNI (critical national infrastructure) like energy could cripple essential services and halt basic operations for days.”  

According to Dearing, such an event would prompt unprecedented public disruptions and potentially lead to new compliance mandates.  

Gary Barlet, Federal CTO at Illumio, emphasizes the need for urgency in protecting infrastructure. “Critical infrastructure sectors will need to accelerate cybersecurity efforts, prioritizing ‘assume breach’ principles as they face intensifying geopolitical cyber threats,” he says. By focusing on segmentation, threat detection, and rapid incident response, sectors like utilities, transportation, healthcare, and government can better withstand attacks.

5. Cybersecurity investment gets serious

As cybersecurity rises to the top of the boardroom agenda, leaders will shift their focus from flashy security tools to actionable investments. This evolution reflects a growing demand for substance over optics in cybersecurity.

“2025 will be the year when we finally see this shift from awareness to accountability,” says Raghu Nandakumara, Illumio’s senior director of industry solutions.  

He expects business leaders will emulate figures like Satya Nadella, CEO of Microsoft, to take ownership of cybersecurity rather than placing all responsibility on security and IT teams.

Organizations will also reevaluate spending priorities. “Security budgets will continue to rise, but we’ll see less investment in fashionable technologies like NDR and SOAR,” says Nandakumara. Instead, the emphasis will shift to solutions that reduce the impact of breaches and protect critical assets.

6. Goodbye CISOs. Hello CSOs.

The changing cybersecurity landscape is also reshaping leadership roles. In 2025, the traditional Chief Information Security Officer (CISO) may be replaced by the broader Chief Security Officer (CSO) role.

“Organizations recognize that threats are no longer siloed in separate areas of the business,” says Nandakumara. “They require a leader who can unify all risks and provide comprehensive oversight of security.”

The CSO will ensure that cybersecurity is addressed holistically across the organization. Nandakumara believes CSOs will sit on the executive team and board. This ensures that the leadership is not only aware of cybersecurity issues but is also accountable for security-related decisions and strategies.

Are you ready for what 2025 has in store?

2025 will bring its share of challenges. But it also offers a chance to redefine how we approach cybersecurity.

As the experts remind us, the future of cybersecurity isn’t about avoiding every attack. It’s about how well we recover, adapt, and thrive in the face of constant challenges.

Organizations that embrace Zero Trust as a strategic priority will be better positioned to not only be resilient against threats but also innovate with confidence. With a Zero Trust approach, you’re not just reacting. You’re prepared for whatever comes next.
