GenAI and Agentic Systems: Reshaping the Security Stack

Cybersecurity stands at a major inflection point. For years, security operations relied on traditional tools such as manual playbooks, rule-based systems, and an army of overstretched analysts. But as threats evolve faster than humans can respond, that old playbook no longer works.

Today’s security leaders—the CISOs, IT heads, and operations teams—are facing an avalanche of threats that are smarter, quicker, and more unpredictable than ever before. At the same time, compliance pressure is intensifying, talent remains scarce, and the sheer volume of data continues to explode.

According to the World Economic Forum’s 2025 Global Cybersecurity Outlook, only 20% of Asia-Pacific respondents reported confidence in handling major cyberattacks on critical infrastructure. A high percentage of 60% felt neutral. We see that the region is not as ready as it should be.

Understanding GenAI vs. Agentic AI

We have heard a lot about GenAI (Generative Artficial Intelligence) lately, from helping generate dynamic incident reports and threat summaries, to response scripts, or even attack simulation scenarios.

But the real game-changer is agentic artificial intelligence (AI). Where GenAI is about content generation, agentic AI is a virtual analyst that can assess a situation, reason through context, and execute the right action automatically. Whether it is autonomous threat hunting, real-time containment, or intelligent query generation, agentic AI is designed to behave like a seasoned security pro.

And that is the crucial point. Together, GenAI and agentic AI are redefining the role of Security Operations Centres (SOCs). They are no longer just tools in the hands of analysts, they are becoming strategic partners.

Why Security Needs an Upgrade

On the other side of the fault line are cybercriminals using AI. They develop deepfakes, automate phishing campaigns, and build more sophisticated malware that is deployed at lightning speed. Security teams are often stuck playing catch-up, trying to keep pace with threats that now evolve in real time.

On top of that, Security Operations Centres (SOCs) are facing severe analyst burnout. Alert fatigue is a daily struggle as teams drown in repetitive tasks and constant false positives. Regulations are adding even more pressure, demanding faster reporting, better transparency, and tighter control across the board.

But real-world adoption is already underway. In a recent study commissioned by SentinelOne, 96% of SOC teams said they believe AI can improve their efficiency. Nearly 70% plan to increase spending on AI-powered security tools.

Use cases are growing fast, too. From AI-assisted threat intelligence, to automated query writing, and workflow orchestration, early adopters are seeing measurable improvements in both response time and threat coverage.

What Security Teams Really Need

Security teams may be excited about AI, but they are not adopting it blindly. According to the same study, 88% of organisations would not even consider an AI solution unless it integrates seamlessly into their existing workflows.

What they are looking for is AI that responds in real time, because in the heat of a breach, every second counts. They need context-aware insights that adapt to changing environments, and deliver intelligence that makes sense in the moment.

Crucially, AI must support human-in-the-loop oversight, acting as a co-pilot and ensuring analysts are in control. In an era of heightened compliance and regulation, privacy is paramount. Organisations want assurances that AI systems would not train on, or leak, their sensitive internal data.

Perhaps the biggest irritation is what many call “AI-washing.” It is where vendors dress up basic automation as something more intelligent. Over half of security professionals (55%) say this kind of overhyped marketing makes it harder to evaluate solutions. It is no surprise CISOs are demanding transparency. They want AI that is trained on security, and built by experts.

The Benefits AI Brings to the Modern CISO’s Agenda

Done right, GenAI and agentic systems can transform how CISOs operate. This is not about automating jobs away, but about enhancing human capability, giving CISOs and their teams the tools to be faster, sharper, and strategic.

AI is already proving its worth. Security operations are seeing dramatic improvements, with some organisations reporting a 91% reduction in mean time to incident response, and a 90% increase in automation. That is a shift in how quickly and confidently teams can neutralise threats. Operational costs are also taking a welcome dip, dropping by as much as 66%, while data retention costs have been slashed in half.

What is more, AI helps reduce analyst fatigue, improves SOC productivity, and makes board-level reporting easier, with GenAI generating executive-friendly summaries that do not lose nuance.

From Firefighters to Futurists

The role of the CISO is changing. No longer just the last line of defence, today’s security leaders are becoming strategists who can turn cybersecurity from a cost centre into a competitive differentiator.

GenAI and agentic AI are key to this shift. With tools like SentinelOne’s Purple AI®, SOCs can go beyond scripting prompts to engage with an intelligent partner trained on real-world threat scenarios. Purple AI does not just summarise alerts, it reasons, decides, and acts based on deep security context.

It helps teams focus on what matters, such as proactive defence, strategic planning, and staying ahead of attackers.

Toward Autonomous SOC

A fully autonomous SOC is a journey, and most organisations are still in the early to mid-stages. By gradually shifting repetitive tasks to AI, and reserving human expertise for complex judgement and strategy, SOCs can become more agile, adaptive, and prepared.

AI will not replace analysts. However, analysts who use AI will be the ones that ultimately give themselves the edge over threat actors. With GenAI and agentic AI at the core of the modern security stack, the future of cybersecurity is faster, stronger, and more human than ever.
