A CISO’s guide to future-proofing security

Setting the stage: Why these conversations matter

In today’s rapidly evolving threat landscape, security leaders are being asked to do more with less. Shrinking budgets, hiring freezes, and reduced access to critical tools are the new reality for CISOs and their teams. Yet, the expectations have never been higher: business resilience, regulatory compliance, and innovation must all move forward often simultaneously.

That’s why I sought out Microsoft’s top security minds during Security Summit Days. My goal was to surface the questions that matter most to CISOs to share actionable insights for navigating uncertainty, driving transformation, and building a future-ready security strategy.

The silo problem: Why integration is non-negotiable

I started by asking: What’s the biggest challenge facing security leaders today? The answer was unanimous.

“The biggest challenge for leaders is that a lot of products work in silos… We need to focus more on the ecosystem versus these siloed products.”
— Emmanuel Taiwo, Microsoft Senior AI Security Solution Engineer Leader

This resonates with what I’m hearing across the industry. CISOs are expected to manage everything from risk assessments and compliance to incident response and board-level strategy—often with fewer resources and less support1. Integration isn’t optional; it’s the only way to do more with less.

From reactive to proactive: The AI advantage

I pressed the team on how organizations can shift from a reactive to a proactive security posture. The consensus? AI is a game-changer.

“Leaders have moved from a reactive to a more proactive approach… They want to focus more on a proactive approach to know about a vulnerability and threat before it could happen.”
— Kriti Arora, Microsoft Senior Security & Compliance Solution Engineer

With budgets tight, CISOs are prioritizing high-impact areas like identity management and zero-trust architecture over broader awareness programs2. AI-driven tools like Microsoft 365 Copilot, Defender, and Sentinel help organizations anticipate threats, automate responses, and visualize their entire attack surface—across cloud, hybrid, and on-premises environments.

Data at the center: Know what you’re protecting

With so much data, how do you know what to protect? I challenged the group, and the answer was refreshingly practical:

“First, you need to understand what is the data that is important for your organization. If you don’t have the knowledge, it is very hard to put controls on it.”
— Liliane Scarpari, Microsoft Security Solution Engineer

For CISOs, this means investing in data classification, governance, and compliance, especially as new AI regulations emerge globally. When resources are limited, knowing your “crown jewels” is the only way to focus your defenses where they matter most.

Security is everyone’s job: Building a security-first culture

Who owns security in a modern enterprise? The answer: Everyone.

“I don’t think we could just look at this as an IT professional, a security professional… We have to think about everyone being part of this transformation.”
— Michael Billy, Microsoft Security General Manager

Training, awareness, and inclusive practices are essential. But with CISOs stretched thin, it is more important than ever to empower every employee to play their part.

Real-world impact: What success looks like

I wanted specifics. What does success look like when organizations get this right?

“When you bring [in] Sentinel and you’re able to bring these third party applications into that platform, you have cross correlation across everything—that’s immediate response data. In my experience in industry, that’s unheard of. Usually you’re having to pull this data set, pull that data set, and trying to bring them together. It just doesn’t work. With Sentinel and XDR, you’re getting a full picture of your estate quickly and more effectively. Overall, it’s going to take you a lot less time.”
— Mike Taylor, Microsoft Senior Security Solution Engineer Leader

The bottom line: Integrated, AI-powered security delivers measurable business value—speed, efficiency, and resilience—even when budgets are tight.

Responsible AI and continuous improvement

How do we keep improving? I closed by asking about the future.

“Go back to the core fundamentals, know your estate, know what data you’re trying to protect. Ultimately, as you prepare for AI, you have to ensure that you have those identities. Make sure you have the data classifications established so you’ll be able to quickly move and pivot.” — Mike Taylor, Microsoft Senior Security Solution Engineer Leader

Continuous learning, responsible AI, and transparent governance are non-negotiable for leaders who want to stay ahead.

My takeaways for CISOs, BDMs, and SDMs

If you are leading security, here is what I would tell you after these conversations:

  • Break down silos. Integration is your best defense.
  • Invest in AI. Use it to anticipate, not just react.
  • Know your data. You cannot protect what you do not understand.
  • Empower your people. Security is everyone’s job.
  • Never stop learning. The threat landscape—and the technology—will keep evolving.
