How Next15 Scales and Simplifies Cybersecurity Across 23 Brands

Next15 is a London-based business growth consultancy operating more than 23 independent brands across Europe, North America, and Asia. Each brand has its own leadership team, operating model, and technology stack. Some are long-established firms with mature controls in place. Others are fast-moving startups running on lean infrastructure and early-stage security.

For Rob Sugrue, Group Head of Information and Cybersecurity, the challenge was clear: how do you deliver consistent and effective security across a portfolio this diverse without slowing the business down?

Sugrue heads up security for the Next15 group, overseeing strategy, cyber risk management, security operations, and incident response. With limited internal capacity and an expanding footprint, his team needed a solution that could scale quickly, adapt to different environments, and provide full visibility into threats across the entire organization.

“We don’t want to mandate how every brand operates,” Sugrue said. “We needed something that could flex across Google, Microsoft, Mac, and Linux … without getting in the way.”

That’s when Next15 turned to CrowdStrike.

Next15 adopted the AI-native CrowdStrike Falcon® cybersecurity platform to unify endpoint detection and response (EDR) across all brands. The deployment is managed by CrowdStrike Falcon® Complete Next-Gen MDR, CrowdStrike’s fully managed detection and response service, which provides 24/7 elite protection, industry-leading threat detection, and full-cycle remediation delivered by CrowdStrike experts.

The results were immediate. CrowdStrike was quickly deployed across the organization. And whenever Next15 acquires a new company, that process is repeatable and streamlined — ensuring all endpoints are monitored and protected in a matter of hours. For a business growing through frequent acquisitions, that agility makes a measurable difference. 

“If we acquire a company on Monday, we can have CrowdStrike deployed by Monday afternoon,” Sugrue said. “That kind of speed is game-changing.” 

Today, CrowdStrike delivers consistent EDR across every environment at Next15. Whether a brand runs MacBooks and Google Workspace or Windows endpoints in Azure, CrowdStrike ensures every device is protected.

In addition to EDR protection across brands, Next15 gained visibility into phishing attempts, rogue downloads, and user-triggered execution attempts — most of which are stopped automatically before causing disruption. What used to be high-risk events are now routine with Falcon Complete Next-Gen MDR.

“The fire is already out before we even look at the alert,” Sugrue said. “It’s not about how we put it out … it’s about understanding how it started and making sure it doesn’t happen again.” 

Sugrue credits CrowdStrike with enabling a more mature and proactive approach to security. His team no longer spends time chasing false positives or reacting to unmanaged incidents. Instead, they’re focused on raising the group’s overall security posture by establishing frameworks, refining policies, and educating users. 

“CrowdStrike gives us the time to focus on what matters,” he said. “We can be strategic instead of just reactive.”

As Next15 continues to grow, the team plans to expand its use of the Falcon platform to add new protections with minimal overhead. Throughout this evolution, the core benefit remains the same: Confidence. Confidence that no matter how fast the business moves — or how many new brands come on board — every endpoint, user, and asset will be protected from day one.

“CrowdStrike is best of breed,” Sugrue said. “It’s scalable, reliable, and backed by real expertise. That’s what we needed — and that’s what we got.”

For midsized organizations operating across multiple entities or managing growth through M&A, Next15’s experience offers a clear takeaway: Modern cybersecurity doesn’t need to be complex. With the right platform and the right partner, it can be simple, scalable, and effective from day one.
