- Nearly half of 700 surveyed IT and security leaders worldwide admit they cannot contain cyberattacks quickly enough to prevent significant damage.
- The CyberEdge Group report, commissioned by Illumio, spans respondents across North America, Europe, Asia-Pacific, and Latin America.
- The findings expose a dangerous gap between detection capability and containment readiness — two functions enterprises increasingly treat as one.
Detection Is the Easy Part
Nearly half of enterprise security leaders worldwide admit their organizations cannot contain cyberattacks fast enough to stop material damage — even when they detect the threat in real time. That is the headline finding from a sweeping new global study by CyberEdge Group, commissioned by zero-trust segmentation firm Illumio Inc., which surveyed 700 IT and security decision-makers across four major regions.
The data exposes a fundamental flaw in how enterprises have historically invested in cybersecurity. For years, boards and CISOs poured budgets into detection tools — SIEMs, EDR platforms, threat intelligence feeds. The assumption was that spotting an attack quickly equates to stopping it. This report demolishes that assumption with hard numbers.
The Containment Gap Is a Business Risk
Detection without containment is like a fire alarm with no sprinklers. Organizations may know their network is compromised within minutes, yet lateral movement by attackers can propagate across systems in the same window. The CyberEdge study makes clear that speed of detection no longer defines security posture — speed of isolation does.
This gap carries direct financial consequences. Industry data consistently shows that the longer a breach goes uncontained, the higher the remediation cost and regulatory exposure. For enterprises operating in heavily regulated markets — including financial services and healthcare — failure to contain fast enough can trigger mandatory breach notifications and substantial fines.

Zero-Trust Segmentation Moves to the Forefront
The study’s release benefits Illumio directly — the firm sells zero-trust segmentation software designed precisely to limit blast radius when attackers breach a perimeter. But the underlying problem the report identifies is real and widely acknowledged across the security industry. Segmentation, micro-perimeters, and workload isolation are no longer niche concepts — they are becoming baseline requirements for enterprise resilience.
Regional context matters here. Across the Middle East, rapid digital transformation in banking, government, and critical infrastructure has expanded attack surfaces faster than security architectures have matured. The containment gap identified globally is likely more acute in markets where legacy network designs still dominate.
What Security Teams Must Do Now
The report sends a clear signal to CISOs: audit your mean time to contain (MTTC), not just your mean time to detect. Organizations that benchmark only detection speed are measuring the wrong metric. Investment priorities must shift toward network segmentation, automated isolation playbooks, and regular containment simulation exercises — not just more detection layers stacked on top of existing blind spots.
This report is a direct challenge to the detection-first security budgets that dominated enterprise spending for the past decade. For fintech operators and financial institutions across the Gulf — where a single uncontained breach can trigger CBUAE or DFSA regulatory action — closing the containment gap is no longer a roadmap item, it is an immediate board-level obligation. Vendors offering segmentation and automated lateral-movement blocking should expect accelerated procurement cycles across the region in the next 12 months.
