Building a Cyber-Resilient Enterprise: A 2025 Cybersecurity Checklist

As a CIO or IT leader in 2025, you’re already acutely aware of the cybersecurity challenges your organization faces. You don’t need another article telling you that threats are increasing or that security matters.

What you need are actionable insights that help you address specific infrastructure challenges that might be undermining your carefully crafted security strategy.

We work with technology leaders across all industries. We hear the same thing from all of them: The security landscape has fundamentally shifted, and they need guidance to keep up.

This checklist can help you gut-check your posture and adjust to keep your enterprise safe.

Reality Check: What’s Really Changed in Enterprise Security?

The most significant change isn’t in the threats themselves – it’s in their scale, sophistication, and the infrastructure needed to combat them effectively.

• AI has democratized advanced attacks. The barrier to executing complex attacks has collapsed. Tools that required nation-state resources 18 months ago are now available to common threat actors through AI-as-a-service platforms. This isn’t theoretical – security teams report seeing attacks that adapt in real time to defense measures.
• The security perimeter has dissolved. With hybrid work models now permanent, your enterprise boundary has essentially disappeared. Every home office, airport lounge, and coffee shop is now part of your network perimeter. This distribution creates unprecedented challenges for visibility, control, and consistent security policy enforcement. One study found that 61% of companies surveyed reported a third-party breach.
• Infrastructure has become the bottleneck. As you’ve implemented advanced security measures – from real-time monitoring to AI-based threat detection – you’ve likely encountered an uncomfortable truth: your network infrastructure is becoming the limiting factor in your security operations. Low-latency threat response requires high-performance connectivity from the edge to the core.

5 Steps You Can Take to Enhance Security

1. Reassess your security foundation.

Most enterprises have built their security environments on network foundations designed for a different era. Before adding more security tools, evaluate whether your infrastructure can support modern security demands.

• Address performance limitations: A single Endpoint Detection and Response (EDR) solution generates 500MB of data per endpoint daily. Without a high-performance network, these massive data flows become bottlenecks, slowing down security operations and response times.
• Identify infrastructure vulnerabilities: Shared connections and unencrypted data paths expose enterprises to unnecessary risks. Even the most advanced security measures can be undermined by weak underlying infrastructure.

2. Implement Zero-Trust.

Zero Trust has moved from buzzword to necessity, but implementation challenges remain. The right infrastructure determines whether Zero Trust strengthens security or disrupts business operations.

• Enable smart authentication: Strong security doesn’t have to slow down workflows. Continuous verification processes should maintain security without creating frustrating login bottlenecks that hinder productivity.
• Use performance-first implementation: Zero Trust must enhance, not degrade, performance. High-throughput, low-latency connectivity ensures that identity verification, segmentation, and policy enforcement happen in real time.

3. Enable AI-powered security at scale.

AI is transforming cybersecurity, but using AI effectively requires infrastructure that can handle intensive computational workloads.

• Deploy real-time analytics and response: AI-powered security requires processing security telemetry in real-time and automatically containing threats before human intervention is needed. Slow or congested networks limit AI’s ability to react instantly.
• Build Infrastructure for AI operations: AI-based security solutions depend on high-speed, high-capacity networks to handle massive data transfers. Without robust connectivity, AI-driven threat detection becomes unreliable.

4. Secure your expanding edge.

Security must remain consistent as enterprises expand computing resources across data centers, cloud environments, and edge locations. According to Accenture, cloud attacks have increased 75% in the past year, making a secure edge infrastructure more critical than ever.

• Deploy consistent security controls: A fragmented network creates gaps in security coverage. Ensure uniform security policies across on-premises, cloud, and remote environments.
• Ensure redundant, high-performance connectivity: Security at the edge is only as strong as the network behind it. Reliable, high-speed fiber connectivity ensures continuous protection and threat visibility across all locations.

5. Build your business case

Cybersecurity isn’t just about risk management – it’s about protecting your organization’s financial health and operational resilience. Security leaders must effectively communicate why investing in the right infrastructure drives business value.

• Show the cost of inaction: According to IBM data, a security breach linked to a third-party vendor costs enterprises an average of $4.88 million. Downtime is one cost, and regulator fines are yet another. This year alone, federal regulators fined Warby Parker $1.5 million for mishandling HIPAA-protected customer data.
• Connect security to business outcomes: Cybersecurity investments aren’t just a cost center – they’re a competitive advantage. Secure, high-performance networks enable faster innovation, regulatory compliance, and customer trust.
