Network Security Solutions

Secure and strengthen your enterprise with Cloudflare’s integrated network security solutions

Enterprises need unified, layered security solutions that can be applied across all endpoints and users — no matter where they’re located. Cloudflare can help.

Traditional network architecture isn’t built to secure today’s enterprise networks.

As the architecture of enterprise networks continues to evolve, so do the methods by which enterprises secure their users, networks, and data.

With the rise of remote work and the ongoing shift to the cloud, traditional architectures and security appliances — custom-built MPLS networks and an impossible-to-maintain patchwork of hardware boxes and tools — can no longer meet the needs of the modern enterprise, forcing organizations to reevaluate their approach to network security.

Network security challenges
Overly permissive access policies introduce risk

VPNs grant excessive trust to users by default, exposing corporate networks to potential data loss, malicious insider threats, and more.

Sophisticated cyber attacks leave networks vulnerable

As DDoS attacks, ransomware, and other threats increase in sophistication and frequency, enterprises need to employ proactive mitigation strategies.

Artificial chokepoints cause latency

Traditional methods of inspecting traffic and mitigating attacks often result in unwanted performance tradeoffs, slowing down applications and impairing end user experience.

Unmanaged devices are susceptible to phishing and malware

In a BYOD environment, employee devices may be targeted by harmful code disguised as innocuous plugins and software extensions — which can then infect other network devices.

Security teams have poor visibility into network movement

Too many point products make it difficult for IT teams to easily monitor user behavior and respond to threats as they develop.

It's time to move your network perimeter to the edge.

Create and enforce uniform security policies

Replace VPN connections with universal Zero Trust policies that can be applied to all employees and devices, regardless of location.

Get ahead of attacks with ever-improving threat intelligence

Identify malicious traffic patterns from bots, vulnerability exploits, and other attacks, so your network is protected from new and emerging threats as soon as they arise.

Inspect network traffic without performance tradeoffs

Apply advanced and automated mitigation techniques via single-pass inspection, instead of backhauling traffic through scrubbing centers.

Maintain visibility from a single control pane

Manage network access and monitor threats on a unified dashboard — no layering incompatible tools or configuring expensive hardware appliances.

Scale network security as your enterprise grows

Choose a global edge network that seamlessly scales as your business grows, enabling you to mitigate attacks, accelerate traffic, and protect your users from any location.
