When it comes to cyber defense, depth is the name of the game. One barrier isn’t nearly enough anymore. To withstand increasingly sophisticated cyberattacks, network security companies rely on an arsenal of tools that detect, react and protect against cybercrime in real-time.

What Is Network Security?

Network security is the process of protecting a computer network infrastructure from unauthorized access, data breaches, theft and more.

Application security, behavioral analytics, data loss prevention, email security and VPN tools are just the tip of the iceberg. Along with traditional methods of protection, network security companies are also focusing their efforts on developing cloud-based products and IoT devices. By 2025, it’s estimated that there will be 27 billion connected IoT devices. With this expected growth, companies in the space are already augmenting their services to protect our privacy.

We’ve rounded up 16 network security companies using innovation to protect our data.
