Do I need network security tools? 

Yes, network security tools are essential for every organization. They protect your data and devices from unauthorized access and cyber threats. They also help you implement security policies and processes. 

What are the different types of network security tools?

Network security tools range from firewalls and their types, email security tools, and Data Loss Prevention (DLP) tools to Intrusion Protection Systems (IPS). Many platforms combine two or more network security tools to provide a comprehensive solution. 

Where can I use network security?

Network security applies to any network—public, private, and especially cloud networks. Public networks openly connect with the internet, while private networks are available only within companies, though outside users, like remote workers, can access them. 

How can I secure my organization’s network?

Multiple network protection strategies such as security policies, processes, network security tools, and physical hardware help secure your firm’s network. You can also allow role-based access to provide extra-padded security based on your organization’s needs. 

Are network security and cybersecurity the same?

No, they aren’t the same because network security is a subset of cybersecurity. In other words, network security tools and strategies protect only a network and its endpoints, while cybersecurity is more comprehensive and includes physical access controls as well.
