Network security is any activity designed to protect the usability and integrity of your network and data. It includes both hardware and software technologies It targets a variety of threats It stops them from entering or spreading on your network Effective network security manages access to the network.

How does network security work?

Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats.

How do I benefit from network security?

Digitization has transformed our world. How we live, work, play, and learn have all changed. Every organization that wants to deliver the services that customers and employees demand must protect its network. Network security also helps you protect proprietary information from attack. Ultimately it protects your reputation.

1. Access control

Not every user should have access to your network. To keep out potential attackers, you need to recognize each user and each device. Then you can enforce your security policies. You can block noncompliant endpoint devices or give them only limited access. This process is network access control (NAC).

2. Antivirus and antimalware software

"Malware," short for "malicious software," includes viruses, worms, Trojans, ransomware, and spyware. Sometimes malware will infect a network but lie dormant for days or even weeks. The best antimalware programs not only scan for malware upon entry, but also continuously track files afterward to find anomalies, remove malware, and fix damage.

3. Firewalls

Firewalls put up a barrier between your trusted internal network and untrusted outside networks, such as the Internet. They use a set of defined rules to allow or block traffic. A firewall can be hardware, software, or both. We offers unified threat management (UTM) devices and threat-focused next-generation firewalls.

4. Data loss prevention

Organizations must make sure that their staff does not send sensitive information outside the network. Data loss prevention, or DLP, technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner.

5. Cloud Security

More and more applications, data, and identities are moving to the cloud to take advantage of cost savings, scalability, and accessibility. Businesses embrace SaaS applications providing employees more control over the applications they use, and how information is shared both inside and outside the office. And because sensitive data and applications are no longer restricted behind a firewall, users no longer need to use the VPN in order to get work done. This increased reliance on the cloud has created the need leaves users more likely to get infected with malware because users are connecting directly to the internet, creating gaps in visibility and coverage for IT security professionals who can’t protect what they can’t see. As employees enjoy more flexibility organizations face an increased risk that sensitive data will be inadvertently or maliciously exposed.
