Network Security with Reduced Complexity and Advanced Threat Protection

Next-Generation Firewalls (NGFWs) are foundational to securing hybrid environments (on-premise/data centre, cloud, SaaS) and providing advance threat protection against malware and intrusions. NGFWs are explicitly designed to include application control, intrusion preventions systems, anti-malware, deep pack inspection and many other network security features that’s required to tackle today’s cyber threats. Clavister has been a pioneer in network security, from launching one of the first firewalls 25 years back to developing fastest virtualised firewalls to integrating network security with secure SD-WAN and SASE. From small to medium businesses (SMBs), to large enterprises, data centres and mobile operators – we offer NGFWs to suit every organisation’s requirements.
