Firewall, Secure Web Gateway and Application Delivery Controller with MSS-i

Managed Network Security – the best protection for your business

Protecting the company’s network is one of the fundamental tasks of IT security. It provides the basis for defending against cyber attacks and prevents access to malicious websites and applications.  Managed Network Security covers your network security requirements, reduces system complexity and therefore increases the security, availability and maintainability of your IT systems. 

Fully protected with Network Security Services

Network security today extends far beyond basic perimeter protection. Not only do external attacks have to be fended off, traffic from the corporate network to the Internet has to be monitored and access within the company network has to be managed using network segmentation. The measures also ensure the constant availability of web applications that are accessed over the Internet and prevent service interruptions. MSS/-i’s Network Security Services are provided as a modular package to suit the individual security needs of your company and support your move to a ZTNA (Zero Trust Network Access) and an SASE/SSE (Secure Access Service Edge/Security Service Edge) architecture.

When is it the right solution?

Companies need network security that is tailored to the existing IT system landscape. The measures must both protect access to cloud services and support on-premise resources and thus the IT strategy. Managing network security is key here.

To meet your organisation’s security needs, you need a wide range of scalable network security services that mitigate current threats. These services include:

  • A Next Generation Firewall (NGFW) which, alongside conventional firewall functions, offers extended functionality, such as application-level packet scanning and attack prevention. The latest security features, such as ZTNA or SASE/SSE for hybrid cloud access, can also be integrated.
  • A secure web gateway (proxy) that analyses encrypted connections for malware and blocks access to potentially dangerous Internet addresses.
  • An application delivery controller that ensures the availability and security of web applications through load balancing and access control.
