Get the Most out of Your Security Appliance with Multi-Instance

03 Sep 2020 by SonicWall

Most enterprises, colleges and universities, government agencies and MSSPs have deployed a number of stand-alone appliances to segment and secure different departments, data centers and customers over the years. Even though this type of deployment offers needed security, it creates operational and management complexities. In order to improve operational efficiency while dealing with constant changes to IT and network infrastructure, security professionals need to look at more efficient ways to deploy security appliances.

To help our customers increase efficiency and get most out of their security appliances, SonicWall has added multi-instance capability to our latest NSsp 15700 high-end firewall. Here’s how our newest feature will work, and how it compares with its predecessors.

Traditional way of doing things: Multi-tenant

Apart from deploying multiple standalone appliances to achieve segmentation and secure different entities, customers can also use multi-tenant technology. Multi-tenant allows security professionals to logically segment one instance into multiple virtual firewalls on a single security appliance. Those virtual firewalls will share the same physical resources available on the security appliance, such as CPU, memory, and interfaces. Although this method allows improved operational efficiency and the ability to deploy more than one firewall on a single security appliance, it has some limitations:

- Virtual firewalls need to have the same software version installed — they cannot have independent versions
- Potential for hardware resource starvation if one of the logical firewalls is oversubscribed 
- Firewall management tenant is shared, leading to configuration limitations
