In the modern age of remote work and convenience is king, excessive network permissions exist in most organizations. People have unnecessary access to numerous resources, and as a result of this – what we call network openness – it’s easy for attackers to move laterally and take over. 

Enter microsegmentation: a simple concept of taking the network from one large environment and breaking it into smaller isolated segments, allowing you to gain granular control over network traffic and access. It’s typically implemented using firewalls either on the host or physical hardware, or software defined networking to limit where traffic is routed to and from – which is complex. 

For those and many more reasons, microsegmentation is difficult to maintain and scale. Zero Networks has made it simple and achievable, as we shared on this webinar. Read on for key takeaways and access the full on-demand webinar below.  

Some of the key takeaways: 

  1. Traditional microsegmentation can be costly; projects typically take years and manually defining rules is human intensive. Plus, it’s easy to break applications or access while implementing microsegmentation manually. On the other hand, Zero Networks deploys a virtual appliance that allows us to connect to each host operating system firewall and automatically build your microsegmentation rules during a learning period. Combined with just-in-time MFA for privileged access, Zero Networks is a one-click, complete network security solution that’s (almost) too good to be true.  
  1. Aaron J. Goodwin, CISO of B. Riley Financial, shared how Zero Networks took a very painstaking, human-intensive process and automated it, completing it in a much quicker timeframe. It also helped them understand their internal systems – and the openness within those networks – and subsequently reduced the amount of traffic throughout the network. With Zero Networks, they were finally able to successfully stop an automated penetration testing system that the company had been struggling to pass completely for years. Now, they get alerted to potential threats but at the same time, it’s taken care of for them. 
  1. Some best practices for microsegmentation include: 
    • Identifying critical assets 
    • Implementing least privilege 
    • Using multiple layers of security 
    • Monitoring and auditing continuously 
    • Automation and orchestration to improve efficiency and scalability 
    • Regularly reviewing and updating policies and configurations 
    • Being aware of the impact of microsegmentation
