Senior Cyber Security Analyst (SAFe Agile) at a transportation company with 1,001-5,000 employees
Advanced threat detection undermined by issues with blocking
NetWitness Endpoint's blocking feature does not work properly - if there's a malicious process, it's not possible to kill it via a custom rule unless and until it's flagged as malicious. For example, if you put IOCs in the form of hashes, it's not possible to block those IOCs - the system will alert you, but they can't be blocked. In the next release, NetWitness Endpoint should include regular expressions for blocking processes and sub-processes, the ability to block IPs, and scalability and integration with the ServiceNow platform or other ticketing solutions.

Micro segmentation has strengthened zero trust security and isolates production from test environments
The advantages of VMware NSX include its micro-segmentation for internal security at the firewall and VM levels, which is very powerful and helps us comply with complete Zero Trust security models. We are able to achieve this and configure network level virtualization with no dependency on VLANs. Micro-segmentation helps improve our security significantly. We are not totally dependent upon our physical upfront firewall, and it makes sense to configure everything using VMware NSX, leading to multiple improvements in our organization. We moved from traditional networking such as VLANs from the firewall and switches to VMware NSX segmentation. We achieve one firewall per VLAN and can stop lateral movement such as ransomware control. The Zero Trust model is the main functionality and architecture it offers, allowing application isolation, such as having a separate production and test environment. Consistent networking and security policies across different environments have a major and very positive impact on our business operations, allowing us to achieve the security posture we want with compliance and regulations.
