Featured Reviews

SachinShelar - PeerSpot reviewer
Manager, Account Services Delivery at Softcell Technologies Limited
Micro-segmentation has strengthened zero trust security and reduces lateral movement risks
Some of the best features of Akamai Guardicore Segmentation are its granular micro-segmentation and deep visibility, allowing control to process, service level, and full east-west traffic mapping, while it also stands out for AI-assisted policy creation, real-time threat detection, and software-based enforcement. The feature I rely on most in Akamai Guardicore Segmentation is application dependency mapping and visibility, which gives real-time insight into east-west traffic flows, helping us design accurate policies quickly and troubleshoot issues without impacting production environments. Additionally, Akamai Guardicore Segmentation offers a policy simulation test mode, which is very useful to validate rules before enforcement and avoid outages.

Automated testing has transformed how we deliver fast, consistent security assessments
The key capabilities of the NodeZero platform by Horizon3.ai that I have found most valuable are its speed, scalability, and consistency. It is able to cover a broad scope in a relatively short period of time, which delivers significant efficiency gains when compared with traditional manual testing. It also provides a more consistent outcome, as the process is not influenced by human bias or variability. One of the most valuable features is the ability for security teams to remediate and retest vulnerabilities immediately. The one-click verification capability is particularly effective, as it allows fixes to be validated quickly without the need to rerun the entire assessment. This streamlines the remediation cycle and supports faster confirmation of security improvements. The platform’s real attack capabilities have also helped reduce false positives in the identification of vulnerabilities across our on-premises systems. Because the findings are evidence-based and validated prior to reporting, the results are more reliable and actionable. This enables us to focus our efforts on confirmed security issues that genuinely require attention, rather than spending time investigating theoretical or unverified exposures. The NodeZero platform also strengthens my understanding of potential security threats through its continuously updated capabilities. With new vulnerabilities emerging and being exploited in the wild on a regular basis, it is valuable to have a platform backed by a strong research and development function that continuously updates attack content to reflect the current threat landscape. This makes the platform effective not only as a point-in-time validation tool, but as part of an ongoing and continuous security assurance programme.
