Featured Reviews

Vibin Thomas - PeerSpot reviewer
Technical Team Lead - Content Security at Valuepoint Systems
Zero-trust micro-segmentation has strengthened security and improves east-west traffic visibility
While Akamai Guardicore Segmentation is a very powerful solution, there are a few areas where it could be improved. One of the main challenges is the initial deployment and policy design complexity. In large environments, understanding all application dependencies and creating the right policies can take time and requires close coordination with application teams. The user interface and policy management can also be improved. As the number of policies grows, managing and organizing them becomes slightly complex. A more simplified or intuitive policy structure would help operational teams. Another area is integration with other security tools such as SIEM or SOAR platforms. While integration is possible, making it more seamless and easier to configure would add value. Additionally, the reporting and dashboard could be enhanced to provide more customizable and business-level insights, especially for management and reporting. One small improvement I would suggest for Akamai Guardicore Segmentation is having more automation capabilities for policy creation and recommendation. For example, AI-driven suggestions based on observed traffic patterns would help reduce manual effort during the initial policy design. It would also help to have more predefined templates for common use cases, especially for industries such as banking, to speed up deployment. Another area is enhanced reporting customization where we can easily generate business-level dashboards for management and compliance teams without any additional effort.
Brent Hamlin - PeerSpot reviewer
Infrastructure Manager at a construction company with 501-1,000 employees
Continuous threat scanning has improved remediation time and strengthened executive reporting
The best features that The NodeZero Platform by Horizon3.ai offers include the automated scans, which are great to use; you set it, scope it, and let it go, which works really well. The executive reporting feature is impactful for me as a manager, providing a strong foundation to give quarterly and yearly reports to our executives and board to see the state of our infrastructure from a security standpoint. The level of detail and clarity in the executive reports from The NodeZero Platform by Horizon3.ai absolutely helps me communicate effectively with leadership. They are detailed enough for me to extract the necessary information tailored for the executives and to provide a broader perspective on our mitigation efforts or accepted risk stance and where additional controls exist. The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization. It allows us to run scans whenever needed, unlike a single third-party system that only provides a snapshot in time; our processes must be ongoing as the security landscape is dynamic. NodeZero's endpoint security effectiveness feature impacts my understanding of potential security threats by providing a clear picture of both the external and internal landscapes within my organization, enabling me to prioritize and adjust as needed for vulnerabilities such as WordPress plugin issues or user enumerations and software code version assessments. I have built The NodeZero Platform by Horizon3.ai into our weekly and monthly workflows for security CI/CD, and we scan our externally accessible assets every week to address anything quickly if it comes up. That includes our firewalls, websites, and anything that is an external web server, which we scan weekly, while the monthly scans are for internal systems that feed our security CI/CD pipeline, enabling us to action across and prioritize any vulnerabilities caught by The NodeZero Platform by Horizon3.ai.
