Tenable Security Center and NodeZero Platform by Horizon3.ai compete in the cybersecurity space. NodeZero seems to have the upper hand due to its ease of deployment and comprehensive vulnerability management features.
Features: Tenable Security Center offers vulnerability scanning, dashboard reporting, and a distributed scan model suited for large IT infrastructures. NodeZero Platform excels with real-world attack simulations, autonomous operations, and vulnerability reporting with direct links to patches, enhancing its competitive edge.
Room for Improvement: Tenable Security Center could improve its query engine flexibility, tool integration, and reporting customization. NodeZero Platform would benefit from greater integration with cybersecurity tools and faster scanning speeds in real-world scenarios.
Ease of Deployment and Customer Service: Tenable Security Center provides robust on-premises deployment options but requires significant initial setup. It has responsive customer service, albeit with occasional slow response times. NodeZero Platform offers flexible cloud and hybrid deployment options, and its technical support team is responsive, though it continues to improve.
Pricing and ROI: Tenable Security Center is seen as expensive, particularly for smaller organizations, but it offers significant ROI in terms of reduced manpower and improved security. NodeZero Platform is competitively priced, offering cost savings with flexible licensing compared to traditional penetration tests, despite higher upfront costs associated with Tenable.
