Tenable Nessus and NodeZero by Horizon3.ai both compete in the vulnerability management category. NodeZero seems to have the upper hand with its AI-driven and autonomous approach, providing active attack capabilities and advanced password-cracking, which makes it especially valuable for offensive security testing.
Features: Tenable Nessus provides comprehensive vulnerability scanning, easy use, and integration flexibility. It is suitable for real-time monitoring and offers extensive reporting options. NodeZero stands out for its autonomous AI-driven approach, active attack capabilities, and intuitive real-time vulnerability assessments, making it a strong choice for offensive security testing.
Room for Improvement: Tenable Nessus users suggest improvements in report generation, integrations, and real-time alerts. Enhancements in cloud security features and credential scanning are also desired. NodeZero could improve its reporting formats and enhance integration with existing security tools, while leveraging GPUs for faster password cracking and better external web app assessments.
Ease of Deployment and Customer Service: Tenable Nessus is often deployed on-premises and is praised for stability and manageability, though some note slow customer support. NodeZero is valued for its easy hybrid deployment, particularly in cloud operations, and its customer service is commended for responsiveness, albeit with minor improvement potential in technical expertise.
Pricing and ROI: Tenable Nessus offers cost-effective solutions for smaller networks with flexible pricing based on IPs. It is considered higher-tier priced, but valued for its feature set. NodeZero is priced competitively against traditional penetration testing with flexible licensing, providing strong ROI by enhancing security postures through different methodologies.
