Overview of Tenable Nessus
Company Information
Tenable Network Security, established in 2002 in Columbia, Maryland, is a cybersecurity solutions provider offering vulnerability assessment services with offices in Ireland, France, the United Kingdom, Singapore, and Japan.
Ownership and Financial Track
Initially a privately held company backed by Accel Partners and The Carlyle Group, Tenable went public in July 2018 and is listed on NASDAQ under the ticker symbol TENB.
Recent Changes to Nessus
The free Essentials tier was significantly restricted: scannable targets were reduced from 16 to 5, reporting and export were disabled, plugin updates were delayed by 30 days, and data was not saved at the end of the subscription without upgrading. A new paid “Nessus Essentials Plus” tier was introduced at no cost for verified students and educators. Separately, Terrascan reached end of service on September 30, 2025, and was removed from all Nessus versions. Tenable recommends Tenable Cloud Security for IaC scanning going forward.1
Top Alternatives
Invicti
It automates security tasks within the SDLC, identifies critical vulnerabilities, and integrates remediation workflows. It uses both dynamic and interactive scanning (DAST + IAST) to detect vulnerabilities that other tools may miss, and can be deployed on-prem, in public or private clouds, or in hybrid environments. It also includes a Web Application Firewall and OAuth 2.0 integration.
Pros
- Detailed vulnerability scans with remediation guidance, supporting complex web application architectures with a low false positive/negative rate
- Multiple concurrent scans, predefined scan policies, and detailed scan reports
- Fast support team, intuitive interface, and customizable security checks and scan profiles
Cons
- URL-based licensing is strict; retrieving a license after mistakes is difficult
- Lacks support for 2FA or MFA applications and struggles with certain authentication mechanisms, particularly PKI infrastructures
- Significant resource consumption during scans, causing system slowdowns on larger web applications

Burp Suite is a security testing platform for web applications combining automated and manual DAST, extended with Out-of-band Application Security Testing (OAST). It is available in Professional, Enterprise, and Community editions, each targeting different operational scales.
Burp Suite introduced a Discover tab for attack-surface visibility, faster command-palette navigation, improved SQL injection detection, and SPNEGO support for NTLM authentication. Version 2026.2 added Organizer collections with secure, encrypted sharing and a split request/response view in Intruder. Version 2026.3 introduced support for custom CA certificates and host-level SOCKS proxy bypass. The platform also supports OWASP Top 10:2025 reporting.2
Pros
- Comprehensive toolset for web application security testing covering both manual and automated workflows
- Customizable and extensible, integrating into varied security testing environments
- An active community and frequent updates that keep pace with evolving threats
Cons
- Steep learning curve for users unfamiliar with advanced security tools
- High cost of the Professional Edition, limiting accessibility for smaller teams
- Significant resource consumption during scans
InsightVM by Rapid7
InsightVM is a vulnerability management platform that identifies risks across IT environments using Rapid7’s vulnerability research, global attacker behavior data, and internet-wide scanning. It integrates with Metasploit to validate potential exploits, and covers cloud, virtual, and container environments.
In February 2026, InsightVM standardized vulnerability prioritization with a new Active Risk Score enriched with real-world threat intelligence and patched. The March 2026 release added a Bulk Export API providing access to up to 3 months of remediation data for compliance reporting and up to 13 months of historical trend analysis.3 4
Pros
- InsightVM provides real-time network visibility, integrates with multiple security tools, and supports automated remediation workflows.
- It offers a user-friendly UI, efficient cloud workload management via agent installation, and robust dashboard and reporting capabilities.
- Features such as asset tagging, remediation projects, and effective vulnerability and patch management are highly appreciated by users.
Cons
- Users report that the security console can be buggy, and Jira integration is unreliable
- Vulnerability identification can be slow in large environments, and complex API integration
- Too many false positives leading to unsupported patching instructions
LevelBlue USM Anywhere
In 2024, AT&T Cybersecurity was spun off into a standalone joint venture called LevelBlue. The platform is now marketed as LevelBlue USM Anywhere. AlienVault OSSIM was officially retired in December 2024 and is no longer available for sale.5
LevelBlue USM Anywhere combines asset discovery, vulnerability assessment, intrusion detection, behavioral monitoring, and SIEM in a unified platform. It includes built-in threat intelligence from AT&T Alien Labs and the Open Threat Exchange (OTX) community.
Pros
- Central management, built-in tool connections, and the ability to process large log volumes in real time
- Ease of use, customization, and integrations with AWS, Slack, and other SaaS apps
- Monitoring capabilities, PCI compliance support, and custom alarms and filters
Cons
- USM sensor only allows a single IP for log shipping and lacks auditing for event filtering rule changes
- Vulnerability scanning does not allow closing false positives; the cloud offering lacks log consumption via webhook or API
- The online portal can be sluggish and lacks integration with third-party tools like Jira
SonarQube
SonarQube is a source-available platform that continuously inspects code quality using static analysis to identify bugs, code smells, and security vulnerabilities. The free tier, now called Community Build (renamed from Community Edition in late 2024), is licensed under the Sonar Source-Available License (SSALv1), not an OSI-approved open-source license. Commercial tiers (Developer, Enterprise, Data Center) add branch analysis, taint tracking, AI CodeFix, and compliance reporting.6
SonarQube Server 2026.1 is the current Long-Term Active (LTA) release, adding expanded language coverage Swift 5.9–6.2, Python 3.14, Go, Shell/Bash, and Apex, along with OWASP Top 10 2025 and MISRA C++:2023 compliance rules, Jira Cloud and Slack integrations, and up to 40% faster JavaScript/TypeScript analysis. Version 2026.2 adds Java 25 LTS support and 23 new Apex rules. The platform now supports 35+ programming languages.7
Pros
- Static code analysis across 35+ languages with detailed code coverage reports
- Identifies vulnerabilities and bugs with suggestions for code quality improvements
- Customizable rules with IDE integration and authentication mechanisms
Cons
- Customer support issues and third-party plugin integration complexity for Java code coverage
- UI improvements, faster report generation, and easier custom rule sharing are frequently requested
- CI/CD pipeline integration and automated alerts can be time-consuming to configure
