Top 6 Vulnerability Scanning Tools

Vulnerability scanning tools identify security weaknesses in networks, applications, and systems. Organizations evaluate these tools based on scanning methods (DAST/IAST/SCA), SIEM integration, deployment options, and pricing. Our analysis covers six tools: two network and host scanners, two web application scanners, one endpoint-based CVE layer, and one SIEM with built-in scanning. Capabilities come from each vendor’s own documentation.

Follow the links to see our rationale and a detailed explanation of the tools below:

The focus of the tools is based on our technical reviewer’s experience. Within each vendor’s section, the AIMultiple team outlined our rationale for this selection.

Invicti dominates the vulnerability scanning search market with around 90-95% share, leaving little room for competitors. NinjaOne holds a distant second at roughly 5-7% with a slight upward trend. LevelBlue USM Anywhere, InsightVM (Nexpose), Tenable Nessus, and PortSwigger Burp Suite all register below 2% with no meaningful movement over the period.

Top vulnerability scanning tools analyzed

NinjaOne runs inside NinjaOne’s endpoint management platform.¹ NinjaOne released it in March 2026 for IT teams that detect and fix vulnerabilities on the devices they manage. Organizations that need IP-range scans or web app tests for audits pair it with a dedicated scanner such as Nessus or InsightVM.

It fits as the continuous CVE layer for devices already under NinjaOne management, not as a scanning replacement.

Capabilities

Scope: Real-time software assessment is documented for Windows endpoints. NinjaOne Patch covers Windows and macOS. Devices outside NinjaOne management depend on imported scan data.

Server-side detection: NinjaOne compares installed software versions with CVE and KEV data on its own servers. There is no scan schedule and no agent load spike on endpoints.

Offline devices: If a new CVE is published while a device is offline, NinjaOne matches it to the device’s last-known software state. The finding is queued for action when the device reconnects.

KEV status next to CVSS: The vulnerability view shows CISA KEV status alongside CVSS scores. Teams can rank actively exploited flaws above high-scoring but unexploited ones.

Imports from other scanners: NinjaOne has importers for Qualys, Tenable, Rapid7, Microsoft Defender, and ConnectSecure, plus a generic CSV importer. A CrowdStrike Spotlight importer is also documented. Imported findings map to managed devices. A finding closes when a newer scan no longer contains it.

Link to patching: Paired with NinjaOne Autonomous Patch Management, Patch Intelligence AI can pause risky patches while stable updates proceed (vendor claim).

Burp Suite is PortSwigger’s web security testing toolkit. It comes in three editions. Community Edition is free and includes the manual tools but no automated scanner. Burp Suite Professional is licensed per user and built for penetration testers. Burp Suite DAST runs scheduled and CI/CD scans across many sites

Capabilities

• Burp Scanner: Burp Scanner is an automated DAST scanner built to replicate the methods of a manual tester. It supports state management and automated logins for complex web apps. It powers scans in the desktop editions and in Burp Suite DAST.
• Out-of-band testing (OAST): Burp Collaborator finds flaws that produce no visible response. Burp sends payloads that point to a Collaborator server and then checks whether the target contacted that server. Burp Scanner runs this automatically. Burp Suite Professional also supports manual Collaborator testing.
• Custom scan checks: BChecks let testers write their own scan checks in a simple text-based language.
• API and client-side coverage: Burp Scanner can test GraphQL APIs. DOM Invader supports testing for DOM-based vulnerabilities.
• Agentic testing: Burp AT delegates testing tasks to agents that work through Burp’s own tools. Per-tool permissions decide what runs without approval, and Burp enforces scope rather than the model.²
• Scope: Burp tests web applications and APIs. It does not scan hosts or network services. Community Edition has no automated scanner.

Invicti is a DAST-first application security platform that grew out of the Netsparker scanner. Its 2025 acquisition of Kondukto added application security posture management (ASPM) to the platform. In April 2026, Invicti added DAST-to-SAST correlation.³ It links a runtime finding to the underlying code and the developer responsible for it. In July 2026, Invicti launched Agentic Pentest, which combines autonomous AI with its DAST engine to run penetration tests.

Capabilities

• Proof-Based Scanning: Invicti confirms findings by exploiting them in a read-only way. For SQL injection, for example, the scanner reads from the database but does not write or delete data. Invicti states that it confirms over 94% of direct-impact vulnerabilities and that confirmed results are 99.98% accurate (vendor claim).
• Heuristic engine: The scanner does not rely on a signature database. Invicti says this lets it detect unknown flaws in custom web applications.
• IAST sensor (Invicti Shark): An optional sensor on the application server reports the exact location of an issue. It also reaches hidden and unlinked pages the crawler cannot find. Invicti advises against installing it on production servers. Invicti’s white paper lists Java, .NET, and PHP sensors.
• Out-of-band detection: Invicti Hawk detects vulnerabilities that respond out of band.
• Incremental scans: Incremental scans test new and changed pages and recheck earlier findings.
• API coverage: Since June 2026, Invicti scans gRPC services from uploaded .proto files.
• Scope: Invicti covers web applications and APIs. It does not scan hosts or network devices.

LevelBlue USM Anywhere (Unified Security Management) is a LevelBlue product. AT&T spun out its cybersecurity business into LevelBlue in 2024, which carries forward the AlienVault assets, including USM Anywhere and the Open Threat Exchange.⁴

LevelBlue USM Anywhere primarily focuses on Security Information and Event Management (SIEM) and does not include integrated capabilities for DAST (Dynamic Application Security Testing), SAST (Static Application Security Testing), or SCA (Software Composition Analysis)​.

Capabilities

• Authenticated host assessment: The USM Anywhere sensor logs in to assets over SSH (Linux) or WinRM (Windows). It then runs host-based checks remotely.
• Standards-based detection: Vulnerability detection is built on SCAP and the OVAL 5.11.2 schema.
• One sensor for logs and scans: The same sensors that collect logs in on-premises and cloud environments also run the scans. Vulnerability data sits in the same console as security events.
• Scan results as SIEM events: Each authenticated scan creates a system event named “Authenticated Asset Scanner Result”.
• Scope: USM Anywhere cannot scan its own sensors. Scans running longer than two hours time out. It has no DAST, SAST, or SCA.

InsightVM by Rapid7 is a vulnerability management tool. It leverages Rapid7’s vulnerability research, global attacker behavior insights, and internet-wide scanning data; it also integrates with Rapid7’s Metasploit for exploit validation.

InsightVM vulnerability data flows into InsightIDR (SIEM) through a platform-native integration on the Rapid7 data mesh, which removes manual setup and keeps vulnerability context consistent across SIEM, MDR, and Incident Command.⁵

Capabilities

• Active Risk score: Active Risk rates vulnerabilities from 0 to 1,000. It combines the latest CVSS score with AttackerKB, Metasploit, ExploitDB, the CISA KEV list, and dark web sources. It also weighs how sensitive the affected asset is.
• Agent and agentless scanning: Teams can trigger an on-demand Insight Agent scan right after patching to confirm the fix.
• Remediation Projects: Security teams group findings into projects and assign them to IT owners.
• Outside-in context: In Exposure Command, Surface Command adds an external attacker view to InsightVM’s internal scan results.
• Deployment: An InsightVM trial remains available for on-premises deployments.
• Scope: InsightVM scans hosts and infrastructure. Web application scanning is a separate product (InsightAppSec).

Tenable Nessus is a network vulnerability scanner sold in three editions. Nessus Essentials is free for up to 16 IP addresses. Nessus Professional is a single-scanner license with unlimited IP scanning. Nessus Expert adds coverage beyond internal hosts. Both paid editions run as standalone scanners. Agent management and multi-scanner dashboards require Tenable One Vulnerability Management, formerly Tenable Vulnerability Management.

For web app scanner pricing, see our DAST pricing comparison.

Capabilities

• Live Results: After each plugin update, Nessus checks existing scan history against the new plugins without a new scan. A follow-up scan then confirms the finding.
• Prioritization inputs: Findings can be ranked by EPSS, CVSS, and Tenable’s VPR score.
• Templates and compliance audits: Nessus ships with more than 450 preconfigured templates. It audits configurations against CIS benchmarks.
• Portability: Nessus runs on many platforms, including Raspberry Pi.
• Nessus Expert additions: Expert adds DAST scanning for web applications and external attack surface discovery. The discovery covers up to five domains and their subdomains.
• Scope: Nessus Professional is a single standalone scanner. Web app scanning and external discovery require Nessus Expert.

Core features of vulnerability scanning tools

• Asset discovery: Finds hosts, services, containers, and web endpoints before scanning, so unmanaged assets do not stay invisible.
• Authenticated scanning: Logging in to a host or application reveals installed packages and pages behind authentication that an unauthenticated scan misses.
• Vulnerability detection: Version matching against CVE feeds, configuration checks, and active tests that send payloads to the target.
• Prioritization: CVSS gives severity. EPSS estimates exploitation probability, and the CISA KEV list marks flaws already exploited in the wild.
• Remediation workflow: Assigning findings to owners, opening tickets, and closing them when a rescan confirms the fix.
• Reporting and compliance: Scan evidence for PCI DSS, ISO 27001, and similar audits.

How to read the integrations table

• SIEM tools: Scanners send findings to the SIEM. Analysts can then see whether an asset under attack has an open vulnerability.
• WAF: Confirmed web app findings go to a web application firewall, which can block exploit attempts until the code is fixed.
• OAuth 2.0: The scanner can log in to web apps and APIs that use OAuth 2.0, so scans reach pages behind authentication.
• Ticketing tools: Findings open tickets in tools such as Jira or ServiceNow with the affected asset and the recommended fix. Some tools close the ticket when a rescan confirms the fix.
• Deployment: On-premises deployment keeps scan data inside the organization’s network. Cloud deployment removes scanner maintenance.
