Vulnerability scanners typically come in two variants: local or remote. With the first group, the scanning itself happens on the related device itself. While this requires direct access to the system or device, it often results in a more extensive scan. Remote scanning is commonly used, where the scan happens on a central system. Some vulnerability scanners may be configured to do a hybrid: network-based scanning combined with an authenticated scan to obtain more details.
Vulnerability scanners are typically used for vulnerability management and vulnerability scanning.
Users for these tools include pentesters, security professionals, system administrators.
Some of the vulnerability scanners have features that make them stand out among the others. If one of these characteristics are important to you, have a look at these selected tools first.
Popular vulnerability scanners

The main reasons to use Dagda is the detection of vulnerable or malicious components within your containerized environment.
Intrigue Core (attack surface discovery)
OSINT research, asset discovery, attack surface measurement, intelligence gathering, penetration testing, security assessment
Intrigue Core provides a framework to measure the attack surface of an environment. This includes discovering infrastructure and applications, performing security research, and doing vulnerability discovery.
Intrigue also allows enriching available data and perform OSINT research (open source intelligence). The related scans include DNS subdomain brute-forcing, email harvesting, IP geolocation, port scanning, and using public search engines like Censys, Shodan, and Bing.
JexBoss (JBoss verify and exploitation tool)
application security, application testing, penetration testing, vulnerability scanning
JexBoss is a security tool to verify and exploit vulnerabilities in JBoss applications. It can be used for security assignments and pentests.
Lynis (security scanner and compliance auditing tool)
IT audit, penetration testing, security assessment, system hardening, vulnerability scanning
Lynis can detect vulnerabilities and configuration flaws. Where a typical vulnerability scanner will just point out vulnerabilities, Lynis aims for an in-depth audit and continuous improvement. For this reason, it needs to be executed on the host system itself. By seeing the system from the inside out, it can provide more specific details than the average vulnerability scanner.
Nmap (network and vulnerability scanner)
network scanning, vulnerability scanning
Nmap is a security scanner that can perform a port scan, network exploration, and determine vulnerabilities
OpenVAS (vulnerability scanner)
penetration testing, security assessment, vulnerability scanning
OpenVAS is a framework of several services and tools offering a vulnerability scanning and vulnerability management solution.
Prowler (vuln) (distributed vulnerability scanner)
security assessment, vulnerability scanning, vulnerability testing
A vulnerability scanner like Prowler can be used to scan the network for vulnerabilities. Prowler can perform active network scanning and uses fingerprinting. Part of the process it to test for default or weak credentials.
Safety (vulnerability scanner for software dependencies)
penetration testing, security assessment, security monitoring, vulnerability scanning
When having applications deployed in your environment, not all of those may be installed via a package manager. When your infrastructure grows, it becomes even harder to know which tools are properly patched and which ones are not. For Python applications, this is where Safety comes in that can help scan installed software components via pip. It will also look at any of the dependencies that are installed.
Tulpar (web vulnerability scanner)
application security, application testing, web application analysis
Tulpar is a vulnerability scanner that can be used to test new or existing web applications. In the former case, it could be helpful to test a new project before it is deployed into production. This could be done by the developer or a security professional. If some web application is already in production, then it might be a good tool to perform regular testing on known vulnerabilities. In this case, it is typically a pentester or security specialist that does the testing.
VScan (vulnerability scanner with Nmap and NSE)
backdoor detection, vulnerability scanning
Vscan is a security tool to perform vulnerability scanning with Nmap. It leverages NSE scripts to provide some flexibility in terms of vulnerability detection and exploitation.
Vane (WordPress vulnerability scanner)
application security, web application analysis
Vane is a forked project of the now non-free popular WordPress vulnerability scanner WPScan.
Vuls (agentless vulnerability scanner)
system hardening, vulnerability scanning
Vuls is a vulnerability scanner for Linux and FreeBSD. It is written in Go, agentless, and can use a remote login to find any software vulnerabilities. It has multiple levels of scanning, from a fast scan up to a deep scan with extensive analysis.
Wapiti (vulnerability scanner for web applications)
application fuzzing, vulnerability scanning, web application analysis
Wapiti is typically used to audit web applications.
Whitewidow (SQL vulnerability scanner)
application security, penetration testing, vulnerability scanning
Whitewidow is a security tool to perform automated SQL vulnerability scans. It can be used during penetration tests or for security assessments.
Yasuo (vulnerability scanner for web applications)
penetration testing, vulnerability scanning, web application analysis
Yasuo is a Ruby script that scans for vulnerable and exploitable third-party web applications. There are many remotely exploitable vulnerabilities for web applications and their front-end components. Yasuo helps to make it easier to scan for the weaknesses like remote code execution (RCE), SQL injections, and file inclusions.
arch-audit (detection of vulnerable packages on Arch Linux)
software management, vulnerability scanning
Arch-audit is a small utility that scans the system for known vulnerabilities on Arch Linux. It can be used by users of the Linux distribution to know when to update and what packages have weaknesses. With Arch Linux being a rolling distribution, this may improve the interval or timing of software patching.
