Top 5 Vulnerability Scanners

A vulnerability scanner is software application that assesses security vulnerabilities in networks or host systems and produces a set of scan results. However, because both administrators and attackers can use the same tool for fixing or exploiting a system,
administrators need to conduct a scan and fix problems before an attacker can do the same scan and exploit any vulnerabilities found.

a vulnerability scanner allows early detection and handling of known securityproblems. By employing ongoing security assessments using vulnerability scanners, it is easy to identify security vulnerabilities that may be present in the network, from both the internal and external perspective. A new device or even a new system may be connected to the network without authorisation. A vulnerability scanner can help identify rogue machines, which might endanger overall system and network security. Vulnerability scanner helps to verify the inventory of all devices on the network

. The inventory includes the device type, operating system version and patch level, hardware configurations and other relevant system information. This information is useful in security management and tracking.

Top 5 Vulnerability Scanner’s

1 #. Nessus

The vulnerability scanner features high-speed discovery, configuration auditing, asset profiling, sensitive data discovery and vulnerability analysis of your security posture. Nessus can also be used as a stand-alone scanner but requires a ProfessionalFeed subscription to be used commercially. It now costs $1,200 per year, which still beats many of its competitors. A free “Home Feed” is also available, though it is limited and only licensed for home network use.

2#. Core Impact

Core Impact Professional started life as a pure-play penetration test tool. It was, at the time, the premier product of its type. Today, Impact Pro has a lot of added capability, and touches on both pen testing and vulnerability assessment. For all of that evolution, the product has retained its most beguiling benefit: It is a pen testing tool that works for both old pros and entry-level pen testers. If one has a lot of experience, the tool can do just about anything, including working in tandem with another old favorite, Metasploit, and writing one’s own exploit scripts for identifying zero-day vulnerabilities.

3#. Nexpose

The Nexpose Enterprise Edition appliance from Rapid7 is another tool that has grown into a vastly different product over the years. This latest version we believe is the best yet. This solution has gone from its early days as pretty much just a vulnerability scannerto a full-scale vulnerability management tool. With this appliance, administrators can manage the entire vulnerability lifecycle – from discovery of assets through reporting and mitigation – all from one place. The Nexpose incorporates the ability to run more than 75,000 vulnerability checks against more than 22,000 vulnerabilities across multiple operating systems, databases, web applications and virtual assets throughout the enterprise.

4#. QualysGuard

The QualysGuard Vulnerability Management (VM) solution provides automated auditing and vulnerability management for small to large enterprises. The solution is a private cloud-based software-as-a-service. The easily accessible, web-based design makes it possible to operate the system via a browser from anywhere there is internet access. This functionality includes the operation of the Qualys virtual and hardware appliances used for addressing private network addresses. The tool includes network discovery, asset mapping, prioritization, vulnerability assessment, centralized reporting and remediation tracking. Qualys employs a trouble-ticketing feature to help in tracking and remediating vulnerabilities and other problems across the network.

5#. OpenVAS

OpenVAS is a framework that includes services and tools for scanning and the complete managment of vulnerability.This is a tool that allows you to scan a target system (IP/HOSTNAME) based on a range of ports and a set of policies. The tool is supported by a database that is used from the vulnerability scanner to analyze possible problems whenever you find a listening service. The tool that scans receives daily updates from the database Network Vulnerability Tests “NVTs”.
