It is imperative for any national security agency to diagnose, identify, and address the possible vulnerabilities within their defense system to avert exploitation of the nation's security. Similarly, it is equally vital for any IT organization to have adequate checks in place to avoid compromising their most treasured ‘enterprise or customer data.’ Especially with the constantly evolving risks across cyberspace, backed by the increasing dependency on the cloud, vulnerability assessment has turned out to be a ‘must-have’ for businesses across industries.
Cybersecurity mishaps are on the rise, as the average cost of data breaches amounts to $3.86 million as per IBM data breach report. Surprisingly, only 38% of the leading global organizations are equipped with ways and means to combat such attacks. These numbers testify to the need to adopt vulnerability scanning mechanisms across diverse enterprise departments.
Organizations with sensitive data are the most susceptible to cyber threats and attacks. These potential threats must be kept at bay by security professionals before they face any attacks. A systematic approach toward discovering the security weaknesses, and evaluating the severity of vulnerabilities, followed by well-thought mitigation plans, drives all vulnerability testing tools’ success.
Different Types Of Vulnerability Testing Tools
The world is transitioning towards digital transformation, pushing forward the need to build a robust vulnerability management mechanism.
Vulnerability assessment tools are classified into four broad types:
1) Cloud-based vulnerability scanner Tool
Cloud-based vulnerability scanner primarily scans and detects possible risks to the websites and other online assets a company possesses. The demand for these scanners has sky-rocketed owing to the increasing dependency on the cloud, especially with the ‘new normal remote working style.
2) Host-based vulnerability assessment tool
Host-based vulnerability assessment scanners can be installed on any or every host within the system to provide insights on potential damages incurred by insiders or outsiders who enjoy partial access.
3) Network-based vulnerability testing Tool
Omnipresent connectivity within the network multiplies the risk of data compromise and this is why network-based vulnerability scanners came into existence. It identifies vulnerabilities in the network and possible network security attacks in wired and wireless systems in real-time.
4) Data-based vulnerability assessment tool
Databases are in today’s digital world overburdened with critical organizational data. Loss of such data not only results in monetary but also reputational damages. A data-based scanner searches for vulnerabilities within the database, such as weak passwords, missing patches, misconfiguration, etc., and highlights them to the users in real-time to avoid all underlying risks.

Risks are mounting with each passing day, along with the risk of revenue loss and brand name at stake multiplying. Customers rely on businesses with their personal data; hence, protecting them is mandatory. Vulnerability assessment tools form the spine of all firm's security mechanisms, assuring real-time discovery of threats and weaknesses. Other than protecting from external threats, vulnerability scanners also offer other benefits, including:
Affordability - Employing vulnerability scanning tools can be free or with minimum charges; in both cases, it is more affordable than employing full-time employees for the same.
Quick and reliable - The vulnerability assessment tools are quicker and more reliable as they take just a few hours to identify and combat all threats.
Performance - The scanners perform and are experts in treating almost all well-known risks, while humans might be restricted to excelling in only a few particular ones.
Automated - All functions available on penetration testing is entirely automated to perform regular scans without manual intervention or involvement.
No matter if someone chooses the best vulnerability scanner, its success will be entirely dependent on the business’s peculiar needs. It’s better to be careful about comprehending the business requirement fully before investing in one.
1. What is a Vulnerability assessment tool?
Vulnerability assessment tools allow a systematic review of security weaknesses in any information system. It conducts an overall evaluation of the system to check how susceptible they are to any known vulnerabilities, assigning severity levels to those vulnerabilities, and recommending remediation or mitigation if the need arises.
2. Why do we need a vulnerability testing tool?
Organizations with sensitive data are the most susceptible to cyber threats and attacks.
These potential threats must be kept at bay by security professionals before there are any attacks. Hence Vulnerability assessment is one of the key facets of the overall IT risk management strategy.
Vulnerability testing tools aid security researchers in detecting and fixing vulnerabilities, thus creating a safe cyber environment.
3. Which tool is recommended for open-source vulnerability scanners?
Open Source vulnerability scanner identifies and mitigates possible risks associated with the open-source software within the code and associated dependencies.
Grabber is a popular open-source web application scanner capable of detecting security vulnerabilities in web applications. It scans and recommends areas of vulnerability within Cross-site scripting, SQL injection, Ajax testing, File inclusion, JS source code analyzer, and Backup file check.
The ease of use and portability are the key reasons for its popularity, though it is not the fastest as other scanners.
4. How do vulnerability assessment (VA) Scanning tools work?
Post defining the target scope of vulnerability assessment, the type of scan is confirmed using several techniques and strategies, anticipating the devices’ responses. Basis the reactions received from devices, the scanner ensures the vulnerability severity and accordingly recommends a mitigation plan to patch such underlying gaps.
