The world is moving towards digitalization; from small to large, every business has a website running to showcase its services, and simultaneously the need for the best website scanners is increasing.
In addition to providing services, they also keep user data in their databases, including cookies and personal information provided by users during registration.
Additionally, there are several technologies present outside that makes a website more efficient and easier to use for a user. Consequently, there are more opportunities to be vulnerable.
Basically, scanning is the second phase of ethical hacking, coming after reconnaissance. It aids in locating vulnerabilities present on the target.
Website scanners are often used to test dynamic web applications; as a result, they are also sometimes called dynamic application security tools (DAST).

What is a Website Scanner?
Website scanner tools enable analysts or testers to thoroughly scan a website and identify any vulnerabilities or weak points in the web application. Depending on the way the tool is made, the process can be either manual or automated.
The website scanner tools crawl through all of the web pages and files in a web app to look for flaws through an in-depth analysis, report them, and, if the scanner is able to do so, simultaneously fix them.
For cybersecurity researchers, the recon process has been greatly facilitated by the website scanner tools.
What Is the Work of the Website Scanners?
Since some vulnerabilities and loopholes are complex and some can be found by connecting multiple vulnerabilities, manual scanning is also a best practice to increase security to the next level.
The Website Scanner tool finds the vulnerabilities that are present on a website and specifies their severity level and CVE IDs if they are available, and it can also assign a CVSS score based on the findings.
This is because automated website scanner tools may not be able to find all types of vulnerabilities and loopholes.
Is it Illegal to Scan a Website for Vulnerabilities?
Yes, it is against the law to scan a website for vulnerabilities if you don’t have the owner’s consent to do so. It is necessary to obtain the website owner’s consent in order to conduct a scan of their infrastructure and then ethically report the results to them.
The owner’s permission is required because otherwise, you risk getting into legal trouble if the company decides to sue you for scanning and accuses you of stealing intellectual property (IP) rights.
How Do I Scan My Website for Malware?
The ability to scan for malware is frequently included in Website scanner tools, and it may be based on anomaly-based detection or signature-based detection. The tool will automatically report the results to the user.
Website scanner tools may be used to scan your website and find any malware that may be there. However, it depends on the scanner’s design whether it blocks the issue and resolves it or not.
In this write-up, we will read about the 10 best website scanners.
Best Website Scanners
Let us have a look at the ten best website scanners for 2023.
Acunetix is one of the best website Scanner widely used. It’s an automated website scanning tool that hunts for vulnerabilities like SQL injection, Cross-site Scripting, etc., and crawls through the website and detects the bugs, subsequently reporting them.
It catalogs all of the subdomains, categorizes the technologies being used, and, if any are discovered on the website, flags them as being outdated.
Based on its UI, the final scan report will be available in both PDF and HTML formats. However, a report could be created in any format using APIs.
A very interactive dashboard from Acunetix offers a statistical overview of all the web assets available, including the total number of targets and scans, the most vulnerable targets, and discovered vulnerabilities.
It has an interesting feature that shows a trend chart for each month for the previous 12 months about the number of bugs, targets, and the typical amount of time it takes to fix them. It is one of the best website scanner tools.

For effective policy enforcement and risk management, it can track multiple security testing programs. To reduce the risks in an easy and effective way, AppScan offers workable fixes.
Directly within the current deployment environment, it can conduct security analysis and make recommendations for corrective action.
To prevent expensive vulnerabilities that appear later in the development lifecycle, AppScan source mode can be added early on in the SDLC.
With the aid of AppScan, one can comply with industry benchmarks and standards like PCI DSS, HIPAA, OWASP Top 10, SANS 25, and others.

What is a website vulnerability?
Vulnerability is a type of weakness that opens a particular surface for attack. An attack may be caused by a website’s configuration errors, poor code validation, etc.
Some common website vulnerabilities are SQL Injection, Broken Authentication, Business logic flaws, cryptographic failures, command injection, etc. OWASP Top 10 mentions the top 10 common vulnerabilities found in a website during a period of time.
What are the basic security issues?
Unpatched bugs that have previously been discovered cause significant security issues. In many situations, using pirated software invites malware, which ultimately compromises the infrastructure.
