Website Security scanner are automated tools that scan various web applications, usually from the outside, in order to detect security vulnerabilities like Cross-Site Scripting, SQL injection, Direct injection, XSS and many more. The scanning process results into an Identification report which lists out the security vulnerabilities along with their risk score, a description of the issue, and a workable solution. Security vulnerabilities can be easily identified through these scanners as they give details about the security vulnerability, its impact and a possible solution for the same. Security scanners identify the security flaws in applications by scanning the source code. This helps to prevent the penetration of security flaws and hence is very important.
Many companies provide Web Application Security Scanner which can be used for web application penetration protection. They come in various forms and offer a wide range of functionalities, which include functionality to check for vulnerabilities in both Flash and JAVA. The scanners are available free of cost and they can be either freeware or shareware. The majority of these commercial scanners require the installation of the commercial edition of Internet Explorer, which is not generally required by the open source scanners.
On-Premises scanners are different in the sense that they run as server appliances. They require installation of the operating system and limited capacity. On the other hand, the commercial scanners for Internet Explorer do not require the installation of the OS since the browser itself is set up to use the OS. Hence the commercial version offers a higher level of protection than the open source counterparts. However, they lack the capabilities that the free and open source versions offer. They often fail to scan multiple websites simultaneously.
Both the scanners offer a free scan before you sign up and after you install the software on your computer. This way, you can test whether there are any vulnerabilities present in your system. On the other hand, the commercial version allows you to scan ten sites simultaneously. It also has advanced features such as URL Rewrite Check, Safe Mode, Smartscan, On-board scanning, and URL Redirection Check. These features make the commercial scanner superior to the free and open source scanner in terms of speed and security.
On the other hand, the commercial version of the web application has its advantages as well. It is compatible with the latest versions of the browsers like Firefox, Safari, and Chrome and is more secure than the alternative applications like FireFox and Safari. Also, it has an integrated database manager, which allows users to update the information without restarting the web application. The scanner also integrates with Microsoft Sharepoint Business Portal. Sharepoint is an ideal platform for creating online documents, calendars, pages, files, and presentations. Since the scanner is integrated with this platform, it helps in managing the corporate files and data with ease.
In contrast to the free and open source versions, the commercial version has several advanced security features as compared to the free versions. For example, it includes URL Rewrite Check, Safe Mode, URL Redirection Check, and Web application redirection Check. With these features, the commercial version can perform the task faster than the free version of the application. Apart from these features, the commercial version also has several customization options. This helps the company to manage their data in a better way.
The free and open source versions have limited security features. On the other hand, the commercial version of the application has additional features that help in performing the task faster. However, the on-premises version is more secure than the other applications available on the internet. In fact, you can download this application from the internet. However, you need to follow certain rules and guidelines when you download the application from the internet. The only thing that you should be careful about is the security of the website.
As far as the features and functionalities are concerned, both the commercial and the free versions of the commercial security saas are equally useful for organizations. However, the free version is more secure than the commercial version. This means that businesses can choose between the two versions according to their required level of security.
