Frequently Asked Questions

What is a Website Scanner?
Plus

A website scanner is a security tool that checks your website's code and configuration for weaknesses that attackers could exploit to inject malicious code, steal data, or take control of your site.

What issues will be detected by the website scanner?
Plus

The Website Scanner can be used to scan a website for:

Blacklist Check - Checks 65+ search engines & security companies such as Google, Bing, Norton, Kaspersky, McAfee, Yandex, etc.

SEO Spam - Scans your top listed pages on Google to detect SEO Spam injection.

Health Check - A general security check which scans your website for header security, HTTPS encryption, cookie security, content security and more.

Malware - Scan your website for malicious scripts remotely.

Will it help me to detect malware on my website?

Am I secure if my website score is 100/100?
Plus

Scoring 100/100 in the website scanner does indicate that your site follows up-to-date security practices. However, it is not a certificate of absolute security. There are other key security areas in a website that is not scanned by the Website Scanner.

This website security check analyzes only those facets of your website that can be easily scanned externally. For complete security assurance, your server and application should be protected internally. But, the fact remains that scoring 100/100 means that you have better security than the majority of websites.

Why are Security Checks important for your Website?
Plus

The internet can be a very hostile place. No matter how perfectly you design your website, a dedicated hacker can turn it into a mess in seconds if you don’t pay attention to your website’s security.

Ignoring key security areas such as header security, HTTPS encryption, cookie security, content security, etc. can cause severe harm to your website and its reputation, if exploited.

Astra’s Website Scanner uncovers these frequently neglected but vulnerable security areas on your website. Additionally, it also lets you scan your website for malware, SEO Spam injection, and blacklisting.

What is the minimum & maximum score?
Plus

The minimum score is 0 and the maximum is 100. Whereas a site scoring 0 is categorized as the most vulnerable site, a site scoring 100 is recognized as one of the most secure websites on the basis of these tests.

How can I fix issues detected by the security scanner?
Plus

After a thorough pentest and/or vulnerability assessment, the security provider creates a detailed report that includes steps for remediation, steps to recreate the vulnerabilities that were found, and resources like expert support that might come handy in fixing these issues.
