Loved by 1000+ CTOs & CISOs worldwide
We are impressed by Astra's commitment to continuous rather than sporadic testing.
Astra not only uncovers vulnerabilities proactively but has helped us move from DevOps to DevSecOps
Their website was user-friendly & their continuous vulnerability scans were a pivotal factor in our choice to partner with them.
The combination of pentesting for SOC 2 & automated scanning that integrates into our CI pipelines is a game-changer.
I like the autonomy of running and re-running tests after fixes. Astra ensures we never deploy vulnerabilities to production.
We are impressed with Astra's dashboard and its amazing ‘automated and scheduled‘ scanning capabilities. Integrating these scans into our CI/CD pipeline was a breeze and saved us a lot of time.

Frequently Asked Questions
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.
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.
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.
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.
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.
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.
