8 comprehensive safety tools and free web

Building off the latest version of Sandcat wanted to make a small collection of the most popular and powerful for the analysis of free web security.

On occasion I've read comparisons of these tools with others that only make their analysis based on signatures, such as Nikto or the free version of N-Stalker This comparison is wrong, since the approach is completely different. Both are focused on detecting vulnerabilities but the pattern-based applications generally have larger databases and updated comprehensive tools and therefore are complementary.

The characteristics are very similar in all of them make navigation and later released after the test. Except the last two scrawlr and Acunetix, which only detect SQL Injection and XSS respectively, all others look for common vulnerabilities.
