Also, the GUI is very pleasant and user friendly plus you don't have to be an expert on the subject matter to use this.

Quality Assurance Analyst

The only con I found in this software is lack of support. The response time of the customer service team is poor.

Dep. Head of Division Business Continuity Management, IT Oversight and Information Security Division

We use on premise solution. Great solution for small and big enterprises.

DIRECTOR

Great integrations with several technologies (such as Web Application Firewalls). Acunetix detects a lot of vulnerabilities and have the possibility to fix with easy ideas to do that.

Director and founder

Currently you have the "Allowed hosts" settings which is crappy in setting up. I need to set all (sub) domains to a different target.

The interface is built as "point a shoot", idiot proof. Currently, If I want to configure things I need to change xml config files on the server and reload acunetix.

IT Security Specialist

Also continous scanning option is an interesting thing for having continous security awareness of Your vulnerability level. Also login sequence recorder is an awesome tool.

Software Engineer

There is nothing so far to dislike this software.

This is one of the best value for money network scanner out there.

Nessus is still the industry leader in this arena, and the ability for the product to identify vulnerabilities accurately is still the high water mark to beat.

The software can be difficult to use sometimes and it doesn't always scan with the credentials needed to have compliant scans.

Network and System Administrator

There is also a very active community on their forums. Reporting is very informative, and scheduling makes it so you don't have to interact much after everything is all set.
