What do you like best about Intruder?

The software is easy to use and setup is not to difficult. Because we had an external PEN test done, i could compare the result and it was more extensive then the result we had. Nothing was missed! So easy to use and reliable. Review collected by and hosted on G2.com.

What do you dislike about Intruder?

There are not many things I dislike after my tree trial use. So I will start a subscription for our servers and software and will have to come back to this. Preferably not! Review collected by and hosted on G2.com.

What problems is Intruder solving and how is that benefiting you?

Our customers expect we do everything to guarantee the security of their data, which we handle in providing the services they want. As a small company, this needs a high level of automation and recurrent feedback. Intruder offers this in a way more manageable way than outsourcing this to third parties. I don't think the subscription model is cheap, but it is a good deal compared to outsourcing. Review collected by and hosted on G2.com.

What do you like best about Intruder?

Intruder frees up time to focus on our core business, which is important in a small team. Its easy to set up, well supported and for us its good value. I particularly like the ability to automatically put tickets into Jira and the detailed redediation advice they come with. Its great to be able to run scans and get an up to date report any time its needed. I also like the automatic tracking of the speed at which we resolve issues. I'm sure using Intruder helped with the great results we got in a recent Pen Test. Review collected by and hosted on G2.com.

What do you dislike about Intruder?

I have no significant issues with Intruder. The hardest thing for me working out what to set up the scans against, which the support team hand held me through wth great professionalism. Review collected by and hosted on G2.com.

What problems is Intruder solving and how is that benefiting you?

Intruder provides us with a quick and easy way to address our vulnerability scanning needs. It addresses the problem that I am sure many small businesees must share? Vulnerability scanning is a very important area but also one that requires a level of expertise that few small businesses will be able to maintain in house. Intruder has bridged that gap very effectively for us. Review collected by and hosted on G2.com.

What do you like best about Intruder?

The scanner allowed our company to pass security assessments and allowed us to participate in various engagements. It helped me determine what computers were out of date with software, and some registry issues I didn't know existed in Windows. The monthly reports were a great tool to see what updates were available, especially as a small business running remotely. The GUI is great to see what's wrong at a glance. Customer support is quick and friendly. Review collected by and hosted on G2.com.

What do you dislike about Intruder?

Best to be installed in person in case troubleshooting needs to happen. I know the team is working on making installations easier. Review collected by and hosted on G2.com.

Takes some of the donkey work out of managing assets. Lets us focus on running the business, with some degree of security that we've covered some of the essential security vulnerabilities in various deployed assets. Review collected by and hosted on G2.com.

What do you dislike about Intruder?

Remediation scans used to take ages, they're a lot quicker now though. The 'session expired' messages when logging in again (after a few days absence) are annoying, but not deal breaker. Review collected by and hosted on G2.com.

What do you like best about Intruder?

Easy to use and configure. The UI is great, and the Dashboard gives you all the information that you need in one place. You can dig deep into the scans and are provided with not only the details but links to the CVE. You can schedule scans as you wish, and the service also automatically scans new zero-day vulnerabilities. It automatically generates reports that are emailed to you. These reports can be used as prove that you are actively monitoring for external threats and misconfigurations that can leave you vulnerable. Works on Cloud, Hybrid and Stand-a-Lone Hardware Networks.

We use this every day! Review collected by and hosted on G2.com.
