Excellent technology and service **Rating:** 5.0/5.0 stars **Reviewed by:** Chris L. | Chief Technical Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 09, 2019 **What do you like best about Intruder?** Security is a minefield. Whilst many providers are doing their utmost best to increase the mysticism around this topic and extort high prices for little offerings, the team at Intruder have put together a system that is simple, transparent, robust, and easy to use. The tests are comprehensive and come with detailed remediation advice to help resolve issues. If you still have a query or a problem, there is a team available who can answer queries. **What do you dislike about Intruder?** Very little! If anything, the system is so simple to use that you could be forgiven for thinking you are missing something but, in reality, it stands up to scrutiny. We used intruder to tighten our security before two third party audits, and we passed on all fronts. **Recommendations to others considering Intruder:** Be sure to look at the available service tiers - it is worth paying for the level where you security issues are manually verified and false-positives removed. It will save you a lot of time. **What problems is Intruder solving and how is that benefiting you?** Working with large amounts of customer data, security is paramount. By using intruder as a third party assessor, we have an impartial view on where we need to improve. Critically, unlike other scanning solutions, intruder have come at me with a hard-sell for consultancy services to fix issues. This platform is the real deal, not a loss leader crammed with false-positives to convince you that you need to hire someone. ### 2. Excellent vulnerability scanning solution - easy to use and effective, a must have for tech startups **Rating:** 5.0/5.0 stars **Reviewed by:** Haydn B. | CEO and Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** April 07, 2019 **What do you like best about Intruder?** Intruder allows us to run regular vulnerability scans across our tech platform to reduce any vulnerabilities in our systems, which is critical for a tech startup. Best of all, we don't need any dedicated resources to manage it, it's simple to use and maintain and the team behind it are great. Highly recommended. **What do you dislike about Intruder?** There are a few nice to have features missing, but after speaking to the team these will be introduced as the product evolves over the next few months. **Recommendations to others considering Intruder:** Intruder is the easiest platform to use when running vulnerability scans across your infrastructure. It's cheap, efficient, and doesn't require a full time resource to manage it, it makes scanning your infrastructure easy. The team behind the tech are also great and ready to help if needed. They respond through their app very quickly and are really good at explaining the tool and guiding you through the features. I have recommended Intruder to a few friends who run tech startups and most of them have adopted the platform and love it too. **What problems is Intruder solving and how is that benefiting you?** As a B2B tech startup we need to make sure we're as secure as possible, a breach could be the end of our business. Intruder helps us to mitigate that risk. We also frequently get audited by our customers. Intruder allows us to sail through these audits with their regular scheduled scanning reports, which is great as it speeds up our procurement cycles with Clients. ### 3. Excellent security service **Rating:** 4.5/5.0 stars **Reviewed by:** Alastair J. | CTO, Mid-Market (51-1000 emp.) **Reviewed Date:** May 09, 2019 **What do you like best about Intruder?** The fact that intruder keeps scanning my infrastructure on an ongoing basis without any action from me. It has caught deployment misconfigurations on several occasions. **What do you dislike about Intruder?** There is not much to dislike. Earlier the biggest gap was that there was no AWS integration to automatically pull in targets, however, this has now been implemented! **What problems is Intruder solving and how is that benefiting you?** Security is of utmost importance to us. Intruder allows us to have confidence that our publically addressable infrastructure has no major and visible security issues. Intruder's regular reports also provide an audit trail for tracking state over time. ### 4. I love this tool!! **Rating:** 5.0/5.0 stars **Reviewed by:** Michael R. | Head of Sales, Financial Services, Small-Business (50 or fewer emp.) **Reviewed Date:** April 07, 2019 **What do you like best about Intruder?** Cyber security is so important - we provide a payments platform, we couldn't do it without knowing our customers were secure using it. Intruder is making sure we don't have any weaknesses where hackers could break in. Simplicity: We are using Intruder reports also for non-technical sales people, who otherwise are having a hard time demonstrate our state of security. **What do you dislike about Intruder?** Of course nothing can provide 100% protection, but for the cost, Intruder does a lot to help us. **Recommendations to others considering Intruder:** Stop considering and buy! You won't regret it!! :) **What problems is Intruder solving and how is that benefiting you?** We are always having to prove our security to customers - we are handling their payments data so it is the first thing they ask. It's nice to always have a recent report to show them proving our systems security. ### 5. Very helpful **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Wireless | Small-Business (50 or fewer emp.) **Reviewed Date:** November 11, 2019 **What do you like best about Intruder?** Great communication and very responsive. **What do you dislike about Intruder?** None, that I can find as of yet. Very impressive SaaS solution. **What problems is Intruder solving and how is that benefiting you?** Cyber Security. ### 6. Peace of mind when using internet-facing services **Rating:** 5.0/5.0 stars **Reviewed by:** John D. | Director, Small-Business (50 or fewer emp.) **Reviewed Date:** April 08, 2019 **What do you like best about Intruder?** Intruder is simple to set up and use. It allows me to implement, and change, blogs, active websites and web services without worrying that I've included a simple vulnerability and will be easily hacked. **What do you dislike about Intruder?** Nothing, really. Maybe some integration with some enterprise tools? **Recommendations to others considering Intruder:** Try it out! It's easy to configure and trial. The team is both deeply technical and good at communicating. Don't try and set up your own vulnerability scanning — it's easier and safer to leave it to professionals. **What problems is Intruder solving and how is that benefiting you?** I work in the cyber security industry, offering advice and comment, so having simple vulnerabilities in my web-facing services would be very damaging. I trust Intruder to cover me for this, with good remediation advice on anything I forget. ### 7. Vsibility **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Hospital & Health Care | Enterprise (> 1000 emp.) **Reviewed Date:** August 15, 2019 **What do you like best about Intruder?** We get visibility of risks and vulnerabilities, along with the steps we need to take address them. The dashboard lets me present risk and remediation progress to the IT groups and boards. **What do you dislike about Intruder?** The 30 day window between adding a removing device on the same license. I know why its there, but when we replace a DMZ service we have to wait before we can monitor it and ideally we need the monitoring from day one. **What problems is Intruder solving and how is that benefiting you?** It allows us to review and mitigate our DMZ service between pen tests. ### 8. Life saving, could not run my business without it **Rating:** 5.0/5.0 stars **Reviewed by:** Colleen W. | CEO , Small-Business (50 or fewer emp.) **Reviewed Date:** April 07, 2019 **What do you like best about Intruder?** We are a small team and we cannot spend time looking into security issues every day. Intruder's proactive scans mean that we get notified as soon as there is a problem, because Intruder is always watching over us. **What do you dislike about Intruder?** Would be nice to have the opportunity to schedule daily scans, but the proactive scans mean we are always covered against the latest threats. **Recommendations to others considering Intruder:** Couldn't recommend it more highly. **What problems is Intruder solving and how is that benefiting you?** As a provider of technology for children and seniors, the cyber security of our tech could not be more important. Intruder helps us keep our products fully up to date with the latest security patches, and helps us avoid serious data breaches. ### 9. An essential tool for any technology company - Intruder makes security easy **Rating:** 5.0/5.0 stars **Reviewed by:** Tony H. | COO & Co-Founder, Mid-Market (51-1000 emp.) **Reviewed Date:** April 05, 2019 **What do you like best about Intruder?** Intruder is so simple to use, but does such an important job, protecting our customer data against new vulnerabilities that get discovered on a daily basis. I like the reporting it does, and the feeling of "set it and forget it". **What do you dislike about Intruder?** It's a relatively new platform so it doesn't have as many features as some of the others we trialed, but it makes up for this with simplicity. **Recommendations to others considering Intruder:** You can get started easily - takes minutes to set up, really easy. **What problems is Intruder solving and how is that benefiting you?** We hold customer data and frequently have to prove our security for customers, our investors, and Board. ## Intruder Discussions -
