Outstanding Experience with No Drawbacks **Rating:** 5.0/5.0 stars **Reviewed by:** Nic H. | Operations Director, Small-Business (50 or fewer emp.) **Reviewed Date:** December 16, 2025 **What do you like best about Intruder?** What we’ve found most helpful about Intruder is the clarity and prioritisation of its findings. Rather than overwhelming us with low-value noise, it highlights vulnerabilities that genuinely matter and explains why they are important. The continuous scanning model is a big advantage, as it means new issues are identified as our environment changes, rather than relying on occasional point-in-time tests. The level of context provided for each finding, including exploitability and practical remediation guidance, makes it much easier to take meaningful action. Intruder also gives excellent visibility of externally exposed assets, which are often the areas of highest risk. The dashboard is clean and intuitive, allowing us to communicate risk clearly to both technical and non-technical stakeholders, and it integrates smoothly into our existing workflows without heavy setup. Overall, it provides ongoing assurance that we are actively reducing real-world risk rather than simply running scans for compliance. **What do you dislike about Intruder?** At this stage, we haven’t identified any significant downsides. The platform has been straightforward to set up, the findings have been clear and actionable, and it has integrated well into our existing processes. If anything, any future feedback is more likely to be around additional features or refinements rather than core shortcomings, but so far our experience has been entirely positive. **What problems is Intruder solving and how is that benefiting you?** Intruder is solving the problem of infrequent, point-in-time vulnerability testing. Previously, vulnerability scanning was largely an annual exercise carried out by third-party suppliers, which meant issues could exist for months before being identified. By using Intruder to run regular weekly scans, we now have continuous visibility of our security posture and can identify and address vulnerabilities much earlier. This significantly reduces risk, shortens remediation timelines, and gives us far greater confidence that new or emerging issues are not being missed between formal assessments. ### 2. Intruder: Effortless and Effective Security Scanning **Rating:** 5.0/5.0 stars **Reviewed by:** Scott D. **Reviewed Date:** November 05, 2025 **What do you like best about Intruder?** I appreciate Intruder's easy user interface, which allows me to navigate effortlessly. The automatic scanning feature is invaluable as it runs scans whenever a new issue arises, saving me the need to initiate them manually. This automation helps in quickly identifying new vulnerabilities and understanding what they pertain to. I love the capability to easily track issues within the interface until they are resolved, simplifying my workflow significantly. Additionally, Intruder's proactive approach in staying on top of identifying potential security vulnerabilities means I don’t have to allocate someone specifically for constant monitoring, which is a considerable advantage. The initial setup was straightforward as well, only requiring the creation of dedicated user accounts for the application and the Intruder bot to log in and perform deep scanning. Overall, Intruder not only maintains a seamless usability but also effectively integrates with our development tools like Azure DevOps, making it an incredibly valuable resource in our security management efforts. **What do you dislike about Intruder?** Nothing comes to mind. **What problems is Intruder solving and how is that benefiting you?** I use Intruder to identify security vulnerabilities in our applications and networks, providing solutions to fix these issues. Its automatic scanning and easy interface save time by eliminating the need for constant monitoring. ### 3. Effortless Setup, Enhances Network Security **Rating:** 5.0/5.0 stars **Reviewed by:** Jacob H. **Reviewed Date:** December 18, 2025 **What do you like best about Intruder?** I really appreciate that Intruder helped us gain visibility on our network, which made it easier to understand our risks and take concise action to tighten our defenses. It's incredibly simple to set up and see exactly what's going on, unlike other programs that are complicated. I also love how quickly we had it running, just within a few hours. Right now, we're in the honeymoon phase and enjoying all of it. **What do you dislike about Intruder?** I would likely say more information on licensing costs - it was challenging to find this on the site. But this in no way impacted the quality or usability of Intruder. **What problems is Intruder solving and how is that benefiting you?** Intruder helps us gain visibility on our network, close security gaps, and easily understand risks to enhance our defenses. ### 4.

Security Operations Manager **Rating:** 5.0/5.0 stars **Reviewed by:** Khodor B. | Security Operations Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** June 03, 2025 **What do you like best about Intruder?** I’ve been testing out Intruder.io for the past couple of weeks, mainly to get a feel for how well it fits into a cloud-heavy environment. So far, I’ve integrated it with Azure and ran tests using their agent, and I have to say—I'm mostly impressed. First impressions: The UI is clean and intuitive. I didn’t need to dig through documentation to figure out where things were. Connecting it to our Azure environment was smooth—probably one of the easiest integrations I’ve done in a while. Once the scans kicked off, results started coming in quickly, and the platform did a solid job of flagging vulnerabilities with enough context to take action. Agent test: I also tested the internal scanning using their agent. Setup was simple, and the scan ran without a hitch. It’s lightweight and didn’t bog down the VM, which is something I always look out for. Final thoughts: For someone looking to get up and running fast with a reliable vulnerability management tool—especially in the cloud—I think Intruder.io delivers. It's not the deepest tool for hardcore pentesters, but for ongoing visibility and clean reporting, it’s exactly the kind of lightweight, effective solution I’d recommend for SMBs or hybrid cloud setups. **What do you dislike about Intruder?** Advanced users might miss some of the granular control you’d get in something like Nessus or OpenVAS. **What problems is Intruder solving and how is that benefiting you?** With so many moving parts—VMs, endpoints, services—it’s easy for issues to go unnoticed. Intruder helps by automating the scanning process and clearly prioritizing real risks instead of flooding me with low-impact noise. Since integrating it with Azure and testing the agent, I’ve had better visibility into both external and internal threats, without needing to manually trigger scans or sift through overwhelming reports. It’s saving me time, reducing risk exposure, and making it easier to stay proactive about security. ### 7. Small teams greatest helper **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** August 11, 2025 **What do you like best about Intruder?** Intruder stands out for its ease of use, its clean, intuitive interface means I can start a scan or review results without wasting time navigating complex menus. Getting set up was quick and straightforward, with minimal configuration required to get it running effectively. Despite its simplicity, it offers a rich set of features, from comprehensive vulnerability scanning to easy rescan options, which makes it a perfect fit for frequent use. The platform integrates smoothly with our workflow, so running scans, reviewing results, and taking action feels seamless rather than disruptive to daily operations. Additionally, the Customer Support has been some of the best, they respond within the hour of your request and can schedule meetings for discussion the next day if needed. Also the CSMs automatically schedule meetings to check up and update you about new tools they released. **What do you dislike about Intruder?** The only drawback I’ve noticed is that scan times can occasionally be longer than expected, especially during peak usage periods. It’s not a dealbreaker, but quicker turnaround would make the process even smoother when dealing with time-sensitive issues. **What problems is Intruder solving and how is that benefiting you?** Our biggest challenge as a small security team is keeping up with the constant stream of potential threats and vulnerabilities across our environment. Intruder helps us overcome this by automating the discovery, prioritization, and tracking of security issues, allowing us to stay on top of our IT security without becoming overwhelmed. It pinpoints vulnerabilities that would have taken us days to identify manually, and provides clear, actionable remediation steps that save us valuable time. The ability to quickly rescan after fixes means we can validate our work immediately, ensuring risks are addressed before they can be exploited. This efficiency not only improves our security posture but also frees up our team to focus on other critical initiatives. ### 8. Effortless Setup, Reliable Scans With Room for Improvement **Rating:** 4.0/5.0 stars **Reviewed by:** Iason G. **Reviewed Date:** December 22, 2025 **What do you like best about Intruder?** I like how easy Intruder is to set up and execute. The autoscanner is one of the most important features for me, along with the continuous updates on critical security vulnerabilities. **What do you dislike about Intruder?** Some SQL injections are not found. We had one recently that a colleague found, but Intruder apparently skipped or didn't manage to find. It doesn't integrate with our end-to-end tests, which would be very helpful. **What problems is Intruder solving and how is that benefiting you?** Intruder scans our application and endpoints monthly to promptly identify security vulnerabilities. ### 9. Easy to set up, easy to integrate, great customer service. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** September 05, 2025 **What do you like best about Intruder?** The interface is super simple. From experience with vulnerability scanners the config can sometimes be made to feel more complex than it needs to be. However Intruder is painless. I've also raised a few questions with the customer support team and the comms are always, fast, to the point. Other SaaS security providers could take note. It's also significantly cheaper than alternatives. **What do you dislike about Intruder?** If you are dealing with an incredibly large number of different resource types the interface and filters may be somewhat restrictive but for most SME and enterprise it's perfect. **What problems is Intruder solving and how is that benefiting you?** Its a low cost, easy to use full scope scanner. It solves a lot of problems. There really isn't any reason to get this stuff wrong as it's made super easy and with in reach for any business. ### 10. Intruder for Vulnerability Scanning **Rating:** 4.5/5.0 stars **Reviewed by:** Richard G. | CISO, Mid-Market (51-1000 emp.) **Reviewed Date:** August 08, 2025 **What do you like best about Intruder?** Super easy to configure to include all cloud resources in both AWS and Azure to ensure vulnerability issues are identified and considered in a timely manner. Added benefit of application scanning through addition of credentials for application login to perform a level of penetration testing too. **What do you dislike about Intruder?** Can have a number of false positives - but these can be easily tagged as noise. **What problems is Intruder solving and how is that benefiting you?** Keeping on top of vulnerabilities across our cloud infrastructure and applications. Ease of using a single pane of glass across both AWS and Azure (that we use) as well running application security. ### 11. A Robust and User-Friendly Vulnerability Management Solution **Rating:** 4.0/5.0 stars **Reviewed by:** Murali T. | Head Of Cloud, Small-Business (50 or fewer emp.) **Reviewed Date:** April 02, 2025 **What do you like best about Intruder?** I appreciate Intruder.io's user-friendly interface, which simplifies navigation and operation, making it accessible even for those with limited technical expertise. Additionally, its extensive vulnerability scanning capabilities provide comprehensive coverage, ensuring that potential security issues are thoroughly identified and addressed **What do you dislike about Intruder?** While Intruder.io offers a user-friendly interface and extensive coverage, generating reports for specific resources isn't intuitive. Additionally, updating targets requires deletion and re-adding, likely due to licensing constraints, necessitating reliance on external DNS configuration **What problems is Intruder solving and how is that benefiting you?** We utilize Intruder.io to conduct weekly scans of our systems, effectively identifying vulnerabilities and gaps in our security posture. This proactive approach enables us to address issues promptly, thereby reducing our exposure to potential threats. Additionally, Intruder.io's Emerging Threat Scans automatically assess our environment against newly identified critical vulnerabilities, ensuring we stay protected against the latest threats. citeturn0search0 ### 12. Effortless Security Scanning with Great Value **Rating:** 5.0/5.0 stars **Reviewed by:** Riccardo F. | Cloud Architect / Systems administrator, Small-Business (50 or fewer emp.) **Reviewed Date:** April 30, 2025 **What do you like best about Intruder?** Intruder is an incredibly easy-to-use security scanning service that automatically and efficiently identifies vulnerabilities. It's a powerful tool that eliminates the stress of managing cybersecurity risks, making it ideal for both small teams and larger organizations. The intuitive interface, clear reports, and time-saving features make it a standout solution. On top of that, the pricing is very reasonable for the value it provides. Highly recommended for anyone seeking a hassle-free security solution. Implementation is straightforward, even if your environment includes firewalls or authentication systems. You can simply add exclusions, which are conveniently provided during the configuration process. We run scans on a weekly basis, benefiting from the automated scanning features (every month), while also conducting manual scans whenever we release something new to ensure security remains airtight. The customer support is outstanding — responsive, efficient, and highly helpful. Additionally, integrating Intruder with our platform was very easy. **What do you dislike about Intruder?** We've been using Intruder for years, and right now there's nothing we dislike about it. **What problems is Intruder solving and how is that benefiting you?** It alerts us in case of vulnerabilities (such as software, both at the application level and OS). It also precisely identifies which vulnerability was found and where it was detected. ### 13. Great vulnerability scanner and great team **Rating:** 5.0/5.0 stars **Reviewed by:** Christophe L. | CIO, Small-Business (50 or fewer emp.) **Reviewed Date:** June 30, 2025 **What do you like best about Intruder?** The interface is simple but it gives me exactly what I need. The daily scans are constantly pointing out improvements to increase the security of our platform. The few times I needed explanations, the support team was exceptional. Intruder not only flags vulnerabilities, but also provides recommendations on how to eliminate them. **What do you dislike about Intruder?** So far, I cannot think of any negatives. **What problems is Intruder solving and how is that benefiting you?** We embraced Intruder a few weeks ago. It is the tool that we needed to enhance the security of our environment. ### 14. Cloudn8v & Intruder.io **Rating:** 5.0/5.0 stars **Reviewed by:** Jonathan H. | Director, Small-Business (50 or fewer emp.) **Reviewed Date:** March 21, 2023 **What do you like best about Intruder?** We were after an authenticated, comprehensive webapp and cloud asset vulnerability scanner, and after testing the intruder.io platform, we found numerous positive features that make it a standout option in the marketplace. **What do you dislike about Intruder?** One potential negative of Intruder.io is the 30-day lock on moving authentication domain targets. If a user wants to switch to a new domain or target for authentication testing, they must wait for 30 days before they can do so. This limitation can be frustrating, especially if switching domains is a requirement. **What problems is Intruder solving and how is that benefiting you?** Assisted in pen-testing & positive vulnerabilities in deployed infrastructure. ### 15. Easy to implement for my first time navigating new PCI requirements **Rating:** 4.5/5.0 stars **Reviewed by:** Chris T. | Technical Director, Small-Business (50 or fewer emp.) **Reviewed Date:** February 27, 2025 **What do you like best about Intruder?** We have a large task ahead, with changes in PCI 4.0 requiring that even sites which do not process card details directly require a level of compliance. We needed a partner who could perform compliant scans and would give our developers clear guidance on how to mitigate any issues it found. We tried out a couple of services, but Intruder came out tops, with a simple interface, easy to understand reports, plus the benefit of constant emergent threat scanning. This gives us the confidence that our web applications will remain as secure as possible in the long term. The pricing is competitive and easy to understand, plus the discounts start to kick in when scanning more than one application which will greatly reduce our costs as we manage about 35 websites which now have this requirement. I had a few questions along the way which were promptly responded to with really good advice. **What do you dislike about Intruder?** It scans for literally everything and the scans take a very long time to complete. It would be great to be able to filter the scans to look for specific issues, rather than completing a whole scan each time. **What problems is Intruder solving and how is that benefiting you?** Making PCI 4.0 compliance an easier process for our developers ### 16. Great external infrastructure assessment Tool **Rating:** 5.0/5.0 stars **Reviewed by:** James R. | Senior ICT Security Specialist, Enterprise (> 1000 emp.) **Reviewed Date:** June 09, 2025 **What do you like best about Intruder?** the emerging threats scan is great as it highlights potential emerging vulnerabilities **What do you dislike about Intruder?** the large amount of IP addresses scans could potentially come from. Dont really want to open firewalls to large subnets **What problems is Intruder solving and how is that benefiting you?** Having a constant view of our external attack surface ### 17. Intruder is a must-have tool for cybersecurity. **Rating:** 5.0/5.0 stars **Reviewed by:** Vahagn S. | Founder and CEO, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2025 **What do you like best about Intruder?** Intruder makes vulnerability management easy and fast. Its intuitive interface, seamless integration, and proactive threat detection simplify our cybersecurity operations significantly. **What do you dislike about Intruder?** Occasionally, the detailed reports can be overwhelming for beginners, but overall, there's very little to dislike. **What problems is Intruder solving and how is that benefiting you?** Intruder efficiently identifies and prioritizes cybersecurity vulnerabilities across our websites and APIs, enabling quick remediation and significantly enhancing our overall security posture. It saves considerable time, prevents potential breaches, and ensures continuous compliance. ### 18. Functionality and Support **Rating:** 5.0/5.0 stars **Reviewed by:** Amila P. | CTO, Small-Business (50 or fewer emp.) **Reviewed Date:** March 26, 2025 **What do you like best about Intruder?** I like the functionality they have provided for a quick vulnerability scan on infrastructure or applications. Additionally the support provided by Joe was quick and precises. **What do you dislike about Intruder?** Probably the licensing approach to targets **What problems is Intruder solving and how is that benefiting you?** Getting Vulnerability scans done in an adhoc manner ### 19. Covers the essential security bases for your managed assets **Rating:** 4.5/5.0 stars **Reviewed by:** Dave B. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 21, 2024 **What do you like best about Intruder?** 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. **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. **What problems is Intruder solving and how is that benefiting you?** Reminders for regular updates (as needed) and catching various framework updates etc... ### 20. Easy to use vulnerability scanner **Rating:** 5.0/5.0 stars **Reviewed by:** Dimitar K. | InfoSec, Mid-Market (51-1000 emp.) **Reviewed Date:** November 22, 2022 **What do you like best about Intruder?** Intruder.io is an exceptional online vulnerability scanner that has completely transformed our cybersecurity approach. Its user-friendly interface and powerful scanning capabilities allow us to proactively identify and address potential weaknesses in our digital infrastructure. **What do you dislike about Intruder?** So far, so good! It's hard to say what you dislike when you like everything in a product! **What problems is Intruder solving and how is that benefiting you?** Intruder is helping us with automated testing/scanning our web app for vulnerabilities and exploits we may miss. Also helps with meeting our compliance requirements! ### 21. Intruder.io Makes Security Monitoring Effortless and Effective **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** August 25, 2023 **What do you like best about Intruder?** My experience so far has been excellent, the web interface is "buttery smooth", easy to get started with, easy to use and affordable. Their support staff has been responsive and helpful. Adding targets, integrating with our cloud environment and integrating with JIRA were very simple. Once all our targets were setup, we built a weekly scan schedule which is fantastic. However, one of my favorite features is integration with Microsoft Teams and automatic scans for emerging threats. For example, if I have started my weekend already, sometimes Intruder.io becomes aware of an emerging threat. It will immediately kickoff a new scan of our infrastructure to detect if we are vulnerable to this new threat. It will notify us via teams it is starting the scan, and notify when complete and what the findings were. So I can be at a kids sporting event on a saturday and get all these updates. It feels like we have a virtual employee working for us, watching our back for new threats, scanning for them, and then reassuring us we are okay. I was able to purchase without contacting a sales rep. I was able to use the pricing sliders on their website to build the plan that is right for our business. **What do you dislike about Intruder?** This may be a credit to Intruder versus a dislike. I'll explain. We have detected 2 "anomolies or vulnerabilities" that may have been false positives. However, I will say, there is strong evidence to suggest that these were not false positives, but that Intruder actually detected a real world anomoly. For example, it picked up UPNP exposure on an Azure resource that is not a VM we control or have visibility to. We ran our own scan and detected the same UPNP exposure, validating Intruders findings. The finding went away the next day on a followup scan using Intruder. After working with the Intruder team, we beleive this actually revealed the "man behind the curtain", meaning Microsoft Azure infrastructure that is never meant to be seen. While we will never know what this was, it may be a credit to Intruder for finding it and raising our attention to it. **What problems is Intruder solving and how is that benefiting you?** Persistent scanning of our public facing infrastructure, and producing reports we can use for audit and compliance. ### 22. Anyone who cares about security should be running intruder.io **Rating:** 5.0/5.0 stars **Reviewed by:** Mark T. | Small-Business (50 or fewer emp.) **Reviewed Date:** March 24, 2023 **What do you like best about Intruder?** We used to run automated vulnerability scanners, but since support for that ended, we've been unable to find one as easy to use until we found intruder.io. So simple to set up and start scanning your infrastructure with a 14 day free trial. Quickly identifies systems with known vulnerabilities within your production and office environments. Unlike previous systems I've used, we've been able to run internal scans of our product to be even more comprehensive. Be sure to check pricing closer; not as expensive as it would initially appear. **What do you dislike about Intruder?** Don't use authentication license on production systems, intruder.io scans will change data within your system as part of the tests that are being run. This should be more obvious, lucky we tested on staging systems first. **What problems is Intruder solving and how is that benefiting you?** Making us aware of security threats before would-be attackers can take advantage and we can take action to resolve these. Continuously scans for emerging threats, we can manually keep up otherwise. ### 23. Intruder helps to build more Proactive, Secure, and Agile IT Teams **Rating:** 5.0/5.0 stars **Reviewed by:** Ben C. | Mid-Market (51-1000 emp.) **Reviewed Date:** March 08, 2023 **What do you like best about Intruder?** This platform enables my team not to waste time testing against known vulnerabilities and focus on hardening our services and solutions. Intruder also provides a huge benefit in proactive Change detection, where it will advise when new instances or hosts are detected as well as any vulnerabilities that it may have, allowing for more agile change management. This also allows the teams to learn positively and move faster. **What do you dislike about Intruder?** Once a threat is detected, it would be nice if there was a button on the detected threat to allow customers to retest and validate that their fix has resolved the vulnerability without having to run an unscheduled full gamut pen test to clear the issue out. This slows the remediation process. Having a button that can check and clear that one vulnerability would mean quicker cycle time and I am sure less expense for Intruder from a Cloud Compute standpoint. **What problems is Intruder solving and how is that benefiting you?** Intruder helps us solve: - Proactive Change Detection - Attack Surface Management - Post Development and Patch Validation - Hardened Cyber Security Posture We have greater confidence from our Board that our team has an excellent grasp on the threats in the wild and that we are ensuring our services are safe. ### 24. Convenient but thorough penetration and vulnerability testing wrapped in an affordable package! **Rating:** 5.0/5.0 stars **Reviewed by:** Roy M. | Director of Information Technology, Mid-Market (51-1000 emp.) **Reviewed Date:** October 14, 2022 **What do you like best about Intruder?** We were in need of a testing product that would test from the inside out and outside in. That's what first attracted us to Intruder. The product is well laid out with a clear, concise Cloud interface. Small footprint on internal devices reduces performance degradation. Thorough testing of all targets with well-documented results. Remediation instructions are excellent and easy to follow. Emerging threat scans may prove critical. **What do you dislike about Intruder?** Distribution of the internal agent is still somewhat of a manual process. However, instructions were provided for distribution through Microsoft Intune and we have other packages capable of selective installations. Scripting makes the installation easier for a large installed base. **What problems is Intruder solving and how is that benefiting you?** We were lacking on-demand/scheduled penetration testing of our public IPs and servers - Intruder fit the bill. While we have excellent patching capabilities and vulnerability reporting through our RMM and Endpoint Security products, we needed a product which would manage the process of performing complete vulnerability scans and more importantly, provide us with detailed remediation instructions. This is an area where Intruder shines. While we're just starting out with the product, we are anticipating a huge time savings compared with our prior methods of vulnerability elimination. ### 25. Intruder is a great product giving peace of mind **Rating:** 5.0/5.0 stars **Reviewed by:** Bruce A. | Owner, Small-Business (50 or fewer emp.) **Reviewed Date:** December 19, 2022 **What do you like best about Intruder?** Intruder keeps ahead of the threats that emerge every day. As threats emerge or sites are tested against them and we are notified of the results. TAkes away the constant worry of threats on my business. **What do you dislike about Intruder?** Nothing, it is a great service with good reporting and notifications. **What problems is Intruder solving and how is that benefiting you?** The background monitoring of new threats, as well as the monthly complete threat testing saves my team the distraction and allows them to focus on productive work. ### 26. Simple, straight forward & easy to use **Rating:** 5.0/5.0 stars **Reviewed by:** Matt K. | Mid-Market (51-1000 emp.) **Reviewed Date:** March 09, 2023 **What do you like best about Intruder?** The Cloudbot feature handled our target management automatically, reducing overhead significantly. The Noise Reduction feature drew attention to actual issues so our DevSecOps teams could spend their limited resources fixing them.
