The Qualys alternative for lean security teams
Qualys is built for large enterprise teams with the resources to run it. Intruder gives lean teams continuous coverage across their infrastructure, cloud, and apps, without the enterprise overhead.
Built for teams that need answers, not another tool to manage
Qualys is a deep, enterprise-grade platform built for large teams with time to operate it. Intruder takes a different approach: continuous exposure management that works right out of the box, helping your team move fast.

How Intruder compares to Qualys
Focus on what attackers are most likely to exploit
Severity scores alone don't tell you what's being exploited right now, so the wrong things get fixed first. Intruder ranks findings by exploit likelihood out of the box, so stretched teams always know what’s most important.

Know whether you're affected within hours, not days
When a critical CVE like MOVEit or Log4j breaks, the usual response is a manual scramble. Intruder scans your estate automatically as soon as a check is available and notifies you with the results, so you know if you’re exposed and can act quickly to remediate.
The depth of a web app pentest, whenever you need it
Manual web app pentests are costly and happen once or twice a year, leaving long gaps in between. Intruder's AI agents pentest your web applications on demand, at a fraction of the time and cost of a manual engagement, so testing keeps pace with every release.
Get fixes moving, not stuck in translation
Intruder writes findings in plain English with clear remediation steps, and GregAI answers follow-up questions and drafts the fix notes. With 15+ workflow integrations including Jira, Slack, and GitHub, issues land in the tools your developers already use, ready to pick up, not decode.
Intruder checks your systems for 170,000+ infrastructure weaknesses (such as remote code execution flaws), 75+ web-layer security issues (such as SQL injection and cross-site scripting), and other misconfigurations (such as weak encryption and services that are unnecessarily exposed). Learn more about what checks we run.
Intruder's emerging threat scans check your systems for newly discovered vulnerabilities automatically, as soon as a check is available. You'll know whether you're exposed without lifting a finger, with no need to research the latest threats or run scans manually. Learn more.
Intruder is a strong Qualys alternative for lean teams that want comprehensive exposure management without enterprise complexity. It combines attack surface management, vulnerability management, cloud security, and AI pentesting in one platform you can run with a small team and set up in minutes.
Intruder is powered by industry-leading scanners, including Tenable, Nuclei, OpenVas, and ZAP. Learn more.
Yes. Intruder runs daily cloud configuration checks across AWS, Azure, and Google Cloud to flag misconfigurations, insecure permissions, and exposed secrets. It also discovers and scans container images in your cloud registries, enabling you to catch vulnerable containers before they’re deployed in production.
Yes. Intruder's AI agents investigate and validate scan findings, confirming which are real risks in minutes. For deeper coverage, you can run a full AI pentest of your web applications on demand, at a fraction of the time and cost of a manual engagement. Full pentests are available at an additional cost.
Intruder offers transparent, flexible pricing with monthly or annual plans plus a custom Enterprise option, and you pay for what you scan. Qualys is typically priced per asset on annual enterprise contracts, which can be harder for smaller and mid-sized teams to predict and manage.
