The Aikido alternative for understanding production exposure
Aikido integrates security into your code and pipelines to catch bugs during development. Intruder goes further down the lifecycle - continuously validating what is actually reachable in production to help you prioritize real-world exposure risk.
Secure what’s actually live, not just what’s in the pipeline
Aikido brings security into the development lifecycle to catch issues early across code and cloud configuration. Intruder takes a different approach by focusing on exposure in live environments, helping teams understand what is publicly reachable, which changes materially increase risk, and whether remediation actually reduces the external attack surface.
See beyond your inventory
Intruder uncovers internet-facing assets that sit outside standard workflows, including forgotten services, Shadow IT, and legacy infrastructure.
Deeper coverage, less noise
Multiple best-in-class scanning engines work together to deliver comprehensive, accurate results that traditional scanners often miss.
One place to manage external risk
Get a unified view of your security posture without switching dashboards. Manage your external perimeter, web apps, and cloud accounts from one live inventory.

Focus on issues that expand attack surface
Intruder prioritizes findings based on proven internet reachability and real-world exploit likelihood. This helps teams focus on issues that provide a direct path for attackers, such as misconfigured admin panels, rather than wasting time on theoretical bugs that can’t be reached.
Respond quickly to emerging threats
When critical vulnerabilities like Log4j or MOVEit emerge, hours matter. Intruder's Emerging Threat Scans automatically check your infrastructure when new CVEs are announced, so you understand exposure immediately and can act before exploits become widespread.
Fix the cloud leaks that attackers can actually see
Intruder identifies which cloud misconfigurations - like risky permissions or open storage buckets - are actually exposed to the internet. By pinpointing the settings that create a direct path for attackers, your team can prioritize fixes that reduce external risk instead of chasing hundreds of isolated posture issues.
Move from finding to fixing faster
Intruder fits into your existing developer workflow with native integrations for GitHub, GitLab, and Jira. GregAI triages findings and drafts plain-language remediation guidance so even non-security experts can fix issues fast.
Demonstrate risk reduction over time
Track cyber hygiene and generate instant, audit-ready reports for SOC 2 or ISO 27001. For ultimate efficiency, connect directly with your compliance platform to automatically sync vulnerability evidence to services like Drata and Vanta.

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.
