The multi-cloud alternative to Amazon Inspector
AWS Inspector only covers your AWS accounts. Intruder provides a unified view across AWS, Azure, and Google Cloud, showing lean teams what’s actually exposed and what to fix first across their entire multi-cloud environment.
Beyond AWS-only visibility
Amazon Inspector is a native service designed to surface vulnerabilities and configuration issues across EC2, container images, and Lambda functions. For teams with simple, static environments, it provides helpful baseline visibility.
Intruder takes an attacker-centric approach by focusing on validating what is actually reachable from the public internet. Even for AWS-only teams, Intruder uncovers internet-facing assets that sit outside your expected scope and shows which changes materially increase real-world risk in production.
Find assets you did not know were exposed
Uncover forgotten subdomains, Shadow IT, and orphaned services that exist outside your standard AWS inventory.
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.
Deeper coverage, less noise
Multiple best-in-class scanning engines work together to deliver broad, accurate results that traditional scanners often miss.
Trusted by thousands of companies worldwide
Find internet-facing assets AWS can't see
AWS Inspector evaluates resources strictly within your configured AWS accounts. Intruder continuously discovers assets from an attacker's perspective - identifying domains, services, and APIs that are actually reachable from the outside. This helps you find legacy systems or "ghost" assets that may have bypassed your internal AWS management but remain open to exploitation.
Stay on top of changing cloud environments
Cloud environments move fast. Intruder automatically reassesses your exposure whenever configurations change - like an open port or new permission. This helps your team ignore the noise and focus on real, internet-facing risks.
Keep your apps and APIs secure
Amazon Inspector finds flaws in your code and cloud settings. Intruder completes the picture by testing your live websites and APIs from the outside. By testing your systems while they are running, Intruder identifies real-world risks - like broken logins or security flaws - that only appear when your system is actually live and exposed.
Multi-cloud coverage without tool sprawl
AWS Inspector provides deep visibility within AWS environments. If your infrastructure spans AWS, Azure, or Google Cloud, Intruder delivers consistent and unified security coverage across all three platforms. Teams get a single view of their cloud security posture in one place, regardless of where their systems are hosted.
Faster response to emerging threats
When critical vulnerabilities like MOVEit or Ivanti Connect Secure emerge, hours matter. Intruder’s Emerging Threat Scans quickly check your cloud, external attack surface, and applications so you understand exposure immediately and can act before exploits become widespread.
From finding to fixing, fast
Intruder connects to tools like Slack and Jira to keep remediation moving. GregAI, our AI security analyst, triages findings and explains root causes in plain language, so your team can close issues quickly without specialized security expertise.
Intruder checks your systems for 75+ web-layer security problems (such as SQL injection and cross-site scripting), 140,000+ infrastructure weaknesses (such as remote code execution flaws), and other security misconfigurations (such as weak encryption configurations, and systems which are unnecessarily exposed). Learn more about what checks we run.
Intruder’s emerging threat scans check your systems for newly discovered vulnerabilities automatically. This kind of proactive action is essential for businesses that don’t have processes in place to research the latest threats and manually run scans for them. Learn more.
Our team of experienced penetration testers will seek to identify serious weaknesses in your external targets that are undetectable by scanners. Continuous penetration testing is a bolt-on service available to Enterprise users and is sold and booked by the day. Learn more.
Intruder is powered by industry-leading scanners, including Tenable, Nuclei, OpenVas, and ZAP. Learn more.
