The Assetnote alternative for complete attack surface visibility
An attacker's view is essential, but it only shows you the perimeter. Intruder starts where Assetnote stops, unifying external asset discovery with internal cloud security, authenticated app scanning, and more.
Unified exposure management, not just discovery
If you're evaluating Assetnote, you're serious about continuous, real-time discovery. That's a critical first step, but discovery is just the beginning.
Intruder provides powerful Attack Surface Management (ASM) to find your external assets, then goes deeper with integrated vulnerability scanning, cloud security checks, and clear, actionable remediation advice to help you monitor and reduce risk across your entire environment.
See more than the perimeter
Get a complete view of your risk. Intruder runs 170,000+ checks across external, internal, and authenticated apps to uncover critical issues in your stack.
Secure your cloud from the inside out
Intruder's Cloud Security Posture Management (CSPM) integrates with AWS, Azure, and Google Cloud to pinpoint the real risks - like exposed security groups or weak IAM roles.
Respond to new headline threats in hours, not days
When threats like Log4j emerge, Intruder automatically re-scans your entire attack surface within hours.
Trusted by 3,000+ companies worldwide
All your risk in one place
Stop stitching tools together. Intruder brings attack surface discovery, vulnerability scanning, application testing, and cloud security checks into a single view. See not only that a port is open, but also the internal vulnerability on the server and the cloud misconfiguration that caused it.
Continuous asset discovery across your attack surface
Intruder continuously discovers assets across your external and cloud environments, finding everything from subdomains and APIs to cloud instances and login pages. By automatically detecting new or unknown assets the moment they appear, Intruder keeps your inventory complete, accurate, and ready for action.
Focus on what matters most
Once assets are discovered, Intruder highlights the exposures that matter most, such as misconfigurations, exposed databases, and admin panels. Using multiple scanning engines, Intruder detects up to 50% more issues than traditional scanners and helps teams focus on real risks, not noise.
Accelerate remediation workflows
Intruder bridges the gap between security and development with clear, actionable remediation advice and seamless integrations with Slack, Jira, and Azure DevOps.
GregAI, Intruder’s AI security analyst, helps triage findings, draft remediation notes, and explain root causes to accelerate fixes and close the loop between discovery and action.
Unified visibility for cloud and perimeter
From on-prem to multi-cloud, Intruder brings every asset, exposure, and misconfiguration into one live inventory. Continuous monitoring across AWS, Azure, and Google Cloud automatically detects new services and configuration changes, ensuring you always know what’s exposed across your environment.

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.
