The complexity-free Outpost24 alternative
Outpost24 is a powerful platform, but it can be difficult to operate for resource-strapped teams. Intruder delivers the same deep enterprise coverage without the complexity, bringing attack surface management, vulnerability management, and cloud security together in one platform.
Enterprise-grade security, zero complexity
If you're evaluating Outpost24, you need a comprehensive security assessment solution. Its extensive suite is powerful for large enterprises with dedicated teams, but for lean, fast-moving businesses that complexity is a barrier.
Intruder delivers powerful, enterprise-grade exposure management you need in an intuitive platform that takes you from setup to your first scan in minutes.
Setup in minutes
No long onboarding or heavy installs. Intruder is cloud-native, so you can go from signup to your first scan in minutes.
Unify your view of risk
Stop stitching together disjointed tools. Intruder brings attack surface monitoring, vulnerability scanning, and cloud posture checks into a single view, helping you prioritize what matters across your environment.
Automate your compliance evidence
Like Outpost24, Intruder finds your vulnerabilities, but it doesn't stop there. It automatically sends scan results to Drata and Vanta, generating audit-ready evidence for SOC 2 and ISO 27001.

Go from discovered to secured fast
While Outpost24’s ASM capabilities are robust, they often exist in a silo, separate from your vulnerability management. Intruder unifies discovery and testing. The platform detects new cloud assets and subdomains, then scans them automatically, reducing the delay between finding new exposure and understanding the risk.
Secure your cloud from the inside out
Your biggest cloud risks often aren't on the perimeter; they're in the configuration.
Intruder integrates directly with your AWS, Azure, and Google Cloud to find the root cause of potential breaches - such as overly permissive IAM roles or unencrypted storage buckets. Instead of just showing the open port, Intruder reveals the specific cloud rule that caused it.
Move fast when new CVEs drop
When a new high-impact vulnerability hits, waiting for the next scheduled scan leaves a gap. Intruder runs Emerging Threat Scans as soon as a check becomes available, helping you quickly assess exposure to vulnerabilities like React2Shell and prioritize fixes.
Detect what single-engine scanners miss
Why rely on a single opinion? Intruder uses multiple scanning engines and custom checks, then correlates results to improve coverage and confidence.
The Outpost24 competitor built for faster remediation
Intruder fits effortlessly into your existing stack with integrations for Jira, Azure DevOps, and ServiceNow. Real-time alerts in Slack and Teams keep developers in the loop, and our one-click re-scans allow them to verify their own fixes instantly, eliminating the friction between Security and DevOps.
