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.

How to configure Intruder to automatically scan for new services and threats

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.

What checks does Intruder perform?

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.

How do emerging threat scans work?

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.

What is the best Qualys alternative for lean security teams?

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.

What scanning engine does Intruder use?

Intruder is powered by industry-leading scanners, including Tenable, Nuclei, OpenVas, and ZAP. Learn more.

Does Intruder cover cloud and container security?

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.

Does Intruder include AI pentesting?

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.

How does Intruder's pricing compare to Qualys?

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.
