The ImmuniWeb alternative for lean security teams
ImmuniWeb provides a high-end AI platform for web, mobile, and dark web security. Intruder offers an agile alternative for fast-moving teams - combining continuous attack surface discovery, cloud posture analysis, and web vulnerability scanning in one integrated platform.
One platform, not separate products
ImmuniWeb’s AI Platform covers a broad range of security use cases through distinct products like ImmuniWeb Discovery and Neuron. Each addresses a specific need, and their zero false-positives SLA is backed by human analyst verification,a process that reflects a focus on precision and compliance.
Intruder takes a different approach by combining continuous vulnerability scanning, attack surface management, and cloud security posture (CSPM) into a single, self-service platform. Instead of purchasing and coordinating separate products, your team gets one integrated workflow to discover assets, identify risk, and drive remediation, delivering results in hours, not days.
Continuous, automated protection
Intruder continuously monitors for new assets across your external and cloud environments, triggering scans automatically when something changes.
Built for teams that need to move fast
Get started in minutes, not days. Intruder is designed for lean teams to run independently, without needing dedicated security analysts or a managed service.
Eliminate blind spots across your attack surface
Uncover forgotten subdomains, Shadow IT, and orphaned services that sit outside your known inventory.
Trusted by thousands of companies worldwide
Unified visibility across 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 ensures you always know what is exposed and what has changed anywhere in your environment.
Stay ahead of risk as your environment changes
Your attack surface is not static, and neither is Intruder. Adaptive scanning automatically reassesses exposure whenever new assets appear or configurations change, combining proactive and reactive scanning to keep your environment secure as it evolves.
Focus on what attackers can actually exploit
Visibility is only useful if it leads to action. Intruder prioritises findings based on exploit likelihood and contextual risk, helping teams concentrate on issues attackers are most likely to leverage. Smart prioritisation cuts through noise so lean teams can act on what matters without needing to manually triage hundreds of findings.
Proactive protection against 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.
Move from findings to action without friction
Intruder bridges the gap between security and development with clear, actionable remediation advice and seamless integrations with Slack, Jira, and GitHub.
GregAI, Intruder’s AI security analyst, helps triage findings, explain root causes in plain language, and draft remediation notes, so teams can close issues faster without waiting for external analyst verification or managing a separate ticketing process.
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.
