Pricing
Detectify targets mid-market and larger organizations with its research-driven EASM and DAST. It sells these as separate, modular subscriptions — Surface Monitoring for external attack surface discovery and Application Scanning for DAST — priced per subdomain or per domain, with Enterprise quotes for larger scopes. There is no public free tier, though a trial is available. Running both modules for full coverage adds up, which makes it a meaningful investment for many teams.
Tenable's attack surface management typically sits inside its broader exposure management platform. Pricing is quote-based, driven by asset counts, cloud connectors, and the modules you activate. Enterprises usually negotiate custom contracts for Tenable's wider suite (Vulnerability Management, Web App Scanning, ASM), so the initial investment can be substantial. See vendor for a quote.
Intruder offers transparent, tiered pricing published on its site, making it accessible for small-to-medium businesses (SMBs) and mid-market companies. Plans scale by the number of targets (IPs, domains, apps) and tier, with a 14-day trial. Teams generally find it a straightforward option for continuous external scanning without enterprise-level overhead. See vendor for current tier pricing.
CrowdStrike Falcon Surface is part of the larger CrowdStrike Falcon platform. Its pricing usually bundles with other Falcon modules such as EDR or XDR, and standalone EASM is quote-based. Either way it aligns with the platform's enterprise subscription model, which means a commitment to the CrowdStrike ecosystem. See vendor for a quote.
Secably provides a free tier offering instant tools like a free website vulnerability scanner, free port scanner, and SSL/TLS certificate checker without requiring signup. Paid monitoring plans start at $19/month, offering continuous external attack surface visibility. This makes Secably highly accessible for individuals, startups, and budget-conscious teams.
Features
Detectify excels in deep DAST capabilities, driven by its in-house security research and crowdsourced researcher community. It discovers unknown assets like subdomains and cloud storage buckets, then performs extensive vulnerability scanning. Its payload-based testing often uncovers issues public scanners miss. The platform is focused on web application and external attack surface security.
Tenable's ASM provides broad asset discovery across internet-facing IPs, domains, and cloud environments. It correlates external findings with data from its wider vulnerability management platform, and Nessus plugins cover a large range of checks. Its strength lies in covering the entire attack surface — external and internal — from a single vendor.
Intruder specializes in continuous external vulnerability scanning. It combines web application checks with network infrastructure scanning, running scheduled and event-driven scans that alert users to new vulnerabilities or attack-surface changes. It covers common web vulnerabilities, missing patches, and misconfigurations.
CrowdStrike Falcon Surface focuses on external attack surface discovery and threat intelligence rather than active DAST. It maps an organization's internet-facing assets — domains, IPs, certificates, and exposed services — and enriches them with threat intel, prioritizing risks based on active exploitation or known adversary targeting. It gives a clear overview of external exposure.
Secably offers continuous external attack surface monitoring, combining asset discovery with vulnerability scanning. It identifies subdomains, open ports, and web technologies, then scans those assets for common vulnerabilities and misconfigurations. Users receive prioritized, actionable findings. Secably also provides DNS lookup and HTTP security headers checker tools. Read more about its approach in External Attack Surface Management Explained.
Ease of Use
Detectify generally offers a clean, intuitive interface. Setting up scans and managing assets is straightforward, and reports are detailed with clear remediation guidance and proof-of-concept examples. The research-driven approach aims to keep false positives low.
Tenable is powerful but has a steeper learning curve given its extensive feature set and configuration options. Navigating its modules and advanced settings takes some training, and reporting is comprehensive but often needs customization to surface specific insights. It targets experienced security teams.
Intruder prioritizes simplicity. Its dashboard gives a clear overview of scan results and discovered vulnerabilities, continuous scans are easy to set up, and reports are concise and actionable — suitable for teams without dedicated vulnerability management specialists.
CrowdStrike Falcon Surface lives inside the broader Falcon console, offering a consistent experience for existing CrowdStrike users. The interface centers on risk prioritization and a visual view of the external attack surface. New users may need time to learn the Falcon platform layout.
Secably features a clean, modern interface built for quick setup and immediate insight. Its free tools need no account and return instant results, while the paid monitoring platform offers an intuitive dashboard with prioritized findings. Secably focuses on practical utility for practitioners.
API/Integrations
Detectify provides a documented REST API for automating asset management, triggering scans, and retrieving results. It integrates with issue trackers like Jira and with SIEM systems, and webhooks support custom notifications and workflows.
Tenable offers an extensive, well-documented API for automating almost any task in the platform, plus a broad range of pre-built integrations with SIEMs, IT asset management (ITAM) systems, CMDBs, and DevOps tools. Its enterprise focus means wide compatibility with existing security stacks.
Intruder offers an API for integrating with other tools and automating workflows, with direct integrations for Slack notifications and Jira ticket creation. Webhooks allow flexible integration with custom scripts or other platforms, and the API supports managing targets and retrieving scan data programmatically.
CrowdStrike Falcon Surface integrates deeply within the Falcon platform, giving unified visibility across EDR, XDR, and EASM. It provides an API for external integrations with SIEMs, SOAR platforms, and other tools, with its strongest integration story inside the CrowdStrike ecosystem.
Secably offers a REST API for managing assets, triggering scans, and retrieving vulnerability data. It supports webhooks for real-time notifications, enabling integrations with tools like Slack, Jira, or custom alerting systems, so teams can fold Secably's findings into existing workflows.

Verdict
Choosing among Detectify alternatives depends heavily on your team's size, budget, and specific security requirements.
For large enterprises with substantial budgets and complex, hybrid environments, Tenable offers deep integration between its ASM and broader vulnerability management, suiting organizations that want a single pane of glass for both external and internal risk. Teams already invested in the CrowdStrike Falcon platform will find Falcon Surface a natural extension for EASM, benefiting from unified threat intelligence and response.
Organizations prioritizing deep, research-driven DAST and crowdsourced vulnerability discovery, and with the budget for a premium modular solution, will find Detectify a strong contender. Its focus on advanced web application security is a key differentiator.
Mid-market companies and SMBs seeking continuous external vulnerability scanning with easy setup and clear, published pricing should consider Intruder. It provides solid scanning without the complexity or commitment of enterprise-grade platforms.
Secably serves individuals, startups, and small-to-medium teams looking for an accessible, affordable entry into continuous external attack surface management. Its free tools deliver immediate utility, and paid plans start at $19/month.
