The Detectify alternative
If you are comparing Detectify alternatives, OnScanner is a strong fit. Both scan from the outside with fresh results, but OnScanner covers more in a single pass: privacy and tracker analysis, email authentication, TLS and WAF posture, and CVE intelligence with EPSS and CISA KEV, plus a hosted MCP server and opt-in AI Findings. Here is an honest, source-linked comparison so you can decide for yourself.

TL;DR
Choose OnScanner when you want the widest fully automated single pass: live, never-cached scans with safe exploit verification and zero-day heuristics, EPSS and CISA KEV prioritization, deep technology and end-of-life detection, and 40+ privacy and tracker checks with email, TLS and WAF posture. Turn on AI Findings and it writes the executive summary, ranks your Top Risks, chains findings into MITRE ATT&CK attack paths, drafts remediation, and generates SOC 2, ISO 27001, GDPR, PCI-DSS and HIPAA compliance reports. Free tier and a hosted MCP server included.
Detectify is a great choice when crowdsourced vulnerability research is your priority: Detectify's tests come from its ethical hacker community, and its surface monitoring focuses on web application and subdomain exposure.

Why teams pick OnScanner
- Enterprise-grade coverage, fully automated: specialist engines for security, privacy, CVE, DNS, technology and infrastructure analysis run in parallel in a single live pass.
- Every scan is live and never cached, with safe active exploitation probes that verify what is actually exploitable and zero-day heuristics that flag unknown vulnerabilities before a CVE exists.
- Deep technology detection with patch-status and end-of-life flags, so you know exactly what is running and what is out of support.
- Exploit-aware prioritization: CVE and CPE matching enriched with EPSS scores and the CISA KEV catalog, so you fix what attackers actually use.
- Opt-in AI Findings: an executive summary, ranked Top Risks, and clear per-finding explanations with remediation your developers can act on.
- Vulnerability chaining: AI Findings links related results into real attack paths mapped to the MITRE ATT&CK kill chain.
- AI Compliance reports on demand: SOC 2, ISO 27001, GDPR, PCI-DSS and HIPAA assessments generated from your scan results.
- 40+ privacy, tracker, fingerprinting and consent checks plus email (SPF, DKIM, DMARC), TLS and WAF posture in the same pass.
- Continuous monitoring with scheduled scans and 24/7 change detection, plus a REST API and hosted MCP server on every plan, free tier included.
When Detectify fits
- You want tests sourced from a bug bounty style community: Detectify's Crowdsource researchers submit payload-based test modules that feed its scanner.
- You focus on subdomain exposure: discovery and monitoring of subdomains, takeover and DNS misconfiguration detection, plus crawling of custom apps behind login.
- You want self-serve rollout with a REST API, cloud connectors (AWS, GCP, Azure, Cloudflare), and an MCP server.
The short version: OnScanner covers more categories in a single pass, including privacy and consent, email posture, end-of-life detection, and opt-in AI compliance reports, from a free tier.
Pricing
OnScanner is self-serve with a free Starter tier and Professional at $60 per month. Detectify: EUR 0/yr platform fee (Starter) + unpublished per-asset fees; effectively custom beyond the platform fee (Annual platform-fee tiers (Starter EUR 0, Standard EUR 2,500, Professional EUR 5,000, Enterprise EUR 15,000) plus additional per-asset costs for added assets, domains, environments, and IP ranges (per-asset prices not published). PCI ASV scanning add-on at EUR 500/month. 2-week free trial and self-serve signup, no credit card required. Verified 2026-07-02.)
Frequently asked questions
Is OnScanner a good Detectify alternative?
Yes, if you want broader coverage in one scan. OnScanner runs live web vulnerability scanning alongside 40+ privacy and tracker checks, email SPF, DKIM and DMARC posture, TLS and WAF analysis, and CVE intelligence with EPSS and KEV. It also ships a hosted MCP server and opt-in AI Findings, and you can try it on a free Starter tier before deciding.
How is OnScanner different from Detectify?
Both scan from the outside with current results. The main difference is coverage per pass: OnScanner folds privacy, tracker and consent scanning, email and TLS posture, and opt-in AI compliance reports (SOC 2, ISO 27001, GDPR, PCI-DSS, HIPAA) into the same scan, so security and privacy come back together rather than from separate tools.
Can I try OnScanner before switching from Detectify?
Yes. OnScanner has a free Starter tier and self-serve signup with no sales call, so you can scan a target you own and compare the results side by side with your current tool before you move anything.
What does OnScanner cover beyond vulnerability scanning?
Privacy and tracker analysis across 40+ categories, consent and cookie behaviour, email authentication, TLS and certificate posture, WAF detection, and end-of-life software flags. Turn on AI Findings and it also summarizes results, chains them to the MITRE ATT&CK kill chain, and drafts multi-framework compliance reports.
