External attack surface & web scanning · Alternatives
The Best Detectify Alternatives in 2026
Detectify pairs external attack surface discovery with web scanning powered by a crowdsourced library of payloads from ethical hackers. It is strong at telling you what you have exposed and whether known issues apply to it. Teams tend to look elsewhere when they need deeper testing of the applications themselves, developer-pipeline integration, or a different price-to-scope fit.
Why teams look for Detectify alternatives
- ›Detectify scans for known vulnerability patterns; it does not exploit findings or prove attack paths
- ›Authenticated, role-aware testing of application logic is not its core strength
- ›Broken access control and IDOR, the most common critical class, need adversarial testing, not signatures
- ›Annual subscription pricing can be high relative to the depth of findings for small teams
- ›You want findings in pull requests and testing on every deploy, not a monitoring dashboard
6 best Detectify alternatives
Penetrify
Editor's pickAn autonomous AI penetration testing platform that attacks running web applications and APIs like an adversary: it maps the attack surface, tests authentication and authorization, and chains findings into multi-step exploits. It returns a structured report in minutes and runs on every deploy via CI/CD.
Intruder
A cloud-based vulnerability scanner focused on ease of use, continuous external scanning, and noise reduction for smaller security teams.
Acunetix
A commercial DAST scanner for automated detection of web vulnerabilities across large application portfolios, with crawling for JavaScript-heavy apps.
StackHawk
A developer-first DAST tool that runs in CI/CD, driven by API specs (OpenAPI/GraphQL), with findings surfaced in pull requests.
OWASP ZAP
A free, open-source DAST proxy and scanner maintained by the OWASP community.
Qualys VMDR
A cloud-based vulnerability management platform with broad asset coverage and continuous monitoring. A fit when external discovery needs to extend to full enterprise VM.
Surface Monitoring vs. Application Testing
Detectify's home turf is the outside view: what domains, services, and endpoints you expose, and whether known payloads land on them. Intruder and Qualys compete on that same axis with different scale points, and ZAP or Acunetix cover the classic DAST angle.
Penetrify starts where surface monitoring stops. It logs in, tests what each role can reach, attempts exploitation, and chains findings, which is the work a human pentester does after the recon phase. The two layers complement each other, but if you can only fund one and you ship application code weekly, depth on the application usually pays more than another view of the surface.
What to Pick by Priority
Keep the surface-monitoring model with a cheaper footprint: Intruder. Free scanning: OWASP ZAP. Developer-owned DAST in the pipeline: StackHawk. Enterprise consolidation: Qualys.
If the gap that sent you looking is "our scanner never finds the things our pentest finds," that is Penetrify's exact category: autonomous exploitation-driven testing from $100/month, on every deploy.
The verdict
Intruder is the closest swap if you want the same surface-scanning model at a smaller price point; StackHawk moves scanning into the developer pipeline, and ZAP does it for free. Penetrify is the depth upgrade: instead of matching payloads against your surface, it runs a real penetration test (authorization, IDOR, business logic, exploit chaining) continuously, from $100/month.
Frequently asked questions
What is the closest alternative to Detectify?
Intruder is the closest like-for-like alternative for continuous external vulnerability scanning, with Qualys VMDR at enterprise scale. For deeper application testing (real exploitation rather than payload matching), Penetrify runs autonomous AI penetration tests from $100/month.
Does Detectify do penetration testing?
Detectify automates web scanning using payloads sourced from ethical hackers, but it is still signature-driven scanning. It does not autonomously exploit findings, chain attack paths, or test role-based authorization. For that depth you need a penetration testing platform such as Penetrify.
What should replace Detectify for API security?
For spec-driven API scanning in CI, StackHawk is a strong choice. For adversarial API testing that covers authorization flaws, IDOR, and business logic across REST and GraphQL, Penetrify tests running APIs the way an attacker would and reports proven findings with reproduction steps.
