Detectify vs Acunetix is a common comparison for AppSec teams evaluating Dynamic Application Security Testing (DAST) tools.
This article provides a direct comparison between Detectify and Acunetix, focusing on key challenges such as attack surface visibility, vulnerability assessment methodology, and time to value. It is intended for security teams evaluating DAST solutions or researching an Acunetix alternative.
Acunetix (part of the Invicti family since 2017) has been part of the DAST world for 20 years, known for its deep code-level internal scanning capabilities. Detectify, on the other hand, is built on a more forward-looking approach. It combines its proprietary, payload-based scanning engine and a multi-source intelligence model, powered by a private community of elite ethical hackers (Detectify Crowdsource), an AI researcher, and an internal team, enabling it to also find the novel, non-CVE vulnerabilities that are often missed by other tools.
This comparison is based on feedback from prospective customers, evaluations by teams previously using Acunetix, and publicly available documentation and demos from Acunetix:

Acunetix assumes you already know what you need to scan. It is built as a target-based scanner where you provide the URL, and it goes to work. Acunetix’s focus remains on the bottom-up approach; once a target is identified, it crawls every corner. For teams with a strictly defined and static perimeter, this works really well. However, it often misses the shadow IT created by developers spinning up staging environments or marketing teams launching microsites.
Detectify treats discovery as a continuous, automated process. It doesn’t wait for you to tell it what to scan; it uses an outside-in approach to map your entire attack surface. It identifies subdomains and IPs that you might have missed. Detectify can provide intelligent scan recommendations, highlighting newly discovered high-risk assets and ensuring your security coverage grows as quickly as your infrastructure. Acunetix is a spotlight, shining brightly on whatever you point it at, however Detectify is a floodlight illuminating the entire room, providing visibility into subdomains, forgotten assets, and the broader external attack surface.
Acunetix is known for IAST (Interactive Application Security Testing) technology. By placing an agent inside the application, it can see the source code being executed. This allows it to pinpoint the exact line of code where a vulnerability exists. It is exceptionally strong at finding vulnerabilities in legacy applications and complex CMS platforms like WordPress. However, because it relies heavily on these internal signatures, it can sometimes produce noise that requires manual triage, therefore taking more time and maintenance.
Detectify takes a “hacker-first” approach. Instead of just looking for signatures, it uses 100% payload-based testing, executing non-destructive attacks to see if a vulnerability is actually exploitable. Much of its security logic comes from its Crowdsource community, with more than 400 elite ethical hackers who provide Detectify with novel exploits and 0-days long before they hit a CVE database. This is paired with Alfred, an AI security researcher that converts new vulnerability disclosures into assessments fully autonomously. Acunetix helps developers find the line of code to fix. Detectify tells you exactly how an attacker would break in, often using flaws that haven’t been publicly documented yet.
Acunetix offers a high degree of granular control and for users who need to customize every scan parameter or deploy the tool on-premise to reach internal networks, Acunetix is the go-to. However, this flexibility requires significant configuration. Setting up authenticated scans and managing the volume of findings can be a full-time job for an AppSec engineer.
Detectify is built for modern, fast-moving teams that don’t have time for manual triage. It prioritizes a low signal-to-noise ratio. Because vulnerabilities are payload-verified, the findings are delivered with high confidence, a low false positive rate and reproducible evidence. This allows security teams to automate the workflow: Detectify finds it, verifies it, and pushes it directly into Jira or Slack, allowing the engineer to act as a facilitator rather than a manual tester. Acunetix is a powerful manual tool for the deep-dive specialist. Detectify is a streamlined automation engine for the team that needs to scale.
The core difference between Acunetix and Detectify is based on your team’s approach to application security and attack surface management. Acunetix offers a toolset that is ideal for teams needing deep technical insights on a fixed set of applications and an understanding of what domains are under their purview. In contrast, Detectify is a DAST solution that uses 100% payload-based testing, allowing security teams to stay ahead of emergent threats. While Acunetix is a good fit for organizations requiring on-premise deployments, Detectify’s payload-based engine and Detectify Crowdsource community deliver a high-fidelity signal of confirmed, exploitable findings. This allows AppSec teams to bypass the noise of theoretical CVEs, find novel, non-CVE flaws, and focus on remediating the vulnerabilities that actually matter across their entire attack surface.
