This guide will explore the key distinctions between Nessus and Detectify, two products built to solve different problems. We’ll compare their core visibility, assessment methodologies, and approaches to modern web apps and API security.


The primary difference between the two products lies in their core focus. Nessus focuses on infrastructure vulnerability scanning, where they have prioritized  performing deep, authenticated scans on internal assets like servers and workstations. Nessus’ strength is its massive plugin library, which is ideal for patch management and compliance auditing. However, its web application scanning is a newer, less specialized feature, and its external scans are signature-based, which can create a high volume of false positives and triage work for an Application Security team.


Detectify, in contrast, starts with giving users both the visibility and context about their attack surface, making it possible to test each and every asset, like modern web applications and APIs. Its key technical differentiator is its payload-based testing methodology, API scanner, and classification and recommendation system. By confirming exploitability with every finding, it reduces false positives and curbs the triage load. Detectify’s assessment capabilities are further enhanced by sourcing vulnerabilities from a private community of ethical hackers and an AI agent, allowing it to find novel and non-CVE issues.


Detectify vs. Nessus: A Quick Comparison


We’ve built this comparison mainly based on the feedback from dialogues with prospective clients and past Nessus users who decided to evaluate Detectify as its alternative, but also based on the following sources:



  • Nessus’ official website & resources

  • Nessus’ documentation

  • Nessus’ publicly accessible demos


TL;DR
