Invicti is an application security company headquartered in Austin, Texas, formed in 2018 when the Netsparker and Acunetix scanners came under one roof. Netsparker was created by Turkish security researcher Ferruh Mavituna, and the company still has an office in Turkey; the Netsparker product was folded into the Invicti brand in 2022. Its core is a dynamic application security testing (DAST) scanner that crawls running web apps and APIs and probes them from the outside.

The signature feature is proof-based scanning, which safely confirms many vulnerabilities, such as SQL injection, with evidence, cutting false positives and triage time. Web + API covers DAST, API discovery, stateful API testing, LLM security and CI/CD automation; AppSec Core adds SAST, SCA, container, IaC and secrets scanning with ASPM correlation; AppSec Flex adds on-premises or air-gapped deployment. These plans are quote-only, while Agentic Pentest costs up to $500 per pentest.

Invicti fits enterprises with large web app and API portfolios that need accurate, automated DAST in CI/CD. Snyk is stronger on developer-first code and dependency scanning, Burp Suite Professional is the favorite of manual pentesters, and Acunetix, from the same parent, is the lighter option for smaller teams.

In August 2025 Invicti acquired Istanbul-based Kondukto, an ASPM platform, to combine runtime-validated DAST findings with results from other scanners. Tip: run the PoC on a staging app with authentication configured, since login handling decides real coverage.
