ZeroThreat is an AI-powered DAST and automated penetration testing platform founded in 2023 and launched at Web Summit 2024. The platform scans web applications and APIs for over 40,000 vulnerabilities including OWASP Top 10 and CWE Top 25, with support for REST, SOAP, GraphQL, and gRPC endpoints from a single interface. ZeroThreat claims 98.9% detection accuracy with near-zero false positives, achieved through AI-driven validation that confirms whether detected vulnerabilities are actually exploitable. The platform includes business logic testing for BOLA, IDOR, and access control flaws that rule-based scanners typically miss. CI/CD integrations cover GitHub Actions, GitLab, Jenkins, Azure DevOps, CircleCI, Bamboo, and TeamCity.
Fluid Attacks takes a hybrid approach that combines continuous automated scanning with manual ethical hacking performed by a team of certified security researchers. The platform covers SAST, DAST, SCA, and CSPM in a single solution, with the distinguishing feature being human-verified penetration testing layered on top of automated scanning. This combination catches vulnerabilities that purely automated tools miss, particularly complex business logic flaws and chained attack vectors. Fluid Attacks provides a continuous hacking model where their security team actively tests your applications throughout the development lifecycle rather than performing one-time assessments.
Checkmarx is the enterprise AppSec market leader, recognized as a Leader in the Gartner Magic Quadrant for Application Security Testing. The platform provides a comprehensive suite covering SAST with Checkmarx One, DAST, SCA for open-source risk management, API security testing, and supply chain security. Checkmarx supports over 30 programming languages and integrates deeply with enterprise CI/CD pipelines, IDEs, and issue trackers. The platform serves some of the largest enterprises globally with SOC 2 Type II certification, on-premise deployment options, and comprehensive compliance reporting for regulated industries.
The market positioning of these three tools targets fundamentally different buyer profiles. ZeroThreat serves small to mid-sized teams that need affordable, developer-friendly DAST with automated pentesting capabilities they can run continuously without hiring dedicated security staff. Fluid Attacks serves organizations that require human-verified security testing as part of their compliance or risk management requirements. Checkmarx serves large enterprises that need a comprehensive AppSec platform covering every testing methodology under one contract with dedicated support and SLA guarantees.
Testing methodology is where the differences become most consequential. ZeroThreat's Automated Pentesting Engine simulates real attacker behavior by chaining multi-step exploits and validating findings through active exploitation. This goes beyond traditional DAST payload injection by dynamically adapting scan strategy based on observed application behavior. Fluid Attacks layers human intelligence on top of automated scanning, with certified ethical hackers manually testing for complex vulnerabilities that automation cannot reliably detect. Checkmarx provides comprehensive automated scanning across SAST and DAST but relies primarily on algorithmic detection without the manual verification layer.
