Best Dynamic Application Security Testing (DAST) Software for Linux

Secure your stack with Aikido's code-to-cloud security platform. Find and fix vulnerabilities fast & automatically. Aikido’s DAST scanner shows where your app is most vulnerable so you can close security gaps before attackers find them. Monitor your App & APIs to find vulnerabilities like SQL injection, XSS, and CSRF — both on the surface and via authenticated DAST.

Application security is noisy and overly complicated. The good news: you can relieve that unnecessary noise and dramatically reduce your risk of attacks with Invicti. Keeping up with security is more manageable with accurate, automated testing that scales as your needs shift and grow. That's where Invicti shines. With a leading dynamic application security testing solution (DAST), Invicti helps teams automate security tasks and save hundreds of hours each month by identifying the vulnerabilities that really matter. Combining dynamic with interactive testing (DAST + IAST) and software composition analysis (SCA), Invicti scans every corner of an app to find what other tools miss. With asset discovery, it's easier to discover all web assets — even ones that are lost, forgotten, or created by rogue departments. Through tried-and-true methods, Invicti helps DevSecOps teams get ahead of their workloads to hit critical deadlines, improve processes, and communicate more effectively.

HCL AppScan is a unified application security platform that automates vulnerability detection, testing, triage, and remediation across code, applications, APIs, and LLMs. It combines DAST, SAST, IAST, SCA, API, IaC, and Secrets capabilities with centralized risk visibility, reporting, and compliance. Integrated with IDEs and DevOps workflows, AppScan uses AI-assisted analysis and agentic fix recommendations to help teams prioritize risks, accelerate remediation, strengthen AI code security, and build verifiable trust into every release.

Invicti Web + API, formerly Acunetix, is a dynamic application security testing (DAST) platform for identifying and validating vulnerabilities across web applications, APIs, and other runtime assets. The platform automatically discovers applications, APIs, shadow assets, unlinked pages, and undocumented endpoints while supporting modern JavaScript applications and authenticated workflows. Its scanning engine detects more than 7,000 types of security issues, including vulnerabilities covered by the OWASP Top 10 and OWASP API Top 10 as well as business logic flaws. Invicti combines AI-driven risk scoring with runtime reachability, exploitability, and business context to help security teams prioritize vulnerabilities that represent demonstrable risk.

Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efficiencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.

DerScanner is a convenient and easy-to-use officially CWE-Compatible solution that combines the capabilities of static (SAST), dynamic (DAST) and software composition analysis (SCA) in a single interface. It helps provide more thorough control over the security of applications and information systems and check both your own and open source code using one solution. Correlate the results of SAST and DAST, verify the detected vulnerabilities and eliminate them as a first priority. Strengthen your code by fixing vulnerabilities in both your own and third-party code. Perform an independent code review with developers-agnostic application analysis. Detect vulnerabilities and undocumented features in the code at all stages of the application development lifecycle. Control your in-house or third-party developers and secure legacy apps. Enhance user experience and feedback with a smoothly working and secure application.

Safeguard is an AI-native software supply chain security platform that discovers vulnerabilities, determines which ones are actually reachable, and can autonomously create and merge fixes. Its Griffin AI system analyzes repositories, containers, dependencies, SBOMs, and call graphs to prioritize exploitable issues instead of overwhelming teams with every detected CVE. The platform can generate remediation pull requests, run CI and regression tests, apply policy gates, and update security attestations after a fix is completed. Safeguard also includes zero-day discovery, runtime protections for AI applications, compliance automation, hardened software components, and support for hundreds of regulatory and security frameworks. Developers and AI agents can interact with the platform through its MCP server, APIs, IDE tools, source-control integrations, and CI/CD connections.

ThreatSpy by Secure Blink is an autonomous DAST and API security testing platform that runs 24x7 continuously without requiring a human trigger. Every finding passes through a dedicated AI Review layer that validates exploitability and business impact before surfacing to the developer queue — delivering 90%+ reduction in false positives. Remediation Campaigns and Automated Playbooks close the loop from detection to verified fix, auto-creating tickets in Jira, Trello, and ServiceNow on detection. Key capabilities: Continuous autonomous DAST, REST, GraphQL, OpenAPI and Postman Collection API security testing, OWASP Top 10, OWASP API Top 10 and SANS CWE Top 25 coverage, AI Review per finding, Scan Comparison across releases, CI/CD integration with Jenkins, GitHub Actions, GitLab CI, Bitbucket, Azure DevOps and CircleCI, SaaS, Private Cloud and On-Premises deployment. Rated 4.7/5 on G2. GrindStone Award winner RSA 2026. Free 14-day trial. No credit card required.

OWASP ZAP (Zed Attack Proxy) is a free, open-source penetration testing tool being maintained under the umbrella of the Open Web Application Security Project (OWASP). ZAP is designed specifically for testing web applications and is both flexible and extensible. At its core, ZAP is what is known as a “man-in-the-middle proxy.” It stands between the tester’s browser and the web application so that it can intercept and inspect messages sent between browser and web application, modify the contents if needed, and then forward those packets on to the destination. It can be used as a stand-alone application, and as a daemon process. ZAP provides functionality for a range of skill levels – from developers, to testers new to security testing, to security testing specialists. ZAP has versions for each major OS and Docker, so you are not tied to a single OS. Additional functionality is freely available from a variety of add-ons in the ZAP Marketplace, accessible from within the ZAP client.

Tired of high level malware analysis? Perform one of the deepest analysis possible - fully automated or manual - from static to dynamic, from dynamic to hybrid, from hybrid to graph analysis. Rather than focus on one, use the best of multiple technologies including hybrid analysis, instrumentation, hooking, hardware virtualization, emulation and machine learning / AI. Check out our reports to see the difference. Deeply analyze URLs to detect phishing, drive by downloads, tech scam and more. Joe Sandbox uses an advanced AI based algorithm including template matching, perptual hashing, ORB feature detection and more to detect the malicious use of legit brands on websites. Add your own logos and templates to extend the detection capabilities. Interact with the sandbox through Live Interaction - directly from your browser. Click through complex phishing campains or malware installers. Test your software against backdoors, information leakage and exploits (SAST and DAST).
