Updates, insights, and guides on security testing and Scryn.
Testing webhooks and asynchronous callbacks with DAST
Learn how automated DAST detects SSRF and payload injection flaws in asynchronous webhooks and callback endpoints across CI/CD and staging environments.
Testing API rate limits and resource exhaustion with DAST
Learn how to test API rate limits and resource exhaustion using automated DAST without crashing staging environments. Practical guide for DevSecOps teams.
Testing Private Microservice APIs With Local DAST Agents
Learn how to deploy local DAST scan agents to test private microservices behind corporate firewalls before exposing them to external ingress.
Integrating API DAST Results into Enterprise Vulnerability Management Systems
Learn how to integrate API DAST results from CI/CD into enterprise vulnerability management systems for centralized visibility, risk-based prioritization, and streamlined remediation.
Validating API Gateway Security with DAST
Use DAST to confirm your API gateway actually blocks the attacks it should—covering misconfigurations, auth bypass, and OWASP Top 10 risks at the edge.
Handling Complex API Authentication for DAST Scans
Configure DAST for OAuth, MFA, and multi-step API logins: token injection, refresh flows, Auth Recorder, staging test users, and CI/CD integration.
Uncovering Broken Object Level Authorization (BOLA) in APIs with DAST
How DAST finds Broken Object Level Authorization (BOLA) in APIs: multi-user testing, ID manipulation, CI/CD integration, and prevention practices.
Building a Continuous API Security Feedback Loop: From Spec to Scan to Fix
How to build a continuous API security feedback loop: secure design from the spec, automated DAST scanning in CI/CD, risk-based triage, and regression testing to keep APIs secure across every release.
API Security Testing for Serverless Functions with DAST
How to test APIs behind Lambda, Azure Functions, and Cloud Functions with DAST: HTTP ingress, auth, scanning in CI/CD, and common pitfalls. See how Scryn can help.
API Security Testing in Serverless Environments: Best Practices
How to test APIs behind Lambda, Azure Functions, and Cloud Functions with DAST: HTTP ingress, auth, OpenAPI coverage, and CI/CD automation.
API Security Testing for gRPC: How to Test gRPC APIs with DAST
How DAST fits gRPC security testing, common vulnerability classes (auth, validation, channels), and what changes compared to REST-first tooling.
API Security Testing for Microservices: How DAST Helps Secure Inter-Service Communication and Prevent Lateral Movement Attacks
Why microservices raise API risk, how DAST tests live APIs (OpenAPI, GraphQL, auth), and best practices to reduce lateral movement in CI/CD.
DAST and Threat Modeling: Validating Assumptions and Identifying New Attack Vectors
Learn how to combine threat modeling and DAST to validate assumptions, discover missed attack paths, and prioritize remediation with a repeatable security testing loop.
Using DAST for WAF Validation: Effective Protection?
Validate WAF rules with DAST: send realistic attack-style traffic through your firewall, interpret blocks vs. origin findings, and automate regression checks in CI/CD. Try Scryn.
DAST for regression testing: verify security fixes and prevent regressions
Use DAST to regression-test security fixes: retest patches, catch incomplete fixes, and automate verification in CI/CD. Practical steps with Scryn.
DAST vs. IAST: Choosing the Right Dynamic Security Testing Approach for Your SDLC
DAST or IAST? Learn the differences between dynamic and interactive application security testing and how to choose the best method for your SDLC.
API security testing without a pentest: what small teams can still do
No pentest budget? You can still test APIs seriously: spec-driven DAST, CI scans, dependency checks, OWASP-aligned triage—and when human testers still matter.
DAST in CI/CD: How to add security scanning to your pipeline
DAST in CI/CD: automate security scans from GitHub Actions, GitLab CI, Jenkins, or Azure Pipelines. API tokens, webhooks, staging vs production, blocking vs report-only gates.
API security testing with DAST: how to test REST and GraphQL APIs
How to test REST and GraphQL APIs with DAST: OpenAPI and GraphQL schema–driven scanning, what vulnerabilities DAST finds in APIs, and when to run it. Spec-driven API DAST vs crawl-based web scanning.
What is AI-powered security scanning? AI Agentic Scan vs DAST
AI-powered security scanning (AI Agentic Scan) uses an AI agent to explore your app and adaptively probe for XSS, SQL injection, and misconfigurations. Learn how it differs from OWASP ZAP, when to use both, and best practices.
OWASP Top 10 in practice: what each risk means and how DAST helps
OWASP Top 10 (2025) explained: what each risk means and how DAST helps you find and fix them. Covers injection, misconfiguration, access control, auth, and error handling.
What is DAST? A practical guide to Dynamic Application Security Testing
What is DAST? Dynamic Application Security Testing finds security issues by testing your running app or API. Learn how DAST works, DAST vs SAST, when to run it, and what it finds.
