Quick take:
- In an environment with AI-generated code, security testing is not optional
- Traditional xAST tools fall short
- SAST reports too many false positives
- DAST can’t tell you why or where your code is buggy
- IAST in the runtime highlights accuracy and gives devs the context needed to avoid sending vulnerable & exploitable code into production
If you ask a developer why they hate security testing, you’ll usually get two answers.
The first is the “SAST Avalanche.” They commit their code, wait for the CI/CD pipeline to clear, and are immediately buried under hundreds of alerts – only to realize the majority are false positives. The remaining alerts are likely informational only and are not exploitable in practice.
The second answer is the “DAST Black Box.” Security teams run a dynamic scanner that blindly hammers the application from the outside for 12 hours. When the report finally arrives three days later, it’s vague. It tells the developer something broke on page 4, but it can’t tell them why, or where in the code the vulnerability lives. It lacks context. It’s too slow, too detached from the code, and too superficial to handle modern, complex architectures.
For years, DevSecOps teams have been forced to choose between these two extremes, drowning in noise or flying blind. Now, with AI-generated code and sprawling microservices, you can no longer afford tools that lack context and guesstimate. You need a tool that has both context and uncovers the truth.
Current toolkits fail the “Goldilocks” test; Waratek IAST is the “just right” solution you’ve been waiting for.
| Feature | SAST (Static Analysis) | DAST (Dynamic Analysis) | Waratek IAST |
| How it Works | Scans source code at rest (like a spellchecker). | Attacks the running application from the outside (like an attacker). | Monitors the application from the inside while it runs (like an X-ray). |
| False Positive Rate | High. Flags theoretical risks that may never be executable (e.g., “dead code”). | Low/Medium. Only reports what it can exploit, but often guesses wrong on complex logic. | Near Zero. Only flags vulnerabilities on actually executed paths and verified their exploitability. |
| Microservices & APIs | Limited. Sees code in isolation; cannot validate cross-service data flows. | Poor. Struggles to crawl modern APIs (GraphQL, gRPC) or reach backend services behind gateways. | Full Visibility. Has all the runtime context, such as full request details across services. |
| Configuration Effort | High. Requires extensive rule tuning to reduce noise. | Very High. Needs login scripts, crawl configurations, and special network permissions. | Zero Config. Piggybacks on existing QA/functional tests automatically. No “tuning” required. |
| 3rd Party Libraries | Version Checking. At best, it checks package versions against a CVE database (SCA). | Blind. Cannot see internal library usage unless it causes an external crash. | Runtime Usage. Identifies which vulnerable libraries are actually loaded and used, filtering out unused components or dead code and false alarms. |
| Speed & Pipeline Impact | Fast but Noisy. Can break builds with thousands of alerts, causing “alert fatigue.” | Slow. Scans can take hours or days; usually run out-of-band (e.g., weekly), delaying feedback. | Real-Time. Runs at the speed of your automated tests. Feedback is instant for the developer. |
| Remediation Advice | Generic. “Critical: possible SQL injection in UserService.java:123. Untrusted request parameter is concatenated into SQL string. Needs manual review. | Vague. “URL returned 500 Error.” (Developer has to hunt for the root cause). | Precise. “Critical: Confirmed SQL injection on POST /login with payload originating from parameter ‘name’. Taint flow observed from HTTP parameter → UserService.buildQuery → Statement.executeQuery at UserService.java:123. HTTP request replayable as PoC. Detailed remediation steps and sample PR are provided.“ |
Waratek IAST is the solution that answers the questions created by SAST and DAST by monitoring and analyzing the code like a white-box tool but validates the execution like a black-box solution.
