**OWASP ZAP is free. Burp Suite Pro is $449 per user per year. That price difference is real, and for a lot of teams it's the entire conversation. But price alone doesn't tell you which tool will actually find the bugs that matter in your application.**
Both tools are web application security proxies. Both intercept HTTP traffic, spider web applications, and run automated scans for common vulnerabilities. Both have been around for over a decade. And both have loyal communities that will tell you the other tool is unnecessary.
This article compares them honestly — feature by feature, workflow by workflow — so you can make the decision based on what your team actually needs rather than what a vendor landing page tells you.
## Key Takeaways
- SQL injection remains the most exploited injection flaw in web applications
- Both error-based and boolean-based detection methods are needed for full coverage
- Reflected XSS requires testing every user-controlled input that appears in responses
- Automated scanners miss vulnerabilities that require multi-step or context-aware testing
- OWASP Top 10 provides the baseline — real-world testing goes beyond the checklist

## 2. Automated Scanning: Where the Gap Shows
Both tools scan for the OWASP Top 10. Both will find reflected XSS, SQL injection, directory traversal, and missing security headers. For the standard vulnerability classes, the detection rates are closer than most people expect.
Where Burp pulls ahead is in **scan intelligence**. Burp's scanner has better handling of:
- **Authentication state** — Burp's session handling rules and macros make it easier to maintain authenticated scans across complex login flows. ZAP can do this, but the configuration is more manual and more fragile.
- **JavaScript-heavy applications** — Burp's browser-powered crawl handles SPAs and client-side routing more reliably than ZAP's AJAX Spider, which can miss routes that require specific user interactions.
- **Scan speed and tuning** — Burp's scan configurations are more granular. You can target specific insertion points, skip specific checks, and tune the scan to your application's behaviour. ZAP's scan policies are configurable but less fine-grained.
- **False positive rate** — Burp's scanner generally produces fewer false positives, particularly for DOM-based XSS and blind injection variants. This matters when you're triaging hundreds of findings.
ZAP's scanner is not bad — it's genuinely capable and improving with every release. But if scanning accuracy is your primary concern and you're testing complex, authenticated web applications, Burp's scanner is the stronger tool.
## 3. Manual Testing and Interception
For manual testing — intercepting requests, modifying parameters, replaying requests — both tools are excellent. This is the core proxy workflow, and both have had over a decade to refine it.
**Burp's advantages:**
- **Repeater** is best-in-class for request manipulation. The interface is clean, tabbed, and fast.
- **Comparer** makes it easy to diff responses side-by-side — useful for identifying subtle differences in authentication bypass attempts.
- **Collaborator** provides out-of-band interaction detection (DNS, HTTP, SMTP) — essential for blind SSRF and blind XXE testing. ZAP has no built-in equivalent.
**ZAP's advantages:**
- **HUD (Heads Up Display)** overlays security information directly in the browser — useful for developers who want to see vulnerabilities in context without switching to a separate tool.
- **Requester** add-on provides similar functionality to Burp's Repeater, though the UX is less polished.
- **Break points** work well for intercepting and modifying specific requests based on conditions.
The Collaborator gap is significant. If you're doing serious manual penetration testing — especially for SSRF, blind injection, or out-of-band data exfiltration — Burp's Collaborator is a capability ZAP simply doesn't match without external tooling.
## 4. Extensibility and Ecosystem
Both tools support extensions, and both have active communities building them.
**Burp's BApp Store** has a larger selection of professionally maintained extensions. Popular BApps like Autorize (authorization testing), Logger++ (advanced logging), and Param Miner (hidden parameter discovery) are well-maintained and widely used. Many BApps are written by professional pentesters and security researchers.
**ZAP's Marketplace** is smaller but growing. The community-contributed add-ons cover most common use cases. ZAP's scripting engine is more flexible — you can write custom scan rules, authentication handlers, and HTTP senders in Python, JavaScript, or Zest (a graphical scripting language designed for security testing).
For teams that want to write custom tooling, ZAP's open-source nature is a significant advantage. You can fork it, modify the core, contribute upstream, and build internal extensions without licensing constraints. With Burp, you're limited to the extension API — which is capable, but you can't modify the core scanner or proxy behaviour.
## 5. CI/CD Integration
This is where ZAP has a clear structural advantage.
**ZAP** ships official Docker images, GitHub Actions, and a full CLI (zap.sh) that can run headless scans, generate reports, and fail builds based on alert thresholds. You can add ZAP to a CI/CD pipeline in an afternoon with zero licensing cost. The [ZAP Automation Framework](https://www.zaproxy.org/docs/automate/) provides YAML-based scan configuration that's version-controllable and reproducible.
**Burp Suite Pro** has no native CI/CD integration. You can script it via the REST API or use community tools, but it's not designed for headless pipeline use. **Burp Suite Enterprise** ($3,999+/yr) adds CI/CD integration with Jenkins, GitHub Actions, and GitLab CI — but that's a separate product at a separate price point.
If your primary use case is "scan every PR automatically and block merges with high-severity findings," ZAP does this out of the box for free. Burp requires Enterprise licensing to match it.
## 6. Team Workflows and Collaboration
Neither tool excels at collaboration in its base form.
**ZAP** stores sessions locally. Sharing findings means exporting reports (HTML, XML, JSON, Markdown) and distributing them manually. There's no shared dashboard, no centralised findings database, and no built-in way for multiple testers to work on the same target simultaneously.
**Burp Suite Pro** has the same limitation — project files are local, and sharing requires manual export. **Burp Enterprise** solves this with a centralised web dashboard, shared scan results, and team-level reporting. But again — that's the $3,999+/yr tier.
For teams that need centralised vulnerability management, both tools typically feed into a separate platform — DefectDojo, Faraday, or a custom SIEM integration. ZAP's open formats (JSON, XML) make this integration straightforward.
## 7. When ZAP Is the Right Choice
- **Budget is zero.** ZAP is genuinely free — no feature gates, no user limits, no trial expirations. For startups, students, and teams without a security tool budget, this is the entire argument.
- **CI/CD-first security.** If your primary goal is automated scanning in pipelines, ZAP's Docker images and Automation Framework are purpose-built for this. No licensing complexity.
- **Developer-facing security.** ZAP's HUD and simpler interface make it more approachable for developers who aren't full-time security practitioners. It's a good "shift-left" tool.
- **Custom tooling.** If you need to modify scanner behaviour, write custom scan rules, or integrate deeply with internal systems, ZAP's open-source codebase gives you full control.
- **API security testing.** ZAP's OpenAPI import and API scan profiles work well for teams focused on REST API security. The automation framework makes it easy to script API-specific scan configurations.
## 8. When Burp Suite Is the Right Choice
- **Professional penetration testing.** If your team does manual pentesting as a primary activity, Burp's Repeater, Collaborator, and Intruder are best-in-class. The workflow is faster and more polished.
- **Complex authenticated applications.** Burp's session handling, macro recording, and authentication state management are more robust for applications with complex login flows, CSRF tokens, and multi-step authentication.
- **Scan accuracy matters most.** Burp's scanner produces fewer false positives and handles JavaScript-heavy applications more reliably. If you're triaging findings at scale, this saves real time.
- **You need Collaborator.** Out-of-band interaction detection is a capability gap that ZAP doesn't fill natively. For blind SSRF, blind XXE, and DNS-based data exfiltration testing, Collaborator is essential.
- **Enterprise-scale scanning.** Burp Enterprise provides centralised scanning, team dashboards, and CI/CD integration in a managed package. If you have the budget and need a turnkey solution, it's well-executed.
## 9. The Verdict
There's no universal winner. The right tool depends on your team's workflow, budget, and primary use case.
**Use ZAP if** you need a free, CI/CD-friendly scanner that developers can run without a license. It's the best open-source web security tool available, and for automated pipeline scanning, it's arguably better than Burp Pro (not Enterprise).
**Use Burp Suite Pro if** your team does manual penetration testing and needs the best possible manual testing workflow. At $449/yr per user, it's a reasonable investment for professional pentesters.
**Use both** if you can. Many security teams run ZAP in CI/CD pipelines for automated coverage and use Burp Pro for manual testing engagements. The tools complement each other well — ZAP catches the baseline, Burp goes deeper on manual investigation.
