The short version

  • Each has a real cost: Endor Labs pricing requires contacting sales, no transparent rates; OWASP ZAP authenticated scanning of modern single-page applications is the hard part and ZAP makes you build it by hand: session handling, token refresh and login scripts are configured per application, and a misconfigured session means the scanner logs itself out and reports a clean result for pages it never reached.
  • They diverge on capability: Endor Labs covers AI coding agent governance, OWASP ZAP covers Intercepting proxy.
  • Prices and features above were last checked on 30 August 2026.

OWASP ZAP

  • Teaching developers what an attack against their own endpoint looks like, using a tool they can install themselvesnot Endor Labs
  • Pre-release regression scanning of an internal application that would never justify a commercial DAST subscriptionnot Endor Labs

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Endor Labs

  • Pricing requires contacting sales, no transparent rates
  • Developer tier lacks UI and historical scan data
  • Free tier limited to local scanning only
  • Seat-based model may become expensive for large teams

OWASP ZAP

  • Authenticated scanning of modern single-page applications is the hard part and ZAP makes you build it by hand: session handling, token refresh and login scripts are configured per application, and a misconfigured session means the scanner logs itself out and reports a clean result for pages it never reached.
  • There is no support contract in the product, so when a scan breaks the day before a release the escalation path is a GitHub issue and a community chat, which is not an answer that satisfies a delivery manager or an auditor who wants a named responsible party.
  • Active scanning sends genuine attack traffic, so it can create records, trigger emails, exhaust rate limits or destabilise a fragile environment, and pointing it at production without prior agreement produces an incident rather than a test result.
  • Output needs triage: passive rules generate large volumes of low-severity informational findings about headers and cookie flags that bury the few results that matter, and a team without someone tuning the rule set stops reading the report within a few sprints.
  • As a dynamic scanner it can only test what it can reach, so authorisation flaws between accounts, business logic abuse and anything behind an undiscovered endpoint go unreported, and a passing ZAP scan is evidence of nothing more than the absence of the classes of bug it looks for.

Answered from the vendors’ own pages

Endor Labs: What is the difference between Endor Labs Developer and paid tiers?

Developer tier is free and provides local scanning via MCP server with read-only vulnerability access and no UI. Paid tiers (Core and Pro) add team features like policy enforcement, enterprise integrations, reporting, and scan history.

Source
OWASP ZAP: Is it still called OWASP ZAP?

The project left OWASP in August 2024 and is now governed by the Software Security Project, with core development sponsored by Checkmarx. The tool is now just ZAP, though most existing documentation, courses and search results still use the OWASP name.

Endor Labs: How does Endor Labs define seats for pricing?

Seats are calculated per contributing developer (those with commits in monitored repositories within the last 90 days). Volume discounts apply as team size grows.

Source
OWASP ZAP: Is it free for commercial use?

Yes. It is Apache 2.0 licensed, with no per-application, per-scan or per-user cost, and it can be used and modified commercially without a licence agreement.

Endor Labs: Does Endor Labs support on-premises deployment?

The platform is cloud-based SaaS by default. Enterprise customers should contact sales to discuss custom deployment options.

Source
OWASP ZAP: Can it replace a penetration test?

No. It automates checks for known vulnerability classes against endpoints it can reach. It does not reason about business logic, chain findings into an attack, or test authorisation between accounts, which is most of what a tester actually does.

OWASP ZAP: Does it run in CI?

Yes, through the official Docker images and the Automation Framework, which defines scan jobs in YAML so configuration lives in the repository. A baseline passive scan is the usual starting point because it is fast and non-intrusive.

OWASP ZAP: How does it compare to Burp Suite?

Burp Suite Professional is the more polished manual testing tool and has a stronger scanner and extension ecosystem, but it is licensed per tester and Burp Suite Enterprise per target. ZAP is the better fit where cost per target is the binding constraint; many teams use both.
