The short version

  • Only OWASP ZAP has a free tier, so it costs nothing to try first.
  • Each has a real cost: NEXGEN Asset Management pricing keys off asset count, so a routine GIS resegmentation that splits mains into more records can raise your subscription without adding a single user or work order.; 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: NEXGEN Asset Management covers Esri GIS integration, OWASP ZAP covers Intercepting proxy.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

NEXGEN Asset Management

  • A water utility that must show a board why a specific main is being replaced this year rather than nextnot OWASP ZAP
  • A city public works department consolidating a GIS asset inventory and a paper work order process into one systemnot OWASP ZAP
  • An airport authority tracking condition assessments across airside and landside assets with capital forecastingnot OWASP ZAP
  • A district that needs citizen service requests to become tracked work orders with an auditable historynot OWASP ZAP

OWASP ZAP

  • Adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handfulnot NEXGEN Asset Management
  • Manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per testernot NEXGEN Asset Management
  • Teaching developers what an attack against their own endpoint looks like, using a tool they can install themselvesnot NEXGEN Asset Management
  • Pre-release regression scanning of an internal application that would never justify a commercial DAST subscriptionnot NEXGEN Asset Management

Where each one falls short

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

NEXGEN Asset Management

  • Pricing keys off asset count, so a routine GIS resegmentation that splits mains into more records can raise your subscription without adding a single user or work order.
  • Nothing is published and the vendor is small, so the reference set you can call is limited and mostly Californian and North American public agencies.
  • The interface is dated compared with modern CMMS products, which hurts adoption among field crews who compare it to consumer apps on their own phones.
  • GIS integration is the product strength and also its dependency; agencies without a maintained ArcGIS asset layer face a data preparation project before NEXGEN is useful.
  • As a small vendor it carries acquisition risk, and in this segment acquisitions have repeatedly meant a product frozen while it is folded into a larger portfolio.

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

NEXGEN Asset Management: How is NEXGEN priced?

On a tiered model based on the number of assets under management, quoted per agency. Nothing is published.

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.

NEXGEN Asset Management: Do we need Esri ArcGIS?

Not strictly, but the product is designed around it and most of the value assumes a maintained GIS asset layer.

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.

NEXGEN Asset Management: Does it handle capital planning?

Yes. Risk, criticality and condition scores feed multi-year renewal forecasts intended for board and council submissions.

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.

NEXGEN Asset Management: Is there a mobile app?

Yes, a map-based field application with offline capability, licensed alongside the core platform.

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.
