The short version
- Only OWASP ZAP has a free tier, so it costs nothing to try first.
- Each has a real cost: 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.; Sophos Intercept X sophos publishes no price for endpoint protection: the product page names editions but gives no per user rate, no minimum seat count and no contract length, and routes buyers to a sales enquiry
- They diverge on capability: OWASP ZAP covers Intercepting proxy, Sophos Intercept X covers Deep learning AI.
- Prices and features above were last checked on 30 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
Sophos Intercept X
- Sophos publishes no price for endpoint protection: the product page names editions but gives no per user rate, no minimum seat count and no contract length, and routes buyers to a sales enquiry
- Extended detection and response requires the Advanced with XDR edition rather than the base endpoint product
- 24x7 monitored detection and response is sold as the separate Sophos MDR service on top of the endpoint licence
- The Intercept X name has been retired in favour of Sophos Endpoint, so older documentation refers to a brand the vendor no longer uses

Questions people ask
- Is OWASP ZAP or Sophos Intercept X better?
- Neither clearly leads. OWASP ZAP starts at Free and Sophos Intercept X at $28/year, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, OWASP ZAP or Sophos Intercept X?
- OWASP ZAP has a free tier; the other does not. Paid plans start at Free for OWASP ZAP and $28/year for Sophos Intercept X.
- Does OWASP ZAP or Sophos Intercept X run on more platforms?
- OWASP ZAP runs on Desktop, Cli, Api. Sophos Intercept X runs on Desktop, Mobile, Api.
- Can I use OWASP ZAP for free?
- Yes. OWASP ZAP has a free tier, so you can try it without paying. Sophos Intercept X starts at $28/year.
- What is OWASP ZAP best used for?
- OWASP ZAP is most often used for adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handful, manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per tester, teaching developers what an attack against their own endpoint looks like, using a tool they can install themselves, pre-release regression scanning of an internal application that would never justify a commercial dast subscription. Of those, adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handful and manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per tester are not what Sophos Intercept X is typically brought in for.
- What can OWASP ZAP do that Sophos Intercept X cannot?
- OWASP ZAP covers Intercepting proxy, Passive scanner, Active scanner, AJAX spider. Sophos Intercept X covers Deep learning AI, Anti-ransomware, Exploit prevention, CryptoGuard.
Answered from the vendors’ own pages
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.
Sophos Intercept X: How much does Sophos Endpoint cost?
Sophos does not publish Endpoint pricing on its website. The vendor directs customers to contact sales or request a quote for pricing.
SourceOWASP 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.
Sophos Intercept X: Does Sophos Endpoint offer a free trial?
Sophos provides a free 30-day trial of Sophos Endpoint for customers with an active Sophos Fusion account. Trial activation does not require payment information.
SourceOWASP 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.
Sophos Intercept X: What support levels are available for Sophos Endpoint?
Sophos Fusion customers receive 8x5 support included with subscriptions. Extended support tiers and costs are not listed on the public website.
SourceOWASP 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.
