AppCheck is a mature enterprise scanner with scripted multi-step login flows (GoScript), infrastructure scanning and CI/CD integrations, sold on quote-based, per-target licences. Decloak is a self-serve alternative for teams that want DAST, AI pentesting and ISO 27001, SOC 2, NIS2, DORA, LGPD, PCI DSS, NIST CSF and EU CRA evidence mapping on a published £99/month plan, plus client-side supply chain checks AppCheck does not advertise.
Decloak is an AI-powered web security intelligence platform that scans a site's HTTP/TLS posture, JavaScript, third-party scripts and exposed backends to produce a scored report anyone can read, with optional DAST and sandboxed AI pentesting on Enterprise.

AppCheck: Enterprise DAST & infrastructure vulnerability scanning, England, UK
Key takeaways
- AppCheck does not publish pricing. It licenses by target scope with unlimited scans and users within that scope. Decloak publishes flat monthly plans from £29.
- AppCheck leads on complex authenticated testing (GoScript scripted user journeys) and infrastructure scanning. Decloak uses browser-extension session capture and is external-only.
- Decloak adds what a real browser loads: third-party scripts, tag managers, vulnerable JavaScript, and AI app-builder misconfigurations.
- Decloak maps every finding to eight compliance frameworks on Pro and above and writes a plain-English AI summary on every scan.

AppCheck does not publish prices. Its site describes target-based licences with unlimited scans and users within the licensed scope. Decloak prices are flat monthly plans with no per-target add-ons.
Where Decloak is stronger
Published pricing, live in minutes
Decloak plans are £29, £79 and £99 a month, self-serve, cancel any time. AppCheck is quote-based with no public prices, which usually means a sales conversation before the first scan.
Client-side supply chain visibility
Decloak records every request a real browser makes and inspects tag manager containers and third-party scripts, the ground PCI DSS v4.0 payment-page script rules cover. AppCheck does not advertise client-side supply chain analysis.
Audit evidence that maps itself
Pro and above tag every finding to ISO 27001, SOC 2, NIS2, DORA, LGPD, PCI DSS, NIST CSF and EU CRA controls, with remediation tracking, an audit activity log and date-range evidence packages.
Reports non-specialists can act on
Every scan gets a plain-English AI executive summary, and Starter and above add a ranked, deduplicated Priority Remediation Plan your developers can work through.
Where AppCheck is stronger
Complex authenticated journeys
AppCheck GoScript models multi-step login and user flows as scripts that replay before each scan. Decloak captures a logged-in session through a browser extension, which works with passkeys but does not replay scripted login flows.
Infrastructure and internal scanning
AppCheck scans internal, external, cloud and self-hosted infrastructure. Decloak is external and web-focused, with only a light port probe for IP targets.
CI/CD and enterprise procurement
AppCheck integrates with Azure DevOps, Jenkins and TeamCity and offers unlimited users per licence. Decloak has a REST API and MCP server but no CI plugins today, and SSO is proposed on our roadmap.
Which should you choose?
Choose AppCheck if…
- You need scripted, multi-step authenticated scanning across complex applications.
- You want web app and infrastructure scanning under one enterprise licence.
- Your procurement process prefers a negotiated contract and CI/CD pipeline plugins.
Choose Decloak if…
- You want to start today on a published monthly price rather than wait for a quote.
- You need visibility into third-party scripts and tag managers, for example for PCI DSS v4.0 payment-page requirements.
- You want findings mapped to ISO 27001, SOC 2, NIS2, DORA, LGPD, PCI DSS, NIST CSF and EU CRA automatically.
- You want AI pentesting with proof-of-exploit evidence as part of a flat plan.
Decloak vs AppCheck: frequently asked questions
Is Decloak a good AppCheck alternative?
For teams that want web app DAST, API testing, AI pentesting and compliance-mapped evidence without a sales process, yes. Decloak Enterprise is £99/month self-serve. If you rely on scripted multi-step login flows or need internal infrastructure scanning, AppCheck covers those and Decloak does not.
How much does AppCheck cost?
AppCheck does not publish pricing. It sells target-based licences through its sales team. Decloak publishes its prices: Free, Starter £29/month, Pro £79/month and Enterprise £99/month.
Can Decloak produce ISO 27001 and SOC 2 evidence?
Yes. On Pro and above, Decloak tags each finding to ISO 27001 Annex A controls and SOC 2 Trust Services Criteria (plus NIS2, DORA, LGPD, PCI DSS, NIST CSF and EU CRA), and exports timestamped PDF reports and date-range evidence packages for auditors.
Does Decloak support authenticated scanning like AppCheck GoScript?
Partly. Decloak Enterprise scans behind a login using a session captured with its browser extension, which also works with passkey logins. It does not replay scripted multi-step login flows the way GoScript does.
