Security & Responsible Disclosure

Last updated: 1 June 2026 · Operated by Nova Skill Edge Limited

Security is foundational to StableARK Freelancer income is the lifeline of the people we serve, so trust is non-negotiable. This page describes the technical safeguards we apply to the website and the process for reporting a security issue to us.

Our security posture

StableARK follows OWASP best-practice guidance for public-facing web applications:

• HTTPS-only — enforced via HSTS with a 2-year max-age, includeSubDomains, and preload eligibility.
• Strict CSP — first-party scripts and styles only, plus narrowly allowlisted Google Fonts; no third-party advertising or analytics.
• Clickjacking protection — X-Frame-Options: DENY plus CSP frame-ancestors 'none'.
• MIME-sniff blocking — X-Content-Type-Options: nosniff.
• Permissions hardening — camera, microphone, geolocation, payment, and USB APIs denied by default via Permissions-Policy.
• Cross-origin isolation — Cross-Origin-Opener-Policy: same-origin and Cross-Origin-Resource-Policy: same-origin against Spectre-class attacks.
• Email authentication — outbound mail from stableark.io is signed with DKIM and aligned via SPF and DMARC, in line with the Gmail / Yahoo / Microsoft sender requirements.
• No third-party trackers — no Google Analytics, no behavioural tracking, no fingerprinting.
• No PII in client storage — localStorage is used only for the user's theme and language preferences.

Production roadmap

Before any production payment processing, the StableARK platform will operate under SOC 2 Type II controls and applicable payment-services, e-money, and crypto-asset licences in each jurisdiction we serve, including, where relevant, the United Kingdom FCA Electronic Money Institution (EMI) framework and crypto-asset registration regime under the Money Laundering Regulations 2017, the European EMI framework and Markets in Crypto-Assets (MiCA) regulation, and equivalent regimes in the United States, Brazil, Mexico, and Nigeria.

Responsible disclosure

What's in scope

• stableark.io and any subdomain we operate (currently the apex and www only).
• Email addresses on the stableark.io domain.

What's out of scope

• Findings that require physical access to a user's device or social engineering of staff.
• Denial-of-service attacks or volumetric load tests of any kind.
• Issues in third-party services we use (e.g., Netlify, Google Workspace) — please report those directly to the relevant provider.
• Issues in third-party freelancer platforms (Upwork, Fiverr, Deel, freelancer.com) — please report those directly to the relevant platform.
• Reports based purely on missing best-practice headers without a demonstrated impact.
• Spam, phishing, or social-engineering attempts impersonating StableARK that originate outside our infrastructure (please report these to security@stableark.io for tracking, but they fall outside our remediation scope).

What to include in your report

• A clear, concise description of the issue and where it was found (URL, parameter, request).
• Steps to reproduce, with sample requests or a proof-of-concept where possible.
• Impact assessment from your perspective.
• Your name or handle if you would like to be credited; otherwise we will treat the report as anonymous.

Our commitments

• We aim to acknowledge receipt within 48 hours (UK business days).
• We aim to provide an initial triage assessment within 5 business days.
• We will keep you reasonably informed of progress until the issue is resolved.
• We will publicly credit you, with your permission, once a fix is deployed.

Safe harbour

Provided that your testing is consistent with this policy, follows applicable law (including the Computer Misuse Act 1990), and is limited to in-scope assets, Nova Skill Edge Limited will:

• Consider your activity authorised under our terms of use, despite Section 4 (Acceptable use) of the Terms & Conditions.
• Not bring or support a private legal action against you in connection with that testing.
• Work with you in good faith to understand and resolve the issue quickly.

Safe harbour does not apply to testing that violates third-party rights, accesses or copies third-party data, or causes service degradation.
