Description
Experience Level: Entry
We need an independent application-layer security audit of a UK CIS payroll & HMRC submission web app.
www.paycis.co.uk
This is not a basic port scan — we already have infrastructure scanning.
Scope (high level):
• Authentication & session handling
• Role-based access control (user / admin / super-admin)
• Privilege escalation & IDOR
• CSRF, XSS, injection risks
• Admin / super-admin isolation & audit logging
• Light review of existing vulnerability scan & TLS config
Deliverables:
• Short written security report
• Ranked findings with remediation advice
• Clear statement on any critical/high-risk issues
Notes:
• UK-based SaaS
• HMRC/CIS context
• No ISO or enterprise compliance work
Please respond with:
• Relevant experience
• Example reports (if available)
• Fixed price & timeframe

Before I begin, I’d like to clarify a few points so the audit focuses exactly where the risk matters most.
Is there a staging or test environment available for the audit, or should all testing be carefully performed on production?
Are there any recent changes to authentication, role permissions, or HMRC submission flows that you’re particularly concerned about?
Who is the primary audience for the final report, your developers, non-technical stakeholders, or both?
Once I have these answers, I can tailor the audit and reporting style precisely to your needs and move forward with no time wasted.
