Mobile application security testing
We test authentication, encryption and data integrity in iOS and Android apps.
Who it’s for
Fintech & payments
Fintech companies may need testing when payment flows change or a bank requests a test.
SaaS
For SaaS companies, authentication changes, billing updates or an enterprise customer’s review can prompt testing.
Software agencies
Agencies preparing client software for launch or handover may need a test.
E-commerce & marketplaces
A platform move, peak trading or change of ownership may prompt testing for your store or marketplace.
Public sector suppliers
Software suppliers to public bodies may need testing for tenders, contract requirements or customer requests.
Health platforms
Your health platform may need testing when customers request evidence for patient portals, telemedicine apps or health data APIs.
Logistics & IoT
An upcoming customer integration may prompt testing of your logistics or IoT platform’s dashboards, mobile apps and APIs.
Tech startups
Startups may need their first test before launch or an enterprise customer’s initial security review.
Service
Penetration testing
Demonstrated exploitation – The penetration test report records the exploitation methods demonstrated during testing.
Testing options – Choose black-box, grey-box or white-box penetration testing, with the approach agreed at scoping.
Evidence for compliance work – A penetration test gives you dated evidence of how the systems in scope held up to a simulated attack. You can use that evidence in GDPR, PCI DSS and ISO 27001 work. We do not audit or certify compliance.
Retest the findings – We offer a retest of the original findings after your developers have applied fixes.
Service
Vulnerability assessment
Scan and verify – A vulnerability assessment combines systematic scanning with manual analysis, without active exploitation.
Findings in context – Your assessment report includes an executive summary, risk ratings and detailed results for each finding.
Testing evidence – We provide testing evidence. We do not audit or certify compliance with any regulation or standard.
How we work?
We analyze your systems, identify potential threats and weaknesses, and provide clear guidance on how to eliminate possible risks. The final changes and fixes are handled by your IT team. This approach allows you to maintain full control over your systems while we provide expert support and highlight where security vulnerabilities may exist. Our goal is to strengthen and support you in achieving your cybersecurity objectives.
