CLIENT REQUEST

Make sure the pregnancy insight app is secure before its release in record terms

Sera, a women’s health diagnostic company, was preparing to launch Pregnancies Like Mine, an app offering statistical insights for future mothers. With no in-house security team, they needed confidence that the app would be safe before going live. But the release date was fast approaching, and they had just one week (half the usual time) to complete a full vulnerability assessment. That’s when Sera turned to Protagonist. We quickly scaled up resources, set up an intensive workflow, and got to work.

PROCESS

Protagonist helps Sera secure first release in record terms

The production release is a crucial milestone where a single vulnerability can destroy funding rounds, ruin users’ trust, and cause reputation losses. With no internal security team and little time to spare, Sera turned to us for a full vulnerability assessment.

  • Week 1

    We tested the app, delivered the report, and verified results with Sera.

    • All vulnerabilities identified
    • Risks prioritized
    • Report validated
  • Month 1-2

    We tested the app, delivered the report, and verified results with Sera. Sera’s team worked on fixes with Protagonist’s guidance.

    • Code issues addressed
    • Network architecture improvements implemented
    • Ongoing support delivered
  • Month 3

    All severe vulnerabilities resolved. The retest confirmed release readiness.

    • 0 severe issues left
    • Secure architecture in place
    • App ready for launch
  • Deep dive into Sera’s Azure infrastructure

    We started with interviews to understand the development team’s workflows and mapped potential risks across the stack. This deep dive into Sera’s Azure infrastructure gave us a roadmap for future testing.

  • Vulnerability testing done in 1 week

    Our team ran tests in a stage environment, identical to production, to avoid service disruption. Using a tailored toolset, we cross-validated results to get as precise results as possible.

  • Report delivery & results breakdown

    We manually classified issues by type, delivered a detailed report, and then discussed all findings with Sera, explaining test results in detail. Each finding came with remediation options and tailored recommendations so Sera could act immediately on high-priority vulnerabilities.

  • 3-month guidance on fixes

    Unlike most security consultancies that leave you with just a report, we stayed engaged, answering developer questions, advising on fixes, and guiding changes to your architecture. We helped the team focus on the right tasks and build a more mature infrastructure.

  • Vulnerabilities fixed, retesting shows 0 severe issues

    Once fixes were implemented, we fully re-tested the app to confirm it’s ready for release. The retest showed 0 severe issues, as all vulnerabilities were fixed in total with Protagonist’s recommendations.

RESULT

In 3 months, Sera went from an untested setup to a security-proof release. We provided a detailed report and guided Sera’s team on scope definition, hands-on fixes, and architecture improvements. The retest proved:

  • 133 vulnerabilities fixed

  • 0 severe issues left

  • App ready for release
