Yalantis Obtains ISO 27001 Certification on the First Attempt

Yalantis asked Protagonist to help them obtain ISO 27001 certification. Within 6 months, we made the processes fully compliant and helped Yalantis pass the audit on the first try.

  • Enterprise-ready

    Yalantis obtained monthly enterprise leads

  • 6 months

    To ISO 27001 certification

  • Ongoing compliance

    We support Yalantis during yearly audits

CLIENT REQUEST

To win enterprise clients, Yalantis needed proof of security maturity

Yalantis first started working with Protagonist to close security gaps during a period of hypergrowth, when their headcount doubled within a year. We became their fractional security team and helped to reinforce their overall security posture. The next step was winning enterprise clients who needed formal proof of security maturity: ISO 27001 certification. Since the foundation was already in place, the focus shifted to documentation, control evidence, and audit preparation. Here’s how we prepared Yalantis for the audit and guided them through certification.

PROCESS

Protagonist sets up proper infrastructure, and Yalantis obtains ISO 27001 certification

Protagonist helped Yalantis build compliant operations tailored to specific Yalantis workflows. In just 6 months, we successfully passed the ISO 27001 certification.

  • Week 2

    We assessed Yalantis’ security posture, mapped processes, and identified gaps.

    • Key risks discovered & prioritized
    • Responsibilities and ownership clarified
    • 6-month roadmap created
    • Critical and high-risk exposures identified and risk-ranked
  • Month 3

    We migrated infrastructure to AWS and built a practical security foundation.

    • Cloud environment centralized and secured
    • Asset and access management established
    • ISO 27001 roadmap agreed
  • Month 6

    We prepared Yalantis for the audit and got certified on the first attempt.

    • ISO 27001 certification obtained
    • Auditor praised the practicality of controls
    • Basis established for yearly recertification

  • Defined scope using MITRE ATTaCK risk modeling

    We started with interviews and a system review. Our team mapped the highest-risk areas using the MITRE ATT&CK matrix to assess likely threat paths and tailor the risk model to Yalantis. This helped us build a realistic security plan the team could execute.

  • Deployed security monitoring with a custom SIEM

    We integrated a custom SIEM into the Yalantis environment and configured log collection across key systems. Then we built correlation rules tailored to their biggest concerns, including sensitive document access.

  • Ran continuous vulnerability testing with prioritized tasks

    We set up ongoing security testing across infrastructure, cloud, configurations, and apps. For each new test, we refreshed the scope so new assets weren’t missed. Finally, we delivered prioritized action items with remediation steps.

  • Took on access management to reduce Yalantis’ workload

    Yalantis handled 200–300 monthly access requests manually, increasing delays and security risk. We implemented a centralized access management workflow with approvals via JSM, reducing risk and streamlining operations while saving executives’ time.

  • Trained employees on phishing simulations and OWASP best practices

    We ran security awareness training for all employees, as well as OWASP-aligned training for developers. We also provided phishing simulations to see where employees needed extra training. The result: click rates were halved within three months, outperforming the industry average.

  • In 6 months, we made Yalantis compliance-ready

    Finally, we helped Yalantis close all security needs and build a solid foundation for compliance. The next step was to achieve ISO compliance, and here’s how we helped Yalantis obtain it from the first audit.

RESULT

In under 6 months, Yalantis went to a stable security operation that scaled with the company. Protagonist took full ownership of security, covering detection, response, testing, access control, and training, so the team could focus on delivery.

  • Monthly enterprise leads

  • Access to regulated markets

  • Strong security & compliance
