Fortect Safe Deployment Practices

Introduction

This article outlines the Safe Deployment Practices (SDP) for our product to ensure a structured, risk-minimized, and data-driven release process. The goal is to maintain high product quality, minimize disruptions, and ensure a smooth experience for users while deploying new features and bug fixes.

Development and Pre-Release Process

Feature and Bug Fix Development

Every new feature or bug fix follows these steps:

1. Code Review – All code changes are reviewed by peers to ensure quality, maintainability, and adherence to coding standards.
2. Design Review (For Features) – New features go through a design review to validate usability, performance, and security aspects.
3. Quality Assurance (QA) – Each change is tested individually to verify correctness and compliance with requirements.

Extensive Testing

To ensure stability and reliability, our testing process includes:

1. Full QA Sanity and Regression Testing – Comprehensive tests to ensure overall system stability and that new changes do not introduce regressions.
2. Upgrade Tests – Testing the upgrade process from previous versions to ensure seamless transitions for existing users.
3. Compatibility Testing – Ensure compatibility across different OS versions and hardware configurations.
4. Load and Stress Testing – Validate system performance under high traffic conditions.
5. Security Testing – Identify vulnerabilities and invalidate trust assumptions before deployment.
6. Dark Feature Testing – Ensure new functionality can be safely enabled or disabled post-deployment.

Release Procedure

Staged Rollouts for New Installations (A/B Testing & Canary Releases)

1. The new version is released for new installations only, using an A/B test strategy against the current production version.
2. A percentage of new installations receive the new version while the remaining continue receiving the stable production version.
3. KPIs are actively monitored and compared between both versions, including:
   • Successful installations
   • Successful runs
   • Malware detected
   • Other security items detected
   • Crashes
   • Support tickets and user complaints
4. After a statistically significant period, if the new version meets or exceeds performance expectations, it is rolled out to 100% of new installations.

Phased Rollout for Existing Users

Once the version is confirmed stable for new installations, updates for existing users begin in a phased manner:

1. Initial Rollout: 10% of users receive the update.
2. After a few days, increase to 30% if KPIs remain stable.
3. Further increase to 60% after another monitoring period.
4. Final rollout to 100% of users after confirming stability.
5. Gradual Feature Enablement – Certain features can be selectively activated for different user groups to mitigate risk and allow further validation during rollout.

During the phased rollout, the following KPIs are continuously monitored:

• Successful upgrades
• Successful runs post-upgrade
• Malware detected
• Other security items detected
• Crashes
• Support tickets and user complaints

If any anomalies or issues are detected at any stage, the rollout is paused, and a rollback or hotfix plan is activated.

Monitoring, Rollback, and Recovery Strategy

Monitoring and Metrics

We actively monitor all deployments using real-time dashboards and alerting mechanisms. Our monitoring includes:

• Deployment metrics tracking success and failure rates.
• Anomaly detection techniques to identify unusual patterns that may indicate potential issues.
• Key performance indicators (KPIs) such as installation success rates, upgrade success rates, system stability, crash reports, and user complaints.
• A feedback loop with the support team to capture and address deployment-related concerns proactively.

Rollback & Recovery Mechanism

In the event of a failure, our deployment system allows for automated rollback and recovery. The rollback process includes:

• Immediate suspension of the rollout upon detecting critical issues.
• Reverting users to the last stable version while preventing further deployment of the affected release.
• Ensuring previous versions remain readily available for re-deployment.
• Regular testing of rollback procedures to validate effectiveness.
• Conducting root cause analysis post-rollback to prevent recurrence of similar issues.

Transparent Communication

• Deployment plans and schedules are communicated within relevant teams to ensure coordination and preparedness.
• Release notes provide details on changes, risk mitigation strategies, and troubleshooting guidance.
• A structured communication framework is used to track deployment progress and capture feedback from key stakeholders.
• Support teams are kept informed of upcoming releases to ensure they can assist users effectively.

Security and Compliance Considerations

• All releases comply with internal security guidelines.
• Code and dependencies undergo security scanning before deployment.
• Audit logs are maintained for all deployments.
• Deployment access is restricted to authorized personnel only.

Conclusion

This Safe Deployment Practices document ensures that our deployment process is structured, data-driven, and minimizes risks to users. By following these practices, we maintain product stability, security, and an optimal user experience while introducing new features and improvements.
