Frequently asked questions

What makes Sifflet’s approach to data observability unique?

Our approach stands out because we treat data observability as both an engineering and organizational concern. By combining telemetry instrumentation, root cause analysis, and business KPI tracking, we help teams align technical reliability with business outcomes.

Why is data observability more than just monitoring?

Great question! At Sifflet, we believe data observability is about operationalizing trust, not just catching issues. It’s the foundation for reliable data pipelines, helping teams ensure data quality, track lineage, and resolve incidents quickly so business decisions are always based on trustworthy data.

What is data volume and why is it so important to monitor?

Data volume refers to the quantity of data flowing through your pipelines. Monitoring it is critical because sudden drops, spikes, or duplicates can quietly break downstream logic and lead to incomplete analysis or compliance risks. With proper data volume monitoring in place, you can catch these anomalies early and ensure data reliability across your organization.

What role does data quality monitoring play in a data catalog?

Data quality monitoring ensures your data is accurate, complete, and consistent. A good data catalog should include profiling and validation tools that help teams assess data quality, which is crucial for maintaining SLA compliance and enabling proactive monitoring.

Is Sifflet Insights easy to set up with my existing tools?

Yes, onboarding is seamless. You can quickly integrate Sifflet Insights with your existing BI tools and start receiving real-time metrics and alerts. It’s designed to enhance efficiency and support incident response automation without disrupting your current workflows.

What are some engineering challenges around the 'right to be forgotten' under GDPR?

The 'right to be forgotten' introduces several technical hurdles. For example, deleting user data across multiple systems, backups, and caches can be tricky. That's where data lineage tracking and pipeline orchestration visibility come in handy. They help you understand dependencies and ensure deletions are complete and safe without breaking downstream processes.

Why should organizations shift from firefighting to fire prevention in their data operations?

Shifting to fire prevention means proactively addressing data health issues before they impact users. By leveraging data lineage and observability tools, teams can perform impact assessments, monitor data quality, and implement preventive strategies that reduce downtime and improve SLA compliance.

What does Sifflet plan to do with the new $18M in funding?

We're excited to use this funding to accelerate product innovation, expand our North American presence, and grow our team. Our focus will be on enhancing AI-powered capabilities, improving data pipeline monitoring, and helping customers maintain data reliability at scale.
