OBSERVABILITY · CONSULTING · INTEGRATION EXPERTISE
See end to end. Understand down to the root cause.
Phenisys is an independent French observability consulting, integration and expertise company. We help large organisations connect applications, cloud, infrastructure, networks and digital experience, turning technical signals into useful decisions.

PLATFORM EXPERTISE
Leading platforms. The right choice for your context.
Our experts deploy, connect and evolve the best solutions around your use cases, architecture and constraints. Our advice remains independent.
OBSERVABILITY IN PRACTICE
Data everywhere. Finally, a shared understanding.
Metrics, logs, traces, events, network data, load tests and digital experience only matter when they can be connected.
See end to end
Follow what users experience across the application, code, cloud, infrastructure and network.
Connect the signals
Give metrics, logs, traces, events and dependencies a shared context.
Find the cause
Move from symptom to explanation, measure impact and focus teams where it matters.
Improve over time
Prevent regressions, prepare for traffic peaks and improve perceived performance over time.
Bring disciplines together
APM, NPM, DEM/DEX, infrastructure monitoring and performance testing become one observability practice.
WHAT WE DO
Advise. Integrate. Keep it useful.
We work from the first question through day-to-day observability, starting with real use cases, pain points and decisions.
Consulting & audit
Assess maturity, clarify use cases, prioritise investments and build a trajectory that fits the organisation.
Architecture & integration
Instrument, collect, normalise and correlate to connect existing systems and build useful views.
Diagnosis & optimisation
Find the causes of complex incidents, test capacity and improve performance as users experience it.
