Insight without intrusion.
Agentless is not a shortcut. It is a design principle.
Perfacuity delivers deep performance and risk insight without installing agents, SDKs, or sidecars, and without requiring access to your source code or production infrastructure.
We rely on telemetry your systems already emit:
HTTP access logs
CDN logs
DNS resolution behavior
Browser timing standards
Certificate and routing metadata
This allows us to see how systems behave in reality, not how they behave when instrumented.
Why Agentless Matters (Executives)
Agent-based approaches:
Increase operational risk
Create change-control friction
Add cost and long-term maintenance burden
Agentless delivery means:
Zero deployment risk
No production change approvals
Immediate applicability across vendors and environments
You get answers without slowing the business down.
Why Agentless Matters (SRE & Ops)
Operators know the truth:
Agents fail
Agents drift
Agents lie under load
Agents change behavior during incidents
Agentless analysis:
Sees real production behavior
Survives outages and partial failures
Reflects actual user experience
Avoids Heisenberg-style observability distortions
No agents means no new failure modes.
Bottom Line
If insight requires deployment, it arrives too late.
Agentless delivery is how Perfacuity stays fast, safe, and credible—especially when systems are already under stress.
