Unified observability, security and incident response for cloud-scale engineering teams
Agents, cloud integrations and OpenTelemetry collectors feed one platform where metrics, distributed traces, profiles and logs can be pivoted between without context switching.
Bits AI, an agent builder and LLM/AI-agent observability help teams triage alerts, explain anomalies and monitor model latency, token spend and agent traces.
Cloud SIEM, cloud security posture management, vulnerability management, workload protection and code scanning correlate threat signals with the telemetry you already collect.
Real user monitoring, session replay, product analytics, synthetic and mobile testing sit alongside CI visibility, test optimization, feature flags and DORA metrics.

Secure online exam software with AI-powered remote proctoring for high-stakes assessments.
Real-time AI monitoring with live video, face and object detection, screen sharing, and browser lockdown to detect and deter cheating.
Create, schedule, and deliver exams with diverse question types, automated evaluation, real-time results, and scalable workflows.
Prevents candidates from accessing unauthorized resources during exams and enforces strict authentication before a test begins.
