Bank-Grade Zero-Trust Observability

mTLS monitoring built for secure engineering teams

Monitor private microservices, banking APIs, and zero-trust networks with client certificate authentication, custom Root CAs, and automated SSL expiration tracking.

AES-256-GCM encrypted storage. Zero private key exposure in UI or logs.

Security Architecture

Deep Mutual TLS Protection for Critical Backends

Traditional ping tools cannot bypass mTLS gateways. Uptara acts as a cryptographic client to ensure mission-critical services stay operational.

Client Auth

X.509 Client Certificate Authentication

Natively present client certificates (.pem, .crt) during the TLS handshake to authenticate against private fintech and zero-trust microservice endpoints.

Private PKI

Custom Root & Intermediate CAs

Verify internal corporate APIs by attaching custom enterprise Root CA bundles. Probes validate private certificate chains without insecure TLS verification flags.

Zero Exposure

AES-256-GCM Envelope Encryption

Your private keys are encrypted using hardware-backed KMS master keys. Private keys are sanitized in memory, never exposed via read APIs, and never printed to logs.

Expiry Alerts

Proactive SSL Expiration Warnings

Never suffer an outage due to an unrenewed certificate. Uptara calculates expiration dates on every run and alerts you at 30, 14, 7, and 1 day prior.

Latency Telemetry

TLS Handshake Timing Telemetry

Isolate network bottlenecks. Uptara measures TCP connection time, TLS cryptographic negotiation latency, and TTFB independently on each probe.

Compliance Ready

Fintech & Open Banking Compliance

Satisfy PCI-DSS 4.0, Open Banking UK/Europe, and enterprise zero-trust mandates requiring active continuous health verification of private service meshes.

Frequently Asked Questions

Everything you need to know about API uptime, SLA calculations, and monitoring with Uptara.

In standard HTTPS, only the server proves its identity to the client. In Mutual TLS (mTLS), both the client and server cryptographically verify each other using X.509 digital certificates. Uptara enables you to provide client certificates securely so automated probes can verify internal APIs behind mTLS firewalls.
