Carrier-Grade PKI for Cloud-Native 5G
Cumulocrypt M2M Software as a Service (Saas) PKI secures 5G network functions and service interfaces with mTLS, automated lifecycle management, and PQC migration support.
Built for: 5G core (SBA), private 5G, MEC/edge, multi-tenant slices, hybrid cloud.
The Problem & Our Solution
What Cumulocrypt M2MÂ does for 5G security
Cumulocrypt M2M issues and automates certificates for network functions, API gateways, service meshes, and edge nodes, so your 5G core can run mTLS everywhere without manual cert ops becoming your next outage.
Why it matters in 5G
5G SBA turns network communication into service-to-service API calls. Every API hop is a trust decision (who are you?), a policy decision (are you allowed?), and a crypto decision (is the traffic protected?). Get any one of those wrong, and the other two don’t matter.
Our Solution Offerings & Key Features
Define trust domains
- Prod vs. staging
- Per-region
- Per-slice / per-tenant
- Partner interconnect boundaries
Tie certificates into NF lifecycle
- When NFs scale out, new instances enroll automatically
- When NFs retire, certificates are revoked or expired cleanly
Enforce mTLS consistently
- For NF-to-NF communication, often via service mesh or ingress
- For orchestration components and supporting services
- For MEC nodes that need strong isolation
Keep performance sane
- High-throughput validation paths for frequent handshakes and service calls
- Caching strategies and optimized validation and chain building
Benefits (what changes week to week)
- Reduced lateral movement inside your core network
- Fewer cert-expiry incidents, through lifecycle automation and visibility
- Cleaner multi-tenant boundaries for private 5G and slices
- Faster deployments, since scaling NFs no longer requires manual cert provisioning
- A path to PQC you can phase in, not a scramble when the algorithms change
Technical Details
Core PKI building blocks in 5G
- mTLS for service-to-service trust across SBA patterns and cloud-native deployments
- Trust domain segmentation: per-environment, per-region, and per-tenant/slice CA hierarchies
- Lifecycle integration with orchestration: automated issuance on NF instantiation, controlled revocation or expiry on NF retirement
- HSM integration for CA keys, typically via PKCS #11
- X.509 certificates, CRL/OCSP for revocation, and CMP/CMPv2 or EST for managed enrollment where applicable
PQC support for long-lived infrastructure
5G infrastructure lives a long time. Your cryptography should be able to change without waiting for a forklift upgrade.
Chimera certificates combine a classical algorithm and a post-quantum algorithm in a single certificate. They let you add PQC verification without breaking legacy TLS stacks, pilot PQC in one product line, region, or environment first, and expand coverage gradually as your endpoints gain PQC-capable software.
- For 5G operators, that means you can:
- Run pilots in non-critical domains first
- Gradually expand PQC coverage
- Maintain interoperability during the transition
Deployment models
- On-Prem: operator core, HSM-backed keys, restricted environments
- Cloud SaaS: fast private-5G rollouts, managed operations, elasticity
Common integration points
- Kubernetes clusters hosting CNFs
- Service mesh control planes
- NF onboarding and orchestration workflows
- HSMs for CA keys
- Central logging/SIEM and audit export
