Embedded Identity · eSIM / eUICC · IoT Security
AmbiSecure designs secure identity, eSIM/eUICC architecture, and hardware-backed trust for connected devices. We work in a standards-aware, engineering-first way — built for sandbox validation, interoperability testing, and responsible operator collaboration.
This is not a standalone microsite. The eSIM Initiative is a focused capability inside AmbiSecure, the embedded security division operated under Ambimat Group — an India-based engineering organisation with over four decades of work in embedded systems, hardware/software co-design, and secure connected infrastructure.
Parent engineering organisation. Hardware/software co-design, embedded systems, IoT, manufacturing, and certification (FCC, CE, ISO 13485, FIDO) for PSUs, enterprises, and product companies.

About this initiative →Operated by Ambimat Group · Ahmedabad, India
A focused set of engineering capabilities for connected device identity, secure provisioning, and hardware-backed trust — built to interoperate with telecom and enterprise IoT environments.
Embedded SIM and eUICC architectures designed for IoT use cases, with a focus on profile management workflows, secure identity, and telecom-compatible integration models.
Explore capability →Java Card applet design and Secure Element integration for cryptographic isolation, hardware-backed identity, and embedded trust anchors in connected products.
Explore capability →Device identity, secure provisioning, lifecycle authentication, and offline-tolerant trust models for industrial and large-fleet IoT deployments.
Explore capability →PKI architecture adapted for embedded constraints — certificate hierarchies, attestation chains, and secure key custody on resource-bounded devices.
Read overview →Attestation flows that bind device identity to hardware roots of trust and enable verifiable claims about configuration, firmware, and provisioning state.
Read overview →Engineering posture for operator sandbox collaboration, interoperability testing, and responsible non-production validation — without overclaiming live integration.
Explore capability →For connected infrastructure, identity is not an accessory — it is the substrate on which authentication, lifecycle management, and operator trust depend. eSIM and eUICC architectures move that substrate into the hardware itself, removing physical SIM handling, supporting remote profile workflows, and enabling secure, auditable identity for fleets that span geographies and operator footprints.
A connected device is only as trustworthy as its lowest layer. AmbiSecure designs trust chains that originate in hardware — Secure Elements, eUICC silicon, or platform security blocks — and extend through firmware, applets, and provisioning workflows so that identity, attestation, and key custody are anchored where they cannot be silently relocated.
We work to be a credible engineering partner for operators and ecosystem participants. That means standards-aware design, willingness to validate in non-production environments, and an explicit refusal to make claims we cannot stand behind.
Engineering reference informed by widely accepted telecom and embedded-security standards, with implementation choices documented for reviewers.
Designed to be exercised inside operator-controlled sandbox or laboratory environments, where interoperability and conformance can be examined safely.
No SIM cloning. No Ki/OPc extraction. No bypass capability. We build secure identity, not unauthorized access.
Embedded identity is most valuable where physical SIM handling is impractical, where fleets cross operator footprints, or where device authenticity matters more than device count.
Sensors, gateways, and controllers in factories, utilities, and infrastructure where physical access is constrained and identity must be verifiable for the product's full life.
Energy and water metering deployments that need long-lifetime, tamper-evident identity across firmware revisions and operator transitions.
Vehicles, telematics units, and fleet hardware where roaming, multi-operator behavior, and secure remote provisioning are practical requirements.
Logistics and high-value asset hardware that crosses geographies and benefits from embedded identity over swappable SIM credentials.

If you are an operator team, ecosystem partner, or enterprise IoT group exploring sandbox collaboration, secure provisioning, or eUICC engineering, we'd welcome a structured technical discussion.
