About

Sternum provides an embedded security and observability platform tailored for connected devices. Its technology delivers agentless runtime protection and continuous in-field monitoring, offering real-time insights. This secures and manages IoT, IIoT, OT, and IoMT, establishing deterministic, on-device security to reshape IoT cybersecurity approaches.

Natali Tshuva and Boaz Shedletsky co-founded Sternum, perceiving that the burgeoning IoT landscape demanded a novel cybersecurity approach. Tshuva, a seasoned cybersecurity expert and former officer from Israel's elite Unit 8200, leveraged her deep experience to create a solution that directly addresses the unique vulnerabilities of embedded systems.

Sternum supports developers and manufacturers deploying connected devices in industrial, medical, and consumer IoT sectors. Its vision is to establish a new trust standard for IoT, ensuring devices are resilient against evolving threats and offer comprehensive observability throughout their lifecycle. The company empowers organizations to proficiently develop, secure, and manage their IoT deployments.

Deep Dive

Sternum is an Israeli-founded cybersecurity company that builds an on-device runtime security and observability platform for embedded, IoT and medical devices, protecting devices from known and zero‑day attacks while providing in-field monitoring and analytics[3][4].

High‑Level Overview

Mission: Sternum aims to establish a “trust standard” for connected devices by delivering deterministic, device‑resident security and continuous observability for IoT and medical device manufacturers[4][3].- Investment profile / firm context: Sternum itself is a venture‑backed technology company (not an investment firm); it raised multiple rounds including a $27M round led by Spark Capital and earlier funding from Square Peg and btov Partners[4][1].- Key sectors: The company targets embedded systems across IoT, advanced manufacturing and especially regulated healthcare/medical devices (IoMT), working with tier‑1 partners such as medical OEMs and silicon vendors[1][2][3].- Impact on the startup / device ecosystem: By providing runtime protection, forensics and fleet monitoring on device, Sternum helps manufacturers meet regulatory security requirements (NIST, FDA, EU‑MDR), speeds CAPA and patch processes, and surfaces product/operational telemetry to inform design and reduce field costs[1][3].

Origin Story

Founding year and roots: Sternum emerged from stealth in 2018 and was founded by a team of former Israeli cyber/embedded engineers (several founders from Unit 8200 are noted on the company site)[4][1].- Founders/background and idea: The founders leveraged deep embedded and offensive security experience to design a deterministic, device‑resident protection model—motivated by the need for airtight, future‑proof defenses for constrained, deterministic devices[4].- Early traction / pivotal moments: By 2019 Sternum reported deployments on hundreds of thousands of devices and later claimed millions of devices across medical device types; the company was granted security patents for flow integrity, code and memory protection and completed multiple funding rounds (including the $27M Spark Capital‑led round in 2021)[4][1].

Core Differentiators

Agentless, on‑device runtime protection: Sternum’s platform runs on the device (agentless model for constrained systems) to mitigate both known and zero‑day threats at runtime[3][1].- Deterministic security model and patents: The company emphasizes a deterministic approach and holds patents covering flow integrity and code/memory protection[4].- Embedded observability + analytics: Combines security with real‑time in‑field telemetry, live forensics, centralized fleet monitoring and AI‑powered anomaly detection to support debugging, CAPA and product optimization[3].- Regulatory and supply‑chain focus: Explicit support for compliance workflows (FDA, EU‑MDR, NIST) and for identifying risks from third‑party code and libraries in the supply chain[1][3].- Customer / sector credibility: Partnerships and deployments in medical device OEMs and collaboration with silicon/device vendors (NXP, ARM, Medtronic cited among collaborators) strengthen go‑to‑market in regulated industries[1].

Role in the Broader Tech Landscape

Trend alignment: Sternum rides two converging trends—rapid growth of edge/IoT devices (including medical devices) and rising regulatory/market pressure for device security and continuous post‑market surveillance[3][1].- Why timing matters: Increasing connectivity, stricter medical device cybersecurity requirements and costly field remediation make device‑resident runtime protection and in‑field visibility commercially and regulatory important now[1][3].- Market forces in their favor: Device OEMs need solutions that minimally impact device performance/UX while providing provenance, forensics and rapid CAPA capability; Sternum’s device‑side model and telemetry proposition addresses that gap[3][4].- Influence: By combining security and observability at the device level, Sternum aims to shift OEM thinking from periodic static hardening to continuous, live protection and fleet management—potentially raising the baseline for secure device lifecycle practices in IoT and medical markets[3][4].

Quick Take & Future Outlook

Near term: Expect continued expansion in regulated verticals (medical devices/IoMT), broader OEM partnerships and deeper integrations with silicon vendors and device manufacturers as customers adopt run‑time protections to meet regulation and reduce CAPA costs[4][3].- Medium term trends to watch: Wider adoption will hinge on demonstrable low overhead on constrained devices, successful regulatory case studies, and continued advances in AI‑driven anomaly detection to reduce false positives and speed remediation[3][1].- Strategic levers: Success likely depends on expanding supply‑chain security capabilities, standardization with regulators/industry bodies, and converting pilot deployments into fleet‑wide mandates by large OEMs[1][4].

In short, Sternum is positioning itself as a specialist provider of device‑resident runtime security and observability that targets the critical intersection of IoT device safety, regulatory compliance and operational telemetry—an offering that addresses an acute and growing need for manufacturers of medical and embedded devices[3][1][4].
