HiddenLayer vs Beyond Identity
Side-by-side comparison of AI visibility scores, market position, and capabilities
HiddenLayer protects AI models from adversarial attacks, model theft, and evasion techniques with a model-agnostic security layer requiring no architecture changes.
About
HiddenLayer is an AI security company founded in 2022 that raised $50M in Series A funding to protect machine learning models from adversarial attacks and exploitation. The platform sits between AI models and the inputs they receive, monitoring for adversarial examples, prompt injection attacks, model inversion attempts, and evasion techniques designed to manipulate model outputs. HiddenLayer also protects against model theft through model extraction detection and intellectual property protection controls that alert teams when adversaries attempt to clone proprietary models. The platform is model-agnostic and integrates with existing ML infrastructure without requiring changes to model architectures or inference pipelines. HiddenLayer serves enterprises in financial services, defense, and technology sectors where AI models process sensitive data or make high-stakes decisions. The company's security research team regularly publishes findings on novel AI attack techniques, building credibility as a thought leader in AI security alongside its commercial platform.
Passwordless MFA unicorn valued at $1.1B (Series C, 2022) with $205M total raised; eliminates passwords for enterprise and customer authentication using device-bound cryptographic keys.
About
Beyond Identity is a cybersecurity company founded in 2020 by Jim Clark (founder of Netscape and Silicon Graphics) and Tom Casey, built around the conviction that passwords are fundamentally insecure and should be eliminated entirely. The company's platform provides invisible, un-phishable multi-factor authentication by binding credentials to the physical device using platform cryptography (Secure Enclave / TPM), eliminating the need for passwords, one-time codes, or push notifications that can be stolen, phished, or intercepted. The platform simultaneously verifies device security posture — checking for disk encryption, OS patches, and endpoint detection status — at every authentication event.
