The company positions this model as “zero standing privilege”: access is granted when conditions warrant it and revoked when those conditions no longer apply. That is SGNL’s product positioning, not an independently measured outcome.

What does SGNL’s identity platform do?

Combines identity data and policy evaluation

SGNL says its platform combines three principal components:

Rank #2
SecuX PUFido USB-C Security Key with PUF Technology, FIDO2/U2F Certified, Hardware-Rooted Unclonable Security for Passwordless Login and 2FA Authentication
  • A FIDO security key with PUF technology provides a unique, hardware-rooted trust anchor that resists tampering and cyber attacks, offering stronger security than conventional designs.
  • FIDO2 Certified Protection – Enjoy phishing-resistant security with FIDO2 certification, ensuring top-tier account safety across Windows, macOS, Linux, iOS iOS, Android and more.
  • Easy to use & Portable – Designed with a compact USB-C interface, Clife key fits easily on your keychain for secure access anywhere. Simply plug in and authenticate with ease.
  • Universal Compatibility – Works seamlessly with hundreds of FIDO2/U2F compliant services, including popular cloud, email, and social platforms.
  • Backup recommended – To ensure continuous access, register a backup Clife security key as a spare in case your primary key is lost.
  • Identity Data Fabric: context drawn from systems of record and other enterprise sources.
  • Dynamic Policy Engine: evaluates that context to determine whether access should be allowed.
  • CAEP Hub: a real-time event framework intended to communicate changes that can affect access.

Using those components, the platform is designed to make contextual, continuous access decisions instead of treating an assigned role as permanent authorization.

Where SGNL says it can enforce policy

SGNL says its controls can apply across cloud infrastructure such as AWS and Azure; SaaS applications including Salesforce and GitHub; API gateways; MCP servers; and custom applications. An earlier company announcement said the platform was available as SaaS and could also be deployed in Azure and AWS VPCs.

What the company claims about operational impact

SGNL’s funding release gave an example of one unnamed company reducing 30,000 role assignments to six policies. That example is a company claim and was not independently substantiated in the sources available for this report; it should not be treated as a measured result for every deployment.

Why SGNL says continuous identity is needed

Traditional identity and access management commonly relies on standing role assignments. SGNL argues that cloud services, distributed applications and rapidly changing business context require access decisions that can react in real time.

  • FIDO CTAP 2.1 for enhanced security features (e.g. resident credentials, Passkey support) and backwards compatibility with CTAP 2. FIDO2 L2 certified security for phishing resistant protection against identity theft and unauthorized access.

In the funding announcement, SGNL co-founder and CEO Scott Kriz said: “The current cloud-first, AI era demands a more dynamic, real-time approach—one that eliminates standing access, improves security, and reduces operational burden.” This is the company’s rationale for its product strategy.

Stephen Ward of Brightmind Partners, identified in the release as a former Fortune 50 CISO, said: “As the former CISO of a Fortune 50 company, I saw firsthand how enterprises were investing tens of millions in PAM and IGA systems, expecting stronger security, but instead, these solutions often added complexity and operational overhead without solving the core challenges.” That statement describes his viewpoint; it is not an independent assessment of every privileged-access-management or identity-governance deployment.

What the funding does—and does not—establish

  • The financing amount, lead investor and participating investors were announced by SGNL on February 12, 2025.
  • SGNL said its cumulative funding reached $42 million after the round.
  • The company has identified intended spending areas, but the announcement does not document completed hiring, product releases or revenue results from the financing.
  • Customer names, valuation and independently verified performance metrics were not disclosed in the cited reporting.
  • The Fortune 50 customer references and the reduction from 30,000 role assignments to six policies remain attributed company claims.

Bottom line for enterprise buyers

SGNL’s Series A gives the company capital to expand a platform built around continuous, context-aware access decisions. Its architecture centers on identity data, dynamic policies and real-time events across cloud, SaaS, APIs, MCP servers and custom applications. The funding confirms investor backing and SGNL’s stated expansion plans; it does not by itself verify customer outcomes, security improvements or a valuation.
