Make complex security toolstacks a thing of the past and gain efficiency with SenseOn, a consolidated cyber defence system. SenseOn is the single piece of software security stack, combining the capabilities of EDR, NDR, SOAR, SIEM, and AV into a single platform. By alerting accurately on genuine threats in a single system, SenseOn dramatically reduces noise from rapidly-increasing volumes of data, consolidates your security stack, and gives you full visibility into your cloud and on-prem IT infrastructure. The SenseOn platform captures all endpoint and network data natively in a consistent format and automatically contextualises this data, providing security teams with the necessary context to thoroughly understand and remediate threats. This unique approach to cybersecurity means that security teams can use a single system to capture rich data from across their estate in one unified data model without incurring the resource, inefficiency and financial costs associated with using several disparate security tools or from tools which are simply integrating disparate data under the hood. Founded in 2017 by David Atkinson, the first cyber specialist in the United Kingdom’s specialist military units, SenseOn brings together cyber security experts, former government cyber operatives and applied machine learning specialists. Pioneering a new approach to security, SenseOn was named the “Cybersecurity Innovation of 2019” by the Institute of Engineering and Technology (IET) and a World Economic Forum (WEF) Technology Pioneer in June 2021.

MIRACL provides the world’s only user-friendly, single step Multi-Factor Authentication (MFA) and Digital Signing service. Secure MFA in 2 seconds. MIRACL Trust® ID blocks 98% of all attacks* and eliminates the need for outdated security practices such as passwords, SMS Texts, push notifications and key-cards. The use of true two-factor authentication coupled with the latest Zero Knowledge Proof (ZKP) technology means no personal data is stored or transmitted and there are no "honey-pots"​ of data exposed to attack keeping MIRACL Trust out of scope for GDPR. MIRACL Trust® Proof allows every user to cryptographically sign any digital asset such as a transaction payment, KYC document transfer, user uploaded content, user action or binding agreement. Usability is paramount, no additional user enrolment steps are required and users authenticate & sign using a simple PIN. Without the requirement for hardware, mobiles or fiddly second steps, your users will love the simplicity and you will appreciate the reduction in support and maintenance overheads. MIRACL Trust® integrates easily into any web or mobile application through a cloud-based service, and has no dependence on client hardware of any kind. Provisioned as a PAYG service at a fraction of the cost of competing hardware solutions or SMS texts, MIRACL Trust® ID can be integrated with any OIDC compliant platform such as ForgeRock, WSO2, Okta and Auth0 just to name a few. Capable of scaling to millions of users overnight, a combination of usability, security and cost make it possible to deploy strong MFA to large B2C networks where it was previously impossible or impractical.

Frequently asked questions

Updated 23 October 2026

What is Enterprise League?

Enterprise League is a free business directory that helps buyers find the right company by sector and country. Every company has a profile showing what it does, what it offers and how to get in touch.

Is it free to list my company?

Yes, and it stays free: no card, no paid tier. Your profile appears in search results and category pages, can show up to 20 products and services, and lets buyers message you or ask for a quote.

How does verification work, and what does it cost?

Verifying your company is free. Confirm a code we email to an address at your company’s website, or send a company registration document for our team to check, and the verified badge appears on your profile. To show the badge in the directory and search results as well, take out a subscription: the first 14 days are free, and the price is on our pricing page.

Where does the company information come from?

Most profiles are built from public sources, such as official company registers. Claim your company’s profile to correct its details and add your own.

How do I claim or correct my company’s profile?

Open your company’s profile and choose Claim Profile. If you use an email address at your company’s website, a 6-digit code makes the profile yours at once; otherwise our team reviews your request, usually within a few days. Spotted a mistake on a company that isn’t yours? Tell us through our contact page.
