Build the UK growth engine for one of the world’s most differentiated Managed XDR providers.
LMNTRIX is looking for an accomplished cybersecurity sales leader to take ownership of our growth across the United Kingdom.
This is not a role for someone who wants to inherit a mature territory and manage an existing pipeline. It is an opportunity for an entrepreneurial sales executive to build a significant UK business with the backing of a globally established cybersecurity company, a differentiated platform and direct access to senior engineering and executive leadership.
About LMNTRIX
LMNTRIX is a globally recognised Managed Extended Detection and Response provider.

Our unified MXDR platform provides coverage across 13 security domains, including:
- Endpoint
- Network
- Cloud
- Identity
- Next-Generation SIEM
- Mobile
- OT and IoT
- Deception
- Threat intelligence
- Dark web and external attack-surface monitoring
- Full-packet forensics

LMNTRIX has been:
- Positioned as a Leader in the IDC MarketScape for Worldwide Emerging Managed Detection and Response Services

- Recognised among the world’s Top 250 MSSPs by MSSP Alert
- Highly rated by customers across Gartner Peer Insights and G2
We support organisations across multiple countries and industries, working through both direct customer relationships and an established global partner ecosystem.
