RSM US Deploys Stellar Cyber Open XDR Platform to Secure Clients

San Jose, CA, February 28th, 2024, Cyber Newswire


Platform Delivers Total Visibility and Control Across a Global Client Footprint

Stellar Cyber, the innovator of Open XDR, today announced that RSM US – the leading provider of professional services to the middle market – is leveraging the Stellar Cyber Open XDR platform to unify, expand and control the cybersecurity defenses across its Global MSSP Client Network.

RSM US operates a global managed security operations service, known as RSM Defense, which offers around-the-clock threat detection, response and intelligence services to its clients. As an MSSP, RSM Defense Director and Threat Operations leader Todd Willoughby’s team amassed a collection of discrete client data sources that focus on individual aspects of security, each with a separate console. RSM Defense integrated Stellar Cyber’s Open XDR platform into the MSSP model’s workflow because it unifies those tools and provides SIEM, NDR, UEBA and TPA tools in one comprehensive platform.

“Stellar Cyber is taking a different approach to what’s been offered in the market over the last 15 years,” said Willoughby. “Instead of just putting out just one tool, they are addressing the challenge of delivering a complete view of security events across our clients’ infrastructure under one pane of glass; and because it’s an open platform, integrating clients’ new or existing EDR and other security tools and data sources is a non-issue.”

Other advantages Willoughby found are the platform’s machine learning capabilities and robust, out-of-the-box detection rulesets, which enable him to level the playing field between newer and more skilled security analysts, making them all fully productive. “Great senior cybersecurity analysts are tough to find – even if you can find one, they can cost the business upwards of $150,000 a year, and most clients can’t afford that,” he said.

“Enterprises and MSSPs providing cybersecurity protection for multiple sites or customers need solutions that put them in control with a single pane of visibility, automatic data correlation and analysis, and rapid, bi-directional integrations to client security stack tools,” said Steve Garrison, SVP Marketing at Stellar Cyber. “Our platform delivers on those promises like no other solution in the market.”
