Technology Partner Highlight

Stellar Cyber helps bring together telemetry from across the security environment, supporting RSM's broader managed security strategy around integration, operational consistency and measurable client outcomes.

Cybersecurity leaders are not struggling because they lack tools. In many cases, they have more security technology than they can operationalize. Detection tools, identity platforms, cloud controls, vulnerability data, compliance workflows and incident response processes often sit across different systems, teams and providers. The result is a security program that may look mature on paper but still feels fragmented in practice.

That fragmentation creates real business risk. Alerts are harder to prioritize. Investigations take longer. Identity risk is separated from security operations. Compliance activity becomes disconnected from threat reality. Executives receive incomplete views of risk, while security teams spend too much time correlating data and too little time making decisions.

This is the challenge RSM is focused on helping clients solve.

Building a More Connected Security Operating Model

As organizations continue to face more complex cyber threats, tighter regulatory expectations and ongoing talent constraints, the next generation of managed security needs to be more than outsourced monitoring. Clients need a connected operating model that brings technology, process and security expertise together in a way that improves visibility, accelerates response and supports better business decisions.

That is where the collaboration between RSM and Stellar Cyber becomes meaningful.

Stellar Cyber's open XDR platform helps bring together telemetry from across the security environment, giving analysts a more unified view of activity across systems and reducing the manual effort required to move between disconnected tools. For RSM, that capability supports a broader managed security strategy built around integration, operational consistency and measurable client outcomes.

RSM's managed security services are designed to help organizations strengthen their security posture without having to build every capability internally. The firm's portfolio includes managed detection and response, managed SOC, XDR, incident response, cloud security, vulnerability management, compliance, identity governance, privileged access management, operational technology security and broader cybersecurity advisory services.

But the value is not simply in the list of services. The value is in how those capabilities come together.

Turning Security Visibility Into Action

By combining RSM's security operations experience, identity and governance capabilities, incident response expertise and managed services delivery model with Stellar Cyber's platform, clients can move toward a more connected view of risk. Security operations can better inform identity priorities. Threat detection can be aligned with response readiness. Compliance and governance can be supported by more relevant operational insight. Analysts can spend more time investigating meaningful activity and less time assembling context from fragmented sources.

For middle-market and enterprise organizations, that matters. Many companies are expected to defend against enterprise-level threats but do not have unlimited staff, budget or security engineering capacity. They need managed security partners that can help reduce operational burden while improving maturity. They also need providers that understand that cybersecurity is not only a technology problem; it is a business resilience, governance and execution problem.

The RSM and Stellar Cyber collaboration is built around that reality.

Technology provides the foundation for greater visibility and faster investigation. RSM brings the operating model, security expertise and client context needed to turn that visibility into action. Together, the goal is to help organizations reduce complexity, improve response, and build a cybersecurity program that can scale as their risk profile changes.

“Clients are not asking for more disconnected security activity. They are asking for clarity, accountability and outcomes,” said Steven Kane, Principal in the Cyber practice at RSM US LLP. “Our work with Stellar Cyber supports our broader strategy of helping organizations bring security operations, identity, governance and response together in a more integrated managed services model. That is where we believe clients will see the greatest value.”

As cyber risk continues to evolve, managed security providers will need to do more than monitor alerts or deploy technology. They will need to help clients make sense of complexity, connect risk signals across the enterprise and take action with confidence.

For RSM and Stellar Cyber, the partnership reflects that shift: moving managed security from a collection of capabilities toward a more connected, outcome-focused model for helping clients protect and grow their business.
