About Critical Start

Critical Start was founded in 2012 with a focus on eliminating the trust deficit between MSSPs and their clients by providing full transparency into every alert decision made by their SOC analysts. Their Trusted Behavior Registry (TBR) methodology allows clients to define approved behaviors, reducing false positives and ensuring every alert that reaches the client represents a genuine threat. Their CORR platform integrates endpoint, network, cloud, and identity telemetry, delivering 24/7 MDR with full analyst decision transparency and detailed audit trails. Critical Start has been recognized in Gartner's Market Guide for MDR and was acquired by Lumifi Cyber in 2024, expanding their combined MDR capabilities. Their transparent operations model remains a key differentiator for security-conscious mid-market and enterprise organizations.

What Should You Ask When Evaluating Critical Start?

Before engaging any MSSP, use these questions to assess whether the provider is the right fit for your organization. These apply to Critical Start and any other provider on your shortlist.

What is included in the base service vs. what costs extra? Clarify whether incident response, compliance reporting, and additional log source onboarding are included or billed separately.
What response actions does the provider take directly? Some MSSPs only send alerts for your team to act on. Others take containment actions like host isolation or account lockout on your behalf.
What does the onboarding process look like? Ask about typical onboarding timelines, how much work your team needs to put in, and when full monitoring coverage goes live.
Can you provide references from similar organizations? Ask for references from companies in your industry and size segment. The experience of similar organizations is the best predictor of how the MSSP will perform for you.
What happens if we need to switch providers? Understand data portability, contract termination terms, and transition support. A transparent exit process is a sign of a provider that prioritizes long-term trust over lock-in.
