FAQs
How are you different from an MSP or MSSP?
Unlike managed service providers, we do not operate or manage your environment. Instead, we provide expert guidance, design, and implementation support so your internal team or provider can execute effectively.
Do you offer managed security services or 24/7 monitoring?
No. We focus on advisory and implementation support rather than ongoing monitoring or managed detection and response. This allows us to remain objective and help clients choose the right solutions for their needs.
What support services do you provide to clients?
We provide cybersecurity consulting focused on security tooling, architecture, and implementation guidance. Our goal is to help organizations make informed decisions, reduce risk, and build effective security programs.
