FAQ
Questions to resolve before work begins.
Do network security services replace a SOC?
Not always. QCS can help prepare the network layer for SOC/MDR by cleaning firewall rules, improving logging, hardening access, and creating incident-ready evidence.
What is SASE readiness?
SASE readiness checks whether SD-WAN, ZTNA, SWG, CASB, FWaaS, remote access, logging, and identity controls are mature enough for a secure cloud-delivered network model.
