Overcomplicating zero trust policies without a rollout plan
Cloudflare Zero Trust can require careful policy design to avoid overblocking or access gaps, and it can surprise teams when advanced routing and clientless behaviors appear in practice. Zscaler Zero Trust Exchange can also slow rollout when complex policy design spans large app portfolios, so segmentation and policy scope should be planned early.
Relying on SD-WAN steering without testing session continuity rules
Fortinet FortiGate SD-WAN can break session continuity if SD-WAN rules are misconfigured, especially when link health or SLA thresholds change quickly. A controlled test of application-aware steering behavior helps prevent unexpected session changes across WAN links.
Creating alert noise by using default thresholds and no tuning
Paessler PRTG Network Monitor alerts can increase noise without well-tuned thresholds and exclusions in large environments. SolarWinds Network Performance Monitor alert rules also need careful thresholds to avoid noise and false positives, so alert baselines should be established before scaling.
Choosing packet capture tools when protocol-level evidence is not required
