What our shortlists say about the one we picked.
Best for: Mid-market teams wanting built-in WAF and SOC tooling without extra licenses
The anti-ransomware correlation with Sangfor Endpoint Secure and Cyber Command is worth evaluating if you're considering the broader Sangfor ecosystem. The cross-product correlation between network and endpoint telemetry to identify ransomware processes is a real capability, not just a marketing claim. The limitation is that it works best within the Sangfor stack. If you're running a different EDR, the correlation benefit disappears. Sangfor is primarily an on-premises deployment, which suits organizations with data residency requirements or limited cloud connectivity.
