Nexusguard
Pros
- + Flat-rate pricing that does not penalize customers during attacks
- + True Hybrid architecture: on-site Bastions appliances plus global cloud scrubbing with automatic spill-over
- + Eighteen-year track record inside 100+ CSPs protecting 50,000+ ASNs
- + DNS Protection with a guaranteed 100% availability SLA
- + Geolocation-aware scrubbing routing with automatic health-check failover
- + White-label DDoS-protection-as-a-service program for carriers and MSSPs
Cons
- - No public pricing, no free tier, no self-service onboarding — quote-only sales engagement
- - Deployment requires DNS rerouting, BGP, or GRE tunnels: real setup complexity
- - CSP-first product roadmap; enterprises are often served through resellers
- - WAF is a layered add-on, not a standalone application-security platform
- - Scrubbing-center count is inconsistent across the vendor's own pages (40+ vs 50+)
ModSecurity
Pros
- + Free Apache-2.0 WAF engine with 23 years of production deployments behind it
- + OWASP Core Rule Set covers OWASP Top 10 attack classes without application-specific knowledge
- + Actively maintained under OWASP governance with LTS rule branches and coordinated security releases
- + Full control and visibility: custom rules, blocking or detection-only modes, everything on your own servers
- + Broad deployment surface: Apache, nginx, IIS, containers, Debian/Ubuntu packages
Cons
- - Engine alone provides almost no protection — CRS tuning is mandatory skilled work
- - False positives are guaranteed without a detection-only tuning period; not a deploy-and-forget tool
- - libmodsecurity 3.x connector path (nginx/IIS) has matured more slowly than the Apache module
- - No volumetric DDoS protection, no managed option, no SLA, community-only support
