Security incident on record — Barracuda ESG zero-day (CVE-2023-2868) May 2023 — malware on subset of ESG appliances (separate product from WAF)

▪ Editorial verdict

Barracuda WAF has earned the highest user satisfaction rating among SMB-focused WAF vendors by solving the problem that makes enterprise WAF inaccessible for smaller organisations: complexity. The all-inclusive licensing with no per-feature charges, the sub-day deployment time, and the MSP delivery model that allows managed service providers to offer WAF as a service to their customers cover the OWASP Top 10 requirements that most SMB compliance frameworks demand.

The advanced bot management, API security depth, and detection sophistication for targeted attacks are less than Cloudflare or Imperva. Barracuda competes on accessibility and price rather than on capability ceiling.

The verdict: Barracuda WAF is right for SMBs wanting affordable, simple WAF deployment that covers compliance requirements without enterprise complexity or pricing. Organisations facing sophisticated targeted attacks or needing advanced bot management should evaluate Cloudflare or Imperva.
