Barracuda Web Application Firewall vs. Arcjet

Barracuda Web Application Firewall (WAF) is purpose-built to protect your web, mobile, and API applications from today’s most advanced threats. It helps prevent data breaches and ensures business continuity by blocking OWASP Top 10 attacks, L4–L7 DDoS, zero-day exploits, and more. With Advanced Bot Protection powered by cloud-based machine learning, Barracuda WAF detects and stops malicious bots responsible for web scraping, credential stuffing, and account takeover attempts—before they can do damage.

Arcjet is runtime security for AI agents. It puts the decision where the action is: block prompt injection, stop PII leaks, block bots, and add guardrails to tools, APIs, and database calls. Identity tells you who is asking, but it cannot tell you what happens next. Arcjet runs inside the code that takes the action, so every agent action is observed in the run it belongs to, checked before it executes, and kept as evidence afterwards. Each check returns a decision your code acts on: allow, block, redact, or hold for review.
