Imperva Advanced Bot Protection vs. Arcjet

Automated bot attacks have become a major security concern for businesses across industries. From credential stuffing to web scraping and fraud, malicious bots target websites, APIs, and mobile applications, posing significant risks to data, customer trust, and revenue. As automation now dominates how digital services are accessed, and AI increases the scale and sophistication of these threats, organizations face growing challenges in distinguishing between legitimate and malicious activity.

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.
