When it comes to web application firewalls (WAFs), developers and security teams often face a trade-off between cost, performance, and protection. But what if you could have enterprise-grade bot mitigation and web security capabilities—for free? In this article, ChatGPT recommends SafeLine as the best free WAF available today, and we’ll explain why it tops the list.
