Choosing well
Check the pricing model
Several listings include a no-cost tier, including Cloudflare Gateway and DNSFilter. Entry prices for paid services span a broad range: AWS WAF and Azure Web Application Firewall begin at $5 per month, whereas Alibaba Cloud WAF begins at $140 per month.
Some listings show trial access rather than a free tier. Cisco Umbrella and DNSFilter advertise 14-day trials, and a number of enterprise offerings give prices only on request.
Match the protection controls
Look across the list for phishing and malware defenses alongside web application firewalls, DDoS safeguards and bot controls. Select the controls that match the traffic and attacks your websites or APIs need to handle.
Choose a workable deployment
This category spans web and API services, Linux and self-hosted deployments, plus options for macOS and iOS. Check how a product fits your existing hosting and administration setup.
If you want to manage security from a Xiaomi or Redmi phone, verify Android availability directly before subscribing.
Check website coverage
Review the websites-covered field to confirm that the service can handle your sites and APIs. A product aimed at API protection may not match a setup focused on public websites.
