Firewall Configuration

We start by understanding your site and traffic. We note the platform, hosting type, traffic level, countries your customers come from, key integrations such as payment gateways, CRM webhooks, mobile apps and booking tools, and recent security events. We then decide where the firewall should sit. There are three common layers. A cloud or DNS-level firewall, such as Cloudflare, filters traffic before it reaches your server and can also provide caching and denial-of-service protection. A server-level firewall, such as ModSecurity or the host’s own WAF, runs on the web server. A plugin-level firewall runs inside WordPress and is easier to manage but protects later in the chain. Many sites benefit from a cloud layer plus a plugin. We choose according to your hosting, budget and skills. If a cloud firewall is chosen, we change DNS carefully; see domain DNS configuration. Before activating, we record normal traffic patterns for several days where possible, so we can tell abnormal from normal. We then apply rules. We enable managed rule sets that cover well-known attacks such as SQL injection, cross-site scripting and file inclusion. We add rate limits on login, XML-RPC, search and form submission endpoints. We set bot rules that allow major search engines, uptime monitors and legitimate tools, and challenge or block known bad bots, scrapers and suspicious user agents. We consider country or network rules: for a local business serving only India, challenging traffic from irrelevant regions may reduce abuse, but we avoid blanket blocks that could harm customers abroad or travellers. We protect the admin area by limiting access to trusted IPs when practical or requiring extra verification. We add exceptions for trusted services, such as payment gateway callbacks, WhatsApp or CRM webhooks, and Google crawlers, so integrations keep working. Then we test. We run the site through normal flows: browsing, search, forms, checkout and login. We simulate typical blocked requests safely in a controlled way, and we use the firewall’s preview or log-only mode to review what would have been blocked. We check that search engine crawling is unaffected through Search Console; see Core Web Vitals optimization for the speed side. After going live, we monitor logs closely for the first week and fix any false positives. We set alerts for spikes in blocked traffic. We document the rules, exceptions and how to disable the firewall temporarily in an emergency. We recommend a monthly log review, and we can provide this through website maintenance plans. We cannot stop every attack or guarantee uptime during very large denial-of-service attacks without specialised services, but a configured firewall removes a large share of routine malicious traffic.
