Web application firewall for Adelaide websites

Your website is under attack right now — automated bots are constantly probing for vulnerabilities, trying SQL injection, brute-forcing login pages and looking for outdated plugins to exploit. A web application firewall sits in front of your site and blocks these attacks before they reach your server. We set it up and manage it so your site stays protected without you having to think about it.

What is a web application firewall?

A web application firewall (WAF) filters and monitors HTTP traffic between the internet and your website. It blocks common attacks like SQL injection (attackers trying to access your database), cross-site scripting (injecting malicious code into your pages), and brute force login attempts. Unlike a network firewall that protects your server, a WAF specifically understands web traffic and can distinguish between legitimate visitors and malicious requests.

What we protect against

SQL injection blocking

Requests that try to manipulate your database through form fields or URLs detected and blocked before they reach your application.

Cross-site scripting (XSS) prevention

Attempts to inject malicious scripts into your pages that could steal visitor data or redirect users to harmful sites.

Brute force protection

Automated login attempts rate-limited and blocked so attackers can't guess their way into your admin panel or user accounts.

Bot management

Malicious bots blocked while legitimate crawlers like Google are allowed through — keeping your site accessible without being vulnerable.

Virtual patching

Known vulnerabilities in your CMS or plugins blocked at the WAF level even before you've had a chance to update the software.

Custom rules

Specific rules configured for your site's needs — blocking suspicious countries, protecting sensitive pages or rate-limiting particular endpoints.

Who it's for

Businesses running WordPress, WooCommerce or other CMS platforms that are frequent targets for automated attacks.
Ecommerce sites that handle customer data and can't afford a breach.
Organisations that have been hacked before and want a proper layer of protection in front of their site.
Any Adelaide business that wants their website protected from attacks without needing to become a security expert.

How it works

Assess your attack surface. We review your website platform, plugins, login pages and any forms or APIs to understand where the vulnerabilities are.
Deploy the WAF. A cloud-based WAF configured in front of your website — all traffic filtered through it before reaching your server, with no changes needed to your site.
Configure the rules. Standard OWASP protection enabled, plus custom rules tuned for your specific platform, plugins and traffic patterns.
Test and tune. We verify the WAF isn't blocking legitimate traffic, adjust sensitivity levels and make sure your site functions perfectly behind the firewall.
Monitor and update. Attack logs reviewed regularly, rules updated as new threats emerge and custom adjustments made as your site evolves.

Why WaTo for WAF protection

We configure WAF rules specifically for your website, not just turn on generic protection and hope it works.
We manage your hosting, CDN and WAF together — so all the layers work as one system, not separate products from different providers.
Adelaide-based support since 2001 — if the WAF is blocking something it shouldn't, we fix it fast.
We monitor the attack logs so we know what threats your site is facing and can adjust protection accordingly.
Virtual patching means known vulnerabilities are blocked immediately, buying you time to update software without being exposed.

Web application firewall questions

Will a WAF slow down my website?

No. Cloud-based WAFs add only a few milliseconds of latency — unnoticeable to your visitors. When combined with a CDN (which most WAF providers include), your site often ends up faster than before because static content is cached at the edge.

Can a WAF block legitimate visitors?

It can if not configured properly, which is why we tune the rules for your specific site. We start in monitoring mode to identify any false positives before switching to full blocking, and we adjust rules as needed.

Do I still need to update my software if I have a WAF?

Yes. A WAF is a layer of protection, not a substitute for keeping your site up to date. Virtual patching buys you time, but the underlying vulnerability should still be fixed with a proper software update.

What attacks does a WAF not protect against?

A WAF protects against web application attacks — it won't stop someone with stolen admin credentials, server-level vulnerabilities or social engineering. That's why it's part of a broader security approach, not the only layer.
