Web applications are the most commonly attacked surface in any organisation. Your websites, e-commerce platforms, customer portals and APIs are accessible from the internet by design, which makes them accessible to attackers by default. A web application firewall sits between your applications and the internet, inspecting every request and blocking malicious traffic before it reaches your systems.
What a managed WAF protects against
SQL injection and cross-site scripting (XSS) - the two most prevalent web application attacks. Attackers inject malicious code through form fields, URL parameters and API inputs to extract data, modify records or take control of user sessions. A WAF detects and blocks these payloads in real time.
DDoS and volumetric attacks - distributed denial-of-service attacks overwhelm your servers with traffic to take your application offline. Our WAF absorbs and filters volumetric traffic at the edge before it reaches your infrastructure, keeping your application available during an attack.
OWASP Top 10 coverage - we configure rulesets that protect against all ten categories of the OWASP Top 10, including broken authentication, sensitive data exposure, security misconfiguration, insecure deserialisation and insufficient logging.
Bot detection and rate limiting - automated scrapers, credential stuffing bots and vulnerability scanners generate enormous volumes of malicious requests. Our WAF identifies and blocks automated traffic while allowing legitimate users through.
Zero-day protection - managed rulesets are continuously updated as new vulnerabilities are disclosed, providing protection against emerging threats before patches are available for the underlying application.
How we deliver it
Our WAF is cloud-hosted and sits in front of your application as a reverse proxy. There is no hardware to install, no software to maintain on your servers and no changes to your application code. DNS changes route traffic through the WAF, which inspects requests and forwards clean traffic to your origin server.
We combine the WAF with a content delivery network (CDN) layer that caches static assets at edge locations worldwide. This improves page load times for your users while providing an additional layer of protection for your origin infrastructure.
Managed means managed
The difference between a WAF that protects you and one that causes problems is in the tuning. An overly aggressive ruleset blocks legitimate customers. An under-tuned ruleset lets attacks through. We manage this balance continuously - monitoring blocked requests, adjusting rules for your specific application behaviour, and escalating genuine threats.
Our managed WAF service includes round-the-clock monitoring, incident escalation, continuous tuning and regular reporting. You get a fixed monthly cost with no upfront investment, no maintenance overhead and no requirement for in-house security expertise to operate it.
Deployment timeline
A managed WAF can be deployed into your existing environment within days. We configure both managed and custom rulesets tailored to your application, conduct initial tuning to avoid false positives, and transition to full managed operations once the ruleset is stable.
