SOLUTIONS
Web Application Firewall & DDoS Protection
Your website, customer portal and public APIs are exposed to the whole internet, permanently. We put a cloud WAF in front of them to filter malicious requests, and absorb volumetric attacks before they reach your infrastructure.
What it is
Anything public gets attacked, whether or not anyone knows your name
Public-facing applications are scanned continuously by automated tools looking for known vulnerabilities, exposed admin panels and weak logins. This is not targeted — it is indiscriminate, and a small company in Nicosia is probed as often as a large one in London.
A web application firewall sits in front of the application and inspects every request, blocking SQL injection, cross-site scripting, credential stuffing and the other common attack classes before they reach your code. It also buys you time: when a vulnerability is disclosed in your CMS or framework, a WAF rule can block exploitation while the patch is tested and deployed.
Distributed denial-of-service is the other half. A volumetric attack does not need to breach anything — it simply makes your site unavailable, which for an e-commerce or booking platform is the same as being breached, commercially. Cloud-based mitigation absorbs that traffic upstream, far from your own bandwidth.

Capabilities
What the service covers
OWASP Top 10 protection
SQL injection, cross-site scripting, broken authentication and the rest of the common attack classes are filtered before they reach your application.
Multi-layer DDoS mitigation
Volumetric, protocol and application-layer attacks are absorbed upstream, so your own connection and servers stay available.
Bot & credential-stuffing control
Scrapers, vulnerability scanners and automated login attempts are identified and rate-limited or blocked.
Virtual patching
When a vulnerability is announced in your CMS or framework, a rule can block exploitation immediately while the real patch is tested.
Caching & performance
Because traffic already passes through the edge, static content is cached closer to visitors — security and speed from the same layer.
24/7 monitoring & reporting
Attack volumes, blocked requests and availability are monitored continuously, with reporting you can show to management.

A WAF in blocking mode needs someone who knows the application
Deployed carelessly, a WAF blocks your own customers. Deployed in monitor-only mode forever, it blocks nothing at all.
01
Onboarded without downtime
Traffic is routed through the edge with certificates handled and origin protected, verified in monitoring mode before anything is enforced.
02
Tuned against your application
We review what the rules would have blocked and refine them, so legitimate checkout, upload and login flows are never caught.
03
Watched around the clock
Attack spikes and blocked-request patterns are monitored by our SOC, with escalation when something looks targeted rather than routine.
04
Kept current
Rule sets are updated as new vulnerability classes appear, and virtual patches are applied when something relevant to your stack is disclosed.
FAQ
Questions we get asked
Do we need this if our site is hosted with a good provider?
Hosting providers protect their infrastructure, not your application. A WAF protects the specific requests hitting your code, and DDoS mitigation at their level often means taking your site offline to protect other customers on the same platform.
Will it slow the website down?
Normally the opposite. Traffic passes through an edge network with caching, so most visitors see static content served closer to them. Inspection adds a few milliseconds.
Does a WAF replace fixing the vulnerability?
No. It buys you time and blocks opportunistic exploitation, but the underlying issue still needs patching. Treat virtual patching as a bridge, not a destination.
How large a DDoS attack can be absorbed?
Cloud mitigation operates at a scale no single office connection can match — the relevant question is not size but whether the attack is volumetric or application-layer, and the service covers both.
Do we need to move our hosting?
No. The service sits in front of your existing hosting. The main change is a DNS record and locking the origin so it only accepts traffic from the edge.
