Web Application Firewall (WAF) Protection
Websites, customer portals and APIs are open to the whole internet by design, which makes them a constant target. VOWTECH deploys, tunes and supports web application firewalls for organisations in Abu Dhabi, Dubai and across the UAE, filtering malicious requests before they reach your application.
Protection That Understands Web Traffic
A network firewall decides which ports are open. For a public website, the web ports have to be open to everyone, so the network firewall lets all of that traffic through, good and bad alike. A web application firewall sits in front of the application and reads each request, looking for injection attempts, cross-site scripting, credential stuffing and other abuse hidden inside otherwise normal-looking traffic.
A WAF is valuable whenever a business runs something customers or staff log into over the internet: an e-commerce site, a booking system, a client portal, a web-based ERP or an API feeding a mobile app. It is especially useful where the application cannot be patched quickly, because rules can shield a known weakness while developers prepare a fix.
VOWTECH helps you choose between cloud-based and on-premises options, deploys the WAF alongside your existing firewall and load balancers, and tunes it so genuine visitors are not blocked. Pairing it with periodic penetration testing confirms the protection holds.
Three Ways to Deploy a WAF
The right model depends on where your application is hosted, how much traffic it handles and who will manage it.
Cloud-Based WAF
Traffic is directed through a cloud service, usually by a DNS change, where it is filtered before reaching your server. Quick to adopt and well suited to sites hosted with a provider.
On-Premises or Virtual Appliance
A physical or virtual WAF is placed in your own data centre or private cloud, in front of the web servers. Traffic and decrypted data stay within infrastructure you control.
Integrated or Host-Based WAF
WAF capability built into a reverse proxy, application delivery controller, firewall or the web server itself. A practical option for smaller applications or as an additional layer.
Web Application Firewall Services
A WAF is only as good as its tuning. These services cover the whole life of the deployment.
WAF Deployment
Selection, installation and network integration of the WAF, including DNS or routing changes, certificates and high availability, planned to avoid downtime for the application.
Policy Tuning
The WAF first runs in monitoring mode while we study what it would block. Rules are adjusted to fit your application before blocking is enabled, keeping false positives low.
Protection Against Common Web Attacks
Rule sets address the widely recognised categories of web application risk: SQL injection, cross-site scripting, file inclusion, broken authentication abuse and similar techniques.
Bot & Request Flood Mitigation
Rate limiting, challenge pages and reputation data separate real visitors from scrapers, credential-stuffing tools and application-layer floods aimed at exhausting your server.
API Security
APIs are checked against their expected structure, with authentication enforced and abnormal call patterns limited, protecting the back end behind mobile and partner integrations.
Monitoring & Reporting
Blocked requests, attack trends and rule performance are reviewed, policies are updated when the application changes, and events can be passed to threat detection and response.
From Application Review to Active Protection
Blocking is switched on only after the WAF has learned what normal traffic looks like.
Assessment
We review the applications, hosting, traffic patterns, certificates and any known weaknesses.
Planning
Deployment model, traffic path, rule sets and a rollback plan are agreed with your developers.
Deployment
The WAF is installed or provisioned and traffic is routed through it in monitor-only mode.
Configuration & Tuning
Logged events are analysed, exceptions are defined and blocking is enabled in stages.
Monitoring
Attack activity and false positives are watched, and policies are kept in step with releases.
Why Put a WAF in Front of Your Application
Application-layer attacks pass straight through ordinary network defences. A WAF is the control designed for them.
Virtual Patching
A rule can block exploitation of a known flaw while the underlying code or platform waits for a proper fix.
Customer Data Protected
Login forms, payment pages and personal data sit behind an extra layer that inspects every request.
Servers Spared the Noise
Filtering bots and junk requests upstream leaves capacity for genuine visitors.
Tuned and Supported
VOWTECH, based in Abu Dhabi with support available 24/7, keeps policies current as your application evolves.
Web Application Firewall Questions
How is a WAF different from a normal firewall?
Will a WAF block legitimate visitors or slow the site down?
Should we choose a cloud or an on-premises WAF?
If we have a WAF, do we still need security testing?
