Web Application Firewall (WAF) Services
Web applications are one of the most frequently attacked assets on the internet. Every login form, contact form, search field, API endpoint, and checkout page represents a potential entry point for attackers.
At CyberXperts.ai, our Web Application Firewall (WAF) services protect websites and web applications by inspecting, filtering, and blocking malicious traffic before it reaches your servers — reducing risk, downtime, and data exposure.
“If your website is online, it is already being tested by attackers.”
CyberXperts.ai Web Security Reality
Why Web Applications Are Constantly Targeted
Unlike internal systems, web applications are exposed to the public internet 24/7. Attackers do not need insider access — they simply send crafted requests and observe responses.
Web applications are targeted because:
- They directly process user input
- They often interact with databases
- They expose business logic
- They are frequently updated and misconfigured
Even well-developed applications may contain subtle flaws that attackers can exploit at scale.
Common Web Application Attacks
Attackers rely on automated tools to continuously scan and probe websites for weaknesses.
Common attack types include:
- SQL Injection (SQLi): Manipulating database queries to extract or modify data
- Cross-Site Scripting (XSS): Injecting malicious scripts into web pages
- Remote File Inclusion: Executing attacker-controlled files
- Credential Stuffing: Automated login attempts using leaked passwords
- Bot Attacks: Scraping, abuse, or denial-of-service attempts
Many of these attacks do not exploit software bugs — they exploit trust in user input.
What Is a Web Application Firewall (WAF)?
A Web Application Firewall sits between users and your application, inspecting HTTP and HTTPS traffic in real time. It applies security rules to block malicious requests while allowing legitimate traffic to pass.
A WAF acts as a protective shield, reducing exposure to known and emerging attack techniques.
Our Web Application Firewall Approach
CyberXperts.ai deploys and manages WAF solutions using a risk-based, application-aware approach — not generic rule sets.
1. Application Profiling & Risk Analysis
Every application behaves differently. Before enforcing rules, we analyse:
- Application functionality
- Input points and APIs
- User behaviour patterns
- Traffic volume and geography
This prevents false positives that disrupt business operations.
2. Threat Filtering & Rule Enforcement
WAF rules are configured to detect and block:
- Injection attacks
- Malicious payloads
- Abnormal request patterns
- Known exploit techniques
Rules are continuously refined based on observed attack activity.
3. Bot Management & Abuse Prevention
Automated bots are responsible for a significant portion of malicious traffic.
WAF controls help:
- Block credential stuffing attacks
- Prevent scraping and content theft
- Limit brute-force login attempts
- Reduce denial-of-service impact
4. Continuous Monitoring & Tuning
Web attacks evolve constantly. Static configurations quickly become ineffective.
WAF activity feeds into:
Real-World WAF Scenarios
In one ecommerce case, attackers attempted credential stuffing against customer accounts. The WAF identified abnormal login rates and blocked the attack before account takeovers occurred.
In another incident, an unpatched plugin exposed a vulnerable endpoint. The WAF blocked exploit attempts until a permanent fix could be applied, preventing data compromise.
Why WAF Is Not a Replacement for Secure Development
A WAF is a powerful defensive layer, but it does not replace secure coding practices or vulnerability management.
It works best when combined with:
Who Needs Web Application Firewall Services?
WAF services are critical for organisations that:
- Operate public websites or web portals
- Run ecommerce or SaaS platforms
- Expose APIs to partners or customers
- Handle sensitive or regulated data
- Experience frequent web-based attacks
Web Application Firewall – FAQs
Is a WAF the same as a network firewall?
No. A network firewall controls traffic at the network level, while a WAF inspects application-layer traffic.
Will a WAF slow down my website?
Properly configured WAF solutions are designed to minimise latency while providing protection.
Can a WAF block zero-day attacks?
WAFs can block many zero-day attacks by detecting malicious behaviour patterns, even without known signatures.
Does a WAF eliminate the need for secure coding?
No. A WAF is a compensating control, not a replacement for secure development.
How often should WAF rules be updated?
Continuously. Threats and application behaviour change over time.
Web Application Firewall services from CyberXperts.ai provide a critical protective layer — reducing exposure, blocking attacks, and keeping web-facing systems resilient against modern threats.
