WEB APPLICATION FIREWALL

Web Application Firewall (WAF)

Web Application Firewall (WAF) is a highly sophisticated, configurable firewall that protects your web applications from malicious attacks. Equipped with a comprehensive suite of protective features, WAF sits between external consumers and web applications, safeguarding critical business data from a host of potential threats.

WAF defends against common attacks such as SQL injection, cross-site scripting (XSS), and denial-of-service (DoS) attacks. With its advanced threat detection, customisable rules, and real-time protection, WAF provides robust security that helps maintain the availability, integrity, and confidentiality of your online services.

What is Web Application Firewall (WAF)?

A Web Application Firewall (WAF) is a security tool that monitors and filters HTTP and HTTPS traffic between a web application and the internet. Designed to block threats such as SQL injection, cross-site scripting (XSS), and other web-based attacks, it acts as a protective layer at the application level, helping to ensure that only legitimate traffic is permitted while providing customisable security policies for enhanced protection.


Web Application Firewall (WAF) Features


Amongst many other functions, WAF provides:

  • Web Application Security: This provides complete security for web-based applications from the OWASP (Open Web Application Security Project) Top 10 and many other threats.

  • API Protection: WAF integrates out of the box policies together with an automatically generated positive security model policy based on your schema specification to protect against API exploits.

  • Bot Mitigation: WAF protects against automated bots, webs scrapers, crawlers, data harvesting, credential stuffing and other automated attacks to secure your web assets, mobile APIs, applications, users and sensitive data.

  • CAPTCHA Challenge: You can configure WAF to run CAPTCHA challenges against web requests that match your inspection criteria. CAPTCHA puzzles prove that a human is sending the request.

  • Layer 7 Load Balancing: Layer 7 load balancers route traffic to designated endpoints using data from HTTP/HTTPS requests, enhancing endpoint security against DDoS attacks by concealing IP addresses. They also facilitate quicker failover and precise routing, compared to DNS-only caching.

BENEFITS

Web Application Firewall benefits

Web Application Firewall carries a wide range of functions which has the potential to become complicated to manage, particularly in larger organisations. Every security policy configuration is unique, this is where Cloud Gateway can help.

We collaborate with you to design a bespoke platform solution, tailored to meet your immediate challenges while providing the flexibility to scale and adapt as new technologies emerge.

As part of your managed service, Cloud Gateway become the custodians of your security policy, but you have full control over the rules you want to set for your organisation.

New WAF rules or amendments to policy can be deployed within minutes through the Cloud Gateway portal.

We offer a range of advanced security services to safeguard users, devices and data running across your network.

Implement security functions like FWaaS and SWG, protecting all your traffic as part of a comprehensive network security posture.

This ensures end-to-end protection, safeguarding your network from evolving threats while maintaining seamless, uninterrupted access for authorised users. With Cloud Gateway, you can be confident that your network is secure, resilient, and aligned with best practices in the industry.

The Cloud Gateway portal shows your entire connected ecosystem, via a simple, intuitive dashboard. It's packed full of data, allowing you to keep track of security events, network performance, utilisation and traffic flows in real-time, as well as raise support tickets to our team.

What makes Cloud Gateway's WAF unique?

Cloud Gateway's WAF is designed to integrate with the rest of your connectivity and security ecosystem. It supports centralised management and easy scaling as your needs change.

With a traditional vendor, you get cutting-edge technology. With a Managed Service Provider (MSP) you receive reliable, expert support.

Cloud Gateway is uniquely positioned to offer both of these outcomes. Our tech-enabled managed service seamlessly blends an innovative technology platform with best-in-class experts, to deliver a transformative customer experience that is disrupting the network and security market.

The networking sector is evolving, and we’re committed to leading this change. As businesses demand smarter, more flexible solutions, we harness the power of Network-as-a-Service (NaaS) to provide agile, secure, and future-ready connectivity.

WEB APPLICATION FIREWALL FAQS

Answering your FAQs about WAF

Web Application Firewalls (WAFs) and traditional firewalls serve distinct purposes. WAFs deliver specific protection for web applications by targeting Hypertext Transfer Protocol (HTTP) traffic. Whereas, firewalls focus on overall network security and traffic management across a wider range of traffic types.

Both Secure Web Gateway and Web Application Firewalls enforce specific security policies, helping organisations protect themselves from cyber threats and data breaches, whilst complying with regulatory requirements.

However, their purposes are quite different. A Secure Web Gateway (SWG) is designed to eliminate unwanted software and internet traffic to ensure adherence to corporate and regulatory policies. A Web Application Firewall (WAF) is dedicated to safeguarding web applications from attacks through the filtration and monitoring of HTTP traffic.

Web Application Firewalls (WAF) serve as a protective barrier between the internet and your API server, scrutinising incoming requests to thwart malicious traffic.Conversely, an API Gateway acts as an intermediary between your API server and clients, overseeing access control, traffic direction, and usage restrictions.

Although open-source API gateways can offer comprehensive default security features, emerging threats necessitate a more comprehensive defence approach.

Augmenting your security posture with a specialised Web Application Firewall (WAF) establishes a robust multi-tiered protection framework.

Network firewalls and Web Application Firewalls (WAFs) offer different layers of protection against various threats, working in tandem to fortify cybersecurity defences.

While network firewalls safeguard against attacks at Layers 3 and 4, WAFs concentrate on Layer 7 vulnerabilities, particularly web-based threats. Without a WAF, businesses could still remain vulnerable to web application attacks.

WAFs and network firewalls should be treated as complementary solutions to protect against security risks across your network infrastructure.

A WAF is a crucial component in protecting web applications against DDoS attacks. By implementing rate limiting measures, the WAF effectively mitigates the risk of server overload caused by excessive requests from malicious actors.

Leveraging detection methods such as signature analysis, geolocation tracking, and IP blacklisting, the WAF is able to recognise and block familiar DDoS attack patterns.

Furthermore, the WAF continuously adjusts its defence strategies to counter evolving threats, ensuring real-time protection against emerging DDoS attack techniques.
